The stirring blade 3a uses four paddle blades having an inclination of 45 ° or less as described above, and is rotated so that a force is applied downward. By this rotation, the ice near the root of the blade 3a moves outward from the central portion. Further, the ice from the lower part of the stirring blade 3a in the ice water chamber 21 to the bottom of the storage tank 1 is prevented from rotating integrally with the ice around the stirring blade by the baffle plate 4, while the ice is moved upward by its own buoyancy.

It is sent to the load 23 through the ice water carrier pipe 8a by the pump 19a. When the ice in the ice water chamber 21 floats, ice blocks are formed due to the lack of the aqueous solution that suppresses the freezing of the condensed water and the coalescence of the ice. The cold heat component of this ice block is not effectively used as ice water transport, and when the ice block is crushed and supplied to the load 23 side, it is caught in the flow passage gap of the pump or the heat exchanger, and the ice water transport becomes impossible. Therefore Oite to such embodiments, a partition plate 5 provided inside the storage tank 1, since the partitions the upper ice water chamber 21 and the expansion tank 6, to force the upper portion of the ice by the partition plate 5 Submersion ensures that the liquid 22 is above the ice.

まり攪拌機３の駆動動力が大幅に低減される。In such an embodiment, the stirring blade 3a is immersed in the upper portion of the ice water chamber and rotated, so that the ice in the central portion of the blade is only moved to the outer peripheral portion where the ice water extraction conduit 8 is opened. The ice in the ice water chamber 21 moves to the upper part of the stirring blade 3a by its buoyancy. That is, by rotating the stirring blade 3a in ice water, the ice water in the ice water chamber 21 flows toward the stirring blade 3a at the upper side in a piston-like manner, so that the stirring machine 3 stirs the storage tank 1. Instead, it is only necessary to make the minimum necessary flow of ice water, so the power for taking out ice water, that is, the drive power of the stirrer 3 is greatly reduced.

The ice water taken out to the ice water transfer pipe 8a as described above is transferred I
After the measurement adjustment described later is performed by the PF measuring device 19,
It is sent to the load 23 and outputs the required cold heat. The ice water or water (hereinafter referred to as ice water) returned from the load 23 is
It flows into the outer donut header 10b at the bottom of the storage tank 1 through the return pipes 42 and 42a.
