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. The quality of well-known brands is very good, the refrigerator manufacturing technology is reliable, foaming machine has high precision and good raw materials for foaming, 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, the volume of the refrigerator needed by one person in the family is 60-70 liters. Therefore, the refrigerator with an effective volume of 180-300 liters can fully meet the needs of ordinary families.
4. Look at after-sales service: Generally, refrigerators will have a certain repair rate, so it is necessary to choose products with good after-sales service. It is advisable to measure the after-sales service level of the manufacturer from the real factors such as maintenance cost, warranty time limit, maintenance speed, comprehensiveness and thoughtfulness of maintenance service. Generally speaking, under the same conditions, after-sales service, domestic products are more reassuring than imported products and local products than foreign products.
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 above the freezing chamber saves electricity by10 ~15% compared with the double-door refrigerator. The energy-saving refrigerator helps the family to save electricity and money, and also reduces carbon dioxide emissions.
Matters needing attention in refrigerator use
It should be noted that domestic refrigerators and freezers cannot store medicines and vaccines: because the storage of medicines and vaccines requires strict temperature, domestic refrigerators are affected by the environmental temperature and the amount of food stored, and the temperature in the box sometimes fluctuates greatly, which cannot meet the temperature requirements for the storage of medicines.
It should be noted that food will deteriorate if it is stored in refrigerators and freezers for a long time: refrigerators use the method of lowering the temperature to inhibit the reproduction of microorganisms in food, and the catalysis of enzymes will reduce the oxidation speed of food, but low temperature cannot 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 with the extension of storage time, food will also deteriorate. Therefore, the food stored in the refrigerator should not exceed the food storage period.
