Speaking of household refrigerators, everyone must be very familiar with it. After all, in modern society, refrigerators have become one of the indispensable electrical appliances. So, have you really learned about refrigerators? I think most consumers' understanding of refrigerators is only limited to its refrigeration function. What are the refrigeration methods of refrigerators? What are the advantages and disadvantages of different refrigeration methods?
One, the refrigeration method of the refrigerator
1. Direct cooling refrigerator
Direct-cooling refrigerators are also called air-conditioning natural convection refrigerators. Its working principle uses the earliest refrigeration technology, mainly through cold air convection to achieve the effect of refrigerating food.

2. Air-cooled refrigerator
The working principle of an air-cooled refrigerator is similar to that of a household air conditioner. Generally, the cooling effect is achieved by the flow of air. The high-temperature air passes through the evaporator and the two will exchange heat. The surrounding air temperature will decrease, and the refrigerator will achieve the cooling effect. . In this way, after an infinite cycle, the entire process is the cooling process of the DC refrigerator. Finally, the fan is used to blow the cold air into the freezer and refrigerator, so the cooling effect will be better than that of a DC refrigerator.
3. Mixed cold refrigerator
As the name suggests, the mixed-cooling refrigerator is a combination of direct cooling and air cooling. Generally, the cold room uses the direct cooling type, and the freezer room uses the air-cooled type.
