The resulting chilled water is used to meet the cooling demand. Internal melt ice-on-coil storage systems use a secondary coolant as the charging and discharging heat transfer fluid, circulating it through tubes or coils submerged in water-filled tanks. To build ice, a chiller cools the coolant and ice forms on the outside of the tubes.

The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commerciall…
