In daily life, refrigerators have become one of the indispensable household appliances in the family.
However, when buying a refrigerator, consumers often encounter such a question: which is more suitable for themselves, direct cooling or air cooling?This article will give you a detailed analysis of the differences between direct cooling and air cooling of refrigerators, as well as their respective advantages and disadvantages.
1. The difference between direct-cooled and air-cooled refrigerators
1.The principle of refrigeration is different.
Direct-cooled refrigerators: Direct-cooled refrigerators use natural convection to refrigerate, and cold air is dissipated directly from the evaporator to the inside of the refrigerator.
The refrigerant evaporates in the evaporator and absorbs heat, causing the temperature inside the refrigerator to decrease.
Air-cooled refrigerators: Air-cooled refrigerators use forced convection to cool the refrigerator, blowing cold air into the refrigerator through a fan.
The refrigerant evaporates in the evaporator to absorb heat, and the cold air is blown into the refrigerator through a fan, so that the temperature in the refrigerator is reduced.
2.Structural differences.
Direct-cooled refrigerator: The internal structure is relatively simple, no fan is required, so the space utilization rate is high.
Air-cooled refrigerators: The internal structure is relatively complex, and fans need to be installed, and the space utilization rate is relatively low.
2. Analysis of the advantages and disadvantages of direct-cooled and air-cooled refrigerators
1.Advantages and disadvantages of direct-cooled refrigerators.
Pros: aThe structure is simple, the failure rate is low, and the maintenance is convenient
b.The refrigeration speed is fast and the effect is good;
c.Good energy-saving performance and low power consumption;
d.*Relatively low.
Cons: aThe internal humidity is high, which is easy to frost, which affects the preservation of food;
b.Refrigerants can cause contamination in direct contact with food;
c.The temperature distribution is uneven, with lower temperatures near the evaporator and higher temperatures far away.
2.Advantages and disadvantages of air-cooled refrigerators.
Pros: aThe internal humidity is low, which avoids frost problems and has a good food preservation effect
b.Uniform temperature distribution avoids humidity fluctuations caused by temperature gradients
c.The fan can effectively remove odors and keep the air in the refrigerator fresh
d.The sleek look is suitable for a modern home environment.
Cons: aThe structure is complex, the failure rate is relatively high, and the maintenance cost is high
b.Relatively high power consumption;
c.*Relatively expensive.
To sum up, direct-cooled and air-cooled refrigerators have their own advantages and disadvantages, and consumers can choose according to their needs and budget when purchasing.
For consumers who pursue cost-effective and energy-saving performance, direct-cooled refrigerators are a good choiceFor consumers who pay attention to the internal humidity control and appearance design of the refrigerator, air-cooled refrigerators can better meet the demand.
