The living quarters of a person include many useful devices and equipment, without which it is already impossible to imagine comfortable living conditions. And each such element consumes electricity. But not everyone realizes how much can be consumed by a separately selected household device. But what degree of energy consumption each energy consumer has, every user needs to know. This indicator directly depends on the model of the device and its characteristics.

Electricity indicator
Without going into physical concepts, electricity can be called the type of fuel that is used to operate devices. Consumption is calculated in kilowatt-hours. In the instructions or technical passport, which is issued to any household appliance, the amount of energy consumed by it is indicated without taking into account the operating mode.
How many watts the refrigerator spends cannot be calculated using the data from the technical passport. This parameter is used only to install a cable of the required cross-section and further normal operation. The amount of energy consumption can only be fixed using
electric meter.Differences in energy classes
You probably know that the best option would be models with class A, A +. Models of this class are leaders in terms of efficiency. But if the model you have chosen has another class, this does not mean that you need to put an end to it.
There are currently 10 classes in total. They are marked with Latin letters starting with, A and ending with G, and additional ones can be marked with A +, A ++, A +++. The latter is currently the most economical. The difference in classes is given at the level of 12-14% in terms of the level of energy consumption per class. Therefore, when choosing, it is not necessary to strive for the highest level.
How to calculate the amount of energy consumption
Two units of measurement are used for measurement:
- watts (W),
- kilowatts (kW).
For counting real amount energy consumption is required to find out the power consumption in watts for your refrigerator.
You can take measurements with a multimeter on a specific power circuit, but this requires knowing where it is located. The measurement is taken while the compressor is running and the result is multiplied by 220 and 3.
For people who are poorly versed in the equipment, there is an easier option. It consists in the study of stickers and markings on the equipment itself, in which you need to find where the energy consumption data is indicated, as a rule, the manufacturer indicates all three parameters:
- minimal,
- maximum,
- nominal.
The maximum data is measured when the compressor is turned on, and due to the fact that its operation is periodic, and not constant, with idle time the parameters will be much lower. On average, the maximum power is 0.3 kW per hour, and the average is about 0.1-0.2 kW per hour.
Refrigerator power
How many watts a refrigerator consumes depends on many factors. The consumed power is the total amount of energy that the equipment can consume over different periods. It includes multiple components: a compressor (and more than one), a cooling fan, and a heater.
The main factors affecting power consumption:
- Energy consumption by components.
- Dimensions and volume of chambers.
- The presence of thermal insulation.
- Additional functionality.
- The presence of the No frost system.
- The temperature of the food to be put into the chamber.
- The amount of food.
- Operating conditions.
- External temperature conditions.
Changing these parameters can multiply the cost of equipment.
The instructions indicate mean refrigerator power in watts. For example, the capacity of the Atlant refrigerator is 250 W, which is a typical indicator for modern equipment of this type.

How to reduce energy costs
There are some basic tips on how to reduce energy costs:
- Look into the refrigerator less often. Thus, to reduce the number of door openings, during which there is a loss of temperature and, as a result, the inclusion of the compressor to replenish the required temperature.
- Do not leave the door open for a long time.
- Do not put hot pots and food in the cooking space. Only cooled down to room temperature.
- Remove ice from the evaporator and other chamber cavities periodically.
With all the obviousness of the above points, they really bring their favor with constant execution.
The actual capacity of the equipment sometimes exceeds the declared one by several times. A huge number of factors can influence the level of energy expenditure. To understand the costs of your equipment, it will be enough to read the information in the instructions. With proper operation, these values can even be reduced.
