Chilled Water Storage
Chilled water storage is most common on very large projects (typically over 500,000 sq ft) where ample space is available. The steel or oncrete tank(s) can be located either above- or below-ground. In some cases, the stored water can serve to provide some or all the fire protection water storage. The complexities of assuring thermal stratification make chilled water storage more attractive where the storage tank is very large (and deeper than about 20 feet).
Adding chilled water storage is also an option for an existing facility to meet immediate growth needs while postponing new chiller acquisitions.
