Avoiding Stratified Chilled Water TES Problems. - Free

Thermal energy storage (TES) is an effective means of shifting cooling electrical load from peak to off-peak electrical rates or load-leveling combined heat and power plants to provide energy cost savings. Chilled water is the most common form of TES for large facilities, using concrete or steel tanks to store chilled water.
