Powered flow hoods have proven to also be successful in the measurement of supply airflows in which the nonuniformity of air entering the flow hood due to supply grille geometry is counteracted by the use of the fan coupled with high-airflow-resistance flow straighteners and measurement methods (Walker and Wray 2003; Wray et al.
They found that the placement of the capture hood over the grille and the directional flow out of supply grilles had a large effect on the measurements.
Air passes from the metal deck (13) to the low level plenum (3) and discharges through the air supply grille (10).
Air velocity decreased while going further from the air supply grille and became equal to the air velocity of the premises at points 5V and 6V.
The instruction card gives clear directions on how to hook up the components to measure duct air velocity, supply grille velocity, return grille velocity static pressure, and, if needed, furnace draft and air filter test.
Keeping the air velocity high and the airflow straight as it leaves the supply grille is important for good air mixing.
Locate supply grilles or registers directly above the patient bed; consider locating exhaust grilles near the head of the bed.
