In home appliance stores, we can often find that air-cooled and frost-free technology is widely used in refrigerator product promotion. At the same time, consumers do not need the function of defrosting. However, the author found that many consumers have a cognitive misunderstanding. At the same time, this point is also where manufacturers often hit the "stray boxing", that is, the confusion between the concept of "air cooling" and "full air cooling" of the refrigerator!  

 

To clarify this concept, we must first compare the difference between direct-cooled and air-cooled refrigerators! The disadvantage of traditional direct-cooled refrigerators is the need to manually defrost, which is also a major problem that has always plagued users. The application of technology in the refrigerator solves the problem of frost in the refrigerator. At the same time, "air-cooled frost-free" slogans of refrigerators, which are easy to spread, are frequently exposed, making consumers mistakenly believe that air-cooled refrigerators will not frost.

 

Attentive users will notice that some refrigerator companies use “full air cooling” to describe the air cooling technology of their refrigerators, and the meaning of “full air cooling” is very simple: each storage room (refrigerator, variable greenhouse) of a refrigerator , Freezer) all use air cooling technology, this can ensure that each storage room will not frost on the inner wall of the refrigerator, this is the correct interpretation of "full air cooling"!

 

Which of the direct cooling refrigerator and the air cooling refrigerator is good: the advantages and disadvantages of the direct cooling refrigerator

 

Advantages: The direct cooling refrigerator consumes relatively low power, and the evaporator is directly exposed to the cabinet, the cost will be lower, and the noise will be relatively small.

 

Disadvantages: Direct-cooled refrigerators have a slower cooling speed, which makes people feel inconvenient to use, and the evaporator is vulnerable to collision. Scratch. Corrosion, causing leakage and affecting life. The biggest disadvantage is that it has to be manually defrosted several times a year.

 

Which of the direct-cooled refrigerator and the air-cooled refrigerator is good: the advantages and disadvantages of the air-cooled refrigerator

 

Advantages: The air-cooled refrigerator will not frost like the direct-cooled refrigerator, so that the interior of the refrigerator is always wet, and the food will not stick to each other. In addition, the air-cooled refrigerator will have a continuous circulation of cold air, and then filtered by the deodorization system, the internal odor will be kept fresh for a long time. In addition, air-cooled refrigerators have more precise temperature control than direct-cooled refrigerators. Because direct-cooled refrigerators are prone to refrigeration dead corners, after all, the evaporator is attached to the cabinet, so the temperature of the temperature control point test may be different from the actual temperature inside the refrigerator, which will affect the quality of food preservation.

Disadvantages: Due to the continuous circulation of cold air inside the air-cooled refrigerator, the humidity of the air in the refrigerator will be lowered. If some foods are not isolated with plastic wrap or fresh-keeping boxes, they will easily run out of water and be dried. In addition, the internal structure of an air-cooled refrigerator is more complicated than a direct-cooled refrigerator, so the product manufacturing cost is higher and more expensive. In addition to the fan rotation, the noise is also louder than that of a direct-cooled refrigerator.
