The difference between direct cooling and air-cooled refrigerator

The difference between air-cooled refrigerator and direct-cooled refrigerator is as follows:1. Refrigerated air-cooled refrigerator adopts automatic air-feeding technology, which can cool food quickly and has a good cooling effect; direct-cooled refrigerator adopts convection technology, which is not as fast as air-cooled refrigerator.2. Noise. Air-cooled refrigerators are noisier than direct-cooled refrigerators and may produce more noise in use. If you like quiet, you should consider whether it is suitable to choose air-cooled refrigerator.3. Energy saving. Air-cooled refrigerators may consume more electricity. Compared with direct-cooled refrigerators, air-cooled refrigerators consume significantly more electricity, while direct-cooled refrigerators are more energy-efficient.4. Frosting characteristicsAir-cooled refrigerators are not easy to frost inside, and the food can be kept independently dry and will not stick together; straight refrigerators are prone to feel damp, and the refrigerator is prone to frosting, and the food is sticking to each other. Principle of air-cooled refrigerator:The principle of air-cooled refrigerator is to use air for refrigeration. When the high temperature air flows through the built-in evaporator (separated from the inner wall of the refrigerator), the air temperature will be lowered due to the high air temperature and the low evaporator temperature, both of which directly exchange heat. At the same time, cold air is blown into the refrigerator. The air-cooled refrigerator is to reduce the temperature of the refrigerator by this constant circulation. But there is always water vapor in the air, which condenses when it is cold, so as long as there is heat exchange in the refrigerator, there will be frost. Air-cooled refrigerators are not frost-free, but the frost condenses on the evaporator. Because it is inside the refrigerator, we open the refrigerator door is directly invisible, so it is called frost-free.
