As the saying goes, it is a truth to spend money on the cutting edge, saving electricity rather than how much electricity is used in the refrigerator marked by the merchant every day. The energy efficiency label on the refrigerator is the electricity used to fill the refrigerator with food at room temperature (about 25℃), but the freezing capacity of each refrigerator is different. For example, a refrigerator of about 220 liters, the domestic 24-hour freezing capacity is only less than 8 kilograms, and most of Siemens' words are more than 8 kilograms. In this case, it is impossible for a household refrigerator to completely freeze all the food in one day, but Siemens can. If the food given to you can't be completely frozen, the food can't be kept fresh, and the electricity bill is 10 cents less, the food is really wasted.
