It is not recommended to power off the refrigerator after it is not used for a long time. If the refrigerator is not used for a long time, the refrigerant oil and refrigerant of the refrigerator will deposit at the bottom of the compressor and the bottom of the pipeline, and the refrigerant is corrosive, so the refrigerant oil can play a neutralizing role. Once the refrigerator is not used for a long time, the refrigerant will quickly corrode the pipeline due to the lack of refrigerant oil protection, which will damage the internal functions of the refrigerator. Of course, if it is not used for a long time, the power can also be disconnected. Here, we need to remind you that when it is not used, the refrigerator must be powered on once half a month or once a month, and the power on time is about 2 to 4 hours. In this way, the refrigerator can be maintained and protected from damage.
How to adjust the temperature of the refrigerator?
At present, most of the temperature regulators of household refrigerators on the market are usually installed in the refrigeration room. The temperature regulation grades are divided into eight grades from 0 to 7. The higher the value, the lower the temperature of the refrigerator. Accordingly, the better the refrigeration effect of household refrigerators is. The refrigerator in gear 0 will enter the standby state, the compressor will not work, and the refrigerator in gear 7 will enter the efficient refrigeration state, and the temperature in the refrigerator freezer will drop to the lowest. When adjusting the temperature, you only need to open the door of the refrigerator freezer, turn the temperature setting pulley or the button to adjust the temperature, which is very convenient.
It should be reminded that when setting the temperature of the household refrigerator, it should not be too high or too low. If the temperature of the refrigerator is set too low, it is easy to freeze the food into ice. It will be troublesome to take it out again for consumption. It will not only require re icing the food, but also greatly increase the power consumption of the refrigerator. If the temperature of the refrigerator is set too high and can not achieve good fresh-keeping and freezing effect, it is usually the best to set the temperature of the refrigerator freezer at about – 18 ℃. In this way, the problem of freezing and frosting will not easily occur inside the refrigerator, and its energy efficiency can be maximized. The temperature of the refrigerator can effectively fresh-keeping food when it is set between 0 ℃ and 10 ℃.
