The invention discloses a heat pump auxiliary device, a heat pump system, a control method of the heat pump system and a vehicle. The first compressor is arranged in the shell and is provided with a low-temperature refrigerant air inlet and a low-temperature refrigerant air outlet which are communicated with each other; the first heat exchanger is arranged in the shell and provided with a first low-temperature refrigerant outlet and a first low-temperature refrigerant inlet which communicate with each other, and the first low-temperature refrigerant outlet communicates with the low-temperature refrigerant air inlet; the second heat exchanger is arranged in the shell and provided with a second low-temperature refrigerant outlet and a second low-temperature refrigerant inlet which communicate with each other, the second low-temperature refrigerant inlet communicates with the low-temperature refrigerant exhaust port, and the second low-temperature refrigerant outlet communicates with the first low-temperature refrigerant inlet; the second heat exchanger is provided with a normal-temperature refrigerant inlet and a normal-temperature refrigerant outlet which communicate with each other. Therefore, the low-temperature refrigerant circulation system can be integrated in one shell, so that the arrangement space can be reduced, and refrigerant leakage is avoided.

    本发明公开了一种热泵辅助装置、热泵系统、热泵系统的控制方法和车辆,热泵辅助装置包括:外壳;第一压缩机,第一压缩机设置于外壳内且具有相互连通的低温冷媒进气口和低温冷媒排气口;第一换热器,第一换热器设置于外壳内且具有相互连通的低温冷媒第一出口和低温冷媒第一进口,低温冷媒第一出口和低温冷媒进气口相连通;第二换热器,第二换热器设置于外壳内且具有相互连通的低温冷媒第二出口和低温冷媒第二进口,低温冷媒第二进口与低温冷媒排气口相连通,低温冷媒第二出口与低温冷媒第一进口相连通,第二换热器具有相互连通的常温冷媒进口和常温冷媒出口。由此,可以将低温冷媒循坏系统集成在一个外壳内,从而可以减少布置空间,避免冷媒泄露。
