Ice storage air conditioning

OverviewEarly ice storage, shipment, and productionAir conditioningCombustion gas turbine air inlet coolingSee also

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. Alternative power sources such as solar can also use the technology to store energy for later use. This is practical because of water''s large heat of fusion: one metric ton of water (one cubic metre) can store 334 megajoules (MJ…
