Abstract

An electric automobile air conditioning system comprises a compressor, an electric-heating gas-liquid separator and a three-heat-exchanger set. The compressor and the electric-heating gas-liquid separator are connected, the three-heat-exchanger set is arranged between the compressor and the electric-heating gas-liquid separator in parallel and comprises a heater core, an outdoor heat exchanger and an evaporator, the heater core, the outdoor heat exchanger and the evaporator are sequentially connected in series, the heater core and the compressor are connected, the evaporator and the electric-heating gas-liquid separator are connected, and the outdoor heat exchanger is connected with the compressor and the electric-heating gas-liquid separator. Through arranging an electric-heating device inside the electric-heating gas-liquid separator at an air sucking opening of the compressor, working media discharged to the compressor are heated, the air-sucking specific volume of the compressor is reduced, the system flow is increased, the discharge temperature of the compressor is increased, and the heating capacity of the system is increased.

Description

technical field [0001] The invention relates to a technology in the field of automobile air conditioning, in particular to an electric automobile air conditioning system. Background technique [0002] The difference between electric vehicles and traditional fuel vehicles is that electric vehicles use batteries as driving power, without engine waste heat for heating, and cannot provide heat sources for automotive air conditioners in winter, and must use their own heating, that is, heat pump air conditioning systems . The battery used to power the heat pump air-conditioning system is mainly used to drive the car, and the energy consumption of the air-conditioning system has a great impact on the journey of the car every time it is charged. Experiments have proved that the performance of R134a refrigerant in the refrigeration cycle is worthy of recognition. In the heating cycle: when the ambient temperature is -10°C, the heat supply performance of the heat pump air-conditionin...
