Embodiment Construction

[0045] The supercooling apparatus and the method of operation thereof according to the present invention will now be described in detail with reference to the accompanying drawings.

[0046] Figure 5 It is a conceptual diagram showing the production of semi-melted snow according to the present invention. refer to Figure 5 , between the electrodes 40, a liquid 41, that is, an object of supercooling, is arranged. In a state where the cool air 42 is supplied, an electric field is applied to the liquid 41 by using an AC power source. Thus, the liquid does not freeze but is supercooled below its phase transition temperature (eg, water at 0°C below 1 atmosphere). An energy supply such as an electric field causes the water molecules to vibrate, rotate and translate continuously, and break the hydrogen bonding of the water. As a result, water composed of oxygen and hydrogen does not freeze.

[0047] When an external force is applied to the subcooled liquid by the phase converte...

Abstract

The invention discloses a undercooling device and a method for operating this undercooling device, the under cooling device and control method thereof can be used for terminating undercooling state in undercooling space and preventing energy exposure of electrical field. The undercooling device comprises: space cooled by cooling air, used for keeping the contents in undercooling state via supplying energy preventing inner contents from being converted into solid phase; a sensing unit for sensing undercooling termination of the space or the contents; and a heater combined with the sensing unit for providing heat to the space or the contents.

Description

technical field [0001] The present invention relates to a subcooling device and a method of operating the subcooling device, and more particularly, to a subcooling device capable of solving the supercooling release of the subcooling space and preventing the exposure of energy such as an electric field and operating the subcooling device method of the device. Background technique [0002] Subcooling means that a liquid such as water does not turn into a solid but remains in a high temperature phase, ie a liquid phase even below the phase transition temperature at which it turns into a solid. Water droplets can be supercooled in their natural state. In addition, water or beverages can be incidentally supercooled in ordinary refrigerators. A freezing method disclosed in Japanese Patent Laid-Open Publication S59-151834 and a freezing method and refrigerator disclosed in Japanese Patent Laid-Open Publication No. 2001-086967 apply the supercooling principle to the refrigerator. ...
