Studies: Cogeneration - Chicago Museum of Science and Industry
Location: Chicago, IL
of Science and Industry installed a 1.75-megawatt cogeneration system aimed at
providing heat, power, and dehumidification to the museum. The system, comprised
of a Cummins Inc. QSV91GB lean-burn reciprocating engine-generator set and a Munters
AM30N-S Drycool desiccant dehumidification unit, can pull moisture from 10,000
cubic feet of air per minute. It will operate approximately 3,380 hours per year.
generator-set system will provide electric power as well as high-pressure steam
(produced from the engine jacket water and engine exhaust), which will be fed
into the museum's existing steam header. The electrical generator will be connected
in parallel with the Commonwealth Edison Company's electrical grid and will operate
as a peak-shaving system. The Munters unit will condition building air by removing
moisture during summer months using a desiccant wheel and by preheating incoming
air during winter months. The Munters unit uses steam produced by the heat from
the Cummins generator-set.
since 1933, the museum is the oldest of its kind in the Western Hemisphere and
is one of Chicago's largest tourist attractions. It is among the seven most visited
in the United States; nearly 400,000 children (school groups and youth organizations)
visited in 2000.
