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 demisting heating device, a compressor, an outdoor heat exchanger, an indoor heat exchanger and a battery pack cooling branch, a refrigerant can flow through the compressor, the outdoor heat exchanger, the indoor heat exchanger and the battery pack cooling branch, and the compressor, the outdoor heat exchanger and the indoor heat exchanger can be communicated through a first reversing valve to achieve refrigerant flow path reversing. The demisting heating device is arranged at the indoor heat exchanger. The battery pack cooling branch is located between the indoor heat exchanger and the outdoor heat exchanger, a first throttle valve is arranged on a refrigerant pipeline between the battery pack cooling branch and the outdoor heat exchanger, and a second throttle valve is arranged on therefrigerant pipeline between the battery pack cooling branch and the indoor heat exchanger. According to the vehicle-mounted air conditioning system, direct cooling and direct heating adjustment of the battery pack cooling branch can be achieved, and the temperature of the battery is kept within a proper range by adjusting the first throttling valve and the second throttling valve, so the heatingand cooling requirements of the vehicle and the battery heat management system under different working conditions are met.

    本发明公开了一种车辆、车载空调系统及其控制方法。车载空调系统包括除雾加热装置和可以流过冷媒的压缩机、室外换热器、室内换热器和电池包冷却支路,压缩机、室外换热器、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。除雾加热装置设于室内换热器处。电池包冷却支路位于室内换热器与室外换热器之间,电池包冷却支路与室外换热器之间的冷媒管路上设有第一节流阀,电池包冷却支路与室内换热器之间的冷媒管路上设有第二节流阀。根据本发明的车载空调系统,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使电池的温度保持在合适的范围内,以实现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。
