Abstract
The utility model discloses a heat pump system for recovering air-conditioner exhaust air, which includes a compressor and a gas and liquid separator arranged in a refrigerant circulating system. The compressor is connected with two refrigerant circulating branches through a four-way reversing valve, wherein the first branch is communicated to a fresh air heat exchanger, then passes through a high-pressure liquid accumulator, a drying filter and a first expansion valve sequentially, is communicated to an exhaust air heat exchanger, and then is communicated with the gas and liquid separator; and the second branch is communicated to the exhaust air heat exchanger, then passes through the high-pressure liquid accumulator, the drying filter and a second expansion valve sequentially, is communicated to the fresh air heat exchange, and then is communicated with the gas and liquid separator. The heat pump system for recovering air-conditioner exhaust air provided by the utility model effectively utilizes the cool quantity and the heat quantity of the exhaust air under different working conditions, so as to precool or preheat the fresh air, reduce the cool and heat load of fresh air treatment, and have obvious energy-saving effect.
Description
Technical field
The present invention relates to a kind of heat pump, more particularly, relate to the improvement of heat pump circulating system.
Background technology
In annual total refrigeration duty of building and the annual total heat duties, the cooling and heating load of new wind has accounted for greatly.Send into the new wind of air-conditioned room, main purpose is to satisfy hygienic requirements in the room, finally will be discharged to outdoor by exhaust system.Utilize cold and heat in the air-conditioning air draft, come the new wind of precooling and preheating, reduce the cooling and heating load that new wind is handled, can reach purpose of energy saving.
Summary of the invention
The present invention reclaims the heat pump of air-conditioning air draft, and by utilizing cold and the heat in the air-conditioning air draft, the new wind of precooling and preheating reduces the cooling and heating load that new wind is handled, and finally reaches energy-conservation purpose.
In order to achieve the above object, the invention provides a kind of heat pump that reclaims the air-conditioning air draft, comprise the compressor and the gas-liquid separator that are provided with in the refrigerant-cycle systems.Described compressor connects two cold-producing medium circulation branch roads by a four-way change-over valve.Wherein, first branch road is communicated to fresh air heat exchanger, and by being communicated to the air draft heat exchanger through high pressure reservoir, device for drying and filtering, first expansion valve successively behind the described fresh air heat exchanger, then is communicated with back described gas-liquid separator.Second branch road is communicated to described air draft heat exchanger, and by being communicated to fresh air heat exchanger through high pressure reservoir, device for drying and filtering, second expansion valve successively behind the described air draft heat exchanger, then is communicated with back described gas-liquid separator.
In addition, the front portion that described first branch road is positioned at described first expansion valve is provided with first check valve, and the front portion that described second branch road is positioned at described second expansion valve is provided with the 4th check valve, and this makes synchronization only have the branch road can periodic duty.And in order to simplify pipeline, there are common pall in described first branch road and described second branch road, and second check valve and the 3rd check valve are set, and play buffer action.
The heat pump that the present invention reclaims the air-conditioning air draft has effectively utilized the cold and the heat of air draft under the different operating modes, makes new wind obtain precooling or preheating, has reduced the cooling and heating load that new wind is handled, and energy-saving effect is remarkable.
Description of drawings
Fig. 1 is the heat pump operation principle schematic diagram that the present invention reclaims the air-conditioning air draft.
The specific embodiment
System of the present invention as shown in Figure 1 is the thermal source of heat pump with the air-conditioning air draft, utilizes four-way change-over valve to finish operating mode and switches, and specifically, comprises the compressor 2 and the gas-liquid separator 1 that are provided with in the refrigerant-cycle systems.Compressor 2 connects two cold-producing medium circulation branch roads by a four-way change-over valve 3.Wherein, first branch road is communicated to fresh air heat exchanger 14, and by being communicated to air draft heat exchanger 4 through high pressure reservoir 7, device for drying and filtering 8, first expansion valve 5 successively behind the fresh air heat exchanger 14, then is communicated with back described gas-liquid separator 1.And second branch road is communicated to air draft heat exchanger 4, and by being communicated to fresh air heat exchanger 14 through high pressure reservoir 7, device for drying and filtering 8, second expansion valve 13 successively behind the air draft heat exchanger 4, then is communicated with back described gas-liquid separator 1.
Under the optimal way, the front portion that described first branch road is positioned at described first expansion valve 5 is provided with first check valve 6, and the front portion that described second branch road is positioned at described second expansion valve 13 is provided with the 4th check valve 4.And there are common pall in described first branch road and described second branch road, and second check valve 10 and the 3rd check valve 11 are set.
During winter, the high-temperature gas cold-producing medium that comes out from compressor enters the fresh air heat exchanger, carries out heat exchange with new wind, and the condensation heat release is called liquid state, and new wind is preheated.The liquid refrigerant that goes out fresh air heat exchanger is through expansion valve throttling step-down, enter air draft heat exchanger evaporation heat absorption after, become low-temperature steam and get back to compressor.That is to say that during winter, a large amount of heats are carried in the air draft of air-conditioning.New wind enters fresh air heat exchanger, and the refrigeration working medium that comes out with compressor carries out heat exchange, and refrigeration working medium cooling heat release makes new wind be preheated.
During summer, the high-temperature gas cold-producing medium that comes out from compressor enters in the air draft heat exchanger by the switching of four-way change-over valve, carries out heat exchange with the air draft that temperature is lower, is condensed into liquid state.Through entering fresh air heat exchanger after the expansion valve throttling step-down, with new air heat-exchange, the evaporation heat absorption is refrigerant gas, and with new wind precooling.That is to say that during summer, the air draft of air-conditioning is comparatively nice and cool, carries a large amount of colds.Air draft enters the air draft heat exchanger refrigeration working medium is cooled to liquid, and liquid refrigeration working medium enters fresh air heat exchanger through throttling and carries out heat exchange with new wind, and the evaporation heat absorption reduces new wind-warm syndrome degree.
In addition, among Fig. 1, a represents new wind, and b represents air draft; Filled arrows is represented the circulating path of winter refrigeration agent, and hollow arrow is represented the circulating path of cold-producing medium in summer.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
