When choosing any home appliances, they are constantly advised to pay attention to their power consumption, especially for household refrigerators , which are the only household appliances around the clock. But many consumers who do not have a special education do not even understand what this show means.
Therefore, in the article we will consider what is the power consumption of the refrigerator and how to calculate its average index. Power consumption is the amount of electricity consumed by the whole appliance in its operation, as it consists of heaters, bulbs, fans, compressors, etc. This capacity of the refrigerator is measured in kilowatts (kW) in order to know the average value, it is necessary to determine how many kilowatts electricity is consumed by them per day. This indicator is the main one for determining the energy efficiency of the device.
How to know the power of the refrigerator?
In order to determine what kind of power consumption of your refrigerator, you should look at the information sticker located on the outer wall or inside the camera. The same information should be contained in the operating instructions for this household appliance. There will be indicated the average nominal capacity of the refrigerator - 100-200 W / h and the maximum (when the compressor is turned on) - about 300 W, to maintain the internal temperature + 5 ° C with the external + 25 ° C.
Why did the concept of maximum power consumption appear? Because, the compressor responsible for pumping through the refrigerant circuit of freon, works, unlike the entire refrigerator, impermanently, but only if necessary (after the temperature sensor signal). And in some models, to maintain the temperature in several chambers, they are installed more than one. Therefore, the actual energy consumption of the refrigerator differs from the nominal value indicated.
But the inclusion of the compressor is not the only factor on which the change in the electricity consumption of the refrigerator depends.
What determines the power of the refrigerator?
With the same power consumed, different refrigerators can use a different amount of electricity. It depends on the following factors:
- its volume - the larger the volume, the greater the amount of energy consumed;
- the number of stored products - especially in the freezer;
- season and operating conditions - more is used in the summer and if the room is hot, and less - in the winter and in a cool room;
- the amount and power of the compressors installed in the refrigerator;
- quality and tightness of thermal insulation, especially sealing gums on the doors;
- availability of "No Frost" system or other additional functions.
Freezing capacity of refrigerators
With the concept of power consumption, the freezing capacity of the refrigerator is related.
The freezing capacity is the amount of fresh products that the refrigerator can freeze (their temperature should be -18 ° C) during the day, provided that the products are placed at room temperature. This indicator can also be found on the informative sticker or in the instruction marking "X" and three asterisks, usually measured in kilograms per day (kg / day).
Various manufacturers produce refrigerators with different freezing capacities. For example: Bosh - up to 22 kg / day, LG - up to 17 kg / day, Atlant - up to 21 kg / day, Indesit - up to 30 kg / day.
We hope that this information on the average power consumption, will help you when choosing a new refrigerator to choose the most energy-efficient model.
