Chairperson and program abstract: Guy Frankenfield - Effective Design and Operation of Thermal Energy Storage Systems in Hot and Humid Climates Thermal energy storage (TES) systems have been used effectively for the over three decades. This seminar highlights the two most common TES systems (chilled water and ice) with case studies of systems in Florida. The case studies include how TES systems provide value in a hot and humid climate.
Presentation 1: John Andrepont - District Cooling Systems with Chilled Water TES in Humid Environments District cooling (DC) systems are in operation and growing in use around the world, including many in humid environments. Often, sensible heat chilled water (CHW) thermal energy storage (TES) is employed to technical and economic advantage in such DC systems. CHW TES often reduces operating electric costs, but also often reduces net capital cost through its role as low unit cost, peaking capacity. Numerous examples of DC systems using CHW TES are cited from installations in hot-humid climates in Malaysia, the Arabian Gulf Coast, Brazil, the Texas Gulf Coast and throughout Florida. Summary data is presented for each example and technical and economic details provided for a large installation in Orlando, Florida.
Presentation 2: Robert Wegmann - Ice Storage Systems at Schools in Florida This presentation will highlight several schools where ice storage systems have been used in school chiller plants in central florida. These systems utilize glycol static ice systems, both full and partial thermal storage designs, both air and water cooled chillers, and wide supply water delta T’s for reduced pumping requirements. In some cases utility rebates were available, in some cases they were not. System life cycle costs and LEED considerations will be addressed.
