The air cooler has no compressor and is not at all related to air conditioning. However, the air cooler and air conditioning collocation is a good combination, the two can learn from each other. The impact of the air cooler on health is that indoor humidity increases.

The principle of the air cooler is very simple, that is, the water on the water curtain is evaporated by the wind blown out by the fan to achieve a very limited cooling effect. This inevitably leads to higher and higher humidity in the air inside the space. The combination of high humidity and high room temperature makes people feel more uncomfortable, and the feeling of sultry heat and humidity is more serious. Some people have said that ice crystals can also be used. Yes, adding ice crystals can cool the tuyere for a short time, but it's almost impossible to cool the room. This is because the storage capacity of ice crystals is very limited, and a small ice crystal can't carry enough cold to compete with the heat in the room. If you put your hand near the air cooler, you will feel cool. If you put your hand near the air conditioner, you will feel cold. That is the difference. Because the use of cold air will lead to an increase in indoor humidity, and air conditioning in the refrigeration will lead to indoor drying, so the use of air cooler and air conditioning is a good choice. One can avoid indoor air is too dry, two can help indoor air conditioning circulation, in the role of the fan can be properly adjusted to high air conditioning temperature, play a power saving effect. In addition, the water in the air cooler must be replaced in time. Because of the working principle, the water quality will deteriorate after a period of time, and it is easy to breed bacteria. Based on this situation, the use of air cooler can play a part in the role of air purification, equivalent to washing air.
