Today, no one will be surprised by a humidifier, and you can find this device in many homes in our country. Despite the great popularity of devices, the principle of their work remains unchanged and has a number of design features, which will be described below. Conventional household humidifiers (industrial requires separate consideration, since arranged difficult, and by their action resemble the work of air conditioners, than conventional moisture evaporators) are divided into traditional and ultrasonic. Consider, how a humidifier of one type or another works.
What do you need a device for?
Many are wondering, what you need a humidifier in the room? It will not be difficult to answer this question, if you remember, that man is more than on 70% consists of water. How much moisture do people lose in arid climates, in terms, when all radiators are working, convectors and so on? In such conditions, the skin dries and peels, mucous surfaces and problems with the respiratory system may worsen. Devices of this type (including a portable humidifier) needed for just that, to minimize the negative effects of the arid microclimate of modern apartments.
Different types of humidifiers work differently. The basis of their work can be ultrasound, hot or cold evaporation, water "saw". Therefore, when choosing a device for home or industrial enterprises, it is necessary to take into account the algorithm of its operation.
How a humidifier with hot evaporation works
If the purpose of humidifiers is more or less clear, it remains to understand the peculiarities of their functioning. The basis of these devices is the principle of liquid evaporation (transition of water from one state to another). Water begins to evaporate during boiling, and the device emits steam, dissipated by a fan. The boiling process itself is achieved by two (pairs) electrodes, immersed in a tank of liquid. They are closed and this begins to heat the water.
The principle of operation of the humidifier hot evaporation
How long should such a device work? As long as there is liquid in it. When it all evaporates, the electrodes open, and the supply voltage to them is automatically blocked. It is for this reason that you should not worry, that a humidifier can cause a fire. In some cases, it makes sense to connect the power cord after that, as a device assembled and ready for use. Some models can operate from USB, then these compact devices are designed for humans, who work a lot on the computer.
If any malfunction is detected (broken tightness, there are spots of stains or a damaged power cord), the appliance must be taken to a service center immediately.
Due to its features, this humidifier constantly operates in conditions of increased danger (high temperatures, electric current and water are in close proximity and interaction in one building).
The humidifier consists of a small number of units and aggregates:
- Water container.
- Fan.
- Filter.
- Heating element (boiler).
- Ionizer (optional, is not installed on all models). With this option you can not only moisturize, but also to enrich oxygen indoors with negatively charged ions.
To achieve an aromatic or inhalation effect, simply add to a special tray (or water tank) aromatic oil, and wait for the appropriate effect. However, you should know, that not all humidifier models support this feature.
How long should the humidifier work, that the level of humidity in the room decreased to comfortable? It all depends on many factors: what time of year, degree of dryness / ventilation of the room, wall material, etc.. P.
How traditional devices work (cold evaporation)
The principle of operation of these devices seems even simpler, than in fellows. Cold evaporation occurs mainly due to that, that liquid, located in the tank, flows down on special tubes in the pallet, and from there falls on the evaporating elements. Then the fan comes into play. It blows the directed air flow through the evaporator, as a result, the output is purified moisture. Water, fed to the evaporator, under air pressure from the fan passes through the antibacterial filter and leaves the nozzle in the form of moisture. So, a disinfectant effect is also achieved, which is very important in warm weather, when the number of harmful bacteria and organisms greatly increases.
The disadvantage of this type of device is the frequent need to replace filters. On the average, the service life of the paper antibacterial filter is 2-3 months. There are analogues, which can be operated longer, up to six months, but they are worth it, in accordance, more expensive.
The principle of operation of the humidification evaporator
Though, that the principle of operation of the "cold" humidifier is quite simple, there are models with different types of moisture spraying. Example, in more expensive models, plastic discs are used instead of filters, perforated with small holes. These disks rotate during operation, and absorb drops of water from the pan. Electrodes are responsible for disinfection in such humidifiers, which are in the pallet.
The advantage of "cold" humidifiers is autonomous work, the humidification process in them is self-regulating. The humidity level will be maintained in strict accordance with the specified indicators. If the humidity has reached the required threshold, the intensity of work is reduced to almost a minimum. Due to this feature, the traditional evaporator is recommended to be located near the heater, radiators or convectors. In this case, not only heating of the circulating air will be provided, but also its moisturizing and cleansing, which will significantly enhance the effect.
The principle of operation of humidifiers of ultrasonic type
Unlike humidifiers, discussed above, this type of device uses a very interesting principle of operation. The liquid from the tank enters a special plate, which begins to vibrate with ultrasonic frequency. The oscillations break the water into the smallest drops, forming something like water dust or steam. As a result, a cloud is formed, which is blown out of the device by a fan, located inside. In other words, during operation, the ultrasonic humidifier creates a mist.
The principle of operation of the ultrasonic humidifier
It may seem, that water dust, which occurs due to the frequency of vibration of the disk, hot. Actually water particles, crushed by ultrasound, are cold, and do not pose a danger to children, not for adults, you can safely touch them.
To find out, how much more you need to reduce the humidity level in the devices install a humidistat.
The disadvantage of this type of humidifiers is the lack of purification of the released moisture. That is, water pollen, which is released into the space of the room does not pass any filtration. Besides, it is recommended to use only distilled water in ultrasonic humidifiers.
The advantage of this device is safety in operation and a fairly simple device, as well as a reliable and proven method of work.
The principle of operation of atomizers (spray type devices)
How does the "atomizer" humidifier? It should be noted, that such devices are used only on an industrial scale, where it is necessary to moisten large areas. Moisture droplets turn into fine dust, making a path of several tens of centimeters from the nozzle nozzle. Spraying is achieved due to strong pressure.
The principle of operation of industrial humidifiers
The disadvantage of this type of device is the high price. The advantage of atomizers is high productivity.
Conclusion
As you can see, the principle of operation of the humidifier depends on several aspects, example, from his appointment (domestic or industrial), type and internal structure. What unites these devices is not the principle of operation, and the desired result is the required level of humidity in the room.
