Ice Based Energy Storage Integration with Solar PV Power Plants for Cooling Energy

This paper gives aspects of the design of Cooling Thermal Energy Storage (CTES) for cold storage refrigeration and building air conditioning plants, powered/integrated through Solar Photo Voltaic (SPV) power. Ice based CTES are useful when there is mismatch between the availability of the energy source (grid tied centralized system or roof top decentralized system) and the air conditioning/ refrigeration application period. In both grid power with time of the day metering or SPV powered systems in integrated as well as in decentralized SPV, the source-load mismatch is handled through an ice storage system. The ice storage system not only helps with operation under decoupled source-load environment but gives the benefits of reduction in maximum output power, average power and energy consumption by 20-40 % as compared to conventional systems in centralized as well as decentralized environments.
