The invention provides a combined gas-water dual-heat-source heat pump air-conditioning system for an electric automobile. The air-conditioning system is characterized by comprising an automobile totally enclosed variable-frequency air-conditioning compressor, an external combined gas-water dual-heat-source heat exchanging device, an internal dual-heat-source graded heating device, a power motor waste heat recycling system, a liquid storing drier, a low-pressure throttling valve, a gas-liquid separator, a system mode switching device, a compressor cooling synergistic air mixing system and thelike, wherein the automobile totally enclosed variable-frequency air-conditioning compressor is driven by using a direct-current motor. In the invention, five working modes, i.e., refrigerating, ordinary heating, low-temperature heating, vehicle window defrosting / defogging and external low-temperature heat source heat exchanger surface defrosting of the electric automobile can be realized by reasonably utilizing the compressor cooling synergistic air mixing system, the external combined gas-water dual-heat-source heat exchanging device and the internal dual-heat-source graded heating device in the heat pump air-conditioning system.
Description
technical field [0001] The invention relates to an electric vehicle air conditioning system, in particular to a combined air-water dual heat source heat pump type electric vehicle air conditioning system. [0002] Background technique [0003] With the development of electric vehicle technology, electric vehicle air conditioners are becoming more and more restrictive to its development. The reason is that heating in winter is greatly restricted due to the lack of internal combustion engines. The currently developed air-conditioning system for electric vehicles will cause the exhaust temperature of the compressor to be too high when the outdoor ambient temperature is too low, making it unable to operate normally during low-temperature heating. Therefore, the system mode of the refrigeration system and electric heating is basically used to cooperate , thereby greatly increasing the power consumption during heating in winter, seriously affecting the application and popula...
