Abstract
Abstract : Approximately one-third of all energy consumption and two-thirds of total energy expenditures at Department of Defense fixed facilities are electricity related. Electrical energy costs can be reduced by conserving electrical energy or by replacing electrical consuming devices with alternate fuel-driven mechanisms, e.g., by natural gas cooling. Use of state-of-the-art gas cooling technologies can reduce an installation's electric demand, provide domestic hot water, and lessen environmental impacts normally attributed to electric-driven chillers. This study evaluated absorption chillers, engine-driven chillers, and desiccant dehumidification systems as possible alternatives to electric cooling equipment at Air Force facilities. Site candidates were screened, economic costs/benefits analyses of applying gas cooling technologies at specific locations were done, and new equipment was purchased, installed, and tested at approved sites. Recommendations were made regarding the use of gas cooling technologies at Air Force facilities as a whole.
