摘要：
PROBLEM TO BE SOLVED: To prevent generation of wax-like solid material causing clogging of a refrigerating circuit and degradation of refrigerating performance, in the refrigerating circuit wherein a vane rotary compressor is used as a compressor, an unsaturated fluorinated hydrocarbon refrigerant is used as a refrigerant, and an ether lubricant such as polyalkylene glycol is used as a refrigerating machine oil.
SOLUTION: A lubricant type component not having a polyoxyalkylene structure such as ester lubricant, alcohol friction modifier, olefin friction modifier, polyolefin lubricant, alkyl aromatic lubricant and silicone lubricant, or a metal deactivation agent such as benzotriazole is added to the ether lubricant such as polyalkylene glycol, to prevent generation of the wax-like solid material in the refrigerating circuit.
