Psychrometrics

Pro

Full psychrometric analysis with a printable ASHRAE-style chart.

Overview

Compute complete moist-air states from any two properties — dry-bulb plus wet-bulb, dew point, relative humidity, humidity ratio, or enthalpy — at any altitude, in IP or SI units. Plot named state points on a detailed psychrometric chart with RH, wet-bulb, enthalpy, specific-volume and dew-point line families, then print it to 11×17-style letter output for submittals.

Key features

• Five input modes: DB+WB, DB+DP, DB+RH, DB+HR, DB+h
• IP and SI units with altitude-corrected pressure
• Full property output: wet bulb, dew point, RH, humidity ratio, enthalpy, specific volume, density
• Detailed ASHRAE-style chart with toggleable line families and SHR protractor
• Named plotted points with traces; print / save to PDF

2. 2

   Set altitude and choose an input mode.

3. 3

   Enter your two properties and Calculate.

4. 4

   Plot Point to name and pin the state, then View Chart for the full chart.

5. 5

   Print / PDF from the chart page for documentation.
