SOLUTION: An ejection nozzle 3 is provided on the side wall of a heat storage tank 1 and an antifreeze solution 2 is ejected from the ejection nozzle 3 into the heat storage tank 1. Ice particles 7 are produced through the direct contact heat exchange of water 6 with the antifreeze solution 2 which is then taken out from an outlet 9 at the lower part of the heat storage tank, passed through a circulation pump 4 and cooled by a refrigerating machine 5 before returned to the heat storage tank 1. On the other hand, ice particles 7 are deposited above the heat storage tank 1. Small spherical bodies 8 having specific gravity between those of the water 6 and the antifreeze solution 2 are floated on the separation interface between the water 6 and the antifreeze solution 2 after the heat exchange and continuous operation is performed by circulating the antifreeze solution 2 while floating the small spherical bodies 8.
