摘要: 空调发生制冷剂泄漏将影响制冷能力,甚至导致不制冷,因此空调在出厂前需要经过制冷系统泄漏检测。部分空调系统密封性差对空调的影响主要有两个方面:一是空气通过泄漏点进入系统,导致空调制冷效果下降;二是发生制冷剂泄漏,会出现制冷效果下降、压缩机使用寿命减少,甚至带来环境污染问题。结合国标对制冷空调设备密封性相关要求,对空调室外机密封性检测方法进行研究,通过气密性试验、真空试验、卤素检漏等多种方法,有效识别系统密封性差的空调,避免流入市场。

Abstract: Poor system sealing has two main impacts on air conditioning: firstly, air can enter the system through leakage points, leading to reduced cooling performance; secondly, refrigerant leaks can result in decreased cooling efficiency, reduced compressor lifespan, and even environmental pollution issues. Research on the sealing performance testing methods of air conditioning outdoor units, in accordance with the national standards related to the sealing requirements of refrigeration and air conditioning equipment. Various methods such as gas tightness tests, vacuum tests, and halogen leak detection are employed to effectively identify air conditioning units with poor seal integrity, thereby preventing them from entering the market.

Key words: Refrigerant leakage, Environmental pollution, Sealing integrity testing, Air tightness test, Vacuum testing, Fluorine leak detection
