Abstract: A supercooling release material, which releases a supercooled state of a cold storage material including one or more types of alkylammonium halide aqueous solutions that generate a hydrate by being cooled to a hydrate generation temperature or lower, includes: an alkylammonium ion included in the cold storage material; and a metal halide ion which has, as a constituent element, a halogen element included in the cold storage material. The supercooled state of the cold storage material can be reliably released by using the supercooling release material having such a configuration.

Abstract: A method is disclosed for freezing supercooled water, which method includes the steps of (1-1) filling said supercooled water in a sealed container, reducing pressure of said supercooled water to generate bubbles from the supercooled water, mixing said generated bubbles in the supercooled water, or (1-2) filling said supercooled water in a sealed container with a bubble-mixing inlet, reducing pressure of the supercooled water to mix bubbles into the supercooled water from outside of the container through the bubble mixing inlet, or (1-3) filling said supercooled water in the sealed container with the bubble-mixing inlet, introducing bubbles into the supercooled water from outside the container through the bubble-mixing inlet under pressure, mixing the bubbles into the supercooled water, (2) simultaneously repeating expansion, compression, disruption, clustering and disappearance of the bubbles mixed into the supercooled water and (3) thereby freezing the supercooled water by vigorously oscillating gas-liquid

Abstract: A method for freezing a supercooled liquid, includes the steps of forming a liquid phase of a supercooled liquid and a gas phase adjacent to the liquid phase in a container, vibrating a gas-liquid interface formed by said liquid phase and the gas phase by applying vibration upon the gas-liquid interface and/or a vicinity thereof along the gas-liquid interface, forming splashed waves of the supercooled liquid, scattering liquid drops of the supercooled liquid, crashing the liquid drops upon a portion of an inner wall of the container where the gas phase is located, mixing resulting liquid drops and bubbles into the supercooled liquid through the gas-liquid interface, subjecting said bubbles mixed in the supercooled liquid to expansion, compression, disruption, clustering and disappearance, thereby vigorously oscillating the gas-liquid interface and freezing the supercooled liquid.

Abstract: The object of this invention is to provide a comparatively small freezing device capable of freezing supercooled water instantly at any desired time and place even though the water is at a poorly supercooled state which is resistive to freezing, by actively resolving the supercooled state. The object is achieved by providing a freezing device comprising a cylinder 1 to receive supercooled water, at least one piston 2, 3 to fit liquid-tight to the cylinder to move therein, which, by moving through the cylinder, introduces supercooled water into the cylinder, gives a mechanical impact to the supercooled water enclosed in the cylinder, and expels water in which the supercooled state has been resolved in the presence of impact, out of the cylinder, and a water inlet 1a and outlet 1b to be connected to at least one of the cylinder and piston in such a way as to allow their opening and closing.
