PsychroMoist performs high-precision calculations of Thermodynamic and Transport properties of humid air.
Given a combination of two thermodynamic properties of moist air and a value of pressure, it calculates 39 thermodynamic properties of moist air, dry air, water, water vapor and ice. It incorporates the latest mathematical models for the simulation of the physics of water vapor, dry air and moist air as real gases.
The numerical results obtained are suitable for scientific, industrial, HVAC, meteorology, engineering and related fields.
Psychrometric variables in the SI (metric) system of units can be entered and/or the calculation results can be displayed in the following units (w = water, da = dry air):
