Freezers are one of the indispensable electrical appliances in our modern supermarkets. The continuous advancement of technology, various functions, and various styles of freezers emerge in an endless stream. Supermarket shops wait for the selection of freezers. I don’t know what to choose. Now on the market. The above-mentioned freezers are roughly divided into two types, direct cooling freezers and air-cooled freezers. So when we buy freezers, which one should we choose is better? Let us discuss this issue next.
Air-cooled freezer
First, the advantages:
1. Frost-free, clean, refreshing and worry-free.
The air-cooled refrigerator will not always be wet inside like the direct-cooled refrigerator, and the food will not stick to each other unclearly. Moreover, the air-cooled refrigerator will have continuous circulation of cold air, and then filtered by the deodorizing system, the internal smell will be maintained for a long time.
2. The temperature is precise and the cooling is more uniform.
The air-cooled refrigerator has a fast cooling speed, and the air-conditioning is evenly distributed.
Second, the disadvantages:
1. Relative to direct cooling, the air humidity inside the air-cooled refrigerator is low. If some food is not isolated with plastic wrap or fresh-keeping box, it may be dry without water.
2. The internal structure of an air-heated refrigerator is more complicated than that of a direct-cooled refrigerator, so its manufacturing cost is higher and the price is more expensive.
Direct cooling freezer
First, the advantages:
1. Good fresh-keeping effect.
Direct-cooling refrigerators are also called frost refrigerators, which have excellent fresh-keeping effects and allow us to enjoy more fresh-keeping foods.
2. Low power consumption and low price.
The structure of the direct cooling refrigerator is that the evaporator is directly exposed in the cabinet, and the cost will be lower, so the price is naturally not expensive.
Second, the disadvantages:
1. The cooling speed is slow.
The cooling speed of direct cooling refrigerators is relatively slow, which makes people feel inconvenient to use.
2. Direct cooling refrigerators must be manually defrosted several times each year, which is relatively troublesome.
The working principle of direct cooling freezer and air cooling freezer
1. Direct cooling freezer: We will find that the refrigeration pipes can be directly seen in the direct cooling freezer, so the direct cooling freezer reduces the temperature inside the refrigerator through such a cold and heat exchange. However, when the cold air in the freezer comes into contact with the refrigerating pipes, frost will form.
2. Air-cooled freezer: Both air-cooled freezers and direct-cooled freezers are cooled by the evaporator, but the evaporator of the air-cooled freezer is not in direct contact with the inside of the freezer, and the main cooling method is also by blowing cold air. Yes, in the working state, frost will also occur, but it is not inside the freezer, but on the top of the evaporator. Therefore, the air-cooled freezer will defrost through the drain pipe or evaporate the frost into water vapor.
Which is better, direct cooling or air cooling?
1. Whether to defrost
With a refrigerator, deicing is a headache. Direct-cooled refrigerators will produce frost, while air-cooled refrigerators have no frost inside. Therefore, air-cooled refrigerators do not need to be manually defrosted, while direct-cooled refrigerators need to be defrosted.
2. Food preservation effect
The direct-cooling refrigerator cools down by heat exchange, and the cooling speed is fast, and the food enters the fresh-keeping state faster; while the air-cooled refrigerator cools the temperature by blowing cold air. In the state of blowing, the food is easy to lose water and reduce the temperature. The freshness of the food. Therefore, the direct cooling refrigerator is better in terms of preservation effect.
3. Refrigeration temperature
Air-cooled refrigerators have certain advantages in this respect. Because air-cooled refrigerators blow cold air, the temperature in the refrigerator is more uniform, while there will be a certain temperature difference in various places of direct-cooled refrigerators.
4. Failure rate
Obviously, the direct cooling freezer has certain advantages. The direct cooling freezer is a more traditional refrigerator, so the refrigeration process is relatively mature, and the structure is simple, so the failure rate is also low.
The above is the specific content about the choice of direct cooling or air cooling for supermarket refrigerators. In fact, the two types of refrigerators are not the most perfect. They both have shortcomings. However, in comparison, direct cooling refrigerators have more advantages. You can refer to the supermarket or store. According to the actual situation and demand, if there are not many things in the freezer in a small supermarket or store, it is still better to buy a direct cooling freezer.
