Method for increasing supercooling degree of water and supercooling device adopting method

Abstract

The invention discloses a method for increasing super cooling degree of water and an application thereof and a device adopting the method. An alternating magnetic field is used for exerting effect on super cooled water, which leads to the vibration of hydrones, thereby preventing the super cooled water from icing up at certain temperature. The method comprises the following steps: a magetostatic field and the alternating magnetic field are superimposed to generate a single-way magnetic field; wherein the magetostatic field is between 1 GS and 20,000 GS, and the alternating magnetic field changes alternatively by taking the value of the magetostatic field as a reference, and the change amplitude ranges from 5 percent to 15 percent of the value of the magetostatic field; the alternating magnetic field exerts effect on the hydrones and leads to the regular magnetic moment arrangement in the hydrones due to electron spinning so as to be beneficial to the motion of electrons in the hydrones, improve thermal conduction performance and lead to fast thermal conduction in the water; a magnetic field is applied during the cooling of water, which can enhance the thermal motion of the hydrones; and after being in a super cooled state, the hydrones are further cooled to increase the super cooling degree of the water.

Description

technical field [0001] The invention relates to a method for increasing water supercooling degree, its application and a device using the method. Background technique [0002] Dynamic ice making with supercooled water is a new ice making method. Compared with the traditional static ice making method, it has high heat transfer efficiency and low energy consumption; while the dynamic ice (ice slurry) produced can be directly transported by a pump, which reduces the size of the system pipeline. The problem existing in this method at present is how to increase the subcooling degree of the water, thereby preventing the water from freezing in the subcooler and causing ice blockage. Existing methods for increasing the degree of subcooling include ultrasonic method (ZL200520066480.8), surface coating method (00103341.7), etc., but cannot control the degree of supercooling of water well. Contents of the invention [0003] The object of the present invention is to solve the above-...
