The invention discloses a vehicle, a vehicle-mounted air conditioning system and a control method of the vehicle-mounted air conditioning system. The vehicle-mounted air-conditioning system comprisesa compressor, an outdoor heat exchanger, a first indoor heat exchanger and a battery pack cooling branch, a refrigerant can flow through the compressor, the outdoor heat exchanger and the first indoorheat exchanger, and the compressor, the outdoor heat exchanger and the first indoor heat exchanger can be communicated through a first reversing valve to achieve refrigerant flow path reversing. Thebattery pack cooling branch is located between the first indoor heat exchanger and the outdoor heat exchanger, one end of the battery pack cooling branch is communicated with the outdoor heat exchanger through a first throttle valve, and the other end of the battery pack cooling branch is communicated with the first indoor heat exchanger through a second throttle valve. According to the vehicle-mounted air conditioning system, direct cooling and direct heating adjustment of the battery pack cooling branch can be achieved, the temperature of a battery is kept within a proper range by adjustingthe first throttling valve and the second throttling valve, and the heating and cooling requirements of a vehicle and a battery heat management system under different working conditions are met in a more economical and more energy-saving mode.

    本发明公开了一种车辆、车载空调系统及其控制方法。车载空调系统包括可以流过冷媒的压缩机、室外换热器、第一室内换热器和电池包冷却支路,压缩机、室外换热器、第一室内换热器可以通过第一换向阀连通,以实现冷媒流路换向。电池包冷却支路位于第一室内换热器与室外换热器之间,电池包冷却支路的一端通过第一节流阀与室外换热器连通,电池包冷却支路的另一端通过第二节流阀与第一室内换热器连通。根据本发明实施例的车载空调系统,可以实现电池包冷却支路的直冷、直热调节,并通过调节第一节流阀和第二节流阀,以使电池的温度保持在合适的范围内,以更经济、更节能的方式满足了车辆以及电池的热管理系统在不同工况下的加热与冷却需求。
