Compressor refrigeration system utilizing thermally stable refrigeration lubricants containing alkyl polyhalophenyl ethers

摘要

A compressor refrigeration system employing a halocarbon refrigerant, has a lubricant composition in contact with the halocarbon refrigerant over the expected temperature range of the system, the lubricant composition having lubricity and chemical and thermal stability in the presence of halocarbon refrigerant at temperatures of up to at least 130 DEG C., the lubricant composition comprising a thermally stable oil with minor amounts of an alkyl polyhalophenyl ether.
