As a chest freezer factory with many years of freezer production experience, I will tell you the difference between direct-cooling refrigerators and air-cooling refrigerators.
The air-cooled refrigerator is frost-free, clean, and refreshing. The air-cooled refrigerator will not be always wet inside like the direct-cooled refrigerator, and the food will not stick to each other. Moreover, the air-cooled refrigerator will have continuously circulating cold air, and then filtered by the deodorization system, the internal smell will be maintained for a long time.
Accurate temperature and more uniform cooling. Air-cooled refrigerators have more precise temperature control than direct-cooled refrigerators because direct-cooled refrigerators are prone to cooling dead spots. After all, the evaporator is attached to the box, so the temperature of the temperature control point test is the same as the temperature inside the refrigerator. Compared with the overall actual temperature, there may be differences, which will affect the freshness quality of food.
The food stored in the air-cooled refrigerator is easy to dry out and lacks water. There will be a continuous circulation of cold air inside the refrigerator, which will lower the air humidity in the refrigerator. Dry, the price is more expensive, the noise is slightly louder, and the internal structure of the air-cooled refrigerator is more complicated than that of the direct-cooled refrigerator, so the manufacturing cost of the product is higher and more expensive.
Direct cooling refrigerators have a better fresh-keeping effect, allowing us to enjoy more fresh food, low power consumption, and low prices. Direct-cooling refrigerators are usually used for economical products with two doors. The direct cooling structure is that the evaporator is directly exposed to In the cabinet, the cost will be lower and the noise will be relatively small.
