Chiller Plant Commissioning
The Chiller Plant Commissioning project provided commissioning services in Ann Arbor during the construction of a 4,000-ton central chiller plant at University of Michigan's North Campus. The central plant consisted of three (3) 1,300-ton variable-speed electric centrifugal chillers, with associated cooling towers, pumps, filters, and other appurtenances. The distribution system consisted of over a mile of direct-buried underground pipe (up to 30" diameter), and carried chilled water to 11 campus buildings (about 1,000,000 sq. ft. total building area). Commissioning tasks including participating in system start-up and trouble-shooting for chilled water (above and below ground), condenser water, water treatment, free cooling, and digital control systems.)
