本文阐述化工产品如 HCFC- 2 2替代物、冷冻机油以及清洗液、防锈液 (油 )、切削液 (油 )、气相防锈纸等辅助工艺材料在 R40 7C、R410 A混合工质的空调压缩机制造中应用的基本要求和筛选试验方法 ,即低温析出性和高温密封管的兼容试验。并结合实例说明兼容性试验不但在 R2 2工质压缩机而且在新工质压缩机生产中的重要性和必要性 This paper describes the chemical products such as HCFC-2 2 alternatives, refrigeration oil and cleaning fluid, antirust liquid (oil), cutting fluid (oil), gas rust paper and other auxiliary materials in the R40 7C, R410 A refrigerant mixture Compressor manufacturing applications in the basic requirements and screening test methods, that is, low temperature precipitation and high temperature sealed tube compatibility test. The practicality and necessity of the compatibility test not only in the R2 2 working fluid compressor but also in the new working fluid compressor
