PROBLEM TO BE SOLVED: To provide a heat pump type air conditioning device having a defrosting structure capable of performing quick defrosting without being affected by a circumferential air temperature and without distributing the cold air into an air-conditioned room. SOLUTION: This heat pump type air conditioning device which is provided with a supply air flow channel 4 from an outside air inlet 2 to an air supply opening 3, and a return air flow channel 7 from an air return opening 5 of the air-conditioned room to an exhaust opening 6 in a casing 1, and in which a refrigerant from a compressor 14 is switched to an air supply side heat exchanger 9 disposed in the supply air flow channel 4 and a return air side heat exchanger 12 disposed in the return air flow channel 7 to perform a cooling operation and a heating operation, further includes a drain pan 20a disposed at a lower part of the supply air side heat exchanger 9, a water storage tank 21 for storing the water, and a water supplying means 24 for supplying the water stored in the water storage tank 21 to the circumference of the return air side heat exchanger 12 in the cooling operation for removing frost generated on the return air side heat exchanger 12.
