modelVarMoistAirExchange
Heat and moisture flow caused by air exchange
Extends from AixLib.ThermalZones.HighOrder.Components.DryAir.VarAirExchange (Heat flow caused by air exchange).
Information
Overview
The VarMoistAirExchange model describes heat and moisture
transfer by air exchange (e.g. due to opening a window). It needs the
air exchange rate (in 
) as input value.

Adding latent heat output of moisture, since ventilation moisture is already gaseous. - April, 2019, by Martin Kremer:
First Implementation.
