Wyman Elementary
St. Louis, MO
Wyman Elementary is an existing 58,000-square foot elementary school in
St. Louis where the existing heat system was steam heat only. Mechanical
Solutions provided the client with a central heating and cooling plant comprised
of one (1) air cooled chiller, two (2) large air handlers with VAV hot water reheat
boxes to serve each class room and two (1) boilers used for heating.
The challenge for this project was getting the large air handlers and new boilers
into the lower level of the building. Walls had to be removed and ramps had to be
built to safely move the new equipment in place. The other challenge was how
to get the air from all of the floors and ducting returns back to the air handlers in
the lower level while still providing air side economize for energy savings. Each
room ws ducted to the attic where it was gathered into a large return duct. Two
(2) huge return shafts were provided to get the air back to the air handling room.
During economizer mode (free cooling) the excess outside air was relieved thru
two (2) large relief dampers located in the attic.
