For household appliances that require 24-hour power supply, it is important to save energy. Energy conservation not only saves electricity and saves money, but also contributes to the cause of environmental protection. It is really a good thing to do both. So, do you know how to save energy in the refrigerator? Refrigerator purchase First of all, when purchasing a refrigerator, it is best to choose a refrigerator product marked with a first-level energy efficiency label, and at the same time, according to the actual needs of the family, select the appropriate refrigerator volume size, and close the source at the source. Refrigerator placement There should be ventilation space around the refrigerator. Keep away from heat sources and place the refrigerator in a shaded place to avoid direct sunlight. Refrigerator cleaning If the frost thickness on the surface of the evaporator reaches 10 mm, the heat transfer efficiency is reduced by more than 30%, that is, the cooling effect is greatly reduced, so that the compressor is kept running and the power consumption is increased. Therefore, once the refrigerator is frosted, it needs to be cleaned in time. Refrigerator temperature adjustment According to the stored food, the temperature inside the refrigerator is properly selected, and the refrigerator controlled by the computer can be adjusted to the smart mode under normal circumstances. The mechanical temperature-controlled refrigerator and the thermostat are the key to saving power in the refrigerator. In summer, the thermostat knobs are generally adjusted to a high position, but in the winter, you can go to the lowest place. Open the door and avoid excessive frequency If the door is over-frequency, the power consumption of the refrigerator will be significantly enhanced, and the service life of the refrigerator will be reduced. When the door is opened, the light inside the box is turned on, which consumes both electric energy and a temperature increase, which is not conducive to energy saving. At the same time, we must try to shorten the opening time and number of times. Do not put hot food directly into it. Do not put the hot food directly into the refrigerator. When it reaches room temperature, it can be inserted again. This can reduce the workload of the refrigerator and save energy and electricity. Food should not be too full The food in the refrigerator should not be too full, and there should be a gap between the refrigerator and the wall of the refrigerator to facilitate the flow of cold air, generally up to 70% or 80%.
