The refrigeration cycle is basically the movement of refrigerant from one part of the refrigerator to the next and in different forms with the end goal of pulling down temperatures whether in a cabinet, counter or even cold room format.

The main importance of learning how your commercial fridge works is so that you understand how to clean and maintain equipment efficiently. E.g.: understanding that your fridge uses an air-cooled condenser (if it does) will help you find the ideal position for your unit in order to make its work easier and lower the energy consumption.

By understanding the basics, only then can one fully benefit from their commercial refrigeration.
