Abstract

The invention discloses a heat-pump type electric automobile air conditioning system taking CO2 as a refrigerant and a working method thereof. The heat-pump type electric automobile air conditioning system taking CO2 as the refrigerant comprises a carbon dioxide refrigeration compressor, a gas-liquid separator, an automobile exterior cooler, an automobile exterior cooler fan, a heat regenerator, a plate heat exchanger, a water pump, an expansion tank, a heater core, an evaporator, an air blower, a two-position three-way valve, an electronic expansion valve a, an electronic expansion valve b, a solenoid valve a, a solenoid valve b, a solenoid valve c, a solenoid valve d, an air door, an automobile interior air flow passage a, an automobile interior air flow passage b and an automobile interior air flow passage c. According to the heat-pump type electric automobile air conditioning system taking CO2 as the refrigerant, a disadvantage caused by taking R134a as a refrigerant in the traditional heat-pump type automobile air conditioner is eliminated and the heating ability of the air conditioning system in winter is improved.

Description

technical field [0001] The present invention relates to automobile air conditioner, especially a kind of using CO 2 Refrigerant heat pump type electric vehicle air conditioning system and its working method. Background technique [0002] As one of the mainstream directions of automobile development at present, electric vehicles have the advantages of diversified energy utilization, quietness and pollution-free. Compared with traditional fuel vehicles, electric vehicles do not have engine heat utilization and cannot use traditional air conditioning systems. A heat pump system is a good solution with the advantage of high efficiency. [0003] At present, the electric vehicle air conditioning system mainly has the following disadvantages: [0004] 1. Some air-conditioning systems of electric vehicles adopt pure PTC heating method when heating, which is not energy-saving; [0005] 2. For the traditional heat pump type automotive air conditioner, the refrigerant is R134a, whi...
