Regularly defrosting the freezer is an important process to maintain the efficiency of the appliance and reduce the electricity bill. The layer of ice that forms inside can have various effects on the efficiency, lifespan and, above all, on the consumption of the device. Find out why defrosting the freezer saves energy and how you can do it quickly without having to unplug it.
Why should the freezer be defrosted regularly?
Regular defrosting of the freezer is an important operation to maintain the efficiency of the appliance and avoid high energy consumption. This operation, if carried out correctly, would save 30% in consumption for each half centimeter of frost removed. Here are the reasons.
Reduce energy consumption
The layer of ice that forms inside the freezer is several centimeters thick and can reduce the efficiency of the motor, making it work harder and therefore use more energy. This is because the ice layer acts as a barrier to the flow of heat from the outside environment to the motor, causing it to increase speed to maintain the desired temperature in the freezer. Additionally, the thermal resistance of the freezer walls increases, making it more difficult to transfer heat from the external environment to the interior of the appliance. By removing excess ice, the motor runs more efficiently and uses less electricity.
Avoid overheating
Since the layer of ice inside the freezer prevents proper heat exchange with the outside environment, the motor may overheat. If the motor overheats, its efficiency decreases and energy consumption increases. Additionally, overheating can damage the motor and shorten the life of the device. Therefore, by defrosting the freezer, you prevent the motor from overheating and protect the appliance from damage that can occur due to excessive heat.
