When shopping for a washing machine, there is an important parameter on the energy label on the machine that not many people know about, which is energy efficiency. So what is energy efficiency on a washing machine? Let’s find out with Tnhelearning.edu.vn right here!
What is washing machine energy efficiency?
You can simply understand that washing machine energy efficiency is a parameter that shows how much electricity the washing machine will consume for each kilogram of clothes to finish washing.
Energy efficiency is shown on the energy label affixed to the washing machine. You can easily check it on the washing machine when you buy it.
How is washing machine energy efficiency calculated?
Example: Looking at the energy label above, you will see that the energy efficiency parameter of this washing machine is: 11 Wh/kg . Thus, for each kilogram of clothes put in, the machine will consume 11 Wh of electricity.
If you put 7 kg of clothes in the machine, the machine will consume: 11 x 7 = 77 Wh (0.077 kWh) . That is, even if you wash it 10 times, it still doesn’t run out of electricity (1 kWh).
Notes when calculating washing machine energy efficiency
This energy efficiency is measured and announced by the Ministry of Industry and Trade, when measuring will usually use the normal washing mode , so this parameter may vary depending on the program you choose for your washing machine in reality. economic.
Although it is not absolute, you can use this parameter to compare the power savings between two washing machines.
