Description

Interactive, graphical psychrometric chart app for HVAC engineers and designers. Allows you to create and manipulate charts and state points with the touch of your finger(s).

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 tapping anywhere on the chart. Hold 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 you to create and save 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 an AirPrint device.

Works on both the iPhone and iPad, but best used on the larger screen of the iPad.
