Refrigerator is a tool to keep food fresh. Different foods need different storage temperatures. The temperature of the refrigerator should be set according to the type of food stored, and the set temperature has nothing to do with the season. Generally speaking, green leafy vegetables need 12 degrees, tropical fruits need 10 degrees, cooked food needs 8 degrees, beer drinks need 4 degrees, fresh meat needs-18 degrees, and fish and shrimp need 0 degrees. Generally, when the temperature difference between winter and summer is large, it is necessary to adjust the temperature of the refrigerator at home, so as to save electricity and ensure the quality of food freezing. It should be noted that when adjusting the temperature of the refrigerator, it should not be adjusted at will, which may easily lead to the refrigerator not cooling or various failures.
