New demands for refrigeration oil extreme low viscosity oil.

Author(s) : MATSUMOTO T., KAIMAI T.

Summary

Improvement of energy efficiency is one of the effective methods for global environment protection. Using lower viscosity oil is known as an effective method, especially for small reciprocation compressors. Recently, it is attracted attention to use lower viscosity oil for hydrocarbon refrigerant applications. in this study, research and examination results about the development of low viscosity oils (lower than VG7) were reported. In general, the use of lower viscosity oil will be resulted in improvement of lubricity. However, there are other considerable problems, such as flash point, stability of base stocks, material compatibility (especially for organic materials), and refrigerant compatibility. Each problem was examined and extreme low viscosity oils, such as VG5 mineral oil, VG3 and VG5 ester oils were developed.
