All Five Air Handler Average Runtime Speeds

Mouse over graph to see actual values. Mouse over equipment names (on right) to highlight graph.

All fan speeds are capped at 75%. Fan CFM is directly proportional to fan speed. All fans are only operating, effectively, at 75% of design air supply. This works for the heating season but may not for the cooling season.

Comments:

• AHU-01 doesn't run much. Speeds are close to zero except on some daily startups
• AHU-02 SF speed ~57%. Matching RF ~36%
• AHU-03 SF speed ~70%. Matching RF ~60%
• AHU-04 SF speed ~72%. Matching RF ~64%
• AHU-05 SF speed ~68%. Matching RF ~1% - not really running
