Economic circular air conditioner
Technical field
The utility model relates to a kind of air conditioner, relates in particular to a kind of cold of new wind that utilizes and provides the nature cooling at transition season for building, to save the economic circular form air-conditioning of mechanical refrigeration energy consumption.
Background technology
The air source heat pump air-conditioner machine that is widely used is at present generally combined by accessories such as compressor, indoor and outdoor heat exchanger, four-way change-over valve, radiator fan, pressure fans.(as shown in Figure 1) when indoor environment temperature is too high or too low, unit starting compressor, pressure fan, radiator fan etc. freeze or heat supply running.This type is no matter how outdoor environment temperature changes, as long as indoor temperature has exceeded claimed range, unit is just forced cooling or heat supply by compressor operating, air conditioner refrigeration or the power consumption when heating comprise the operation power consumption of pressure fan, compressor, radiator fan etc., produce every kilowatt of cold or heat and probably need consume 2.5 kilowatts of left and right sides electric energy, so this type of type year operation power consumption is relatively large.
Summary of the invention
The utility model main purpose is the relatively large deficiency of air source heat pump air-conditioner machine year operation power consumption that solves prior art, thereby develops a kind of cold that utilizes new wind provides the nature cooling for building at transition season economy circulation air-conditioning.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of economic circular air conditioner, include compressor, outdoor heat converter, radiator fan, four-way change-over valve, indoor heat converter, pressure fan and electric control system thereof is characterized in that: system partitioning becomes return air and two independent sectors of air-supply; Between return air and supply air system, be provided with the return air air-valve of control return air amount; Be provided with the air draft air-valve of control exhaust air rate at air return system; Be provided with the new wind air-valve of control resh air requirement in supply air system; At the outdoor environment temperature sensor that is provided with, described sensor is electrically connected with electric control system.
As preferably, be provided with return air filter at return air inlet, be provided with new wind filter in new wind air-valve front.The air that enters is suitably purified.
The utility model monitors outdoor environment temperature when suitable when the outdoor environment temperature sensor, unit will move and change the economic scene operation over to, compressor, radiator fan etc. are out of service at this moment, the return air air-valve cuts out automatically, new wind air-valve and air draft air-valve are opened automatically, the new wind that outdoor temperature is lower is directly sent into room temperature lowering by pressure fan, thereby has saved compressor and radiator fan power consumption, has realized indoor free cold supply substantially.Therefore by economical operation, maximally utilising outdoor new air-cooled amount is indoor cooling, thereby it is minimum that the operation of air-conditioner energy consumption is dropped to.
Therefore, the beneficial effects of the utility model are:
1, this product makes full use of outdoor new wind and realizes free cold supply, and the air-conditioning system operating cost is saved in the most economical state operation of annual implementation to greatest extent.
2, micro computer Automatic Control, minimum fresh air requirmente control when solving the air conditioner whole year operation simply and effectively and brand-new wind operational management.
3, supporting air draft air-valve on the unit, indoor malleation is too high in the time of can effectively preventing the operation of brand-new wind.
4, economical operation control system that unit is supporting and normal cooling, heating system not only make things convenient for the mounting, commissioning and maintenance of air-conditioning system, have also saved air-conditioning system initial investment and operational and administrative expenses greatly.

The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
A kind of economic circular air conditioner as shown in Figure 2, compressor 8 is arranged, outdoor heat converter 6, radiator fan 7, four-way change-over valve, indoor heat converter 4, pressure fan 11 and electric control system thereof, air conditioner system is separated into return air and two independent sectors of air-supply, is provided with the return air air-valve 5 of control return air amount between return air and supply air system, is provided with the air draft air-valve 3 of control exhaust air rate at air return system, be provided with the new wind air-valve 10 of control resh air requirement in supply air system, be provided with new wind filter 9 in new wind air-valve front, be provided with return air filter 2 at return air inlet 1, at the outdoor environment temperature sensor that is electrically connected with electric control system that is provided with.
According to the variation of outside air temperature, regulate the different open degree of new wind air-valve 10, return air air-valve 5 and air draft air-valve 3 automatically.As in the winter time, when summer etc., outdoor environment was colder or warm, the air draft air-valve 3 of air conditioner, new wind air-valve 10 close valve, and (the new wind of new wind air-valve control about 10% guarantees the pure and fresh of room air, and can minimum fresh air requirmente be set) according to the use occasion difference, return air air-valve 5 is opened, corresponding unlatchings such as breeze fan 11, compressor 8, radiator fan 7 are carried out normal cooling and heating to the room conditioning room.The air conditioner air-flow as shown in Figure 3 at this moment.The principle of operation of air-conditioner and conventional air source heat pump basically identical enter indoor heat converter 4 from indoor by return air duct, return air inlet 1, by indoor heat converter cool off or heating after return air air-valve 5 send to indoor by breeze fan 11 again.
When the outdoor environment temperature sensor monitors outdoor environment temperature when suitable, unit will move and change the economic scene operation over to.Compressor 8, radiator fan 7 etc. are out of service at this moment, and return air air-valve 5 cuts out automatically, and new wind air-valve 10 and air draft air-valve 3 are opened automatically, and the air conditioner airflow direction as shown in Figure 4.The new wind that outdoor temperature is lower is directly sent into room temperature lowering (for guaranteeing the cleaning of room air, new wind porch is provided with new wind filter) by pressure fan, thereby has saved compressor and radiator fan power consumption, has realized indoor free cold supply substantially.The room air malleation is excessive when sending new wind on anti-, and unit is provided with air draft air-valve 3, and room air can be discharged in the surrounding environment by air draft air-valve 3 behind air conditioner by return air duct, return air inlet 1.
Because of the temperature of outdoor environment air is constantly changing, as the temperature difference, spring and autumn and the temperature difference in summer in winter in the temperature difference, daytime and the evening at early morning and noon or the like, and indoor environment tends to need cooling because of office equipment, plant equipment, lighting, personnel's or the like heat radiation, the place of heavy construction or personnel's comparatively dense particularly, therefore by economical operation, maximally utilising outdoor new air-cooled amount is indoor cooling, in night or transition season, only drive pressure fan and just can reach the indoor comfort degree requirement, thereby it is minimum that the operation of air-conditioner energy consumption is dropped to.
