Which is better, direct-cooling refrigerator or air-cooling refrigerator? What are their advantages and disadvantages?

Refrigerator plays a very important role in our daily life. Look at our usual food, how can it exist without it, but the only worry about using the refrigerator is defrosting, but only now most refrigerators are equipped with automatic defrosting function, and the effect is also very good, then how about the automatic defrosting effect of the direct cooling refrigerator? This may be a matter of great concern to all of us, so let's introduce which is better, the direct-cooling refrigerator or the air-cooling refrigerator. What are their characteristics?

Which is better, direct-cooling refrigerator or air-cooling refrigerator?

1, direct-cooling refrigerator is cheap and durable.

There are five types of refrigerators in the market: single door, double door, opposite door, three door and multiple door. Among them, air cooling is mainly used for refrigerators with two doors and a capacity of more than 200L, which is expensive, basically higher than 1800 yuan, and the expensive one is more than 20,000 yuan; The direct cooling technology has a wider range of applications, ranging from single-door to multi-door products, which are not as cheap as those in 500 yuan.

2, direct cooling refrigerator moisture is not easy to lose.

The direct-cooling refrigerator is designed to directly connect the cooling pipe of the evaporator of the refrigerator to the inside or the back of the refrigerating chamber and the freezing chamber. When the evaporator absorbs heat, the air closer to the cooling pipe cools faster, thus forming natural convection in the refrigeration room, reducing the temperature of food and reducing the loss of food moisture.

3, air-cooled automatic defrosting ability is large.

In fact, air-cooled refrigerators do not produce frosting, and basically let the frost condense on the evaporator instead of the inner wall of the refrigerator. In the current mainstream products, the evaporator of air-cooled refrigerator is arranged inside the refrigerator and separated from the inner wall of the refrigerator. Therefore, the inner wall of the refrigerator will not frost, so it is called frost-free. After working for a period of time, the refrigeration is suspended, and the refrigerator will start the defrosting heating system to evaporate the frost condensed on the evaporator. The condensed frost will turn into water when heated, and then it will be discharged through a special conduit (or directly evaporated into steam). This work is done automatically in the refrigerator without manual defrosting.

4. The air cooling temperature is even and there is no peculiar smell.

At the beginning of the design of air-cooled refrigerator, the evaporator must be separated from the food, and the fan must force the cold air to circulate. Therefore, when storing food, the temperature in the refrigerator is relatively uniform, and there will be no humidity in the refrigerator like a direct-cooling refrigerator, and there will be no freezing of two foods together, and there will be no excessive freezing caused by food sticking to the inner wall, so that the sense of food will not be affected.

Advantages and disadvantages of direct cooling refrigerator

1, and air conditioners are divided into constant speed and frequency conversion, and refrigerators are also divided into direct cooling and air cooling. However, when consumers buy, they may be more concerned about intuitive factors such as price, capacity and appearance, and less concerned about the specific refrigeration mode inside the refrigerator.

2. The direct-cooling refrigerator is designed to directly connect the cooling pipe of the evaporator of the refrigerator to the inside or the back of the refrigerating chamber and the freezing chamber. When the evaporator absorbs heat, the air closer to the cooling pipe cools down faster, thus forming natural convection in the refrigeration room, reducing the temperature of food and reducing the loss of food moisture.

3. The advantages of direct cooling refrigerator are simple structure and low failure rate. In addition, the enclosed space of this refrigerator naturally convects, the air humidity is high, the moisture of food is not easy to lose, and it also saves electricity. The disadvantage is that manual defrosting is often needed.

Advantages and disadvantages of air-cooled refrigerator

1, air-cooled refrigerator is the cold air generated by the built-in hidden evaporator, which is forced to circulate by the fan, so that the cold air is evenly distributed in all rooms of the refrigerator to realize refrigeration. Because of the existence of the fan, air cooling 2. The refrigerator cools faster.

The biggest advantage of air-cooled refrigerator is that it can defrost automatically. Save worry and effort. In fact, air-cooled refrigerators do not produce frosting, and basically let the frost condense on the evaporator instead of the inner wall of the refrigerator. Therefore, the inner wall of the refrigerator will not frost, so it is called frost-free. At the same time, the temperature uniformity of food preservation is good, the humidity is small, the food is dry and the smell is fresh. The disadvantage is that it consumes more electricity than the direct-cooling refrigerator.

What we introduced above is about the direct-cooling refrigerator or the air-cooling refrigerator, which is better? What are their characteristics? We should know something about these problems. We know that direct-cooling refrigerators can't defrost automatically, so we usually do it ourselves. Friends who are in trouble can choose to buy air-cooled refrigerators, which is more energy-saving. It is also good for economical friends to choose a direct-cooling refrigerator, which is also easier to store food.
