The Refrigeration & Air Conditioning Basics Certificate Course is designed to teach the fundamental working principles of refrigerators and air conditioners. This HVAC course uses graphics and detailed animation to deliver a clear understanding of the refrigeration cycle and the air conditioning cycle.
Detailed explanations of Dry Bulb, Wet Bulb, Dew Point Temperatures, coefficient of performance (CoP), heat rejection factor (HRF), Sensible & Latent heat, Mollier diagram and the Psychrometric chart, making this a comprehensive course on refrigeration and Air Conditioning Basics. Refrigeration and air conditioning components are covered in detail too. HVAC components like compressors, evaporators, condensers, throttling valves, fans, piping, insulation, etc. These details make the downloaded version of this HVAC certificate course, you keep a great reference to assist in refrigerator repair and AC repair & maintenance.
- Yes, it is Air Conditioning & Refrigeration Cycle Basics, but it is in-depth coverage.
- Both the vapour compression cycle and absorption refrigeration cycle are covered.
- This certificate course is for anyone requiring knowledge on Refrigeration and Air Conditioning Systems.
- Includes extensive 2D / 3D graphics, animations, skill tests, and certificate printout.

Who Can Benefit:
The details described above in guided tour, show this training course makes for a completely comprehensive guide to aid in AC and Refrigerator Repair. Students, as well as maintenance and engineering personnel who have not had formal training, will find this course very helpful. Those in process and manufacturing and those in building trades industry, such as electrical engineers, plumbers and mechanics who are likely to be involved with refrigeration and air conditioning systems and controls, wanting to understand refrigeration and air conditioning systems basic operation.
Also instructors and corporate training directors wanting to supplement their own HVAC course or even design a course around this material. Industrial and building maintenance, electricians installers and engineers may have a need for this course. As well as Boilermakers, Plumbers, Pipefitters, and Steamfitters, even Solar photovoltaic (PV) installers may have need. This refrigeration training course is a great starter for those interested in becoming an HVAC mechanic, HVAC contractors apprentice, installer or an AC repair technician working for an air conditioning contractor.
