modelMixedAirHeatMassBalance

Heat and mass balance of the air, assuming completely mixed air

Extends from Buildings.ThermalZones.Detailed.BaseClasses.PartialAirHeatMassBalance, Buildings.Fluid.Interfaces.LumpedVolumeDeclarations.

Information

This model computes the heat and mass balance of the air. The model assumes a completely mixed air volume.
