The biggest advantage of an air-cooled refrigerator is that it is frost-free. An air-cooled refrigerator won't always be wet on the inside like a refrigerated refrigerator, and the food won't stick to each other. Moreover, the air-cooled refrigerator will have a continuous circulation of cold air, and then through the filtration of the deodorization system, the internal odor will also remain fresh for a long time, and there will no longer be that pungent "refrigerator smell".

Also, because the air-cooled refrigerator can be automatically defrosted.

In 2013, Yikang did a market survey on the household appliance industry, when the air-cooled refrigeratorMarket shareIt has already reached an increase over 2012, when it was predicted that air cooling would gradually become mainstream. Sure enough, in the next three years, consumers' attention to air-cooled refrigerators has skyrocketed, after all, there are many more advantages than direct-cooling refrigerators.

Frost-free refrigerators are popular, generally frost-free refrigerators are refrigerators with air-cooled design, the principle of air-cooled refrigerators is to use air for refrigeration, and high-temperature air flows through the built-in evaporator.

separated from the inner wall of the refrigerator), the air temperature is low due to the high air temperature and the low temperature of the evaporator, and the heat exchange between the two directly occurs, and the temperature of the air decreases. At the same time, the cold air is blown into the refrigerator. Air-cooled refrigerators are used in this continuous cycle to reduce the temperature of the refrigerator.

When many consumers buy refrigerators, they will be asked by the shopping guide whether they want to be air-cooled or directly cooled, and many friends who buy refrigerators for the first time will be asked confused, so what isAir-cooled refrigerator

Air-cooled refrigerators are welcomed, generally frost-free refrigerators are refrigerators with air-cooled design, the principle of air-cooled refrigerators is to use air for refrigeration, when high-temperature air flows through the built-in evaporator (separated from the inner wall of the refrigerator), due to the high air temperature and low evaporator temperature, the heat exchange between the two directly occurs, the temperature of the air will be reduced, and the cold air will be blown into the refrigerator at the same time. The air-cooled refrigerator is to reduce the temperature of the refrigerator through this continuous circulation.

What are the advantages and disadvantages of air-cooled refrigerators?

Advantages of air-cooled refrigerators:

1. Frost-free, clean, refreshing and worry-free. The biggest advantage of air-cooled refrigerators is that there is no frost, air-cooled refrigerators will have continuous circulation of cold air, and then after the filtration of the deodorization system, the internal odor will remain fresh for a long time, and there will be no more that pungent "refrigerator smell". In addition, because the air-cooled refrigerator can automatically carry the orange with defrost, it can be said that it greatly reduces the burden of manual defrosting for users.

2. Accurate temperature refrigeration is more uniform. Air-cooled refrigerators have more precise temperature control than direct-cooled refrigerators. Because the direct cooling refrigerator is prone to refrigeration dead ends, after all, the evaporator is attached to the box, so the temperature of the temperature control point test may be a few degrees different from the actual temperature inside the refrigerator, which will affect the preservation quality of food.

The air-cooled refrigerator is relatively more stable and uniform because the cold air is evenly circulated, so the internal stability is relatively more stable and uniform, so it will reach the temperature required by the user more accurately, which will make the food preservation effect better and the freshness time longer to a large extent.

Disadvantages of air-cooled refrigerators:

1. Food is easy to dry and lack of water. Because the air-cooled refrigerator will have a continuous circulation of cold air, which will make the air humidity in the refrigerator low, some foods are easy to lack water if they are not isolated with plastic wrap or crisper boxes, and then be blown dry. Therefore, many air-cooled refrigerators are currently designed with some smaller storage boxes, which are not only convenient for food to be stored in the open air, but also to slow down the air-drying speed of food.

2. **Slightly louder than expensive. The internal structure of air-cooled refrigerators is more complex than that of direct-cooled refrigerators, so the manufacturing cost of the product is higher, so air-cooled refrigerators of the same volume and brand are generally more expensive than direct-cooling refrigerators, which may make some users choose direct-cooling refrigerators. In addition, air-cooled refrigerators require fans to constantly blow cold air into all corners of the refrigerator, so relatively speaking, the noise will be a little louder than that of direct-cooled refrigerators.

That's all for you: What is an air-cooled refrigerator? What are the advantages and disadvantages of air-cooled refrigerators? All of it.

1. Which brand of air-cooled refrigerator is better?

1. Haier. Founded in 1984, it has been more than 30 years, after 30 years of continuous polishing, its products are more and more mature, new, it is the preferred brand in the small family, whether it is the style or sex can be very good, the space occupied is also very small, relatively affordable, the storage space is very large.

2. Whirlpool.

Founded in 1911, it has a history of more than 100 years, as one of the world's largest manufacturers of household appliances, it can be said to be a veteran brand in the refrigerator industry, its influence is very large abroad, has always been the overlord of the refrigerator industry.

3. Electrolux.

Founded in 1919, it's been almost a hundred years since then, and everything they produce is based on them.

Mute. Mainly, its biggest advantage is that it has very versatile performance and outstanding appearance, it can be said that it is the world's largest manufacturer of kitchen equipment, cleaning and washing equipment and outdoor appliances, ** compared to refrigerators are slightly expensive.

Second, the advantages of air-cooled refrigerators.

Air-cooled refrigerator is the use of air to make cold air, if the temperature of the air is relatively high, then the temperature emitted by the evaporator will be relatively low, a heat alternation occurs between the two, so that the temperature of the group elimination space gradually decreases, while the cold air blows into the refrigerator, so that the temperature in the refrigerator is reduced, and the air-cooled refrigerator is more suitable for use in areas with humid weather such as the south. The refrigeration speed of the air-cooled refrigerator is very fast, the distribution is also very uniform, the temperature control is accurate, and because the humidity in the box is relatively small, the food will not stick to the refrigerator, and the phenomenon of cross-smell will appear, and its capacity is very large.

In 1879, the German engineer Carl von Lind built the first household refrigerator.

The world's first refrigerator was born in 1918 and was designed and manufactured by E.J. Coberland, an engineer from Carl Wienert in the United States.

Another theory is that in 1834, the American engineer Jacob 6 1 Perkins invented the world's first compression refrigeration device, which is the prototype of the modern compression refrigeration system. In the same year, Perkins received the first patent for a freezer in the United Kingdom.

Nowadays, there are more and more types of household appliances, and all kinds of electrical equipment products are placed in front of us, among which refrigerators are a very common one, so is it good to have air-cooled refrigerators? What are the advantages and disadvantages of air-cooled refrigerators? Let's introduce you to the basic knowledge of air-cooled refrigerators.

This kind of refrigerator is one of the more advanced technology at present, its advantage is mainly that it will not have frost when it is used, but the air conditioning is kept very even, and the internal deodorization function is also available, so it will not produce peculiar smell, and the food can be kept very fresh, mainly because it can achieve automatic defrosting.

Advantages and disadvantages of air-cooled refrigerators.

Advantages: 1. It adopts a new frost-free technology, which does not produce frost, and is very clean and fresh inside. Its refrigeration mode is circulating cold air refrigeration, and the internal odor removal function also has the function of deodorization, so it will not produce peculiar smell, and the food can be kept very fresh, 2. Accurately regulate the internal temperature, control the internal temperature is very average, basically the internal temperature is consistent, there is no dead end, so the temperature distribution in the air-cooled refrigerator is very uniform.

Disadvantages: 1. Because it is a circulation to transport cold air, and it will not produce frost, there may be a shortage of water after a long time of food preservation. The circulating cold air makes the temperature lower, and the moisture will become less and less, and it is easy to suffer from water shortage.

2. Compared with the general refrigerator, it will be higher than the front of the refrigerator, it is better in terms of design and performance, and the structure is more complex, and the cost is naturally higher.

3. Because it is circulating to transport cold air, the smell will also flow with it, resulting in the phenomenon of food cross-smelling, although many air-cooled refrigerators are layered in order to solve this problem, but this also increases the cost and volume of the refrigerator.

<> "In order to meet people's needs, there are many kinds of refrigerators with various functions on the market, and before you choose them, you must understand its advantages and disadvantages.

What are the advantages and disadvantages of air-cooled refrigerators.

Advantages: 1. Clean, refreshing and effortless.

On the other hand, it has a continuous circulation of cold air for direct cooling, and can also be filtered by the deodorization system to ensure that the smell in the refrigerator is fresh and odorless, and there will be no refrigerator smell.

2. The temperature is accurate and the refrigeration is uniform.

The temperature control is more accurate, because the refrigeration method of the direct cooling refrigerator is easy to make the direct cooling uneven, and the air-cooled refrigerator can be floated to any corner, so the refrigeration effect is better.

Disadvantages: 1. High noise is high.

On the other hand, the air-cooled refrigeration structure is a little more complex, and the noise is also large when the temperature is controlled.

2. Food is easy to dry and lack of water.

The air cooling effect tends to make the air humidity in the refrigerator low, resulting in the moisture on the surface of the food being easily dried out and lacking water.

How to choose a refrigerator.

1. Function. There are more and more functions of the new refrigerator, and when choosing, we should pay attention to whether its functions are practical, like ordinary family needs are limited to the most basic functions of freshness, and do not need to spend too much money, while refrigerators with complex designs will be expensive.

2. Materials. When buying a refrigerator, it is easy for people to ignore the insulation layer of the refrigerator, which directly affects the quality of freezing and preservation.

3. Refrigeration method.

The old refrigerator cooling method is usually direct cooling, and air cooling is a new main type, most high-end refrigerators are using this air cooling, on the one hand, the volume of the air cooler will be larger, and there is a better nutritional preservation effect of Hengchong on food.
