The ingenious trick to defrost a freezer: the ice disappears without having to unplug it

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 consuming more energy. In fact, the layer of ice hinders the flow of heat from the outside environment to the motor, forcing it to increase its speed to maintain the desired temperature inside the freezer. It also increases the thermal resistance of the freezer walls, making it more difficult to transfer heat from the outside environment to the inside of the appliance. Therefore, removing excess ice allows the motor to operate more efficiently and consume less electricity.

Prevent overheating
By preventing proper heat exchange with the outside environment, the layer of ice inside the freezer can cause the motor to overheat. When the motor overheats, its efficiency decreases and energy consumption increases. In addition, overheating can damage the motor and reduce the life of the appliance. Therefore, defrosting the freezer prevents the motor from overheating and protects the appliance from damage that can be caused by excessive heat.
