Description
Psychrometric calculator for HVAC engineers, designers, technicians, commissioning agents, and maintenance personnel. SI and IP units are supported.Inputs:
- Altitude
- Dry Bulb Temperature
And either:
-Wet Bulb Temperature
-Relative Humidity
- Dew Point Temperature
To Calculate:
-Wet Bulb Temperature
-Relative Humidity
-Dew Point Temperature
-Atmospheric Pressure
-Barometric Pressure
-Enthalpy
-Humidity Ratio
-Density
-Specific Volume
-Vapor Pressure
Calculations are made using The American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) Fundamentals 2009 ideal gas equations.
You must hit the clear button in between calculations. If more than three properties are filled in the application will default to using wet bulb as the humidity input.

Love it. Just started learning psychrometrics in school and this app comes in very handy. Half the students in class have it. Definitely going to be using this in the field.

Good stuff Very nice, simple. Would be nice if when you hit enter in the dry bulb spot it would move to wet bulb, then hit enter & it calcs.
