The invention provides a new energy automobile heat management system and a new energy automobile, and relates to the technical field of vehicles, the new energy automobile heat management system comprises a refrigerant loop and a first cooling loop, the refrigerant loop comprises a main loop and an air supplementing and enthalpy increasing loop, and the main loop comprises a compressor, a first heat exchanger and a second heat exchanger; a refrigerant discharged by the compressor circularly flows in the main loop, the air supply enthalpy increasing loop is connected with the air supply end of the compressor, and the first cooling loop is connected with the first heat exchanger. Medium-pressure gaseous refrigerants are supplemented to the compressor through the air supplementing and enthalpy increasing loop, the amount of the refrigerants entering the heat supply end heat exchanger is increased, the heating capacity is improved, the new energy automobile heat management system can well operate under the low-temperature working condition, the heating capacity does not need to be increased through electric heating, energy consumption can be reduced, and the service life of the new energy automobile heat management system is prolonged. And the first cooling loop and the main loop are adopted to form the secondary loop, the temperature of the passenger compartment is adjusted through the first cooling loop, leakage of the R290 refrigerant in the passenger compartment is avoided, and it is ensured that the R290 refrigerant is safely used.

    本发明提供了一种新能源汽车热管理系统及新能源汽车,涉及车辆技术领域,该新能源汽车热管理系统包括冷媒回路和第一冷却回路,冷媒回路包括主回路和补气增焓回路,主回路包括压缩机、第一换热器和第二换热器,压缩机排出冷媒在主回路内部循环流动,补气增焓回路与压缩机的补气端连接,第一冷却回路与第一换热器连接。通过补气增焓回路向压缩机补充中压的气态冷媒,提升进入供热端换热器的冷媒量,提升制热能力,使新能源汽车热管理系统在低温工况下也能良好运行,无需使用电加热来增加制热量,可降低能耗,并且采用第一冷却回路与主回路形成二次回路,通过第一冷却回路调节乘员舱温度,避免R290冷媒在乘员舱内发生泄漏,确保安全地使用R290冷媒。
