Refrigeration engineering classes can be offered as part of undergraduate mechanical engineering programs at 4-year colleges and universities. They can also be found as part of heating, ventilation and air conditioning (HVAC) engineering technology certificate and 2-year degree programs, which are typically offered at community and technical colleges. These programs typically require lab work and hands-on practice with refrigeration systems components. Your coursework will include the following topics:
- Cost and location
- Heat absorption
- Safe handling
- Direct currents
- Cool air distribution
List of Courses
Principles of Refrigeration Course
Refrigeration is the process of transferring heat from air to make it cool. Refrigeration principles, such as vapor compression, heat absorption and cool air distribution, are introduced in this beginning refrigeration course. Hands-on laboratory experiments aid students' understanding of how refrigeration occurs. A portion of this course may be dedicated to safe use of refrigerants, which are chemical compounds used in the refrigeration cycle.
Thermodynamics of Refrigeration Course
The thermodynamic cycle and the concept of energy transfer, as they apply to refrigeration, are discussed in this course. Psychrometrics, the study of mixing air and water vapor, is introduced with psychrometric charts. These charts are used for calculating the amount of refrigeration needed to cool or warm a determined area. Thermodynamics is an advanced course for third- or fourth-year engineering students.
Design Engineering for Refrigeration Course
The design of refrigeration systems is based on many factors, such as cost, size and location. Students in this course use engineering principles to design and build components of a refrigeration system, based on one or more of these factors. A final project might include construction of a student-designed refrigerator. Thermodynamics of refrigeration is typically a prerequisite for this course.
Air Conditioning and Refrigeration Technology Course
This technical course is designed to teach refrigeration and air conditioning professionals the fundamentals of how air is cooled. Refrigeration cycles, thermodynamics and safe handling of refrigerants are discussed as refrigeration engineering techs learn to operate and test refrigeration systems.
Environmental Controls and Refrigeration Course
Section 608 of the Clean Air Act describes regulations regarding the proper use, reuse, recycling and disposal of refrigerants. Refrigeration technicians are required to understand Section 608 and pass a certification exam developed by the U.S. Environmental Protection Agency. This course educates students on rules regarding safe use of refrigerants in preparation for the EPA refrigerant exam.
Maintenance and Repair of Electric Refrigeration Components Course
This course begins with basic concepts of electricity, including circuitry and alternating and direct currents. Students learn about wiring refrigerators, fixing electric motors and using equipment to test electrical problems in refrigeration systems.
