BACK TO BASICS: PSYCHROMETRICS AND THE PSYCHROMETRIC CHART
An understanding of psychrometrics and use of the psychrometric chart is essential to the process of designing thermal systems and sizing the coils that are part of these systems. Whatever the type of coil, the air stream going through it can be plotted on the psychrometric chart, and important information learned about the air stream. With this knowledge, a designer can answer questions and make decisions during the coil selection process. This article will cover some of the basic principles and concepts of using the psychrometric chart.
