Psychrometric Chart is an interactive and graphical app designed specifically for HVAC engineers and designers. With this app, users can easily create and manipulate charts and state points using simple touch gestures.

This powerful tool allows for modeling various processes including individual state points, air mixing, sensible heating, sensible cooling, cooling coils, and other processes by connecting state points. Adding new state points is as easy as double tapping anywhere on the chart, and existing points can be moved by holding and dragging them.

The app supports both SI and IP units, making it flexible for different users. Multiple charts can be created and saved, allowing for easy organization and access to different projects.

One of the standout features of Psychrometric Chart is the live calculation and display of properties and energy changes for connected points. This real-time feedback helps to ensure accurate and efficient design.

Additionally, users can easily share their charts by exporting them as PDF files or sending them to an AirPrint device. The app is compatible with both iPhone and iPad, although it is best utilized on the larger screen of the iPad.

Please note that this app is intended for use by qualified HVAC engineers and designers and should not be used as a substitute for appropriate design services. For any doubts or concerns, it is recommended to contact a design professional.

Overall, Psychrometric Chart offers a comprehensive and user-friendly solution for HVAC engineers and designers, providing them with the tools they need to efficiently design air handling systems.
