PROBLEM TO BE SOLVED: To continuously make ice without influence of an increase in an ice storage IPF or a generating state of an ice by generating a low-temperature air, sending the air to an icemaker for generating an ice by bringing the air into direct contact with water, and conveying the ice generated by the ice maker into a heat storage tank. SOLUTION: An air cooler 4 is constituted of an indirect cooling type with a brine, an air cooler of a refrigerant direct expansion type or the like or an air cycle or the like having an air expansion unit to generate a low- temperature air for cooling to 0 deg.C or lower. A cold water tube 7 connects a bottom of a heat storage tank 1 to a reservoir 11 of an icemaker 10, and a cold water pump 3 provided at the tube 7 sends a cold water (water for icemaking) in the tank 1 to the reservoir 11. An ice conveying tube 8 for connecting an outlet chamber 15 to the tank 1 introduces the ice generated by the icemaker 10 to the tank 1 through the tube 8. Thus, the ice generated by the icemaking is mainly gathered to an upper portion in the tank 1 by its buoyancy. |
