The power consumption of a washing machine is determined by the class, implying information about the amount of electrical energy consumed during one cycle of the procedure in the case of maximum load.
Subspecies of energy consumption of the machine
Based on this information, they are guided, estimating the efficiency of the unit. It is possible to obtain information by reading the corresponding marking located on the body of the unit. Invented by Europe 7 levels of energy consumption, indicated by marking with Latin letters: A;AT;WITH;D;E;F;G. Plus is added to aggregates that exceed the standard boundary skills.
- Installations A are extremely economical, equipment of a subspecies A requires 0.17 - 0.19 kWh.
- The consumption of a washing machine of class B varies between 0.19 - 0.23 kWh.
- - 0.27 kWh.
- Household appliances of subspecies D belong to the economical category, the “intake” level varies within 0.27 - 0.31 kWh.
- Devices that show Е-F indicators are characterized by increased demands, the consumption level is0.31–0.35 kWh, 0.35–0.39 kWh, respectively.
- Non-economical, let's call devices class G, capable of “taking” more than 0.39 kWh, extremely much, unjustifiably.
- The antipode, the exact opposite, is the A + category technique."Occupies" less than 0.17 kWh, ensuring the competitiveness of products.
How much a washing machine consumes is determined by laboratory tests, an appropriate level is assigned to a technique.
Value “P”
Power, which determines the rate of energy consumption, plays a key role. Washing machines show performance in the range of 2-4 kW.High numbers are due to the need to heat the water, they have special requirements for connecting equipment. Associated with restrictions on the current flowing through the wires. The power of the washing machine is 2.2 kW, the current consumption is 10 A. The capacity of the copper wires is 14 A / mm2, the parameter for aluminum wiring is 10 A / mm2.The device, eating 2.2 kW, is connected, having previously calculated the cross-section of the cores.
If the P technology exceeds the cable allowed through, you will need to convert the figure to amps using the formula: N( kW) × 4.35 = A. The empirically looks like this: 4 kW × 4.35 = 17.5 A. Divide the result by the number of square millimetersabove. Compare required information. We conclude: the connection of a machine with a power & lt; P & gt; is performed using aluminum wire with a 2 mm2 core section or copper wire with a 1.5 mm2 section.
Ratio of maximum power and energy
Now consider the ratio of the maximum requested power to the cost of energy cycle. The largest & lt; P & gt;unit ranges from 2.15–2.3 kW.With a maximum setting of a physical quantity, the consumption is 0.94-0.95 kWh. The indicators of class B and C class devices are identical. The power consumed by the washing machine rarely exceeds 2.2 kW, making it possible to rely on resource consumption of 0.9 kWh. The dramatic differences are felt in the case of the technique relating to the subspecies D in this case, the "max" power level can also be 2.2 kW.Consumption reaches 5.2 kWh, very much.
Calculation of electricity consumption, based on the power of the device
What settings mean for the average consumer in terms of the number of kilowatts required during the month. To simplify the understanding of the question will help the following simple scheme: 1000 Wh = 1 kWh. In other words, the device has the greatest & lt; P & gt;4000 W, for 1 hour of operation will consume 4 kWh of electrical energy. Measurements of the required amount of & lt; P & gt;one cycle is conditional. Inform the consumer how much energy will be consumed by the device, functioning for an hour, heating water to a temperature of 60 ° C.
Consequently, the power consumption of a washing machine is determined by additional factors:
- type of fabric;
- water temperature;
- number of turns;
- drum loading level.
If the unit states: “takes” 0.94 kWh, so much the device will use during the hour of work at a water temperature of 60 ° C, fully loaded with cotton fabric items. If the procedure is carried out at a temperature of 30 ° C, all other conditions being equal, 0.47 kWh was expended.
Conclusion
The power consumption of the washing machine is directly determined by the maximum power, the actual electricity consumption is determined by the operating conditions of the equipment. Information regarding the limit value & lt; P & gt; , consumption under standard conditions( cotton fabric; t = 60 ° C) is marked with a special sticker. Guided by the above information, the consumer will choose the optimal mode of operation that meets the requirements regarding the quality of the procedure, the need for electrical energy. Proper use of information will save money on the maintenance of the machine, will help to optimize the family budget. Focusing on the numbers of stickers, making the right choice, acquiring an acceptable technique for washing clothes.
