PsychromeTree is a MUST HAVE for HVAC Engineers and Technicians or anyone else that needs to calculate properties of moist air (in other words, deal with Psychrometry or Psychrometric Analysis).

This app can be used to calculate:

- Air Mixes

- Free Cooling Capacity

- Required Humidifier Capacity

and much more.

You enter only two parameters, the Dry Bulb Temperature and one of the following:

- Wet Bulb Temperature

- Relative Humidity

or Dew Point Temperature

PsychromeTree will calculate:

- Wet-Bulb Temperature

- Relative Humidity

- Dew Point Temperature

- Humidity Ratio

- Specific Volume

- Enthalpy

You can configure PsychromeTree to work in Metric or Imperial standards and to compensate for a specific altitude making the calculations even more precise.

For a detailed description and instructions on how to use PsychromeTree please visit our website.

What a life saver

Seriously I have been looking for this for a while, guys and gals I'm not in hvac but I'm in the water damage restoration, where we use dehumidifiers, I only need this to find GPP and that only simply by having temp and RH typed in ... So 5 stars from me
