The refrigerator is made by Siemens, but Haier is a good choice if it is made in China!

The price is not important!

A few days ago, relevant industry insiders pointed out that there is a lot of unrealistic propaganda about refrigerators in the market. Almost all kinds of refrigerators are labeled as "green refrigerators", "environmentally friendly refrigerators", "fluorine-free refrigerators", " Names such as "Energy-saving Refrigerator" can easily lead consumers into misunderstandings. For this reason, the industry pointed out that the following issues deserve consumers' attention:

The degree of freezing should be practical.

The freezing power is an important technical indicator for measuring refrigeration equipment. However, refrigeration appliances are used for different purposes. Compared with special needs such as 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 needlessly, but also destroy the internal tissue and nutritional structure of food. For those who pay attention to color, fragrance, and freshness, preservation is the first need for consumers when buying a refrigerator.

Expensive may not mean advanced

The pursuit of famous brands is today’s consumer fashion. But famous brands do not mean high prices, especially for products with mature technology such as refrigerators. Different brands have basically the same raw materials, manufacturing processes, and quality performance, so the manufacturing costs are also roughly the same. The factors that affect product prices are often soft costs, such as advertising expenses, internal management expenses and other factors. In particular, the management level of the company and the use of marketing strategies play a very important role in commodity prices.

Refrigerators are not "the more energy-saving, the better"

Like freezing power, the power consumption of a refrigerator is also a very important performance indicator. But to achieve the best preservation effect, it is not enough to just reduce electricity consumption. Optimized structure and refrigeration design are necessary.

Enterprises can achieve the purpose of saving electricity through simple measures such as adding insulation layers (the cost will increase accordingly), or they can also improve energy efficiency ratio by adopting new technological achievements. Therefore, we cannot one-sidedly emphasize "saving electricity more". The better”

Purchase of Refrigerator (1)

Nowadays, families are busy buying some home appliances when they get married or buy a new house; How much can you understand when you? I will now tell you how to choose a refrigerator, so that you can choose a refrigerator that is suitable for your family and is economical and affordable.

1. Selection of refrigerator capacity and form

(1) Refrigerator capacity

Since 1914, the American Calvinette Company first produced the first refrigerator. Since a refrigerator was put on the market, the capacity of the refrigerator has been developing towards large capacity. At present, single-door refrigerators have been eliminated from the market. Refrigerators of about 200 liters are generally only used by single people. The market of 500-600 liter refrigerators continues to grow. At the same time, the freezer compartment volume will also increase.

In my country's current national refrigerator standards, the volume of refrigerators is expressed in terms of effective volume. The so-called effective volume refers to the volume inside the refrigerator that can actually be used to store food.

When choosing a refrigerator, the capacity is generally 40-60 liters per person. And with the improvement of living standards and the acceleration of the pace of life, when considering the overall storage of the refrigerator, you should adapt to choosing a refrigerator with a larger freezer compartment. In addition, large-capacity refrigerators take up more space and consume more power. Therefore, when choosing, you must proceed from your actual situation and do not blindly pursue large capacity and cause unnecessary waste.

(2) Refrigerator type selection

At present, there are two main types of refrigerators in the domestic market. One is a refrigeration refrigerator, and its defrosting method is generally automatic defrost in the refrigerator compartment. The freezer is manually defrosted. The other is an intercooling refrigerator, also called a frost-free refrigerator, whose defrosting method is fully automatic.

Since the refrigeration refrigerator uses direct cooling, it has fast cooling speed and saves energy. Moreover, the freezer and refrigerator compartments are blocked to avoid food odor transfer.

A frost-free refrigerator has only one evaporator. It uses a small electric fan to blow the cold air from the freezer to the refrigerator to distribute the cold air, so the temperature in each room is evenly distributed, and the temperatures in the freezer and refrigerator can be adjusted separately. And it can defrost automatically, but the freezing speed of frost-free refrigerator is relatively slow, and the refrigerator saves electricity.

From an energy-saving perspective, refrigeration refrigerators are more suitable for my country’s national conditions. Because on the one hand, my country's electricity supply is relatively tight, and on the other hand, refrigeration refrigerators save more energy than indirect cooling refrigerators.

In addition to considering capacity and type of refrigerator, factors such as function, color and manufacturer should also be considered. In addition, major refrigerator manufacturers in my country are currently gradually promoting green and environmentally friendly refrigerators, that is, gradually replacing R600 with R134a. This is also an important factor that cannot be ignored when purchasing.

Purchasing of Refrigerator (2)

We introduce the selection of Refrigerator (1). I don’t know if you have read it. Now I will continue to introduce to you the selection of Refrigerator. purchase.

How to select a refrigerator

The selection of a refrigerator can be carried out in two steps, (1) inspection before power on (2) power on test

(1) Inspection before powering on

1. Appearance inspection

After opening the packaging box, you should first check whether there are any bruises or damage to the refrigerator box, door and top frame. at. Since the refrigerator is heavy and relatively large, special attention should be paid to whether there is any bottom deformation caused by excessive force during transportation, loading and unloading.

The surface coating of the refrigerator should be uniformly shiny, without pitting, bubbles and obvious scratches, and there should be no large or small area coating peeling off. The electroplated parts of the refrigerator should be bright and fine, and there should be no peeling or embroidery of the coating. Also pay attention to plastic trim, especially around corners, for damage.

The refrigerator box and the inside of the refrigerator are processed through the foaming process. If the process requirements are not strict or the operation is not careful during the refrigeration process, the foaming material will come out of the box or The external coating surface can be easily removed. When selecting the appearance, you should pay attention to whether there are any oil stains on the surface of the box.

2. Inspection of the inside of the refrigerator

First check the door seal, because the door seal directly affects 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 adhesion. When opening the refrigerator door, you will obviously feel resistance. If not, the door seal is of poor quality.

The freezer compartment of the refrigerator is generally made of aluminum plates. Check the aluminum plates of the freezer compartment for obvious cracks, because the refrigerator refrigeration chamber is made of ABS plastic plates through a vacuum forming process. become. Check whether there are any cracks or wrinkles, especially whether the excessive original corners are rounded, and whether the thickness of the liner plate is even.

Methods for power-on inspection;

After the above inspection, you can power on for trial operation and adjust the thermostat knob. Go to a certain location, connect the power supply, and check whether the light switch and bulb are normal.

At the moment when the power is turned on, attention should be paid to the starting performance of the compressor and whether it can be started at once.

After the refrigerator has been running for a few minutes, if you touch the condenser of the refrigerator with your hand, there should be an obvious feeling of heat, and the faster it heats up, the better, while the return pipe should have an obvious feeling of coldness. If there is no cold feeling, it means that the performance of the refrigerator is relatively poor. If there is frost on the return pipe, it means too much cooling is added, which consumes a lot of electricity and the cooling effect is not very good.

After running for 20-30 minutes, check that there should be a thin and even layer of frost on the surface of the evaporator inside the refrigerator. If the frost on the evaporator is uneven or there is no frost on a certain part, it means that the cooling performance of the refrigerator is relatively poor. For intercooling refrigerators, press the fan switch with your hand, and cold air will come out from the air outlet.

Noise is also one of the main features of refrigerators. However, when purchasing in the store, due to the relatively loud ambient noise, it is difficult to hear the noise of the refrigerator. Only the low sound of the fan rotating can be heard in the surroundings. If you touch the box with your hands, you will feel a slight vibration. Because most compressors themselves are not very noisy.

Refrigerator noise mainly comes from the vibration generated by the compressor and the pipes and box when it is running.

That’s it for you on how to choose a refrigerator. When buying a refrigerator now, don't just listen to what the salesperson says, you have to choose a refrigerator that truly suits you. That is the most economical and affordable option.
