Thermal Energy Storage (TES) used for Off-Peak Cooling of buildings, has a long history around the world with over 7,000 commercial installations in 40 countries. By storing cooling at night, in the form of ice or chilled water, and using it during the day to cool the buildings, major reductions in on-peak electric demand and energy costs are realized. This technical seminar will demonstrate the basic types of TES systems, how energy storage on both the Grid side and Building side of the meter will be covered along with their respective applications and the myths surrounding Ice-based TES. The speakers also share their experience on design, installation and commissioning of Ice Thermal Storage System.
