The principle of operation of the air humidifier, the nuances of operation

Design and principle of operation

The climatic device consists of a container in which the main supply of water is located, and the base of the device, with an emitter located in it. A dosing valve is installed in the main water reserve tank, which serves to maintain the required water level in the compartment with the emitter, preventing excess. In addition, a fan is installed in the humidifier to blow out water sprayed by the ultrasonic element.

Almost every modern humidifier has an electronic control and a hygrostat to accurately measure humidity levels. Many manufacturers equip their devices with ionizers, various filtration systems and many additional programs to make using the device more comfortable.

The operating principle of an ultrasonic humidifier is easy to understand.

1. The main unit of the device is the emitter. It looks like a washer made of piezoceramic ceramics, with silver-plated electrodes exposed.
2. When alternating current is applied to it, this element begins to vibrate at an ultrasonic frequency. When a certain power is reached, the vibration speed increases to such an extent that it begins to break the surface of the water into tiny particles.
3. The water, converted by the emitter into an aerosol in the chamber above the ultrasonic element, is blown out by an installed fan. Water mist fills the room and increases air humidity levels to user-set limits.
4. The hygrometer installed in the device will show the relative humidity of the air, and the user always has the opportunity to stop the device from executing the program or increase the power of the humidifier if there is insufficient humidity.
5. After the device reaches the required humidity values, it stops and is in standby mode. After the moisture content in the room air decreases, the device automatically turns on and the cycle repeats.

The role of the humidifier

Before you make a humidifier at home, you need to understand why it is needed in general. It is especially difficult to maintain the air of normal humidity in a room in winter, since centralized heating dries it out, and breathing dry air is fraught with consequences. These include respiratory tract disease, allergies and other troubles.

Do-it-yourself air humidifierIt is especially important to have it in a house where there is a small child, since his body is still imperfect and requires special conditions for normal growth and development.

All humidifiers perform one important function: they maintain the humidity level in the room at 40-70%, which is considered optimal for humans.

Ultrasonic

- with this method of humidification, the role of an evaporator is played by a plate vibrating at an ultrasonic frequency - due to this, the water falling on it is sprayed into a fine mist. This is the most popular operating principle, and it is also considered the most suitable for home (household) humidifiers. The reason for this is a number of advantages. Firstly, the “cloud” is at room temperature and the risk of getting burned by the steam is zero, which is especially important if there are small children in the house; however, some models may provide the ability to heat the steam (see “warm steam”). Secondly, ultrasonic models have good efficiency and performance with low power consumption. Thirdly, ultrasound is not audible to humans, and the main noise is created by the fan - and the level of this noise is low. Fourthly, devices of this type can be made lightweight, compact and convenient for travel. The disadvantages of ultrasound include the fact that it “evaporates” not only water, but also salts dissolved in it. In practice, this means that you need to use well-purified water for work - otherwise a difficult-to-remove white coating may appear on objects in the room.

Difference from a steam generator

There are two types of household humidifiers. Some work by increasing the evaporation area, others by heating the liquid until steam forms. In both cases, water evaporation occurs naturally; we won’t talk about steam generators today.

Most modern household appliances use a piezo emitter - a plate that vibrates at an ultrasonic frequency. The principle of evaporation here is this: water is broken into very small particles, a fine suspension, which cannot “stick together” back and continue to exist in the form of water vapor. The advantage of dispersed humidifiers is low energy consumption and the almost complete absence of scale in the device itself, which affects its durability.

Steam

This type of humidifier works by evaporating water by heating it to a boiling point. That is, the air is saturated with moisture due to hot steam. It is superior in power and performance to traditional ones, and can increase the humidity in the room to 60% or higher in a fairly short time. It can also be used for inhalation and aromatherapy.

Ultrasonic humidifier: disadvantages and advantages

Automatic devices are equipped with sensors whose functionality includes diagnosing the conditions in the room and selecting the appropriate program to maintain a comfortable microclimate in the room. Filtration systems are built into the air humidifier, which allows you to reduce the concentration of dust in the room. Some devices are equipped with water filters. They remove unwanted salts and other impurities from tap water.

Advantages of climate control units

Ultrasonic air humidifiers have a number of obvious advantages, which are worth dwelling on in more detail:

• minimal noise during operation;
• water is sprayed into microparticles, creating a “cold fog” effect;
• high ergonomics, compact dimensions;
• presence of a built-in hygrometer;
• maintainability of the device.

Disadvantages of ultrasonic devices

Like any technology, climate solutions also have certain disadvantages. Since an ultrasonic humidifier often works with untreated water, a white coating often forms on the furniture around the device - this is the main “disease” of devices of this type. We are talking about salts present in water. When the “cold fog” evaporates, they settle on the furniture, floor, and objects in the room.

As for the ultrasonic emitter itself, it is absolutely harmless to the health of humans and four-legged children. When you inhale steam containing salt particles, they easily enter the lungs. They are invisible to the body of a healthy person, but allergy sufferers and asthmatics will have a hard time. In especially severe cases, attacks of suffocation occur.

It is useful for people with respiratory problems to stay in the room where the device is installed, because the danger of drying out the nasopharyngeal mucosa is eliminated.

The best ultrasonic air humidifier will also have a place in a child’s room, because such a useful device should certainly be in every residential building. The device normalizes respiratory function, saturates the blood, internal organs and brain with oxygen. In a room with optimal humidity, breathing is easy and simple, and sleep is deep and sound.

Pros and cons of an ultrasonic humidifier

The characteristics of ultrasonic air humidifiers distinguish them from steam and classic models. The devices have several important advantages:

1. Ultrasonic units are equipped with very quiet, low-power fans. During operation, they make almost no noise; there are also no sounds of boiling or gurgling water.
2. The devices consume little energy and do not increase electricity bills. Membrane devices are twice as economical as standard steam humidifiers.
3. The units begin to improve air quality almost immediately when turned on. Ultrasonic devices do not spend extra time heating water and supply cold mist to the room within a few seconds after being put into operation.
4. Since the high-frequency membrane humidifier does not boil the liquid in the tank, there is no risk of accidentally getting burned if the device is tipped over or if you carelessly touch its hot parts.
5. High-frequency units are the most unpretentious in maintenance. They still need to be washed periodically to prevent limescale build-up. However, scale in an ultrasonic humidifier does not form as quickly and actively as in classic and steam models.

Most high frequency evaporators come with a water demineralization cartridge that lasts a long time and rarely needs to be replaced. If the device has additional fine filters, then they need to be reinstalled more often. However, the price of such elements is low, and they are easy to find on sale.

However, ultrasonic humidifiers have certain disadvantages:

1. Only water purified from impurities should be poured into the unit. Ordinary tap liquid is absolutely not suitable for a membrane device. You should also not use boiled or home-filtered water.
2. Ultrasonic devices are more expensive than steam and traditional humidifiers. The more additional useful functions provided in a particular model, the higher the price.

The operating principle of an ultrasonic air humidifier is based on spraying a cold fine suspension. Since the liquid does not boil, the mineral impurities present in it do not settle to the bottom of the container. They remain in water particles and enter the air. Owners of ultrasonic humidifiers very often encounter the appearance of a white coating on furniture and household appliances. Such dust is precisely the remains of mineral salts.

Even the use of distilled water does not always completely solve the problem of white plaque.

In general, ultrasonic devices have more advantages than disadvantages. But they have their own characteristics and require a competent approach to operation.

Rules of use and care

You will have to say goodbye to some of the advantages of a ultrasonic humidifier if you do not comply with the operating requirements. Do not forget that all humidifiers are energy-dependent devices that operate on an electrical network, so they are a priori dangerous if handled carelessly.

The best place to install a humidifier is a free space in the center of the room. This way the moisture will spread evenly around the entire perimeter of the room.

Some operating standards are prescribed by the manufacturer, others are well known and do not require reflection in the instructions.

So, in order for the humidifier to work for a long time, properly and without causing trouble, follow the rules:

• Remove the tank to fill with water only when the power is turned off.
• Use filtered water. If the device has filters, change them on time.
• When using hard water, deposits are deposited inside the structure. To prevent this from happening, the device is regularly cleaned with a solution of citric acid (per 1 liter - 30 grams of dry matter).
• In addition to citric acid, it is allowed to use vinegar, special products for plastic, soap solutions without antibacterial inclusions, and anti-scale agents.
• For reading, you cannot use alcohol solutions, acid other than citric acid, chemical solvents, oils, bleaches, abrasives, or hard brushes. Washing parts of the device in the dishwasher is also prohibited.
• The body of the device is wiped with a micro-lint cloth soaked in water, the tank is removed, soaked and wiped, and the internal elements are also soaked in the solution for 15 minutes.

If the device has an electronic display or indication, carefully monitor the signals and follow the prompts. Manufacturers have tried to make it as comfortable as possible for users of UV devices to use them.

If the device breaks down and you cannot fix it yourself, we recommend contacting a service center. The warranty on some devices is 1 or 2 years, during which time you are required to repair or replace the equipment free of charge.

Why do you need a humidifier?

When the heating season begins, you need to monitor this even more carefully. After all, due to heating, the air is additionally dried out, which negatively affects well-being.

More precisely, when heating devices operate, the relative humidity inside the room can decrease by up to 20%. For comparison, in the Sahara this parameter is at least 25%. That is, we can say that many people work in conditions that can be compared to desert conditions.

Of course, to solve this problem, you can use “grandmother’s” technique - hang wet laundry throughout the house or apartment. But the obvious disadvantage of this method is the inability to maintain the required humidity.

To ensure maximum performance of the humidifier, it should be turned on in an enclosed area.

The best solution would be to purchase a specialized device - a humidifier. With its help, you can easily maintain a certain humidity in both office and residential areas. Such a device will help create a truly favorable and comfortable microclimate for humans.

A distinctive feature of modern models of air washers is that they automatically maintain the user-specified humidity level. This increases the efficiency and safety of operation of such a device.

If you spend money on such a device, then after some time you will notice that household members, in particular children, get sick much less often. At the same time, the skin will become smoother and silkier, which allows you to slightly slow down the aging process. In addition, viral activity is greatly reduced in humidified air.

Dry air can cause allergic reactions.

Due to low humidity, dust particles quickly move into the respiratory tract and irritate them

Optimal humidity is important not only for people, but also for wooden or paper products.

That is, by purchasing an air washer you can protect furniture, books, paintings, frames, documents, parquet, musical instruments and much more from drying out, cracking and irreparable damage.

Ultimately, normal humidity in the room will have a beneficial effect on the plants. Indeed, in most cases, representatives of the tropics stand on the windowsills. Dry climates have a detrimental effect on such plants. But if an optimal microclimate is created, they will grow more intensely, bloom more profusely and not turn yellow.

Existing types of air washers

Before you go to the store, you need to understand in detail the existing types of devices - there are thousands of options on the market, differing in power, the presence of any additional functions and, of course, price.

How to decide on the type of equipment?

The first thing you should pay attention to when choosing such household appliances is the type of humidifier. All models on the market can be divided into the following categories:

• ultrasonic;
• steam;
• classic;
• sinks;
• climatic complexes.

Each type has its own advantages and disadvantages, which must be taken into account when choosing. Moreover, each of them works according to its own principle, so some models are not recommended for installation in rooms where children live.

Ultrasonic humidifier options

The most common are devices that evaporate water due to ultrasonic vibrations of a very thin membrane. It was the use of innovative technologies in the design process of these elements that brought the devices recognition from millions of buyers around the world.

The operating principle of ultrasonic devices: water becomes steam due to high-frequency vibrations. That is, air is sucked from the room, after which it passes through the device and is saturated with liquid. Then it returns to the living space, but in the form of damp fog.

The resulting air does not heat up. Therefore, you don’t have to worry about getting burned by it. Accordingly, ultrasonic humidifiers are completely safe for small children, which makes it possible to install them in a children's room.

Devices that evaporate water using high-frequency vibrations can be used not only in residential premises, but also in greenhouses and winter gardens

If you have antiques at home that require special, careful care, then such humidifiers will be the optimal solution. In this case, antique furniture, jewelry, parquet flooring, musical instruments and much more will not be affected by dry air.

Among all the devices on the market, ultrasonic devices stood out due to their following advantages:

• high technology makes their operation safe. The device will automatically turn off if there is no water in the tank or if the lid is not tightly closed;
• low noise will not interfere with watching a movie or relaxing;
• a rotating sprayer evenly humidifies the air in the room;
• the built-in hygrostat automatically switches on/off, maintaining a comfortable microclimate and saving energy;
• The presence of an effective filter cartridge allows you to purify the water and avoid the appearance of white deposits on furniture and interior items.

For convenience, many models are equipped with a special indicator that shows the current level of air humidity.

The devices also differ in how they are controlled. Some of them are activated using a rotary knob, while others are activated by pressing touch buttons.

The only disadvantage of ultrasonic devices is their high cost. But small size, high efficiency and economy completely eliminate this disadvantage
