Tip: R134a has good chemical stability. However, because its water solubility is higher than that of R22, it is not good for the refrigeration system. Even if a small amount of water exists, it will be in the presence of water.refrigerated lubricating oilUnder the action of, acid, carbon dioxide or carbon monoxide will be generated, which will corrode the metal, or produce copper plating, so R134a has higher requirements for drying and cleaning the system. R134a has no chemical reaction with metals such as steel, iron, copper, and aluminum, but only has a slight effect on zinc.
