Definitions

  • the present invention relates to an air conditioner, and in particular to an air conditioner which is capable of implementing a package type indoor and outdoor unit for thereby enhancing a condensing efficiency.
  • a compressed refrigerant gas flows through a condenser(outdoor unit side heat exchanger) and is cooled and becomes a low temperature and pressure liquid state gas by a capillary vessel.
  • the liquid state gas is changed into a gas state by an evaporator(indoor unit side heat exchanger). At this time, a lot heat is exchanged for thereby sharply decreasing an indoor temperature.
  • the air conditioner may be used as a heating apparatus capable of increasing an indoor temperature by implementing a reversed flow of the refrigerant gas.
  • the above-described air conditioner is classified into an indoor unit installed in the indoor and outdoor unit installed in the outdoor.
