Description

When a chilled water plant is being extended, it may save three ways to use a storage reservoir rather than another chiller.

When a capacity module of 1,000 tons or greater is involved, the first cost of chilled water storage of equivalent capacity may be as little as half the cost of a new chiller.

When the proposed incremental chiller has electric drive, storage can save in the cost of electric demand. This derives from regenerating storage at night, off peak, by extending the operation of existing chillers. Savings of from 50 to 90% can result in energy cost.

The third saving takes place at the electric utility, where no new capacity need be provided for the incremental chilled water requirement. It is the cost of expanding utility capacity which underlies part of the need for increased electric rates today.

This paper will use slides to show how Thermal Storage Saves and saves and saves.
