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.
Improves storage efficiency
The layer of ice inside the freezer can hinder the circulation of cold air, reducing its ability to preserve food. When cold air does not circulate properly, some areas of the freezer can become warmer than others, creating ideal conditions for bacteria to grow and food to spoil. Removing the accumulated ice ensures better circulation of cold air and therefore better preservation of food, thus avoiding food waste.
How often should you defrost your freezer?
The ideal time to defrost your freezer depends on the layer of ice that has formed inside the appliance. In general, it is advisable to do this when the layer of ice has reached a thickness of about 3-4 millimetres, as at this point energy consumption can increase by up to 30%. If the appliance is used frequently and the layer of ice forms quickly, it will need to be defrosted more often. Conversely, if it is used less often, the layer of ice will form more slowly and the frequency of defrosting can be reduced.
