Our Get Psyched software will allow you to do psychrometric calculations in MS Excel. The software is based on ASHRAE correlations and is more than accurate enough for HVAC applications. It works with both English (IP) and Metric (SI) units.
With our Get Psyched Excel add-in, you can calculate the following properties in any Excel spreadsheet for psychrometric calculations. It is compatible with MS Excel 2003/2007/2010.
The chart will correct automatically to any altitude that you select, up to 30,000 ft. or 10,000 meters. The functions are accurate between -60°F and 120°F or between -50°C and 50°C. The software can calculate Grains as well (IP functions only).
Metric functions are now supported with the same easy function calls from Excel. Also, the software comes with a metric psychrometric chart where you can plot points or processes.
Help and psychrometric chart templates are now available from a PDF.
