RV Fridge / Household Fridge

I may be missing something but every house unit I checked that were in RVs consumed more power for the same size. The ratings are on a label inside the door. Probably the best number would be KW per year. However, you can bet the #s are probably based on a house unit sitting in a 70 degree house.

Power consumption, at least the maximum power consumption as written on the label, is quite possibly higher. The energy usage is undoubtedly less. (This would be measured in kWh per year or month or whatever.)

Keep in mind that power and energy are two different things. Power is the rate of energy transfer (usage or generation). A 100W light bulb that's on for ten minutes a day will use less energy than a 1W light bulb that burns all the time, even though its power usage (when lit) is much higher.

Simply stated, a modern compressor fridge uses a lot less energy to move heat from the cold compartment to the environment than does an RV absorption fridge. While the exact energy consumption in an RV might not exactly correlate with a "standard" house, the relative efficiency differences remain.
