However, after inspection the plant learned it would take over a month to complete its repairs. The main cooling equipment including chillers, pumps, chemical treatment, controls and heat rejection equipment is housed in the central plant. R&D is progressing with next generation refrigerants. Speed Required Power 100% 100% 90% 73% 2. 240 ton centrifugal chiller costs $107,000 to $130,000. Central Chiller Plant – Chilled water is typically generated at the central chiller plant by compressor driven chillers, absorption chillers or other sources like ambient cooling or “free cooling” from deep lakes, rivers, aquifers or oceans. To determine the best chiller to use in a specific application, factor in efficiency, equipment and installation cost, maintenance cost and recurring costs. Preface This Operations and Maintenance (O&M) Best Practices Guide was developed under the direction of the U.S. Department of Energy’s Federal Energy Management Program (FEMP). • AHU coils designed for 39 °F supply • System of 20ΔT -23°F • PIC or Flow Limiters at each AHU-V • Average load 3,100 tons • Peak load 13,000 tons Chiller is equipment commonly used in HVAC or industrial applications to cool liquids to low temperatures.
