摘　　要：针对某款商务车型设计了一套用CO_(2)热泵空调的整车热管理系统。通过一维CFD仿真软件Flowmaster对整车热管理系统进行建模并在NEDC工况下进行仿真分析,将CO_(2)空调与传统制冷剂R134a以及PTC电加热进行性能对比。结果表明:在夏季仿真过程中电机温度保持在90℃以下,电池组温度在40℃以内,乘客舱温度在开启空调的170 s后达到设定值,随后一直稳定在25℃;冬季仿真过程中,乘客舱温度在空调开启后147 s达到设定的25℃。冬夏季仿真均符合设计要求。A set of whole vehicle thermal management system with carbon dioxide heat pump air conditioning is designed for a commercial vehicle.Through one dimensional CFD simulation software Flowmaster,vehicle thermal management system modeling and simulation analysis are carried out under the NEDC condition,and the performance of carbon dioxide air conditioning is compared with that of traditional refrigerant R134a and PTC heating performance.The results show that during the simulation process in the summer,the motor temperature is kept below 90℃,the temperature of the battery pack is within 40℃,the passenger cabin temperature reaches set value at 170 s after air conditioning is turned on,then has remained steady at 25℃;In the winter simulation process,the passenger cabin temperature reaches the set 25℃at 147 s after the air conditioning is turned on,and the simulation in winter and summer meets the design requirements.
