Embodiment Construction

[0022] The present invention includes the following steps:

[0023] Step 1: The water used for refrigeration is preliminarily cooled by the refrigeration cycle unit 2, and the temperature of the water after cooling is above 0°C;

[0024] Step 2: The above-mentioned cooled water is sprayed into the evaporative supercooling layer 4-1, and the ice making air processed by the air processing unit 3 is passed into the evaporative supercooling layer 4-1. The partial pressure of water vapor is lower than the saturated vapor pressure of the triple point of water 611.7Pa;

[0025] The third step: the above-mentioned water after evaporating the ice making layer 4-1 passes into the supercooling deicing layer 4-2, and is sprayed on the supercooling deicing device 4 in the supercooling deicing layer 4-2 3, produce a mixture of ice crystals and water;

[0026] Step 4: While completing the above third step, the ice making air from the evaporated supercooling layer 4-1 is passed into the supercool...

Abstract

The invention relates to a method for producing fluid ice using supercooled water and a device thereof, specifically to a double-layer evaporative method for producing fluid ice using supercooled water and a device thereof. The invention comprises the following steps of: primarily cooling the water for producing ice via a refrigerating cycle unit, sprinkling the cooled water for producing ice on an evaporation supercooled layer, and introducing the treated air for producing ice into the evaporation supercooled layer, wherein the water vapor partial pressure is lower than water three-phase saturated vapor pressure 611.7Pa; introducing the treated water into a supercooling relieving and ice producing layer and sprinkling the treated water on a supercooling relieving device for generate a mixture of ice crystal and water; introducing the ice for producing ice from the evaporation supercooled layer to the supercooling relieving and ice producing layer to keep relatively low surrounding temperature of the second layer, and returning the ice for producing ice to an air treatment unit; separating the mixture of ice crystal and water via a ice and water separator to obtain fluid ice; and returning the separated water to a water tank unit. The invention has the advantages of low energy loss, high ice producing efficiency and no ice blockage.

Description

Technical field [0001] The invention relates to a method and a device for preparing fluid ice by using supercooled water. Background technique [0002] With the emergence of energy shortages, the energy consumption of air-conditioning systems caused by the widespread use of refrigeration and air-conditioning equipment has aroused widespread concern in the current society. Energy saving has become an urgent need under the new situation in the refrigeration field. my country has also proposed sustainable development. Country-building strategy. Ice storage is of great significance as an energy-saving design idea, and fluid ice has become the first choice for ice storage due to its good thermal characteristics. [0003] Compared with the traditional static ice making method, the existing ice storage air conditioner adopts supercooled water to dynamically produce fluid ice. The heat transfer resistance between the refrigerant and the water is smaller, and it will not change with the a...
