1, capacity
The larger the capacity, the larger the space and the better the refrigeration effect. At present, refrigerators are basically multi-door refrigerating rooms, which are generally around 500L, and there are many freezing rooms, which are generally around1200 L. Before buying a box, you must look at your family's income needs and living habits. If you have children at home, try not to buy more than one refrigerator.
2. Capacity size
With the improvement of people's living standards, higher requirements will be put forward for the capacity of refrigerators. For refrigerators, it is generally based on the size of the volume to buy. Generally, the larger the capacity, the better. Subject to capacity. For example, refrigerators with a capacity of 200 liters and 50 liters are much larger than refrigerators with a capacity of 50 liters or 60 liters. For the elderly and children at home, such a refrigerator with larger capacity can give them better choices and guarantees in storing food. Of course, the capacity of the refrigerator depends on the number of family members. Nowadays, most refrigerators use refrigeration technology and refrigeration methods with large refrigerant capacity, so the capacity selection should be based on the number of family members.
3. Price
The price factor is of great concern to everyone. The price difference between two-door and single-door is very big. At present, domestic refrigerators, especially some high-end refrigerators, all use double-door machines. Although the refrigerator is more expensive, its performance is not bad because of its low configuration. Single-door machine is relatively low in structural characteristics and cost performance. Now the second door machine is produced and sold in China because of its low price and high cost performance. Therefore, the average family chooses the second door machine.
4. Noise
The noise of refrigerator refers to the refrigeration noise of refrigerator. Generally speaking, the noise of a single-door refrigerator is higher than that of a double-door refrigerator, because the single-door refrigerator needs to be placed at a higher position from the ground, so the structure of the double-door refrigerator is more complicated and the noise is higher during operation; In addition, both the damper and the silent compressor of the single-door refrigerator emit relatively large volume during operation. The refrigerator itself has a certain power consumption, so when buying a household refrigerator, you must pay attention to its power consumption and try not to choose a high-power refrigerator. Of course, don't buy a small-capacity refrigerator, which saves electricity and electricity. In fact, it's good to buy refrigerators with large capacity as far as possible.
5. Refrigeration mode
In terms of refrigeration methods, it can be divided into direct cooling and air cooling. Direct cooling: the cold air in the freezer is directly transported to the center of food, so the temperature fluctuation is small and it is not easy to freeze. Direct-cooling refrigerator can also store food in three areas, which can keep the original flavor and freshness of food to the maximum extent. However, the disadvantages of direct-cooling refrigerator are that food stinks easily and the food frozen in the cold storage area tastes bad. Air-cooled refrigerator: the air blown out by the fan is directly transported to the food center, so that the ingredients in the refrigerator are always at a low temperature. Generally, the service life of direct-cooling refrigerator is shorter than that of direct-cooling refrigerator, and the price is higher than that of direct-cooling refrigerator.
