Summary

Describes how Arizona State University expanded its chiller plant capacity by placing a thermal storage system under a baseball field. The project added 54,000 ton hours of cooling capacity with no loss of land or building space. Energy savings of $ 1.1 million a year were realised, yielding a payback of 3.75 years. Presents a schematic of the thermal energy storage system, comprising six underground thermal storage tanks holding 5.5 million gallons, and the pipe-and-pump gallery connecting it to the 18,000 ton plant located 0,4 kilometers away. Automatic valves allow tanks to be filled and drained sequentially. Summarises in a table monthly performance results for 1991.
