Frederick Community College Facilities Master Plan Chapter 5 The College Today 5-C-1 May, 2023 CENTRAL PLANT The Frederick Community College (FCC) central chilled water and heating water plant is located within the campus Athletic Center (Building D). The chilled water and heating water plant was originally built in 1994 and has undergone multiple renovations. Namely, major renovations to the central plant occurred in 2008, 2011, 2016, and 2017. Underground chilled water and heating water piping delivers chilled water and heating water to the existing campus buildings. Table 1 below summarizes the estimated connected cooling load and heating load seen by the central plant. It should be noted that some buildings are not currently supported by the central plant and have dedicated HVAC systems.

Estimated cooling and heating demand is based off of approximate SF/Ton and SF/MBH. Central Chilled Water System Existing Conditions The existing central chilled water plant is comprised of three (3) water cooled centrifugal chillers, two (2) induced draft counter flow cooling towers, six (6) chilled water pumps and six (6) condenser water pumps. The plant operates as a primary / secondary constant volume chilled water plant. The primary chilled water pumps distribute water to each building where secondary distribution pumps circulate water through the various campus buildings. Due to the current chilled water and condenser water piping configuration only two (2) chillers can operate at a time which limits the central
