Abstract:
1. An air conditioner comprising: a compressor for compressing refrigerant; an indoor heat exchanger configured to condense refrigerant compressed by the compressor in a heating mode; an outdoor heat exchanger that discharges evaporated refrigerant; a four-way valve disposed at an outlet of the compressor to guide refrigerant to one of the indoor heat exchanger and the outdoor heat exchanger according to the heating mode and a cooling mode; a first pipe coupling the compressor and the four-way valve; a second pipe coupling the outdoor heat exchanger and the indoor heat exchanger; a heater; a third pipe coupling the second pipe and the heater; a fourth pipe coupling the heater and the four-way valve; a refrigerant heating device configured to receive the refrigerant from the indoor heat exchanger and heat the received refrigerant; and a bypass pipe configured to connect the first pipe to the outdoor heat exchanger, the bypass pipe guiding at least a portion of the refrigerant compressed by the compressor from the first pipe to the outdoor heat exchanger, wherein the third pipe allows the combined refrigerant to flow to the heater.
