2, look at the quality of the refrigerator: when buying a refrigerator, carefully observe whether the box of the refrigerator is flat, whether there is depression or deformation. Well-known brands have good quality, reliable refrigerator manufacturing technology, high precision foaming machine and good foaming raw materials, so the quality of such products is excellent.
3, look at the volume: the volume of the refrigerator should be selected according to the actual needs of the family. Generally speaking, a household needs a refrigerator with a capacity of 60-70 liters. Therefore, 180-300 liters effective volume refrigerator can fully meet the needs of ordinary families.
4. Look at after-sales service: Generally, refrigerators will have a certain repair rate, so choose products with good after-sales service. It is advisable to measure the after-sales service level of the manufacturer from the realistic factors such as maintenance cost, warranty period, maintenance speed, comprehensiveness and thoughtfulness of maintenance service. Generally speaking, under the same conditions, after-sales service, domestic goods are more assured than imported goods, and domestic goods are more assured than foreign goods.
5. Choose an energy-saving refrigerator: The energy-saving refrigerator has stronger thermal insulation performance and consumes less electricity than other refrigerators, so try to choose an energy-saving refrigerator when purchasing a refrigerator. Moreover, the refrigerator on the freezing chamber saves electricity 10 ~ 15% compared with the double-door refrigerator. Energy-saving refrigerators help to save electricity and money at home, and also reduce carbon dioxide emissions.
Matters needing attention in refrigerator use
It should be noted that domestic refrigerators and freezers cannot store drugs and vaccines: because the storage of drugs and vaccines requires strict temperatures, the temperature in the refrigerator sometimes fluctuates greatly due to the influence of environmental temperature and the amount of food stored, which cannot meet the temperature requirements for drug storage.
It should be noted that foods stored in refrigerators and freezers for a long time will deteriorate: the refrigerator uses the method of lowering the temperature to inhibit the reproduction of microorganisms in food, and the catalysis of enzymes will slow down the oxidation speed of food, but low temperature can not completely kill microorganisms and prevent the catalysis of enzymes and food oxidation. Many microorganisms can grow slowly in a low temperature environment below 0℃, and food will deteriorate with the extension of storage time. Therefore, the food stored in the refrigerator should not exceed the shelf life of food.
