Currently, refrigerators are indispensable appliances in almost every family. The device operates continuously 24/7, in both summer and winter, helping to preserve and store family food to stay fresh longer. However, because it operates continuously, the refrigerator is also listed as one of the most energy-consuming devices in the house. Few people know that there is a small button in the refrigerator that users should adjust in the winter to help save “basic” electricity.

Statistics from Vietnam Electricity Corporation (EVN) in May showed that a large refrigerator consumes an average of 50 – 75 kWh of electricity per month, ranking third among household appliances, after electric stoves and water heaters.

In fact, the above figure is only an average. During the usage process, there are user habits that can help save some of the electricity consumed by the refrigerator. Especially in the dry season, this only needs to be done with 1 simple operation with 2 compartments – the dry compartment and the cool compartment of the refrigerator. However, not many users really know and pay attention to this operation. That is the operation of adjusting the temperature with the knobs or display panel of the refrigerator.

With just 1 small adjustment operation with the refrigerator in the winter, the family’s electricity bill can be saved somewhat. Refrigeration experts say that in the winter, to save electricity, users can consider adjusting the temperature of the refrigerator to a lower cooling level. Specifically, in modern refrigerators today, the temperature inside the refrigerator will be regulated at levels 1-5 or 1-6.

In the summer, the temperature can be at maximum or near maximum, but in the winter, adjusting the temperature to level 2-3, or even 1 is completely possible. At level 1, the temperature in the refrigerator will usually fluctuate from 2-5 degrees Celsius. This is the appropriate temperature level for the refrigerator to operate well, complete all the tasks of storing and preserving food, and help the refrigerator save electricity. This can also be done similarly with the refrigerator compartment.
