Thermal Ice Storage
The thermal ice storage provides a cap on peak cooling demand. At times of day when the existing cooling technology is not fully utilised, the storage is charged. The stored energy is fed back into the system when required. In this way, the refrigeration technology can be aligned with the average demand and dimensioned more economically.

Ice storage air conditioning
Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. [1] Alternative power sources such as solar can also use the technology to store energy for later use. [1] This is practical because of water''s large heat of fusion: one

Ice energy store
The ice storage is integrated into the base load, and the refrigeration machines cover the peak loads. The ice storage system allows 6,000 kWh of energy to be stored taking into account the base load. This represents 60% of the daily requirement. In spring and autumn, it can cover 100% of the daily requirement.

Currently, twenty one phases, including both crystalline and amorphous ices, have been observed at various densities.
To Cool Buildings More Efficiently, We Turn To An Ancient Technology: Ice
Buildings can also create and store ice at night that''s used the following day to cool buildings (instead of drinks). The main benefit of ice storage is shifting electric consumption to off-peak hours and reducing peak energy demand. Ice storage takes advantage of cheaper off-peak electric rates and significantly reduces cooling costs.
