September 24, 2012 energyair Share this post Energy Air, Inc. recently completed the HVAC scope of work for the expansion of UCF’s Partnership III data room. The scope included demolition and removal of the existing 10-ton Liebert system and the installation of (1) 46-ton Liebert XD chiller system consisting of (5) 9-ton CRAC (Computer Room Air Conditioning) units. New hot gas and liquid circuits for the new XD system were installed, and additional circuits were provided for future expansion. Existing controls modifications were also made so the new XD system can be monitored by UCF through the existing JCI building automation system. The Liebert XD system is a refrigerant-based, high-heat density system that delivers data center cooling for more than 30kW per rack. It utilizes pumped refrigerant, which is ideal for use around electronic equipment, and it enhances the hot aisle/cold aisle approach to cooling for floor-mount, rack-mount and ceiling-mount configurations. Since our team completed this scope within an occupied building, extensive planning and coordination had to take place to allow for a clean and smooth installation. Energy Air, Inc. installed the HVAC system in 2010 for the new Partnership III building located in Research Park on the main UCF campus. The LEED Gold building includes approximately 26,992 square feet of research labs and 85,000+ square feet of classrooms, offices and computer labs. Users of the building include organizations and groups involved with modeling, simulation and advanced distribution learning. The five-story building was built with 400 tons of cooling; 40 tons of which provide cooling for the data center. Energy Air was contracted by Clancy & Theys Construction Company for the new Partnership III building as well as the recent data room expansion.
