Air conditioning may be a way to spend the hot summer days, but in some specific environments where there are only fans without air conditioning, how to make electric fans blow cold air is also a topic of concern for many friends.
Reasonable opening and closing of doors and windows
Open doors and windows in the morning and evening when it is cool, so that the air circulation, and in the daytime, especially at noon, the doors and windows will be closed, in order to isolate the outdoor hot air, and pull the light-colored curtains, blocking the sun, reflecting the heat radiation, you can make the room become cooler.
Balcony greening, courtyard greening
Some information shows that in the courtyard balcony planted grapes, petunias, wall climbers and some flowers and plants, that can be ornamental and can make the attached wall cooling 5 ℃ ~ 14 ℃, so that the indoor cooling 2 ℃ ~ 4 ℃.
Indoor use of fans and water evaporation cooling
For example, after wiping the floor with a wet mop, turn on the ceiling fan to make the ground moisture evaporation to absorb heat; you can also use a pot of cool water (preferably with ice) in front of the fan, which can reduce the room temperature and increase the humidity of the air.
Maintain a good indoor environment
In summer, it is advisable to clean up the room, so that the room has more space, which will make people feel comfortable. Do not mess up the room, which not only makes people feel stuffy and suffocating, but also makes people feel irritable.
With wet towel cooling
You can find a towel wet in front of the fan, and then turn on the fan, hot air instantly into a cool breeze there! You can also hang a wet towel in front of the window, as long as there is wind, the effect is the same. You can also use other liquids, such as with diluted perfume, flower essences, etc.
Principle: the wind blows, so the towel on the surface of the liquid air flow speed up, the liquid accelerated evaporation, liquid evaporation from the air to absorb heat, so the temperature decreased.
