AirCalc_ vs Psychrometric Chart Usage & Stats

The state of moist air is shown by pressure, dry-bulb temperature, relative humidity, specific enthalpy, specific volume bulk, etc. These values can be calculated if each expression of relations shows three values. Usually, since pressure is used under normal atmospheric pressure in many cases, if this is set constant and two status values are given, it can calculate other values by calculation. By using this program, each status value read in the psychrometric diagram can usually be calculated easily. Use of the range of dry-bulb temperature DB-20℃ to 90℃ is assumed. Even if it exceeds this domain, calculation may be possible, but the error will be larger.

Psychrometric Chart

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. ------ We would very much like your feedback!
