Refrigerators are what people use to store food. With the development of science and technology, refrigerators are constantly being developed and updated. The old-fashioned refrigerators in the past have gradually developed into direct cooling refrigerators and air-cooled refrigerators. Now the frost-free refrigerators we often say refer to what we are talking about here. The air-cooled refrigerator arrived, so, is the air-cooled frost-free refrigerator good? Air-cooled refrigerators use the method of lowering the temperature to lower the temperature of the refrigerator. It is also called a frost-free refrigerator. The fan blows air into the condenser to produce frost like cold and cold. The inside of the box is clean and tidy, the air inside is fresh, and the food will not stick together. In addition, the air-cooled refrigerator technology can control the temperature very well, and all the spaces in the box can maintain a uniform temperature.
The advantage of the air-cooled kitchen reach in refrigerator is that it is frost-free. The air-cooled refrigerator will not always be wet inside like a direct-cooled refrigerator, and the food will not stick to each other unclearly. In addition, the air-cooled refrigerator will have continuous circulation of cold air, and then filtered by the deodorizing system, the internal smell will remain fresh for a long time. There will be no more pungent odors. In addition, because the air-cooled refrigerator can automatically defrost, it can be said to reduce the burden of manual defrosting. After all, defrosting the refrigerator is a hard work. Friends who have experienced it must resonate. The air-cooled refrigerator solves this well. problem.
In fact, air-cooled refrigerators are not frost-free, but frost condenses on the top of the evaporator. Because it is inside the refrigerator, we cannot see it directly when we open the refrigerator door, so it is vividly called frost-free. For this part of frost, The current mainstream technology is to remove heat through heat evaporation, that is, when the refrigerator works-after a period of time, the refrigerator stops cooling, starts the defrost heating system, the condensed frost will become water after being heated, and then discharged through the duct. This work is the refrigerator. It is done automatically and does not need to be processed manually by the user.
What is the difference between an air-cooled refrigerator and a direct-cooled refrigerator?
Comparison of cooling effect and power consumption
The air-cooled refrigerator has more air supply from the fan, so the indoor temperature of the refrigerator is relatively average, there is no big temperature change, and the cooling effect is naturally better. Therefore, the air-cooled refrigerator has a more uniform temperature. For direct cooling, the cooling speed is slower, because the air is not convective and the temperature is uneven, and there will be a "refrigerator smell". However, since the direct cooling type does not have an electric fan, it will not generate additional noise and power consumption, and will not cause drying on the surface of the food due to blowing.
The total power consumption of direct-cooling refrigerators is much lower, and the refrigeration is relatively slow. The problem is that they need to be defrosted regularly. Maybe the electricity we save is given to the frozen refrigerator. From a long-term point of view, air-cooled refrigerators are much better than direct-cooled refrigerators. We only need to pay attention to keeping food spacing, which saves electricity costs and does not require us to take care of them regularly. So overall, air-cooled refrigerators are better.
