1. Replace the sealing ring: the sealing ring on the newly bought refrigerator door is tight. After closing the refrigerator door, the air conditioner does not run out, which is quite energy-saving. After the refrigerator has been used for a period of time, the sealing ring is loose and the closure is not tight. A new sealing ring can be replaced to help save electricity.

2. Slimming the refrigerator: If the food we bought that day is not meat and we have to put it in the refrigerator, then don't put it in the refrigerator. Like vegetables, eat them on the same day and put them outside. It doesn't work in the refrigerator and consumes electricity.

Don't put hot food in the refrigerator: everyone likes to drink ice water in summer. Some people put hot water cups in the refrigerator in order to cool down quickly. This is a very power-consuming practice, and it will also affect the life of the refrigerator. Wait for the water temperature to cool naturally before putting it in the refrigerator.

4. Ice water into a bowl of ice cubes: use a small bowl filled with cold water. Put the bowl in the refrigerator again and wait for the cold water to freeze. Note that it is cold water and ice, not hot water. And don't use cups. The cup is not as big as a bowl and can't hold much water.

5. Put the ice bowl into the freezer: after the water ice in the bowl becomes ice cubes, take the bowl into the freezer. This reduces the temperature of the refrigerator, saves electricity and makes the temperature of the refrigerator lower.

6. Replace the ice water in time: If the ice water in the bowl is left in the refrigerator for a long time, it will slowly melt. It just melts a little slower than outside. After the ice melts, put a bowl of ice into the freezer again to cool down.
