Can the wattage of a refrigerator fluctuate?
Yes, the wattage of a refrigerator can fluctuate. Due to the nature of refrigerator operation, the power consumption is not constant. The most energy-efficient refrigerators have compressors that run on a variable speed, meaning they consume more power when the compressor is activated to start the cooling process and drop it down once the unit reaches set temperatures.
Over time, the refrigeration system also accumulates frost on the evaporator coils, which can temporarily increase the power consumption as the defrost cycle is activated to melt the frost. The thermostat and other components within the refrigerator also regulate the refrigeration system’s operation to optimize efficiency and ensure proper cooling performance. This results in a fluctuation in the wattage of the refrigerator as the different components activate and de-activate.
According to the U.S. Department of Energy, the EnergyGuide label typically shows the “kWh/year” of a refrigerator’s power consumption, rather than the exact power rating in watts. The reason for this is because averaging out the fluctuation of power consumption over a longer period, such as one year, gives consumers a more accurate representation of the appliance’s overall energy usage rather than focusing solely on an inaccurate average wattage rating.
