ASSESSMENT OF ENERGY STORAGE TECHNOLOGIES AND SYSTEMSnPHASE I:ELECTRIC STORAGE HEATING,nSTORAGE AIR CONDITIONING, AND STORAGE HOT WATER HEATERS

摘要

This study analyzes the commercial feasibility of thermal energy storage (TES) in buildings;TES applications examined in¬clude storage electric (resistance) heating, storage air condi¬tioning, and storage hot water heating.nA system model, SIMSTOR, is employed to simulate TES-related effects upon daily and annual utility load profiles and to com¬pare utility fuel and capital cost savings with TES-system costs. Case-study analyses of TES applications for a representative set of utility service areas indicate that several already- and near-commercial TES systems are cost-effective. Alternative strategies to commercialize these systems are examined and the preferred strategies are identified.
