Allows you to do psychrometric calculations in MS Excel. ¡Get Psyched! 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)

Can also quickly and easily plot points on a psychrometric chart. The chart will correct automatically to any altitude that you select, up to 15,000 ft. or 5,000 meters.

Expertise Required: 

Any user familiar with Excel won't have any trouble using it.

Audience: 

Engineers, researchers and others interested in psychrometric properties of moist air.

Input: 

User supplies two known quantities such as dry bulb temperature and wet bulb temperature. From these the functions allow you to find other unknown properties such as dewpoint temperature, relative humidity, enthalpy, etc.

Output: 

The package includes a psychrometric chart in Excel where points or processes can be plotted. Results can also be added to any Excel spreadsheet such as the user's own analysis template.

Strengths: 

Psychrometric analysis for HVAC processes in a spreadsheet.
