modelConvection_Evaporation
Upward heat exchange by free convection between the thermal screen (filled port) and top air (empty port). Mass transfer by evaporation from upper side of the screen to the air at the top compartment
Extends from Greenhouses.Interfaces.HeatAndVapour.Element1D (Partial water mass transfer element with two WaterMassPort connectors that does not store energy).
