Internal Melt Ice-on-Coil (IMIOC)
There are a number of manufacturers and installers of this type of technology. The market leader Calmac is highlighted.
CALMAC Mfg. Corp. of Fair Lawn, New Jersey, with over 3,300 Cool Storage installations around the world specializes in ice-based energy storage. With their Ice Storage technology you receive the same comfort and reliability as you would expect from your cooling systems but with an added safety factor, reduction in cooling costs and with less impact on the environment.
IceBank® systems utilize a standard chiller to produce ice during the night and store it in modular IceBank® energy storage tanks. The stored ice provides cooling the following day to meet the building's air- conditioning requirement.
- Tanks contain a spiral-wound, polyethylene-tube heat exchanger surrounded with water
- IceBank tank design stores more energy in less space than competing brands
- Tanks are available in a variety of sizes ranging from 45 to over 500 ton-hours
- You can choose from full- and partial- load systems
- All tanks are modular, have no moving parts, are made of polyethylene and are well insulated
- Installation is fast, simple
- Tanks can be sited in a basement, on roofs, inside, outside or even buried
"Excess electric capacity," according to the Brattle Group, "has shrunk to a level barely within the planning toleration of the industry." This grid reliability issue along with sustainable design and the goal to be more energy independent has driven changes in California's Title 24 to encourage load shifting technologies and has reignited the thermal energy storage industry. Owners, architects, and engineers are turning to hybrid cooling systems that use energy storage and are moving away from the "just in time production" of conventional comfort cooling systems to take advantage of cleaner cheaper off peak energy and renewable energy.
