Claim 11:
12. An air conditioner, comprising:
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, wherein the indoor unit is connected to the outdoor unit by 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 flowing into the indoor unit through the air inlet, wherein the main heat exchanger is connected with the second pipe;
a reheat exchanger disposed downstream of the main heat exchanger and connected with the first pipe;
a waste heat exchanger disposed upstream of the main heat exchanger, wherein the waste heat exchanger is configured to heat-exchange the air flowing into the indoor unit through the air inlet and condensate water which is produced at the main heat exchanger; and
a drain that supplies the condensate water produced at the main heat exchanger to the waste heat exchanger, wherein the drain includes a drain pan in which the condensate water is collected, wherein the main heat exchanger, the reheat exchanger, and the waste heat exchanger are disposed such that at least a portion of each is positioned inside of the drain pan, and wherein the drain further includes a pump, and wherein the waste heat exchanger is disposed between the main heat exchanger and the pump.
