Inflow into the hollow formed by the front plate (24c) and the rear plate (24d) through, and the brine introduced into the hollow portion freezes the water stored in the ice storage tank 10, and then the outlet pipe portion ( The cycle flowing back into the refrigerator 22 through 24b) is repeated until the water in the ice storage tank 10 is completely frozen. Second, the anti-freeze cycle 30 for thawing the ice E partially frozen in the ice storage tank 10 to form a channel, the antifreeze filled in the conduit by the drive of the anti-freeze circulation pump 34 for thawing The antifreeze thawing plate portion which is introduced into the fan coil unit 32 and the antifreeze flowed into the fan coil unit 32 is heat-exchanged with the hot air in the room to increase the temperature, and then mounted in the ice storage tank 10. (33) flows in, and the antifreeze flowing into the thaw antifreeze ice plate 33 is heat-exchanged with the frozen ice (E) of the ice storage tank 10 and then flows back to the antifreeze circulating pump 34 for thawing . This process is repeated until the ice formed around the ice-free antifreeze thawing plate 33 is melted by heat exchange between the ice E frozen in the thawing antifreeze thawing plate 33 and the antifreeze to form a water channel. At this time, in the antifreeze expansion tank 31 for thawing, the volume change of the antifreeze due to the temperature change in the pipeline is processed. Third, the cold water cycle 40 that cools the room by circulating the thawed cold water F flowing through the water channel formed by the ice E partially frozen in the ice heat storage tank 10 is the ice heat storage tank 10. When the gate valve 45 installed in the conduit interlocked with the lower part of the c) is opened and the cold water circulation pump 41 is driven, the thawed cold water F is indoors via the gate valve 45 and the check valve 46. Cold water flows into the installed air conditioner 43, and the cold water introduced into the air conditioner 43 flows into an external hot air and then flows into the cold water auxiliary tank 44, into the cold water auxiliary tank 44. The inflow rate is adjusted to match the water level of the ice storage tank 10 by the control valve 44a after the temperature rises, and then flows back into the ice storage tank 10 through a pipe communicating with the upper portion of the ice storage tank 10. Repeat the process. At this time, in the cold water expansion tank 42, the volume change of the cold water by the temperature change in the pipeline is processed. In addition, when the operation is stopped, the water flowing into the cold water auxiliary tank 44 closes the control valve 44a by the rise of the float 44b so that the cold water cannot be introduced, and the cold water circulation pump at the bottom of the ice storage tank 10 is stopped. On the (41) side there is a check valve 46 is opened when the cold water outflow, but when the inflow of cold water check valve 46 is automatically closed because the cold water can not flow into the ice storage tank (10) The water level does not rise above a certain level.
