AN-92-14-1 -- Combined Chilled Water Thermal Energy Storage and Fire Protection Storage PDF

Notes trends towards thermal storage as energy supply companies struggle to meet consumer energy needs without constructing new power plants. At the same time the need for reliable water supplies for fire protection service can be expected to grow, with the requirement for sprinkler systems now imposed on most new construction. States these trends create an obvious opportunity for combined technology - the use of chilled water thermal storage for fire protection service. Addresses the issues involved in integrating these systems and uses a recently completed truck assembly plant in South Carolina to illustrate the concept. First discusses general considerations. Describes the parameters defining the system design. Details system economics. Explains the importance of water treatment. Illustrates schematically and describes the chilled water storage system and lists the advantages of thermal storage over direct refrigeration plant. Notes estimated energy cost savings at 263 000 per year, giving a seven month payback period. States that actual system operations have proved the overall effectiveness of the integrated design.
