Résumé

Thermal energy storage (TES) is an effective means of shifting cooling electrical load from peak to off-peak electrical rates. Chilled water is the most common form of TES, using concrete or steel tanks to store chilled water at 39°F (4°C), which is the temperature at which water density is highest, encouraging stratification within the tank. Under normal conditions, a chilled water TES tank is always filled with water. During discharge, cold water is pumped from the bottom of the tank, while an equal amount of warm return water is returned to the top of the tank. Due to the increased density of colder water, a stable stratification of layers of water can be obtained.
