REVIEW ON SUSTAINABLE THERMAL-ENERGY STORAGE TECHNOLOGIES, PART-II - COOL THERMAL STORAGE

This paper describes the inherent pros and cons of the two common (i.e . chilled water and ice storage) commercially available thermal energy storage (TES) technologies for off-peak air conditioning applications . Case studies on cool thermal storage have demonstrated not only savi ngs in energy and other operation and maintenance costs but also signi ficant savings in initial capital costs. This paper also examines the use of cool thermal storage equipment for gas turbine inlet air coolin g, which can positively enhance its efficiency. it has been observed t hat the application of TES has been predominantly in North America. Ho wever, in the mid-1990 s, applications have begun to appear in Asia, A ustralia, Europe and South America. Finally, prospects of TES technolo gies for electric load management in Saudi Arabia are also elucidated. (C) 1998 Elsevier Science Ltd. All rights reserved.
