PROBLEM TO BE SOLVED: To solve such a problem that, when ethylene fluorohydrocarbon where polymerization easily occurs is used as refrigerant, the refrigerant is changed into gas in slide parts of a compressor and a winding part of a motor which are subjected to a high temperature, and so polymerization inhibitor, if added to the refrigerant, is moved out as it is contained in the gas, without being delivered into the slide parts of the compressor and the winding part of the motor, thus making it difficult to sufficiently develop the effects of preventing the polymerization of the refrigerant.SOLUTION: A refrigerant compressor using the ethylene fluorohydrocarbon or mixture containing it as the refrigerant includes: a compression element for compressing the refrigerant; slide components provided in the compression element for constituting the slide parts; and refrigeration oil to be supplied to the slide components for lubricating the slide parts. It uses the refrigerant as well as the refrigeration oil containing the polymerization inhibitor for suppressing the polymerization of the refrigerant. |
