Description

空调系统Air Conditioning System

技术领域technical field

本发明涉及一种空调系统，尤其是涉及可进行室内取暖的空调系统。The invention relates to an air-conditioning system, in particular to an air-conditioning system capable of indoor heating.

背景技术Background technique

一直以来，作为可进行室内取暖的空调系统，有在具有蒸气压缩式制冷剂回路的热源单元上连接放热器、风扇对流式取暖器等室内取暖装置而构成的系统(例如参照专利文献1、2及3)。这种空调系统通过对室内的地面和室内空气进行加热来实现室内的取暖。Conventionally, as an air-conditioning system capable of heating a room, there is a system configured by connecting a radiator, a fan convection heater, and other room heating devices to a heat source unit having a vapor compression refrigerant circuit (for example, refer to Patent Document 1, 2 and 3). This air conditioning system realizes indoor heating by heating the indoor ground and indoor air.

另外，作为这种空调系统的热源单元有时使用具有以二氧化碳为制冷剂的制冷剂回路的单元。在这种以二氧化碳为制冷剂的热源单元中，由于可提高压缩机排出侧的制冷剂温度，因此，例如在空调系统构成为将在热源单元的利用侧热交换器中被加热的载热体的热量通过室内取暖装置向室内放出的场合等，能提高室内取暖装置中可用于室内取暖的温度水平。由此，可实现舒适的室内取暖。In addition, as a heat source unit of such an air conditioning system, a unit having a refrigerant circuit using carbon dioxide as a refrigerant may be used. In such a heat source unit using carbon dioxide as a refrigerant, since the temperature of the refrigerant on the discharge side of the compressor can be increased, for example, the air conditioning system is configured as a heat carrier that will be heated in the heat exchanger on the utilization side of the heat source unit. In occasions where the heat of the indoor heating device is released to the room through the indoor heating device, the temperature level that can be used for indoor heating in the indoor heating device can be increased. Thereby, comfortable indoor heating can be realized.

发明公开invention disclosure

在利用上述空调系统对高气密性住宅内的空气进行调节时，为了维持室内空气环境(以下称为IAQ)，需要进行室内的必要最低限度的换气。但是，在冬季等室外空气处于低温的场合(以下称为室外空气温度低时)，温度比室内空气温度低的室外空气作为换气用空气向室内供给，因此，产生室内换气所引起的取暖负荷(以下称为换气取暖负荷)。该换气取暖负荷在换气用空气向室内供给而与室内空气混合后，由室内取暖装置进行处理，因此，成为使室内居住者感到因供给低温的换气用空气而引起的不适感(以下称为冷风)的主要原因。尤其是近年来，在高气密性的基础上还附加了高隔热性的高气密及高隔热性住宅逐渐增加，在这种高气密及高隔热性住宅中，虽然因隔热性能提高而可减少取暖负荷的总量，但却不能使维持IAQ所需的换气取暖负荷减少，因此，换气取暖负荷在空调系统处理的取暖负荷总量中所占的比例相对变大。因此，在可进行室内取暖的空调系统中，期望既能处理换气取暖负荷又可防止冷风。When the air in a highly airtight house is conditioned by the air-conditioning system described above, it is necessary to carry out minimum necessary ventilation in the room in order to maintain the indoor air environment (hereinafter referred to as IAQ). However, when the outdoor air is at low temperature in winter (hereinafter referred to as low outdoor air temperature), the outdoor air whose temperature is lower than the indoor air temperature is supplied to the room as ventilation air, and therefore heating due to indoor ventilation occurs. load (hereinafter referred to as ventilation and heating load). This ventilation and heating load is processed by the room heating device after the ventilation air is supplied into the room and mixed with the room air, so that the indoor occupants feel discomfort caused by the supply of low-temperature ventilation air (hereinafter known as the main cause of cold wind). Especially in recent years, on the basis of high airtightness, high airtightness and high heat insulation houses with high heat insulation are gradually increasing. In such high airtightness and high heat insulation houses, although the insulation The improvement of thermal performance can reduce the total heating load, but it cannot reduce the ventilation and heating load required to maintain IAQ. Therefore, the proportion of ventilation and heating load in the total heating load handled by the air conditioning system is relatively larger . Therefore, in an air conditioning system capable of heating a room, it is desired to be able to handle the ventilation and heating load while preventing cold wind.

在使用上述以二氧化碳为制冷剂的热源单元时，虽然能提高室内取暖装置中可利用的温度水平，但会使利用侧热交换器的出入口处的温差变小，结果是，热源单元的性能系数(以下称为COP)降低。因此，在使用以二氧化碳为制冷剂的热源单元的、可进行室内取暖的空调系统中，期望提高COP。When using the above-mentioned heat source unit using carbon dioxide as the refrigerant, although the temperature level available in the indoor heating device can be increased, the temperature difference at the inlet and outlet of the heat exchanger on the utilization side will be reduced. As a result, the performance coefficient of the heat source unit (hereinafter referred to as COP) decreased. Therefore, in an air conditioning system capable of heating a room using a heat source unit using carbon dioxide as a refrigerant, it is desired to increase the COP.

本发明所要解决的技术问题是在可进行室内取暖的空调系统中防止为了进行室内换气而向室内供给的换气用空气引起冷风。The technical problem to be solved by the present invention is to prevent cold wind caused by ventilation air supplied to a room for indoor ventilation in an air-conditioning system capable of heating the room.

第一发明的空调系统，可进行室内取暖，包括热源单元、供气装置、载热体回路。热源单元具有包含压缩机、热源侧热交换器、膨胀机构、利用侧热交换器的蒸气压缩式制冷剂回路，在利用侧热交换器中可对用于室内取暖的载热体进行加热。供气装置将室外空气作为换气用空气向室内供给。载热体回路具有：将在利用侧热交换器中被加热的载热体的热量向室内放出的一个以上的室内取暖装置、以及利用在利用侧热交换器中被加热的载热体的热量对换气用空气进行加热的室外空气加热用热交换装置，使载热体在所述室内取暖装置与所述利用侧热交换器之间以及所述室外空气加热用热交换装置与所述利用侧热交换器之间进行循环。The air conditioning system of the first invention can be used for indoor heating, and includes a heat source unit, an air supply device, and a heat carrier circuit. The heat source unit has a vapor compression refrigerant circuit including a compressor, a heat source side heat exchanger, an expansion mechanism, and a utilization side heat exchanger, and the utilization side heat exchanger can heat a heating medium used for indoor heating. The air supply device supplies outdoor air into the room as ventilation air. The heating medium circuit includes: one or more indoor heating devices that release the heat of the heating medium heated in the use-side heat exchanger to the room; A heat exchange device for heating outdoor air for heating air for ventilation, the heating medium is passed between the indoor heating device and the heat exchanger on the utilization side, and between the heat exchange device for heating outdoor air and the utilization side heat exchanger. Circulation between side heat exchangers.

在该空调系统中，由压缩机压缩后排出的高温高压的制冷剂在利用侧热交换器中对载热体进行加热。在该利用侧热交换器中被加热的载热体向一个以上的室内取暖装置输送，将载热体的热量向室内放出来进行室内的取暖，另外，在该利用侧热交换器中被加热的载热体向室外空气加热用热交换装置输送，对通过供气装置作为换气用空气向室内供给的室外空气进行加热。并且，在室内取暖装置及室外空气加热用热交换装置中进行了室内取暖及换气用空气加热后的载热体重新返回到利用侧热交换器中。另一方面，在利用侧热交换器中对载热体加热而冷却的制冷剂由膨胀机构减压，并在热源侧热交换器中被加热而成为低压的制冷剂后，重新吸入到压缩机中。另外，所谓室内取暖装置例如是指放热器、风扇对流式取暖器、地面取暖装置等。这样，在该空调系统中，由于具有室外空气加热用热交换装置，故在进行室内取暖时，可对换气用空气进行加热后再向室内供给。由此，可防止为了进行室内的换气而向室内供给的换气用空气引起冷风，可提高室内的舒适性。In this air conditioning system, the high-temperature and high-pressure refrigerant discharged after being compressed by the compressor heats the heat carrier in the utilization-side heat exchanger. The heating medium heated in the use-side heat exchanger is transported to one or more indoor heating devices, and the heat of the heating medium is released into the room for indoor heating. In addition, the heating medium is heated in the use-side heat exchanger. The heating medium is sent to the heat exchange device for heating outdoor air, and the outdoor air supplied to the room as ventilation air by the air supply device is heated. And, the heating medium heated for indoor heating and ventilation air in the indoor heating device and the heat exchange device for outdoor air heating is returned to the use-side heat exchanger. On the other hand, the refrigerant heated and cooled by the heat medium in the use side heat exchanger is decompressed by the expansion mechanism, heated in the heat source side heat exchanger to become a low-pressure refrigerant, and sucked into the compressor again. middle. In addition, the so-called indoor heating means, for example, radiators, fan convector heaters, floor heating devices, and the like. In this manner, since the air conditioning system includes the heat exchange device for heating the outdoor air, when the room is heated, the air for ventilation can be heated and then supplied to the room. Thereby, it is possible to prevent the ventilation air supplied to the room for indoor ventilation from causing cold wind, and it is possible to improve indoor comfort.

第二发明的空调系统，在第一发明的空调系统中，载热体回路与利用侧热交换器连接，使在利用侧热交换器中被加热的载热体依次向室内取暖装置、室外空气加热用热交换装置供给。In the air-conditioning system of the second invention, in the air-conditioning system of the first invention, the heating medium circuit is connected to the heat exchanger on the utilization side, so that the heating medium heated in the heat exchanger on the utilization side is sequentially supplied to the indoor heating device, the outdoor air Heating is supplied by a heat exchange device.

在该空调系统中，载热体回路与利用侧热交换器连接，使在利用侧热交换器中被加热的载热体依次向室内取暖装置、室外空气加热用热交换装置供给，因此，在室内取暖装置中，可利用在利用侧热交换器中被加热后的高温载热体的热量，在室外空气加热用热交换装置中，可利用在室内取暖装置中向室内放热而冷却后的载热体的热量。在此，由于通过供气装置向室内供给的换气用空气的温度比室内空气低，因此，可利用在室内取暖装置中向室内放热而冷却后的载热体对其进行加热。并且，用于在室外空气加热用热交换装置中对向室内供给的换气用空气进行加热的载热体在对换气用空气进行加热而进一步冷却后，返回到利用侧热交换器中。这样，在该空调系统中，将在室内取暖装置中放热而冷却的载热体向室外空气加热用热交换装置供给，用于对向室内供给的换气用空气进行加热，因此，可加大利用侧热交换器的出入口处的温差，提高热源单元的COP。In this air conditioning system, the heating medium circuit is connected to the heat exchanger on the use side, and the heat medium heated in the heat exchanger on the use side is supplied to the indoor heating device and the heat exchange device for heating outdoor air in sequence. In the indoor heating device, the heat of the high-temperature heat carrier heated in the heat exchanger on the utilization side can be used, and in the heat exchange device for heating outdoor air, the heat released from the indoor heating device to the room and cooled can be used. The heat of the heat carrier. Here, since the temperature of the ventilation air supplied into the room by the air supply device is lower than that of the room air, it can be heated by the heating medium cooled by the room heater radiating heat into the room. Then, the heating medium used for heating the ventilation air supplied to the room in the outdoor air heating heat exchange device heats and further cools the ventilation air, and then returns to the use-side heat exchanger. In this way, in this air conditioning system, the heating medium cooled by the indoor heating device is supplied to the heat exchange device for heating outdoor air, and is used to heat the ventilation air supplied to the room. Large temperature difference between the inlet and outlet of the heat exchanger on the utilization side improves the COP of the heat source unit.

在该空调系统中，载热体回路还具有对室内取暖装置及室外空气加热用热交换装置中的至少一个进行旁通的旁通载热体回路，因此，可根据需要仅向室内取暖装置及室外空气加热用热交换装置中的一部分供给载热体。另外，因为旁通载热体回路具有“至少一个”，故可以分别与室内取暖装置及室外空气加热用热交换装置对应地设置，也可仅与一部分对应地设置，或者也可设置成对室内取暖装置及室外空气加热用热交换装置中的几个集中起来进行旁通的形态。In this air conditioning system, the heating medium circuit further has a bypass heating medium circuit that bypasses at least one of the indoor heating device and the heat exchange device for heating outdoor air, so that only the indoor heating device and the outdoor air heating A part of the heat exchange device for heating outdoor air supplies the heating medium. In addition, since there is "at least one" bypass heating medium circuit, it may be installed corresponding to the indoor heating device and the heat exchange device for outdoor air heating, or may be provided corresponding to only a part, or may be installed in pairs.

在该空调系统中，旁通载热体回路具有载热体流量调节机构，因此，可调节向设有旁通载热体回路的室内取暖装置及室外空气加热用热交换装置中的至少一部分供给的载热体的流量。另外，所谓载热体流量调节机构是指根据需要切断在旁通载热体回路中流动的载热体的电磁阀、或调节在旁通载热体回路中流动的载热体的流量的电动阀等。In this air conditioning system, since the bypass heating medium circuit has a heating medium flow rate adjustment mechanism, it is possible to adjust the supply to at least a part of the indoor heating device and the outdoor air heating heat exchange device provided with the bypass heating medium circuit. The flow rate of the heat carrier. In addition, the so-called heating medium flow regulating mechanism refers to a solenoid valve that cuts off the heating medium flowing in the bypass heating medium circuit or an electric motor that adjusts the flow rate of the heating medium flowing in the bypass heating medium circuit. valve etc.

第五发明的空调系统，在第一发明的空调系统中，载热体回路由多个分割载热体回路构成，该多个分割载热体回路使载热体在室内取暖装置与利用侧热交换器之间以及/或者室外空气加热用热交换装置与利用侧热交换器之间独立循环。In the air-conditioning system of the fifth invention, in the air-conditioning system of the first invention, the heating medium circuit is composed of a plurality of divided heating medium circuits, and the multiple divided heating medium circuits allow the heating medium to be heated between the indoor heating device and the utilization side. Independent circulation between the exchangers and/or between the heat exchange device for heating outdoor air and the heat exchanger on the utilization side.

在此，作为热源单元102的制冷剂回路120的工作制冷剂可以使用HCFC制冷剂、HFC制冷剂、HC制冷剂或二氧化碳，但在本实施例中，使用临界温度低的二氧化碳，可实现压缩机121排出侧的制冷剂压力在制冷剂的临界压力以上的超临界制冷循环。在作为制冷剂使用二氧化碳的超临界制冷循环中，由于压缩机121排出侧的制冷剂压力上升，从而可提高压缩机121排出侧的制冷剂温度、即载热体-制冷剂热交换器122的制冷剂入口处的制冷剂温度。另外，流入载热体-制冷剂热交换器122的制冷剂由压缩机121压缩到临界压力以上，故在载热体-制冷剂热交换器122中，超临界状态的制冷剂对载热体进行加热。Here, as the working refrigerant of the refrigerant circuit 120 of the heat source unit 102, HCFC refrigerant, HFC refrigerant, HC refrigerant or carbon dioxide can be used, but in this embodiment, the use of carbon dioxide with a low critical temperature can realize compressor 121 A supercritical refrigeration cycle in which the refrigerant pressure on the discharge side is above the critical pressure of the refrigerant. In a supercritical refrigeration cycle in which carbon dioxide is used as a refrigerant, since the pressure of the refrigerant on the discharge side of the compressor 121 increases, the temperature of the refrigerant on the discharge side of the compressor 121, that is, the temperature of the heat medium-refrigerant heat exchanger 122 can be increased. Refrigerant temperature at the refrigerant inlet. In addition, the refrigerant flowing into the heat carrier-refrigerant heat exchanger 122 is compressed by the compressor 121 to above the critical pressure, so in the heat carrier-refrigerant heat exchanger 122, the refrigerant in the supercritical state for heating.

地面取暖装置143例如配置在建筑物U的地面下，是主要具有将载热体的热量通过设于地面的传热面板向室内放出的地面取暖用配管143a的装置。The floor heating device 143 is arranged, for example, under the floor of the building U, and mainly includes a floor heating pipe 143a for dissipating the heat of the heating medium indoors through a heat transfer panel provided on the floor.

室外空气加热用热交换装置144例如配置在室外，是主要具有利用载热体的热量对通过供气装置103向室内供给的换气用空气进行加热的室外空气加热用热交换器144a的装置(在此，在室外空气加热用热交换器144a中进行热交换后向室内供给的供给空气在图1中用SA3表示)。The heat exchange device 144 for heating outdoor air is arranged outdoors, for example, and mainly includes a heat exchanger 144a for heating outdoor air that heats the ventilation air supplied to the room through the air supply device 103 by using the heat of a heating medium ( Here, the supply air supplied to the room after being heat-exchanged in the heat exchanger 144a for outdoor air heating is indicated by SA3 in FIG. 1 ).

并且，在本实施例中，载热体回路104与载热体-制冷剂热交换器122连接，使在载热体-制冷剂热交换器122中被加热后的载热体依次向放热器141的放热器用热交换器141a、风扇对流式取暖器142的对流器用热交换器142a、地面取暖装置143的地面取暖用配管143a、室外空气加热用热交换装置144的室外空气加热用热交换器144a供给。具体而言，载热体回路104构成串联连接的单一的载热体回路，即，在载热体-制冷剂热交换器122中与制冷剂进行热交换而被加热后的载热体从载热体-制冷剂热交换器122的载热体出口依次通过放热器用热交换器141a、对流器用热交换器142a、地面取暖用配管143a、室外空气加热用热交换器144a后，通过与室外空气加热用热交换器144a的载热体出口连接的载热体循环泵145返回到载热体-制冷剂热交换器122的载热体入口。即，载热体回路104以从需要最高温的载热体的放热器用热交换器141a到可利用最低温的载热体的室外空气加热用热交换器144a的顺序进行连接。Moreover, in this embodiment, the heating medium circuit 104 is connected to the heating medium-refrigerant heat exchanger 122, so that the heating medium heated in the heating medium-refrigerant heat exchanger 122 sequentially releases heat to The radiator heat exchanger 141a of the radiator 141, the convector heat exchanger 142a of the fan convection heater 142, the floor heating pipe 143a of the floor heating device 143, and the outdoor air heating heat of the outdoor air heating heat exchange device 144. Exchange 144a supplies. Specifically, the heating medium circuit 104 constitutes a single heating medium circuit connected in series, that is, the heating medium heated by exchanging heat with the refrigerant in the heating medium-refrigerant heat exchanger 122 is transferred from the heating medium to the refrigerant. The heat carrier outlet of the heat body-refrigerant heat exchanger 122 passes through the radiator heat exchanger 141a, the convector heat exchanger 142a, the ground heating pipe 143a, and the outdoor air heating heat exchanger 144a, and then passes through the heat exchanger 144a with the outdoor air. The heating medium circulation pump 145 connected to the heating medium outlet of the air heating heat exchanger 144 a returns to the heating medium inlet of the heating medium-refrigerant heat exchanger 122 . That is, the heating medium circuit 104 is connected in order from the radiator heat exchanger 141a requiring the highest temperature heating medium to the outdoor air heating heat exchanger 144a using the lowest temperature heating medium.

载热体循环泵145连接在室外空气加热用热交换器144a的载热体出口与载热体-制冷剂热交换器122的载热体入口之间，由电动机等驱动机构驱动旋转，是使载热体在放热器用热交换器141a、对流器用热交换器142a、地面取暖用配管143a及室外空气加热用热交换器144a与载热体-制冷剂热交换器122之间循环的泵。The heating medium circulating pump 145 is connected between the heating medium outlet of the outdoor air heating heat exchanger 144a and the heating medium inlet of the heating medium-refrigerant heat exchanger 122, and is driven to rotate by a driving mechanism such as an electric motor to make the heating medium A pump that circulates heat between radiator heat exchanger 141a, convector heat exchanger 142a, floor heating pipe 143a, outdoor air heating heat exchanger 144a, and heating medium-refrigerant heat exchanger 122.

在此，作为在载热体回路104内流动的载热体可使用水和盐水。在作为载热体使用水时，具有构成载热体回路104的设备和配管都可比较廉价的优点。另外，在作为载热体使用盐水时，为了即使在室外空气温度低时，也使载热体不在室外空气加热用热交换装置144(具体而言为室外空气加热用热交换器144a)中冻结，希望具有在0℃以下也不冻结的特性。作为这种盐水例如有：氯化钙水溶液、氯化钠水溶液、氯化镁水溶液等。In this case, water and brine can be used as the heating medium flowing in the heating medium circuit 104 . When water is used as the heating medium, there is an advantage that both the equipment and piping constituting the heating medium circuit 104 can be relatively inexpensive. In addition, when salt water is used as the heating medium, the heating medium is prevented from freezing in the outdoor air heating heat exchange device 144 (specifically, the outdoor air heating heat exchanger 144 a ) even when the outdoor air temperature is low. , It is desirable to have the characteristics of not freezing below 0°C. Examples of such brine include calcium chloride aqueous solution, sodium chloride aqueous solution, magnesium chloride aqueous solution and the like.

(2)空调系统的动作(2) Operation of the air conditioning system

下面参照图1～图4对本实施例的空调系统101的动作进行说明。在此，图2是表示空调系统101的动作的温熵图。图3是表示空调系统101的动作的压焓图。图4是表示空调系统101的动作的空气线图。Next, the operation of the air conditioning system 101 of this embodiment will be described with reference to FIGS. 1 to 4 . Here, FIG. 2 is a temperature-entropy diagram showing the operation of the air conditioning system 101 . FIG. 3 is a pressure-enthalpy diagram showing the operation of the air conditioning system 101 . FIG. 4 is a pneumatic diagram showing the operation of the air conditioning system 101 .

首先，载热体循环泵145起动，使载热体在载热体回路104内循环。然后，使热源单元102的压缩机121起动。于是，吸入到压缩机121中的低压制冷剂(参照图1～图3中所示的点Rc)由压缩机121压缩后排出，成为高温高压的制冷剂(参照图1～图3中所示的点Ri)。该高温高压的制冷剂流入载热体-制冷剂热交换器122中对载热体进行加热，本身被冷却而成为低温高压的制冷剂(参照图1～图3中所示的点Ro3)。该在载热体-制冷剂热交换器122中因载热体的加热而被冷却的制冷剂由膨胀机构123减压后成为低温低压的气液两相状态的制冷剂(参照图1～图3中所示的点Re3)。该气液两相状态的制冷剂在热源侧热交换器124中由水或室外空气等热源加热后蒸发，成为低温低压的气态制冷剂(参照图1～图3中所示的点Rc)。并且，该低温低压的气态制冷剂重新吸入压缩机121中。First, the heating medium circulation pump 145 is started to circulate the heating medium in the heating medium circuit 104 . Then, the compressor 121 of the heat source unit 102 is started. Then, the low-pressure refrigerant sucked into the compressor 121 (see point Rc shown in FIGS. point Ri). The high-temperature and high-pressure refrigerant flows into the heating medium-refrigerant heat exchanger 122 to heat the heating medium, and is itself cooled to become a low-temperature and high-pressure refrigerant (see point Ro3 shown in FIGS. 1 to 3 ). The refrigerant cooled by the heating of the heating medium in the heating medium-refrigerant heat exchanger 122 is decompressed by the expansion mechanism 123 and becomes a low-temperature and low-pressure gas-liquid two-phase refrigerant (refer to FIGS. Point Re3) shown in 3). The refrigerant in the gas-liquid two-phase state is heated by a heat source such as water or outdoor air in the heat source side heat exchanger 124 and then evaporated to become a low-temperature and low-pressure gaseous refrigerant (see point Rc shown in FIGS. 1 to 3 ). And, the low-temperature and low-pressure gaseous refrigerant is sucked into the compressor 121 again.

在此，在载热体回路104内循环的载热体从载热体入口流入载热体-制冷剂热交换器122中(参照图1、图2及图4中所示的点Wi3)，在载热体-制冷剂热交换器122中，与由压缩机121压缩后排出的高温高压制冷剂进行热交换，从而被加热(参照图1、图2及图4中所示的点Wo)。并且，在载热体-制冷剂热交换器122中被加热后的高温载热体流入放热器141的放热器用热交换器141a中，将载热体的热量向室内放出(具体而言，对放热器用热交换器141a周围的室内空气进行加热)，载热体本身被冷却而温度降低(例如图2所示，从约70℃降到约65℃)。此时，室内空气(参照图4所示的点RA)在放热器用热交换器141a中被加热到图4所示的点SA1的状态。Here, the heating medium circulating in the heating medium circuit 104 flows into the heating medium-refrigerant heat exchanger 122 from the heating medium inlet (refer to point Wi3 shown in FIG. 1 , FIG. 2 and FIG. 4 ), In the heating medium-refrigerant heat exchanger 122, heat is exchanged with the high-temperature and high-pressure refrigerant compressed by the compressor 121 to be heated (see point Wo shown in FIG. 1 , FIG. 2 and FIG. 4 ). . And, the high-temperature heating medium heated in the heating medium-refrigerant heat exchanger 122 flows into the radiator heat exchanger 141a of the radiator 141, and the heat of the heating medium is released indoors (specifically, , heating the indoor air around the heat exchanger 141a for the heat radiator), the heat carrier itself is cooled and the temperature decreases (for example, as shown in FIG. 2, from about 70°C to about 65°C). At this time, room air (see point RA shown in FIG. 4 ) is heated to the state of point SA1 shown in FIG. 4 in radiator heat exchanger 141a.

接着，从放热器用热交换器141a流出的载热体流入风扇对流式取暖器142的对流器用热交换器142a中，将载热体的热量向室内放出(具体而言，对由对流器用风扇142b供给的室内空气进行加热)，载热体本身被冷却而温度降低(例如图2所示，从约65℃降到约55℃)。此时，室内空气(参照图1所示的点RA)通过对流器用热交换器142a作为供给空气SA1′(参照图1)向室内供给。Then, the heat carrier flowing out from the radiator heat exchanger 141a flows into the convector heat exchanger 142a of the fan convection heater 142, and the heat of the heat carrier is released indoors (specifically, for the fan used by the convector). The room air supplied by 142b is heated), and the heating medium itself is cooled and the temperature is lowered (for example, as shown in FIG. 2, from about 65° C. to about 55° C.). At this time, room air (see point RA shown in FIG. 1 ) is supplied into the room as supply air SA1' (see FIG. 1 ) through convector heat exchanger 142a.

接着，从对流器用热交换器142a流出的载热体流入地面取暖装置143的地面取暖用配管143a中，将载热体的热量向室内放出(具体而言，由地面取暖用配管143a对地面进行加热)，载热体本身被冷却而温度降低(例如图2所示，从约55℃降到约40℃)。Then, the heating medium flowing out from the convector heat exchanger 142a flows into the floor heating pipe 143a of the floor heating device 143, and the heat of the heating medium is released indoors (specifically, the ground is heated by the floor heating piping 143a). heating), the heat carrier itself is cooled and the temperature decreases (for example, as shown in Figure 2, it drops from about 55°C to about 40°C).

接着，从地面取暖用配管143a流出的载热体流入室外空气加热用热交换装置144的室外空气加热用热交换器144a中，利用载热体的热量对由供气装置103供给到室内的换气用空气进行加热，载热体本身被冷却而温度降低(例如图2所示，从约40℃降到约5℃)。此时，换气用空气(参照图4中所示的点OA，约-10℃)由室外空气加热用热交换器144a加热到图4所示的点SA3的状态(在图4中为约20℃)。另一方面，室内空气RA的温度通过放热器141、风扇对流式取暖器142及地面取暖装置143进行的取暖运转而被加热到约20℃(参照图4中所示的点RA)。因此，即使由该室外空气加热用热交换器144a加热后的换气用空气向室内供给而与室内空气RA混合，室内空气的温度也几乎不产生变化。Next, the heating medium flowing out from the floor heating pipe 143a flows into the outdoor air heating heat exchanger 144a of the outdoor air heating heat exchange device 144, and the heat of the heating medium is used to exchange the heat of the heating medium supplied to the room from the air supply device 103. The gas is heated with air, and the heating medium itself is cooled to lower its temperature (for example, as shown in Figure 2, from about 40°C to about 5°C). At this time, the air for ventilation (refer to point OA shown in FIG. 4, about -10° C.) is heated to the state of point SA3 shown in FIG. 4 (approximately -10° C. in FIG. 20°C). On the other hand, the temperature of the room air RA is heated to about 20° C. by the heating operation of the radiator 141 , the fan convection heater 142 , and the floor heater 143 (see point RA shown in FIG. 4 ). Therefore, even if the ventilation air heated by the outdoor air heating heat exchanger 144a is supplied indoors and mixed with the indoor air RA, the temperature of the indoor air hardly changes.

并且，从室外空气加热用热交换器144a流出的载热体通过载热体循环泵145重新流入载热体-制冷剂热交换器122中(参照图1、图2及图4中所示的点Wi3)。And, the heating medium flowing out from the outdoor air heating heat exchanger 144a flows into the heating medium-refrigerant heat exchanger 122 again through the heating medium circulation pump 145 (refer to the points shown in FIGS. 1 , 2 and 4 ). Wi3).

(3)空调系统的特征(3) Features of the air conditioning system

本实施例的空调系统101具有下述特征。The air conditioning system 101 of this embodiment has the following features.

(A)(A)

作为现有的空调系统901，如图5所示，包括：与本实施例的空调系统101相同的热源单元102、供气装置103、以及具有放热器141、风扇对流式取暖器142及载热体循环泵145的载热体回路904。在这种空调系统901中，由于载热体回路904不具有室外空气加热用热交换装置144，故在进行室内取暖时，换气用空气(图5中用OA表示)通过供气装置103直接向室内供给。因此，如图6所示，室内空气(参照图6中所示的点RA)和换气用空气(参照图6中所示的点OA)混合(参照图6中所示的点MA)，从而室内空气的温度变得比通过放热器141、风扇对流式取暖器142及地面取暖装置143进行的取暖运转而被加热的室内空气的温度低(在图4中为约12℃)。因此，为了进行室内的换气而向室内供给的换气用空气会导致产生冷风。As an existing air conditioning system 901, as shown in FIG. 5 , it includes: the same heat source unit 102 as the air conditioning system 101 of the present embodiment, an air supply device 103, and a heat radiator 141, a fan convection heater 142 and a heat sink. The heating medium circuit 904 of the heating medium circulation pump 145 . In this air conditioning system 901, since the heating medium circuit 904 does not have the heat exchange device 144 for heating outdoor air, the air for ventilation (indicated by OA in FIG. 5 ) passes through the air supply device 103 directly to Supply indoors. Therefore, as shown in FIG. 6, room air (refer to point RA shown in FIG. 6 ) and ventilation air (refer to point OA shown in FIG. 6 ) are mixed (refer to point MA shown in FIG. 6 ), Therefore, the temperature of the indoor air becomes lower than the temperature of the indoor air heated by the heating operation of the radiator 141, the fan convector 142, and the floor heating device 143 (approximately 12° C. in FIG. 4 ). Therefore, the air for ventilation supplied to the room for ventilation of the room causes cold wind to be generated.

但是，在本实施例的空调系统101中，具有室外空气加热用热交换装置144，因此，在进行室内取暖时，如图4所示，可在对通过供气装置103向室内供给的作为换气用空气的室外空气OA加热后，再将其作为供给空气SA3向室内供给，因此，可防止为了进行室内的换气而向室内供给的换气用空气引起冷风，可提高室内的舒适性。However, in the air-conditioning system 101 of this embodiment, there is the heat exchange device 144 for heating outdoor air. Therefore, when heating the room, as shown in FIG. The outside air OA of the air is heated and then supplied indoors as the supply air SA3. Therefore, it is possible to prevent the ventilation air supplied to the room for indoor ventilation from causing cold wind, and to improve indoor comfort.

(B)(B)

在现有的空调系统901中，由于载热体回路904不具有地面取暖装置143及室外空气加热用热交换装置144，因此，如图2、图3及图5所示，在载热体-制冷剂热交换器122中通过与制冷剂进行热交换而被加热的载热体在载热体回路104内循环，从点Wo的状态变为点Wi1的状态，并重新返回载热体-制冷剂热交换器122中。与此同时，如图2及图3所示，制冷剂在制冷剂回路120内循环，从压缩机121吸入侧的点Rc的状态依次经过与点Wo对应的点Ri的状态、与点Wi1对应的点Ro1的状态、点Re1的状态，并重新吸入到压缩机121中。在此，如图3所示，现有空调系统901中的热源单元102的COP(以蒸发侧为基准)是将点Rc→点Ri→点Ro1→点Re1→点Rc的制冷循环中的蒸发侧焓差Δh1的值与相当于压缩机121的消耗动力的焓差Δhc的值相除得到的值(＝Δh1/Δhc)。In the existing air conditioning system 901, since the heat carrier circuit 904 does not have the floor heating device 143 and the heat exchange device 144 for outdoor air heating, as shown in Fig. 2, Fig. 3 and Fig. 5, the heat carrier- The heating medium heated by exchanging heat with the refrigerant in the refrigerant heat exchanger 122 circulates in the heating medium circuit 104, changes from the state of point Wo to the state of point Wi1, and returns to the heating medium-refrigeration agent heat exchanger 122. At the same time, as shown in FIGS. 2 and 3 , the refrigerant circulates in the refrigerant circuit 120, passing through the state of point Ri corresponding to point Wo sequentially from the state of point Rc on the suction side of compressor 121, corresponding to point Wi1. The state of the point Ro1, the state of the point Re1, and re-inhaled into the compressor 121. Here, as shown in FIG. 3 , the COP (based on the evaporation side) of the heat source unit 102 in the conventional air conditioning system 901 is the point Rc → point Ri → point Ro1 → point Re1 → point Rc in the refrigeration cycle. The value obtained by dividing the value of the side enthalpy difference Δh1 by the value of the enthalpy difference Δhc corresponding to the power consumption of the compressor 121 (=Δh1/Δhc).

另一方面，在本实施例的空调系统101中，载热体回路104具有地面取暖装置143及室外空气加热用热交换装置144，且与载热体-制冷剂热交换器122连接，使在载热体-制冷剂热交换器122中加热的载热体依次向放热器141、风扇对流式取暖器142、地面取暖装置143、室外空气加热用热交换装置144供给，因此，如图1、图2及图3所示，在载热体-制冷剂热交换器122中通过与制冷剂进行热交换而被加热的载热体在载热体回路104内循环，从点Wo的状态变为点Wi3的状态，并重新返回载热体-制冷剂热交换器122中。与此同时，如图2及图3所示，制冷剂在制冷剂回路120内循环，从压缩机121吸入侧的点Rc的状态依次经过与点Wo对应的点Ri的状态、与点Wi3对应的点Ro3的状态、点Re3的状态，并重新吸入到压缩机121中。因此，在放热器141、风扇对流式取暖器142及地面取暖装置143中，可利用在载热体-制冷剂热交换器122中被加热后的高温载热体的热量，在室外空气加热用热交换装置144中，可利用在放热器141、风扇对流式取暖器142及地面取暖装置143中向室内放热而冷却后(参照图1及图2中所示的点Wi2)的载热体的热量。在此，由于通过供气装置103向室内供给的换气用空气(图1中用OA表示)的温度比室内空气(图1中用RA表示)低，因此，可利用在放热器141、风扇对流式取暖器142及地面取暖装置143中向室内放热而冷却后的载热体对其进行加热。并且，用于在室外空气加热用热交换装置144中对向室内供给的换气用空气进行加热的载热体在对换气用空气进行加热而进一步冷却后(参照图1及图2中所示的点Wi3)，返回到载热体-制冷剂热交换器122中。这样，在空调系统101中，将在放热器141、风扇对流式取暖器142及地面取暖装置143中放热而冷却的载热体向室外空气加热用热交换装置144供给，用于对向室内供给的换气用空气进行加热，因此，与空调系统901相比，可加大载热体-制冷剂热交换器122的出入口处的温差(即，点Wo状态下的载热体温度与点Wi3状态下的载热体温度的温差)。由此，如图3所示，由于本实施例的空调系统101中的热源单元102的COP(以蒸发侧为基准)是将点Rc→点Ri→点Ro3→点Re3→点Rc的制冷循环中的蒸发侧焓差Δh3的值与相当于压缩机121的消耗动力的焓差Δhc的值相除得到的值(＝Δh3/Δhc)，故与现有的不具有室外空气加热用热交换装置144的空调系统901相比，COP提高。尤其是在本实施例的空调系统101中，除室外空气加热用热交换装置144外还具有地面取暖装置143，因此，与现有的空调系统901相比，可进一步加大载热体-制冷剂热交换器122的出入口处的温差和COP。On the other hand, in the air conditioning system 101 of this embodiment, the heating medium circuit 104 has a floor heating device 143 and an outdoor air heating heat exchange device 144, and is connected to the heating medium-refrigerant heat exchanger 122, so that The heat carrier heated in the heat carrier-refrigerant heat exchanger 122 is supplied to the radiator 141, the fan convection heater 142, the floor heating device 143, and the heat exchange device 144 for outdoor air heating in sequence, so as shown in Figure 1 2 and 3, in the heat carrier-refrigerant heat exchanger 122, the heat carrier heated by exchanging heat with the refrigerant circulates in the heat carrier circuit 104, changing from the state at point Wo to It is the state of point Wi3, and returns to the heat medium-refrigerant heat exchanger 122 again. At the same time, as shown in FIGS. 2 and 3 , the refrigerant circulates in the refrigerant circuit 120, passing through the state of point Ri corresponding to point Wo sequentially from the state of point Rc on the suction side of compressor 121, corresponding to point Wi3. The state of the point Ro3, the state of the point Re3, and re-inhaled into the compressor 121. Therefore, in the radiator 141, the fan convection heater 142, and the floor heating device 143, the heat of the high-temperature heat carrier heated in the heat carrier-refrigerant heat exchanger 122 can be used to heat the outdoor air. In the heat exchanging device 144, it is possible to use the load after cooling (referring to point Wi2 shown in Fig. The heat of a hot body. Here, since the temperature of the ventilation air (shown by OA in FIG. 1 ) supplied to the room by the air supply device 103 is lower than that of the room air (shown by RA in FIG. 1 ), it can be used in the radiator 141, The fan convection heater 142 and the floor heating device 143 radiate heat into the room and the cooled heat carrier heats it. And, the heating medium used for heating the ventilation air supplied to the room in the heat exchange device 144 for heating outdoor air heats the ventilation air and further cools it (see FIG. 1 and FIG. 2 ). Shown point Wi3), return to the heating medium-refrigerant heat exchanger 122. In this way, in the air-conditioning system 101, the heating medium cooled by the radiator 141, the fan convection heater 142, and the floor heating device 143 is supplied to the heat exchange device 144 for heating outdoor air for opposing The ventilation air supplied indoors is heated. Therefore, compared with the air conditioning system 901, the temperature difference at the inlet and outlet of the heat carrier-refrigerant heat exchanger 122 can be increased (that is, the temperature of the heat carrier in the point Wo state and The temperature difference of the heating medium temperature at point Wi3 state). Thus, as shown in FIG. 3 , since the COP (based on the evaporation side) of the heat source unit 102 in the air-conditioning system 101 of the present embodiment is a refrigeration cycle from point Rc→point Ri→point Ro3→point Re3→point Rc The value obtained by dividing the value of the evaporation side enthalpy difference Δh3 by the value of the enthalpy difference Δhc corresponding to the power consumption of the compressor 121 (= Δh3/Δhc), so it is different from the existing heat exchange device for heating outdoor air. Compared with 144 air conditioning system 901, the COP is improved. Especially in the air conditioning system 101 of this embodiment, in addition to the heat exchange device 144 for outdoor air heating, there is also a floor heating device 143. The temperature difference at the inlet and outlet of the agent heat exchanger 122 and the COP.

在本实施例的空调系统101中，在作为在载热体回路104内流动的载热体使用水时，可廉价地构成载热体回路104。另外，在作为在载热体回路104内流动的载热体使用在0℃以下不冻结的盐水时，即使在室外空气温度低时，载热体也不会在室外空气加热用热交换装置144中冻结，可提高使用室外空气加热用热交换装置144对通过供气装置103向室内供给的换气用空气进行加热时的可靠性。In the air conditioning system 101 of this embodiment, when water is used as the heating medium flowing in the heating medium circuit 104, the heating medium circuit 104 can be configured at low cost. In addition, when brine that does not freeze below 0° C. is used as the heating medium flowing in the heating medium circuit 104 , the heating medium will not flow in the outdoor air heating heat exchange device 144 even when the outdoor air temperature is low. Freezing in the middle can improve the reliability when the outdoor air heating heat exchange device 144 is used to heat the ventilation air supplied to the room through the air supply device 103 .

Heat carrier circuit. For example, in the heating medium circuit 104 shown in FIG. 7 without the fan convection heater 142, bypass loads can also be provided for the radiator 141, the floor heating device 143, and the heat exchange device 144 for outdoor air heating.

Accordingly, the heating medium can be supplied to only a part of the heat radiator 141 , the floor heating device 143 , and the heat exchange device 144 for heating outdoor air as necessary.

并且，在这些旁通载热体回路151、153、154中分别设置有作为载热体流量调节机构的电磁阀151a、电动阀153a、电磁阀154a。由此，旁通载热体回路151、154可根据需要切断在各旁通载热体回路151、154中流动的载热体，可调节向放热器141及室外空气加热用热交换装置144供给的载热体的流量。另外，旁通载热体回路153可调节在旁通载热体回路153中流动的载热体的流量，可高精度地调节向地面取暖装置143供给的载热体的流量。Furthermore, in these bypass heating medium circuits 151, 153, and 154, electromagnetic valve 151a, electric valve 153a, and electromagnetic valve 154a are respectively provided as heating medium flow rate adjustment means. As a result, the bypass heating medium circuits 151 and 154 can cut off the heating medium flowing in each bypass heating medium circuit 151 and 154 as required, and the heating medium flowing to the heat radiator 141 and the outdoor air heating heat exchange device 144 can be adjusted.

In addition, the bypass heating medium circuit 153 can adjust the flow rate of the heating medium flowing in the bypass heating medium circuit 153 , and can adjust the flow rate of the heating medium supplied to the floor heating device 143 with high precision.

In addition, the type of valve provided in the bypass heating medium circuit can be selected according to the flow rate adjustment accuracy of the heating medium required by each bypass heating medium circuit, and the like.

(5)变形例2(5) Modification 2

在上述空调系统101中，放热器141、风扇对流式取暖器142、地面取暖装置143及室外空气加热用热交换装置144中的一部分也可不通过载热体回路104地利用在制冷剂回路120内流动的制冷剂。例如，在图8所示的不具有风扇对流式取暖器142的空调系统101中，地面取暖装置143及室外空气加热用热交换装置144通过在载热体回路104内循环的载热体来利用在热源单元102的制冷剂回路120内流动的制冷剂的热量，但对于放热器141，可以使由压缩机121压缩后排出的高温高压制冷剂流入放热器141的放热器用热交换器141a中，将制冷剂的热量直接向室内放出。由此，可实现载热体回路104的简单化。In the above-mentioned air conditioning system 101, some of the radiator 141, the fan convection heater 142, the floor heating device 143, and the heat exchange device 144 for heating outdoor air may be used in the refrigerant circuit 120 without passing through the heating medium circuit 104.

In the device 144a, the heat of the refrigerant is used. In addition, in the air conditioning system 101 of this modified example, the bypass heating medium circuit in the modified example 1 may be provided.

For example, in the air conditioning system 101 shown in FIG. 9 having the same bypass heating medium circuits 151, 153, and 154 as Modification 1, a heating medium storage tank 161 may be provided on the suction side of the heating medium circulation pump 145. . This prevents problems such as damage to equipment constituting the heating medium circuit 104 due to volume expansion due to temperature changes of the heating medium circulating in the heating medium circuit 104 . In addition, since the amount of heating medium held in the heating medium circuit 104 increases, the heat capacity of the entire heating medium circuit 104 increases, and the heat supplied to the radiator 141, the floor heating device 143, and the heat exchange device 144 for outdoor air heating The temperature of the heating medium and the temperature of the heating medium returning to the heating medium-refrigerant heat exchanger 122 are stabilized, so that the controllability of the heat source unit 102 and the heating medium circuit 104 can be improved.

Here, the divided heating medium circuits 104a, 104b, and 104c have heating medium circulation pumps 145a, 145b, and 145c, respectively. Accordingly, the heating medium can be supplied to only a part of the heat radiator 141 , the floor heating device 143 , and the heat exchange device 144 for heating outdoor air as necessary.

在上述变形例5的空调系统101中，载热体回路104分别与放热器141、地面取暖装置143及室外空气加热用热交换装置144对应地被分割成分割载热体回路104a、104b、104c，载热体-制冷剂热交换器122也被分割成与分割载热体回路104a、104b、104c对应的分割载热体-制冷剂热交换器122a、122b、122c，但并不限定于此，例如在图12所示的不具有风扇对流式取暖器142的空调系统101中，也可将载热体回路104分割成包含放热器141专用的第一载热体循环泵145a在内的第一分割载热体回路104a、以及包含地面取暖装置143和室外空气加热用热交换装置144共用的第二载热体循环泵145d在内的第二分割载热体回路104d，且将载热体-制冷剂热交换器122分割成放热器141专用的第一分割载热体-制冷剂热交换器122a、以及地面取暖装置143和室外空气加热用热交换装置144共用的第二分割载热体-制冷剂热交换器122d。In the air conditioning system 101 of Modification 5 above, the heating medium circuit 104 is divided into divided heating medium circuits 104a, 104b, 104c, the heating medium-refrigerant heat exchanger 122 is also divided into divided heating medium-refrigerant heat exchangers 122a, 122b, 122c corresponding to the divided heating medium circuits 104a, 104b, 104c, but not limited to Here, for example, in the air conditioning system 101 that does not have the fan convection heater 142 shown in FIG. The first divided heating medium circuit 104a, and the second divided heating medium circuit 104d including the second heating medium circulation pump 145d shared by the ground heating device 143 and the outdoor air heating heat exchange device 144, and the heating medium -The refrigerant heat exchanger 122 is divided into the first divided heat carrier dedicated to the heat radiator 141-refrigerant heat exchanger 122a, and the second divided heat carrier shared by the floor heating device 143 and the heat exchange device 144 for outdoor air heating Body-to-refrigerant heat exchanger 122d.

(10)变形例7(10) Modification 7

在上述变形例5、6的空调系统101中，制冷剂回路120还可具有对分割载热体-制冷剂热交换器进行旁通的至少一个旁通制冷剂回路。例如，在图13所示的具有与变形例5相同的分割载热体-制冷剂热交换器122a、122b、122c的制冷剂回路120中，可以与第一分割载热体-制冷剂热交换器122a对应地设置旁通制冷剂回路171。由此，可根据需要仅向分割载热体-制冷剂热交换器122b、122c供给制冷剂。In the air-conditioning system 101 according to the modification examples 5 and 6, the refrigerant circuit 120 may further include at least one bypass refrigerant circuit that bypasses the divided heating medium-refrigerant heat exchanger. For example, in the refrigerant circuit 120 shown in FIG. 13 having the same divided heating medium-refrigerant heat exchangers 122a, 122b, and 122c as Modification 5, it is possible to exchange heat with the first divided heating medium-refrigerant. The refrigerant 122a is correspondingly provided with a bypass refrigerant circuit 171 . As a result, the refrigerant can be supplied only to the divided heating medium-refrigerant heat exchangers 122b and 122c as necessary.

并且，在旁通制冷剂回路171中设置有作为载热体流量调节机构的电磁阀171a。由此，旁通制冷剂回路171可根据需要切断在各旁通载热体回路171中流动的载热体，可调节向第一分割载热体-制冷剂热交换器122a供给的制冷剂的流量。Furthermore, in the bypass refrigerant circuit 171, a solenoid valve 171a as a heating medium flow rate adjustment mechanism is provided. As a result, the bypass refrigerant circuit 171 can cut off the heating medium flowing in each bypass heating medium circuit 171 as necessary, and the amount of refrigerant supplied to the first divided heating medium-refrigerant heat exchanger 122a can be adjusted. flow.

另外，如上所述，旁通制冷剂回路可以仅与第一分割载热体-制冷剂热交换器122a对应地设置，也可分别与分割载热体-制冷剂热交换器122a、122b、122c对应地设置，或者也可设置成对分割载热体-制冷剂热交换器122a、122b、122c中的几个集中起来进行旁通的形态。另外，对于设在旁通制冷剂回路中的阀的种类，可根据各旁通制冷剂回路所需的载热体的流量调节精度等进行选择，例如也可取代电磁阀而使用电动阀，此时可高精度地调节向旁通制冷剂回路供给的制冷剂的流量。In addition, as described above, the bypass refrigerant circuit may be provided corresponding to only the first divided heating medium-refrigerant heat exchanger 122a, or may be provided separately to the divided heating medium-refrigerant heat exchangers 122a, 122b, and 122c. It is provided correspondingly, or it may also be provided in a form in which several of the divided heating medium-refrigerant heat exchangers 122a, 122b, and 122c are collectively bypassed. In addition, the type of valves installed in the bypass refrigerant circuits can be selected according to the flow rate adjustment accuracy of the heating medium required by each bypass refrigerant circuit. For example, an electric valve can also be used instead of a solenoid valve. At this time, the flow rate of the refrigerant supplied to the bypass refrigerant circuit can be adjusted with high precision.

(11)变形例8(11) Modification 8

在上述变形例5～7的空调系统101中，放热器141、风扇对流式取暖器142、地面取暖装置143及室外空气加热用热交换装置144中的一部分也可不通过载热体回路104地利用在制冷剂回路120内流动的制冷剂。例如，在图14所示的与变形例5相同的不具有风扇对流式取暖器142的空调系统101中，地面取暖装置143及室外空气加热用热交换装置144通过在分割载热体回路104b、104c内循环的载热体来利用在热源单元102的制冷剂回路120内流动的制冷剂的热量，但对于放热器141，可以使由压缩机121压缩后排出的高温高压制冷剂流入放热器141的放热器用热交换器141a中，将制冷剂的热量直接向室内放出。由此，可实现载热体回路104的简单化。In the air conditioning system 101 of the above modification examples 5 to 7, part of the radiator 141, the fan convection heater 142, the floor heating device 143, and the heat exchange device 144 for heating outdoor air may not pass through the heating medium circuit 104. Refrigerant flowing in the refrigerant circuit 120 is used. For example, in the air conditioning system 101 shown in FIG. 14 that does not have the fan convection heater 142 the same as Modification 5, the floor heating device 143 and the heat exchange device 144 for heating outdoor air pass through the divided heating medium circuit 104b, The heat carrier circulating in 104c utilizes the heat of the refrigerant flowing in the refrigerant circuit 120 of the heat source unit 102, but for the radiator 141, the high-temperature and high-pressure refrigerant discharged after being compressed by the compressor 121 can flow into the heat release In the radiator heat exchanger 141a of the radiator 141, the heat of the refrigerant is released directly into the room. This enables simplification of the heating medium circuit 104 .

另外，即使对于放热器141以外的地面取暖装置143和室外空气加热用热交换装置144，也可使在制冷剂回路120内流动的制冷剂流入地面取暖用配管143a和室外空气加热用热交换器144a中而利用制冷剂的热量。In addition, even for the floor heating device 143 other than the radiator 141 and the heat exchange device 144 for outdoor air heating, the refrigerant flowing in the refrigerant circuit 120 can flow into the pipe 143a for floor heating and exchange heat for outdoor air heating. In the device 144a, the heat of the refrigerant is used.

(12)变形例9(12) Modification 9

在上述变形例5～7的空调系统101中，也可在载热体回路104中设置载热体储存箱。例如，在图15所示的具有与变形例5相同的分割载热体回路104a、104b、104c的空调系统101中，也可在载热体循环泵145a、145b、145c的吸入侧分别设置载热体储存箱161a、161b、161c。由此，可防止载热体回路104内循环的载热体因温度变化而体积膨胀造成分割载热体回路104a、104b、104c的设备破损等不良状况。另外，由于分割载热体回路104a、104b、104c保有的载热体量增加，从而各分割载热体回路104a、104b、104c的热容量增大，向放热器141、地面取暖装置143及室外空气加热用热交换装置144供给的载热体的温度和返回到分割载热体-制冷剂热交换器122a、122b、122c中的载热体的温度稳定，因此，可改善热源单元102及分割载热体回路104a、104b、104c的控制性。In the air-conditioning system 101 of the modification examples 5 to 7 described above, a heating medium storage tank may be provided in the heating medium circuit 104 . For example, in the air conditioning system 101 shown in FIG. 15 having the same divided heating medium circuits 104a, 104b, and 104c as Modification 5, it is also possible to install heat transfer fluids on the suction sides of the heating medium circulation pumps 145a, 145b, and 145c, respectively. Body storage boxes 161a, 161b, 161c. Thereby, failures such as damage to equipment dividing the heating medium circuits 104a, 104b, and 104c caused by volume expansion of the heating medium circulating in the heating medium circuit 104 due to temperature changes can be prevented. In addition, since the amount of heating medium retained by the divided heating medium circuits 104a, 104b, and 104c increases, the heat capacity of each divided heating medium circuit 104a, 104b, and 104c increases, and the heat transfer to the heat radiator 141, the floor heating device 143, and the outdoor space The temperature of the heat medium supplied by the heat exchange device 144 for air heating and the temperature of the heat medium returned to the divided heat medium-refrigerant heat exchangers 122a, 122b, 122c are stabilized, so that the heat source unit 102 and the divided heat exchanger can be improved. Controllability of heating medium circuits 104a, 104b, 104c.

(13)变形例10(13) Modification 10

在上述实施例及变形例的空调系统101中，具有室外空气加热用热交换装置144，因此，可防止为了进行室内的换气而向室内供给的换气用空气引起冷风，可提高室内的舒适性。但是，在换气用空气的绝对湿度比室内空气的绝对湿度低时，由于换气用空气的供给有时会使室内变得干燥。因此，在本变形例中，在上述实施例及变形例的空调系统101的基础上，还设置有对由室外空气加热用热交换装置144加热后向室内供给的换气用空气进行加湿的加湿装置。In the air conditioning system 101 of the above-mentioned embodiment and modified example, since the heat exchange device 144 for heating the outdoor air is provided, the ventilation air supplied to the room for indoor ventilation can be prevented from causing cold wind, and the comfort of the room can be improved. sex. However, when the absolute humidity of the ventilation air is lower than the absolute humidity of the room air, the room may become dry due to the supply of the ventilation air. Therefore, in this modified example, in addition to the air conditioning system 101 of the above-mentioned embodiments and modified examples, a humidifier for humidifying the ventilation air supplied to the room after being heated by the heat exchange device 144 for heating outdoor air is provided. device.

例如，在图16所示的与图1相同的空调系统101中，设置有：具有对由室外空气加热用热交换装置144加热后向室内供给的换气用空气喷水的喷雾嘴182a的加湿装置182、以及向加湿装置182的喷雾嘴182a供水的供水配管181。For example, in the same air conditioning system 101 as shown in FIG. 1 shown in FIG. 16 , there is provided: a humidifier with a spray nozzle 182a that sprays water on the ventilation air supplied to the room after being heated by the heat exchange device 144 for heating outdoor air. The device 182 and the water supply pipe 181 that supplies water to the spray nozzle 182 a of the humidifier 182 .

此时，在室外空气加热用热交换装置144中与载热体进行热交换而被加热的换气用空气(图16中用SA3表示)在向室内供给时，先导入到加湿装置182中，由从加湿装置182的喷雾嘴182a喷出的水加湿后再向室内供给(图16中用SA3′表示)。由此，在本变形例的空调系统101中，可进行换气用空气的加湿，因此，即使在换气用空气的绝对湿度比室内空气的绝对湿度低时，通过向室内供给换气用空气也可防止室内变得干燥。At this time, the ventilation air (indicated by SA3 in FIG. 16 ) heated by exchanging heat with the heating medium in the heat exchange device 144 for heating outdoor air is first introduced into the humidifier 182 when it is supplied into the room. The water sprayed from the spray nozzle 182a of the humidifier 182 is supplied into the room after being humidified (indicated by SA3' in FIG. 16). As a result, in the air conditioning system 101 of this modified example, it is possible to humidify the ventilation air. Therefore, even when the absolute humidity of the ventilation air is lower than the absolute humidity of the room air, by supplying the ventilation air into the room, It also prevents the interior from becoming dry.

另外，由于从喷雾嘴182a喷出的水的蒸发，由加湿装置182加湿后的换气用空气的温度比在室外空气加热用热交换装置144中加热后的温度低。但是，在本变形例的空调系统101中，通过预先考虑到加湿装置182中的水的蒸发而增加室外空气加热用热交换装置144中的换气用空气的加热量，从而例如图17所示，将换气用空气(图17中用SA3表示)通过室外空气加热用热交换装置144加热到比没有设置加湿装置182的图1的空调系统中的换气用空气(图4中用SA3表示)的温度(在图4中为约20℃)高的温度(在图17中为约30℃)，从而即使换气用空气的温度因加湿装置182中的水的蒸发而变低，也可使向室内供给的换气用空气(图17中用SA3′表示)的温度(在图17中为约20℃)接近室内空气(图17中用RA表示)的温度。并且，换气用空气SA3′的绝对湿度也基本与室内空气RA的绝对湿度(在图17中相当于相对湿度的50％)相同。因此，在本变形例的空调系统101中，可在通过室外空气加热用热交换装置144及加湿装置182将与室内空气相比低温、低湿度的换气用空气加热及加湿到与室内空气相同的温度及湿度状态后，再向室内供给，从而可进一步提高室内的舒适性。In addition, the temperature of the ventilation air humidified by the humidifier 182 is lower than that heated by the outdoor air heating heat exchange device 144 due to the evaporation of water sprayed from the spray nozzle 182a. However, in the air conditioning system 101 of this modified example, the heating amount of the ventilation air in the outdoor air heating heat exchange device 144 is increased by considering the evaporation of water in the humidifier 182 in advance, so that, for example, as shown in FIG. 17 , the air for ventilation (shown by SA3 in FIG. 17 ) is heated by the heat exchange device 144 for outdoor air heating to a temperature higher than that of the air for ventilation (shown by SA3 in FIG. 4 ) in the air conditioning system of FIG. 1 without humidifier 182. ) temperature (approximately 20°C in FIG. 4) high temperature (approximately 30°C in FIG. The temperature (approximately 20° C. in FIG. 17 ) of the ventilation air (indicated by SA3' in FIG. 17 ) supplied to the room is brought close to the temperature of the indoor air (indicated by RA in FIG. 17 ). In addition, the absolute humidity of the ventilation air SA3' is almost the same as the absolute humidity of the room air RA (corresponding to 50% of the relative humidity in FIG. 17 ). Therefore, in the air-conditioning system 101 of this modified example, the air for ventilation, which is lower in temperature and lower in humidity than the indoor air, can be heated and humidified to the same temperature as the indoor air by the outdoor air heating heat exchange device 144 and the humidifier 182. After the temperature and humidity conditions are determined, it is supplied to the room, which can further improve the comfort of the room.

另外，作为加湿装置也可取代喷雾嘴而使用空气洗净器。In addition, an air washer may be used as a humidifier instead of a spray nozzle.

(14)变形例11(14) Modification 11

在上述变形例10的空调系统101中，对由室外空气加热用热交换装置144加热后向室内供给的换气用空气进行加湿的加湿装置采用使用了喷雾嘴或空气洗净器的装置，但并不限定于此，也可采用使用了具有透过水蒸气的性质的透湿膜的装置。例如，在图18所示的不具有风扇对流式取暖器142的空调系统101中，设置有：包括具有多个管状透湿膜的透湿膜单元183a的加湿装置183；以及向加湿装置183的透湿膜单元183a供水的供水配管181。在此，在透湿膜单元183a中设置有供由室外空气加热用热交换装置144加热后向室内供给的换气用空气经过透湿膜外部的流路。另外，向透湿膜内部导入向透湿膜单元183a供给的水，使向透湿膜供给的水通过透湿膜与换气用空气接触，从而可对换气用空气进行加湿。作为透湿膜可使用聚四氟乙烯(PTFE)等。In the air conditioning system 101 of Modification 10, the humidifier for humidifying the ventilation air heated by the heat exchange device 144 for heating outdoor air and supplied to the room is a humidifier using a spray nozzle or an air washer. The present invention is not limited thereto, and a device using a moisture-permeable film having a property of permeating water vapor may also be used. For example, in the air conditioning system 101 shown in FIG. 18 that does not have the fan convector 142, there are provided: a humidifying device 183 including a moisture-permeable membrane unit 183a having a plurality of tubular moisture-permeable membranes; The water supply pipe 181 that supplies water to the moisture permeable membrane unit 183a. Here, the moisture-permeable membrane unit 183a is provided with a flow path through which the ventilation air heated by the outdoor air heating heat exchange device 144 and supplied to the room passes through the outside of the moisture-permeable membrane. Also, the water supplied to the moisture-permeable membrane unit 183a is introduced into the moisture-permeable membrane, and the water supplied to the moisture-permeable membrane contacts the ventilation air through the moisture-permeable membrane, thereby humidifying the ventilation air. As the moisture-permeable membrane, polytetrafluoroethylene (PTFE) or the like can be used.

此时，使向加湿装置183的透湿膜单元183a的透湿膜供给的水通过透湿膜与换气用空气接触，从而可对换气用空气进行加湿，因此，与变形例10相同，即使在换气用空气的绝对湿度比室内空气的绝对湿度低时，也可防止因向室内供给换气用空气导致室内变得干燥。At this time, the water supplied to the moisture-permeable membrane of the moisture-permeable membrane unit 183a of the humidifier 183 is brought into contact with the ventilation air through the moisture-permeable membrane to humidify the ventilation air. Therefore, as in Modification 10, Even when the absolute humidity of the ventilation air is lower than the absolute humidity of the room air, it is possible to prevent the room from drying out due to the supply of the ventilation air into the room.

并且，在本变形例的空调系统101中，通过预先考虑到加湿装置183中的水的蒸发而增加室外空气加热用热交换装置144中的换气用空气的加热量，从而与变形例10相同，可在将与室内空气相比低温、低湿度的换气用空气加热及加湿到与室内空气相同的温度及湿度状态后，再向室内供给，可进一步提高室内的舒适性。In addition, in the air conditioning system 101 of this modified example, the heating amount of the ventilation air in the outdoor air heating heat exchange device 144 is increased by taking into account the evaporation of water in the humidifier 183 in advance, which is the same as the tenth modified example. , It can heat and humidify the ventilation air with lower temperature and lower humidity than the indoor air to the same temperature and humidity state as the indoor air, and then supply it to the room, which can further improve the comfort of the room.

(15)变形例12(15) Modification 12

在上述变形例10、11的空调系统101中，采用了通过供水配管181向加湿装置供水的所谓供水式加湿装置，但并不限定于此，也可采用使用了既可吸收水分又可通过加热使吸收的水分脱离的吸湿液的装置。In the air-conditioning system 101 of Modifications 10 and 11 above, a so-called water supply type humidifier that supplies water to the humidifier through the water supply pipe 181 is used. A device for absorbing hygroscopic fluids that releases absorbed moisture.

例如，在图19所示的不具有风扇对流式取暖器142的空调系统101中，设置有加湿装置184，该加湿装置184包括：具有多个管状透湿膜的第一及第二透湿膜单元184a、184b；以及使吸湿液在第一透湿膜单元184a与第二透湿膜单元184b之间循环的吸湿液循环泵184c。For example, in the air conditioning system 101 shown in FIG. 19 without the fan convection heater 142, a humidifying device 184 is provided, and the humidifying device 184 includes first and second moisture-permeable membranes having a plurality of tubular moisture-permeable membranes. units 184a, 184b; and a moisture-absorbing liquid circulation pump 184c that circulates the moisture-absorbing liquid between the first moisture-permeable membrane unit 184a and the second moisture-permeable membrane unit 184b.

具体而言，在第一透湿膜单元184a中设置有供由室外空气加热用热交换装置144加热后向室内供给的换气用空气经过透湿膜外部的流路。另外，向第一透湿膜单元184a的透湿膜内部导入利用吸湿液循环泵184c进行循环的吸湿液，使向透湿膜供给的吸湿液通过透湿膜与换气用空气接触，利用换气用空气对吸收了水分的吸湿液进行加热，使水分向换气用空气中脱离，从而可对换气用空气进行加湿。在第二透湿膜单元184b中设置有供从室内向室外排出的排出空气经过透湿膜外部的流路。另外，向第二透湿膜单元184b的透湿膜内部导入利用吸湿液循环泵184c进行循环的吸湿液，使向透湿膜供给的吸湿液通过透湿膜与排出空气接触，可使吸湿液吸收排出空气中含有的水分。作为透湿膜可使用聚四氟乙烯(PTFE)等。另外，作为吸湿液可使用氯化锂水溶液等。Specifically, the first moisture-permeable membrane unit 184a is provided with a flow path through which the ventilation air heated by the outdoor air heating heat exchange device 144 and supplied to the room passes through the outside of the moisture-permeable membrane. In addition, the moisture-absorbing liquid circulated by the moisture-absorbing liquid circulation pump 184c is introduced into the moisture-permeable membrane of the first moisture-permeable membrane unit 184a, and the moisture-absorbing liquid supplied to the moisture-permeable membrane is brought into contact with the air for ventilation through the moisture-permeable membrane. The air for air heats the moisture-absorbing liquid that has absorbed moisture, and desorbs the moisture into the air for ventilation, thereby humidifying the air for ventilation. The second moisture-permeable membrane unit 184b is provided with a flow path through which exhaust air discharged from the indoor to the outdoor passes through the outside of the moisture-permeable membrane. In addition, the moisture-absorbing liquid circulated by the moisture-absorbing liquid circulation pump 184c is introduced into the moisture-permeable membrane of the second moisture-permeable membrane unit 184b. Absorbs moisture contained in exhaust air. As the moisture-permeable membrane, polytetrafluoroethylene (PTFE) or the like can be used. Moreover, lithium chloride aqueous solution etc. can be used as a moisture absorption liquid.

并且，在该加湿装置184中，进行通过吸湿液循环泵184c使吸湿液依次经由第二透湿膜单元184b、第一透湿膜单元184a进行循环的运转。在该状态下，在排出空气通过第二透湿膜单元184b时，通过第二透湿膜单元184b的透湿膜使吸附液吸收排出空气中含有的水分。该含有水分的吸湿液向第一透湿膜单元184a输送。接着，在由室外空气加热用热交换装置144加热后的换气用空气通过第一透湿膜单元184a时，通过透湿膜对从第二透湿膜单元184b输送到第一透湿膜单元184a的吸湿液进行加热，从而通过吸湿膜使水分从该被加热的吸湿液中脱离到换气用空气中，因而可对换气用空气进行加湿后向室内供给。And in this humidifier 184, the operation which circulates a moisture-absorbing liquid through the 2nd moisture-permeable membrane unit 184b and the 1st moisture-permeable membrane unit 184a sequentially by the moisture-absorbing liquid circulation pump 184c is performed. In this state, when the exhaust air passes through the second moisture-permeable membrane unit 184b, the moisture contained in the exhaust air is absorbed by the adsorbent through the moisture-permeable membrane of the second moisture-permeable membrane unit 184b. The moisture-absorbing liquid containing moisture is sent to the first moisture-permeable membrane unit 184a. Next, when the ventilation air heated by the heat exchange device 144 for heating outdoor air passes through the first moisture-permeable membrane unit 184a, it is sent from the second moisture-permeable membrane unit 184b to the first moisture-permeable membrane unit through the pair of moisture-permeable membranes. The hygroscopic liquid at 184a is heated, and moisture is desorbed from the heated hygroscopic liquid into the ventilation air through the hygroscopic membrane, so that the ventilation air can be humidified and supplied into the room.

这样，在本变形例的空调系统101中，由于具有使用了吸湿液的加湿装置184，故利用换气用空气对吸收了水分的吸湿液进行加热，使水分脱离到换气用空气中，从而可对换气用空气进行加湿。另外，在空调系统101中，作为吸湿液吸收的水分利用从室内向室外排出的排出空气中含有的水分，因此，不需向加湿装置184供水即可进行换气用空气的加湿。In this way, in the air conditioning system 101 of this modified example, since the humidifier 184 using the moisture-absorbing liquid is provided, the moisture-absorbing liquid that has absorbed moisture is heated by the ventilation air to detach the moisture into the ventilation air, thereby Air for ventilation can be humidified. In addition, in the air conditioning system 101, the moisture absorbed as the hygroscopic liquid utilizes the moisture contained in the exhaust air discharged from the indoor to the outdoor, and therefore, the humidifying air for ventilation can be humidified without supplying water to the humidifier 184 .

另外，如图20所示，为了扩大加湿装置184的湿度调节范围等，也可使从室内向室外排出的排出空气(在图20的第二透湿膜单元184b的左侧用RA表示)和与换气用空气不同的室外空气(在图20的第二透湿膜单元184b的左侧用OA表示)的混合空气经过第二透湿膜单元184b，通过第二透湿膜单元184b的透湿膜使吸湿液吸收水分，该水分在第一透湿膜单元184a中通过透湿膜从吸湿液脱离到换气用空气中。In addition, as shown in FIG. 20, in order to expand the humidity adjustment range of the humidifier 184, etc., the exhaust air (indicated by RA on the left side of the second moisture-permeable membrane unit 184b in FIG. The mixed air of outdoor air (indicated by OA on the left side of the second moisture-permeable membrane unit 184b in FIG. The wet film allows the moisture-absorbing liquid to absorb moisture, and the moisture passes through the moisture-permeable film in the first moisture-permeable film unit 184a and escapes from the moisture-absorbing liquid into the ventilation air.

另外，在本变形例中，使用了吸湿液的加湿装置184通过具有透湿膜的透湿膜单元184a、184b进行吸湿液和空气之间的水分交换，但并不限定于此，也可使吸湿液和空气直接接触。另外，在图20所示的加湿装置184中，使从室内向室外排出的排出空气及与换气用空气不同的室外空气双方经过第二透湿膜单元184b，但也可仅使与换气用空气不同的室外空气经过。In addition, in this modified example, the humidifier 184 using the moisture-absorbing fluid performs moisture exchange between the moisture-absorbing fluid and the air through the moisture-permeable membrane units 184a and 184b having moisture-permeable membranes, but it is not limited to this, and may be used The moisture-absorbing liquid is in direct contact with the air. In addition, in the humidifier 184 shown in FIG. 20, both the exhaust air discharged from the room to the outside and the outdoor air different from the ventilation air are passed through the second moisture-permeable membrane unit 184b, but only the ventilation air may be used to pass the second moisture-permeable membrane unit 184b. I pass with the outdoor air different from the air.

(16)变形例13(16) Modification 13

在上述变形例12的空调系统101中，作为不需供水即可加湿的加湿装置采用使用了可吸收水分、且可通过加热使吸收的水分脱离的吸湿液的装置，但也可采用使用了可吸附水分、且可通过加热使吸附的水分脱离的吸附剂的装置。In the air conditioning system 101 of Modification 12 described above, a humidifier using a hygroscopic liquid that absorbs moisture and desorbs the absorbed moisture by heating is used as a humidifier that can humidify without supplying water. A device that absorbs moisture and desorbs the adsorbed moisture by heating.

例如，在图21所示的不具有风扇对流式取暖器142的空调系统101中，设置有加湿装置185，该加湿装置185具有担载有吸附剂的干燥剂转动体185a。For example, in the air conditioning system 101 shown in FIG. 21 that does not have the fan convector 142, a humidifier 185 having a desiccant rotor 185a carrying an adsorbent is provided.

具体而言，在加湿装置185中设置有供由室外空气加热用热交换装置144加热后向室内供给的换气用空气经过干燥剂转动体185a的一部分的流路。另外，在干燥剂转动体185a的另一部分设置有供从室内向室外排出的排出空气经过的流路。并且，干燥剂转动体185a可由电动机等驱动机构驱动旋转，换气用空气及排出空气可流向干燥剂转动体185a的各部分。作为吸附剂可使用沸石、硅胶、活性氧化铝等。Specifically, the humidifier 185 is provided with a flow path through which the ventilation air heated by the outdoor air heating heat exchange device 144 and supplied to the room passes through a part of the desiccant rotor 185a. In addition, another part of the desiccant rotating body 185a is provided with a flow path through which the discharge air discharged from the room to the outside passes. In addition, the desiccant rotating body 185a can be driven to rotate by a driving mechanism such as a motor, and the ventilation air and exhaust air can flow to each part of the desiccant rotating body 185a. Zeolite, silica gel, activated alumina and the like can be used as the adsorbent.

并且，在该加湿装置185中，在排出空气经过干燥剂转动体185a的除换气用空气经过的部分以外的部分时，排出空气中的水分被干燥剂转动体185a的吸附剂所吸附。并且，使干燥剂转动体185a旋转，移动到吸附了排出空气中的水分的部分与供换气用空气经过的流路对应的位置。于是，换气用空气经过吸附了排出空气中的水分的干燥剂转动体185a的一部分，利用由室外空气加热用热交换装置144加热后的换气用空气对干燥剂转动体185a的吸附了水分的部分进行加热，水分从该被加热的吸附剂中向换气用空气中脱离，从而可对换气用空气进行加湿后向室内供给。此时，通过干燥剂转动体185a的旋转，处于与干燥剂转动体185a的供换气用空气经过的流路对应的位置的干燥剂转动体185a的一部分移动到与干燥剂转动体185a的供排出空气经过的流路对应的位置，吸附排出空气中的水分。反复进行该动作，可连续地对换气用空气进行加湿。In addition, in the humidifier 185, when the exhaust air passes through the portion of the desiccant rotor 185a other than the portion through which the ventilation air passes, moisture in the exhaust air is adsorbed by the adsorbent of the desiccant rotor 185a. Then, the desiccant rotating body 185a is rotated to move to a position corresponding to the portion where the moisture in the exhaust air is adsorbed corresponds to the flow path through which the ventilation air passes. Then, the ventilation air passes through a part of the desiccant rotating body 185a that has adsorbed the moisture in the exhausted air, and the moisture absorbed by the desiccant rotating body 185a is absorbed by the ventilation air heated by the heat exchange device 144 for heating outdoor air. The part is heated, and the moisture is desorbed from the heated adsorbent into the ventilation air, so that the ventilation air can be humidified and supplied to the room. At this time, by the rotation of the desiccant rotor 185a, a part of the desiccant rotor 185a at a position corresponding to the flow path through which the ventilation air of the desiccant rotor 185a passes moves to the supply side of the desiccant rotor 185a. The position corresponding to the flow path through which the exhaust air passes, absorbs the moisture in the exhaust air. By repeating this operation, the ventilation air can be continuously humidified.

这样，在本变形例的空调系统101中，由于具有使用了吸附剂的加湿装置185，故利用换气用空气对吸附了水分的吸附剂进行加热，使水分脱离到换气用空气中，从而可对换气用空气进行加湿。另外，在空调系统101中，作为吸附剂吸附的水分利用了从室内向室外排出的排出空气中含有的水分，因此，不需向加湿装置185供水即可进行换气用空气的加湿。In this way, in the air conditioning system 101 of this modified example, since the humidifier 185 using the adsorbent is provided, the adsorbent to which the moisture is adsorbed is heated by the ventilation air to detach the moisture into the ventilation air, thereby Air for ventilation can be humidified. In addition, in the air conditioning system 101, the moisture contained in the exhaust air discharged from the indoor to the outdoor is used as the moisture adsorbed by the adsorbent, so that the ventilation air can be humidified without supplying water to the humidifier 185 .

另外，如图22所示，为了扩大加湿装置185的湿度调节范围等，也可使从室内向室外排出的排出空气(在图21的干燥剂转动体185a的左侧用RA表示)和与换气用空气不同的室外空气(在图21的干燥剂转动体185a的左侧用OA表示)的混合空气经过干燥剂转动体185a，由干燥剂转动体185a的吸附剂吸附水分，并使水分脱离到换气用空气中。In addition, as shown in FIG. 22, in order to expand the humidity adjustment range of the humidifier 185, etc., the exhaust air (indicated by RA on the left side of the desiccant rotating body 185a in FIG. The mixed air of outdoor air (indicated by OA on the left side of the desiccant rotating body 185a in FIG. into the ventilation air.

另外，在图22所示的加湿装置185中，使从室内向室外排出的排出空气及与换气用空气不同的室外空气双方经过干燥剂转动体185a，但也可仅使与换气用空气不同的室外空气经过。In addition, in the humidifier 185 shown in FIG. 22, both the exhaust air discharged from the room to the outside and the outdoor air different from the ventilation air pass through the desiccant rotor 185a, but it is also possible to let only the ventilation air Different outdoor air passes through.
