Refrigerator can be said to be one of the indispensable appliances in life, and its utilization rate is still extremely high. At present, the four-door refrigerator is the first choice for "fashion" and "big space" storage. However, the price of the same four-door refrigerator on the market is quite different. More than 3000 refrigerators, 65438+100000. What's the difference between two refrigerators with different prices?
If you want to know the difference between the same four-door refrigerator, I think it is necessary to analyze it in detail from three aspects: compressor type, circulation system and intelligent components, so as to get a comprehensive answer.
First, the compressor type
For the refrigerator, if you want to achieve the cooling effect, you can't do without the compressor, which is similar to air conditioning. Then, as long as the compressor is used, there will naturally be a distinction between "fixed frequency" and "variable frequency", which will naturally lead to price differences, which is also the main reason for the price differences of refrigerators.
⑴. Refrigerator "fixed frequency" compressor: For refrigerators, the initial compressors are basically fixed frequency. As long as the rotational speed of the compressor is fixed after the refrigerator is turned on, the compressor will stop running unless the refrigerator is turned off. This mode will make the compressor operation technology of fixed frequency air conditioner become a very similar technology. For this kind of compressor operation technology, it is now very backward, and naturally it is only used in the application of low-end refrigerators, and the price will naturally be very cheap. The refrigerator adopts the technology of constant frequency compressor, so the temperature cannot be accurately controlled during operation. Therefore, the food in the refrigerator can not be kept fresh for a long time, but it is suitable for frozen ingredients, which is one of the important reasons why the fresh-keeping ability of cheap refrigerators is very general.
⑵. Refrigerator "frequency conversion" compressor: For refrigerators, the best compressor technology at present is frequency conversion, which is also a refrigeration technology similar to air conditioning. Through the application of variable frequency compressor, it can automatically and flexibly change according to different refrigeration requirements. After using the frequency conversion compressor technology, for refrigerators, this technology can not only achieve the advantage of saving electricity, but also achieve more accurate temperature control and ensure the freshness of food in the refrigerator, which is also one of the main reasons why refrigerators with high prices perform well in preservation. For the current high-end brand refrigerators, the compressors used are all imported brands, which ensure the technical requirements to a certain extent, and the price will not be cheap.
Second, the circulatory system
The same four-door refrigerator, some can sell more than 1000, and some only sell more than 3000, which is such a big difference. Another main reason is the circulation system of the refrigerator. At present, there are three modes of refrigerator circulation system, namely, single-cycle air-cooling mode, multi-cycle air-cooling mode and dual-machine refrigeration multi-cycle mode.
⑴. Single-cycle air cooling mode: The so-called single cycle means that the freezing room, refrigerating room and variable temperature room share the same air duct, and all belong to the loop mode structure type of refrigeration. For this investment cycle model, most of them are used in low-end refrigerators, so as to make refrigerators cheaper. After using this circulation mode, there will be a series of problems such as frosting, odor and water loss, which will lead to the loss of the original taste of food.
⑵. Multi-circulation air cooling mode: The so-called multi-circulation mode means that the three rooms of freezing, cold storage and temperature change have their own independent air circulation systems. For multi-cycle mode, it is a system mode used by many domestic brands, including high-end refrigerators of foreign brands. Although the multi-cycle mode has been technically improved, the cost is very low, but the merchants sell this low-cost technology at a high price, and use this technology to increase the price of refrigerators in disguise, which is one of the main reasons for the large price difference between refrigerators.
⑶. Dual-machine refrigeration multi-cycle mode: For the highest-end refrigerator, the dual-machine refrigeration multi-cycle mode is adopted. The so-called double-machine refrigeration multi-cycle mode means that both refrigeration and refrigeration are equipped with an independent compressor and operate independently. With this technology, it has performed extremely well in the refrigeration of refrigerators, and at the same time it can save electricity, which is conducive to food preservation. The only drawback is the high price of the refrigerator. After all, the manufacturing cost is also high, and it will naturally not be cheap to sell abroad. Moreover, refrigerators that can use this technology are often the highest-end models, so the price is not the focus of attention.
Third, intelligent elements.
For the refrigerator industry, intelligent elements have been integrated into a lot, and it is also the focus of sales for merchants at present. After all, refrigerators have entered an intelligent era. There are also many people who will say that the basic functions of their refrigerators are the most practical, and engaging in these intelligent elements is not practical at all. This is actually a wrong idea. Just because you don't use it doesn't mean that others don't use it, and with the passage of time, the influence of intelligent elements on refrigerators is growing. After all, young people prefer to use this function.
⑴.wifi remote control: Whether it is a refrigerator with a price of 3,000 yuan or a refrigerator with a price of 65,438+100000, it is no stranger to the intelligent technology of realizing wifi remote control of refrigerators. However, the same wifi remote control technology will also have different effects because of the difference between the compressor and the circulation system of the refrigerator. For most low-end refrigerators, only the basic wifi remote control function is realized, which can not better control the internal temperature change and food temperature change technology, so it is only the surface wifi remote control. For high-end refrigerators, wifi remote control can remotely operate the refrigerator's temperature, mode, food preservation period, food purchase, etc., and truly realize the convenience brought by mobile phone operation and the function of food preservation.
⑵. Scene design: With the constant changes of functional kitchens and smart kitchens, the quality of life is constantly improving. For refrigerators, intelligent elements have begun to contribute to the ecological design of the scene. Through the built-in intelligent technology, the refrigerator can be connected with the body fat scale to obtain the user's body data such as weight and body fat, so as to customize healthy recipes, which also brings users a seamless high-end healthy diet life experience from the whole process of purchasing, storing, cooking and eating ingredients.
abstract
It is also a four-door refrigerator, some are more than 3,000, and some are more than 1000. The main differences are compressor type, circulation system and intelligent components. For other configurations of the refrigerator, it will also require automatic adjustment of the grade of the refrigerator, so there is no need to consider this separately.
I want to buy one with high cost performance, low price and low failure rate. The brands I recommend are Meiling and Haier, and the models are adjusted according to their actual purchase budget.
