# Psychrometrics and the Properties of Air - Part 3

## What You Will Learn

In the first two sessions on Psychrometrics and the properties of air we discussed the basics of how to use a psychrometric chart, how to plot state points and how to calculate various processes on the chart. Join us for part three as we take a more in-depth look at the actual process of humidity control and the practical applications. We’ll also discuss the difference between full load and part load conditions and how this affects the overall performance of the system. One of the single most important topics we will discuss is why systems fail to properly control humidity.
