Problems solved by technology

[0003] At present, most electric vehicle heat pump air-conditioning systems use separate liquid receivers and gas-liquid separators to store refrigerants in different modes. In the heating mode, there is no liquid receiver to ensure that the refrigerant in front of the expansion valve is too high. Cold liquid, greatly reducing the heat transfer efficiency

Description

technical field [0001] The invention relates to the technical field of heat pump air-conditioning systems for electric vehicles, in particular to an automotive heat-pump air-conditioning system equipped with a multi-functional liquid storage device and an operating method thereof. Background technique [0002] With the development of automobile technology, the share of electric vehicles in vehicles is getting higher and higher, and more and more electric vehicle heat pump air-conditioning technologies have been researched and applied. Many electric vehicles at home and abroad have been equipped with heat pump air-conditioning systems. [0003] At present, most electric vehicle heat pump air-conditioning systems use separate liquid receivers and gas-liquid separators to store refrigerants in different modes. In the heating mode, there is no liquid receiver to ensure that the refrigerant in front of the expansion valve is too high. The cold liquid greatly reduces the heat tran...
