摘要
文章介绍了冷媒脉动产生的机理,冷媒脉动是系统中的固有属性之一,只能减弱,无法彻底消除。在汽车空调中通过消声器的使用来降低系统脉动,介绍了几种汽车空调中常用消声器及消声频率计算,并通过两个实际应用案例降低了汽车空调脉动,消除异音。
This paper introduces the mechanism of the refrigerant pulsation, and the refrigerant pulsation is one of the inherent properties in the system, which can only be weakened and can not be completely eliminated. In automobile air conditioning, the use of muffler to reduce the system pulsation, this paper introduces several automotive air conditioning commonly used muffler and noise reduction frequency calculation, and through two practical applications to reduce the automotive air conditioning pulse, eliminate the abnormal sound.
