Abstract

The invention provides a water 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 water 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 water heat recycling system consists of a water-air bilateral cooling motor waste heat cooling device, an internal waste heat radiator, an external waste heat radiator, an external waste heat radiator fan, a waste heat recycling control device and a connecting pipeline. Due to the adoption of the water heat recycling heat pump air-conditioning system, 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, and the system can be used for stably and efficiently heating circularly at outdoor ultralow environmental temperature through the compressor cooling synergistic air mixing system and the automobile motor water heat recycling system.

Description

technical field [0001] The invention relates to an electric vehicle air conditioning system, in particular to a water 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 to its development. 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 this time, the air conditioning system of ordinary electric vehicles cannot work normally. This has seriously affected the popularity of electric vehicles in the northern region. Contents of the invention [0003] The purpose of the present invention is to provide an electric vehicle heat pump air conditioning system with a compressor cooling and efficiency mixing system and a drive motor water heat recovery system, so as to solve the problem that t...
