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. 小焓计算器，以帮助援助的暖通空调设计人员在每天的计算。根据ASHRAE公式计算。我希望能扩大到一个更强大的工具箱，将包括更多的工程学科。我也有模量计算器，我觉得方便的时候，均匀地分割CFM到扩散。 如果您有任何问题，请与我联系，我会尽我所能予以纠正。这是我的第一个应用程序，我不认为这是一个BETA版本。我一直没能在许多设备上进行测试。但是，所有的功能应该工作。
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.
