Abstract: An air conditioner may include a case having a supply channel therein through which external air flows into an interior space; a first heat exchanger disposed on the supply channel and in which the air and refrigerant exchange heat; a second heat exchanger disposed at a downstream side of the first heat exchanger in the supply channel, and in which the air and refrigerant exchange heat; and a refrigerant distributor that sends refrigerant to the first heat exchanger or the second heat exchanger. The refrigerant distributor may include a liquid pipe connected with the first heat exchanger and through which liquid-state refrigerant flows; a first gas pipe connected to the first heat exchanger and the second heat exchanger and through which gas-state refrigerant flows; a second gas pipe through which gas-state refrigerant discharged from the first heat exchanger flows; a first gas pipe valve disposed on the first gas pipe and that sends refrigerant flowing through the first gas pipe to the first heat exchanger or the second heat exchanger; and a second gas pipe valve disposed on the second gas pipe and that opens and closes the second gas pipe.

Abstract: An air conditioner may include an outdoor unit including a compressor and an outdoor heat exchanger configured to heat exchange compressed refrigerant; an indoor unit having an air inlet and an air outlet and connected with the outdoor unit through a first pipe through which refrigerant discharged from the compressor flows and a second pipe through which refrigerant discharged from the outdoor heat exchanger flows; a blowing fan disposed in the indoor unit; a main heat exchanger configured to heat exchange air, which flows inside through the air inlet, and connected with the second pipe; a reheat exchanger disposed downstream of the main heat exchanger and connected with the first pipe; and a waste heat exchanger disposed upstream of the main heat exchanger and configured to heat-exchange air, which flows inside through the air inlet, and condensate water, which is produced at the main heat exchanger, with each other. Accordingly, air flowing inside through the air inlet is primarily cooled before exchanging heat through the main heat exchanger, whereby the cooling and dehumidifying performance is improved.

Abstract: An air conditioner includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, a converting unit, a first injection module, and a second injection module. The first injection module injects a portion of refrigerant flowing from the indoor heat exchanger to the outdoor heat exchanger to the compressor in a heating operation and supercools refrigerant flowing from the outdoor heat exchanger to the indoor heat exchanger in a cooling operation. The second injection module injects a portion of refrigerant flowing from the indoor heat exchanger to the outdoor heat exchanger to the compressor in the heating operation and injects refrigerant flowing from the outdoor heat exchanger to the indoor heat exchanger to the compressor in the cooling operation.
