• Heat transfer and its application to evaporators and condensers;
• Gas compression and types of compressors;
• Refrigerant flow in pipes, valves and pumps;
• The operation and application of expansion valves;
• Pressure vessels and refrigerant management;
• Selection of refrigerants;
• Refrigeration system control;
• Product cooling and freezing loads; and
• Liquid cooling and space cooling loads.

Course Content

• Introduction to Refrigeration -- Types of refrigeration systems; major processes of vapor-compression refrigeration; and the field of refrigeration.
• Thermodynamics Fundamentals -- Thermodynamic properties of fluids; thermodynamic laws and applications; and energy calculations.
• Single- and Two-Stage Refrigeration Cycles -- Single-stage ideal refrigeration cycle; two-stage ideal refrigeration cycle; refrigeration system performance parameters; and deviations of actual refrigeration systems from ideal systems.
• Evaporators -- Psychrometrics of moist air cooling; air cooling evaporators and liquid cooling evaporators.
• Compressors -- Reciprocating, rotary screw, rotary vane, scroll and centrifugal compressors.
• Condensers -- Condensation processes; and air-cooled, water-cooled and evaporative condensers.
• Refrigerant Flow in Pipes, Valves and Pumps -- Fluid flow in pipes; valve and pipe fitting equivalent length; and pumps.
• Expansion Devices -- Pressure control valves; thermostatic expansion devices; electronic expansion devices; hand expansion valves; 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 -- Selection of refrigerants; classification of refrigerants; saturation pressure and temperature for refrigerants; safety of refrigerants; and codes and standards.
• Refrigeration System Types -- Direct expansion systems; flooded systems; recirculation systems; unitary systems; and field-erected systems.
• Refrigeration System Control -- Basic measurements, instrumentation and control; system control for safety; system control for capacity; and refrigerant flow control.
• Product Cooling and Freezing Loads -- Cooling food products; freezing food products; food freezing equipment; and cooling liquid food products.
• Liquid and Space Cooling Loads -- Cooling Secondary fluids; space cooling loads; and ASHRAE climatic data.
