It is even hotter in the room when it is hot. I don't know which is better, tower fan or air conditioning fan.

Let's choose a tower fan. Air conditioning fans are too troublesome to use. It is cooled by circulating water through a small pump. If there is no ice in its water tank, the cooling effect will have no effect at all. When the water tank is filled with ice, the wind blows on the body and the moisture is heavy. Long-term use is easy to get arthritis. If possible, it is best to install air conditioning in the bedroom, which is convenient and comfortable to use, has no noise and has a good sleep effect!
