Freezing in the freezer will lead to the decrease of refrigeration effect, because the refrigeration principle of the refrigerator is that the refrigerant passes through the conduit in the freezer and is repeatedly compressed and gasified to take the heat in the refrigerator out of the refrigerator. If there is ice on the inner wall of the refrigerator, it will inevitably lead to the decrease of refrigeration effect, and then increase the energy consumption of the compressor, so it is necessary to clean the accumulated ice in the refrigerator regularly.

Unplug the power supply, clean up the things, and then wipe the water clean when the frost thaws.

My family is like this, except1-once every two months.
