Which is better on a hot day? Fan or air conditioner

Basically, you can set the strength of the wind in weak, medium, and strong, and the fan makes your sweaty body comfortable and smooth with cold wind. The biggest merit is that you don't have to wait until the whole cools like an air conditioner because the rotating "head" blows the wind to everything in the range. Often there is a button on the back, which also allows you to fix the direction of the fan and consolidate the direction of the wind. If you put it in front of a window where the wind can easily enter, it will be cooler, but if the wind is bad, it will not get too cold. The whole room never gets cold, but it feels good to cool down like a breeze. The disadvantage is that it is difficult to clean.

You can adjust the temperature as you like, and if you close the windows and doors tightly, the room will cool down in a blink of an eye, so you don't have to worry about the heat. It takes some time to cool down, but once it cools down, you can spend your time comfortably in the room. In addition, the air conditioner not only cools but also heats, so it can be warmed on chilly days. While it has the advantage of producing cold air evenly, it may get sick due to being too cold, or it may cause poor physical condition due to the difference in temperature when going out. The biggest disadvantage of air conditioners is that insects invade from the outside if you are not careful.
