How to reduce humidity in a warehouse - air dehumidification equipment. "Dry" rooms: how to get rid of dampness in an apartment

How to reduce the humidity in the apartment? This question worries many residents of high-rise buildings. V damp rooms being uncomfortable and even dangerous. Fungus quickly settles on their walls, and the air becomes heavy.

An improper home microclimate can provoke problems such as sneezing, congestion, swelling of the nasal mucosa, insomnia, joint pain, weakness. Over time, immunity can significantly decrease, an allergic reaction and chronic respiratory diseases develop. It can even provoke cancer processes in the body.

Humidity standards in a residential area

It is believed that the normal humidity of a dwelling is about 40-60%. In summer and winter, it will change when the heating is turned on and off. A hygrometer will help to measure such indicators. To take readings in an apartment, it is better to use an electronic hygrometer.

For the human body, both dry and too dangerous wet air... And for fans of air conditioners there is a separate reason to worry. It literally draws water out of the air, drying it out excessively. maybe even damp laundry or occasional airing.

Why dry air that is too humid

High humidity leads to the appearance of fungus in the house. Its spores are carried through the air, penetrating the lungs of the inhabitants, guests of the house. This causes rhinitis, asthma. At permanent residence such unfavorable conditions you are provided with chronic rhinitis, migraine, disorders in the work of the cardiovascular system. But there is no need to panic, in most cases you can successfully lower the humidity.

Causes of dampness in the room

There are many sources of moisture in the house:

shower, bath;
washing linen, drying it in the apartment;
aquariums;
plants;
groundwater;
external environment;
breath of people.

Among the main reasons for the increase in humidity are the following:

Natural ventilation is disturbed. This is the most common reason. Often it is associated with replacing windows with plastic ones. Unscrupulous manufacturers can save money and not provide the product with a special ventilation system. Such windows are too airtight and simply do not allow moisture to leave the home. Condensation occurs, mold forms.
Foundation, walls are poorly insulated from moisture. This is due to the violation of the technology for the construction of a residential building. With such errors, the foundation transfers moisture to all walls, and they evaporate it inside the room. Such defects are almost irreparable.
Oddly enough, the third most common reason is salt. It can be added to the foundation in winter so that it becomes durable even in frost. If in concrete walls there is salt, they will be constantly wet. In this case, you need to be patient. After a few years, the walls will completely dry out.
Frequent showers. At the same time, the dampness from the street passes into the house.
Aquariums, home fountains, waterfalls. They are best placed in dry climates.
Drying clothes in the rooms, in the kitchen.
The windows are not facing south. Shady location increases humidity.
Weak central heating in the apartment.
Leaking roof.

Ways to reduce humidity in the home

You can reduce humidity using different means, but first it is important to identify the exact reason for its increase in your home.

High humidity can be temporary, for example during cooking. In this case, ventilation will help. You can use the tools at hand, such as turning on the heater. The main thing is to ensure good circulation and oxygen access. The air flow in the room should be especially powerful if moisture begins to condense on the walls. This can be achieved with a normal draft.
A damp room should be regularly warmed up with a heating device.
Poor ceiling conditions can also lead to increased dampness. It is not easy to drain it. You can try plastering again. In this case, the furniture is taken out so that moisture is not absorbed into it.
PVC windows can significantly restrict air access to a home and provoke dampness in it. When ordering frames, specify the availability of a special ventilation system.
There is modern facilities for the treatment of rooms that reduce humidity (for example, "Stop moisture"). They contain crystals of an absorber, an absorbent. Moisture ends up in special containers.

So, moisture indicators can be improved on their own:

Provide enough good penetration sunlight inside the room. Pull back the curtains regularly. There should be no bulky flowers on the windowsills.
Ventilate more often (three times a day for half an hour). Airing is especially effective in summer and winter, when the air outside is as dry as possible. You can leave the kitchen window open at night.
Provide correct work ventilation. Check if the ventilation window is closed, if the system itself is working.
If it is very damp, you can turn on a household heater. It will quickly heat up and dry the air.
Drywall, wood - building materials that prevent high humidity. Use them for repairs.
Even walls can be sheathed with drywall. Waterproofing plaster will also help to cope with the problem.
Insulate the walls outside. This will help, unless, of course, a flooded basement has not led to dampness.
Install a cooker hood in your kitchen. Turn it on every time you cook. Cover kitchen utensils.
Candles, hair dryers and even indoor plants (which do not require frequent watering) will help dry out the indoor "atmosphere" a little.
If dampness has settled in the closet, iron the clothes with a hot iron.

Air dryer: how it works

We described in detail how to dehumidify the air in an apartment without a dehumidifier, but in some cases this device is indispensable. A dehumidifier is used if the humidity in the apartment is too high, and other methods of dealing with it have not helped.

Its work is based on the absorption of air through the evaporator. The temperature inside the machine is lower than in the room. Moisture condenses on its walls and flows into the container. In this case, the dried stream flows back into the room.
So, this device will help to quickly dry out too humid air in the apartment. The desiccant can be portable or stationary. The latter have great performance. They are wall-mounted, which saves room space. Portable ones have smaller dimensions, therefore their power is lower. When buying, you should clarify what the power of the device is. Choose the device with the maximum power.
You can try assembling a dehumidifier yourself. To do this, watch the video after the article.

We have detailed how to choose a dehumidifier for your home.

Prevention of dampness in the home

For prevention, it is worth remembering the following tips:

After washing, showering, bathing, ventilate the bathroom.
It is not worth drying clothes in the apartment. There is a balcony for this. In modern washing machines there is also a drying function.
Install plastic windows with ventilation.
Discard the aquarium, fountain, or indoor waterfall.
Among indoor plants choose succulents, cacti. They don't need frequent watering.

So, high humidity in apartments is a very common problem. Follow simple tips prevention, and you will not face this extremely unpleasant phenomenon.

Humidity in the house is a common phenomenon, it is formed during washing, cleaning the room, when washing and cooking. But in some houses it is within the normal range, while in others it is increased, in this case the question arises "why does high humidity appear in the house and how to prevent it?"

With its excessive amount, windows, glass and mirror surfaces, stains appear on the walls, often with a bloom of mold, all this is accompanied by a musty unpleasant odor. What should be the humidity at home without causing problems? The norm is considered to be 30-60%, it is measured with a special device - a hygrometer. In addition, it must be remembered that even normal indicators can different reasons it is quite difficult to change and maintain a normal level of humidity, especially in summer, since heating devices dry the air in winter.

Of course, every owner who is faced with this problem wants to know how to get rid of humidity at home, because it causes a lot of inconvenience and, in addition, spoils aesthetic appearance dwellings. Due to constant dampness on the walls, ceiling and in the corners, a fungus can form, which is dangerous to human health, it causes chronic colds, allergies and bronchial asthma... Children are most susceptible to changes in humidity, their immune system suffers from this, and it has a detrimental effect on the home.

How to get rid of humidity at home?

Many factors can affect dampness in a house: weather conditions, the proximity of large bodies of water, building a house on an area with high-flowing groundwater, poor ventilation and irregular ventilation of rooms.

To protect the house from high humidity, mass was invented good ways but in order to achieve maximum effect and eliminate this problem forever, you need to apply these methods in combination. Naturally, such measures will require certain financial costs, but they will soon pay off, since they will help to avoid renovation works and drug costs.

Humidity rate in the house

Before you start fighting dampness, you need to determine the moisture level. As mentioned above, the humidity rate in the house should be between 30-60%, the 45% level is considered the most optimal. Having convinced of its excess, you can begin to work to eliminate it.

The most effective way will be to carry out repair work in a damp room and carry out waterproofing. So, for example, for waterproofing basements, dry building mixture based on cement. In the bathroom, floors are waterproofed using liquid glass... Besides, external walls dwellings are treated with plaster with a cement base, and several such layers need to be made. You can "dress" the walls in a special protective water-repellent coating. These measures will prevent moisture from entering the house.

To reduce air humidity, modern dehumidifiers are used, which are divided into household and industrial ones. Households are used in residential premises, they are very compact and lightweight, so they can be transferred from room to room and installed in any suitable place... Such devices are quiet and easy to use.

Heating devices will be a good option for eliminating the problem, especially in autumn and summer, when dampness on the street more than ever affects the increase in humidity in the room. Frequent use during this period of time will dry out the damp air and prevent mold. But on the other hand, if the house is already heated, such devices can harm health. Today, on the shelves of stores, you can see a large number of chemicals that eliminate high humidity. They effectively fight this problem, but they only act a certain amount of time.

The reason why high humidity appears in the house is greatly influenced by modern double-glazed windows, or rather their poor-quality installation. In order for the air in the room to circulate correctly, the windows must be installed above heating devices, batteries, this prevents the glass from freezing and the appearance of moisture on it. Excess items on the radiator or a very large window sill sometimes interfere with heating window glass... In the first case, you should get rid of the interfering object, and in the second, you need to make holes in a large window sill. Sometimes the reason lies in the glass unit itself, which may be defective and have a defect. The company that installed the window incorrectly is obliged to solve this problem.

Often, the increase in humidity is caused by frequent drying of clothes in the room or malfunctioning pipes in the bathroom, poor ventilation or its complete absence. To eliminate dampness, you need to check the pipes and, if necessary, replace them with new ones, check the ventilation system. Whenever possible, laundry should be dried outside. It happens that things that are not sufficiently dried after washing end up in the closet, this also leads to dampness and the appearance unpleasant odor... Therefore, it is worth drying the laundry as best as possible and preferably in the fresh air.

Oddly enough, but too wet soil in houseplants, it can also contribute to dampness. You can not often and abundantly water the plants without letting the earth dry out properly.

How to reduce humidity in your home?

To the question "how to remove humidity in the house?" there are a lot of answers, the most important thing is to identify its cause, and then choose the most the right ways to eliminate it.

High humidity is typical for old residential buildings in need of major repairs. All of the above measures to eliminate it will not help in this case. There is only one way out - to do complete renovation dwellings using wood and drywall, which are natural materials... Drywall is famous for its ability to absorb excess moisture, and, if necessary, on the contrary, release it. Therefore, it is excellent for regulating indoor humidity.

But still, how to reduce the humidity in the house if its level has exceeded everything allowable norms? The simplest and effective way there will be frequent ventilation of the room, especially after cooking, washing and water treatments... In summer, it is better not to hang windows with curtains, then Sun rays dry the rooms faster. An excellent device that dries air is a fan, traditionally used to cool it. It is impossible not to mention the modern household appliances to reduce moisture. These are expensive air conditioners, special hoods, and simple devices for affordable price... Such devices absorb excess moisture in the air up to optimal level, protect the house from mold and fungus, provide rooms with dryness and warmth, as well as a pleasant smell, which is also important.

How to lower the humidity in your home?

There are other methods for reducing the humidity in your home. These are effective chemical agents produced on the basis of absorbents, moisture absorbers. In the process of using them excess moisture enters the tank. You can use these drugs as needed.

If there is no ventilation in the house, its installation will be required immediately. This work can be done by the landlord himself or by inviting a master. A through hole is made in the wall of the problem room, which is closed with a lattice both inside and outside. A recuperator is pre-installed between the gratings, it will draw out raw air from the room, while leaving heat in the room.

Occasionally, desiccant tablets can help with the problem and can be found at hardware stores.

Before you reduce the humidity in the house to the desired level, you should find the cause of its occurrence, eliminate it and follow the advice to prevent its reappearance.

In the process of dealing with dampness, many forget that excessive dryness of the air is no less harmful to human health, so the main task is not to overdo it and "adjust" the humidity to the optimal level.

It is uncomfortable and sometimes dangerous to live in an apartment with high humidity. In such rooms, a fungus appears on the walls, causing allergic reactions... This microclimate leads to health problems. In the humid air, joints begin to ache, persistent colds suffer, insomnia begins, chronic nasal congestion, general weakness and other unpleasant symptoms appear.

Danger of damp air

The optimum humidity in a residential area is 45-60%. In winter, when the central heating batteries are running, the air in the apartment becomes drier. For human health, both an excessively high content of water vapor and excessive dryness are equally dangerous.

Most often, drying clothes on batteries and poor ventilation lead to an increase in humidity in an apartment.

If the air often becomes damp, sooner or later dampness will appear, from which interior items will suffer, furniture and leather upholstery will deteriorate, plaster will crumble, wallpaper will peel off, and the wooden floor will deform. V damp apartment books and documents deteriorate, food quickly molds. But the worst consequence of dampness is mold and mildew that appear in the corners of the apartment. These microorganisms can ruin health and quickly render housing unusable, especially if the walls are made of wood.

In a damp apartment, the general condition of the body worsens. Excessively humid air is the cause of increased oily skin, greasy hair, skin rashes and allergies. People living in damp areas are prone to lung disease, chronic bronchitis and other respiratory problems. Excessively humid air is heavy, the room smells bad, which makes living in it unpleasant. Any bacteria multiply quickly in a damp atmosphere, so residents are susceptible to dangerous infectious diseases including tuberculosis.

The reasons for the appearance of dampness in the apartment

Dampness in the room can appear on the inside and external reasons... A little experiment is enough to determine where the moisture comes from - from the outside or from the inside. Glass is applied to the wall facing the street for several hours. If a closed area becomes damp, it means that dampness is entering the room from the outside. This is especially common in corner apartments or in houses, during the construction of which waterproofing standards are violated.

If the part of the wall covered with glass turned out to be dry after a few hours, you need to look for the causes of dampness inside the room. It can be:

on the first floor in a house with a basement - raising groundwater or technogenic flooding of the basement;
poor ventilation or its absence - this happens when neighbors close the ventilation shaft;
leakage of plumbing, for example, the bath does not fit tightly to the wall and while taking a shower, water penetrates the floor, accumulating in puddles under the bath;
drying a large number linen in the apartment, which happens when the family has Small child or a bedridden patient;
hobby for houseplants - any indoor flower evaporates water from leaves and affects the microclimate in the apartment.

Sources of internal humidity on the 1st floor or any other, as well as in a private house without a basement, can be:

frequent showering or bathing;
daily wash;
cooking food;
breathing and evaporation of moisture through the skin;
the presence of aquariums in the apartment.

Microclimate correction

It is estimated that as a result of the economic activities of a family of 3, up to 100 liters of water are released into the air every week. It is not surprising that in apartments with sealed plastic windows and poor ventilation, the microclimate changes so much that the walls begin to damp, and black mold appears in the corners.

To reduce the humidity in the apartment, the first step is to check the operation of ventilation and the tightness of heating and water pipes... If something is wrong with these systems, you will have to contact a specialist. If the ventilation and pipes function flawlessly, you can lower the humidity in the following ways:

1. Regularly ventilate the room - just open the vents wide open for at least 10 minutes and the damp air will go away.
2. The bathroom door should be left open at night.

Residents of megalopolises can turn on the air conditioner instead of airing. This will help get rid of dampness in the apartment and prevent gas pollution.

An alpine window will help to dry the air ( supply valve). The device provides feed fresh air to the apartment even in winter. An alpine vent is necessary in a room with poor gas exchange. To install the system, you will have to make a hole in the outside wall... It is covered with heat and soundproof material... You can regulate the level of fresh air supply to the apartment using a damper. The exhaust air leaves the room through natural ventilation... Alpine vents are installed above the windows. The device is not suitable for airing bathrooms, kitchens and toilets - these rooms require forced ventilation.

Alpine window device

Alpine window - appearance inside and outside

The air conditioner effectively reduces moisture and damp odor. The device has a dehumidification function. You can simply use it as a hairdryer for the room air, turning it on to the appropriate mode. But even with routine work the air conditioner dries the room slightly.

A high-quality antiseptic will help remove fungus and mold that have appeared on the ceiling and in the upper corners after the next flood. These products are sold at hardware stores.

The room, heavily affected by the fungus, needs renovation. Wallpaper is being removed from the walls. Sometimes you even have to remove the plaster. All surfaces are treated with an antiseptic and cleaned of mold and mildew. Severely affected areas of the walls can be smeared with creosote. After applying the impregnation, the walls and ceiling must be completely dry before they can be finished. It is better to use wood and drywall for decoration. These materials absorb water when the air is too humid, and emit it in a dry atmosphere.

In winter, the room becomes damp due to the cold. To lower the humidity, it is enough to use electric heaters until the central heating is turned on. They will warm up the room and dry the air. Chemicals for drying apartments are also produced. For example, Henkel implements the Stop Moisture system, which includes an absorbent and an absorbent. Atmospheric moisture is absorbed by the absorber and enters a special container, from where it can simply be poured into the sewer.

There are four main reasons why you need to get rid of the humidity in the apartment as soon as possible:

Causes of dampness

Poor ventilation, nearby sources of moisture, savings on heating and improper insulation are the main reasons for dampness in a private or apartment building.

Insufficient ventilation is the most common cause of high humidity. V apartment buildings, especially in the old foundation, paved ventilation shafts and the grates are clogged, overgrown with debris. As a result, air movement stops. The situation is aggravated by plastic windows, especially cheap samples, low-quality materials for covering ceilings and walls. In private houses, especially self-built ones, the owners sometimes try to save money on ventilation, believing that there are enough windows and doors. This is not true!

If the ventilation system fails, it is not necessary to create a draft, especially in winter - this is fraught with hypothermia. A more expensive but most practical solution would be forced exhaust ventilation as well as amplifiers of an existing system, such as exhaust fans.

Another solution to the problem is to install a recuperator or use a special air dryer. Last device irreplaceable if the cause of dampness is excess moisture (for example, in the bathroom, pool, with an abundance of home flowers).

Moisture source

Sources of moisture in the apartment:

atmospheric precipitation: rain, melting snow, condensation can enter the apartment through a leaking roof, through the pores of the walls and unsealed seams (especially if the wind, improper roof overhang or defective drainage constantly direct precipitation onto the wall);
stagnant water in the apartment: leaking plumbing equipment, swimming pools, baths, aquariums, including those located on the floor below, the same effect is given by a dialed bath or a shower for a long time;
the greenhouse effect from poor ventilation of windows (condensation accumulates on the glass), an abundance of indoor plants, especially if they need abundant watering;
the respiration of people, animals, plants also increases humidity - usually this factor is not noticeable, however, in cramped and / or poorly ventilated rooms it will be noticeable.

Chambo or septic tanks can be located near a private house, which impregnate the grant with moisture. And as a result, the basement becomes very damp, mold develops in it. Another source of moisture in the basement and on the 1st floor is the split blind area (a waterproof coating located around the perimeter of the house). Moisture from the soil and precipitation will seep into the house or basement.

An unheated room is a refuge for dampness. Ideally, the walls of an apartment or house should warm up to at least half the thickness, then the place of condensation formation will go outside (onto the street). In frozen walls, the place where condensation forms is shifted to the warm area, and often is generally located on the surface of the walls from the residential side. The problem is compounded by poor ventilation in the premises.

Housing, where people do not live or that is not sufficiently heated, begins to damp very quickly: the wall decoration collapses on average in two seasons. In addition, in addition to natural wear and tear, the structure loses an additional 5% strength every year due to dampness.

Advice! Vacation home, cottage - no seasonal housing can be left without heating. Hire a person or arrange with a neighbor who will periodically monitor this. If you are visiting for a couple of weeks, do not close the battery valves.

Improper insulation also causes dampness. The main mistakes are an insufficient layer to provide heat, and poor materials with zero vapor permeability.

To insulate an apartment with high quality, you can use one of two options:

The thickness of the layer of polystyrene insulation is within 10-15 cm (and this is important for any region of the Russian Federation).
Use as insulation vapor-permeable material, for example, ecowool, mineral wool. This will make it possible to reliably remove moisture in the walls.

How to remove high humidity

Dealing with humidity will likely require a significant investment of either money or time and patience.

The most reliable ways to deal with dampness are costly. After the rebuild, however, you don't have to worry about drafts or sachets. The methods are expensive, but they pay off with interest:

Replacement of the ventilation system, installation of fans, hoods.
Overhaul, in which it is completely removed old plaster in damp areas. After that, the room is dried and the walls are covered with a fresh layer of plaster.
Replacement and repair heating systems and water supply pipes. The task becomes more difficult if these systems are hidden.
Solving problems with the waterproofing properties of the foundation, walls and roof, which is the most time-consuming and expensive procedure. It is unlikely that it will be possible to cope here on its own, without the involvement of specialists.

Affordable and simple ways to reduce the humidity in the room:

When the weather is dry and warm, you should often ventilate the room by opening the windows.
The bathroom needs particularly frequent ventilation; the hood in this room needs regular cleaning.
You should not dry your clothes in the room, as as a result of this, the air humidity rises significantly. This is permissible only in winter, when the air is dry by the heating system, it must be humidified. In summer, it is better to dry the laundry on the balcony or outside.
When cooking, pots of boiling water should be covered with lids. It is also recommended to close the doors to the kitchen, this will serve as an obstacle for the steam to spread through the rooms in the apartment. Open the windows for slot ventilation in winter or full ventilation in summer, do not forget to turn on the hood. Try to keep the pots from steaming too much (turn off heat).
Reducing the number of indoor plants will help to slightly lower the humidity in the room.
A special dehumidifier (compressor or adsorption) will eliminate high humidity in a separate room.

Advice! The installation of plastic windows, which are equipped with the "micro-ventilation" function, will allow you to regularly ventilate the room, regardless of the season.

Increased humidity is removed if the room is constantly heated at the same temperature.

How to remove the smell of damp

High humidity is often accompanied by a characteristic damp smell. Its cause is a fungus, therefore, in order to eliminate the problem, the infection must be destroyed. Thoroughly rinse away mold stains; if it is deeply ingrained, replace the coating (down to a layer of plaster) if possible. Then treat with a disinfectant, and then a protective one. The products should be marked "antifungal" or "fungicide".

To prevent the mold from divorcing again, in addition to treatment with protective preparations, it will be required in warm, dry weather:

arrange a draft in the apartment, which will provide good ventilation;
hang carpets, bedding, curtains, clothes outside for drying and disinfection in the sun.

Advice! In winter, heaters, household air dryers, air conditioners that are equipped with a heating function will allow you to dry the room.

Folk remedies for dampness in the apartment

Folk recipes also help to dry the air in the apartment:

With the onset of summer, in warm weather, walls that are not covered with wallpaper and are covered with mold are recommended to be treated with the following composition: dissolve half a kilogram in five liters of water laundry soap and then boil the mixture. With the cooled soapy water, coat the wall evenly with a brush and let dry. Repeat the processing several times. Traces of soap suds should form on the wall. After that, apply another compound, consisting of 100 grams of alum, diluted in six liters of water.
Calcium chloride perfectly absorbs moisture. Place containers with this substance in damp places. The advantage of calcium chloride is its reusability. It is enough to dry it (for example, in an oven). Be sure to crush the calcium chloride before use.
Treatment with a mixture of salicylic acid and alcohol will help eliminate mold and prevent the spread of dampness. Dry the walls thoroughly. Then combine one part of salicylic acid and two hundred (200) parts of alcohol. Dilute the mixture with a small amount pure water... Apply this product to black mold spots.

Advice! Replace calcium chloride with charcoal or quicklime.

Use a hydrometer. In the warm season, the optimum humidity will be from 30 to 60%, the maximum - 65. At the end of autumn, in winter, in early spring humidity should vary between 30-45% and not exceed 60.
Provide access to the sun's rays.
Ventilate the apartment; this must be done systematically and efficiently.
Fill cracks in the walls and floor.
Provide quality waterproofing.
Use fans in the kitchen and bathroom, including exhaust fans. Check the draft in the ventilation system periodically. Check the status plumbing equipment, paying special attention to the joints of the pipes.
Systematically inspect the seal on plastic windows, replace it with a new one in time.
By doing overhaul, use mineral-based building materials. This will make it possible to effectively regulate the humidity in an apartment or private house.

You can eliminate dampness in an apartment with simple and available ways... Treating the walls with special compounds will destroy mold and prevent its reoccurrence. Systematic prevention will protect against increased humidity and the formation of fungus.

Air humidity is one of the critical factors affecting human well-being. Well-known fact: when it starts heating season, which leads to a deterioration in the health of people living in it.

But the other extreme - an increased moisture content - is fraught with serious troubles: on surfaces where condensation accumulates, fungus develops, deteriorates Decoration Materials, books, clothes and furniture have bad smell, people suffer from headaches, joint diseases, respiratory disorders.

Dampness is especially dangerous for young children, whose immunity is weakened, and diseases often turn into chronic, intractable forms.

Most often with problems excess moisture residents of private houses collide. Dampness is a frequent guest in housing located near water bodies. The pool located on the ground floor of the cottage certainly enhances the attractiveness of the house, and at the same time because of it.

The problem is typical not only for private houses, dampness is a frequent phenomenon in apartments on the first floors of multi-storey buildings, since basements are flooded during gusts of communications.

Residents of those apartments that are higher suffer from unfinished interpanel seams through which water seeps, and corner rooms often incorrectly insulated, which is why after a short period of time mold and mildew form on the walls.

The design of the ventilation system is of great importance - its poor functioning has the most negative effect on the microclimate of residential premises. Modern plastic windows equipped with airtight gaskets - we make our home impermeable from the inside, and the inevitable vapors simply have nowhere to go.

There can be many reasons for the appearance of excess moisture. In an effective way to combat it is to use special device- an air dryer that can be used in combination with ventilation systems, and independently.

Devices are divided into:

industrial;
household.

The main difference is in the productivity of the systems, which is measured in liters per day. For household units, small or medium power and productivity from 12 to 300 l / day are sufficient. Also, the device intended for use at home is mobile, compact, lighter and more attractive in appearance. There are subspecies living rooms, highly efficient models for a stable humidity level maintenance in a small pool or home sauna.

Devices industrial type, as a rule, are stationary, they cope with a large volume of moisture for a long time.

These dehumidifiers have a wide range of applications. They are used in warehouses, pharmaceutical production, in freezers, water parks, public pools, ice arenas, in the manufacture of hygroscopic materials, construction and.

In the choice of materials for such a device, designers are limited: due to constant contact with water, only waterproof options can be used - plastic, galvanized and stainless metals and alloys. Dehumidifiers differ in design: that is, how moisture will be collected and removed.

assimilation type. It has a low efficiency and is considered the least effective, is not suitable for use in conditions of constant very high humidity, in addition, its performance is influenced by temperature. The principle of operation is based on one of the laws of physics, according to which warm air, unlike cold air, is saturated with a large amount of water vapor. Moisture with warm air it is forcibly removed outside the building, and cold and dry air comes from the street;

condensing type. Such a dehumidifier is based on: water vapor in the condensation chamber cools down, moisture is converted into condensate. A fan is used to drive air saturated with moisture through the chamber. Climatic equipment of this type has a high efficiency, but the lower the air temperature, the lower its performance. Application at low temperatures is irrational;
absorption type. The principle of operation is as follows: air passes through the rotor with an absorbent (this is a substance that absorbs moisture), where it is dried. In the process of dehumidification, one air stream (dry) is directed into the room, the other - hot and absorbing moisture from the absorbent - is discharged outside. This view considered the most effective.

Because household dehumidifier must operate in residential premises on an ongoing basis, one of the most important criteria for its selection is. If it is over 45 decibels, the continuous operation of the device will cause serious inconvenience.

Dehumidifier installation

The mobile compact model is easy and simple to rearrange from place to place, it is convenient where temporary drainage is required - for example, in the basement or during renovations.

The stationary version has a higher efficiency, such a technical solution implies supply electric cable from the meter, drainage, in hidden systems (when the device itself, which makes a lot of noise, is not mounted in a drained one, but in a separate technical or utility room) air ducts are mounted.

floor;
wall-mounted;
universal (with the ability to install on the floor and mount on the wall);
concealed installation.

Work productivity

The dehumidifier is chosen in accordance with the size of the room, while the main requirement for any type is high performance, that is, so that the air acquires the desired parameters as much as possible. a short time.

The golden mean is important here - a powerful device that can lower the humidity level in a short time, and makes a lot of noise. Unit low power in turn, it will work nonstop, at the limit of its capabilities, to cope with the task at hand, which will shorten its service life.

Electronic control makes it easy to set parameters for work.

Recently, almost all manufacturers climatic technology strive to equip their dehumidifiers with a hygrostat. It is extremely useful element: it automatically turns on the device if the humidity readings exceed the norm, and turns off if the air is dry enough.

It is also possible to turn on using the built-in timer, which after a specified time will turn off the device, thereby saving energy.

Also, a dehumidifier can have: given the number of pathogenic microbes accumulated in a damp, warm room, this function is very relevant.

Autorestart function will be useful in those places where there are power outages.
