The invention relates to the technical field of whole vehicle heat management of pure electric vehicles, in particular to a heat pump system based on an air-supply enthalpy-increasing compressor and a double-spiral vortex tube. Comprising a first refrigerant loop and a second refrigerant loop, and the first refrigerant loop is arranged at the top of the second refrigerant loop. According to the heat pump system based on the air supply enthalpy increasing compressor and the double-spiral vortex tube, the double-spiral vortex tube is used as an intermediate heat exchanger of an air supply branch, the structure is simple, the working temperature of the compressor is effectively reduced, the working efficiency of the compressor is improved, and the loss of the compressor is reduced; the temperature of the compressor is reduced, the efficiency of the compressor is improved, high-temperature gas coming out of the double-spiral vortex tube enters the second in-vehicle heat exchanger and is thermally coupled with the first in-vehicle heat exchanger to jointly heat a passenger compartment, the heating effect is improved, and the problem that an existing gas-supplementing enthalpy-increasing heat pump system is poor in heating effect within the temperature range of-5 DEG C to 0 DEG C is solved.

    本发明涉及纯电动汽车整车热管理技术领域,尤其涉及基于补气增焓压缩机、双螺旋涡流管的热泵系统。包括第一冷媒回路和第二冷媒回路,第二冷媒回路的顶部设置有第一冷媒回路。本发明提供的基于补气增焓压缩机、双螺旋涡流管的热泵系统,通过使用双螺旋涡流管作为补气支路的中间换热器,结构简单,有效降低压缩机的工作温度,提高其工作效率,减小压缩机的损耗,同时通过使用双螺旋涡流管作为中间换热器,降低压缩机温度,提高压缩机效率,从双螺旋涡流管出来的高温气体进入第二车内换热器,与第一车内换热器热耦合共同为乘员舱制热,增加了制热效果,改善了现有补气增焓热泵系统在‑5℃~0℃温度范围内制热效果差的问题。
