How to use a freezer more energy-efficiently: mastering the methods is very important.

In recent years, the term energy-saving and environmental protection has been heard the most. The deteriorating air environment has made us realize the importance of energy-saving and environmental protection. Summer is the season when electrical appliances are used most frequently, and the amount of electricity consumed is also increasing. Therefore, it is very important to choose an energy-saving freezer. What issues should we pay attention to during the selection process?

Experts from Baile Freezer state that the core of energy-saving in freezers is the compressor. The compressor does not run continuously; it stops working when the internal temperature of the freezer reaches the required level. Therefore, the efficiency of the compressor directly affects the energy-saving effect. When refrigerating the same items, the higher the compressor efficiency, the shorter the working time, and the less electricity consumed.

So how can we judge the quality of the compressor? The current mandatory national energy efficiency standards for freezers can basically determine this. According to the mandatory national standard GB12021.2-2003 "Limits of Power Consumption and Energy Efficiency Levels for Household Electric Freezers", the energy consumption of products is classified from low to high, with energy efficiency levels for electric freezers divided into five levels: 1, 2, 3, 4, and 5. The smaller the number, the higher the energy efficiency level and the more energy-saving it is.

Additionally, the specific method to judge the quality of the compressor is: after the electric freezer is powered on, you should hear the sound of the starting relay contacts closing, followed by the sound of the compressor running. Note that when the compressor starts to rotate, there should be no abnormal mechanical noise; as the compressor runs longer, it should produce a clear, even, and stable running sound, and the sound should gradually decrease; there should also be no abnormal sounds when the compressor stops. When the compressor is running, you can feel slight vibrations by touching it with your hand, but the outer shell should not be too hot when touched with the back of your hand. Additionally, the compressor should enter a stable working state after running for about 20 minutes.

Of course, the energy-saving of the freezer is not only related to the cooling effect of the compressor but also needs to pay attention to the issue of cold air loss from the freezer. If the cold air loss is severe, it will cause the internal temperature of the freezer to be too high, prompting the temperature sensor to issue commands that cause the compressor to start frequently, resulting in unnecessary energy consumption. The most severe cold air loss occurs when the door is opened, especially in summer when frequently taking out items like ice cubes or drinks, as opening and closing the door frequently will result in a significant loss of cold air.

In addition, during hot weather, it is most suitable to set the refrigeration compartment to 5 degrees Celsius and the freezing compartment to minus 14 degrees Celsius. The freezer should be placed in a location with a lower ambient temperature.
