Psychrometrics Program

Get Psyched!TM 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. You can calculate these properties in any Excel spreadsheet:
- Enthalpy (h)
- Dewpoint Temperature (dp)
- Relative Humidity (%)
- Humidity Ratio (W)
- Specific Volume (v)
- Wet Bulb Temperature (wb)
