modelMixingVolumeMoistureReverseFlow
Validation model for mixing volume with moisture input and flow reversal
Extends from Buildings.Fluid.MixingVolumes.Validation.BaseClasses.MixingVolumeReverseFlow (Test model for mixing volume with flow reversal).
Information
This model validates the use of the mixing volume with air flowing into and out of the volume and moisture added to the volume.
The model volDyn uses a dynamic balance,
whereas the model volSte uses a steady-state balance.
The mass flow rate starts positive and reverses its direction at t=5 seconds.
