Abstract

Operation of a 150-tin chill aquifer thermal energy storage (ATES) system used to air-condition the University of Alabama Student Recreation Center has been monitored for several years. The ATES system chills water in the winter, stores it in a water-table aquifer, and recovers cold water for summer air-conditioning. A program has been implemented to reduce losses of chilled water resulting from natural aquifer flow. Analysis of data to determine the effectiveness of flow control measures is reported. Demonstration of improved overall energy efficiency (coefficient of performance or COP) requires further performance monitoring, but flow control measures clearly result in lowered water recovery temperatures, thus improving dehumidification
