To provide a refrigerating cycle device, which can suppress the decomposition of a refrigerant by suppressing the catalytic action of a water molecule to the refrigerant, by the intermolecular force of freezer oil high in volume of saturated water content, even if water molecules mix in a refrigerating cycle in which a substance having the double coupling of carbon is used as the refrigerant.
This refrigerating cycle device has such features that the different points of the refrigerating cycle are charged with first freezer oil under 200 ppm in saturated water content and second freezer oil 2,000 ppm or over in saturated water content, in the refrigerating cycle device in which a refrigerating cycle is made by connecting the refrigerating pipes of an outdoor unit 41 and an indoor unit 42 with each other at installation. For example, the first freezer oil is filled in a compressor and the second freezer oil is filled in other part (for example, a receiver) than the compressor.
