电动客车变频热泵空调系统及其性能的试验研究

摘要

介绍了一套电动客车变频热泵空调系统，对样机在不同压缩机频率和不同风扇电机频率下的制冷/制热性能进行了试验研究，得出了相应的试验曲线，并分析了压缩机频率、风扇电机频率对系统性能的影响。电动客车采用变频热泵空调系统，通过调节压缩机和风扇电机的运转频率，可以达到提高空调系统性能和节能的目的。%A variable frequency heat hump air conditioning system for electric bus was described in this paper .A series of cor-responding curves was drawn according to the results of experiments on the sample .The influence of compressor frequency and fans frequency on the performance of the air condition system was discussed .The performance of air conditioning system can be improved as well as energy can be saved by adjusting compressor frequency and fans frequency .
