A refrigerant compressor comprising:
- an electromotor;
- and
- a compression element that is driven by the electromotor, includes a slider, and compresses a refrigerant,
- wherein a freezer oil that lubricates the slider is formed with a fullerene having a diameter that ranges from 100 pm to 10 nm as an additive,
- wherein an amount of the fullerene added is less than or equal to a saturation amount for dissolution of the fullerene with respect to the freezer oil,
- wherein the saturation amount for dissolution of the fullerene with respect to the freezer oil is a ratio at which a maximum amount of the fullerene is dissolved in the freezer oil in a dissolution phenomenon in which the fullerene is dispersed in the freezer oil so as to form a homogenous system.
