Ice Thermal Storage Design

Partial storage design strategies with a full storage configuration a building s entire cooling load is shifted to off peak hours.

Ice thermal storage design. Evapco s team of ice coil professionals is ready to provide personal attention and technical support to custom match the most efficient ice coil in the industry with your system needs. Ice thermal storage products store cooling while shifting energy usage to off peak hours dramatically reducing cooling costs and stress on the electrical grid. Ice storage air conditioning is the process of using ice for thermal energy storage this is practical because of water s large heat of fusion. Unfortunately these energies have no natural storage mechanism.

The technology of ice thermal storage application for air conditioning system is not new and it is not difficult. Actually the system design requires only the very basic technical know how and engineering practices. Ice was originally obtained from mountains or cut from frozen lakes and transported to cities for use as a coolant. Many basic principles required for ice thermal storage system design are already outlined in the.

Ice or chilled water. The chiller only runs during off peak nighttime hours in order to store ice for use the following day. Emergency use chilled water modular ice 1. We ll cover a bit of theory and application then demonstrate the design steps for a small ice storage system from layout.

Environmentally friendly ice thermal storage reduces greenhouse gas emissions and can qualify for leed certification credits. Usage examples are the balancing of energy demand between daytime and nighttime storing summer. One metric ton of water one cubic metre can store 334 megajoules mj 317 000 btu of energy equivalent to 93 kwh 26 4 ton hours. Bac has thousands of successful installations.

Thermal storage incremental cost thermal storage installed ton hours cost per ton hour 1. Thermal storage is the easiest way to restore this critical component of fossil fuel based energy. Thermal energy storage tes is achieved with widely differing technologies depending on the specific technology it allows excess thermal energy to be stored and used hours days months later at scales ranging from the individual process building multiuser building district town or region. Design and application the grid of the future will incorporate a higher percentage of renewable energy like wind and pv solar.

The size and quantity of ice coils will vary based capacity requirements layout and system design.
