Energy conservation is the last word to open the concept of mist selection refrigerator

The concept of refrigerator products in the market is constantly emerging. Among them, the function of keeping freshness is even more powerful than that of Dong Fangzhong and the refrigerator. At the same time, the concept of refrigerators is also emerging. This makes consumers feel somewhat confused. Recently, a “Fridge Purchase and Fresh-keeping Effect in 2012” survey showed that nearly 60% of users have misunderstood the use of refrigerators, and advanced refrigerator technology has caused consumers to be indifferent to the various concept publicity. In fact, it is not so difficult to understand the new technologies and new functions that are called differently because of the fog of concepts.

Energy conservation is the last word

Energy-saving housekeeper, energy-saving superman, vector frequency conversion, DC inverter ... a concept about energy saving, manufacturers have come up with a variety of terms to express. In fact, these concepts are not important. The important thing is the daily power consumption and energy efficiency level of the refrigerator.

The reporter saw an energy-saving expression on the refrigerator's promotional materials: "The energy-saving housekeeper uses an international energy-saving compressor and an encryption-efficient wire-tube evaporator, which are particularly effective in cooling, and is an important hardware support for the refrigeration effect. The cooling speed and the frequency of on/off operations have been significantly reduced, which is energy-saving and efficient.” But after an interview, a consumer said after reading: “I really didn’t understand it, I just knew that this refrigerator saves electricity, the specific technology used, The effect is not clear to me."

A salesperson told reporters: “I sell refrigerators every day, explaining different concepts to consumers every day. There are several references to frequency conversion, consumers are not faint. To me, energy consumption depends on the power consumption. No matter what technology is used, consumers will only look at the results. Whoever has a high level of energy efficiency and whose daily power consumption is less is the best.”

It is understood that the newly revised GB12021.2-2008 “Frequency Limitation and Energy Efficiency Rating of Household Refrigerators” divides the refrigerator into 5 levels of energy efficiency, and Level 1 is the most energy-saving product.

According to experts from Gome, the energy consumption of products with the same level of energy efficiency is not the same (only the lower limit is not the upper limit). For example, between the daily power consumption of 0.60 degrees and the daily power consumption of 0.39 degrees is considered as a level 1 energy efficiency, but There is obviously a big gap in power consumption.

Even if the overall volume is the same, comparing the energy-saving effect of the refrigerator, the size of the freezer compartment must be taken into special consideration. Two refrigerators with the same power consumption, the greater the energy saving effect of the freezer compartment, the better. For example, a refrigerator with an effective volume of 200 liters and a daily power consumption of 0.49 degrees is compared with a refrigerator with an effective volume of 250 liters and a daily power consumption of 0.58 degrees, as if the daily power consumption is 0.49 degrees. The product is more energy-efficient, but after considering the effective volume, the latter is actually more energy-efficient.

The door is not as good as possible

The concept of the refrigerator market is everywhere, and now even the refrigerator door has played a new concept, what drawer refrigerator, multi-door refrigerator and so on. The reporter found that these new concepts are nothing more than changing the door to a drawer, or just opening a few more doors.

Consumers in the interview stated that the refrigerators are getting bigger and bigger, and that there are more and more doors, and some have drawers and doors. It looks rather stylish, but you don’t know how much of the door is so useful.

According to experts, in fact, for consumers, the more refrigerator doors, the more drawers the better, the key depends on the size of the consumer's home, how much the population, and the usual lifestyle to decide to buy Several doors open the refrigerator. For example, families who do not drink red wine do not need to bring red wine to the refrigerator, which means that they can reduce floor space and energy consumption.

Studies have shown that the volume of refrigerators used by everyone is about 70-80 liters per day. Generally speaking, a family of three buys refrigerators, and 210-240 liters is enough. Refrigerators are too big and storing too much food can cause food updates to be untimely and not good for your health.

According to relevant statistics from Gome, the 220-liter three-door refrigerator has become the mainstream of consumption, especially in the primary market, and it is expected that the sales volume of the three-door and side-by-door refrigerators will increase from the original 50% to more than 60% this year. In addition, although consumers choose to gradually increase the refrigerator, but most consumers are still paying attention to the purchase of affordable.

Preservation technology is not

Preservation is now the focus of all kinds of refrigerators' propaganda, and natural concepts are also dazzling. However, behind the careful analysis of different concepts, the principles used are similar.

A salesperson told reporters that, in fact, many concepts are now different, but the results are not too bad, a little complicated the simple meaning of the problem.

The reporter saw that all kinds of refrigerators can be described as various aspects of preservation of publicity: moisturizing, preservation, odor, VC freshener sustained release of vitamin preservatives, prevent fruit and vegetable acidification reactions, long-term maintenance of food in a nutritious and tasty state. Photosynthetic and fresh-keeping photosynthesis of simulated plants, release seven kinds of beneficial light waves, promote their re-growth, and greatly increase the nutrients of fruits and vegetables.

According to relevant experts, these seemingly incomprehensible concepts are in the final analysis nonetheless the three major issues affecting the preservation of wind, water and light. For example, some refrigerators only have outlets on the top. Such refrigerators, because of the barriers that result from placing foods on each floor, can cause uneven air-conditioning and can easily dry food. The above concept uses multi-layer air ducts for the refrigerator. The air outlets are located on both sides of the cold room. The air-conditioning can evenly reach every corner, and the air-conditioning will not blow on the food, but it will be blown against the inner wall of the side, so it is not easy to dry the food. Keep it fresh longer. For another example, the magic crisper lid design features a unique two-way adjustment of moisture to prevent moisture from condensing into dew, adhere to the inside of the shelf to absorb or release water vapor in a timely manner, effectively maintain the water balance in the fruit and vegetable room, and extend the shelf life. "Fresh Cube" effectively prevents and delays the metabolism of fruits and vegetables ... The concept is like saying that the refrigerator can reduce the evaporation of food by certain technical means, and prevent the food from drying out and maintain freshness.

Refrigeration issues should not be complicated

"DICS dual independent circulatory system, more accurate temperature control, cooling is also more rapid, frost-free air-cooled design, but also eliminates the trouble of manual defrosting; double refrigeration system independent precise temperature control, using the freezer, freezer respectively Independent cooling system; Zhinong navigation function, through the refrigerator on the 3 sensors to observe and record the user's refrigerator status, according to their habits, intelligent switching, adjusting the refrigerator to achieve efficient cooling operation state ... ..." reporter found that in the election When buying a refrigerator, the refrigeration effect of the refrigerator and the presence or absence of frosting are all of concern to consumers. However, because the concept statement is too complicated, consumers want to pay attention but do not know where to start.

In a home appliance store, a consumer told reporters that he had taken a few refrigerator promotional materials. It was indeed impossible to understand, and he did not know which one to choose. The reporter also read these statements about the cooling function is indeed unclear.

According to reports, some frost-free air-cooled refrigerators are currently used to remove the frost condensed on the evaporator, mainly by thermal evaporation. When the refrigerator is working for a period of time, the refrigeration is suspended, and the defrost heating system is automatically activated. The condensed cream will become water after being heated and then be discharged through a special duct. These operations are performed automatically by the refrigerator and do not require manual processing by the user. In other words, there is no frost on the inner surface of the frost-free surface, and the surface of the evaporator is still frosted, but the automatic defrosting is performed on a regular basis without manual defrosting. The use of air-cooled circulation refrigeration refrigerator is what we call the frost-free refrigerator. The evaporator of the frost-free refrigerator is usually finned and placed in the sandwich between the freezer and the freezer or in the upper part of the box. A small fan is used to force air convection in the box to achieve the purpose of cooling, so there is no frost produce.
