Goal: Calculate the common properties of moist air using the psychrometric chart. Another goal is to use these calculated properties to help identify potential indoor air quality problems.

Lesson 1: Chart Basics

Objective – Describe the x and y axes of the psychrometric chart, understand movement around the chart, and explain the concepts of sensible heat, latent heat, and enthalpy.

Lesson 2: Getting Oriented

Objective – Identify the 7 different lines on the psychrometric chart.

Lesson 3: Calculations

Objective – Plot the given conditions on the psychrometric chart, calculate other properties, and graphically display air mixing and process changes.
