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.
I finally added some testing and balancing features. Right now it's just a fan law calculator and I'll add a pump law calculator shortly.
I also allowed changing the humidity ratio to be represented in grains.
