2. Cold air is the magic weapon to keep the refrigerator fresh. The reason why the refrigerator can keep fresh for a long time is to extend the storage time of food in the refrigerator by cold air. In the process of using the refrigerator, we must pay attention to minimize the leakage of cold air. Do not open the refrigerator door for a long time or frequently, so that the temperature in the refrigerator will be maintained at a relatively low level, and the compressor will not need to work for a long time, increasing unnecessary power consumption.
3. The temperature of the refrigerator should be set at different temperatures according to different seasons, so as to ensure the refrigeration effect of the refrigerator and the service life of the refrigerator compressor. Usually it is adjusted to 1.2 in summer, 3 in spring and autumn and 4.5 in winter.
4. Defrosting can effectively improve the refrigeration efficiency of refrigerator and reduce power consumption. At the same time, there are a lot of odors in the frost, so timely defrosting can effectively control the odor in the refrigerator. There are also many ways to defrost. Simple natural defrosting method: unplug the power supply and open the refrigerator door, so that the temperature in the refrigerator rises and the frost melts naturally. Quick-melting defrosting method: unplugging the power supply and placing a heat source (such as hot water) in the refrigerator can speed up the defrosting process. Physical removal method: unplug the power supply and remove the frost one by one with a plastic shovel that does not harm the refrigerator. Under normal circumstances, defrosting should be considered when the frost body is larger than 5 mm
1. The principle of the refrigerator is to use refrigerant to exhaust the hot air in the refrigerator outside, so as to keep the interior low. If the outdoor temperature is too high, the heat dissipation efficiency of the radiator will certainly not be too high, and the internal temperature of the refrigerator can not reach the required temperature. At this time, the refrigerator will continue to work until it reaches the predetermined temperature. In this way, it takes 1 hour to reach the temperature at low temperature, and it may take 2-3 hours of continuous work to complete at high temperature, so the power consumption will also increase obviously.
2. The working principle of refrigerator is to take away heat through the exchange of refrigerant liquefaction and gasification, so as to achieve the purpose of reducing the temperature in refrigerator. When the temperature in the refrigerator reaches a predetermined value, the compressor of the refrigerator stops working and is in a standby state (at this time, the power consumption is less), so the temperature in the refrigerator can be effectively maintained at a low level, and the frequent operation of the compressor is reduced, thereby reducing the power consumption.
3. If there is a problem with the adjustment of user parameters, the compressor will start and stop frequently. For example, in the cold winter, when the user adjusts the temperature of the refrigerator to the spring and autumn temperature, the compressor will stop working. At this time, if the temperature in your refrigerator does not reach the normal refrigeration temperature, the compressor will receive the instruction to continue working, and there will be a situation where it is required to stop while working. The compressor itself will start and stop frequently, which not only has a good refrigeration effect, but also has a good power saving effect.
The lower the temperature in the refrigerator, the later the frost layer. According to the different material properties, the thermal conductivity of frost is much smaller than that of metal, so too thick frost layer will seriously affect the evaporation efficiency and refrigeration effect of evaporator, and will increase the refrigeration time and power consumption of refrigerator innocently.
