The price is not important!
A few days ago, people in the industry pointed out that there was a lot of unrealistic publicity about refrigerators in the market, and almost all kinds of refrigerators were labeled as "green refrigerator", "environmental refrigerator", "fluorine-free refrigerator" and "energy-saving refrigerator", which was easy for consumers to misunderstand. To this end, industry insiders pointed out that the following issues deserve consumers' attention:
The degree of freezing should be practical.
Freezing capacity is an important technical index to measure refrigeration appliances. But refrigeration equipment has different uses. Compared with the special needs of commercial use and scientific research, the main technical performance of household refrigerators should not be refrigeration, but preservation. Excessive freezing force will not only increase electricity consumption unnecessarily, but also destroy the internal tissue and nutritional structure of food. For people who pay attention to color and fragrance, preservation is the first demand for consumers to buy refrigerators.
Expensive is not necessarily advanced.
Pursuing famous brands is the current consumption fashion. But famous brands don't mean high prices, especially refrigerators, which are mature technologies. The raw materials, manufacturing technology and quality performance of different brands are basically the same, so the manufacturing cost is also roughly the same. The factors that affect product prices are often soft costs, such as advertising expenses, internal management expenses and other factors, especially the management level of enterprises and the use of marketing strategies, which play a very important role in commodity prices.
The refrigerator is not "the more electricity you save, the better"
Like refrigeration power, the power consumption of refrigerator is also a very important performance index. However, in order to achieve the best preservation effect, it is not enough to make a fuss about reducing power consumption, but also to have optimized structure and refrigeration design.
Enterprises can achieve the purpose of saving electricity by adding simple measures such as insulation layer (the cost increases accordingly), and can also improve the energy efficiency ratio by adopting new technological achievements. Therefore, we can't unilaterally emphasize that "the more electricity is saved, the better"
Selection of refrigerator (1)
Nowadays, families are busy buying some home appliances when they get married and buy new houses, but how much do you know when you are busy buying these home appliances? I'll tell you how to buy a refrigerator now, so that you can buy an economical refrigerator suitable for your family.
First, the choice of refrigerator capacity and form
Capacity of refrigerator
Since the first refrigerator was first produced by Karl Wienert Company of the United States in 19 14, the capacity of the refrigerator has been developing to a large capacity. At present, the single-door refrigerator has been eliminated by the market, and the refrigerator of about 200 liters is generally only for single use. The market for refrigerators with 500-600 liters is growing, and at the same time, the size of the freezer will also increase.
In China's current national standards for refrigerators, the volume of refrigerators is expressed by effective volume. The so-called effective volume refers to the volume inside the refrigerator that can actually be used to store food.
The capacity of the refrigerator is generally 40-60 liters per person. Moreover, with the improvement of living standards and the acceleration of the pace of life, when considering the overall storage of refrigerators, it is necessary to adapt to the choice of refrigerators with larger freezing chambers. In addition, the large-capacity refrigerator takes up more space and consumes more electricity, so when choosing it, we must proceed from our own actual situation and don't blindly pursue large capacity, resulting in unnecessary waste.
(2) Selection of refrigerator type
At present, there are two main types of refrigerators in the domestic market. One is the refrigeration refrigerator, and its defrosting method is generally automatic defrosting in the refrigerating room and manual defrosting in the freezing room. The other is an indirect refrigerator, also known as a frost-free refrigerator, whose defrosting method is fully automatic.
Because the refrigerator is directly cooled, it is fast and energy-saving. Moreover, the freezing room and the refrigerating room are impassable to avoid food odor.
There is only one evaporator in the frost-free refrigerator, and a small electric fan is used to blow the cold air from the freezing chamber to the refrigerating chamber to distribute the cold air, so the temperature distribution in each room is even, and the temperatures of the freezing chamber and the refrigerating chamber can be adjusted separately, and the frost-free refrigerator can be automatically defrosted, but the freezing speed of the frost-free refrigerator is slow and the refrigerator saves electricity.
From the perspective of energy saving, refrigeration refrigerator is more suitable for China's national conditions. Because on the one hand, China is short of electricity, on the other hand, refrigeration refrigerators save more electricity than indirect refrigerators.
In addition to the capacity and type of refrigerator, we should also consider the function, color and manufacturer. In addition, major domestic refrigerator manufacturers are gradually promoting green refrigerators, that is, R 134a is gradually replacing R600, which is also an important factor that cannot be ignored when purchasing.
The choice of refrigerator (2)
Let's introduce the selection of refrigerator (1). I don't know if you have seen it, but now I will continue to introduce the selection of refrigerator to you.
Selection method of refrigerator
The choice of refrigerator can be made in two steps: (1) check before power on; (2) Power-on test.
(a) check before electrifying
1. Visual inspection
After opening the packing box, first check whether the box, door and top frame of the refrigerator are bumped or damaged. Because the refrigerator is heavy and bulky, special attention should be paid to whether there is bottom deformation caused by excessive force during transportation and loading and unloading.
The improved quality of refrigerator surface coating should be uniform and shiny, and there should be no pockmarks, bubbles and obvious scratches, and no large or small areas of coating falling off. The electroplating part of the refrigerator should be bright and delicate, and there should be no coating shedding and embroidery. In addition, attention should also be paid to whether the plastic decorative parts, especially the corners, are damaged.
Both the box and the refrigerator are treated by foaming process. If the technical requirements are not strict or the operation is not careful in the cold storage process, the foaming material on the surface or external coating of the box can be removed, and attention should be paid to whether there is oil stain on the surface of the box when choosing the appearance.
Step 2 check the inside of the refrigerator
First, check the door seal, because the door seal directly depends on the power consumption and insulation effect of the refrigerator, and also affects the life of the refrigeration compressor. A good quality door seal has good suction, and obviously feels resistance when opening the refrigerator door. If not, the quality of the door seal is not good.
The freezer of a refrigerator is generally made of aluminum plate. Check the aluminum plate of the freezer for obvious cracks, because the refrigerator liner is made of ABS plastic plate through vacuum forming process. Check whether there are cracks and wrinkles, especially whether the excessive original angle is smooth and whether the thickness of the plating plate in the inner tank is uniform.
Selection of Refrigerator (3)
Method of power-on inspection;
After the above inspection, you can power on the test run, adjust the thermostat knob to a certain position, turn on the power supply, and check whether the light switch and bulb are normal.
At the moment of turning on the power supply, pay attention to the starting performance of the compressor and whether it can be started at one time.
After the refrigerator runs for a few minutes, touching the condenser of the refrigerator with your hand should have obvious heat sensation, and the sooner you heat it, the better, while the air return pipe has obvious cold sensation. If there is no cold feeling, it means that the performance of the refrigerator is poor. If there is frost in return pipe, it means that there is too much refrigeration, and there is no accumulation of large power consumption, so the refrigeration effect is not very good.
After running for 20-30 minutes, check that there should be a thin and uniform frost layer on the evaporator surface inside the refrigerator. If the frost on the evaporator is uneven or there is no frost on a certain part, it means that the refrigeration performance of the refrigerator is poor. For a cold refrigerator, press the fan switch by hand and the air will be discharged from the air outlet.
Noise is also one of the characteristics of refrigerators. However, when shopping in the store, it is difficult to hear the noise of the refrigerator because of the loud environmental noise, and only the low fan rotation can be heard around. If you touch the box with your hand, you will feel a slight vibration. Because most compressors are quiet. The noise of refrigerator mainly comes from the vibration of compressor, pipeline and box.
How to choose a refrigerator? Don't just listen to the salesman when buying a refrigerator now, choose the refrigerator that really belongs to you and suits you. That's the most economical choice.
