ASHRAE Psychrometric Chart App

Now Available for Apple/iOS devices psychrometricapp_175px.jpg

The new ASHRAE Psychrometric Chart app is the first truly interactive graphical psychrometric chart for your iOS device, and it includes both I-P and SI units.

Easily plot HVAC and other psychrometric processes while out in the field, save the graphs, and then email the graph and results to yourself or clients.

<-- Watch this video to see the app in action

The ASHRAE Psych Chart app includes the following features and functionality:

  • Display a fully customizable psychrometric chart in both landscape and portrait modes.
  • Customize the graph in many different ways, including specifying the psychrometric chart line colors, chart background color, hide/display status of chart lines, point colors, process line colors, units of graph values, and the min/max limits of the chart.
  • Using your finger, plot as many points as you want on the screen. As you move your finger around the graph, the psychrometric properties at the top of the screen dynamically update. In addition, you can double-tap a point to display the point properties and then edit them.
  • Create psychrometric processes by plotting points then connecting them with process lines. Also, create custom labels anywhere on the chart.
  • Email a list of all the points and their properties for a completed chart, along with a PDF of the chart itself.
  • Create an unlimited number of psychrometric chart projects. Also, you can create templates that you can reuse over and over again.
  • Zoom in or out of the chart by "pinching" the iPad screen to view items in detail.

To download, iPhone/iPad users should visit the App Store and search for "ASHRAE App". Android app no longer available.

Psychrometric Analysis CD, Version 7

This CD includes all five of ASHRAE's I-P unit psychrometric charts and all seven SI psychrometric charts. The program on the CD allows the user to plot typical psychrometric processes and perform the corresponding energy calculations on-screen, without having to first print out the individual charts.

The program can output a listing of points and processes in a tabular report with calculated properties and energy values for each. It also includes a presentation of the ASHRAE climatic data from the 2009 ASHRAE Handbook—Fundamentals.
