How a Walk-In Cooler Works

Commercial refrigerators are typically insulated cold storage spaces that maintain a temperature of 35-41°F. When the temperature inside of the unit rises above the cooler’s set point, refrigerant enters the compressor as a low-pressure, low-temperature gas from the exterior of the unit. As the refrigerant compresses, its temperature increases proportionately. The gas then passes to the exterior of the unit, radiating excess heat and reducing the refrigerant’s temperature. The refrigerant next passes through an expansion device that relieves its pressure and decreases its temperature, causing it to change state into a liquid form before crossing into the interior of the unit. The now-cooler refrigerant absorbs heat from the insulated space and begins the process again until the unit reaches its desired set point.
