Thermal Energy Storage (TES) Simple, proven, & accepted technology. Common on large facilities over 100,000 square feet. TES has not been available for smaller unitary equipment used in homes and small commercial. Ice Cycle is a new, proven TES technology for small to medium sized cooling applications.

Ice Cycle is a new, proven TES technology for small to medium sized cooling applications.

How Ice Cycle Performs IceCycle captures & stores air-conditioning energy during nighttime off-peak periods, when electricity is less expensive. Stored energy is used for air conditioning during the daytime peak periods, when electricity is much more expensive. IceCycle uses only 5 to 10% of conventional air conditioning energy during the peak period. IceCycle saves up to 20% of air conditioning operating costs through superior efficiency and by operating in cooler nighttime temperatures. IceCycle manages appliance load in peak periods (water heaters, pool pumps, etc).

Ice Cycle is Energy Efficient Green Technology Qualifies for Leadership in Energy Efficient Design (LEED) Certification. Shifts energy demand to more efficiently use current generation and transmission assets. Reduces the need for new power plants and new transmission lines. Lowers electric transmission congestion during peak periods. “ Night-time TES use reduces source energy consumption by 8 to 34 percent” (California Energy Commission Study). Lowers polluting emissions increasing current generation efficiency and lowering the need for new generation. Reduces potential blackouts and brownouts by lowering peak demand on the transmission grid, . Increases air conditioning energy efficiency and lowers energy cost. Manages the load of other appliances during peak periods. The cleanest and greenest energy is the energy we save.
