Small Psychrometric calculator to help aid in every day calculations for the HVAC designer. Calculations are based on ASHRAE formulas. I am hoping to expand this into a much more robust toolbox that will encompass more engineering disciplines. I also have a modulus calculator that i find handy when evenly splitting CFM to diffusers.

If you have any issues please contact me and i will do my best to correct them. This is my first app, and i do consider it to be a BETA release. I have not been able to test on many devices. However all functions should work.
