ACMV Airflow Measurement Calculator Guide
A Professional Tool for HVAC Airflow Measurement and Documentation
How to Use the ACMV Airflow Measurement Calculator
STEP 1: Enter System Information
- » Enter the system type (e.g., ACMV)
- » Specify the equipment name (e.g., AHU-05)
- » Input the location (e.g., Level 3)
- » Add the drawing number for reference
STEP 2: Configure Measurement Instrument
- » Input the model name of your measurement instrument
- » Enter the serial number
- » Select the last calibration date
STEP 3: Perform Airflow Measurements
- » Enter the total system CMH and number of grilles
- » Click "Calculate Design Flow" to get the design airflow per grille
- » Add grilles using the "Add Grille" button
- » Input grille dimensions, free area, and velocity measurements
- » Click "Calculate All" to compute airflow for all grilles
- » Download a PDF report with "Download PDF Report"
How the ACMV Airflow Measurement Calculator Works
STEP 1: System Parameters Calculation
- » Divides the total system CMH by the number of grilles to calculate the design airflow per grille
STEP 2: Grille Airflow Computation
- » Uses grille dimensions (width x depth), free area, and velocity measurements to compute actual airflow
- » Formula: Airflow (CMH) = (Width/1000) × (Depth/1000) × Average Velocity × Free Area × 3600
STEP 3: Report Generation
- » Compiles system information, instrument details, and grille measurements into a professional PDF report
- » Includes a table comparing actual airflow with design airflow
