Claim 0:
1. 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 second 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
a pump that discharges the condensate water collected in the drain pans wherein the main heat exchanger, the reheat exchanger, and the waste heat exchanger are each disposed on an upper side of the drain pan; and

wherein the waste heat exchanger is disposed such that at least a portion thereof is positioned inside of the drain pan.
