PsychroMoist

          PsychroMoist performs high-precision calculations of thermodynamic properties of humid air.  It implements the latest mathematical models for the simulation of the physics of water vapor, dry air and humid air as real gases.  Given a combination of two thermodynamic  properties of humid air and a value of pressure, it calculates 39 thermodynamic properties of humid air, dry air, water, water vapor and ice. The results obtained are suitable for scientific or industrial use, HVAC, meteorology and related fields. 
 
-Performs all the calculations implementing the latest mathematical models used to generate the tables for moist air properties and thermodynamic properties of water in the 2009 ASHRAE Handbook of Fundamentals.
