Refrigeration Systems

A. Bhatia, B.E.

Most people think the refrigeration system’s job is simply to remove heat from an object. Actually there is no such thing “remove” the heat since heat is a form of energy than can’t be destroyed. We can only transfer heat from one place to another. Even though it is easier to think of refrigeration as the process of making things cold, it actually is the process of transferring heat from one place to another. It could also be said that refrigeration is the transfer of heat from one place where it is not wanted (walk in cooler), to another less objectionable place (outdoors).

This is just a very quick introduction to mechanical refrigeration system. This 4 -hour course provides more detailed information on the heat and refrigeration principles, refrigeration system components, type of refrigerants, methods of installation, maintaining, servicing and repairing the refrigeration systems.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
