It can be tricky for you to calculate the power consumption of refrigerators, given that refrigerators do not continuously use 100% of the energy that is drawn. You should also consider the fact that these will consume power more in hot weather, and less in winter.
You should basically check the compressor’s consumption and the general specifications that your manufacturer gives. Generally, it has the highest specs. As an example, if at 12V your refrigerator compressor uses 4 Amp power, you have to multiply 4 Amp with 12V. This will give you 48 watts. If you live in a warm weather country, you can be assured that the fridge will work effectively for about 8 hours. Multiply 8 hours with 48 watts and you can get around 384 watt-hours every day.
What Are The Amps Actually?
An amp measures the electricity flow rate. The sizes of wire and circuit breaker are determined by electrical codes on the basis of amps. A circuit overload gets the wires overheated and results in a fire hazard. When more than one appliance tends to work on the same circuit, the total amps for every appliance have to add up to less than the wire and circuit breaker rating.
How many amps does a refrigerator use, the answer isn’t quite simple. A standard frost-free, 16-cubic-foot fridge uses 750 watts and consumes 6 amps electricity. In the U.S, the amps are decided by dividing the total number of watts by 120 V. The amps of a particular refrigerator are calculated easily on the basis of the watts that the manufacturer’s label lists.
Refrigerator amps mean the amount of electrical energy used by a refrigerator compressor to cool down the compartment. For most domestic fridges, the amperage ranges between 3 and 5 in case of 120 V. You need a dedicated 15 – 20 amp circuit as the in-rush amperage is significantly more. The average amp is reduced as the compressor is not operating all the while. It is measured often in KWH (kilowatt hours).

Here is a small calculation that must help you to understand:
Amperage equals the unit’s wattage divided by voltage.
To put simply, Amperage = Watts/Voltage.
In the US, voltage is standardized and every home has 120 Voltage. When you consider this fact, any refrigerator of small size having up to 240wattage would fall under the restriction of 2amps that is prevalent in most colleges. Most small fridges are powered by the Energy Star technology, which can reduce the power consumption of a fridge.
How many amps does a refrigerator use, when it comes to domestic refrigerators, the consumption of power is generally in the range of 100 – 200 watts.
Through a whole day, these are likely to consume about 1 – 2 kWh or kilowatt-hours. Old commercial and domestic refrigerators draw more energy.
The Real Consumption Of Energy Is Based On Numerous Factors, Such As:
In case you place the refrigerator in a warm area, such as adjacent to the oven or in an area with poor ventilation, the compressor will have to work much harder.
Generally, bigger sized fridges tend to hog more energy.
In case the door of the refrigerator is held open for long or opened often, the compressor will have to operate harder in order to cool the area. An empty refrigerator will have to work more as compared to one that is well-stocked, given that ‘warm air’ will replace more ‘cool air’ every time you open it door.
Temperature set point
A factory setting might keep your refrigerator cooler in your house than is necessary. For safe storage of foods, keep the temperature in the range of 3 – 5 degrees Celsius. Make sure that your freezer and fridge temperatures are no needlessly cold with such a thermometer.
Generally, older refrigerators have lower energy efficiency as compared to newer refrigerator models.
Look at the seals surrounding the door. In case the seals are worn out, the efficiency will be less.
It is important to get home an Energy Star-rated fridge to reduce the consumption of power by the compressor. You can also control the usage of power in many other ways, such as by being watchful and knowing how to properly use your refrigerator. Do not leave an empty refrigerator running. It will waste energy. The fuller your fridge is, the less the amount of power it consumes. This happens because the things that you keep inside will prevent the escape of cold air when the fridge is opened. Thus, it does not have to operate harder to freeze again.
Older refrigerators also have to be avoided, as these use more amount of power. These do not have the Energy Star technology that saves power. The smaller the size of the fridge, the less the consumption of power would be. Regularly defrosting your refrigerator can keep it proper, operational state and also restrict the usage of power. You can also reduce power consumption by not letting your fridge stand in direct sunlight, reducing how many times the refrigerator is opened and closed and ensuring that it is over a level surface.
Typically, although a refrigerator consumes a lot of energy you are unlikely to spot any difference in your energy bills when you use mini fridges. The operational costs of the average refrigerators are around 10 USD per month. That might not be a big deal for a single home, and family members are unlikely to give much thought to it. But, 5 dollars per room can begin to add up for college dorms with 100 rooms or more. Due to these reasons, colleges have restrictions about the amps that can be used by fridges.
How To Clean Refrigerator- Watch Till The End
How To Clean Refrigerator: Tips & Tricks
How to clean a refrigerator, maybe a very common question but the solution isn’t common. Every now and then, you need to clean a fridge inside out. You have to wash down the shelves to clear spilt milk and throw away any food that is rotted and exceeded its shelf life. Although this is not the most comfortable task, you can save on hassles and time when you know how to do it in a proper way.
Clean You Refrigerator: Tips From Experts!
- Take 1-gallon hot water and make an all-purpose cleaner at home by blending all these ingredients into a bowl:
- Vinegar – ½ cup
- Ammonia – 1 cup, transparent.
- Baking soda – ¼ cup.
Combine all the ingredients and pour the mixture into a spray bottle. Or pour it over to a sponge from a bowl. It is a no-rinse homemade formula that can remove grease, and prevent mildew and mold. Use this solution to wipe the whole fridge down, including the shelves and drawers.
- Get rid of tough stains with toothpaste, which has a nice smell and a soft abrasive.
- Remove lingering bad smell from vegetable bins by placing a crumpled grocery bag made of brown paper inside. Leave it for 2 days. The bad odor would be absorbed by the paper.
- Take the grill off to get rid of all the dust bunnies from beneath the fridge. Pass a yardstick that is covered with two panty hoses. Also look at the water pan under the refrigerator, given that it can contain water that is not pleasant in smell.
- Get a clean old sock. Fill it with activated charcoal, which can be obtained from a local aquarium store. Make a knot at the top of the sock and put it in the fridge’s backside to get rid of household odors. It will last 1 – 2 months, based on how large your fridge is and how often you use the same.
- Put an illuminated flashlight within the fridge and close the door to ensure that the insulating seam is tight enough around the door. Turn the room lights off and find out whether there is the escape of any light from the seams. You should do this during the night to identify any leaks easily.
- Do not keep the fridge full. Have a big bottle, a minimum of 1 gallon, and fill it with water before keeping it inside the refrigerator. It can keep the fridge cool and efficiently operational.
- Try to adjust the suitable temperature of the fridge. The temperature of the fridge nearly 35 to 38 degrees Fahrenheit which means 1.7 to 3.3-degree Celcius.
- Once you have cleaned the fridge, apply some paste wax onto the refrigerator’s top surface, in order to prevent the accumulation of odor and grease.
- If you want to remove odors quickly, get a few cotton balls and sprinkle vanilla extract over them. Put these in a shallow dish and keep inside the fridge. You can also benefit from the orange extract.
Once you have calculated the energy consumption of your fridge in amperage, try to reduce the energy bills as much as possible. Changing to solar power, adjusting the refrigerator to run at a lower level and using propane rather than batteries are some of the ways to lower your refrigerator’s power consumption.
