Is it better for the refrigerator to be air-cooled or directly cooled?This problem plagues many consumers, especially when it comes to buying a refrigerator.
In order to help you better understand these two refrigeration methods, this article will conduct a detailed analysis from the principles, advantages and disadvantages to answer this question for you.
1. Introduction to the principle of refrigerator refrigeration
Whether air-cooled or direct-cooled, they work by circulating the refrigerant through components such as compressors, condensers, expansion valves, etc., to achieve the process of absorbing and releasing heat.
In this process, the refrigerant evaporates in the evaporator (inside the refrigerator) to absorb heat, causing the temperature inside the refrigerator to decrease.
2. The difference between air-cooled refrigerators and direct-cooled refrigerators
1.Air-cooled refrigerator.
Air-cooled refrigerators use a fan to blow cold air into the inside of the refrigerator to keep food cold.
The inside of an air-cooled refrigerator has an air duct that blows the refrigerant to all corners through a fan to achieve uniform cooling.
2.Direct-cooled refrigerator.
Direct cooling refrigerators, on the other hand, use direct contact for refrigeration.
The refrigerant is sprayed directly on the evaporator and the temperature inside the refrigerator is lowered by heat exchange.
3. Comparison of the advantages and disadvantages of air-cooled refrigerators and direct-cooled refrigerators
1. Advantages of air-cooled refrigerators:
1) Better refrigeration effect: The air-cooled refrigerator blows the cold air into the inside of the refrigerator through the fan, which makes the refrigeration more uniform and the food keeps it fresher.
2) Frost-free refrigeration: The air duct design is used inside the air-cooled refrigerator, and the water is not easy to condense during the refrigeration process, so the frost-free refrigeration effect is better.
3) Easy to clean: There is no frost inside the air-cooled refrigerator, and you only need to wipe it when cleaning, saving the trouble of removing frost.
2. Disadvantages of air-cooled refrigerators:
1) Higher energy consumption: The fan of the air-cooled refrigerator needs to consume a certain amount of electricity, which is higher than that of the direct-cooled refrigerator.
2) Slightly louder: The fan of the air-cooled refrigerator will produce a certain amount of noise when it is running, which will have a certain impact on the quality of life.
3. Advantages of direct cooling refrigerator:
1) Low energy consumption: Direct cooling refrigerators do not need a fan for blowing, and the energy consumption is relatively low.
2) Less noise: The direct-cooling refrigerator does not need a fan to operate, so it is less noisy.
4. Disadvantages of direct cooling refrigerators:
1) Uneven refrigeration: The refrigeration effect of the direct cooling refrigerator is affected by the evaporator area and the spraying of refrigerant, and the refrigeration effect is relatively poor.
2) Easy frosting: The evaporator of the direct cooling refrigerator is in direct contact with the inside of the refrigerator, and the moisture is easy to condense, resulting in frosting inside the refrigerator and affecting the refrigeration effect.
Fourth, purchase suggestions
To sum up, air-cooled refrigerators and direct-cooled refrigerators have their own advantages and disadvantages.
When it comes to purchasing, consumers can choose according to their needs and budget.
If you're concerned about refrigeration, ease of cleaning, and frost-free refrigeration, then an air-cooled refrigerator is a good choice.
And if you're concerned about energy consumption, noise, and cooling costs, then a direct-cooling refrigerator may be more suitable for you.
In short, when buying a refrigerator, you should decide according to your actual needs and preferences, and you don't have to be too entangled in the choice of air cooling and direct cooling.
As long as the refrigerator is of reliable quality and stable performance, it can meet your needs.
