与传统汽车相比，电动汽车在冬季无法利用发动机的废热来给车内取暖。作为潜在的热源，配备涡旋压缩机的电动汽车空气源热泵（ASHP）和测试台旨在研究低环境温度下热泵系统的加热性能。针对电动汽车窗纱结露控制的需求，在全新风送风和各种室内进风温度条件下，在低环境温度-10℃、-15℃、-20℃下进行制热性能测试。实验结果表明，电动汽车空气源热泵由于新风比例大，与楼宇或家用空调有很大差异，即使在-20℃时，系统在最大热容量下的COP也超过1.7。
In comparison with the traditional cars, Electric Vehicles (EVs) cannot utilize the waste heat of the engines to keep warm inside the car in winter. As a potential heat source, air source heat pump (ASHP) for EVs with scroll compressor and test bench has been built to investigate the heating performances on heat pump system in low ambient temperature. Based on the demand of moisture condensation control on the window screen of EVs, the heating performances are tested on both all fresh air supply and various indoor air inlet temperature conditions, under low environmental temperature -10oC, -15oC and -20oC. The experimental results show that ASHP for EVs has big differences to buildings or household ACs due to its big ratio of fresh air, even at -20oC, the system's COP under the largest heat capacity is over 1.7.
