Introduction to Refrigeration Systems
Course Highlights

This online engineering course provides necessary information to understand the principles and theory of refrigeration, the components of mechanical refrigeration systems, and the types of refrigerants and associated equipment. This course also discusses the methods used for installing, maintaining, and repairing refrigeration equipment, including domestic refrigerators and freezers.


Refrigeration is the process of removing heat from an area or a substance. It is usually done by an artificial means of lowering the temperature, such as by the use of ice or mechanical refrigeration, which is a mechanical system or apparatus, designed and constructed to transfer heat from one substance to another.
