How does POE oil behave differently compared to mineral oils in refrigeration systems?

POE (Polyol Ester) oil is specifically designed for use with HFC (hydrofluorocarbon) refrigerants and offers superior compatibility compared to mineral oils. One of the key properties of POE oil is its ability to effectively mix with the refrigerant, resulting in better lubrication and heat transfer within the refrigeration system. This solubility enhances the oil's overall performance, ensuring that it can circulate efficiently and maintain effective lubrication in systems where it operates with modern synthetic refrigerants that mineral oils cannot adequately serve.

In contrast, mineral oils have limitations when used with HFC refrigerants, as they are less capable of mixing with these oils. This can lead to ineffective lubrication and potential operational issues in the refrigeration system. The design and chemical properties of POE oils allow for enhanced compatibility, which is vital for the longevity and efficiency of refrigeration systems utilizing these modern refrigerants.
