Document Type and Number:
WIPO Patent Application WO/2023/010768
Kind Code:
A1
Abstract:
An air conditioning system (10), comprising an outdoor unit (11), a liquid pipe (12) for transmitting a two-phase refrigerant, and at least one indoor unit (131, 132). The outdoor unit (11) comprises an outdoor heat exchanger (111), a refrigerant phase change device (112), and a first electronic expansion valve (113) for reducing a pressure; the at least one indoor unit (131, 132) is connected to the first electronic expansion valve (113) of the outdoor unit (11) by means of the liquid pipe (12); the refrigerant phase change device (112) is connected to the first electronic expansion valve (113) and the outdoor heat exchanger (111), respectively; the refrigerant phase change device (112) is used for receiving, by means of the first electronic expansion valve (113) under a heating condition, the two-phase refrigerant flowing out of the at least one indoor unit (131, 132) through the liquid pipe (12), and changing the two-phase refrigerant into a liquid refrigerant; and the refrigerant phase change device (112) is further used for transmitting the liquid refrigerant obtained by phase change to the outdoor heat exchanger (111), such that the heat exchange evaporation efficiency of the outdoor heat exchanger (111) can be improved, and the heating effect of the air conditioning system (10) can be ensured in turn.
