Six-door refrigerators generally consume more electricity than four-door refrigerators, which is about 10% higher than four-door refrigerators. Six-door refrigerators generally consume more electricity than four-door refrigerators because they have more refrigerator doors and freezers and need more energy to maintain the temperature in the refrigerator. This will make their power consumption higher. Specifically, how much the electricity cost of a six-door refrigerator is more than that of a four-door refrigerator depends on many factors, such as the size of the refrigerator, the size and power of the freezer, etc. In general, the electricity charge of a six-door refrigerator is about 10% higher than that of a four-door refrigerator, but if the size of the six-door refrigerator is larger, the difference in electricity charges may be even greater.
