Refrigeration has thus rapidly evolved since the early 20th century, from ice harvesting to temperature-controlled rail cars, refrigerator trucks, and ubiquitous refrigerators and freezers in both stores and homes in many countries.
All refrigeration systems work by transferring heat around, moving it from a designated area to somewhere else, thus cooling that designated area off and reversing the natural flow of heat with the application of energy. How this happens, however, varies among the four different types of refrigeration systems. [1]
Refrigeration is a vital part of our daily lives. Many aspects of life from food safety to medicine production to computer manufacturing all depend on refrigeration. But how does it work? In this article, we will explore the basic refrigeration cycle and its components.
