Title:
ENHANCED VAPOR INJECTION HEAT PUMP AIR CONDITIONING SYSTEM AND ELECTRIC VEHICLE COMPRISING HEAT PUMP AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/085956
Kind Code:
A1
Abstract:
An enhanced vapor injection heat pump air conditioning system and an electric vehicle comprising the heat pump air conditioning system. The heat pump air conditioning system comprises, sequentially connected end to end, a compressor (1), a first condenser (3), a first heat exchanger (6), a first expansion valve (7), and a second condenser (9). The first heat exchanger (6) comprises a first channel (61) and a second channel (62). A first end of the first channel (61) is in communication with the first condenser (3). A second end of the first channel (61) is in communication with the first expansion valve (7). A second expansion valve (8) is in communication with a first end of the second channel (62) and the first condenser (3). A second end of the second channel (62) is in communication with the compressor (1). A coolant entering the second channel (62) is depressurized and gasified by the second expansion valve (8) such that a temperature thereof is lower that that of the coolant in the first channel (61). Therefore, when the coolant in the first channel (61) flows through the compressor (1) again, the temperature of the compressor (1) is prevented from being overly high, such that the heat pump air conditioning system can also perform heating below -10°C to supply hot air to the interior an electric vehicle.
