Refrigeration Fundamentals For HVACR Technicians
In this 90-minute video presentation, well-known author and instructor Jim Johnson eliminates the mysteries behind the concepts of vapor compressor refrigeration systems. The program begins with a brief overview of thermodynamics, sensible and latent heat concepts, and the basic components of a refrigeration system before taking a nuts-and-bolts approach to understanding and servicing residential and light commercial equipment.
Using cutaways of components and refrigeration systems to demonstrate, Jim explains and shows how refrigeration systems applied to comfort cooling systems, as well as those found in other systems such as walk-in coolers and freezers, reach-in’s, and other applications.
The accompanying resource material CD includes an interactive resource guide, quiz questions, additional information on EPA refrigerant recovery certification, sample questions and an answer key for EPA certification and additional temperature/pressure charts.
