This course introduces the students to the physics of the basic refrigeration cycle, refrigerants, the pressure and temperature relationship, and pressure-enthalpy. 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 and Low GWP guidelines, identify refrigerants, and determine the temperature application.
