The invention relates to the technical field of fuel cell automobile thermal management, relates to a thermal management technology of a fuel cell automobile, and in particular relates to a whole fuel cell automobile thermal management system and a control method. According to the whole vehicle thermal management system of the fuel cell vehicle, the four-way valve and the three-way valve of the refrigerant loop and the five-way valve of the cooling liquid loop are used for changing the refrigerating mode and the heating mode. In the heating mode, the motor waste heat and the heat pump air conditioner are fully utilized to assist the PTC heater in heating, the power consumption of the whole system is reduced, and the cold start performance of the fuel cell automobile is improved; in the refrigeration mode, the waste heat of the fuel cell stack can be used for heating the cab, so that the waste of energy is reduced, and the driving range of the automobile is increased.

    本发明涉及燃料电池汽车热管理技术领域,为一种燃料电池汽车的热管理技术,具体为一种燃料电池汽车整车热管理系统及控制方法;本发明提供的燃料电池汽车整车热管理系统利用制冷剂回路的四通和三通阀,冷却液回路的五通阀进行制冷和制热模式的改变。在制热模式下,充分利用了电机余热和热泵空调辅助PTC加热器进行加热,降低了整体系统的功耗,并且改善了燃料电池汽车冷启动的性能;在制冷模式下,可以利用燃料电池电堆余热对驾驶舱进行加热,减少了能量的浪费,增加了汽车的续驶里程。
