Which is better fridge air cooling or direct cooling? Which is better, air cooling or direct cooling

The air-cooled refrigerator has more fan air supply, so the indoor temperature of the refrigerator is relatively average, there is no great temperature change, and the refrigeration effect is naturally excellent. Therefore, with its forced circulation of cold air, fast cooling speed and good temperature uniformity, it can meet the multi-door models with large volume and many compartments. The types of refrigerators are divided into direct cooling refrigerators, air-cooled refrigerators and hybrid refrigerators, and there are fewer models of hybrid refrigerators on the market, most of them are direct cooling refrigerators and air-cooled refrigerators, which is better, refrigerator air cooling or direct cooling?

Here's a detailed answer. Direct cooling refrigerator Direct cooling refrigerator is an old-fashioned refrigerator, you can directly see the refrigeration pipe, after the cold air in the box and the refrigeration pipe contact, it will form frost, which needs to be manually defrosted. Air-cooled refrigeratorAir-cooled refrigerators are also refrigerated by evaporators, which will also form frost, but the evaporator of air-cooled refrigerators is hidden in the air duct, and the frost produced is on top of the evaporator rather than inside the refrigerator, and can be defrosted through the drain pipe or by evaporating the frost into water vapor, so there is no need for manual defrosting.

Mixed cold refrigerator Mixed cold refrigerator is also known as semi-air cooled refrigerator, its refrigerator is directly cooled, and the freezer is air cooled, which not only solves the problem of insufficient refrigeration and preservation, but also solves the problem of frost in the freezer. However, the structure of the hybrid refrigerator is relatively complex, the production cost and after-sales maintenance cost are relatively high, and most manufacturers are unwilling to produce, so there are few models of hybrid refrigerators on the market. Which is better, air cooling or direct cooling in the refrigerator, the following aspects are mainly considered.

Whether to defrost If the number of people in the family is relatively large and you need to use a large-capacity refrigerator, then, if you choose a direct cooling refrigerator, it will produce more frost, and the direct cooling refrigerator needs to be manually defrosted, which will be a headache. Therefore, if it is a large-capacity refrigerator, it is recommended to choose an air-cooled refrigerator, which does not require manual defrosting. The preservation effect of food is that the direct cooling refrigerator cools down through heat exchange, and the cooling speed is fast, which can make the food enter the state of preservation faster.

Air-cooled refrigerators cool down by blowing cold air, and in the state of blowing, the food is also prone to lose a certain amount of moisture, which also leads to a decrease in the freshness of the food. Therefore, if you have higher requirements for the preservation effect of food, you can choose a direct cooling refrigerator. Refrigeration temperature: Because the air-cooled refrigerator is cooled by blowing cold air, the temperature in the refrigerator is relatively uniform, and it can achieve uniform cooling effect on all food.

Direct cooling refrigerators, on the other hand, use the temperature difference between the inner walls to cool down, and the temperature may vary from place to place in the refrigerator. As a result, air-cooled refrigerators have more precise temperature control and less temperature fluctuations than direct-cooled refrigerators. The failure rate of the direct cooling refrigerator is an old-fashioned refrigerator, therefore, the structure is relatively simple, and the refrigeration process is relatively mature, so the probability of failure is relatively low, and the maintenance cost is also low.

If you want to buy it for the elderly at home, you can also choose a direct cooling refrigerator.

Air cooling and direct cooling have their own advantages and disadvantages, and each has its own advantages. The following lists the advantages and disadvantages of air cooling and direct cooling.

1. The dividing point between air cooling and direct cooling is about 300 liters, and large-volume multi-room air cooling has the advantage.

Second, the volume is large, there are many compartments, and air cooling has an absolute advantage in the distribution of cooling capacity. If direct cooling is used, there will be technical obstacles, and it is not easy to achieve. The 3 direct cooling compartments are basically at the limit, and if you want to make more compartments, you will sacrifice some performance.

So don't believe some of the most spacious multi-compartment (or even drawer-door) direct-cooling refrigerators on the market. This kind of product is not uncommon in the market, and it is mostly concentrated in the products of small brands, and the main sales are in the third and fourth tier markets. It can also be seen in the vicinity of some large cities and in wholesale home appliance markets.

3. The air-cooled refrigerator has more air supply from the fan, so the indoor temperature of the refrigerator is relatively average, there is no great temperature change, and the refrigeration effect is naturally excellent, but also considering the role of the fan and the complex circuit design, the air-cooled refrigerator is much higher than the direct-cooled refrigerator in terms of energy consumption and noise.

Fourth, because there is no electric fan, the air-cooled type will not produce additional noise and power consumption, and will not cause drying on the surface of the food due to blowing.

Fifth, air cooling is a forced circulation of cold air, so the cooling speed is fast, the temperature balance is good, which is its inherent advantage, direct cooling can not be compared. However, due to the natural convection, the temperature balance is relatively poor, and the cooling rate is relatively low.

It's still good to be cold straight. The frozen things in the air-cold refrigerator always feel dry, and the things frozen out of the cold refrigerator are the same as fresh after they are slowly opened.

Refrigerator choice direct cooling or air cooling: direct cooling is suitable for small-capacity refrigerators, it has the advantages of low manufacturing cost, good fresh-keeping effect and low power consumption. The air-cooled type is suitable for large-capacity refrigerators, it does not need to be defrosted, it is clean and refreshing, the refrigeration is uniform, and the food will not freeze together, which greatly reduces the phenomenon of cross-flavor.

Direct-cooled refrigerators produce frost ice, whereas air-cooled refrigerators have no frost inside. The direct cooling refrigerator is cooled by answering the heat exchange of socks, and the cooling speed is fast, and the food enters the freshness state faster. The air-cooled refrigerator is cooled by blowing cold air, and in the state of blowing, the food is easy to lose water, thereby reducing the freshness of the food.

The air-cooled refrigerator is dry blowing cold air, so the temperature inside the refrigerator is more uniform, while there will be a certain temperature difference in various parts of the direct cooling refrigerator. The direct cooling refrigerator is a more traditional refrigerator, and the refrigeration process is also more mature and simple, so the failure rate is also low.

Direct-cooled refrigerator. The direct cooling refrigerator cools down through heat exchange, so the cooling speed is fast, and the food enters the freshness state faster. Moreover, the direct cooling refrigerator is a traditional refrigerator, so the refrigeration technology is mature and the structure is simple, so the failure rate is low and the power consumption is relatively small.

Air-cooled refrigerators are slightly louder due to the operation of the internal fan to supply air. Direct-cooling refrigerators, on the other hand, do not need a fan to supply air, and rely on the evaporator cooling pipe attached to the inside to absorb heat for cooling, and the noise generated is very small.

The principle of direct cooling:

1. It refers to the composite three-dimensional structure of multi-layer heat exchanger plate in the evaporator of the refrigerator freezer, and the set of fins is fixed on the outside of the S-type refrigeration coil wall to increase the refrigeration capacity of the two high-temperature areas at the top and low part of the freezer.

2. The cold positive group freezer is divided into a variable temperature chamber according to 1: family cultivation 1, and the refrigerant circuit switch is realized by controlling the bistable solenoid valve through the temperature sensor, and the variable temperature chamber can be used according to freezing, soft freezing, and refrigeration, and it can also be closed.

3. Through the design of the wire tube condenser with horizontal and vertical coil mixed structure, with the help of the load matching of the compressor, condenser and evaporator of the refrigeration system and the matching of the flow rate with the capillary refrigerant, through the design of the direction and position of the anti-condensation pipe, the position and direction of the evaporator pipe and the design of the return air heat exchanger, the maximum load daily power consumption of the BCD-186CHS direct cooling refrigerator is below the degree when the variable greenhouse is in an energy-saving state, and the power consumption is below the degree, and the minimum is reached. <>

To sum up, air-cooled refrigerators and direct-cooled refrigerators have their own advantages and disadvantages, and which one to choose depends on individual needs and budget. Air-cooled refrigerators are suitable for users who have high requirements for food preservation and sufficient budgets, while direct-cooled refrigerators are more suitable for users who pay attention to energy conservation and environmental protection.

Air-cooled refrigerators are the best, air-cooled refrigerators are more advanced refrigeration methods, with high refrigeration efficiency, fast speed, and uniform temperature distribution.

Let's compare the three refrigeration methods of refrigerators:

1. Direct cooling type:

This is the most old-fashioned and most common refrigeration method, mainly through the evaporator and condenser tube to achieve refrigeration, this kind of refrigerator has a simple structure, the power consumption is also very small, the preservation effect is not bad, the ** direct cooling refrigerator is often cheaper.

However, a large amount of frost will be formed during the refrigeration process, which needs to be cleaned regularly, and the temperature distribution in the refrigerator is not very uniform, and the food stored in the refrigerator will also smell with each other, as well as the deterioration of the food, resulting in peculiar odors and odors in the refrigerator.

2. Air-cooled:

This is the current more advanced refrigeration mode, the use of cold air cooling to achieve refrigeration, refrigeration efficiency is very high, the speed is fast, and the temperature distribution is uniform, but the structure of the knot is more complex, so the cost is relatively high, generally more hand shelter in the large capacity of the refrigerator, there are also a small number of three-door refrigerators, not only the refrigeration effect is good, but also the temperature control is also very accurate.

Inside the air-cooled refrigerator there is a small homemade fan, which works by automatically removing frost from the surface and does not freeze.

3. Hybrid:

At the same time, it takes into account the advantages of direct cooling and air cooling, the freezer adopts air-cooled, the refrigerator adopts direct cooling, the refrigeration efficiency is high, the fresh-keeping effect is also good, and the energy saving is very good, but the cost is also very high, so it is not widely used in the field of household refrigerators, and it is not suitable for general families.

All things considered, it is more practical to choose an air-cooled refrigerator, which has a very good effect on the preservation of food.

Air-cooled refrigerators and direct-cooled refrigerators have their own advantages and disadvantages, and which type is better to choose depends on individual needs and preferences.

Air-cooled refrigerator:

Pros:1Uniform cooling: Air-cooled refrigerators evenly distribute cold air in various areas through fans, so that food can be cooled more evenly and avoid the problem of uneven refrigeration and freezing.

2.Temperature stability: Due to the way the air-cooled system works, the temperature of the air-cooled refrigerator changes less, and Sakurayu is better able to maintain the freshness and taste of the food.

3.Frost-free design: Air-cooled refrigerators typically have a frost-free feature that reduces condensation and ice build-up in the freezer compartment through circulating air and humidity control.

Cons: 1**Higher: Air-cooled refrigerators are typically taller than direct-cooled refrigerators due to the need for additional fans and cooling technology.

2.Higher energy consumption: Air-cooled refrigerators may be slightly higher in terms of energy consumption than direct-cooled refrigerators due to the need for additional fans and electricity to maintain cold air circulation.

Direct cooling refrigerator:

Pros:1Relatively low: Direct-cooled refrigerators are generally lower than air-cooled refrigerators.

2.Lower energy consumption: Direct-cooled refrigerators usually do not require the use of a fan and have relatively low energy consumption.

Cons: 1Uneven temperature: Due to the lack of a fan and circulation system, the temperature distribution within a direct-cooling refrigerator may not be uniform enough.

2.Easy to condensation: Due to the lack of frost-free technology, direct-cooling refrigerators are prone to condensation and ice accumulation in the freezer, so they need to be cleaned up regularly.

In summary, if you are more concerned about uniform cooling, temperature stability and frost-free function, then an air-cooled refrigerator may be more suitable for you. And if you're more concerned about budget and energy consumption, and can tolerate uneven temperatures and the need to thaw regularly, a direct-cooled refrigerator may be a better fit.

Air-cooled refrigerators and direct-cooled refrigerators have their own advantages and disadvantages, and the choice depends on individual needs and preferences.

Advantages of air-cooled refrigerators:

The cooling effect is good, the refrigeration speed is fast, and the freezing effect is more uniform;

Relatively low noise and quieter operation;

Electricity saving and environmental protection, energy saving and environmental protection.

Disadvantages of air-cooled refrigerators:

The structure is relatively complex, and the installation is difficult;

There is a lot of frost and it needs to be cleaned regularly.

Advantages of direct cooling::

Simple structure and easy installation;

The refrigeration speed is fast and the freezing effect is better;

No noise problem.

Disadvantages of direct cooling:

The cooling effect is relatively weak, and the freezing effect is uneven;

Whether it will frost and choose an air-cooled refrigerator or a direct-cooling refrigerator needs to consider the actual needs and uses of the individual. If you have high cooling requirements and prefer a quiet operating environment, then an air-cooled refrigerator may be more suitable for you. If you're more concerned about low freezing and noise, then a direct-cooling refrigerator may be a better fit for your needs.

In addition, there are also differences between the two, and you can choose according to your budget.
