.Buildings.Controls.OBC.CDL.Psychrometrics.SpecificEnthalpy_TDryBulPhi

Information

This block computes the specific enthalpy for a given dry bulb temperature, relative air humidity and atmospheric pressure. The specific enthalpy is zero if the temperature is 0°C and if there is no moisture.

The correlation used in this model is from the 2009 ASHRAE Handbook Fundamentals, p. 1.9, equation 32.
