HVAC Distribution System

HVAC systems included 36 individual rooftop air handling units (AHU) located throughout the facility. Most of the HVAC units serving the test cell and preparation areas conditioned 100% outside air and included a steam preheat coil, chilled water cooling coil, steam reheat coil, steam humidifier, and supply fan. To reach their summer temperature and humidity set points, the units would overcool and over-dehumidify, then reheat and rehumidify their single-pass air. Other preparation and office areas had one AHU with a deficient VAV system and 11 AHUs that were constant volume reheat systems, with steam humidifiers and reheat coils located in the distribution ductwork.
