# single door refrigerator power consumption

Our team has researched and reviewed the Single Door Refrigerator Power Consumption to help you come up with a better decision. We’ve also put up a 5 star refrigerator power consumption shopping guide with the features you can consider when calculating the 5 star refrigerator power consumption watts.

Refrigerators are one of the most common household appliances and are used to preserve food by keeping it cool, most refrigerators also come with a built-in freezer box for freezing food. Modern refrigerators are very energy efficient compared to older models from a few decades ago. A fridge will use anywhere from 100 to 400 watts depending on size, a large fridge will use about 180 watts or 1575 kWh annually.

## Electricity usage of a Refrigerator

This calculator does not account for compressor cycles and other factors which can drastically increase or decrease power usage. You will need to know an average running wattage of your fridge to get an accurate result, if you input the rated wattage you will get a highly inflated result. One way to determine the actual running wattage is to find the daily or annual kWh rating and use that as the baseline for your calculation. 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.

# Single door refrigerator vs double door refrigerator

When you decide to buy new refrigerator, one of the important decision factor is whether to buy single door or double door refrigerator. Let’s compare both the refrigerator models side by side and decide easily. Try our refrigerator selector to choose right refrigerator by answering simple questions without reading any buying guide.

## Single door vs double door refrigerator power consumption

Many readers of Zelect mailed us and asked about power consumption as people gets confused regarding whether will double door refrigerator increase the power consumption or decrease the power consumption. There is a reason for that confusion to occur. Let’s investigate the reasons and facts in detail. The short answer is single door refrigerator consume less power.

First, double door refrigerator works in frost free mode, where electric fans are used to circulate cool air. Apart from that, double door refrigerator comes in large size of 235 to 295 liters capacity. This large size results in more power consumption. It requires around 30 to 40% more power or electricity.

One interesting fact is in the single door refrigerator to open a freezer, first you need to open the refrigerator main door and then freezer door. Because of frequent opening of door the whole fridge temperature goes up. It requires much electricity to cool down once again.

But the additional power consumed in double door refrigerator to cool down is very high compared to the extra power consumed in frequently opening of the main door of single door refrigerator(to open freezer door). Hence single door refrigerator consume less power and can save lot of electricity bill. Even old refrigerator consumes more energy than new refrigerator.

# How Much Power a Fridge Uses – in Watts, Cost & kWh

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.

Before you think “okay great – now I know how much power my fridge uses” – sorry to say, but it’s not quite that simple!

In the following post, I’ll outline how you can gain a complete understanding of your fridge or freezer’s power usage.

## What Affects Fridge Power Use

The actual energy consumption of your fridge or freezer will depend on many factors. These include:

• Type. For example, a commercial display fridge can use ten times more than your bar fridge at home.
• Size. Anything with a larger volume, such as side by side fridges, use more electricity.
• Location. If the fridge is in a warm position, or poorly ventilated, it will use more power.
• Season. All refrigerators use more power in summer than in winter as the ambient temperature is higher.
• Usage. If the fridge door is opened frequently or held open, the compressor will need to work harder to keep things cool. Also, an empty fridge may need to work harder than a reasonably-stocked fridge because more ‘cool air’ is replaced with ‘warm air’ each time the door is opened.
• Temperature set point. The factory setting may keep the fridge cooler than is needed in your home.
• Age. Old refrigerators are usually less energy efficient than new high star rated fridges.
• Condition. If the seals are in poor condition, your fridge will be less efficient.

## So, How Much Power Does a Fridge Use?

For a quick check of fridge wattage, find the compliance plate and make some quick calculations. The compliance plate is usually located inside the fridge.

The fridge compliance plate is a useful first approximation of power usage. In this case, it indicates the fridge uses 130 Watts when on.

For example, for my refrigerator, the numbers are:

• Refrigerator wattage = 130 Watts
• Estimated usage = 8 hours per day (33% duty cycle)
• Total energy = 130W x 8h = 1040Wh = 1.04kWh/day
• Total cost = 1.04kWh/day x 365 days x \$0.25/kWh = \$94.90/year

#### Basic Refrigerator Power Consumption Calculator

To summarise the above calculation, we have:

• Fridge Wattage x Hours Per Day = Watt-hours per day
• Watt-hours / 1000 = kWh per day

The above fridge power consumption calculator is not very accurate because the fridge may not consume its rated wattage. Also, the compliance plate does not account for all the other variables that affect power usage. For example, your fridge may have a fault or other issue causing it to operate for 16 hours per day, not 8. That alone would double its usage!

#### Better Fridge Power Consumption Calculator

To find out the actual wattage of your refrigerator, you need to use a power meter. Our Plug-in Power Meter is the most popular and cheapest option. The Power Mate Lite is our highest accuracy option, often used by professional energy auditors.

Use a plug-in power meter to check your fridge’s power consumption.

These devices have the benefit of measuring rather than estimating. You can plug your fridge in for a full 24 hour period and see how many kWh it uses. More importantly, you can make some changes and see if you can reduce your energy consumption.

#### What About The Fridge Star Rating?

Energy efficiency ‘star ratings’ are a great buying guide. But because of the variable factors described above, the only way to know how much power your fridge is really consuming is to use a plug-in power meter.

### Fridge Wattage of Other Fridges

Using a Power Meter, I found that the small fridge in our office used between 90 and 100 Watts when the compressor was running. That resulted in 0.6 kWh used over 24 hours, or around 221 kWh per year. The Power Meter showed that the fridge was drawing power for only 6 hours and 10 minutes in 24 hours.

Commercial refrigeration is more complex to measure, but the opportunities for energy savings are much greater. Some of the businesses for which I have completed business energy audits initially spent well over half of their electricity costs on refrigeration. This is one reason why refrigeration makes number six in our top 10 causes of high power bills.

Check out this commercial refrigerator which is almost empty and still burning through over \$1,000 per year in electricity costs!

## Four Ways to Cut Fridge Power Consumption

1. Ensure fridges are well ventilated. Often fridges are jammed in between wall cabinets which makes their power consumption increase substantially.

2. Consolidate the number of fridges in use. If you have a spare fridge in the garage and only partially fill it, empty it and switch it off.

3. Use timer switches on drinks fridges and bar fridges. This way, any fridge that does not contain perishable food is only on when it’s needed.

4. Check and adjust the temperature settings. Freezers, in particular, are often set far too cold. Use a thermometer to check and change your settings. For domestic refrigeration, 4˚C for the fridge, and -15˚C for the freezer is sufficient and safe.

## Is Refrigeration Power Usage Even an Issue?

Don’t forget that refrigeration is only responsible for around 10% of energy usage in most homes. Although it can be much higher in businesses like cafes, clubs, and restaurants. So, if you want to cut your energy usage refrigeration is an excellent place to start, but I also recommend:

• Installing a wireless energy monitor to see your entire home or business power usage in real-time.
• Upgrade all your lights to LED – particularly those tube lights inside display fridges.
• Switch to more sensible forms of heating and cooling.
• Use these energy-saving devices to reduce the energy usage of other appliances.
