In an automobile air conditioning system with variable compressor, there was a noise from a control valve at special range. An experimental study was conducted on elimination of noise and improving performance and quality. First, the cause of noise was analyzed through NVH tests of a control valve and a vehicle. Second, two methods were selected to improve the NVH; frequency change and inserting grease in control valve. Finally, the effect was verified.
