制冷系统密封性试验方法

Tightness testing method of refrigerating system

密封性作为制冷系统可靠性研究的重要环节,特别是可燃制冷剂在制冷产品中的应用逐渐成熟,从安全的角度出发针对密封性的考核和判定就显得迫在眉睫。因此,介绍了ISO14903-2017中关于制冷系统密封性的一系列试验方法及要求。

Tightness is an important link in the reliability research of refrigerating system,especially the application of flammable refrigerant in refrigerating products is gradually maturing,it is extremely urgent to examine and judge the tightness level from the perspective of safety.Thus,a series of test methods and requirements of ISO 14903-2017 on the tightness of refrigerating systems are introduced.
