Psychrometric Chart Fundamentals and its application to HVAC Trouble shooting

File Size: 1.04 Mb

Description

If HVAC problems and challenges are to be properly diagnosed and designed, it is essential that the Psychrometric chart and psychrometrics in general be clearly understood. This course will review the essential elements of psychrometrics (the behavior of mixtures of air and water vapor under varying conditions of heat) and the chart that represents it. With this knowledge, you will be able to understand many of the HVAC challenges that are certain to arise, as well as anticipate problems before they occur and incorporate in your design.

Like many self-study courses, you will only get as much from it as you put into it. Plot each step on your own psychrometric chart. Be certain you understand the basics before studying the examples. Try to solve the examples for yourself. This is not the type of course you can just read through and take the Quiz – it will take effort. But if you do your best, you should be able to pass the Quiz with ease – whether beginner or advanced.
