Abstract

The invention relates to an electric heat pump air-conditioning system for automobiles, which includes: an electric compressor with a communication part, the communication part includes an exhaust port, an air intake port and an air supply port; The indoor heat exchange device; the liquid storage and drying device connected with the outlet end of the indoor heat exchange device to form the second stroke channel; the intermediate heat exchange device connected with the outlet end of the liquid storage and drying device to form the third stroke channel ; communicate with the first outlet end of the intermediate heat exchange device to form an outdoor heat exchange device for the fourth stroke channel; wherein, the second outlet end of the intermediate heat exchange device communicates with the air supply port to form an air supply channel; exhaust The outlet port and the outlet of the indoor heat exchange device and / or the exhaust port and the outlet end of the outdoor heat exchange device are equipped with a pressure monitoring device that monitors the change in pressure difference and controls the amount of air supply according to the size of the pressure difference. The system has the advantage that the amount of air supply can be accurately regulated.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning systems, in particular to an electric heat pump air-conditioning system for automobiles. Background technique [0002] At present, the electric heat pump air conditioning system is mainly used to heat up and cool down the car, which brings comfort to the driver and passengers in the car. [0003] The electric heat pump air-conditioning system in the prior art mainly includes: electric frequency conversion compressor, outside air heat exchanger, inside air heat exchanger, mixed gas throttle valve, mixed gas control valve, liquid storage dryer, gas-liquid separation device etc. Among them, the outside air heat exchanger is mainly used for cooling to reduce the temperature inside the car, while the outside air heat exchanger is mainly used for heating and increasing the temperature inside the car. Wherein, the air intake port of the electric variable frequency compressor has an ...
