After condensation, form liquid refrigerant and be passed to throttling element (110) through gas-liquid separator, the refrigerant of low-temp low-pressure is in room after throttling
Absorb heat and evaporate from environment in external heat exchanger (112), the refrigerant vapour after evaporation enters the second separator through four-way valve (114)
(104) return compressor (102), due to the first separator (108) be in indoor heat exchanger (120) and throttling element (110) it
Between, the refrigerant of the first separator (108) is entered under heating operation mode for liquid, thus now the first separator (108)
Larger amount of refrigerant can be stored, thus reduce heat pump air conditioner indoor heat exchanger (120) it is too small when refrigeration, heat refrigerant
The unbalanced possibility of charging amount.
Technical scheme is described in detail above in association with accompanying drawing, the invention provides a kind of air-conditioning system and sky
Adjust, by the first separator connected between outdoor heat exchanger and indoor heat exchanger, and be connected to the first separator and four
Auxiliary branch between port valve, realizes the refrigerant separation circulation of gas-liquid binary states, reduces the circulating resistance of liquid refrigerant,
The efficiency of air-conditioning system is improved, meanwhile, the first separator can store larger amount of liquid refrigeration also when heating circulation
Agent, do not increase indoor heat exchanger content and on the premise of, solve heat pump air conditioner indoor heat exchanger it is too small when refrigeration, heat
The unbalanced problem of cryogen charging amount, reduces cost, saves space.
