An ice pond is a large volume of ice or snow produced by natural winter freezing. The ice is then used for cooling or air conditioning. Before refrigeration was common, ice ponds were mined by ice companies, with product transported to consumers and food businesses through much of the year. Refrigeration technology replaced this technology.
Cooling pond of the Balakovo Nuclear Power Plant in Russia. A cooling pond is a man-made body of water primarily formed for the purpose of cooling heated water or to store and supply cooling water to a nearby power plant or industrial facility such as a petroleum refinery, pulp and paper mill, chemical plant, steel mill or smelter.
These methods either heat the structures in the water to prevent frazil ice adhesion or heat the water to prevent frazil ice from forming in the first place. When heating the structure, it must be heated to a temperature above freezing. Electrical resistance heaters have been found to work well, but these have potential safety problems.
Supercooling is the cooling of a liquid below its freezing point without it becoming solid. Freezing point depression is when a solution can be cooled below the freezing point of the corresponding pure liquid due to the presence of the solute; an example of this is the freezing point depression that occurs when salt is added to pure water.
[38] [39] For example, air conditioning can be provided more economically by using low-cost electricity at night to freeze water into ice, then using the cooling capacity of ice in the afternoon to reduce the electricity needed to handle air conditioning demands. Thermal energy storage using ice makes use of the large heat of fusion of water ...
