What device determines air humidity? A device that measures air humidity in an apartment. Indoor air humidity: its permissible and optimal norm in a residential apartment

–device for determining air humidity

Everyone knows that water is the most important element to ensure normal life. It mainly enters the body of animals and humans through food or drink. However, a sufficient amount of moisture is necessary not only for internal organs, but also for the mucous membranes of the eyes, respiratory tract, and skin. Therefore, it is important not only to consume fluid internally, but also to obtain it from the environment. humid air. To determine the humidity level and maintain it at a normal level, use a special measuring device - a hygrometer. It's special laboratory equipment is intended not only to create comfortable conditions for a person. It is also used in some industrial and commercial areas, where many materials: plain and filter paper, fabrics, some types of plastics and other substances, as well as vegetables and fruits are hygroscopic, i.e. change their properties in dry air.

Definition and Application

Also called a hygroscope (from the Greek hygro - wet, and metron - measure) is a laboratory equipment for measuring the relative humidity of air or other gases. Currently there are Various types hygrometers: some measure relative humidity, others – absolute, and others – dew point. Hygrometers are designed in such a way that, with the help of simple calculations and calculations, you can convert the results of the readings of one type of hygrometer into the readings of another. So, for example: according to the hygrometer absolute humidity Relative humidity or dew point can be calculated and determined, and vice versa. In addition, they may differ in types and designs depending on their purpose and operating principle.

History of creation

The problem of air humidity has interested people since ancient times, especially where there is dry and hot climate. To solve it, the most common methods were used: cloth or paper soaked in water, dishes with liquid. But for the first time, Cardinal N. Cusansky tried to determine the level of humidity using laboratory glassware from glass and pieces of wool. Later, the humidity level was measured using stretched threads, a conical vessel with ice, and a leather ball. But B. Saussure is considered the founder of the current hygrometer.

Types of hygrometers:

- a weight or absolute hygrometer helps determine the amount of water vapor in the g/m³ ratio. It is based on a system of U-shaped tubes filled with a hygroscopic substance or special chemical reagents, capable of absorbing moisture from the air ;
- hair hygrometer – special laboratory instrument, the purpose of which is to determine the relative humidity in the range from approximately 30% to 100%. The operating principle of a hair hygrometer is based on the chemical and physical property of defatted human hair, which changes its length with changes in ambient humidity ;
- The most popular measuring instrument is the psychrometric hygrometer (psychrometer). It examines and measures temperature and relative moisture content in the air with high accuracy.

The hygrometer consists of plastic base, two thermometers with a scale, a psychrometric table, a feeder made of laboratory glass. The operating principle is based on determining the difference between the readings of the “wet” and “dry” thermometers;
- a film hygrometer includes an organic film that can stretch and contract as humidity increases or decreases. IN winter time Hair or film hygrometers are most often used.

Hygrometers of the VIT-1 and VIT-2 types, which can be purchased in the online store laboratory equipment in Moscow, are designed to measure room temperature and humidity. The devices contain a chemical reagent - toluene. They differ in the measurement range: VIT-1 (0…+25), VIT-2 (+15…+40). Hygrometers of the VIT-3 type, containing mercury as a thermometric liquid, are most often used in incubators.

In addition to the above types, there are also ceramic, mechanical, electrical, condensation and other hygrometers.

Quality measuring instrument

To determine the quality of measuring instruments, it is important to consider the following characteristics:
- constant value device;
- error limits;
- sensitivity of the device;
- accuracy of the device and the scale used;
- range of readings.

The cause of relapses of allergic and respiratory diseases can be the indoor microclimate: temperature, absolute and relative humidity. Normal values These parameters create favorable conditions for a person to live in an apartment or private house. But how is air humidity measured? The answer is simple: a hygrometer or psychrometer.

Before purchasing a device, you should learn about its advantages and disadvantages.

One of undoubted advantages The device for determining the moisture content in airspace is easy to operate.

Optimal values

Humidity in an apartment is the degree of vapor saturation in the air. It is measured as a percentage of the actual amount of moisture to the maximum possible meaning at the same temperature. Its increased parameters are easy to determine: it appears mold in the corners of the room, a person becomes aggravated chronic diseases, immunity decreases. When indoor humidity is low, wooden furniture quickly deteriorates, and family members experience unpleasant sensations of dry mucous membranes of the nose and eyes. If there is no moisture in the surrounding space, then the dust does not settle on surfaces for a long time, but remains in the air and penetrates the bronchi and lungs.

The purpose of the room determines optimal parameters humidity. The norm is expressed as a percentage:

• living room – 50-60%;
• bedroom – 45-50%;
• children's - 50-60%;
• office – 40-45%;
• kitchen and bathroom – up to 60%.

The values ​​obtained during the measurement process are influenced by many factors - time of year, power of heating radiators, region of residence.

Experts operate with two types of humidity:

• relative;
• absolute.

The last value shows how much moisture is in a cubic meter (how the air in the room is measured). At home absolute indicator practically not used.

Humidity parameters can be determined using indoor plants. If the leaves curl and turn yellow, they are often inhabited by harmful insects, then the air in the room is very dry. When flowers appear brown spots, and the roots begin to rot, this means that there is excess water content in the surrounding space.

Relative air humidity is measured using instruments that are convenient to use by a person without special skills in working with complex devices. This parameter is quite sufficient to determine the moisture content in the surrounding space.

Types of devices

At home, measure air humidity different ways, but the most objective values ​​are obtained when using special instruments: a hygrometer and a psychrometer.

Air humidity is measured using a hygrometer, the principle of which is based on recording variables when the concentration of water molecules in the surrounding space increases or decreases. Under such conditions, changes physical parameters(density, mass, length) structure of the material used in the measurement process and actively absorbing moisture. The results obtained will characterize the degree of saturation of the surrounding space with water vapor. Before measuring air humidity using a hygrometer, keep in mind that the values ​​will be approximate.

In specialized stores, hygrometers are presented in a wide range. They are:

• hair;
• by weight;
• condensation;
• electrolytic;
• ceramic.

For household use No special precision instrument is required. It is easy to determine relative humidity with a hygrometer, but there are also performance characteristics device.

Before measuring air humidity, you need to consider the features of using a hygrometer:

• You must always ensure that the dampening material is wet and clean;
• Do not place the device near air conditioners and radiators.

The principle of operation of a hygrometer is based on comparing the readings of a thermometer in contact with wet material and a thermometer recording values ​​in a real environment. The results are determined on a conventional graduated scale. The difference in parameters is checked against the data of the psychometric table, regardless of which device the values ​​were obtained from.

To measure air humidity using a psychrometer, you need to understand the principle of its operation. When liquid evaporates, the temperature of the surrounding space decreases. The more intense the evaporation, the cooler the air becomes, which is determined by the device. This process is influenced by a complex of factors:

• water vapor concentration;
• speed of air flow in the room.

Taking into account the temperature difference between the wet material and the air, the rate of evaporation can be determined. If the device is located near a window or fan, the obtained values ​​will not be accurate due to the circulation of flows.

Relative air humidity is measured using the following types psychrometers:

• stationary;
• remote;
• aspiration.

The latter are considered the most accurate and reliable devices. It is very easy to measure air humidity using an Assmann psychrometer - the device is equipped with a protective housing. Therefore, the obtained values ​​are not affected by air flow speed.

Handy methods

One of the informative methods by which you can determine the humidity in an apartment is observing a burning candle. In a room with a normal microclimate, its flame is strong and even. When there is excessive moisture content in the surrounding space, the candle flame fluctuates from side to side, and scarlet inclusions appear on its edge. Do not forget that air humidity is measured in this way with the windows and doors closed.

You can determine the water vapor content using a regular glass of water. After placing it in the refrigerator, you should wait about an hour. During this time, the temperature of the liquid will drop to 3-4°C. Relative air humidity is determined after removing the glass and observing the evaporation processes taking place:

• the walls of the vessel remain fogged - the moisture content is within normal limits;
• the walls are dry - low humidity air;
• condensation flows down - there is a lot of water vapor in the surrounding space.

If your laundry dries quickly in your room, you should consider purchasing a humidifier. And dampening of fabric items indicates an excess amount of moisture in the room.

It is up to the owner of the premises to decide which device to use. People who care about their health and strive to maintain all microclimate parameters within normal limits equip their apartment with real home weather station. Manufacturers have launched the production of devices equipped with a barometer, hygrometer and thermometer. Of course, such a device cannot be cheap. But all costs quickly pay off - the owners of the premises save on medicines for family members, they do not need to change wallpaper damaged by fungus and upholstered furniture.

Important indicators that determine the microclimate of an apartment, house or any other room include temperature and moisture content in the air. And if the temperature can be approximately guessed by sensations, then for the second parameter you will need a special device to determine air humidity.

If there is too much vapor in the air or, conversely, not enough, this greatly affects the immune system. To avoid health problems, special devices are used to measure humidity.

In this video you will learn what a psychrometer is

There are two types of humidity:

1. Absolute. Shows the amount of water in g/mᶟ.
2. Relative. To calculate its value, you need to divide the current humidity by the maximum possible, then multiply the resulting value by 100. Relative humidity is measured as a percentage. To obtain exact value, you need a device to determine the relative humidity of the air.

Lack and excess of moisture

For people, animals, plants and even some materials, excess moisture is just as destructive as its lack. If there is a lot of moisture in the room, then the first thing you can notice is on the glass of the window, which begins to sweat a lot. From such excess moisture, the air and things acquire a damp smell, and mold forms on the walls. It provokes various allergic reactions that reduce the body's immune defense.

Lack of moisture can lead to dehydration, as sweating increases indoors. In addition, the amount of dust in the air sharply increases, and this can cause allergies.

Measuring instruments

The accuracy of the readings depends on which device is used to determine air humidity. Exist different types devices:

1. Hygrometer. You can most often find a hygrometer on store shelves. electronic type, it is ideal for simple monitoring and is inexpensive. But there is a significant drawback - low accuracy of readings; on average, its error can reach 20%. It is considered more accurate mechanical device, but it will cost several times more. You can find hair and film hygrometers. The peculiarity of these two varieties is that both will give accurate readings only when low temperatures, and in the hot season you shouldn’t expect accuracy from them.
2. Psychrometer. According to experts, this particular device is considered accurate. The operating principle of the device is as follows: the psychrometer has two thermometers and a special table. On one of the thermometers there is a can of liquid, which should be wrapped in a rag. One end of the rag should always be in a cup of water. To obtain the result, the difference between these thermometers is taken for calculation and the relative humidity is determined using a psychrometric table. The psychrometer is very convenient to use, as it allows you to monitor two indicators in a room at the same time.

A thermometer can measure air humidity

Of the two types, each person must choose for himself which device is right for him. Perhaps someone will choose a more accurate one, while others will choose a device that is more convenient to use.

From this article you can find out what a device for measuring air humidity should be like. The text discusses the main types of devices designed to control climate by measuring water vapor in the air. Described here existing types devices, their technical and operational features, rules of use.

Humidity affects the condition of furnishings, household appliances and human well-being. The presence of water vapor in a certain amount in the air depends on the following factors: technogenic impact, climatic features region, the state of communications and the building as a whole, as well as the operating conditions of the premises.

Humidity standard for healthy person the figure is considered to be 40-60%. To create optimal conditions, special devices are used. Depending on the needs, these can be dehumidifiers or humidifiers. Air humidity meters are used to coordinate the operation of these devices.

Note! There are air conditioning systems with automated function moisture level control. This type of equipment independently measures air parameters and adjusts them to the norm.

How is air humidity measured in residential premises?

You can measure the amount of water vapor at home using available means, for example, fir cone, whose scales open if the room is dry, or monitor the condition of the condensation by first cooling the container with water.

The method, which involves the use of a container, is based on how condensation behaves on cooled surfaces and at what speed it evaporates. A medium located in a closed space, subject to balanced processes of condensation and evaporation, is in a state of saturated vapor. If the amount of moisture in saturated steam is close to the concentration of water vapor in the air of the room, then the evaporation process will be difficult. This will indicate the presence of excessive moisture in the room.

How to measure air humidity in an apartment using a glass:

1. Fill a glass container with water. Not only a glass, but also a bottle or jar is suitable for these purposes.
2. Place the container in the refrigerator for a couple of hours.
3. After this, take out a glass and measure the temperature of the water. This indicator should not exceed 50°C.
4. The control vessel should be placed in the room, away from heating appliances.

Note! It is imperative to note the time to observe the behavior of the condensate. This will take from 5 to 10 minutes.

If the condensation accumulated on the walls dries within the indicated time, it means the room is dry. Wet glass indicates that there is something in the room optimal conditions with a sufficient level of humidity. If the drops of condensate are large and flow down the walls of the vessel in streams, this indicates an increased amount of water vapor in the room.

What instruments are used to measure air humidity?

More accurate data can be obtained using special devices. There are several types of devices available for these purposes. The most primitive instruments that measure indoor air humidity are called hygrometers.

• ceramic;
• electronic;
• weight;
• electrolytic;

• condensation;
• hair;
• film

Each type of listed devices operates due to a certain operating principle, for example, design feature hair device is the presence of tubes U shape. Condensation hygrometer considered the most accurate. It takes measurements with minimal error.

• station;
• remote;
• aspiration.

The station version of the device is the most popular of them. Its design includes a pair of thermometers mounted on a tripod. A dry thermometer shows the air temperature in the room; a wet thermometer is wrapped in a cloth, one end of which is lowered into a reservoir filled with liquid (water).

Note! Do not place the tip of a wet bulb thermometer directly into the tank, otherwise it will indicate the temperature of the water rather than the air masses circulating above it. There should be a distance of at least 30-40 mm between the end of the device and the container.

Classification of instruments for measuring relative air humidity (hygrometers)

The state of human health depends on a large number of factors. An important role in this is played by the cleanliness and humidity of the air. If there is not enough moisture in the room, the mucous membranes respiratory tract will dry out, as a result of which a person may develop diseases associated with the activity of harmful bacteria.

The most simple hygrometers suggest the use of a table of relative air humidity; from the temperature indicated in it, you can get an idea of ​​​​the state of the microclimate in this moment. More advanced models have a set of microcircuits that independently perform calculations and display the result electronically on the screen.

In addition to structures traditional type, offer modern market allows you to buy humidity meters with additional functionality. Such devices also display other data:

• air temperature in the room;
• current time and date;
• atmospheric pressure level.

Note! Some types of devices are equipped with an indication system. It informs the owner if the microclimate of the room is outside the normal range. This feature allows you to notice the problem in a timely manner and fix it.

Features of hair room air humidity meter

This type of device is used to determine the humidity level within 30-80%. The design of the device consists of several elements:

• metal frame in the form of a frame;
• measuring scale (the step of each division corresponds to 1% humidity);
• human hair (low-grease);
• screw-adjustable pointer;
• a pulley designed to allow the free end of a hair to be thrown over with a weight attached.

A hair hygrometer is a type of measuring device designed to determine air humidity, the principle of operation of which is based on the hygroscopicity of human hair, in other words, the ability to lengthen or shorten under the influence of moisture. When the humidity in the room decreases or increases, the hair tension weakens or, on the contrary, increases. As a result, the pulley turns and moves the arrow pointing to the scale. Due to this, it is possible to determine the exact humidity indicator environment.

The hair type hygrometer has a significant advantage over other devices. Its readings cannot be affected by air temperature, as is the case with electrolytic models. It does not require electricity to operate; the hygrometer operates through mechanical processes.

What device measures air humidity in its absolute value?

In order to identify the current level of humidity in a room, you need to know two values: the relative humidity indicator and the absolute value. Percentage between them constitutes the desired parameter. Therefore, it would be useful to know the name of the device for measuring air humidity in its absolute value and the principle of its operation. A weighing hygrometer measures the amount of water vapor contained in one unit of air (1 m³).

The device includes several U-shaped tubes that form a system. Inside them there is a hygroscopic substance that absorbs moisture from air masses. A certain volume of air passes through the system, which is taken from one point. This design allows you to determine the mass of air at the inlet and outlet, as well as its volume. The absolute value is determined by mathematical calculations.

Interesting fact! The study of water vapor as one of the components of air began in the 16th century. The author of the first scientific work dedicated to this topic was J. Port. It was published in the 17th century. After heyday steam engines in the 19th-20th centuries. water vapor again interested scientists. After serious research in this area, the fourth International Conference was held in 1963, dedicated to its physical characteristics.

Characteristics of ceramic instruments for determining air humidity

Ceramic devices are a commonly used type of moisture meter; moisture meters of this type are simple and mechanical. The device is made of ceramic mass, which can be porous or solid. It contains metal elements. The ceramic mass has electrical resistance, and room humidity has a direct impact on the level of this resistance.

In order for the mechanical design of a room humidity meter to function properly, certain metal oxides must be included in the ceramic mass. Silicon, clay and kaolin are used as a base.

Features of condensation devices for measuring air humidity in an apartment

A condensation hygrometer makes it possible to obtain the most accurate indicators reflecting the climatic comfort of the room. It is for this reason that many consumers will choose to buy this type of indoor air humidity meter.

The design of the device consists of the following elements:

• metal box;
• thermometer;
• rubber bulb;
• heat-insulating gasket;
• front wall;
• ring.

The condenser type of humidity and temperature meter analyzes the amount of condensation that forms on the surface of the glass. A small beam of light is directed onto a special mirror that is cooled, causing drops of water or ice crystals to appear on the surface. Due to electronic thermometer built under the mirror, the temperature is determined. The device converts the received data into an indicator that displays the level of relative air humidity.

Note! Consumers can select and buy a device for measuring air humidity of an improved modification. Such models are equipped with a display designed to display readings. The advantage of such devices lies in long-term stability. The devices are characterized by a long service life and an increased range of action (the device covers from 0 to 100%).

Features of electronic temperature and humidity meters

Possibilities electronic device to measure indoor air humidity, they allow you to measure changes in the concentration of the electrolyte that coats the material with electrical insulating properties. These materials include plastic and glass. Some device options have an automatic heating function. They measure the dew point.

In addition, temperature fluctuations are taken into account, since it can affect the operation of the device, albeit insignificantly, therefore the devices are equipped with thermometers to facilitate their operation.

Electronic modifications are precise in measurements, which mechanical designs cannot offer. The percentage of errors in their work is extremely low.

Consumers can buy air humidity meters that have different operating specifications:

1. Air conductivity measurement - devices determine the value of absolute humidity. To calculate relative humidity, you need to measure the temperature.
2. Optoelectronic measurements - devices measure dew point using a cooled mirror. It is frozen, after which a process of gradual heating occurs.
3. Resistive measurements - the operation of the devices is based on the effect of changes in the conductivity of polymers or salts under the influence of humidity levels.
4. Capacitance measurements - during operation, the unit monitors changes in the capacitance of the capacitor (polymer or metal oxide).

How to measure air humidity at home using a psychrometer

Psychrometers are designed to determine relative humidity. The device operates by physical properties liquid, in particular its ability to evaporate. This process creates a difference between the wet bulb and dry bulb temperature readings. During evaporation, the liquid loses some of its energy, causing a decrease in temperature. This change is detected by the thermometer.

The psychrometer design consists of a pair of alcohol or mercury psychrometers. As the liquid evaporates, the wet bulb thermometer cools. The lower the air humidity level, the faster the liquid evaporates. In turn, the drier the air, the lower the temperature indicator displayed by wet thermometers. Due to this, there is a difference between the readings.

Note! Regardless of the device used to measure air humidity, it should not be installed near radiators or air conditioners, otherwise the measurements will be inaccurate. In addition, you need to monitor the condition of the material for moisture. It should be clean and wet.

Some psychrometric hygrometers require certain temperature conditions. For example, the lowest permissible temperature limit for winter is -15°C, and for summer the highest temperature limit is 40°C. The measurement range depends on the temperature, the air humidity table with environmental indicators can be used as a guide.

Measuring range according to air humidity table:

Air humidity level in a room: how to measure the amount of water vapor

The process of measuring humidity using a psychrometer is very simple. In addition to this value, the device also measures the temperature parameter. As a rule, along with alcohol thermometers mounted on a plastic base, the manufacturer places a psychrometric table of relative air humidity, which allows you to read the readings.

There is one important condition, ensuring accurate operation of the device. The psychrometer is extremely sensitive to drafts, so it is recommended to create conditions under which the speed of movement of air masses in the room should not be more than 1 m/sec, otherwise the difference in readings taken from thermometers will be much greater than in reality, which will lead to inaccurate result.

The psychrometric table of air humidity is used to interpret the psychrometer readings. The first column contains temperature indicators dry thermometer. The first line displays the difference that occurs during the measurement process between the readings of both thermometers. To get the actual level of relative humidity, you need to take the value that is formed at the intersection of the corresponding parameter from the first column and the first row.

The Assmann psychrometer is an improved modification of the device, which performs measurements more accurately and is not afraid of drafts, since its thermometers are protected from heat and direct contact sun rays thanks to the metal body.

Home weather stations for convenient microclimate control

Consumers who pay increased attention to their own health and strive to bring air parameters closer to optimal value, manufacturers of climate control equipment offer to buy an electronic hygrometer - a humidity and temperature meter and a barometer in one device. A design with similar functionality is capable of fully controlling the microclimate. However, the price of such devices is quite high.

Such devices not only have a large number of functions, but also have decorative design. They can optimally fit into almost any room interior. You can also find unusual combinations on sale, for example, baby monitors with a built-in hygrometer. These devices are optimized specifically for children's rooms. There are also models with Wi-Fi function. They connect to the World Wide Web and display weather forecasts and other data on the display.

A hygrometer will become an indispensable assistant in maintaining optimal climatic conditions in the house. Its readings help to adjust the operation of the humidifier or bring the level of water vapor in the air back to normal.

Air humidity is one of the main indicators favorable microclimate in the apartment. This value determined, as a percentage of the number of water molecules in a cubic meter of air at certain temperature, to their maximum quantity in saturated steam under the same conditions.

Air humidity in a living room according to GOST 30494-2011 should not fall below 30% V winter period and exceed 65% in summer.

Support the humidity level in the apartment is optimal level necessary to create favorable conditions human life activity. Excessive or insufficient humidity air may reduce immunity, worsen heat exchange and lead to acute and chronic diseases. Carry out regular control relative humidity in residential areas is helped by measuring devices.

Electronic hygrometers are multifunctional and mobility. You can install them anywhere in the room, modern design will not damage the case general interior premises.

Important: Many models of electronic hygrometers are equipped with a memory function and can record changes in readings over a certain period of time.

Mercury thermometer

• Medical mercury thermometer;
• Thin cloth;
• Water;
• Stopwatch or watch;
• Psychrometric table (can be found on the Internet).

Measurement temperature in the room is carried out at first dry bulb thermometer, then wrap the mercury tip wet cloth and through 10 minutes they take a second measurement. Calculate difference between the readings and find the relative humidity value using the reference table.

In a vertical column the table shows dry bulb readings, and the top horizontal line the value of the temperature difference. In the cell at the intersection of the lines of two readings one finds percentage indicator of humidity in the room.

Self-measurement of air humidity

If the concentration of water vapor in the room approaches the concentration of moisture in saturated vapor, then evaporation will difficult. This sign indicates on increased moisture content in room.

To conduct an experiment (determine humidity) necessary:

• Fill a glass vessel(glass, jar, bottle) water;
• Place a container of water in the refrigerator for 2-3 hours;
• Measure the water temperature, it should be no higher than 50C;
• Place control vessel far away from heating devices;
• Time it monitoring condensate evaporation ( 5-10 minutes).

  When dry indoor air, condensation on the walls of the vessel will evaporate after a specified period of time. If the glass remains wet, then the room has an optimal level of humidity. On increased The moisture content in the room air is indicated by large drops of water that collect in streams and flow down the smooth surface vessel.

  How to increase humidity in an apartment?

  

  As you know, dry air harmful for human health. To improve microclimate in the apartment - can be set household humidifier air. Modern devices According to the method of preparing and spraying water, there are nozzles, steam and ultrasonic.

  Nozzle or traditional humidifier sprays water using a built-in fan. Its advantage is self-regulation evaporation rate.

  Steam appliance works on the principle electric kettle, the steam temperature reaches 600С. The most popular model is ultrasonic humidifier, which sprays water vapor in the form of fog. Quiet, compact and safe device suitable for any room.

  For maintaining humidity in an apartment at an optimal level it is necessary to fully ventilate all rooms, separate houseplants and water and spray them regularly, install a large aquarium.

  In winter, when the air in the rooms becomes dry, you can place vases with water on flat surfaces, and hang humidifiers in the form of small containers.

  What to do if the apartment is too humid?

  

  Excess moisture in the apartment may cause to the formation of mold and mildew on walls and furniture. The presence of spores of toxic microorganisms in the ambient air negatively affects human health.

  Therefore, it is necessary to take in time:

  • Place on window sills and sanitary facilities moisture absorbers;
  • Check the draft in the exhaust ducts of the bathroom, bathroom and kitchen;
  • Increase the area of ​​heating devices;
  • Provide air conditioning in optimal mode;
  • Turn on while cooking.

  To reduce the humidity level in the apartment, you can use a household dehumidifier air. Inside the body of such a device there is a cooled plate on which moisture condenses. After heating, the air enters the room again. Performance varies among different models from 12 to 300 l/day.

  Advice: To select a dehumidifier based on performance, you need to multiply the area of ​​the room by a factor of 0.7.

  Excessive or insufficient moisture content in the air of a residential area adversely affects human well-being and health. Regular control relative air humidity using one of the types of household hygrometers allows you to maintain the microclimate in the apartment at an optimal level.

  To create comfortable conditions, it is necessary to carry out preventive and emergency measures to humidify or dehumidify the air.
