| 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)

Features
|
- 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.
|
- Accurate calculators
With psychrometric calculators, you can get what you want accurately and
quickly. Furthermore, except for keyboard inputting, you can also pick data from anywhere in
the chart, especially endpoints of existing objects. By clicking a "Create..."
button in a calculator, you can convert your calculation result to an object
(point, line, coil, etc.) for later use.
|
- 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®.
