This article describes how the addition of stratified chilled water storage to the Cornell University campus 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. While chilled water storage is not appropriate for all chilled water systems, the experience at Cornell indicates that it can be very cost effective when favorable conditions exist. It should receive serious consideration by owners of large systems who are investigating alternatives for system expansion. The benefits of variable speed chiller operation were found to be considerable. It is hoped that this successful application will stimulate further interest in the development and application of variable speed drive chillers.
