How a Walk-In Freezer Works

Commercial freezers use the same principles as your freezer at home. Although you may think of cold air circulating in the unit, it is really energy — in the form of heat — that transfers from hotter areas into colder areas. In this case, heat above the freezer’s set point is removed from the insulated space, making it colder inside.

When the temperature inside of the unit rises above the set point of the freezer, refrigerant gets triggered and enters the compressor as a low-pressure, low-temperature gas. When the refrigerant compresses, its temperature rises. This higher temperature gas then passes to the outside of the unit, releasing excess heat through radiation and lowering the temperature of the refrigerant. The gas continues on, passing through an expansion device that releases pressure, forcing its temperature lower and causing it to change into a liquid state. The cooler refrigerant passes to the inside of the freezer, absorbing excess heat. The process continues to cycle until the unit reaches its set point.
