摘要
总结分析了怠速状态下,汽车空调频繁启停化霜的常见原因。对某汽车空调系统进行了试验研究,结果发现:蒸发温度控制参数设置不当是其频繁启停的主要原因。通过分析蒸发温度控制参数对换热的影响,对该参数进行了优化设计。试验结果表明:蒸发温度控制参数优化设计后,空调系统运行性能良好,频繁启动的问题得到解决。
The common reason of frequent starting, stopping and defrosting of automobile air-conditioner at idle condition was summarized in the paper. Experimental study was carried out to one automobile air-condition system. According to the experiments, the improper setting of the parameter which control evaporating temperature was the main cause of frequent starting and stopping of automobile air-conditioner. By analyzing the influence on heat transfer of the parameter, the parameter was optimized. The experimental results show that the system works well and the problem of frequent starting of automobile air-conditioner is solved after optimizing the control parameter of evaporating temperature.
