How much electricity does a refrigerator consume per day or month?

July 09, 2020

Of all household appliances, refrigerators are the most energy-intensive. Operating all day and night, even a television or heater is not as active as a refrigerator.

That's why its energy consumption is interesting. You might even buy a refrigerator at a discount , but its low energy efficiency will outweigh the price difference even in a year.

If so, how many kilowatts does the refrigerator consume per month? How can I reduce the electricity bill for this appliance to reduce energy consumption?

Energy consumption of an average modern refrigerator:

On average, 0.8 - 1.5 kilowatt hours (kWh) per day.
This works out to about 24 - 45 kilowatt hours (kWh) per month.

Please note:

If it is an energy-efficient model (A+++ class), it will consume approximately 0.7-0.9 kWh per day, which comes out to 21-27 kWh per month.
Older or less efficient models may use 1.5-2 kWh per day, which adds up to 45-60 kWh or more per month.

A simple method to calculate the energy consumed:

Read the annual consumption in the device's passport, usually in kWh/year. For example, if it says 300 kWh/year, divide by 12 = 25 kWh/month.

How does energy consumption change in summer?

In the summer, a refrigerator consumes an average of 15-30% more electricity than in the winter.

Reasons:

The outside temperature is high - the refrigerator works more often and longer to maintain the cooled temperature inside.
In the summer, the door is opened frequently (for drinks, ice, etc.), which creates additional strain.
Sometimes the sun's rays directly hit the refrigerator or the kitchen gets too hot, which affects its mechanisms.

Tip: If you want to cut costs this summer:

Do not place the refrigerator in a sunny place.
Check the seal (door rubber).
Adjust the temperature correctly — even in summer, 4-5°C in the refrigerator and -18°C in the freezer are sufficient; setting it higher unnecessarily increases costs.

Electricity consumption table for a standard-sized (approximately 250-300 liters) household refrigerator, opened several times a day and placed in a normal environment:

How much electricity does a refrigerator consume per day or month?

Before we move on to a detailed discussion, let me briefly tell you:

The energy consumption of a refrigerator depends on several factors:

Its energy efficiency class (A+++, A++, A+, B, etc.)
Volume (for example, 200 liters or 400 liters)
Intensity of use (how many times the door is opened)
Ambient temperature (the refrigerator consumes more energy in the summer)

What does energy consumption depend on ?

In addition to the factors listed above, the energy consumption of a refrigerator is affected by:

Electricity consumption class;
1/2 Presence of compressors;
Volume;
Outdoor temperature;
Technologies used.

It is worth noting that a refrigerator-freezer generally consumes more energy because it needs to maintain a lower temperature in the cooling chamber.

Without the above criteria, it will be difficult to understand how many watts a refrigerator consumes. We will give you some tips on how to defrost a refrigerator quickly and correctly.

One or two compressors :

Standard refrigeration units are usually equipped with one compressor. A characteristic feature of such units is the high power generated to ensure the functioning of 2 chambers: the refrigerator and the freezer. As a result, we have an increase in energy consumption, which cannot be said about two-compressor units.

Features of a two- compressor refrigerator :

Compared to the previous version, here each compressor is responsible for the operation of its own unit, which allows to reduce the energy indicator. As a result, the cost of electricity consumption is reduced.

The advantages of installing two compressors include the ability to turn off one of the compressors, thereby preventing any damage to the refrigerator.

Features of refrigerators with one compressor :

Single-compressor refrigerators are more energy efficient, but they cannot perform some of the operating modes of dual-compressor devices. However, Because of this, There is no shortage of buyers, and the price of such refrigerators is much lower than those with two compressors.

Total equipment capacity

A factor that must You should consider this before buying, as room appliances require significantly more electricity. To find out how many kW of electricity a refrigerator consumes, it is necessary to find out its total volume, including the freezer.

The exception is modern models with energy class A + and higher. Their technology of operation does not depend on the volume of the chambers.

Energy classes

The classes are determined by how much electricity a refrigerator consumes per month. The most efficient among them is <A +++>. Equipment that has these technical characteristics is considered to be a very economical model.

Class: Electricity consumption energy compared to the norm (100%)

A ++ - up to 30%;
A + - 31-43%;
A - 43-56%;
B - 56-74%;
C - 75-91%;
D - 92-100%;
E - 101-111%;
F - 112-125%.

It should be noted that you will almost never find classes E and F among the assortment of consumer electronics stores.

The temperature in the room where the refrigerator is operating .

The higher the room where the refrigerator is located, the greater the difference between the outside and inside temperatures. Therefore, the greater the energy consumption. For example, at a room temperature of 30 degrees (with a <+> sign), the appliance consumes much more electricity than at normal temperature conditions.
