How To Read the Psychrometric Chart - A Beginners Guide

This podcast episode is a beginner's introduction to the psychrometric chart. Here is what you will learn. Section 1: Properties of Air.  We explain the difference between Dry Bulb, Wet Bulb, Relative Humidity, Humidity, and Dew Point. Section 2: Building the Psychrometric Chart. A psychrometric chart is a graphical representation of the psychrometric processes of air. See how the psychrometric properties make up the chart. Section 3: We look at psychrometric processes such as cooling, heating, humidification, dehumidification, cooling, and dehumidification. Section 4: Relative Humidity vs. Dew Point.

Designers often rely on software to calculate the critical values related to cooling, heating, humidifying, and dehumidifying, but do we know how those measurement values are determined? Even though psychrometric charts can be intimidating, we’ll demystify the information they contain. You’ll finish the session with a better understanding of psychrometric charts, the properties of air, and the fundamental processes that drive climate control in a modern building.
