Description

INDUSTRIAL APPLICABILITY The present invention is a perimeter that is installed on the window side and can supply conditioned air to the window space in a living room partitioned from the outside through a window portion having a double-skin structure in which an interior space is formed. Regarding an air conditioning system equipped with an air conditioner.

As a conventional air-conditioning system, a system that supplies air-conditioned air from a perimeter air-conditioning device installed in a perimeter zone to the window space of a window portion having a double-skin structure is known (see, for example, Patent Document 1).

In the air-conditioning system described in Patent Document 1, the window portion (6) is configured in a double-skin structure in which a space (7) in the window through which air can be ventilated is formed between the glass arranged in double inside and outside. Below the window portion (6) on the living room side, a lower surface ventilation hole (31) for communicating the window interior space (7) and the living room side is opened. The perimeter air conditioner (100) is placed on the floor near the window portion (6), and the air-conditioned air blown out from the perimeter air conditioner (100) is a lower surface ventilation hole (7) leading to the window space (7). 31) It is said to be on the side of the living room in the vicinity. With such a configuration, a part of the conditioned air blown from the lower surface ventilation hole (31) to the living room side is supplied to the window space (7) through the lower surface ventilation hole (31).

In such an air-conditioning system, since the air-conditioned air flows through the window space of the window portion having a double-skin structure, the heat transferred from the outside to the window space can be treated by the air-conditioned air. Therefore, especially when the air conditioning load is high such as in summer or winter, it is possible to suppress heat transfer from the outside to the perimeter zone through the window, and improve energy saving and comfort of the perimeter zone. ..

Japanese Unexamined Patent Publication No. 5-240462 (mainly paragraph 0003, FIG. 9)

However, since the air conditioning system described in Patent Document 1 adopts a configuration in which air conditioning air always flows through the space inside the window, effective air conditioning can be performed when the air conditioning load is high, such as in summer or winter. However, when the air-conditioning load is kept low as in the middle period, the effectiveness of air-conditioning by the perimeter air-conditioning device becomes low, and there is a problem that the perimeter air-conditioning device cannot be used rationally.

In view of this situation, the main problem of the present invention is energy saving in an air conditioning system in which a perimeter air conditioner installed in a perimeter zone on the window side of a double-skin structure and capable of supplying air conditioning air to the space inside the window is installed. And while improving the comfort of the perimeter zone, it is to provide a technique for reasonably and effectively using the perimeter air conditioner.

The first characteristic configuration of the present invention is that in a living room partitioned from the outside via a window portion having a double-skin structure in which an interior space is formed, air-conditioned air is installed on the window portion side to the window interior space. It is an air conditioning system equipped with a perimeter air conditioner that can supply
The point is that the outlet of the air-conditioned air of the perimeter air conditioner is provided with a blowout destination switching means capable of switching between the space side in the window and the living room side.

According to this configuration, the air-conditioned air of the perimeter air conditioner is directly blown out to the air-conditioned space formed inside the window portion of the double-skin structure by the air-conditioning destination switching means with the air-conditioned air blown out to the window space side. In this state, even when the air-conditioning load is relatively high, such as in summer or winter, the heat transferred from the outside to the space inside the window is processed by the air-conditioned air, and the perimeter from the outside through the window. It is possible to suppress heat transfer to the zone and improve energy saving and comfort of the perimeter zone.
On the other hand, if the air-conditioned air of the perimeter air-conditioning device is set to the living room side by the above-mentioned blowing destination switching means and the air-conditioned air is directly blown into the living room, the air-conditioning load can be suppressed low as in the intermediate period. However, the air-conditioned air of the perimeter air-conditioning device can be effectively used for air-conditioning of the living room.
Therefore, according to the present invention, in an air conditioning system installed in a perimeter zone on the window side of a double-skin structure in a living room and equipped with a perimeter air conditioner capable of supplying air conditioning air to the space inside the window, energy saving and comfort of the perimeter zone are provided. It is possible to provide a technique for reasonably and effectively using a perimeter air conditioner while improving the above.

The second characteristic configuration of the present invention includes an interior air conditioner that air-conditions the living room, in addition to the perimeter air conditioner.
The air-conditioned air of the perimeter air conditioner is set to the living room by the outlet switching means during the start-up operation of the interior air conditioner, and the air-conditioned air of the perimeter air conditioner is blown out during the normal operation after the start-up operation. The point is that an operation control means for controlling the operation of the blowout destination switching means is provided in a form in which the tip is set in the window space by the blowout destination switching means.

According to this configuration, when the interior air-conditioning device having a relatively large air-conditioning load in the living room is started and operated, the air-conditioned air blowing destination of the perimeter air-conditioning device is set in the living room by the operation control of the air-conditioning destination switching means, and the perimeter air-conditioning device is concerned. Air-conditioned air is blown directly into the living room. Therefore, it is possible to process the air-conditioning load of a relatively large living room at the time of start-up operation by both the interior air-conditioning device and the perimeter air-conditioning device, and quickly bring the living room environment into a comfortable state. In particular, even if the interior air conditioner is a heat radiation type air conditioner or the like in which it is difficult to quickly handle a large air conditioning load in the living room by independent operation, the air conditioning air of the perimeter air conditioner is applied to the living room during the start-up operation. By blowing out, the rise time until the living room environment becomes comfortable can be shortened as compared with the start-up operation of the interior air conditioner alone.
Then, during normal operation after the start-up operation in which the living room environment becomes comfortable, the air-conditioned air outlet of the perimeter air conditioner is set in the window space by the operation control of the outlet switching means, and the perimeter air conditioner is operated. Air-conditioned air is blown directly into the window space. Therefore, while suppressing heat transfer from the outside to the perimeter zone through the window to maintain the comfort of the living room, it is possible to reduce the air conditioning load of the living room covered by the interior air conditioner and improve energy saving.

The third characteristic configuration of the present invention is a wall-through type air conditioner capable of executing an outside air intake air conditioning operation in which the perimeter air conditioner takes in outside air from the outside into the air conditioning air and discharges the indoor air taken in from the living room to the outside. It is a device.

According to this configuration, the ventilation of the living room can be enhanced by installing the wall-through type air-conditioning device as the perimeter air-conditioning device and causing the wall-through type air-conditioning device to execute the outside air intake air-conditioning operation. Further, such a wall-through type air conditioner is an air-cooled heat pump air conditioner in which an indoor unit and an outdoor unit are integrally configured, and the air-conditioned air is cooled or heated by using the outside air directly taken in through the outer wall as a heat source. Therefore, it is possible to realize a rational and lean system configuration by eliminating the need for installation work of another outdoor unit, refrigerant piping, and the like.

As shown in FIGS. 1 and 2, the living room R to be air-conditioned in the air-conditioning system of the present embodiment (hereinafter referred to as “the main air-conditioning system”) is partitioned from the outdoor O by the window portion 50. The window portion 50 has a double-skin structure in which the inner glass 52 and the outer glass 51 are arranged in double inside and outside at intervals from each other, and an interior space 55 is formed between them. Further, the space 55 in the window can accommodate a blind 53 in which the amount of light shielding from sunlight (sunlight) that enters the living room R can be adjusted. Further, in the waist wall portion 40 below the window portion 50, a space under the window portion C3 in which the perimeter air conditioner 30 described later is installed is formed.

A ceiling space C1 is formed above the ceiling panel 1 constituting the ceiling surface facing the living room R, and the upper end of the window space 55 is open to the ceiling space C1. A large number of ceiling surface air control ports 2 are bored in the ceiling panel 1. Further, the ceiling space C1 is provided with a ceiling chamber 12 provided so as to cover these ceiling surface air conditioning ports 2 and an interior air conditioner 10 capable of supplying air conditioning air SA to the ceiling chamber 12. There is.

The interior air conditioner 10 takes in the air in the ceiling chamber 12 as the return air RA to control the temperature, and supplies the air after the temperature control into the ceiling chamber 12 as the air conditioning air SA. Then, in the living room R, the conditioned air SA was blown out from a large number of ceiling surface air-conditioning ports 2 provided in the ceiling panel 1, and at the same time, the temperature was controlled by heat exchange with the conditioned air SA in the ceiling chamber 12. Air conditioning is performed by heat radiation from the ceiling panel 1. That is, the interior air conditioner 10 is configured as a heat radiation type air conditioner that air-conditions the living room R by using heat radiation from the ceiling panel 1.

An underfloor space C2 is formed below the floor panel 4 constituting the floor surface facing the living room R, and the underfloor space C3 is open to the underfloor space C2. A large number of floor air control ports 5 are bored in the floor panel 4.
In the perimeter zone Rp on the window portion 50 side, a perimeter air conditioner 30 capable of supplying conditioned air SA to the window interior space 55 or the like formed inside the window portion 50 in a form accommodated in the window portion lower space C3 is provided. Has been done. The conditioned air SA supplied from the perimeter air conditioner 30 to the bottom side of the window space 55 rises in the window space 55, then flows into the ceiling space C1, and then is taken into the interior air conditioner 10 as return air RA. become.

The perimeter air conditioner 30 is configured as a floor-standing type wall-through type air conditioner. In this type of wall-through type air conditioner, the indoor unit and the outdoor unit are integrally configured, and is configured as an air-cooled heat pump air conditioner that cools or heats the conditioned air SA by using the directly taken in outside air OA as a heat source. By adopting such a wall-through type air conditioner as the perimeter air conditioner 30, a rational and lean system configuration is realized by eliminating the need for installation work of another outdoor unit, refrigerant piping, and the like. There is.
Further, the air conditioning system is provided with an operation control device 60 that controls the operation of the interior air conditioning device 10 and the perimeter air conditioning device 30.

The perimeter air conditioner 30 is provided with an outside air intake port 37 and an exhaust port 38 that penetrate the outer wall 7 and are open to the outdoor O, and a return air intake port 39 that is open to the underfloor space C2. The perimeter air-conditioning device 30 is configured to be capable of performing an outside air intake air-conditioning operation in addition to the normal air-conditioning operation.
That is, in the normal air-conditioning operation, the indoor air that has flowed into the underfloor space C2 from the living room R through the floor control port 5 is taken in as the return air RA through the return air intake port 39 and is temperature-controlled, and the temperature is adjusted after the temperature control. The air RA is blown out as the air-conditioned air SA from the air-conditioned air outlet 31 to the window space 55 or the like.
On the other hand, in the outside air intake air conditioning operation, the outside air OA of the outdoor O is taken in through the outside air intake port 37 and the temperature is adjusted, and the outside air OA after the temperature adjustment is used as the air conditioning air SA from the air conditioning air outlet 31 to the window space 55. At least a part of the return air RA taken in as the return air RA through the return air intake port 39 is discharged to the outdoor O as the exhaust EA through the exhaust port 38. Then, by causing the perimeter air conditioner 30 to perform such an outside air intake air conditioning operation, ventilation to the living room R can be enhanced.

This air-conditioning system adopts a configuration for reasonably and effectively using the perimeter air-conditioning device 30 while improving energy saving and comfort of the perimeter zone Rp, and the details thereof will be described below.

An outlet switching valve 35 (an example of the outlet switching means) is provided so that the outlet of the air-conditioned air SA of the perimeter air conditioner 30 can be switched between the window space 55 side and the living room R side.
That is, the perimeter air-conditioning device 30 is provided with an conditioned air outlet 31 that blows out the conditioned air SA after temperature control. On the top surface of the waist wall 40 where the lower end of the window 50 is located, there are a window side outlet 32 that opens in the window space 55 and a living room side outlet 33 that opens in the perimeter zone Rp of the living room R. It is formed.
The outlet switching valve 35 is configured as a three-way switching valve interposed between the air-conditioned air outlet 31, the window space side outlet 32, and the living room side outlet 33, and is configured as a three-way switching valve, which will be described later. It is configured so that the blowing state (state shown in FIG. 1) and the living room blowing state (state shown in FIG. 2) can be switched.
That is, by switching the outlet switching valve 35 to the window space outlet state (state shown in FIG. 1), the air-conditioned air SA supplied from the air-conditioned air outlet 31 is supplied to the window space side outlet 32 side. It can be blown out from the window air outlet 32 to the window space 55. Further, by switching the outlet switching valve 35 to the living room blowing state (state shown in FIG. 2), the air-conditioned air SA supplied from the air-conditioned air outlet 31 is supplied to the living room side outlet 33 side and the living room side blowing. It can be blown out from the exit 33 to the perimeter zone Rp of the living room R.
The outlet switching valve 35 can be configured with one three-way switching valve as in the present embodiment, but the supply destination of the conditioned air SA from the conditioned air outlet 31 is the window space side outlet 32. Anything that can be switched between the air outlet 33 on the living room side and, for example, a two-way switching valve capable of intermittently supplying air-conditioned air from the air-conditioned air outlet 31 to the air outlet 32 on the window space side and an air-conditioned air blower. It can also be configured with a two-way switching valve capable of intermittently supplying air-conditioned air from the outlet 31 to the air outlet 33 on the living room side.

For example, as shown in FIG. 1, when the outlet switching valve 35 is switched to the window space outlet state and the air-conditioned air SA supplied from the perimeter air conditioner 30 is directly blown into the window space 55, it is summer or winter. Even when the air conditioning load is relatively high, such as, the heat transferred from the outdoor O to the window space 55 is processed by the air conditioning air SA. Therefore, heat transfer from the outdoor O to the perimeter zone Rp through the window portion 50 is suppressed, and energy saving and comfort of the perimeter zone Rp are improved.

On the other hand, as shown in FIG. 2, when the outlet switching valve 35 is switched to the living room blowing state and the air-conditioned air SA supplied from the perimeter air-conditioning device 30 is directly blown to the living room R, air conditioning is performed as in the intermediate period. Even when the load is kept low, the air-conditioned air SA of the perimeter air-conditioning device 30 is effectively used for air-conditioning the living room R.

The outlet switching valve 35 can be manually switched by the user, but in this air conditioning system, it can be automatically switched by the operation control device 60.
The operation control device 60 is configured to function as an operation control means for controlling the operation of the outlet switching valve 35 based on the operation state of the interior air conditioner 10 and the perimeter air conditioner 30.

That is, the operation control device 60 sets the outlet of the air-conditioned air SA of the perimeter air-conditioning device 30 to the living room R by controlling the operation of the blowing-out destination switching valve 35 during the start-up operation of the interior air-conditioning device 10, and the living room blowing state. (The state shown in FIG. 2). Then, the air-conditioned air SA of the perimeter air-conditioning device 30 is blown directly to the living room R, and the air-conditioning load of the relatively large living room R during the start-up operation is processed by both the interior air-conditioning device 10 and the perimeter air-conditioning device 30. become. As a result, the environment of the living room R becomes quick and comfortable. In particular, even if the interior air conditioner 10 is a heat radiation type air conditioner or the like in which it is difficult to quickly process a large air conditioning load in the living room R by independent operation, the air conditioning air SA of the perimeter air conditioner 30 is used during the start-up operation. By blowing out the air to the living room R, the start-up time until the environment of the living room R becomes comfortable is shortened as compared with the start-up operation of the interior air conditioner 10 alone.

Then, in the normal operation after the start-up operation in which the environment of the living room R becomes comfortable, the operation control device 60 controls the operation of the blow-out destination switching valve 35 to control the blow-out destination of the air-conditioned air SA of the perimeter air-conditioning device 30. The space inside the window is set to 55, and the space inside the window is blown out (the state shown in FIG. 1). Then, the conditioned air SA of the perimeter air conditioner 30 is directly blown out to the window space 55, and heat transfer from the outdoor O to the perimeter zone Rp through the window portion 50 is suppressed. As a result, while maintaining the comfort of the living room R, the air conditioning load of the living room R covered by the interior air conditioning device 10 is reduced, and the energy saving property is improved.
Further, the operation control device 60 appropriately executes and stops the outside air intake air conditioning operation by the perimeter air conditioning device 30 under appropriate conditions based on the temperature / humidity state of the living room R, the temperature / humidity of the outdoor O, the pollen concentration state, and the like. By switching, it is possible to further improve the energy saving property.
