modelVarAirExchange
Heat flow caused by air exchange
Extends from Modelica.Thermal.HeatTransfer.Interfaces.Element1D (Partial heat transfer element with two HeatPort connectors that does not store energy).
Information
Overview
The VarAirExchange model describes heat transfer by air
exchange (e.g. due to opening a window). It needs the air exchange
rate (in 
) as input value.
