The vehicle-mounted air-supplementing enthalpy-increasing carbon dioxide heat pump air conditioning system comprises a compressor, the compressor is sequentially connected with a condenser, a liquid storage device, a drying filter, a liquid viewing mirror, an economizer, an evaporator, a first one-way valve, a gas-liquid separator and an air blower, and the liquid viewing mirror, the economizer, the evaporator and the compressor are communicated through a main pipeline and an auxiliary pipeline. A first electromagnetic valve and a first expansion valve are arranged on the portion, between the liquid viewing mirror and the economizer, of the main pipeline, a second electromagnetic valve and a second expansion valve are arranged on the portion, between the economizer and the evaporator, of the main pipeline, and a first one-way valve is arranged on the portion, between the economizer and the compressor, of the auxiliary pipeline. According to the vehicle-mounted air-supplementing enthalpy-increasing carbon dioxide heat pump air-conditioning system, the problems that when a common scroll compressor operates at a low evaporation temperature, the suction specific volume is increased, the pressure ratio is increased, the exhaust temperature is rapidly increased, the performance of the compressor is sharply reduced, the heating capacity is insufficient, and the compressor is difficult to operate are solved.

    本发明公开了车载补气增焓二氧化碳热泵空调系统,包括压缩机,压缩机依次连接有冷凝器、储液器、干燥过滤器、视液镜、经济器、蒸发器、第一单向阀、气液分离器和鼓风机,且视液镜、经济器、蒸发器和压缩机之间通过主路和辅路管道连通,且视液镜和经济器之间的主路管道分别设有第一电磁阀和第一膨胀阀,经济器与蒸发器之间的主路管道分别设有第二电磁阀和第二膨胀阀,经济器与压缩机之间的辅路管道设有第一单向阀,本发明涉及车载空调技术领域。该车载补气增焓二氧化碳热泵空调系统,解决解决普通涡旋压缩机在低蒸发温度下运行时,会发生吸气比容增大、压比升高,排气温度快速升高,以及造成压缩机性能急剧下降和制热量不足以及难以运行的问题。
