Inflow Velocity – DIM Method (Primary)
Description: Inflow velocity using the direct inflow measurement
method (DIM).
Equipment: . . .Shortridge ADM-870, or equivalent
. . . . . . . . .Flow hood Series 8400, or equivalent
Method:
1. Move the front window to the work position (25.4 cm/10 in).
2. Attach the flow hood [1] in the work opening [2] and seal the
remaining open areas.
3. Operate the system blowers for approx 20 min.
4. Record at least 5 measurements of the inflow air volume.
5. Average those readings and calculate the inflow velocity (V1) as
described below.
Application
Airflow pattern test
Downflow velocity test and alternate method for inflow
velocity using constricted access
Electrical leakage and ground resistance tests
