Psychrometric Calculator is designed for HVAC and
refrigerating engineers/ designers to calculate highly accurate thermodynamic properties of moist air. The formulations
used to calculate moist air properties are based on perfect gas relations published in 1989 ASHRAE Fundamentals Handbook.
The program also includes a Psychrometric Chart where you can see the thermodynamic properties of moist air changing with
the movement of mouse.
The Online version of Psychrometric Calculator is available at www.jmrinfosys.com/psychrometric/ where
anyone can get the psychrometric properties of moist air without installing it on their desktop computers.
Accuracy : Uses perfect gas relations published in 1989 ASHRAE Fundamentals Handbook. The
Psychometric Calculator can be compared with any standard Psychometric Calculator available.
Various input checks have been incorporated to get correct inputs.
East to Learn, Easy to Use : The software is easy to use. Enter values of any
two properties of moist air and press enter, you will get values for all other properties of moist air.
Psychrometric Chart : The software provides a Psychrometric Chart that can be
saved and printed any time. Again, One can see the values of moist air properties changing with the movement of mouse.
