MIXED REFRIGERANT OF CHLORODIFLUOROMETHANE WITH CYCLOPROPANE AND APPARATUS FOR REFRIGERATING CYCLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain the subject mixed refrigerant excellent in refrigerating ability and coefficient of performance and useful for a refrigerant for a usual apparatus utilizing a refrigerating cycle because of forming an azeotropic mixture by mixing chlorodifluoromethane with cyclopropane in a specified ratio. ;SOLUTION: The subject mixed refrigerant is obtained by mixing 70 to 100wt.% (A) chlorodifluoromethane with ≤30wt.% (B) cyclopropane. Furthermore, a mineral oil, an alkylbenzene oil, and ester-based, ether-based and fluorine-based oils which are available when substituting a replacing refrigerant of fluorinated hydrocarbons not containing chlorine for a refrigerant are exemplified as a lubricating oil usable for an apparatus utilizing a refrigerating cycle with the refrigerant.;COPYRIGHT: (C)1997,JPO
