<P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle device capable of suppressing the decomposition of a refrigerant by suppressing the catalytic action of water molecules on the refrigerant by an intermolecular force of the refrigerating machine oil of a high water saturation amount, even if the water molecules are mixed in a refrigerating cycle using a substance having a carbon double bond as the refrigerant. <P>SOLUTION: In this refrigerating cycle device forming a refrigerating cycle by connecting refrigerant pipes of an outdoor unit 41 and an indoor unit 42 in installation, halogenated hydrocarbon having a carbon double bond in a composition, hydrocarbon having a carbon double bond in a composition, or a mixture including at least one of halogenated hydrocarbon having a carbon double bond in the composition or hydrocarbon having a carbon double bond in the composition is used as the refrigerant, and a first refrigerating machine oil having the water saturation amount of smaller than 200 ppm, and a second refrigerating machine oil having the water saturation amount of 2,000 ppm or larger are sealed in the refrigerating cycle device. <P>COPYRIGHT: (C)2010,JPO&INPIT |
