Summary & Background The Fulton County Justice Center (JCC) is cooled by three (3) 900-ton chillers in the Central Energy Plant (CEP). The HVAC equipment in the CEP was installed in 1992. The life-expectancy as outlined by the American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE) states that the average life-expectancy of this type of equipment is 23 years.
Chiller No. 3 will be replaced with a new chiller of equal size. Rather than install a 4160v machine like the existing chiller, a step-down transformer will be installed to allow for the installation of a 480v chiller that is easier to maintain. The primary chilled water pump that serves Chiller No. 3 will also be replaced as part of the project.
Scope of Work: This cooperative contract will furnish all materials, labor, tools, equipment, and appurtenances necessary to provide upgrade/ replacement of the existing HVAC mechanical equipment Chiller No. 3 to a more-high energy efficient, reliability, cost- effective and fully operational system at the Fulton County Justice Center Complex located at 185 Central Avenue, Atlanta, GA 30303.
