PURPOSE:To store heat at a high efficiency and to reduce a heat dissipation loss incurred during conveyance of a capsule heat storage material, by a method wherein a fluid space partitioned by a net, a heat exchanger, and a fan are disposed in order in a heat insulated closed loop duct, an intake port for the open air is formed outside the fluid space, a conveyance duct is connected to the downstream of the fluid space, and opening of a damper between the fluid space and the conveyance duct causes shut off of a closed loop duct between the downstream side of the fluid space and the intake port. CONSTITUTION:Air heat-exchanged by means of a heat exchanger 1 when dampers 10 and 4 are closed is fed with the aid of a fan 2, and by circulation of the air through a closed loop duct 5, the air is heat-exchanged with a capsule heat storage material 6 floating in a fluid space 7 to store heat in the capsule heat storage material 6. After enough heat exchange with the capsule heat storage material 6 is performed, the dampers 4 and 10 are opened, and the damper 10 shuts off the closed loop duct 5 between the downstream side of the fluid space 7 and an intake port 8. By means of air discharged through the intake port 8, the capsule heat storage material 6 is carried to a given place through a conveyance duct 9, and heat-exchanges with air in the given place. |
