modelAirVP

Greenhouse air vapour pressure by numerical integration of the differential equation of the moisture content

Information

This model applies the mass balance on the moisture content of the air. The water vapour pressure of the air is computed by numerical integration of the differential equation of the moisture content. The mass balance takes into account all the flows connected to the vapor port.
