Zone Multiplier and Airflow Rates

edit

The 'FanCoil_HybridVent_VentSch.idf' example file is a good one to use to test whether ZoneVentilation:DesignFlowRate and ZoneMixing are affected by zone multipliers, since it is set up with both those objects (and output variables). Let's science this:

Hypothesis: ZoneVentilation:DesignFlowRate and ZoneMixing object inputs are unaffected by zone multipliers.

Method:

• Run unmodified example file
• Change the multiplier for 'North Zone' in the example file, run modified file.
• Verify that the zone design loads were affected as expected.
• Check if the output variables 'NORTH ZONE:Zone Ventilation Standard Density Volume Flow Rate' and 'NORTH ZONE:Zone Mixing Total Heat Gain Energy' remained unchanged.

Conclusion: Hypothesis verified. ZoneVentilation:DesignFlowRate and ZoneMixing object inputs are unaffected by zone multipliers, and should be adjusted accordingly.
