Recently, the claim that “the air conditioner is on for 24 hours saves electricity even more” has sparked a buzz on the internet. Some netizens posted a video saying that they tested it themselves. If you don't turn off the air conditioner for 24 hours, the electricity bill is 118 yuan a month; if you turn it on late and early, it costs 198 yuan a month; and if you switch it on and off frequently, it's 490 yuan a month. Is that really true? The reporter learned from the power department that if you go out for a short time, you can not turn off the air conditioner, but raise its temperature by 1 to 2 degrees Celsius. This saves more electricity than starting and stopping frequently. But if you're away from home for a long time, such as a full day at work, it's more cost-effective to go home and start again.
