CYTSoft Psychrometric Chart 2.2 is an interactive and intelligent psychrometric chart program designed for thermodynamics-related industries, especially HVAC and refrigerating. It helps engineers calculate, analyze, draw, edit, print, and export conditions and processes of moist air quickly and accurately.

Traditionally, moist air is modeled as a mixture of two ideal gases by most psychrometric charts and calculators. By contrast, CYTSoft Psychrometric Chart treats dry air, water vapor and moist air as REAL GASES to get much higher accuracy and larger extents. Thus, this product is especially useful where high precision is required.

Psychrometric Algorithms

This product provides the most accurate and reliable data based on dozens of formulations developed by R. W. Hyland and A. Wexler, in whose reports published by ASHRAE, dry air, water vapor and moist air are all treated as real gases, rather than ideal gases.

Ranges in SI units:
  • Barometric pressure: any value between 20,000 and 500,000 Pa, or between 150 and 3,750 mmHg
  • Dry-bulb temperature: -50 to 200 deg C
  • Humidity ratio: 0 to 120 g(water)/kg(dry air)
Ranges in I-P units:
  • Barometric pressure: any value between 2.9 and 72.5 psi, or between 5.906 and 147.65 inHg
  • Dry-bulb temperature: -58 to 392 deg F
  • Humidity ratio: 0 to 0.120 lb(water)/lb(dry air)
  • Completely customizable chart

    You can customize almost everything of the chart to suit your preferences. The altitude, pressure, dry-bulb temperature range and humidity ratio range can be specified by the user. Lines and curves for different parameters are shown in different colors, widths, densities and visibilities which can be changed by the user whenever necessary.

  • Viewing chart details conveniently

    The PAN/ZOOM commands, windows scroll bars, mouse wheel, and shortcut keys (arrows, +/-, Page Up/Down, and Home/End) make you enjoy viewing every detail of the chart with ease.

  • Various kinds of objects drawn on the chart

    You can draw points, straight lines, cooling coils, mixing lines to represent different air conditions or processes. And any position of the chart can be marked by a label or a note. All objects are editable! That is, You can change their properties (including parameters and appearances) at any time after they are created.

  • Unlimited history

    Every action you perform when creating or modifying objects on the chart is recorded and may be undone and redone.

  • Powerful print

    You can print a picture of the chart, and you can print a tabular report for objects on this chart. Alternatively, you can export or copy them into anther application and then print in that app.

  • Working with other programs

    You can insert a chart or report in other programs. For example, you can export the chart (including all objects drawn on it) as a Microsoft® Windows®-format metafile and then insert it into your AutoCAD® drawings to edit. You can copy the chart or report to clipboard and paste it into Microsoft Office®.
