Description of the Related Art Conventionally, various refrigerating machines such as automobile air conditioners (car air conditioners), refrigerators, indoor air conditioners (room air conditioners) have various refrigeration as lubricating oils. Machine oil is used. Since such refrigerating machine oil is used for a long period of time, a high degree of reliability is required. However, conventional refrigerating machine oils have been pointed out to have various drawbacks such as copper plating, poor stability, increase in total acid value, and sludge. Therefore, compositions in which various base oils and additives are variously combined have been proposed and used, but it is hard to say that all of them are practically satisfactory. In particular, as environmental problems have become more important in recent years and the use of specific CFC refrigerants that may cause ozone layer depletion has been stopped, alternative refrigerants for them are emerging, and the development of refrigerating machine oil suitable for them is desired. It is rare. However, the research and development of such refrigerating machine oil has just begun, and the fact is that sufficient research results have not yet been obtained.

We have conducted intensive research to develop refrigerating machine oil that can be applied not only to CFC refrigerants but also to various alternative refrigerants that pose no environmental pollution.
