Abstract

The invention discloses a heat pump type vehicle air conditioner having a battery heat management function, which comprises a main refrigerant circulating loop configured to allow a refrigerant to flow in a sequence from a compressor, through a vehicle outside heat exchanger and an expansion valve, to a vehicle inside heat exchanger, or configured to allow the refrigerant to flow in a sequence from the compressor, through the vehicle inside the exchanger and the expansion valve, to the vehicle outside exchanger; and a defrosting loop configured to allow the refrigerant compressed by the compressor to sequentially flow through a defrosting throttle valve, the vehicle outside heat exchanger and a gas-liquid separator and then back into the compressor. The heat pump type vehicle air conditioner having the battery heat management function, provided by the invention, has a good defrosting effect with short defrosting time and low inside-vehicle temperature fluctuation, and can provide favorable comfort.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioning, and more particularly, relates to a heat pump type automobile air conditioner with battery heat management function. Background technique [0002] The electric vehicle industry is developing rapidly, but due to the characteristics of batteries and the diversity of electric vehicle application environments, it is currently difficult for electric vehicles to be widely used in severe cold areas and hot areas, or to run long distances. If the humidity outside the vehicle is high, it will cause frost or even ice on the external heat exchanger, which will seriously hinder the heat exchange of the external heat exchanger, and the heating performance of the heat pump air conditioner will be rapidly and greatly attenuated, which will significantly affect the heating performance of the heat pump air conditioner. thermal effects, and even cause the air conditioner compressor to fail. Fo...
