Air conditioning can be said to be a must for modern people to use household appliances, but many people have been plugged in the socket when the air conditioner is turned off, do not unplug, they feel that this will not consume electricity, because they think that the air conditioner will not continue to consume electricity when it is turned off. So will this practice increase the power in the end? In fact, the air conditioner is turned off and the plug is still powered.
As an electrical appliance user, many people actually do not understand that the plug is not unplugged is in standby. Because the electrical appliances are only turned off and the power plug is not unplugged, the power supply part of these appliances is still working, and this state is also known as standby. In this state, the air conditioner will generally consume slight power, but the power of the air conditioner when it is in standby will be relatively small, so even if the air conditioner does not unplug the plug, the monthly consumption of electricity will not be much.
Most people use air conditioning time every year is about half a year, but if the residential area is relatively large, the use of central air conditioning, then its standby energy consumption is relatively high, a central air conditioning standby to consume about 2 degrees of electricity a day, a month is 60 degrees, if we calculate according to the average electricity price of 5-6 gross, a month's electricity bill will also be more than a dozen dollars. If you use 1.5 air conditioners in a small room, you will consume 0.1-0.2 degrees of power in a week of standby, and 0.4-0.8 degrees of electricity in a month of standby. A month is also a few dollars lost in vain.
Then, in this way, many of our household appliances are still consuming electricity when they are not in use, if they do not unplug them. Like the TV after watching the unplugged, the TV picture tube is still in the filament preheating state, in the standby state, the TV power consumption of a day is about 0.5 degrees, a month is 15 degrees. There are also computers we often use, computers and wireless routers in standby power is about 5 watts, a month to consume 3.6 degrees of power.
Of course, there is also a drum washing machine, the standby power of the drum washing machine is about 0.7 watts, which is very small in household appliances, and consumes about 0.5 degrees of electricity a month. The most commonly used electric water heaters. Although the standby power of the electric water heater is not large, if the standby consumes about 2 degrees of electricity for a month. The difference is that in order to maintain the water temperature, the electric water heater will start working when the temperature difference is too large. Due to the different power consumption of each brand, in general, a 30 to 40 liter electric water heater has a power of about 2 to 2.5 kilowatts, and the working hour is 2 kWh of electricity. The larger the indoor temperature difference, the longer the working time, the more power is consumed.
In this way, the electrical appliances we use daily, although they have been turned off, but the plug is not unplugged, it will continue to consume electricity, although the same electrical appliances do not seem to consume much electricity, but if each home appliance is operated in this way, then a month down invisibly increased a lot of electricity, a year is also a lot of overhead. So in order to save the power consumption of the air conditioner, it is recommended to turn off the air conditioner about 10 minutes in advance before going out, even if the air conditioner is turned off, but the indoor room temperature will not rise immediately, within this 10 minutes there will generally be a cool feeling, if you develop the habit of turning off the air conditioner in advance, you can save a lot of power consumption.
