First, the choice of refrigerator capacity and form

(1) Capacity of the refrigerator

At present, single-door refrigerators have been eliminated by the market. The refrigerators of about 200 liters are generally only used for single use. The 500-600 liter refrigerators on the market are growing, and the volume of the freezer compartments will also increase. In China's current national refrigerator standard, the volume of the refrigerator is expressed in terms of effective volume. The so-called effective volume refers to the volume of the inside of the refrigerator that can actually be used to store food.

The volume of the choice refrigerator is generally considered to be 40-60 liters per person. And with the improvement of living standards and the pace of life, when considering the overall storage of the refrigerator, it should be adapted to choose a larger refrigerator in the freezer. In addition, large-capacity refrigerators take up a lot of space and consume more power. Therefore, when choosing, you must start from your own 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 direct-cooling type refrigerator, and the defrosting method is generally automatic defrosting in a refrigerating room, and the chilling room is an artificial defrosting. The other is an air-cooled refrigerator, also known as a frost-free refrigerator, whose defrosting method is fully automatic.

In addition to considering the capacity and type, refrigerators should also consider factors such as price, function, color and manufacturer.

Second, the method of selecting the refrigerator

(1) Visual inspection

The surface coating of the refrigerator should be uniform and bright, and there should be no pitting. Bubbles and obvious scratches should not have large and small areas of coating peeling. The plating parts of the refrigerator should be bright and fine, and there should be no peeling or embedding.

The inside of the refrigerator and the inside of the refrigerator are processed by a foaming process. If the process requirements are not strict or the operation is not careful during the refrigeration process, it is difficult for the foaming material to overflow the surface of the casing or the outer coating. Remove, when selecting the appearance, pay attention to the oil surface on the surface of the box.

(2) Internal inspection

First check the door seal first, because the door seal is directly looking at the power consumption and insulation effect of the refrigerator, and it affects the life of the refrigeration compressor. Good quality door seals have a good suction force, and when you open the refrigerator door, you obviously feel resistance. If not, the quality of the door seal is not good.

The freezer compartment of the refrigerator is generally made of aluminum plate. The aluminum plate of the freezer compartment is inspected for obvious cracks, because the refrigerator interior chamber is made of ABS plastic plate through vacuum forming process. Check for cracks and wrinkles, especially if the transition fillet is smooth and the liner is thin and even.

(3) Power check

The power can be tested and the thermostat knob can be adjusted to a certain position to connect the power supply and check whether the light switch and the light 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 one time.

After running the refrigerator for a few minutes, touch the condenser of the refrigerator by hand, there should be obvious thermal sensation, and the faster the heat, the better, and the return air tube has obvious cold feeling. If there is no cold feeling, the performance of the refrigerator is relatively poor. Noise is also one of the main features of the refrigerator. However, when shopping in the store, due to the relatively large ambient noise, it is difficult to hear the noise of the refrigerator, and only the surrounding fan sound can be heard around. If you touch the case with your hand, there is a slight vibration. Because most of the compressor's own noise is not large. The noise of the refrigerator mainly comes from the resonance generated by the pipeline and the tank when the compressor is running.
