All about the power of the refrigerator
To power the fridge directly related to such characteristics as energy consumption, energy efficiency, overall performance, additional features, and power freeze. Power is called the rated amount of electricity that the unit spends on its operation, while energy efficiency is a rational amount of energy consumed by the running refrigerator.
The freezing capacity of the refrigerator is the ability to freeze a certain number of products per day.
The very power of the cooling unit depends on its external dimensions, and the compressor power, fan power, insulation gasket and use additional functions. Various manufacturers produce refrigerators, the freezing capacity which varies markedly. Class of unit usually written on the rating label – the letters A, B, C, D, E, G, mean degree of its efficiency. Refrigerators with the label A, B or C represent economical class, with the letter D – intermediate value, and E and G are high power consumption of the unit. Today the market is mainly dominated by refrigerators A, b and C-class.
Find out the capacity of the refrigerator
To independently measure the power of a modern refrigerator, you can use a multimeter, measure them a reading circuit of the refrigerator while the compressor is running. The values obtained must be multiplied by the mains voltage (220V), however it should be noted that when the compressor starts, the chain will go current in excess of the nominal value of the voltage two or three times. Therefore, the reading must be multiplied by 3 – if the power measured for the connection of the voltage regulator, the multiplier also need to add the required capacity stabilizer.
The average power of a modern cooling unit, stated in the instructions that traditionally is not more than 250 watts, but after measuring it can reach 500 watts.
To reduce power consumption of the refrigerator, open the appliance door briefly and not too often. Also, the air heated by the rear wall, must circulate freely so that the Assembly rarely switched off and consumes less energy. For this ventilation grill refrigerator need to be kept open. Food before placing in the fridge must be cooled down, and the ice accumulated on the freezer evaporator to remove at least once a month.
Advice 2 : How to know the capacity of the refrigerator
The refrigerator is one of the domestic appliances, which is open around the clock. Therefore, the choice of the appliance should pay attention to his power, to know what amount of electricity it consumes.
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.
