blockTDewPoi_pW
Model to compute the dew point temperature for given water vapor pressure of moist air
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
Dew point temperature calculation for moist air above freezing temperature.
The correlation used in this model is valid for dew point temperatures between 0°C and 200°C. It is the correlation from 2005 ASHRAE Handbook, p. 6.2. In an earlier version of this model, the equation from Peppers has been used, but this equation yielded about 15 Kelvin lower dew point temperatures.

Changed from causal to acausal ports, needed, for example, for Buildings.Fluid.Examples.MixingVolumeMoistAir. -
