ST. LOUIS - Emerson Climate Technologies launched the second and third modules of its distance-learning training program for contractors. The distance-learning training program is a series of interactive CD courses that allows HVACR contractors and technicians to learn at their own pace from their home or office. All three of the modules are offered through the company's Educational Services Division.

"Success in the HVACR industry requires a thorough understanding of the basics, while keeping on top of the latest trends and technologies," said Larry Banas, director of Emerson Climate Technologies' Educational Services Division.

The first module of the distance-learning series, Refrigeration Basics, was introduced in May 2005 and serves as an introduction to the refrigeration process. Upon completion of the CD, students have a general understanding of refrigeration basics and an appropriate foundation for the new modules.

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."
