PROBLEM TO BE SOLVED: To reduce operating power by lowering exhaust temperature by means of condensed water during cooling operation, and lowering condensation temperature. SOLUTION: The heat pump type air conditioner has inside a casing 1 a supply air passage 2 extending from a fresh air opening 2a to an air supply opening 2b and a return air passage 3 extending from a return air opening 3a to an exhaust opening 3b. The heat pump type air conditioner alternately carries out cooling and heating operations for a room to be air-conditioned, by causing refrigerant from a compressor 12 to circulate through a supply side heat exchanger 7 provided in the air supply passage 2 and a return side heat exchanger 10 provided in the return air passage 3, from the return side heat exchanger 10 to the supply side heat exchanger 7, or in the reverse order. The air conditioner includes a drain pan 19 provided under the supply side heat exchanger, a water supply means 21 for supplying water around the return side heat exchanger 10, and a water feed means 20 for feeding drain water collected in the drain pan 19 to the water supply means 21.
