Introduction: As an essential product of China's home appliances, refrigerators have entered thousands of households.
However, when choosing a refrigerator, many consumers have difficulty choosing between air cooling and direct cooling.
This article will explain the difference between air-cooled and direct-cooled refrigerators in detail for you, and help you find the most suitable refrigerator for your life needs.
1. Definition and principle of air-cooled refrigerator and direct-cooled refrigerator
1. Air-cooled refrigerator:
Air-cooled refrigerators use air cooling technology to blow cold air into the refrigerator through a fan to achieve refrigeration.
Air-cooled refrigerators have finned evaporators inside that blow cold air into the refrigerator through a fan to keep food fresh.
2. Direct cooling refrigerator:
Direct cooling refrigerators use direct evaporative refrigeration technology, in which the refrigerant is directly exchanged with the heat inside the refrigerator to achieve refrigeration.
The evaporator of the direct-cooling refrigerator is directly attached to the inner wall of the refrigerator, and the heat is absorbed through the evaporation of the refrigerant, so that the internal temperature of the refrigerator is reduced.
2. The difference between air-cooled refrigerators and direct-cooled refrigerators
1. Refrigeration effect:
The cooling effect of an air-cooled refrigerator is more stable because it uses air cooling technology, which can make the internal temperature of the refrigerator more uniform.
The refrigeration effect of a direct cooling refrigerator is affected by the internal space of the refrigerator and the area of the evaporator, and the temperature may be uneven in some parts.
2. Defrosting effect:
Air-cooled refrigerators use finned evaporators, which are prone to accumulation of frost layers and need to be defrosted regularly.
The evaporator of the direct-cooling refrigerator is directly attached to the inner wall of the refrigerator, and the frost layer is not easy to form, so the number of defrosting is relatively small.
3. Noise and energy saving
Air-cooled refrigerators produce a certain amount of noise when running due to the built-in fan.
Whereas, direct-cooling refrigerators do not require a fan and operate quietly.
In addition, the energy consumption of air-cooled refrigerators is relatively high because the fan is required to consume electricity.
4. ** and maintenance:
Air-cooled refrigerators are generally higher than direct-cooled refrigerators, but due to the relatively complex structure of air-cooled refrigerators, the maintenance cost is also higher.
The structure of a direct-cooling refrigerator is relatively simple and the maintenance cost is low.
5. Applicable people:
Air-cooled refrigerators are suitable for people who are sensitive to temperature fluctuations, such as storing items such as breast milk and medicines that require strict temperature control.
Direct cooling refrigerators, on the other hand, are more suitable for people who are sensitive to noise and pay attention to energy saving.
3. Purchase suggestions
When choosing a refrigerator, consumers should choose according to their living needs and budget.
If you have high requirements for the cooling effect and temperature stability of the refrigerator, you can choose an air-cooled refrigerator.
If you are energy-efficient, quiet, and do not require high refrigeration efficiency, you can choose a direct-cooling refrigerator.
Summary: Air-cooled refrigerators and direct-cooled refrigerators have their own advantages and disadvantages, and consumers should choose according to their needs and budget when purchasing.
By understanding the difference between the two, I believe you have found the type of refrigerator that suits you.
In the future purchase process, I wish you to buy a satisfactory refrigerator and bring more convenience and comfort to family life!
