.AixLib.ThermalZones.ReducedOrder.Multizone.BaseClasses.AirFlowRateSum

Information

This model calculates the volume flow (e.g. for an Air Handling Unit) for supply of thermal zones dependent on:

• Which zone is supplied by the AHU
• A minimal volume flow (minAHU) in m3/(m2*h) per zone
• A maxmial volume flow (maxAHU = deltaAHU + minAHU) in m3/(m2*h) per zone
• A given profile or relative occupation per zone

A vector of AixLib.DataBase.ThermalZones.ZoneBaseRecord records is necessary to evaluate which zones are supplied by an AHU. As AHUs typically work with m3/s, the model calculates the output air flow rate in m3/s.

Typical use and important parameters

The governing equation is:

airFlow = [minAHU + deltaAHU * (profile OR relative Occupation)] * Azone * 3600^-1

All parameter come from the vector of AixLib.DataBase.ThermalZones.ZoneBaseRecord records. The model is typically used as input adapter for AHU model in AixLib.ThermalZones.ReducedOrder.Multizone.MultizoneEquipped.

  Moved to fit to new Annex60 structure.
• February 26, 2016, by Moritz Lauster:
  To get the correct share of volume flow for each zone, more outputs are generated.
• October 30, 2015, by Moritz Lauster:
  Moved and adapted to AixLib. Some renaming and adding units.
