Abstract: 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.
