Abstract
An air conditioning apparatus including a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion valve to depressurize a refrigerant. The refrigerant is formed of hydro fluorocarbon (HFC). The compressor includes a compression unit to compress the refrigerant, a motor unit to provide rotational power 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, and the oil contains a carbon nanoparticle. Even when an HFC-based refrigerant producing high discharge temperature in a compressor is used, deterioration of the compressor due to the high temperature is prevented. In addition, by lowering the operational temperature of the compressor, the reliability and performance of the compressor using the HFC-based refrigerant and the air conditioning apparatus using the same may be enhanced.
