Technical field
The utility model relates to air-conditioning technical field, relates in particular to a kind of heat pump type air conditioner system.
Background technology
In heat pump type air conditioner system, traditional circulation theory that heats is: refrigerant becomes the cold-producing medium of high pressure-temperature through compressor compresses, the cold-producing medium that comes out from compressor becomes cold-producing medium warm the high pressure afterwards through indoor heat exchanger earlier, become the cold-producing medium of low-temp low-pressure again through throttling arrangement, in outdoor heat exchanger, evaporate again, get back to compress in the compressor forming one and heat circulation then.
Traditional heating in the cyclic process, the cold-producing medium of refrigerant temperature from indoor heat exchanger becomes after coming out becomes low-temperature refrigerant afterwards through throttling arrangement again, and this throttling step-down process makes the part thermal loss of refrigerant.
For improving the heating capacity of air-conditioning system, a solution that prior art adopts is: increased an economic heat exchanger and another expansion valve between indoor heat exchanger and expansion valve.System is when heating operation, after the high-temperature high-pressure refrigerant gas of discharging from compressor enters indoor heat exchanger (condenser) condensation heat release, be divided into two branch roads, one the tunnel to enter economic heat exchanger further cold excessively, and by inlet chamber external heat exchanger (evaporimeter) heat absorption after the expansion valve throttling step-down, get back to compressor then, another branch road is evaporation heat absorption in the inlet chamber external heat exchanger after expansion valve throttling step-down, then enters the auxilairy air intake of compressor.But, in this scheme, because warm refrigerant is divided into two-way after indoor heat exchanger comes out, one the tunnel is further cold excessively through economic heat exchanger, further mistake is cold just carries out the throttling step-down and another road does not have, thereby cause the thermal loss of the middle temperature refrigerant on another road to fall, this part heat fully can't be brought back to compressor.
Therefore, the net quantity of heat that the middle temperature refrigerant that prior art can't fully allow indoor heat exchanger come out when heating loses in throttling step-down process is got back to compressor, thereby has reduced the delivery temperature of compressor of air conditioner.
The utility model content
Main purpose of the present utility model is to provide a kind of air-conditioning system, and the heat that loses in the throttling step-down process when being intended to effectively to utilize traditional air-conditioning heating operation improves the delivery temperature of compressor of air conditioner, increases the air-conditioning heating capacity.
In order to achieve the above object, the utility model proposes a kind of air-conditioning system, comprise compressor, outdoor heat exchanger, indoor heat exchanger, the cross valve that is connected the throttling arrangement between outdoor heat exchanger and the indoor heat exchanger and connects described compressor, outdoor heat exchanger and indoor heat exchanger, this system also comprises: heat exchanger and expansion valve, described heat exchanger are connected between described indoor heat exchanger and the throttling arrangement; Described expansion valve is as bypass device, and an end connects heat exchanger, and the other end is connected between described throttling arrangement and the outdoor heat exchanger.
Preferably, described expansion valve is electric expansion valve, when the air-conditioning heating operation, described expansion valve is opened, a refrigerant part of coming out from described throttling arrangement flows to the outdoor heat exchanger evaporation of absorbing heat, another part refrigerant behind described expansion valve, become the lower refrigerant of temperature flow to heat exchanger neutralization from indoor heat exchanger come out warm refrigerant carry out heat exchange, return compressor; When air conditioner refrigerating moved, described expansion valve cut out, and got back to compressor successively behind described throttling arrangement, heat exchanger, indoor heat exchanger from the refrigerant that described outdoor heat exchanger comes out.
Preferably, described expansion valve is composed in series by magnetic valve and capillary, and described capillary is connected with described heat exchanger.
Preferably, described throttling arrangement is that electric expansion valve and capillary are composed in series, and described capillary is connected with described heat exchanger.
