Durham Research Center
This energy savings plant consist of modular water cooled chillers that produce chilled water for cooling and hot water for hydronic re-heat simultaneously. The hot water rejected from the water cooled chillers produces 140°F water. This higher temperature heating water is used in the reheat coils for VAV systems. The Dedicated Heat Recovery Chillers (DHRC) reside inside the building in a mechanical room and is of modular design for easy installation in existing facilities. This system will reduce the overall steam consumption of the both research towers by 4,000 lbs/hr and will be operated year round. This project is targeted to payback in less than two (2) years.
