Precis was hired by Penn State to provide engineering design for the removal and replacement of two water-cooled chillers, cooling towers, associated pumps, and medium voltage switchgear at the end of life from Bryce Jordan Center, the university’s 15,000-seat multi-purpose arena.
The items were replaced with two new 700-ton, 316 stainless steel plate and frame heat exchangers. These were connected to the campus chilled water loop with flow meters and redundant campus and building pumps. The project included upgrade of all existing air-handling unit chilled water coil control valves with Belimo energy valves for improvement of system delta-T, as well as outside air flow monitoring for the arena air-handling units, and associated sequence-of-operations upgrades to allow for demand-controlled ventilation within the arena.
