Fort Gordon energy survey analysis of boiler and chiller plants, building 25910 and building 25330. Proposed energy conservation opportunities for Savannah District Corps of Engineers. Volume 1 of 3. Final report
Project No. 1 is all of the recommended ECO`s combined for the chilled water system in the North area, which is controlled and supplied from Building 25910. The attached project drawing shows an upgrade and general layout of equipment, showing the reuse of the existing cooling towers with new piping from them which will go through a free cooling heat exchanger. There will be pumps at each chiller that will extract the required amount of cooling water through a loop piping arrangement. Chillers 5, 6, and 7 are existing, but new higher efficiency chillers will be added in the size range of one 400 ton and two of 1,250 ton chillers. Return chilled water will either be run in a loop that will feed any of the chillers which have its new pump `on` to circulate the chilled water through it, or if no pumps are `on`, the water will circulate through the new free cooling plate heat exchanger to be located in Building 25910. Teed off of the return chilled water system there will be a pipe that feeds a chilled water storage tank which will be located behind the Plant in the woods. There will be a pump parallel with that line so that if additional pressure is needed to get the water up to the top of the storage tank, that pump will come on. The water in that pipe and water in the pipe leaving at the bottom of the chilled water storage will go back to the Plant. Both of these pipes will have flow in either direction, depending on whether the storage tank is being charged as it will be at night in the summer time, or whether it is being discharged during the peak cooling hours during the day in the summer. The existing chilled water distribution pumps will remain in operation, but the drives will now be controlled by a single variable speed drive.
