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.
