In recent years, everyone has heard the word energy saving and environmental protection the most. The harsh air environment makes us realize the importance of energy saving and environmental protection. Summer is the season when electrical appliances are used most frequently, and the power consumption is also increasing, so we are choosing An energy-saving refrigerator is very important. What issues should we pay attention to in the selection process?
Baili freezer experts said that the core of freezer energy saving is the compressor, and the compressor is not always running. When the inside of the freezer reaches the required temperature, the compressor will stop working. Therefore, the energy efficiency of the compressor directly affects the energy-saving effect. The higher the efficiency of the compressor, the shorter the working time and the lower the power consumption of the same items.
So how to judge the quality of the compressor? It can be basically judged from the current national compulsory refrigerator energy efficiency standard. According to the mandatory national standard GB12021.2-2003 "Limited value of power consumption and energy efficiency of household electric refrigerators" "Class" stipulates that the energy consumption of products is from low to high. The energy efficiency of electric refrigerators is divided into 5 levels, 1, 2, 3, 4, and 5. The smaller the number, the higher the energy efficiency level and the more energy-saving.
In addition, the specific method for judging whether the compressor is good or bad is: after the electric refrigerator is connected to the power supply, the sound of the start relay contact closure can be heard, and then the running sound of the compressor can be heard. Note that when the compressor starts to rotate, no abnormal mechanical sound should be heard; with the increase of the compressor rotation time, the compressor should emit a clear, uniform and smooth running sound, and the sound should gradually decrease; the compressor stops There should be no abnormal sound at the time. When the compressor is running, you can feel a slight vibration when touching the compressor by hand, but when the back of your hand touches the casing, the casing should not be too hot. In addition, the compressor should enter a stable working state after normal operation for about 20 minutes.
Of course, the energy saving of the freezer is not only related to the performance of the compressor, but also the loss of cold air in the freezer. The serious loss of cold air in the freezer will cause the internal temperature of the freezer to be too high. The temperature sensor of the freezer will issue instructions to start the compressor frequently, causing unnecessary power consumption. The most serious loss of air-conditioning in the freezer is opening and closing the door, especially in the summer when you often need to take things such as ice cubes and drinks. Frequent opening and closing of the door will lose a lot of air-conditioning.
In addition, when the weather is hot, it is best to adjust the refrigerator to 5 degrees Celsius and the freezer to minus 14 degrees Celsius. The freezer should be placed in a place with low ambient temperature.
