Capacity of the refrigerator
Capacity of the fridge is the total amount of electricity that it consumes at their work. This includes the appliance of various kinds of heaters, fans, lights and compressors.
The capacity of domestic refrigerator is measured in kilowatts (kW). In order to know the average power value of the device, it is necessary to determine how many kilowatts of electricity it consumes in one day. The resulting figure is the key to determine the efficiency of the refrigerator.
About power consumption of a refrigerator purchased can say the information label, located usually on the outer wall of the device or within the camera. This information must necessarily be contained in the instruction manual of a domestic refrigerator.
The user usually specifies the average nominal power of the refrigerator: 100 - 200 watts/hour and the maximum (which is fixed when you turn on the compressor) - about 300 watts. The power required to maintain the internal temperature of 5°C when the external temperature is 25°C.
The concept of the maximum power consumption specified in connection with the fact that the compressor is responsible for pumping around cooling circuit of freon, it works intermittently (unlike the refrigerator), and only after a signal of a specific sensor temperature changes.
Some models of refrigerators have a number of compressors needed to maintain the temperature in a few cells. In this regard, the actual energy consumption of household refrigerator is different from the nominal indicators which are specified in the attached with the refrigerator of the user.
Factors influencing energy consumption
In addition to compressor power of the refrigerator is affected by the following several factors:
- volume of the refrigerating chamber – what it is, the more the quantity consumed by the device power;
- number of products – especially those located in the freezer;
- seasons and operating conditions;
- the number and capacity of compressors that are installed in the refrigerator;
- the quality and integrity of the insulation, in particular the sealing gum on the door;
- the presence of the No Frost system and other additional functions.
In order to buy the product with the lowest power consumption, it is necessary to read carefully the attached to the product manual. Because the correct operation of the device will help reduce power consumption and extend the service life.
