Ice Storage Sprayed WG System.

Thermal Energy Storage is often used in association with centralized chiller plants designed for large buildings or District Cooling, and it is an effective method for shifting a part of the air-conditioning electricity demand charge and consumption from peak to off-peak periods.

For such applications, the Ice Containers are dry stacked in large atmospheric tanks of steel or concrete. The heat exchange cycles are effected by using a water glycol coolant sprayed over the spherical containers.

For charging, the coolant - cooled by chillers to below 0°C (32°F) - passes around the containers making ice inside.
For discharging, the coolant - heated by the user to over 0°C (32°F) - passes around the containers melting the ice inside. 06/01/06
