Compressor and air conditioning apparatus using the same

A compressor comprising:

• a compression unit to compress a refrigerant;
• a motor unit to provide rotational power to the compression unit through a rotating shaft connected to the compression unit;
• and
• an oil accommodation portion to store oil to reduce friction between the rotating shaft and the compression unit and lower a temperature of the compressor,
• wherein the compression unit comprises a cylinder to define a compression space to compress the refrigerant, a rolling piston connected to the rotating shaft to eccentrically rotate in the cylinder, and a vane protruding from an inner circumferential surface of the cylinder toward the rotating shaft to divide the compression space into a compression chamber for compression of the refrigerant and a suction chamber for suction of the refrigerant;
• the refrigerant is formed of hydrofluorocarbon (HFC);
• and
• the oil contains a carbon nanoparticle.

A compressor oil comprising:

• a mineral oil or synthetic oil;
• and
• carbon nanoparticles,
• wherein a mass fraction of the carbon nanoparticles contained in the oil is about 0.01% to about 0.3% of a mass of the oil.
