The electric usage of a domestic fridge or a refrigerator depends upon various factors.
Fridge power consumption per day.
For example if the annual kwh rating is 875 kwh divided by 365 days will give you about 2 4 kwh per day which means the average wattage accounting for all factors is about 100 watts.
Typically the refrigerator s power consumption in between 100 to 250 watt w.
Now let s assume that the compressor uses 4 amps of power at 12v.
This translates to 33 kwh 50 kwh per month or an average wattage of 46 to 69 watts this equates to an average hourly power consumption of 46 to 69 wh.
Now if you are in a warm environment you can say that the refrigerator will effectively work for around 8 hours.
Domestic fridge power consumption is typically between 100 and 250 watts.
Energy usage rates vary across the country but typically around 13 per cent of your energy bill is likely to be attributed to running your fridge.
For a typical modern 15 cu.
The letters na denote appliances that would normally be powered by non electric sources in a pv powered home.
This translates into a running cost of about 150 per year per fridge.
The electricity usage of the fridge is between 1 2 kwh kilowatt hour or units per day but as i say it may vary due to various factors.
The average energy usage of modern refrigerators is 400 600 kwh per year.
The power company will charge you per kilowatt hour kwh.
Over a full day a fridge is likely to use between 1 to 2 kilowatt hours kwh.
The average wattage of the refrigerator 2 3 kwh 2300 watts per day.
A modern freezer will use between 30 and 100 watts of power depending on size indoor temperature efficiency.
Annual power consumption 700 kwh.
The power consumption of refrigerators is 400 1 000 kwh per year this applies to models in the 21 25 cubic foot range.
But if you re running two or more fridges the potential savings start to become obvious.
That is the power used for a period time.
If the company charges 20 cents per kwh then that 100w globe costs you 20 cents to run for 10 hours 10 cents for 5 hours etc.
So the 100w rated globe above needs to run for 10 hours to use 1kw of power.
Multiply 48 watts with 8 hours and you will get roughly 384 of watt hours per day.
Number of days used 300.
How to identify an energy efficient refrigerator.
Where a range of numbers is given the lower figure often denotes a technologically newer and more efficient model.
Freezer about 300 kwh is used annually or an average of 35 watts this power consumption is already factoring compressor cycles and yearly temperature changes in the northern hemisphere.
A 300 watt item used for 5 minutes per day will only consume 25 watt hours per day.
