Publisher's Description:

Psychrometric + Duct Calculator - A convenient, precise and powerful tool for HVAC&R engineers. This psychrometric chart use ASHRAE equations at normal temperature and pressure region and is perfectly consistent with all ASHRAE charts of No.1~7(SI Units) and No.1~5(IP Units).

Full functional trial, free upgrade.

Both Metric(SI) and English(IP) units support.

Save and load data function for each data input grid, all input data can be saved for loading next time program started.

Psychrometric chart

1. Use IAPWS-IF97 equation for water/vapor properties calculating, and treat moist air as real gas for high precision;

2. Dry bulb temperature and humidity ratio axis range can be changed easily, the chart generation is automatic and fast;

3. Draw protractor for enthalpy-humidity and sensible-total heat ratio;

4. Mouse point catch, snap and calculation, output point information and many air properties;

5. Normal and eastern(China) style support;

6. Chart grid snap, aided constant parameter lines across cursor point, middle button pan and mouse wheel zoom for convenient chart operating;

7. Many process point managements, include point pick up, data input grid, point definition select, point add, insert, reduce, delete, move up and down, open and save point list;

8. Convenient interface for process and mix point calculating;

9. Once and twice recycle calculating;

10. Point state convert calculating, and give warning and error message, output point information if point state is OK;

11. Chart plot/display setup and management support;

12. Chart can be easily printed, copied to clipboard as bmp and wmf format, and exported as bmp, jpg, wmf or emf format.

Duct Calculator

1. Calculate air/liquid and round/rectangle cross section duct;

2. Calculate duct flow resistance, environmental heat exchange, and adiabatic effect.

Note: Outer coefficient of heat transfer usually 3~10, >10 when winds.

List of Changes:

Version 4.0 from 2008-08-20

Show all changes

Version 3.0 from 2007-06-16

I tried to use the psychrometric diagram and frankly speaking I had quiet some problems with it.
1. As I realized it's based on a chinese software and not all characters are well exposed (SI units).
2. I couldn't find a way to adjust the height above sea level. I live in Mexico and we are 2250m above sea level. Most of the projects and HVACR application are at heights of 1500, 2200 and 2600m above sea levels, hence I consider it as a must to have to choice to switch between different heights.
3. I prefer a way to key in the values I want but the program doesn't reflect it as desired.
4. To adjust line colors are widths isn't very user friendly
5. My overall impression is that the software isn't very user friendly and I believe certain steps in the program need to be simplified and improved.

Best regards
Franklin Feller

i need to calculate this space for the following conditions:

volume of the space is:
V= 331 m3(room volum)
sommer:
DB=34 grad celcius
RH=45%
i need in the room
DB=18 grad celcius
RH=45-50%
winter
DB=-1 grde celcius
RH= 75%
I NEED IN THE ROOM AGAIN :
DB=18 grad celcius
RH=45-50%
RESPECT FROM ING .LORENC MALKA
i need to calculate the dehumifier
and

Temperature range.

Your calculator is pretty good and simple to use, but like I'm searching for RH% in a higher temperature range ( over 100в°c) your product donesn't help me enough.
If any upgrade created, please tell me.
Thank you.


Author's Response:
Thank you for your sincere review. Although I have checked it carefully, there are still some defficiencies, I haven't taken notice of some special areas.
I'll include this in future version.
Temporarily, you can lookup this area from the quantity sheet in "basic" tab.

Best regards,
