What You Will Learn

You will develop an understanding of the field of refrigeration, including the three main areas: comfort cooling or air conditioning; commercial refrigeration; and industrial refrigeration. The 12 chapters build your knowledge from an understanding of basic refrigeration principles to their application in real-world situations. After completing the course, you should know:

  • The principles of refrigeration and thermodynamics
  • The components that comprise refrigeration systems
  • The different refrigeration cycles
  • The types of refrigerants available and their characteristics
  • The codes and standards related to refrigeration systems
  • The cooling and freezing of food products and the equipment needed
  • The refrigeration systems used in four example applications

Course Content

  • Fundamentals of Refrigeration - Types of refrigeration systems; major processes of vapor-compression refrigeration; heat-pump cycle; and the field of refrigeration.
  • Fundamentals of Thermodynamics - Thermodynamic properties of fluids; thermodynamic laws and applications; efficiency of refrigeration and heat-pump cycles; and energy calculations.
  • Multistage and Cascade Refrigeration Cycles - Single-stage ideal refrigeration cycle; two-stage ideal refrigeration cycle; cascade refrigeration cycle; refrigeration-system performance parameters; deviations of actual refrigeration systems from ideal systems; and refrigeration system types.
  • Evaporators - Psychrometrics of moist-air cooling; air-cooling evaporators; and liquid-cooling evaporators.
  • Compressors - Reciprocating compressors; rotary screw compressors; rotary vane compressors; scroll compressors; and centrifugal compressors.
  • Condensers - Condensation processes; air-cooled condensers; water-cooled condensers; and evaporative condensers.
  • Refrigerant Flow in Pipes, Valves and Pumps - Fluid flow in pipes; valve and pipe-fitting equivalent length; and pumps.
  • Expansion Devices - Capillary tubes and short tube restrictors; pressure control valves; thermostatic expansion devices; electronic expansion devices; hand expansion devices; level control valves; and turbo expanders.
  • Pressure Vessels and Refrigerant Management - Suction line accumulators; receivers; surge drums; flash tanks and intercoolers; and refrigerant inventory.
  • Refrigerant Selection - Types of refrigerants; saturation pressure and temperature of a refrigerant; refrigeration capacity and efficiency; safety of refrigerants; environmental impact of refrigerants; and codes and standards.
  • Product Cooling, Freezing Loads and Cooling Secondary Fluids - Cooling food products; freezing food products; food freezing equipment; cooling liquid-food products; and cooling secondary fluids.
  • Practical Guide to Refrigeration Systems - Refrigeration racks and display cases; refrigerated warehouses; system operation; meat processing; pharmaceutical refrigeration; and refrigeration.

Who Should Enroll in this Course?

This is an excellent course for anyone who needs information on refrigeration equipment and systems. You will benefit from this course if you are:

  • A recent mechanical engineering graduate who did not study refrigeration in college.
  • An experienced mechanical engineer or refrigeration technician who wants to increase their knowledge of refrigeration systems.
