REFG 102 is a lecture-lab combination course. Students will spend time both in theory lectures using academic course materials and in lab settings applying skills learned in theory. This course will provide an in-depth study of the four essential components of the refrigeration system: evaporators, condensers, compressors, and metering devices. Normal system operating conditions will be discussed for a variety of refrigeration and air conditioning applications. Understanding normal operating conditions will be essential in learning troubleshooting techniques. This course will begin with a review of the theories of refrigerants, refrigerant recovery methods, and system evacuation. This class may require participation in several field trips for further understanding of the profession.
