To understand the difference between 3 star and 5 star ac refrigerator we must first know how it works.
5 star refrigerator power consumption watts.
Wattage use for a mini fridge can be found with the same formula.
Let s check out our electrical appliances power consumption table below.
This translates into a running cost of about 150 per year per fridge.
Then multiply that current with voltage and point eight or point nine 8 or 9 as cos theta which in return will give you exact wattage of the motor.
The average wattage of the refrigerator 2 3 kwh 2300 watts per day.
Don t forget to inspect each appliance power tool in your home individually to see the precise wattage consumption.
Dear you have to make sure how much current it draws.
This will require 126 5 running watts for typical use.
Considering per unit charge of electricity to be approximately rs.
Domestic fridge power consumption is typically between 100 and 250 watts.
1 1a x 115v 126 5 watts.
Wattage voltage x current x cos theta.
Model crf150ss 1 has a rated current of 1 1a running on 115 volts.
Over a full day a fridge is likely to use between 1 to 2 kilowatt hours kwh.
Here are some tips for keeping your mini fridge s compressor from turning on too often and boosting the starting.
As a comparison to chest freezer wattage the otter tail power company notes that an average 16 to 18 cubic foot frost free refrigerator freezer uses 400 watts and a 10 to 15 cubic foot non frost free refrigerator freezer uses 300 watts.
Multiple surveys suggest that people who are aware of the star rating system tend to choose 5 star systems.
Before you think okay great now i know how much power my fridge uses sorry to say but it.
In terms of energy efficiency they are way better than other stars.
The calculation for the above example would be.
Lower wattage models can range between 85 to around 100 watts while running 4 but many mini fridges can go up to 250 watts 5.
2 5 and comparing them with a no star refrigerator that consumes 1100 kwh per year and costs you a bill of rs 2750 yr we get.
The big difference between the 4 star and 5 star refrigerators is the lesser amount of power consumption.
For instance you may see 115 v and 6 5 amps multiplying these two numbers tells you how many watts your refrigerator uses in this case 747 5 watts.
Is more stars actually consume less power consumption and reduce your electricity bill.
How many watts does a mini fridge use.
As noted above there are periods of startup or surge power that typically can be 2 3 times the amount of running watts.
Find the voltage and amperage of the refrigerator.
