Module two, Fundamentals of Air Conditioning and Refrigeration, consists of three sections: Basic Refrigeration Principles; Refrigerants; and the Refrigeration Cycle.

Module three, Compressor Operation and Mechanical Failures, consists of six sections dealing with the five most common causes of compressor failures, including how to analyze failed parts to determine the root cause of a problem. The six sections include: Fundamentals of Compressor Operation; Refrigerant Floodback; Flooded Starts; Slugging; Overheating; and Loss of Oil.

According to Emerson, these modules are ideal for brushing up on the basics or helping prepare contractors who plan to attend an instructor-led course. Each session takes about 20 minutes to complete. At the end of the session, students must take a quiz. If a student scores an 80 percent or above, Emerson will send them a certificate of completion upon request.

"Through our distance-learning modules, we're bringing the classroom to the contractor, making it easier than ever for students to continue their educations," said Banas. "Student interaction is the key to maximizing learning in this format, and all three of our distance-learning modules are successful at doing so."
