You do not understand HVAC until you understand psychrometrics.

Lesson 1.1 - 1.3 provide a quick review on the fundamental properties necessary to understand the principles of psychrometrics. These properties include mass, force, weight, density, specific volume, pressure, enthalpy, sensible and latent heat, and the basic properties of moist air. Lesson 1 concludes with an introduction to the Psychrometric Chart and it’s lines of constant properties.

Lesson 2.1 - 2.3 covers air conditioning processes on a psychrometric chart, the air mixing process, and concludes with a number of sample problems using the psychrometric chart .
