Abstract

The invention discloses a heat pump air conditioning system, an electric vehicle and a control method thereof. The heat pump air conditioning system comprises an enthalpy compressor (11), a first indoor heat exchanger (32), a flash evaporator (12) and an outdoor heat exchanger (31); an exhaust end of the enthalpy compressor (11) communicates with a refrigerant inlet of the first indoor heat exchanger (32); a refrigerant outlet of the first indoor heat exchanger (32) communicates with a first inlet and outlet end of the flash evaporator (12); a second inlet and outlet end of the flash evaporator (12) communicates with a first refrigerant inlet and outlet of the outdoor heat exchanger (31); a second refrigerant inlet and outlet of the outdoor heat exchanger (31) communicates with a suction end of the enthalpy compressor (11); and an air supply end of the flash evaporator (12) communicates with an air supply opening of the booster compressor (11). According to the scheme, the defects of large energy consumption, inconvenient operation and poor user experience in the prior art can be overcome, and the beneficial effects of small energy consumption, convenient operation and good user experience are achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, specifically relates to a heat pump air conditioning system, an electric vehicle and a control method thereof, in particular to an automatic air conditioner for a frequency conversion heat pump type electric vehicle, an electric vehicle with the air conditioner, and a control method for the electric vehicle. Background technique [0002] Compared with traditional cars, pure electric vehicles cannot use the waste heat of the engine, and the cabin heating in winter cannot directly obtain heat from the heater core like traditional cars. Therefore, the air conditioning system of pure electric vehicles is fundamentally different from the traditional car air conditioning system. [0003] At present, the electric vehicle air conditioning system in the industry generally adopts the "single cooling system + PTC (Positive Temperature Coefficient, thermistor) heating" scheme; this scheme replaces th...
