Supply chain supply air VAV air volume flow saturation evaluation (SplyVavSuSrt11)
Overview
(for future use)
The application function "Supply chain supply air VAV air volume flow saturation evaluation 11" (SplyVavSuSrt11) evaluates the supply VAV saturation signal(s) from the room segments for use in fan speed optimization.
Function
(for future use)
Depending on the number of supply saturation signals (NumVavSuStrtn) the fan speed can be adjusted.
The signal for damper saturation is a binary value object. It is True when the air flow control loop cannot get enough air to reach setpoint.
The value is True when:
- Damper position exceeds a configured damper saturation level, AND
- Air flow error exceeds a configured air flow error level, AND
- Both conditions stay true for more than a configured delay interval.
Configuration
None

Engineering and commissioning
By implementation of a project specific solution this function could be used. The value of NumVavSuStrtn can be picked up by the primary AHU by BA-addressing and the fan speed could be set with a function.
