Steps
- Build a scaled duct system feeding 2 or 3 zones from the blower fan.
- Add a servo-driven damper and temperature sensor in each zone.
- Measure airflow at each zone outlet with the anemometer.
- Test how different damper positions change airflow and zone temperatures.
- Find the damper settings that balance the zones.
- Chart the results and document the system for your portfolio.
What to photograph for your portfolio
- Ducted demo build
- zone temperature logs
- damper vs airflow tests
- balancing analysis
