Abstract

The invention relates to an automobile air conditioning system integrating liquid storage with gas-liquid separation. The automobile air conditioning system comprises a refrigerant loop and a gas-liquid separation device. The refrigerant loop comprises a compressor, a condenser, a heat exchanger and an evaporator, and a refrigerant inlet of the compressor is connected with a refrigerant backflow pipeline. The gas-liquid separation device comprises a liquid storage tank, a coaxial pipe and a first valve. The liquid storage tank is provided with a feeding end, a gas outlet end and a liquid outlet end. The coaxial pipe comprises an outer fluid pipeline and an inner fluid pipeline which are coaxially arranged, the gas outlet end and the liquid outlet end are installed at the same end of the coaxial pipe, the gas outlet end is connected with an inner fluid pipeline, the liquid outlet end is connected with an outer fluid pipeline, the other end of the coaxial pipe is connected with the evaporator, the inner fluid pipeline is further connected with the refrigerant backflow pipeline, and the first valve is installed at the gas outlet end. The communicating part of the refrigerant backflow pipeline with the inner fluid pipeline is positioned between the first valve and the compressor. Noise can be eliminated, and the refrigerating effect is improved. And the liquid impact risk of the compressor is avoided.

Description

Technical field [0001] The present invention relates to a heat pump type automotive air conditioning system technologies, and particularly relates to an integrated gas-liquid separator and the reservoir automotive air conditioning system. Background technique [0002] In the car for EV (Electric Vehicle, an electric vehicle), HEV vehicles (Hybrid Electric Vehicle, hybrid vehicles), and PHEV vehicles (Plug-in Hybrid Electric Vehicle, plug-in hybrid vehicles) and other automotive air conditioning systems, can not be the heating operation by the engine cooling water heat of the combustion exhaust embodiment. Therefore, it is considered a system using an electric heat pump type air compressor, but using the reversing heat pump, it must share constituting the refrigerant circuit piping and the evaporator class under different pressure conditions in the cooling operation and the heating operation, the condenser such as heat exchangers, etc., it is necessary to conduct a comprehensive i...
