In general, you should know the volume of the refrigerator before buying it. For example, small refrigerator: the total volume is below 60 liters, and the size is 515x500x530 mm; ; Opposite-door refrigerator: the total volume is above100L, the size is about 900x590x 1750mm, and some are smaller; Common double-door refrigerator: the total volume of the refrigerator with the upper and lower doors is 100-200 liters, and the general size is about 1600x495x635mm. Usually, the refrigerator for personal use is 70L-80L, and that for a family of three is 2 10L-240L.

2. Function

With the development of the times, refrigerators with the functions of air cooling, frost-free, ion sterilization, photosynthetic preservation, soft freezing and ECO energy saving have been listed. However, for us ordinary people, we should pay attention to whether these functions of the refrigerator are practical for us. Generally speaking, most families need fresh-keeping and quick-freezing, so we don't need to spend too much money to buy a complicated refrigerator.

3. Energy consumption

I believe everyone knows that refrigerators are big consumers of electricity, so there will be a fixed electricity bill every month. When we choose a refrigerator, we need to know the power consumption of the refrigerator. If its parameters exceed 1, it means that its daily power consumption has exceeded 1 degree. At this time, the electricity bill is also an amazing number!
