modelAirRenewal_DynProp
Extends from BuildSysPro.BaseClasses.HeatTransfer.Interfaces.Element1D (Partial heat transfer element with two HeatPort connectors that does not store energy).
Information
Simple air renewal model for a single zone with variable air properties
Hypothesis and equations
Based on AirRenewal model.
Added a table of air properties, so that the calculation takes into account the variations of air thermo-physical properties depending on the temperature.
