Abstract

The addition of stratified chilled water storage to the Cornell chilled water system has increased its capacity and efficiency and reduced its operating costs for less than the cost of a conventional chilled water plant expansion. The other new component of the storage facility - two variable speed drive thermal storage transfer pumps - saved energy by allowing adjustment to the lower system head without throttling. The first-year operating cost savings exceeded $300,000 - $235,000 due to demand shift and time of use savings, and the remainder from the impact of thermal storage on overall system performance.
