The principle and benefits of dehumidifier blowing hot air
During the rainy season and cold winter, for southerners, the issue of a room being damp and humid is a pressing issue that needs to be addressed immediately. In winter, it is relatively good, after all, there is an electric oven, but what about the rainy season? The dehumidifier is about to show its effectiveness. Today, the editor and everyone will learn about the system knowledge of dehumidifiers.
The principle of dehumidifier blowing hot air
In theory, air passing through a condensing tube will make the air cool. But the operation of the dehumidifier itself generates heat. According to the law of invisibility of matter, air cools, and the heat in the air is not expelled from the outside, so it remains indoors (Unlike air conditioners that carry heat outdoors, combined with the heat generated by machine operation, the outlet air will be "hot". Most dehumidifiers use the principle of semiconductor refrigeration to force the condensation of water vapor in the air. There is a special semiconductor material that becomes very cold on one side and very hot on the other after being electrified, which is used in dehumidifiers.
After the fan blows wet air through the semiconductor cold surface, the water vapor condenses and the air humidity decreases, thus achieving the purpose of dehumidification. At this point, the dehumidified air should also be introduced into the heat surface to implement forced air cooling on the semiconductor, taking away the heat of the semiconductor. In this way, the dehumidifier can work for a long time without burning out. The air at the air outlet is air-cooled with semiconductors, so it will be very hot
Application of dehumidifier blowing hot air
This type of refrigeration semiconductor material is widely used in small refrigerators that do not require refrigerant; In fact, the dehumidification principle of air conditioning is similar to that of a dehumidifier, except that the condensation of the air conditioning is indoors and the heat is removed by the outdoor unit, without the need for air that has already been dehumidified to cool. So when the air conditioner is dehumidifying, cold air comes out; The water from the dehumidifier is very clean; In some arid Gulf countries, this condensation principle is also used to extract fresh water on a large scale from the sea breeze
The benefits of blowing hot air through dehumidifiers
The hot air outlet of the dehumidifier can act as a desiccant. In humid indoor conditions, the driving force of hot air is more conducive to the drying of indoor air. The air outlet of the dehumidifier emits hot air, which can have the effect of drying clothes. During the rainy season or cold winter, clothes that have been washed are not easy to dry, so a dehumidifier can be used. Evaporate the water molecules on the clothes, making them dry and fragrant.
Dehumidifiers, as the name suggests, are used for dehumidification rather than for cold rooms, so the wind is hot. When the walls and furniture in the room are very damp, it is precisely when a dehumidifier is needed. If the wooden furniture is not properly treated immediately, it will gradually become damp and infested, so if you don't have a dehumidifier at home, go buy one quickly!
