According to the CO2 heat management system for the vehicle, the working method and the vehicle provided by the invention, according to the CO2 heat management system for the vehicle, through the arrangement design of the pipelines and the valves, the refrigeration and heating requirements of a compartment and a battery can be met at the same time by using the same system architecture within a large environment temperature range, and the energy consumption is reduced. Particularly aiming at the thermodynamic property of CO2, a series/parallel hybrid heating mode of the battery and the compartment is realized through switching and control of a refrigerant loop, so that the heating capacity and efficiency of the system are effectively improved; in some modes, the heating capacity of the system is effectively improved, the application temperature range of the system is expanded, the use of PTC is avoided, the energy utilization efficiency is improved, and the problem that the endurance mileage of the electric vehicle is seriously attenuated due to low-temperature heating is effectively relieved through combined utilization of whole vehicle electronic components including a battery and environment air heat.

    本发明提供了提供一种车用CO2热管理系统、工作方法及车辆,根据本发明的车用CO2热管理系统,通过管路和阀的布置设计,实现了在较大的环境温度范围内使用同一套系统架构可以同时满足车厢与电池的制冷和制热需求,特别是针对CO2的热力学特性,通过制冷剂回路的切换和控制,实现电池和车厢的串/并联混合加热模式,从而有效提升系统制热量及效率;在某些模式下通过对包括电池在内的整车电子元器件及环境空气热量的组合利用,有效提高系统制热量,扩大了系统应用的温度范围,避免了PTC的使用,提高能量利用效率,有效缓解低温采暖导致电动汽车续航里程衰减严重的问题。
