The invention provides a vehicle thermal management system, a vehicle and an operation method of the vehicle thermal management system. The vehicle thermal management system includes: a refrigerant fluid circuit in which a refrigerant fluid flows, the refrigerant fluid circuit including a compressor 1, a first heat exchanger 2, a high-pressure liquid drying tank 25, a heat transfer fluid-low-pressure refrigerant heat exchanger 22, an outdoor heat exchanger 3, a first expansion valve 4, an indoor heat exchanger 5, and a first flow path 13 selectively connected or disconnected; a heat transfer fluid flows in the heat transfer fluid loop, and the heat transfer fluid loop comprises a first heat exchanger 2, a first water pump 6, a heat transfer fluid-low-pressure refrigerant heat exchanger 22 and an outdoor radiator 7. The cost of the vehicle heat management system can be reduced, the superheat degree of the refrigerant at the inlet of the compressor does not need to be controlled to be just equal to 0, and the control complexity of the vehicle heat management system can be reduced.
本发明提供一种车辆热管理系统、车辆及车辆热管理系统的操作方法。该车辆热管理系统包括:冷媒流体回路,冷媒流体在其中流动,冷媒流体回路包括压缩机1、第一换热器2、高压液体干燥罐25、传热流体‑低压冷媒热交换器22、室外换热器3、第一膨胀阀4、室内换热器5以及选择性导通或截止的第一流路13;传热流体回路,传热流体在其中流动,传热流体回路包括第一换热器2、第一水泵6、传热流体‑低压冷媒热交换器22和室外散热器7。本发明能够降低车辆热管理系统的成本,且无需控制压缩机入口处的冷媒的过热度恰好等于0,能够降低车辆热管理系统的控制复杂度。
