Tinora New Middle School

Defiance, Ohio

Mechanical

The mechanical system includes multiple indoor air handling units. The units contain a combination of supply and exhaust fans with variable speed drives and chilled water and hot water coils to maintain the unit’s discharge air temperature. Individual zone control is accomplished with fan powered variable air volume reheat boxes. The heating water plant utilizes high efficiency condensing boilers with hot water temperature reset and variable speed distribution. The chilled water system also utilizes variable speed pumps to distribute the water to the air handling units from the air cooled chillers. To offer optimal energy savings, the classroom air handling units and locker room units also include an energy recovery wheel to precondition the outside air. In addition, the gymnasium units incorporate demand controlled ventilation to reduce the outside air when it is not fully occupied. The entire mechanical control system utilizes an automated web-based control system.
