Abstract

An air conditioning system of the dynamoelectric automotive heat pump belongs to the field of the heat pump system structure. The invention contains the compressor, the four-through valve, the first unilateralism valve, the inner condensator, the F type heating power inflatable valve, the second unilateralism valve, the outer condensator, the first ending valve, the second ending valve, the H type heat power inflatable valve, the inner evaporator and the gas and liquid segregator. The exit of the compressor connects with the intake of the four-through valve. Two exits of the four-through valve separately connect with the intake of the first unilateralism valve and the inner condensator. The exit of the first unilateralism valve connects with the intake of the outer condensator. The exit of the inner condensator connects with the intake of the F type heating power inflatable valve. The exit of the F type heating power inflatable valve connects with the intake of the second unilateralism valve. The exit of the second unilateralism valve connects with the intake of the outer condensator. The exits of the outer condensator connect separately with the intakes of the first ending valve and the second ending valve. The exit of the first ending valve connects with the intake of the gas and liquid segregator. The structure of the invention is easy.

Description

technical field [0001] The invention relates to an air conditioner in the technical field of power machinery, in particular to an electric vehicle heat pump air conditioner system. Background technique [0002] At present, the air-conditioning system widely used in automobile air-conditioning can only meet the cooling requirements in summer working conditions, and the heating in winter working conditions mainly meets the comfort requirements of the car interior by using the engine cooling water with a higher temperature to heat the air. Traditional internal combustion engine vehicles heat the cabin air by using the waste heat from the engine, and cool it by directly using the engine to drive the compressor. Electric vehicles do not have a heat source like an engine, so they can only use a heat pump air-conditioning system with an electric compressor. However, the batteries used to power the heat pump system are mainly used to drive the car, and the energy consumption of the...
