Which type of refrigerator cooling type is good?

Question 1: Which refrigerator cooling type is good The refrigerator cooling method is mainly divided into direct cooling and air-cooled type two.

Direct-cooled refrigerator through the evaporator, absorbing heat for cooling, while the air-cooled refrigerator is mainly used in the forced air convection cooling method, through the fan of the air supply, so that the whole refrigerator inside the stability of the expected, so as to cool down.

The air-cooled refrigerator due to more fan air supply, so the refrigerator indoor temperature is more average, there is no big temperature change, the cooling effect is also naturally better, while taking into account the role of the fan, the air-cooled refrigerator refrigeration speed naturally wear to be faster than the direct-cooled refrigerator. However, also taking into account the role of the fan and complex line design, air-cooled refrigerator in the energy consumption and noise compared to direct-cooled refrigerator is much higher. At the same time, we should note that the fan for food drying effect is also we can not ignore, so the air-cooled refrigerator food to dry relatively faster.

The air-cooled refrigerator is the one that excels in defrosting.

Nowadays, there are some refrigerators that use traditional direct cooling in the freezer, and air-cooled cooling in the freezer. This way the fruits and vegetables in the freezer will not dry out easily and the freezer will not frost. This wind direct cooling refrigeration method of refrigerator is relatively scientific, you can consider when buying.

Question 2: What kind of refrigerator refrigeration is good 1, direct cooling: you can see that there are rows of refrigeration piping between the drawers of the freezer, no drawer of the refrigerator, these piping in the outer layer of the freezer liner. Direct cooling is the earliest refrigeration technology, the advantages of a simple structure, low cost, food is not easy to dry the freshness of the effect is better, the disadvantage is that the temperature inside the box is not very uniform.

2, air-cooled: refrigeration piping hidden, the use of fans to blow cold air into the freezer and refrigerator, the advantage is that the temperature inside the box is uniform, high refrigeration efficiency (similar to the hot water blowing cooling fast reasoning based on the structure is complex, high cost. Higher-grade refrigerator to take more air-cooled technology, such as the door to the 400-liter refrigerator is commonly used.

3, between the direct cooling hybrid: the use of the advantages of the above two refrigeration methods, freezer with air-cooled, freezer with direct cooling. This way of technical complexity, less common.

Question 3: Which is a good way to refrigerate the refrigerator? Air-cooled refrigerator refrigeration is good, our family just bought the eleven, Haier 290W that, 2 plant 0 liter capacity, large ah, and refrigeration fast, and have not seen the previous kind of ice cubes on the inner wall

Problem 4: Refrigerator which refrigeration control system is good How do you say it, machine-controlled refrigerator is simple to use and easy to operate, but the temperature control is not so precise, and you can not intuitively understand the refrigerator's operating conditions and temperatures. The computerized refrigerator is accurate in controlling temperature. Computerized temperature control refrigerator, temperature control is accurate, the operation is also considered convenient, but for the middle-aged and elderly, there may be some obstacles to use.

But the more features of the product, the higher the probability of failure, the more difficult to repair, the higher the cost of repair, this is proportional to stare. Which temperature control you choose depends on your own preferences.

Question 5: What kind of refrigeration is the majority of refrigerators now? Refrigerator refrigeration

Refrigeration refrigerator refrigeration mode has direct cooling (frost) and air-cooled (frost-free) two kinds. China's early introduction of refrigerator manufacturing technology is mostly direct cooling with frost type. Therefore, a large part of the domestic refrigerator on the market is still direct cooling frost refrigerator. At present, China's refrigerator consumer market has entered a period of renewal, more advanced technology, more convenient to use, higher grade frost-free refrigerator, gradually become the mainstream market products. Generally speaking, 120L below the small refrigerator by the production cost constraints, can consider choosing direct cooling refrigerator, also more affordable, and medium and large refrigerator choose frost-free refrigerator is better. The larger the volume, the frost-free refrigerator has the advantages of uniform cold distribution, freezing effect is more prominent. In addition, in the choice of freezing method to learn to identify, the easiest way is to pay attention to the model there is no letter "W". Such as "BCD-182W", the top of the W in the meaning of frost-free refrigerator.

Question 6: What is the difference between direct cooling and air-cooled refrigerators? Which is better for home use? 1. Direct cooling refrigeration type. By the evaporator surface low temperature natural convection, reduce the temperature inside the box, but the temperature is not uniform. Gong for power saving, the same volume, the effective volume is large. 2. air-cooled refrigeration. Cold air is forced to blow into the box space by the air duct, resulting in circulation, temperature uniformity. Freezer automatic defrost low humidity, food is easy to air dry dehydration, suitable for humid areas. Power consumption is higher than direct cooling type, the same volume, the effective volume is small. 3. direct cooling air-cooled refrigeration. Is a computerized temperature-controlled double-cycle system, set air-cooled, direct cooling refrigeration in one, the refrigerator frost-free, freshness and good results. It makes full use of and centralized cold, alone on the freezer room direct cold, cold on the freezer room air cooling, especially equipped with two dynamic cooling system, intelligent dual dynamic cooling, regardless of the freezer room, freezer room cold as fast as uniformly sent to each corner, quick cooling and freezing, cooling rapidly.

Question 7: What kinds of refrigerator refrigeration, which is good Refrigerator cooling can be divided into:

direct cooling (i.e., natural convection) refrigerator;

inter-cooling (i.e., forced convection of air-cooled) refrigerator, also known as the air-cooled refrigerator, frost-free refrigerator;

wind-direct cooling refrigerator, including direct cooling, air-cooled cooling mode.

1, direct-cooled refrigerator: simple structure, low price, freezing and cooling speed, low power consumption, low noise, but the freezer room cooling is slow, the temperature inside the box is not uniform, the freezer evaporator is easy to frost, need to frost frequently.

2, air-cooled refrigerator: air-cooled because it has a fan in the freezer. There is an automatic defrosting device, easy to use, the freezer cools down quickly, the temperature inside the box is uniform, good refrigerator function, but the freezer freezes but the speed is slower than the direct cooling refrigerator, food is easy to air-drying, the structure is complex, power consumption, the price is higher.

3, wind direct cooling hybrid refrigerator: a combination of the advantages of the first two refrigerators, freezer for direct cooling, food moisture is not easy to lose, freezer for the air-cooled, do not need regular defrost, the price is also the highest.

Question 8: What is the difference between air-cooled and direct-cooled refrigerators, and which is better? Air-cooled is the cold wind blowing to the items inside the refrigerator, direct cooling is the refrigerator internal wall cooling passes to the internal food, you if you buy, it is recommended that you buy a direct-cooled, fewer failures, maintenance Foyi, air-cooled internal circuitry is complex, maintenance trouble (the advantage of the food can be uniformly cooled and will not be frost, the loss of nutrients is less, however, not very practical, often occurs when the temperature does not reach)

Question 9: refrigerator according to the cooling method is divided into which kinds? What are the characteristics of each? Refrigerators are generally divided into direct-cooled and air-cooled frost-free two types, direct-cooled refrigerator power consumption is low, the cooling speed is slower, the freezer is more humid, the fruit and vegetable class preservation is good, but the freezer needs to be manually defrosted. The air-cooled refrigerator is relying on the fan to blow the cold air out of the evaporator, so the cooling is fast, the temperature is uniform, generally 24 hours on the evaporator automatically defrosted once, do not need to manually defrost, so the power consumption is larger, in addition to the refrigerator room humidity is poor, the food is easy to be air-drying, the preservation of fruits and vegetables is not good.

Question 10: What kinds of refrigerants are commonly used in air conditioners and refrigerators? Refrigerant R12, R22, R13 sea a, R152a, R600a, h-01, RH, H, R404, R401, R152a and R22 mixed refrigerant.

Commonly used refrigerants are R12. R22. R134a. R152a. R600a. generally can be replaced by R12. R22

R152a. H-01. RH. H. R404.

R404. refrigerant blend of R152a and R22, can be replaced with R22.

R12 and R22 are generally not interchangeable.

Refrigerators commonly used refrigerants are R12, R134, R600, R152/R22*** boil

Air conditioners commonly used refrigerants are R22, new refrigerants are R404

Refrigerator repair can be replaced with R12

R134 system substitution shall be replaced with the compressor system, mainly the difference between the refrigeration oil, so clean the The pipeline.

Air conditioning repair R404 special, manufacturers do not allow the replacement of R22.
