Secondary loop air conditioner heat pump system for electric car

The invention relates to a secondary loop air conditioner heat pump system for an electric car. The secondary loop air conditioner heat pump system comprises a refrigerant loop and a secondary loop system. The refrigerant loop comprises an electric compressor, a plate-type condenser, a throttling device, a plate-type evaporator which are sequentially connected and used for refrigerant cycle. The secondary loop system comprises a cold end cooling liquid loop and a hot end cooling liquid loop. A flammable refrigerant cycles through a secondary loop and cannot make direct contact with a passengercompartment, and when the refrigerant is leaked, the danger level to passengers can be lowered; and meanwhile, the temperature of a battery pack can be controlled through the form of a secondary loopcooling liquid, so that a battery can exert the best performance during working, and meanwhile, heat in electronic equipment can be recycled through the cooling liquid. According to the secondary loop air conditioner heat pum
