To provide a heat pump hot-water supply air conditioner capable of performing the air conditioning while supplying the hot water.
A hot water supply tank 5 and a cold heat storage tank 15 are connected with a heat pump unit 4 in parallel. A boiling-up circulation passage 10 is formed to boil up the hot water in the hot water storage tank 5. Further a circulation passage 16 for cold heat storage is formed to boil up and cool the hot water in the cold heat storage tank 15. Further a circulation passage 17 for radiating the stored cold heat is formed to circulate the hot water or cold water in the cold heat storage tank 15 to a stored cold heat radiation panel 19. In the hot water storage heating, the heat pump unit 4, the boiling-up circulation passage 10 and the circulation passage 16 for cold heat storage are operated to store the hot water respectively in the hot water storage tank 5 and the cold heat storage tank 15. In the hot water storage cooling, a three-way valve 13 is switched to a side of the circulation passage 16 for cold heat storage first, then a four-way valve 23 of the heat pump unit 4 is reversed to perform the reversed-cycle operation, and the circulation passage 16 for cold heat storage is driven to store the cold water in the cold heat storage tank 15.
