Which one is better, Haier refrigerator uniform cooling or air cooling direct cooling?

At present, Haier's refrigerator ranks first in uniform cooling, followed by air-cooled, and third-ranked in direct cooling.

Direct cooling refrigerator: Direct cooling refrigeration is the earliest refrigeration technology, and the freezer drawer is placed directly on the evaporator partition; The advantage is that the structure is simple, the cost is low, and the preservation effect of the food is not easy to be air-dried, but the disadvantage is that the temperature in the box is not uniform, and it needs to be manually defrosted.

Air-cooled refrigerator: the refrigeration pipe is hidden, and a fan is used to blow cold air into the freezer and refrigerator; The advantages are that the temperature in the box is uniform, the refrigeration efficiency is high, and there is no need for manual defrosting, but the structure is complex, the cost is high, the power consumption is high, and the food is easy to dry and dehydrate.

Uniform cooling refrigerator: It is a new generation of refrigerator launched by Haier, its core technology is 4D uniform cooling technology, which subverts the traditional refrigeration method, hides the refrigeration pipe (evaporator) in the freezer, breaks through space limitations, has a larger refrigeration area, uniform temperature, fast refrigeration speed, and strong freezing capacity; At the same time, it is equipped with a dynamic moisturizing system to keep food fresh for a longer time.

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.

Straight cooling is super easy to frost; Uniform cold is slightly frosty; Air cold is really frost-free, there will never be frost.

Direct cooling means that the evaporator of the refrigerator freezer adopts a composite three-dimensional structure of multi-layer heat exchanger sheets, and fixes the set fins 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. The advantage is that the process box list, high efficiency, low efficiency; The disadvantage is that the evaporator is susceptible to collision, scraping, and corrosion, which causes leakage and affects the life.

The core technology of the uniform cooling refrigerator is the 4D uniform cooling and moisturizing technology, which subverts the traditional refrigeration method and hides the refrigeration pipe (evaporator) in the freezer room, breaking through the space limitation, the refrigeration area is larger, the temperature is uniform, the refrigeration speed is fast, and the freezing capacity is strong; At the same time, it is equipped with a dynamic moisturizing system to keep food fresh for a longer time.

The biggest advantage of air-cooled refrigerators is that they are frost-free. An air-cooled refrigerator won't always be wet on the inside like a refrigerated refrigerator, and the food won't stick to each other. Moreover, the air-cooled refrigerator will have a continuous circulation of cold air, and then through the filtration of the deodorization system, the internal odor will also remain fresh for a long time, and there will no longer be that pungent "refrigerator smell".

In addition, because the air-cooled refrigerator can be automatically defrosted, which can be said to greatly reduce the user's burden of manual defrosting, after all, defrosting the refrigerator is a hard work, and friends who have experienced it must have resonance, the air-cooled refrigerator solves this problem very well, but the disadvantage of the air-cooled refrigerator is that the food is easy to dry and lacks water, and the noise is slightly louder than that of the more expensive.

1. Direct cooling: also known as natural convection of cold air, the refrigerated room has an evaporator, the size of the evaporator is based on the size of the room and the temperature requirements to carry out a reasonable ratio, the cooling method is to cool the food through the natural convection of the cold air.

2. The manual defrosting of direct cooling is really annoying, and the so-called micro-frost design is just that the whole drawer is used for freezing, which reduces the air flow in the door opening box to reduce frosting. Even so, it is generally necessary to defrost for half a year, and if the number of doors is rarely opened, it can be extended, and vice versa. If the door seal is not good or aging, the frost will also become severe.

The number of defrosts will increase with longer use time.

3. Air cooling is really frost-free. There will never be frost. (If there is frost in the evaporator part, it will be automatically removed) 4. Uniform cooling is a slight frost. The degree has a lot to do with the indoor environment, opening and closing the door, etc. If it is not manually defrosted, the frost will not melt away and will accumulate thicker.

5. Air cooling is forced cooling, with accurate temperature balance, fast cooling and strong cooling capacity.

6. Air cooling is the development trend of refrigerators, and uniform cooling is a phased product to replace direct cooling.

The difference between direct air cooling and cloud cooling of Haier refrigerators is as follows:

1. Direct cooling refrigerator, freezer evaporator is embossed aluminum plate evaporator, freezer drawer is directly placed on the aluminum plate evaporator.

2. The evaporator of the air-cooled refrigerator covering the freezer is attached to the back, and there is an air outlet on the back of the freezer.

3. The uniform cooling refrigerator adopts 4D uniform cooling technology, the evaporator of the freezer is wound on the inner tank, and there is no evaporator and no air outlet in the freezer, only the freezer drawer and glass partition.

4. The space for uniform cooling is limited, the refrigeration area is larger, the temperature is uniform, the refrigeration speed is fast, and the freezing capacity is strong. At the same time, it is equipped with a dynamic moisturizing system to keep food fresh for a longer time.

5. Energy-saving and power-saving comparison of air-cooled frost-free DC inverter compressor.

A refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. Inside the box there is a compressor, a cabinet or box for ice making for icing, and a storage box with a refrigeration unit. The volume of a household refrigerator is usually 20 500 liters.

When using the refrigerator, users should regularly clean and maintain the refrigerator and disinfect their breath, which is not only hygienic and clean, but also can prolong the service life of the refrigerator.

9 Steps to Clean Your Refrigerator:

1. It is best to clean the refrigerator shell every day, and wipe the refrigerator shell and handle with a slightly damp and soft cloth every day.

2. Cut off the power supply before cleaning the inner tank and take out the food in the refrigerator.

3. Dip a soft cloth in water or utensils dish soap, gently wipe and rinse, and then dip it in water to wipe off the dish soap.

4. Remove the accessories in the box and clean them with water or detergent.

5. When cleaning the refrigerator's "switches", "lights" and "thermostats", please wring out a rag or sponge.

6. After the inner wall is cleaned, you can use a soft cloth dipped in glycerin (medical corkscrew) to wipe the inner wall of the refrigerator, and it will be easier to wipe it next time.

7. Clean and wipe the sealing strip with an alcohol-soaked cloth. If you don't have alcohol on hand, wipe the sealing strip with 1:1 vinegar water, the disinfection effect is good.

8. Use a vacuum cleaner or soft brush to clean the ventilation grille on the back of the refrigerator, do not use a damp cloth to avoid rust.

9. After cleaning, plug in the power supply and check whether the temperature controller is set in the correct position.

Haier refrigerators can be divided into three types: direct cooling, air cooling and cloud cooling according to different refrigeration methods.

1.Direct cooling refrigerator: Directly put the condenser tube into the freezer to naturally dissipate heat.

This method of refrigeration is fast, but it will produce frost during the refrigeration process, and it will need to be defrosted and cleaned at regular intervals. If you have purchased a direct-cooling refrigerator, looking inside the refrigerator will clearly see the condenser tube passing through the freezer wall.

2.Air-cooled refrigerator: The indoor air is circulated through the electric fan to make the cooling effect more uniform. This eliminates the need for frequent defrosting. If you are buying an air-cooled refrigerator, you can pay attention to whether there are any vents in the back.

3.Cloud-cooled refrigerator: Split design is adopted, and the air generated by the external compressor accelerates the cooling of the refrigeration area and reduces the indoor temperature.

This method of defense makes the cooling effect better and saves energy. If you buy a cloud cooling refrigerator, you can check the official introduction or the official website of Haier to check the selection to understand the system.

In short, different types of Haier refrigerators use different technical methods to achieve refrigeration, and consumers can choose according to their needs and preferences. Of course, you should also learn more about the brand and cost-effective information and after-sales service before purchasing.

1. The temperature of the refrigerator is uniform, and the refrigeration area is increased to make the refrigeration more uniform, and the temperature of the freezer is guaranteed, the refrigeration speed is fast, the freezing capacity is strong, and the food is stored for a longer time. The free space freezer adopts to break through the limitations of traditional partition refrigeration pipes, and solves the trouble of cutting and storing high-sensitivity stools for large-volume food. Dynamic moisturizing adopts Haier's original dynamic moisturizing technology, which transfers the water vapor from the freezer to the refrigerator in one direction.

2. The biggest advantage of the air-cooled refrigerator is that it is frost-free. An air-cooled refrigerator will not be as moist as a refrigerator, and the food will not stick to each other. Moreover, the air-cooled refrigerator will have a continuous circulation of cold air, and then through the filtration of the deodorization system, the internal odor will also remain fresh for a long time, and there will no longer be that pungent "refrigerator smell".

3. The direct cooling refrigerator divides the freezer into a variable temperature chamber according to 1 to 1, and the temperature sensor controls the bistable solenoid valve of Qi Brigade to switch the refrigerant circuit, and the variable temperature chamber is frozen, soft frozen, and refrigerated, and can also be closed. With the help of the refrigeration system compressor, the evaporator load is matched and its flow rate with the capillary refrigerant, and the power consumption is below the degree in the energy-saving state, and the minimum degree is reached.

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. <>
