The invention is suitable for the technical field of thermal management systems, and provides a CO2 heat pump and fire extinguishing integrated thermal management system and a control method. The system comprises a thermal management system in a passenger compartment and a battery fireproof system. When heating is conducted in the passenger compartment, CO2 gas is compressed by the compressor and then enters the indoor air cooler through the first electromagnetic valve to be cooled and dissipate heat, and heat is supplied to the passenger compartment. When fire extinguishing is conducted on the battery pack, CO2 gas obtained through pressure reduction and temperature reduction treatment of the second electronic expansion valve in the first pipeline sequentially enters the fire extinguishing agent storage tank, the pressure release valve, the high-pressure spray head set and the battery pack through the third electromagnetic valve; meanwhile, CO2 carries a fire extinguishing agent in the fire extinguishing agent storage tank to conduct fire extinguishing on the battery pack. In addition, the thermal management system in the passenger compartment and the battery fire prevention system are integrally designed, so that the design space can be saved; meanwhile, the thermal management system in the passenger compartment can assist the battery fire prevention system in fire extinguishing, and the fire extinguishing efficiency is improved.

    本发明适用于热管理系统技术领域,提供了一种二氧化碳热泵与灭火集成式热管理系统及控制方法。本发明包括乘员舱内热管理系统及电池防火系统;当进行乘员舱内制热时,二氧化碳气体经压缩机压缩后通过第一电磁阀进入所述室内气冷器中冷却散发热量,为乘员舱内供热;当进行电池包灭火时,第一管道中经第二电子膨胀阀降压降温处理得到的二氧化碳气体通过第三电磁阀依次进入灭火剂存储罐、泄压阀、高压喷头组及电池包,同时二氧化碳携带灭火剂存储罐中的灭火剂对电池包进行灭火。本发明通过将乘员舱内热管理系统与电池防火系统一体式设计,可以节省设计空间,同时乘员舱内热管理系统能够协助电池防火系统进行灭火,提升灭火效率。
