blockRelToAbsHum
Converts relative humidity to absolute humidity
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
Simple model that converts absolute humidity to relative humidity taking into account the air temperature. It is based on Magnus formula and the ideal gas law. All coefficients are based on typical assumptions and combined to one coefficient for reduction of computational effort.
The model has been validated against exemplary values calculated with http://www.ib-rauch.de/bautens/formel/abs_luftfeucht.html and deviate around maximum 2 Percent.
