Interactive, graphical psychrometric chart app for HVAC engineers and designers.
Processes that can be modeled include:
• An individual state point.
• Air mixing.
• Sensible heating.
• Sensible cooling.
• Cooling coils.
• Other processes by connecting state points.
Add new state points by double clicking anywhere on the chart. Click and drag existing state points to move them on the graph, with properties values updating live to aid you in setting them to the right value.
Works in both SI and IP units.
Allows the creation of multiple charts.
Properties and energy change for connected points are calculated and displayed live.
Share your charts by exporting a PDF file or sending to a supported printer.
We would very much like your feedback!

Ratings and ReviewsSee All
I like this app and am enjoying it’s functionality. A few things I would like to see are the ability to change the positions of labels, so they don’t overlap, and the ability to save and re-open specific charts I’ve made.
Developer Response ,
Glad the app is working well for you. The labels can be moved. To move, select a label by tapping (will turn red). Then hold and drag the label to the desired location. Also, you can save and restore multiple charts on the device. The list of saved charts can be displayed by swiping from the left edge of the screen to the right, or by selecting "Charts" in the upper left corner.
Doesn’t show grains of moisture
Developer Response ,
The app can indeed show grains per pound of dry air for humidity ratio. Go into settings and change the units for Humidity Ratio to grains/lb, rather than the default lb/lb. Grains of moisture per pound of dry air will now display.
Hope this helps. Feel free to contact us at https://www.pheinex.com/contact/ if you have any additional questions.
Really cool but why not have tonnage in latent and sensible loads
With Family Sharing set up, up to six family members can use this app.
