Analysis on the difference between direct cooling and air cooling of refrigerator

It is estimated that most families have bought refrigerators now! Refrigerator occupies a very high position in many household appliances, mainly because of its practicality. Because the product is highly practical, people will naturally buy it. Many people buy refrigerators at will. In fact, this way is wrong, because there are many differences between refrigerators, such as refrigerators have mass and weight. So do you know the difference between intelligence and refrigerator intelligence?

Difference between direct cooling and air cooling 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.

Fourth, air cooling because there is no electric fan, it will not produce additional noise and power consumption, and at the same time, it will not dry the food surface due to blowing.

5. Because air cooling is the forced circulation of cold air, it has the advantages of fast cooling speed and good temperature balance, which is incomparable to direct cooling. However, direct cooling depends on natural convection, so the temperature balance is poor and the cooling speed is low.

Six, the inherent defrosting cycle of air cooling, fans and multiple internal compensation heaters lead to higher power consumption and noise than direct cooling refrigerators, so air cooling certainly has no advantage in these two aspects under similar circumstances. Look at the national and international refrigerator performance and energy consumption grade standards, and you will understand this. Therefore, boasting that air cooling has lower energy consumption and less noise than direct cooling is incomparable under the same conditions.

Seven, direct cold manual defrosting is really annoying. The so-called micro-frost design is to freeze all drawers and reduce the air flow in the door-opening box to reduce frosting. Even so, it usually needs to be thawed for half a year. If the number of doors is small, it can be extended, otherwise it will be shortened. If the door seal is not good or aging, frosting will also become serious. With the extension of service time, the number of defrosting will increase.

Eight, air cooling Due to the forced circulation of air, the smell will move in all rooms. Now there are also some air-cooled refrigerators with dual systems, and it is better to separate refrigeration from refrigeration.

Nine, the air-cooled refrigerator constantly brings the moisture in the box to the evaporator, and it flows away when defrosting, which brings dry consumption in the box and is not conducive to preservation. This is also an inherent disadvantage of air cooling. Although there are some so-called preservation technologies, they are only in a small area (such as a relatively sealed space), and cold air is not allowed to enter, but only flows around. In fact, space is close to natural convection, but it is directly cooled in a small space.

Bian Xiao has given you a detailed introduction to the difference between direct cooling and air cooling in the refrigerator. I believe that after reading Bian Xiao's introduction, everyone should understand the specific difference between direct cooling and air cooling in refrigerators! Of course, Bian Xiao's summary of refrigerator direct cooling and air cooling may not be comprehensive, but we should know it in detail. No matter what products are made from generation to generation, I believe that with the continuous progress of technology, better refrigerator products will be born in the future.
