Design and Construction of an Ice-in-Tank Diurnal Ice Storage for the PX Building at Fort Stewart, GA

Abstract : Diurnal cold storage cooling systems may be effective tools for reducing peak electrical demand at Army installations. Ice, water, or eutectic salts can be used to store refrigeration produced during offpeak hours. Then, during peak load periods, the stored cold can be used to cool a facility. Such a reduction in the peak electrical demand can result in substantial savings in utility bills throughout the year. However, there is a lack of standard design guidance on these systems for Army engineers. As a first step toward remedying that situation, a demonstration ice in tank diurnal ice storage (DIS) cooling system was designed and installed--using standard engineering practices--at Fort Steward, GA. Although the concept of cold storage is new, it can be implemented using familiar engineering procedures. This report documents the design and installation of the ice-in-tank system. The results of performance and operational testing will appear in a future technical report. Keywords: Energy storage, Air conditioning system.
