How much do you know about refrigerators?
Air cooling and direct cooling have their own advantages and disadvantages, each with its advantages. Here only list the advantages and disadvantages of air-cooled and direct-cooled, for your reference, when choosing a refrigerator, it is best to choose the right one for your own situation.
First, the demarcation point between air-cooling and direct-cooling is about 300 liters, and air-cooled large-capacity rooms have advantages.
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 direct cold room is 3 basic to the limit. If you want to do more rooms, you will sacrifice some performance. So don't believe it in the direct-freezer refrigerators in some large-capacity rooms (even drawers) on the market. Such products are not uncommon on the market, and they are mostly concentrated on small-brand products. They are mainly sold in the third and fourth-tier markets. Some large cities are also seen in the surrounding and home appliance wholesale markets.
Third, the air-cooled refrigerator due to more fan air, so the refrigerator temperature is relatively average, there is no great temperature changes, cooling effect is also relatively good, but also take into account the role of fans and complex circuit design, air-cooled Refrigerators are much higher in energy consumption and noise than direct-cooled refrigerators.
Four, direct-cooled type because there is no electric fan, will not produce extra noise and power consumption, but also will not cause the dry phenomenon on the food surface due to blowing.
Fifth, the air cooling is forced by the cold air circulation, so the cooling speed, the temperature balance is good, this is its inherent advantages, direct cooling can not be compared. Since direct cooling is due to natural convection, the temperature balance is relatively poor and the cooling rate is relatively low.
VI. The inherent defrosting cycle of air-cooling, fans, and multiple compensation heaters inside cause power consumption and noise to be higher than that of a direct-freezer, so similarly, air-cooling certainly has no advantage in these two categories. National and international standards for refrigerator performance and energy consumption are well aware of this. Therefore, blowing air cooling is lower than the direct cooling energy consumption and noise, but it is not under the same conditions.
Seven, direct-cooled manual defrosting really suspected, the so-called micro-frost design is only the use of the entire drawer only to reduce the air flow in the open box to reduce frost. Even if this is done for half a year, it will require defrosting. If the number of door openings is small, it can be prolonged and vice versa. Frosting can also become serious if the door seal is not good or is aging. With the extension of time, the number of defrosting will increase.
VIII. Air cooling Due to the forced circulation of air, the odor will be shaken in all rooms. Dual-system air-cooled refrigerators have begun to become popular, and separation between freezing and refrigeration is better.
Nine, air-cooled refrigerators constantly bring the moisture inside the box to the evaporator, and then flow away when the defrosting, resulting in the box inside the dry consumption, is not conducive to preservation, which is also the inherent shortcomings of air-cooled. Although there are also some so-called preservation techniques, but in a small area (such as a relatively sealed space), do not allow cold air to enter, only from the surrounding, the space is actually close to the natural convection, but the direct cooling of a small space Only.
