Performance Evaluation A performance evaluation of the system can be performed only after all of the following items have been verified: 1. All fans are operational and rotations visually verified by observation of the arrows stamped on them. 2. All filters are in place. 3. Equipment under the hood is in place and operational. 4. HVAC units are in place and operational with blowers operating correctly.
Using a Shortridge Instrument The Shortridge is a sophisticated instrument that, with its built-in features, is basically a self contained test and balance kit.
If both the length and width are measured in inches, use the following formula: Area (ft²) = Length (in) x Width (in) / 144 2. Record velocity of air through supply openings from left to right on raw data sheet. 3. Compute and record average velocity through supply openings. 4. Compute and record CFM through supply openings. CFM = Free area x Average Velocity 5. Compute total CFM through all supply openings for each hood. Calculating Exhaust Air CFM with a Shortridge Instrument and Spreadsheet 1.
Adjustments 1. A hood with multiple risers should be balanced according to the cooking load beneath it. For example, if a hood with multiple risers has a charbroiler in the center and several ovens on the ends, the risers should be evenly balanced. This will achieve the most efficient contaminant capture. 2. Perforated supply plenums discharging air around the hood should be set to the designed discharge velocity. 3.
Troubleshooting The following table lists causes and corrective actions for possible problems with exhaust hoods. Review this list prior to consulting manufacturer.
