PURPOSE:To speed up the rise time of air conditioned cooling operation by a method wherein the heat exchange between ice and cold water is accelerated and consequently the extraction of cold heat is made possible, even when a cold heat accumulating tank is full of ice, by forming a passage for cold water through the forced heating and melting of the ice in response to the result of the detection of the state of the ice accumulated in the cold heat accumulating tank. CONSTITUTION:A sheathed heating wire 10 is arranged vertically in zigzags along a flowing water passage 9 between heat pipes 6 and 6 and both ends of the wire 10 are led outside a tank 3 so as to be connected through a switch 11 to a power supply 12. A cold water circulating circuit A for cooling, through which cold water 8 is circulated, is arranged at the inlet side and outlet side of the flowing water passage 9 of a cold heat accumulating tank 3. A circulating pump 13, which serves both for flowing the cold water 8 during cold heat accumulation and for extracting the cold heat during air conditioning, a flow sensor 14 to detect the circulating flow rate of the cold water 8, and a valve 15a are provided in the cold water circulating circuit A and electrically connected to a control board 16. |
