how much electricity used by refrigerator?
17245
Domestic fridge power consumption is typically between 100 and 250 watts. Over a full day, a fridge is likely to use between 1 to 2 kilowatt-hours (kWh). This translates into a running cost of about $150 per year per fridge.

A standard residential refrigerator connects to a common household outlet. The outlet provides 110 volts of electricity to power the appliance. Most building codes require the refrigerator connect to a dedicated circuit. This means a circuit breaker in the breaker box only powers that appliance and nothing else.

For a 1200-watt model and a load time of one hour, you use 1.2 kilowatt-hours (kWh), which is about 12 cents per load on a 10 cent per kWh electricity plan. If you run the appliance five days a week, you'll end up paying just $2.40 each month for basic electricity consumption.

In 2014, an electrified Indian household consumed about 90 units (kWh) of electricity per month on an average; enough to run four tube-lights, four ceiling fans, a television, a small refrigerator, and small kitchen appliances with typical usage hours and efficiency levels in India.

For example, if you want a generator to run a refrigerator and a freezer, the wattage (table 2) of the refrigerator would be 800 and the freezer would be 1,000. To select the correct size generator, you decide if both refrigerator and freezer are to start at the same time. If so, you would need (1,800 X 4) 7,200 watts.

Refrigerator temperatures range from 2° To 7°C (36° to 45°F); freezer temperatures from -26° to 0°C (-15° to 32°F). Some models are available in either 120 volts/60 Hz or 240 volts/50 Hz.

To continuously run the unit, you need approximately 800 watts. However when the compressor kicks in, it requires a the additional 1200 surge watts. So it takes 2000 watts to supply ongoing power to your refrigerator/freezer.

Watts are the power - what is needed to run a device. Amperage/current is how fast it flows and voltage is like the supply. By the data provided, it appears that the DC fridge requires less power to run than the AC fridge. The power consumed by the same device is the same, just the voltage and amperage changes.

Overall, the national average is two gallons per kWh of electricity consumed. The evaporative cooler runs on 450 watts; a three ton conventional unit uses ten times that, consuming running at 4500 watts, or about 4 kWh every hour more if running constantly. That production consumes 8 gallons of water on average.

The study showed that the typical evaporative cooler consumed about 1500 kilowatt-hours of electricity per summer, costing about $150 at current rates. The cooler's water consumption added an average of $54 to a municipal water bill over the course of the summer, for an electricity-and-water total of $204 per year.

An energy-efficient large freezer with more than 25 cubic feet will use about 956 kilowatt-hours per year, according to EnergyStar.gov. That equates to about $10 a month. When you reduce the size of your freezer, your costs go down. Standard freezer sizes run between 19 cubic feet and 22 cubic feet.

Though more expensive, it consumes much less power.” An old 1.5 tonne AC uses around 1.5 units per hour, while an inverter AC uses only 0.91 units per hour. A refrigerator accounts for 15% of a household's total power consumption. ... Big fridges and ones with features like instant ice maker use more energy.
