To provide a heat accumulation air conditioning system capable of promoting heat radiation by ventilation, increasing the heat accumulation quantity, and controlling the heat radiation.
An air conditioner 8 connected to a heat source machine 7 connected to a heat accumulation pipe 6 buried in a building skeleton 5 is allowed to communicate with a space part 4 provided between the building skeleton 5 and a floor 3 through a communicating duct 15 extending vertically within a room. The communicating duct 14 comprises a duct air feed port 15 to be provided within each room 1 and an underfloor ventilation damper 17 provided on a space part-side communicating port 16 to feed the heat accumulated in the building skeleton 5 by the feed air flow sent to the space part 4 through the ventilation duct 14. According to this, a heat accumulation air conditioning system capable of promoting heat radiation by ventilation and controlling the heat radiation can be obtained.
