Tanner, G R

The University of Redlands, located in the California Inland Empire City of Redlands supplies six campus building with chilled and hot water for cooling and space heating from a centrally located Mechanical Center. The University was interested in lowering chilled water production costs and eliminating Ozone depleting chloroflourocarbon (CFC) refrigerants in addition to adding chiller capacity for future building to be added to the central plant piping {open_quotes}loop{close_quotes}. After initially providing a feasibility study of chiller addition alternatives and annual hourly load models, GRT & Associates, Inc. (GRT) provided design engineering for the installation of a 500 Ton direct gas fired absorption chiller addition to the University of Redland`s mechanical center. Based on the feasibility study and energy consumption tests done after the new absorption chiller was added, the university estimates annual energy cost saving versus the existing electric chiller is approximately $65,000 per year. Using actual construction costs, the simple before tax payback period for the project is six years.
