No need for a refrigerator. Is it better to turn off the electricity or turn it on?

It is not recommended not to cut off the power supply for a long time. Because the plastic in the refrigerator liner is easier to age at normal temperature than at low temperature, keeping the low temperature uninterrupted can slow down the aging phenomenon and relatively prolong the life of the refrigerator. In addition, when the refrigerator is shut down, the unused refrigerant in the refrigerator will directly corrode the pipeline of the refrigerator, leading to the leakage of the refrigerator.

Common sense of refrigerator

First, the dividing point between air cooling and direct cooling is about 300 liters, and large-volume multi-room air cooling has advantages.

Second, it has a large volume and many rooms. Air cooling has an absolute advantage in cold energy distribution. If direct cooling is adopted, there will be technical obstacles and it will be difficult to achieve. The number of directly cooled rooms has basically reached the limit. If you want to make more rooms, you have to sacrifice some performance.

Therefore, when you see some large-capacity direct-cooling refrigerators with multiple rooms (even drawer doors) on the market, don't believe it. This kind of products are not uncommon in the market, mostly concentrated in small brand products, mainly sold in the third-and fourth-tier markets. It can also be seen around some big cities and in home appliance wholesale markets.

Third, the air-cooled refrigerator has more fans to supply air, so the indoor temperature of the refrigerator is relatively average, and there is no great temperature change, so the cooling effect is naturally excellent. However, considering the function of the fan and the complicated circuit design, the energy consumption and noise of the air-cooled refrigerator are much higher than that of the direct-cooled refrigerator.
