<p>A cold storage cell in the form of a hollow plate or shell constructed of material having high heat conductivity and filled with a eutectic solution having a freezing point substantially below the freezing point of water in order to enable the latent heat of fusion of the freezable solution to be utilized at a lower temperature for cooling and freezing of various food items or non-food items. The cold storage cell is closed and filled with a solution of ethylene glycol and water propylene glycol and water or a brine solution in which the ratio of the glycol to water may be varied depending upon the freezing temperature desired. The cold storage cells are used in various types of refrigeration systems such as the type employing an air blast to cool the cold storage cells from ambient temperature to a temperature where the freezable solution is frozen which cooling process can take a relatively long period of time depending upon the air temperature, the amount of freezable liquid solution in the cells, the refrigeration system capacity, the number of the cells and the like so that all of the cells will be cooled sufficiently to remove the latent heat of fusion of the freezable solution after which the refrigeration system is ready for loading with items to be cooled. As the items or products are loaded into the refrigeration machine, the warmer items or products will be cooled by the cells as the refrigeration stored in the cells is released with the refrigeration system continuing to operate at its capacity which may be at a capacity less than the refrigeration released by the cells or at a capacity sufficient to replace the refrigeration released by the cells to the items or products.</p> |
