CJL Engineering provided the mechanical and electrical engineering design for the 5,100-ton upper campus chilled water plant for the University of Pittsburgh. The massive 7,000 sq. ft. plant is 30 feet high, and houses three 900-ton and two 1200-ton chillers.
A primary, secondary pumping system utilizes a water pump for each chiller, and three secondary pumps with variable speed drives. The total capacity of the pumping system is 8,160 gpm designed for a 15 degree F. delta T.
Underground 20” chilled water piping, along with 12” high-pressure steam, 6” pump discharge, and 2” high-pressure return, were installed in a common 10’ side trench. The steam system consisted of over 1,000 ft. of high-pressure and six steam vaults.
