There are two cooling methods in mainstream refrigerators: direct cooling and air cooling. In fact, many people do not understand which one is better. In today's article, we will analyze the advantages and disadvantages of air cooling and direct cooling.

Which is better, direct cooling or air cooling? It depends on the budget!

Air-cooled refrigerators have been widely used in offline stores, while traditional direct-cooled refrigerators are only available online or in local appliance stores. To make way for air-cooled refrigerators, the price of direct-cooled refrigerators is also "cut in half."

Therefore, if the budget is limited to less than 1,000 yuan, air-cooled refrigerators are still the first choice. Secondly, if you want to buy a large-capacity refrigerator of more than 400L, an air-cooled refrigerator is recommended. After all, defrosting is a big project.

Besides being cheap, what are the advantages and disadvantages of direct cooling refrigerators?

Advantages: Direct cooling refrigerators consume relatively low power, and the evaporator is directly exposed on the cabinet, so the cost is lower and the noise is relatively low.

Disadvantages: The cooling speed of direct cooling refrigerators is relatively slow, which makes people feel that it is inconvenient to use, and the evaporator is prone to collision. Scrape. Corrosion, causing leakage and affecting life. Its biggest disadvantage is that it must be manually defrosted several times a year. Generally, the volume of a direct cooling refrigerator is below 300L.

What are the advantages and disadvantages of an air-cooled non-frost refrigerator except that it does not need to be defrosted regularly?

Advantages: The air-cooled refrigerator will have continuous circulation of cold air, and then filtered by the deodorizing system, the internal smell will remain fresh for a long time. In addition, air-cooled refrigerators have more precise temperature control than direct-cooled refrigerators.

Because direct cooling refrigerators are prone to dead spots, after all, the evaporator is attached to the box, so the temperature tested by the temperature control point may be different from the actual temperature inside the refrigerator, which will affect the quality of food preservation.

Disadvantages: Because there will be continuous circulation of cold air inside the air-cooled refrigerator, the air humidity in the refrigerator will be lowered. If some foods are not isolated with plastic wrap or fresh-keeping boxes, they are prone to lack of water and be blown dry.

The internal structure of an air-cooled refrigerator is more complicated than that of a direct-cooled refrigerator, so the manufacturing cost of the product is higher and more expensive. Coupled with the reason that the fan rotates, the noise is larger than that of a direct cooling refrigerator.

Purchase advice: If you buy a large-capacity refrigerator, it is recommended to choose an air-cooled refrigerator. Although the price is slightly more expensive, the freshness and direct cooling effect are better. If you are using it in a rental room, a direct cooling refrigerator is still a good choice. Although the freshness is slightly poor, the fruits and vegetables can be stored for 1 to 2 days.
