Abstract

In order to solve a problem of adjusting effectively an air amount in the refrigerant, when difluoromethane (HFC32) is used for the refrigerant in the refrigerating cycle system, the present invention provides a refrigerating cycle system 1000 that is provided with a refrigerant circuit circulating a refrigerant 100 by connecting using pipes: a compressor 1 in which difluoromethane (HFC32) 10 as the refrigerant 100 and refrigerator oil including phenolic DBPC (2,6-di-t-b~t~l-~-craess aonl) a ntioxidant are sealed; a condenser 2; an expansion unit 3; and an evaporator 4, wherein an air amount (pressure) contained in the refrigerant 100 is 20 kPa or less.
