What is refrigeration oil

Refrigeration oil is a lubricant used in refrigeration equipment, featuring excellent lubricity, compatibility with cooling media, low-temperature fluidity, and stability. The formulation and properties of refrigeration oil can be adjusted based on different application needs.

For example, some refrigeration oils may contain specific ester compounds or epoxide compounds to enhance their performance at low temperatures. Others may include polyvinyl ether compounds, polyoxyalkylene diol compounds, or polyol ester compounds to improve their thermal stability and oxidation stability. Additionally, the viscosity and pour point of refrigeration oil, among other physical properties, are also tailored to specific application environments.
