Psycrometrics is the study of thermal and physical properties of air-water mixtures (moist air). The values of moist air properties are important to engineers in many disciplines. The Psycro module developed by HBC allows for the calculation of moist air thermodynamic properties within Excel.

By following the Download Psycro link, one will be able to save a zipped copy of the psycro xla file (Excel Add-in) along with a copy of the manual for the use of the file.

Since blind trust in files containing macros written in VB/VBA is not such a great idea these days, the source code to the psycro add-in file is available for download by following the Download Source Code link. With the source code, one is not limited to using the psycro functions in Excel--One could easily copy the code for use in an Access database or generate a DLL in Visual Basic.

Here are some screenshots.
