The Refrigeration Basics CD, the first module of the company's distance learning training program, serves as an introduction to the refrigeration process. Topics covered are the refrigeration system and its components, an introduction to compressors, Copeland compressor products, and compressor performance. Each chapter of the CD features a voiceover, which reviews the material, as well as more detailed information that the user can navigate through. A user's guide aids students with the program. At the end of the session, students must take a quiz to see how well they absorbed the material, the company states. If the student scores an 80 percent or higher, the manufacturer will send the student a certificate of completion, upon the student's request.
