How many watts is a fridge compressor?
The identification tag on the compressor should specify the power that it draws in watts. A typical refrigerator draws 725 watts, according to the United States Department of Energy. Divide that number by 120 volts, which is the voltage of your power supply, to get the current that the refrigerator draws in amperes.
How do you calculate energy consumption of a refrigerator?
To get the kWh/24h figure, we only need to divide the wattage by 1,000 then multiply by 24 hours. So if the wattage of the refrigerator here is rated at 71 W, it follows that its energy consumption should be at 1.704 kWh/24h.
How many units of electricity does a refrigerator use per hour?
Hence daily power consumption of my refrigerator is – 38.33 kWh / 30 – 1.278 kWh of electricity. In terms of electricity bill it translates to Rs 12.
What is the formula for power consumed?
Hence, the energy consumption formula or the power consumption formula is given as below: E = P*(t/1000); where E = energy measured in Joules or in kilowatt-hours (kWh), P = power units in watts, and t = time over which the power or energy was consumed.
How do I calculate freezer wattage?
To determine the average wattage for your refrigerator, you need to multiply volts x amps for your wattage calculator. You will find these numbers referenced on a sticker on the inside wall of the fridge, the manufacturer’s nameplate below the door, behind the front kick plate, or on the back of the fridge.
How many amps does a refrigerator compressor draw?
Refrigerator amps are the amount of electrical current it’s compressor uses to cool it’s compartment. Amperage for most household refrigerators, is anywhere from 3 to 5 if the voltage is 120. A 15 to 20 amp dedicated circuit is required because the in-rush amperage is much higher.
How much electricity does a refrigerator?
Conventional refrigerators typically have a starting wattage of 800-1200 watt-hours/day, and a running wattage of around 150-watt hours/day. Refrigerators are reactive devices that require additional power to start because they contain an electric motor, but significantly fewer watts to run as they remain on.
What is power consumption of refrigerator?
Factors That Determine Electricity Consumption Of A Fridge
| Size Of Refrigerator | Monthly Power Consumption |
|---|---|
| 200 Litres | 60 kWh |
| 300 Litres | 75 kWh |
| 400 Litres | 90 kWh |
| 500 Litres | 120 kWh |
How much electricity does a fridge use in a month?
Appliance Energy Use Chart
| Detail | Estimated Energy Usage* |
|---|---|
| Refrigerator (frost-free), 15 cu. ft. (1996 unit) | 150 kWh per month |
| Freezer (manual defrost), 15 cu. ft. | 90 kWh per month |
| Newer Units – ENERGY STAR Refrigerators | |
| ENERGY STAR Refrigerator, 14 cu. ft. | 34.5 kWh per month |
How much amps does a refrigerator use?
Generally, a fridge uses about 6 or 7 amps, but triple that for the start-up surge, Accordingly a dyed-in-the-wool authority pipe with 15 to 20 amps is compulsory for a fridge. It must be the sole piece of equipment plugged into that outlet.
