汽车空调制冷舒适性的对比试验及评价

Comparative Test and Evaluation Standard of Vehicle Air Conditioner Cooling Performance

为了提升汽车空调的舒适性和用户驾乘体验,文章在行业标准QC/T 658—2000《汽车空调整车降温性能试验方法》的基础上,对某两款运动型多用途汽车车型进行汽车空调制冷性能和噪声的对比试验,并对试验结果进行比较分析。最后提出可使用降温速率和驾驶员耳旁噪声作为空调舒适性的两个评价指标,为汽车空调降温及噪声评价工作提供了工程参考依据。

In order to improve the comfort and driving experience of vehicle air conditioner, based on the industry standard QC/T 658—2000 Test Method for Cooling Performance of Vehicle Air Conditioner, this paper designs a comparative test on the cooling performance and noise of two SUV models, and archives a comparative analysis on the test results. The cooling rate and driver’s ear noise can be used as two evaluation indexes of air conditioning comfort, which provide engineering reference for the cooling and noise evaluation of vehicle air conditioning.
