Advanced-level course providing refrigeration system operators, refrigeration journeymen, refrigeration service, and maintenance technicians with a comprehensive review in preparation to take a 1st, 2nd, or 3rd Class Refrigeration Operator License exam, the Refrigeration Journeyman License exam, similar related exams or to prepare for commercial or industrial refrigeration operation and maintenance positions. Covers the fundamentals of refrigeration, identification, and functions of various refrigeration systems and equipment with special commercial and industrial refrigeration systems covered on the license exams. Access to computers is critical for the mandatory computer-aided field research which requires visits to current refrigeration industry web sites. Students must be computer literate with web browsers, word processing, spreadsheets, e-mail, and other computer-online activities. Laboratory activities. May require field trips. NOTE: License exams are not included in this course.
