Refrigerator maintenance way:regularly defrost, clear the condenser and box body surface dust, to ensure the evaporator and condenser good heat absorption and heat dissipation performance, shorten the compressor working time, save electricity. Under the premise of ensuring the quality of food, the thermostat should be adjusted reasonably according to the seasonal changes, food types and quantities, 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 the food inside to reduce the loss of cold energy. Refrigerator power saving method [1] some refrigerators in the upper front of the refrigerator have aluminum strip, can be used to press a layer of non-toxic plastic film, its width and length are longer than the refrigerator door 15 cm. after as long as open the corner of the plastic film, you can take and put food, can make the refrigerator keep low temperature. 【2】In the cold storage of each grid in front of a layer of non-toxic transparent plastic film than the grid is slightly larger, can reduce the loss of cold air. 【3】When there are not many items in the refrigerator, filling foam blocks in 1 ~ 2 compartments can shorten the working time of the refrigerator. By taking the above measures, the refrigerator can save electricity about 10 degrees per month. 【4】Refrigerator placement:Refrigerator should be placed in low ambient temperature, well-ventilated place, away from heat sources, avoid direct sunlight, the top of the refrigerator and back left and right sides should be left with appropriate empty room, to facilitate heat dissipation. Refrigerator should be placed in a cool and 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, smelly and corrosive items (such as fish, acid and alkali, vegetables, fruits, etc.) Need to keep fresh and dry, sealed with plastic film or other packaging materials, shall not be stored in the refrigerator. 【6】Take and put the way of food:Take and put the food when try to reduce the number of times and time to open the door, quickly open and close the door, try to open the door at a small angle, try to have a plan to take out or put in the food, avoid too much heat into the box. Prohibit to put hot food in the refrigerator, because the heat content of hot food is relatively high. After putting into the refrigerator, the temperature inside the refrigerator will rise sharply, meanwhile the thickness of the frost layer on the evaporator surface will increase, the compressor will work too long and the power consumption will increase. Refrigerator storage of food to be sufficient, not too full or too tight, will affect the convection of air inside the refrigerator, so that the food is difficult to heat, affecting the effect of food preservation. At the same time will increase the working time of the compressor, increase power consumption. Vegetables, fruits and other water more food should be washed and drained, wrapped in plastic bags into the refrigerator, reduce water evaporation, thicken the frost layer, shorten the defrost time, save electricity. 【7】 Do not open the refrigerator for a long time, and do not frequently open the refrigerator door, so that the refrigerator open time to short, the number of times to less, open the angle to moderate, can reduce the loss of cold air in the cabinet, is conducive to energy saving. 【8】find water leakage timely replacement door seal, avoid cold air from the door seal gap loss, refrigerator lose refrigeration insulation function. 【9】 also need to consider whether the refrigerator should have the function of intelligent frost, because the water in the refrigerator from the water content of food and open the door into the refrigerator when the moisture in the empty air, condensing into frost on the evaporator. The lower the temperature inside the refrigerator, the faster the frosting rate and the thicker the frost layer. The heat transfer of the frost layer is slower than the metal, which will hinder the cooling effect of the evaporator and increase the power consumption. Therefore, there is no automatic defrost refrigerator, when the thickness of the frost layer on the evaporator more than 4 ~ 5 mm, should be timely manual defrost. [10] frozen food should be put into the freezer to melt before consumption, which can reduce the temperature of the freezer and save electricity. [11] Cooked food should be cooled to room temperature before putting into the refrigerator. [12] Don’t put food intensively in the refrigerator, leave empty gaps between stored foods so that cold air can be convected and the temperature can be even. Using small packages can reduce the cold penetration time, save electricity and facilitate access. [13] always pay attention to the refrigerator & ldquo bath & rdquo, the surface of the compressor and condenser should be cleaned once every two to three months. The more dust accumulation, the worse the heat dissipation effect, the more power consumption. Unplug the power plug, wipe with a damp cloth. [14] After the refrigerator compressor stops, the suction side and discharge side keep a large pressure difference. If started immediately, the compressor piston pressure will increase, which may burn out the motor. So, in case of power failure, unplug the power or turn off the machine. Temporary power failure also takes 3-5 minutes to start. 【15】Adjusting the thermostat is the key to saving electricity in the refrigerator. In summer, it should be adjusted to 4 or the highest, to avoid frequent start of the refrigerator and increase power consumption. Without cooling, it is forbidden to put hot food into the refrigerator. Vegetables, fruits and other food with more water should be washed, drained and put into the refrigerator to reduce water evaporation and thicken the frost layer. This can shorten the defrosting time and save electricity.
