1. Direct cooling refrigerator
Advantages: The internal refrigeration system of the direct cooling refrigerator is relatively simple, the product price is affordable, the later maintenance is low, it is convenient for people to use, and the market penetration rate is also high.
Disadvantages: When the direct cooling refrigerator is working, the inside of the refrigerator cannot be evenly cooled, which will cause the inside of the refrigerator to form frost, which requires manual cleaning.
2. Air-cooled refrigerator
Advantages: The cooling effect of air-cooled refrigerators is better than that of direct-cooled refrigerators. In addition, it can keep the refrigerator evenly cold, so it is not easy to form a thick layer of frost, which saves a lot of manpower.
Disadvantages: The system structure of air-cooled refrigerators is more complicated, so the cost of the product is higher than that of direct-cooled refrigerators, the product price is also high, and the later maintenance costs are also higher. In addition, because the working principle of the air-cooled refrigerator is air-drying, the air humidity is low, and the food preservation effect is poor.
3. Mixed cold refrigerator
Advantages: Air-cooled refrigerators combine the advantages and disadvantages of direct-cooled refrigerators and air-cooled refrigerators, so the performance of the product is more complete, regardless of the refrigerator's refrigeration efficiency and freshness preservation ability.
Disadvantages: The cost of mixed-cooling refrigerators is relatively high and expensive. The technology of mixed-cooling refrigerators is not yet mature, and the market popularity is not high.
