Whenever we pay the electricity bill, we will think of several "big electricity consumers" in the family, that is, air conditioners, refrigerators, and water heaters. As for how much electricity they consume, it is impossible to know without details. Look at the manufacturer's manual, the manufacturer's basic label is the rated power, and the actual use is very different. In order to better publicize the power saving, the comprehensive energy consumption marked by the merchant is somewhat watery. In particular, refrigerators are listed as large power consumers, in fact, as long as they are used correctly, they may not consume much electricity.
The most power-consuming component of the general household refrigerator is the refrigeration compressor, and its rated power generally does not exceed 200W. The power of the refrigerator will generally not exceed 300w. If calculated according to this value, it also needs to consume 4-7 kilowatts of electricity for 24 hours a day. But in actual use, the refrigerator will certainly not always run at the rated power. Therefore, many merchants will give another indicator, that is, comprehensive power consumption. The refrigerators on the market are generally about 400L, and the comprehensive power consumption advertised by the merchants is about 1 kilowatt. Of course, in order to promote power saving, this value is somewhat watery.
Every family or everyone, the refrigerator is placed differently, and the frequency of using the refrigerator is also different. The resulting power consumption will be different. In general, the refrigerator is divided into a cold room and a freezer room. The cold room is mainly used for preservation, and the temperature is around 3 ° C. The freezer is generally used for freezing, and the temperature is about -18 ° C. Compared with the indoor temperature, the temperature difference between the two is different, resulting in the energy wasted by the door of the open freezer room being more power-consuming than the door of the open refrigerator. At the same time, the higher the temperature of the things placed in the refrigerator, the greater the power consumption; the higher the frequency of the refrigerator opening, the greater the power consumption.
Normal office workers, the refrigerator stock will not be a lot of food, and only at home to cook dinner. In this case, the refrigerator of about 400L consumes about 2-3 kilowatts of electricity a day. If there are elderly people and children at home, there are more refrigerated foods every day, and three meals are made at home, and there are more refrigerator doors open and closed. In this case, it is expected that the power consumption of the refrigerator will go to 4-5 kilowatts a day.
Combined with the above situation, if you want to save electricity, you must pay attention to the following details:
Reduce unnecessary refrigerator doors, especially freezer doors;
The side of the refrigerator is generally a heat dissipation surface, do not get close to other high heat sources, and do not get too close to the wall (generally recommended to be greater than 25cm);
Foods that are too high in temperature should not be placed directly in the refrigerator, and should be cooled naturally before being put in;
Refrigerators that will freeze, be sure to remember to de-icing regularly;
Although household electricity is not very expensive, it can also be regarded as a contribution to the national industrial development and environmental protection and energy conservation.
In short, the refrigerator power rating is relatively high, and the actual power consumption is related to personal use habits. If you don't want your refrigerator to consume too much power, you should really pay attention to the precautions for the use of refrigerators.
