电动汽车热泵空调系统在严寒地区的试验研究

Experimental study on heat pump air-conditioning system for electric vehicles in severe cold region

热泵空调系统作为电动汽车的辅助子系统,其能耗的降低对于提升电动汽车续航能力至关重要。本文试验对比分析电动汽车热泵空调系统和PTC电加热器的冬季制热性能,结果表明,热泵空调系统的制热效率约为PTC系统的2倍多,节省电量60%以上。

As the auxiliary subsystem of electric vehicle,it is important for heat pump air-conditioning system to reduce its energy consumption to improve the endurance of electric vehicles. The heating performance of heat pump air-conditioning system and PTC heater for electric vehicle in winter are compared by tests. The result shows that the heating efficiency of heat pump air-conditioning system is more than 2 times of that of PTC system,and the power consumption can be saved by over 60%.
