Hiring the Best Portland Walk in Cooler Repair

While walk-in coolers are widely thought to function the same way as household refrigerators, these two forms of cooling systems actually act in somewhat different ways. Refrigerators use the cool air the freezer produces inside them to hold the area of the refrigerator safe. Have a look at Portland Walk in Cooler Repair for more info on this.Walk-coolers produce the cold air they need to hold the air at the temperature the thermostat is adjusted at, use fans and a condenser that turns on and off to regulate the unit ‘s temperature. And the equipment that runs a walk-in cooler is more analogous to a refrigerator to the way an air conditioner functions.

The Thermostat and the Condenser Machine
For a walk-in cooler it’s the thermostat that sets the temperature. Once the temperature within the device begins to increase past the temperature at which the thermostat is set, the condenser turns on and a new cooling process starts. And the fans in the machine draw air through the condenser’s cooler and over its coils. The refrigerant inside the coils extracts the heat from the air as it flows through them. The cooled air instead passes out the unit’s back, which becomes a little cooler than when brought in. This persists until either the air temperature approaches or becomes cooler than the thermostat value. During the cooling cycle, the coolant in the condenser coils is continuously pumped; this means that the coolant will not heat up too much before refreshing again.

Another process means the condenser does not freeze and is coated with ice and snow. If the temperature drops so far (usually about 35 degrees Fahrenheit), the fans start over again, but without the coolant circulating through in the coils. It warms the condenser coils slowly, and the temperature begins to rise. When the temperature inside the cooler is back within the appropriate range, this defrost process should end.

Freezing
Their insulation is an essential element in an efficient walk-in cooler. Normal walk-in coolers have in their walls between 2 and 4 inches of Styrofoam insulation along with a rubber sealing gasket around the door which helps to ensure that it is both well-insulated and airtight. The Styrofoam and sealing gasket prevent outside temperatures from affecting the air inside the refrigerator, and insure that only the air within the device needs to cool the condenser.
