Ice batteries have been used since absorption chillers first made ice commercially available 150 years ago, before the invention of the electric light bulb.

The cooling would be performed with an absorption chiller.

Efficient absorption chillers require water of at least 190 F (88 C).

For 150 years, absorption chillers have been used to make ice (before the electric light bulb was invented).

Cooling is achieved by passing the waste heat to an absorption chiller.

The solar energy heats a fluid that provides heat to the generator of an absorption chiller and is recirculated back to the collectors.

The hot water produced by the plant can also be used to supply thermal energy and air conditioning (via an absorption chiller) to the surrounding area.

The main company makes absorption chillers used for large air conditioning systems.

Byproduct heat at moderate temperatures (100 to 180 C) can also be used in absorption chillers for cooling.

In extremely sunny climates, solar energy has been used to operate absorption chillers.
