Walk-In Coolers - learning All About Walk-In Coolers

Although it is generally believed that walk-in coolers work the same way as household refrigerators, these two types of cooling units truly control in very separate ways. Refrigerators use the cold air that is generated by the freezer within them to keep the refrigerator section cold. Walk-coolers generates the cold air that they need to keep the air the temperature that the thermostat is set at, using fans and a condenser that cycles on and off in order to profess the temperature of the unit. In this way the technology that operates a walk-in cooler is more similar to the way an air conditioner works than a refrigerator.

The Condenser Unit and the Thermostat
It is the thermostat that controls the temperature in a walk-in cooler. When the temperature inside the unit starts to raise above the temperature the thermostat is set at, the condenser unit switches on and starts a new cooling cycle. The fans in the unit then pull air inside the cooler and over the coils of the condenser. The coolant that is inside of the coils removes the heat from the air as it passes over them. The cooled air then moves out the back of the unit, and is a diminutive colder than when it was pulled in. This continues until the temperature of the air either matches or is colder than the temperature on the thermostat. The coolant in the condenser coils is constantly pumped while the cooling cycle; this makes sure that the coolant won't heat up too much before cooling down again.

There is another cycle that ensures that the condenser doesn't freeze up and come to be covered in ice and frost. If the temperature falls too low (generally nearby 35 degrees Fahrenheit), the fans start again, but without the coolant in the coils cycling through. This gently warms the condenser coils and the temperature starts to rise. This defrost cycle will stop when the temperature inside the cooler is back within suitable range.

Insulation
One leading factor in an productive walk-in cooler is its insulation. suitable walk-in coolers have between 2 and 4 inches of Styrofoam insulation within their walls along with a rubber sealing gasket nearby the door that helps ensure that it is both well-insulated and airtight. The Styrofoam and sealing gasket keep face temperatures from influencing the air inside the cooler, and make sure the condenser has to cool only the air that is inside the unit.
