The invention provides a gas heat recycling heat pump air-conditioning system for an electric automobile. The system comprises an automobile totally enclosed variable-frequency air-conditioning compressor, an external air heat exchanger, an internal air heat exchanger, a liquid storing drier, a gas-liquid separator, a low-pressure throttling valve, a compressor cooling synergistic air mixing system, a driving motor gas heat recycling system, a system mode switching device and the like, wherein the automobile totally enclosed variable-frequency air-conditioning compressor is driven by using a direct-current motor; and the driving motor gas heat recycling system consists of a gas-gas bilateral cooling motor waste heat cooling device, a waste heat recycling control device and a connecting air duct. In the gas heat recycling heat pump air-conditioning system, five working modes, i.e., refrigerating in summer, ordinary heating in summer, ultralow-temperature heating, vehicle window defrosting / defogging and external low-temperature heat source heat exchanger surface defrosting can be realized for the electric automobile, and the system can be used for normally heating circularly at outdoor ultralow environmental temperature through the compressor cooling synergistic air mixing system and the driving motor gas heat recycling system.
Description
Technical field [0001] The invention relates to an electric vehicle air-conditioning system, in particular to an air-heat recovery type electric vehicle heat pump air-conditioning system. Background technique [0002] With the development of electric vehicle technology, electric vehicle air conditioners are becoming more and more restrictive. The reason is that due to the lack of internal combustion engines, heating in winter is greatly restricted, especially when the outdoor air temperature is very low. At that time, the air-conditioning system of the electric vehicle developed could not work properly. This has seriously affected the popularity of electric vehicles in the northern region. Summary of the invention [0003] The purpose of the present invention is to provide an air-heat recovery type electric vehicle heat pump air conditioning system to solve the problem that the current ordinary electric vehicle air conditioning system cannot normally heat when the outdoor tem...
