Power consumption of the domestic refrigerator

Often, when buying a refrigerator in your home, most people are only interested in the appearance and price, and only then the power consumption of the refrigerator. As the statistics show, a significant part of buyers make their choice in favor of a well-known company, thereby justifying the huge costs of advertising. Many people do not think that the use of electricity by a cooling device is about 30% of monthly consumption. Every year the savings are becoming more urgent, and when buying it will be useful to pay attention to the power consumption in kilowatts (kW), because the refrigerator is permanently connected to the network and consumes electricity 24 hours a day, 365 days a year.

The characteristics of the device are indicated in the instructions for the refrigerator, but if it is not at hand, they can be found on the information sticker, which is located on the back wall or inside the refrigerator compartment. The average power is in the range from 100 to 200 watts per hour, this power is enough to maintain the temperature of -5 ° C with the environment at + 25 ° C.

The main parameters on which energy consumption depends

The main part of the refrigerator is compressor (its motor). This device compresses and pumps refrigerant vapor, thereby cooling the surrounding space. The average efficiency and power consumption of a refrigerator are directly dependent on such factors as:

1. The presence of 2 compressors in the system.
2. Volume of the refrigerator.
3. The temperature in the room where the household appliance is used (the higher the temperature, the more energy is needed to maintain the temperature in the cell)
4. System availability No frost (dry freeze).
5. Ice generator function.
6. Exposed temperature settings inside the chambers.
7. Tightness of the refrigerator.
8. Frequency of opening doors.

You also need to take into account the number of family members and the average weight of products that will cool the device per day.

Choosing a refrigerator according to energy class

In home appliance stores, many of us have paid attention to energy efficiency stickers in the form of Latin alphabet characters from A to G. Recently, there have been A and A + or A +++ labels. These designations mark more advanced models from their predecessors. So, for example, a device with energy consumption of class D consumes 100%, and class A will consume 55% less energy, type A + 65%, type A ++ consumes 85-90% less energy and A +++ to 100% less electricity. This data is conditional, since a small class A device will consume much less energy than an industrial refrigerator with the No Frost A +++ system.

What function is affected by the power of the refrigerator

The power of the refrigeration unit directly proportional to its energy efficiency, and also affects the operation of its additional functions.

Energy efficiency is determined by rationality use of the instrument electricity. Thus, a class A refrigerator consumes an average of 100 watts per hour, 1.5 kW per day, and for the year this figure can vary between 365-550 kW.What consumption you will leave depends on how well the owner will use his refrigerator.

Freezing capacity is an indicator that determines how much food (in kg) the freezer can freeze in one day.

The information label contains information with the “X ***” indicator. The number of stars next to the symbol depends on the number of frozen products. The freezing capacity indicator is measured in kilograms per day and indicates the number of products (in kg), which it can cool to -18 ° C in 24 hours. The default room temperature for food is + 18-20 ° C. For ordinary household refrigerators when using a single-family house (out of 3-4 people), the freezing capacity should not be lower than 9 kg / day.

An example of brands of refrigerators with different freezing productivity of products:

• Atlant - an average of 20-21 kg per 24 hours;
• Samsung - up to 18 kg in 24 hours;
• LG - from 15 to 17 kg per day;
• Hotpoint-Ariston - about 18 kg in 24 hours.

All the above information will help you choose the most suitable version of the refrigerator, depending on the purpose of use, electricity consumption and speed of freezing. You may also find information about most reliable refrigerators.
