The air supply mode of air conditioner can be simply understood as the electric fan at home. The electric fan at home simply uses the circulation speed of air to make people feel cool, but it can't actually change the temperature. The air supply mode of the air conditioner is that the air conditioner hangs up and works normally. The air he sends out is still indoor air. He didn't exchange indoor and outdoor air, nor did he change the temperature. At this time, the plug-in machine of air conditioner is not working normally, so this air conditioner has played a role in accelerating air circulation and indoor air circulation.
Personally, I think this air supply mode is rather lame and useless. If the weather is hot, obviously you should turn on the cooling mode of the air conditioner and adjust it to a suitable temperature, such as 23 degrees or 25 degrees, so that you can feel cool. If the weather is not hot, you don't need to turn it on, because it is indoor circulating air, which is not suitable for outdoor use, like communication, and can't purify the air and improve the indoor air quality.
If you really want to purify the air, you can install an air purifier and a fresh air system, which can make your indoor air really pure and more helpful to your health. But the air supply mode of air conditioner is of little help to you. Just like the electric fan at home. Do you think even if the electric fan at home blows 24 hours a day, does it change the nature of indoor air? Not at all, it just speeds up the flow of indoor air.
