Comparing HVAC System Air Flow Methods
|Flow Hood||Traverse||Temp Rise
|Recognized by Standard 310||Yes||Yes||Yes||Yes||No||No||No|
|Time (Min)||5 to 10||5 to 10||8 to 15||4 to 8||15 to 30||5 to 20||4 to 8|
- There are several methods for measuring HVAC system air flow.
- For residential HVAC systems, consider the four methods recognized by standard 310 (ANSI/ACCA/RESNET standard for grading new installs).
- When determining overall value, we consider 4 main criteria — Real-world Accuracy, Consistency, Cost and Time.
