Refrigerator maintenance mode: regular defrosting, remove the dust on the surface of the condenser and box, ensure good heat absorption and cooling performance of the evaporator and condenser, shorten the working time of the compressor, and save electric energy. On the premise of ensuring the quality of food, the temperature controller should be adjusted reasonably according to the seasonal change, the type and quantity of food, so that the refrigerator is always in the best working condition. In case of power failure, please reduce the frequency of opening the door and try not to put food inside to reduce the loss of cold energy. [1] Some refrigerators have aluminum strips on the front of the upper refrigerator, which can be used to press a non-toxic plastic film that is 15 cm wider and 15 cm longer than the refrigerator door. Then just open a corner of the plastic film, you can take food, can keep the refrigerator cold. [2] Clip a layer of non-toxic transparent plastic film slightly larger than the lattice in front of each cold storage, which can reduce the loss of cold air. [3] When there are not many items in the refrigerator, filling 1 to 2 compartments with foam blocks can shorten the working time of the refrigerator. By taking the above measures, the refrigerator can save about 10 degrees of electricity every month. [4] Refrigerator placement: The refrigerator should be placed in a place with low ambient temperature and good ventilation, away from heat source and avoid direct sunlight, and there should be appropriate empty rooms on the top and left and right sides of the back of the refrigerator to facilitate heat dissipation. The refrigerator should be kept in a cool, ventilated place, away from direct sunlight and heat sources. Because the high ambient temperature around the refrigerator will increase the power consumption of the refrigerator. [5] Pay attention to the physical and chemical properties of the items stored in the refrigerator. Flammable and explosive chemicals or drugs, odors and corrosive goods (such as fish, acid and alkali, vegetables, fruits, etc.) Need to keep fresh and dry, with plastic film or other packaging materials sealed, shall not be stored in the refrigerator. [6] Way of taking and putting food: when taking and putting food, try to reduce the number and time of opening the door, quickly open and close the door, try to open the door at a small Angle, try to take out or put food in a planned way to avoid too much hot air into the box. Do not put hot food in the refrigerator, because hot food is high in calories. After being placed in the refrigerator, the temperature in the refrigerator will rise sharply, and the thickness of the frost layer on the surface of the evaporator will increase. The compressor will work for a long time, and the power consumption will increase. The food stored in the refrigerator should be sufficient, not too full or too tight, which will affect the convection of the empty air in the refrigerator, so that the food is difficult to dissipate heat, affecting the preservation effect of food. Meanwhile, the working time of the compressor is increased and the power consumption is increased. Vegetables, fruits and other foods with more water should be washed and drained, wrapped in plastic bags and put in the refrigerator to reduce water evaporation, thicken the frost layer, shorten the defrosting time, and save electricity. [7] Do not open the refrigerator for a long time, or open the refrigerator door frequently. In this way, the opening time of the refrigerator should be short, the number of times should be less, and the opening Angle should be moderate, which can reduce the loss of air conditioning in the cabinet and is conducive to energy saving. [8] If water leaks, replace the door seal in time to avoid the loss of cold air from the gap of the door seal, and the refrigerator loses the refrigeration and insulation function. [9] It is also necessary to consider whether the refrigerator should have a smart frosting function, since the water in the refrigerator comes from the water content of the food and the water in the empty air that enters the refrigerator when the door is opened and condenses into frost on the evaporator. The colder the temperature in the refrigerator, the faster the frost formation and the thicker the frost layer. The heat transfer of frost layer is slower than that of metal, which will hinder the refrigeration effect of evaporator and increase power consumption. Therefore, there is no automatic defrosting refrigerator, when the thickness of the frost layer on the evaporator is more than 4 ~ 5 mm, manual defrosting should be timely. [10] Frozen food should be melted in the freezer before eating, which can lower the temperature in the freezer and save electricity. [11] Cooked food should be cooled to room temperature before being refrigerated. [12] Don’t pack food in the refrigerator. Leave empty Spaces between stored food so that the cold air can be convection and the temperature can be even. The use of small packaging can reduce cold penetration time, save electricity, convenient access. [13] Keep an eye on the refrigerator & shower, and the surfaces of compressors and condensers should be cleaned every two to three months. The more dust accumulated, the worse the heat dissipation effect, the more power consumption. Unplug and wipe with a damp cloth. [14] After the refrigerator compressor is shut down, the suction side and the discharge side maintain a large pressure difference. If started immediately, the compressor piston pressure will increase, which may burn the motor. So, in case the power goes out, unplug or turn it off. Temporary power outages can also take 3-5 minutes to start. [15] Adjusting temperature controller is the key to save electricity in refrigerator. In summer, it should be adjusted to 4 or the highest point to avoid frequent startup of the refrigerator and increase power consumption. Do not put hot food in the refrigerator without cooling. Vegetables, fruits and other foods with more water should be washed, drained and put in the refrigerator to reduce water evaporation and thicken the frost layer. This reduces defrosting time and saves power.
