CERL HVAC Test Facility

Vicksburg, MS

The air distribution system has a primary air intake with a mixed air section consisting of mechanically linked outdoor and return air dampers and a separately actuated exhaust damper. The supply fan feeds a single or dual-duct air system (as dictated by the particular system configuration being used). The return air duct is arranged so the return fan can be used or by-passed. Both the supply and return fans are modulated by variable speed drive units. A separate ventilation system contains an outdoor environment simulator (OES) consisting of heating and cooling coils, which permit conditioning of outdoor air to establish desired test conditions. Airflow measurement stations are installed in each primary and branch duct.
