Claims15
An air conditioner comprising:
- an outdoor unit which comprises a first heat exchanger;
- an indoor unit which comprises a second heat exchanger;
- an accumulator configured to separate a refrigerant discharged from the first heat exchanger or the indoor unit into a liquid refrigerant and a gas refrigerant;
- a compressor configured to compress the gas refrigerant discharged from the accumulator and to supply the compressed gas refrigerant to the first heat exchanger;
- a pump configured to pressurize the liquid refrigerant discharged from the accumulator and to supply the pressurized liquid refrigerant to the indoor unit;
- and
- a controller configured to control the air conditioner to cause the refrigerant to circulate through the first heat exchanger, the pump and the indoor unit without circulating through the compressor, based on a difference between an outdoor temperature and an indoor temperature and based on an outlet pressure of the pump and an inlet pressure of the pump.
