Air conditioning is also stealing your electricity bill

As the pace of life accelerates, we have become accustomed to simplicity, convenience, and speed. As long as there is a remote control, I believe that 80% of people will never unplug the power cord. You don’t think it will cost you much electricity if you don’t unplug the power supply, but if you think about how many electrical appliances in your home are always on standby, if you count it this way, the amount of electricity wasted a year is by no means a small amount. Especially in summer, the big electricity users at home are air conditioners. Many friends have figured out a set of their own power saving tips based on their own usage habits. They are even more careful in their daily life, fearing that the use of air conditioners will bring high electricity bills.

　　Some friends and editors responded that after the home air conditioner was turned off, they found that even if the air conditioner was turned off, the electric meter in the house was still running, but we did not use the air conditioner or other appliances in the house. Why? Today, the editor will explain to everyone at Jianda why the air conditioner will still use electricity after it is turned off, and the meter will continue to run?

　　 Demystified Why does the air conditioner consume electricity even after it is turned off?

　　 This is because the power plug of the air conditioner is not unplugged, and the heating belt and transformer of the press are still working. But the power of the heating zone is generally 27-33W, and the power of the transformer is only 3-7W, so the power consumption is very small.

　　 But if the machine is not used for a long time, it is recommended to unplug the power plug. This will not only save electricity, but also be safer.

　　 The power consumed by an electrical appliance when the electrical plug is plugged into the socket (the appliance is not in use). Generally relatively small, about a few watts to tens of watts, but the power consumption over time is quite alarming. The annual standby power consumption of drinking water dispensers nationwide reaches 13.7 billion kWh.

In the standby state with the switch turned off but the plug is plugged in, the standby power consumption of commonly used household appliances are: air conditioner 3.47 watts, washing machine 2.46 watts, refrigerator 4.09 watts, microwave oven 2.78 watts, range hood 6.06 watts, rice cooker 19.82 watts, color TV 8.07 watts, video recorder 28 watts, DVD player 13.37 watts, VCD player 10.97 watts, audio amplifier 12.35 watts, mobile phone charger 1.34 watts, monitor 7.69 watts, PC host 35.07 watts, fax machine 5.71 watts, printer 9.08 watts. Adding these up is equivalent to the fact that these appliances consume 4 kWh a day when they are not working.

　　 As long as the electrical appliance has a mechanical switch, turning this switch off will not have a standby state and will not consume electricity.

　　 If there are no mechanical switches, only touch switches and remote control switches will consume electricity in standby mode.

　　 If there is a mechanical switch and a touch switch, of course, turning off the mechanical switch will no longer cost electricity.

　　 The air conditioner does not have a mechanical switch. Plug in it to stand by, and of course it consumes electricity.

　　 When the washing machine is not in use, the mechanical switch is turned off, so it does not cost electricity. During the washing process, the light touch switch is turned off, which consumes a little electricity.

　　The power consumption of the computer varies with the configuration of the optical drive and hard disk. When in the screen saver state, it does not save power; when in standby, it consumes 10% of power, and only the host works in standby. The power consumption of the host varies from 2 to 35 watts depending on the model and the standby options set in the system; generally speaking, The power consumption of the computer in the shutdown state is: 4.3 watts for the host, 1.9 watts for the display, and a total of about 6.2 watts
