This post is the first in a series of 4 (maybe more) PowerPoint presentations that I am doing for my Company engineers about Pschrometry.
Without the benefit of narration it loses some of its usefulness. But I still think it can be very useful for anyone in the HVAC field trying to learn the subject for the first time.
Note that on the top left corner there is a little notes button that has some more comments on the slide.
