Psychrometric + Duct Calculator

  Psychrometric chart

Use IFC-67 equation for water property calculating.
English and Simplified Chinese language support, or translate to your language by yourself.
Metric Units.
1. Export to disk file as jpg, jpeg, bmp, wmf or emf format.
2. Copy chart to clipboard as wmf or bitmap format.
3. Add print function, aspect ratio can be adjust by moving chart boder.
4. Moist and bulb temperature axis range can be changed.
5. Ambient altitude range from 0 to 40km, absolute pressure 0~25bar.
6. Illustrate dry bulb temperature, humidity ratio(or absolute humidity, moist content), constant relative humidity, constant enthalpy, constant specific volume, and constant wet bulb temperature.
7. Mouse point catch and calculate, output point air information and physical properties.
8. Calculate once and twice recycle air flow, both summer and winter state, process line shown in chart, press UpDown button to see process changing.
9. Many kinds of processing point manipulation.
10. Point defined by dry bulb temperature and another quantity which can be changed, automatically transformed from original quantity.
11. Point is optional to pick by mouse clicking on chart.
12. Calculate process parameter and mix point, process lines are optional to be visual.
13. Point definition transformed from another, and give warning and error information.
14. Optional chart ploting setup. preset and user defined configeration select, change, add and delete.
15. More precise and large internal drawing for smooth line appearance and print effect.

Duct Calculator

1. Calculate air and liquid duct.
2. Calculate round and rectangle cross section duct.
3. Calculate duct flow resistance, environmental heat exchange, and adiabatic effect.
Note: Outer coefficient of heat transfer usually 3~10, >10 when winds.
