The function of the refrigerator is to keep fresh, but the temperature is too high to keep fresh. If the temperature is lowered, the preservation effect is good and the preservation time is long. Generally, the refrigerator is 2-6 degrees. At the same time, it is also necessary to consider whether the refrigerator can operate normally. When the room temperature is very low in winter, it is required to adjust the temperature in the refrigerator below the room temperature, otherwise it cannot be started. Therefore, it is suggested to change to gear 5-7 in winter, 1-3 in summer and 3-5 in spring and autumn. Don't just think about saving electricity.
Tips for saving electricity in refrigerator
1, reduce the number of times and shorten the opening time.
Every time the refrigerator is turned on 1 min, the temperature in the refrigerator will generally rise 1℃, which is not conducive to power saving. Setting plastic film door curtain in refrigerator can solve this problem.
The temperature in the refrigerator is well regulated.
In summer, setting the temperature of the refrigerator freezer at 5℃ consumes more than ten degrees per month than setting it at 8℃, and the heat preservation effect is poor. The general food preservation effect is 8- 10℃. The freezing room temperature of-14℃ is about 2% lower than that of-18℃. (3) The stored food should not be too full or too tight, and there should be a gap of more than 100mm between the food and the box wall, which is beneficial to the convection of cold air in the box, so that the temperature in the box is uniform and stable, and the power consumption is reduced.
It is very important to defrost regularly.
Although there are frost-free refrigerators now, some refrigerators are still frosted. Generally, if the frost layer on the evaporator surface of refrigerator is more than 5 mm, it will be defrosted. If the frost layer is too thick, it will produce great thermal resistance, affect cold and heat exchange, have poor refrigeration effect and increase power consumption. So it needs to be cleaned regularly.
4, the refrigerator should be selected
Generally speaking, people need a refrigerator with an average volume of 50-70L. According to the size of the family, it is appropriate to choose a refrigerator suitable for your family. At the same time, after determining the capacity, it is best to give priority to the energy-efficient refrigerator.
5, the correct use of refrigerator thermostat
In some mechanical temperature-controlled refrigerators, it is necessary to use the thermostat on the refrigerator correctly and adjust the temperature according to the actual needs (variety and time) of storing food. Generally, reducing the midrange can save electricity.
