This course introduces the physics of the basic refrigeration cycle, refrigerants, the pressure and
temperature relationship, and pressure-enthalpy to the student. The methods and principles associated with
evacuation, recovery and charging of refrigeration and air conditioning equipment are explored. At the
completion of this course students will be prepared to identify the main components in a refrigeration
cycle, use a pressure temperature chart, measure superheat and sub-cooling, plot a pressure-enthalpy
diagram, correctly recover, evacuate and charge an air conditioning or refrigeration system within
compliance of EPA608 guidelines, identify refrigerants, and determine the temperature application.
