The importance of a refrigerator for a family is self-evident. Now we go to buy a refrigerator, no longer like before, choose a good style, as long as it is with a frozen preservation function. Nowadays, with the improvement of modern people's living standards, people pay more and more attention to the preservation of ingredients and nutrition processes, and some refrigerators are also equipped with "intelligent" systems to make refrigerators more advanced, but at the same time, consumers are picky.
In fact, since the Americans invented the world's first refrigerator in 1918, the direct cold refrigerator has always been the protagonist in the market, and with the advancement of science and technology, in the past ten years, the refrigeration method has made new breakthroughs, there have been air-cooled refrigerators, and of course, there are better mixed refrigerators. Today, we will talk about the direct-cooled refrigerator and air-cooled refrigerator that everyone often struggles with, who is more worth choosing.
First of all, let's talk about the advantages and disadvantages of direct cold refrigerators. In the past, old-fashioned refrigerators were all direct cold refrigerators, for those who have not used air-cooled refrigerators, direct refrigerators seem to be a big problem, a refrigerator can be used for 7-8 years or even longer, but the most annoying is the problem of frost. Over time, the refrigerator will frost, resulting in an increase in refrigerator power consumption, on the other hand, it is easy to breed bacteria and affect the freshness of food. So every time you use it, you will find that the frozen drawer wants to pull out of no way, can only cut off the power for one night, and then re-connect the power to use when the frost melts, which is particularly troublesome.
In addition to the most criticized shortcomings of frost, there are also some shortcomings of the direct cold refrigerator, such as: poor temperature control, cooling speed is relatively slow, of course, if these are not used in the air-cooled refrigerator comparison, this point many people do not care much. However, the cold volume of the direct cold refrigerator will be unevenly distributed, because its refrigeration method will make the refrigerator have a freezing dead end, so some food close to the inner wall of the refrigerator will often be frozen, and it is precisely because of these shortcomings that the direct cold refrigerator is slowly eliminated by the market.
At present, the direct cold refrigerator may account for about 10% of the total sales of the market, but it is better than the price, if it is used in a rental house, it is still quite appropriate, plus it is simple in structure, so the failure rate is low, basically used for 10 years is still very strong.
Then we talk about the air-cooled refrigerator, compared to the direct-cooled refrigerator, the advantages of the air-cooled refrigerator will be more, and obviously the price will be higher. The most satisfactory thing is that the use of air-cooled refrigerators does not need to be manually defrosted, and the cold air of the refrigerator is blown into the refrigerator through the fan, and the air conditioning circulates and flows, evenly distributed in the refrigerator to achieve refrigeration, so the refrigerator temperature is more uniform, and there will be no such thing as freezing food.
In addition, the temperature control of the air-cooled refrigerator is more accurate. Don't underestimate this, like we southerners can't do without a variety of fruits all year round, the temperature-controlled refrigerator can make the fruits and vegetables keep fresh and moist, and extend the food preservation time.
However, the air-cooled refrigerator also has certain disadvantages, such as easy string taste, because the air-cooled refrigerator is designed with the air duct of the freezer room and the cold room, and when refrigerating, the cold air blows out of the air duct, so that the taste of the food will drift away, resulting in the string taste. In addition, the moisturizing properties will be poor, because the wind is blowing all the time, and some green leafy vegetables or fruits with high water content will lose water quickly.
Still, according to current market trends, air-cooled refrigerators are still better than straight-cooled refrigerators. When we choose, if we choose an air-cooled refrigerator with two independent circulation systems (multi-cycle), it can effectively reduce the problem of food skewers, in addition, the frequency conversion technology can more reasonably adjust the output power of the compressor and the speed of the fan, so that the problem of high energy consumption of the air-cooled refrigerator can also be improved, and the noise generated by the refrigerator can be reduced.
In fact, each kind of refrigeration method of the refrigerator, has its advantages and disadvantages, everyone chooses the most suitable for their own when shopping, is the right choice. Do you use an air-cooled refrigerator or a direct-cooled refrigerator in your home? Let's talk about the sense of experience!
