The power consumption of refrigerators is 400 1 000 kwh per year this applies to models in the 21 25 cubic foot range.
Fridge power consumption per day.
The average wattage of the refrigerator 2 3 kwh 2300 watts per day.
Multiply 48 watts with 8 hours and you will get roughly 384 of watt hours per day.
But if you re running two or more fridges the potential savings start to become obvious.
Of course this is unavoidable as fridges must be run 24 hours per day to keep food fresh.
Over a full day a fridge is likely to use between 1 to 2 kilowatt hours kwh.
Now let s assume that the compressor uses 4 amps of power at 12v.
How to identify an energy efficient refrigerator.
Number of days used 300.
That is the power used for a period time.
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.
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.
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.
Where a range of numbers is given the lower figure often denotes a technologically newer and more efficient model.
The letters na denote appliances that would normally be powered by non electric sources in a pv powered home.
Multiply 4 amps with 12 volts and you will get 48 watts.
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.
Typically the refrigerator s power consumption in between 100 to 250 watt w.
So the 100w rated globe above needs to run for 10 hours to use 1kw of power.
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.
This translates into a running cost of about 150 per year per fridge.
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.
The power company will charge you per kilowatt hour kwh.
Click calculate to find the energy consumption of a refrigerator using 180 watts for 24 hours a day 0 10 per kwh.
Now if you are in a warm environment you can say that the refrigerator will effectively work for around 8 hours.
The average energy usage of modern refrigerators is 400 600 kwh per year.
For a typical modern 15 cu.
Annual power consumption 700 kwh.
Domestic fridge power consumption is typically between 100 and 250 watts.
