Detroit airport expansion includes mechanical plant.(News)
DETROIT. MI--"This is a challenging facility in which to maintain comfort levels. with lots of solar gain and greatly fluctuating occupancy rates," says Metro Energy operations manager Dave Kiselewski. referring to the energy center serving the new Detroit air terminal: the Edward H. McNamara Terminal at the Northwest WorldGateway.
Metro Energy is the energy service partnership that was responsible for construction of the mechanical plant serving the new terminal. and has a 30 year con tract fur plant operation and maintenance. The partners in Metro Energy consist of Detroit-based DTE Energy Services and Pittsburgh-based DQE Energy Services.
Many of the systems that sup port the terminal are located ill a remote mechanical plant. Design engineering for the mechanical plant was done by Cummins & Barnard of Ann Arbor, MI. The plant houses a cogeneration system, hot water boilers, and the chilled water plant. The cogeneration system features three 5.7-MW Wartsila diesel engines that use natural gas fuel. These 18 cylinder machines, totaling 17.0 MW. can supply all essential electric services in the terminal. Hot water for space heating is provided by three boilers operating at a maximum 350[degrees]F (177[degrees]C) and 250 psi (1720 k Pa). Three heat recovery boilers provide additional hot water to the system when the cogeneration system is in operation.
The heart of the chilled water plant at the energy center is a row of seven Trane CenTraVaC two-stage hermetic centrifugal chillers. The chillers are installed on a chilled water loop with a Systecon variable speed pumping package. Ally combination of pumps can be used with any chiller. This approach adds to the reliability and efficiency of the system. The ...
