Humidity in the apartment: the rate indicator for premises

The article discussed in detail such a thing as the humidity in the apartment: the rate of this index for residential buildings for different purposes, have registered the guest, the consequences for the person, resulting from abnormalities in one or the other side. The text describes alternative methods for measuring moisture level and devicesDesigned for this purpose, as well as the recommendations to maintain optimal climatic conditions.

Humidity in the apartment: the norm water content for comfortable living conditions

The optimum humidity level - this is one of the components, ensuring a comfortable climate for human habitation. And for each of the premises, depending on its purpose, provided its own microclimate. Most people care about temperature and quality of air in the house and forget about this one. But it is the number of molecules of water (steam) as a part of the air affects the perception of the human body temperature, to the safety of the situation in the room and the condition of the plants.

Note!The conventional average normal air humidity in the flat should be at a level of 45%. It can vary depending on the type of room and operating conditions.

The deviation from the norm is possible, as in the winter season and during the warm season. In both cases, a lack or overabundance of moisture leads to the deterioration of human health, plant health and damage to furniture, decoration, etc.

What should be the humidity in the apartment (averages for the main premises):

type of lodging	humidity level,%
Dining room	40-60
Bathroom, kitchen	40-60
Library and work area	30-40
Bedroom	40-50
nursery	45-60

Spaces such as the kitchen, bathroom and toilet will always have an elevated level of moisture, so the norm for these rooms are higher than for other buildings.

What are the consequences entail a deviation fromstandards of humidity in the apartment: Overdried air

When the battery included, indoor air becomes overdried. As a consequence, occupants mucosa is irritated throats and nasal cavity. There is a drying of hair and skin. When violating rules humidity in the dwelling static electricity is formed, lifting the dust particles in the air. This process can be the basis for the spread of germs and dust mites.

Excessive dryness of the premises entails many negative consequences:

• decreased elasticity of the skin, hair and nails - as a result, there dermatitis, peeling, micro-cracks and premature wrinkles;
• drying of the eyes - there is redness, itching and unpleasant sensation of a foreign body ( "sand");
• thickens the blood - because this slows down the circulation of blood flow, the person has a weakness, headaches. A decrease in efficiency, the heart is exposed to increased stress and wear out faster;
• increases the viscosity of intestinal and gastric juice - work considerably slows down the digestive system;

• dryness of the respiratory tract - as a result of the weakened local immunity, increases the likelihood of colds and infectious diseases;
• reduced air quality - in the composition of the air mass concentrates a large number of allergens that at normal air humidity bind water particles.

Aboutratite Atteof!Suffer from a lack of moisture the plants and animals are to the apartment. Reduced service life of wooden furniture and finishes, they fade, covered with cracks.

What are the implications implies above normal humidity

The overabundance of water can also be dangerous to humans, so many people are thinking, what humidity Air is considered normal in the apartment and how to keep the climatic conditions in this index. Increased content of water vapor in the room becomes an ideal breeding ground for fungi, mold and harmful bacteria.

In such circumstances, there is a lot of problems:

1. Increases the frequency and severity of respiratory disease - diseases such as bronchitis, rhinitis, allergy and asthma become chronic, difficult to treat.
2. The microclimate in the rooms is no longer acceptable for life - people feel damp or stuffiness in the rooms.
3. Lost feeling fresh - separation breeding of pathogenic organisms cause odors.
4. Increases the drying time to wash clothes.

Increased humidity indicator of the apartment is also harmful to environment. Plants begin to rot on the ceiling and walls appear mold, wood surfaces exposed to deformation changes. Books and other paper products are changing the structure.

What should be the humidity of the air in the apartment: According to GOST standards

Humidity can be relative or absolute. To create a comfortable climate in the house to calculate the optimal value. GOST 30494-95 is regulated rate, indicating a normal humidity in the apartment should be.

Relative humidity is expressed as a percentage ratio of the two values:

• optimal rate;
• permissible value.

Permissible value - a border that is not harmful to human health, but it can have a negative impact on overall health, mood and reduce performance.

Please Attention!If in relation to the bedrooms, children's rooms and other areas where a person is on for a long time, provided certain rules that strictly adhere to the normal humidity in the room kitchen, bathroom, hallway and bathrooms not necessary. These rooms are considered auxiliary.

The unit of measure is taken actual absolute humidity content of steam in 1 m³ of air. For example, in one cubic meter of air may contain 13 g water. In this case, the absolute humidity is equal to 13 g / m³.

To get the relative humidity is required to perform certain calculations. It requires two parameters:

• maximum possible water content in 1 m³ of air;
• the actual amount of water in 1 m³ of air.

The percentage of the actual data to the maximum possible figure will be relative humidity. For example, in 1 m³ of air at a temperature of 24 ° C can accommodate a maximum of 21.8 g of liquid. If in fact there will be present 13 g of water, the relative humidity is equal to 60%. For convenience, you can use a special table of absolute humidity, which contains auxiliary data.

Norm humidity in the room according to GOST

Rate prescribed by the guest, not only depends on the destination premises, but also the time of year. For warm season provided 30-60%. The indicator of the relative humidity in the room is 60 percent, and the maximum will be 65%. For some regions where during the summer months are accompanied by high humidity, the standard value may be increased to 75%.

For the cold season standards for relative humidity in the room equal to 40-45%. In this case the maximum value is 60%.

For interior plants and also provides guidelines:

1. Furniture and antiques thrives at 40-60%.
2. For home appliances recommended humidity between 45-60%
3. Books and other paper products require 30-65% humidity.
4. Standards for green areas depend on the type of plant. Tropical greenery, you need a high level of humidity - 80-95%, subtropical limited to 75-80%, and for all other suitable component within 40-70%.

Note!The following table shows how the relative humidity is interconnected with the comfort and health. From its level depends on how comfortable feel in the house of harmful elements and how to proceed negative processes outside the norm humidity.

Comfort zone harmful to human cells:

Type of harmful effects	Humidity%
100	90	80	70	60	50	40	30	20	10
bacteria	1	2	3
fungi	4	3	2	1
viruses	1	2	3	4
dust mites	5	4	3	2	1
Allergic reactions, asthma attacks	5	4	3	2	1	1	2	3	4	5
The process of forming ozone	1	2	3	4	5	6

In the table "6" indicates the maximum value of the impact, "1" - a minimal effect on people.

humidity norm in an apartment for a child

child's immune system is not as efficient to cope with the negative impact of environmental factors, like the body of an adult. Children overheat much faster or peremerzayut easily catches a cold, suffer from infectious diseases and heavier they are transferred.

For this reason, it is important to maintain optimum humidity in the apartment for a child, especially in his room, where it is necessary to create conditions for the maintenance of immune toddler forces.

In the children's room in any case air must be dry. Such an atmosphere provokes intense moisture loss by the body baby. Drying of the mucous nasopharynx leads to their inability to resist viruses and infections. The child may appear itchy eyes and flaking of the skin. For a child is considered to be the optimum humidity in the apartment between 50-60%.

According to Dr. Yevgeny Komarovsky value of the normal air humidity in the apartment can be increased to 60% for a healthy baby and 70% for a child suffering from an infectious disease. The higher the humidity, the less intense drying of the mucous membranes occurs.

Indicators of normal humidity in the apartment for the child's body in the winter are the same as for the warm season. However, there is a caveat: maximum air temperature in the room must not exceed 24 ° C. If the room is hotter, the humidity is 60% of it will make the tropics. In practice, in the heat of high humidity in the apartment more difficult to endure than in the cold season.

Important!Exceeding 24 ° C in a child's room may lead to overheating of the organism baby. As a result of accelerated drying of mucous and fluid loss.

How to achieve the optimum humidity in the apartment

The main factor that has the greatest influence on the humidity is temperature. The heat in the room, the more water is able to absorb air. However, when calculating the relative humidity should be remembered that at high temperatures the liquid volume in the same amount of air will be smaller. This nuance may advantageously use a very fresh and by ventilation are provided to maintain optimal parameters humidity norms, the air outside in winter.

Moisture is absorbed:

• appliances intended for heating;
• interior items such as toys, upholstered furniture, carpets;
• air conditioning.

As a small source of moisture may be considered plant and an aquarium, tanks filled with water, the wet clothes, the current roof or pipe.

How to determine the humidity of the air in the apartmentwithout instrument

To determine how much deviated humidity level in the house, you can do without a special instrument and take advantage of:

• a glass of water;
• Assman table;
• fir cones.

To determine the relative humidity by using water glass filled container must be cooled in a refrigerator to 5 ° C. It will take about 3 hours to water and the vessel reached the specified temperature. After that, the glass is placed at a distance from the battery to the table. Within 5 minutes on the vessel walls formed condensate.

Further results will depend on the behavior of the condensate:

1. After a few minutes the glass is dry - humidity index is lowered.
2. Condensation on walls disappeared - the room has a normal climate.
3. According to the vessel flowed streams of drops - an overabundance of moisture in the air is observed.

Fir-cone can serve as a device for the measurement. It should be put away from heaters and a few hours to check the status of scales. If the air is too dry, bump revealed, when an excess of moisture - flakes tightly shrink.

All of these tools are only indirectly indicate a problem. To accurately determine the climate in the room is better to buy a humidity sensor.

Useful advice!The primary symptom of dry air are dry tips of plants. Also insufficient moisture level can be determined by synthetic clothes, which in such circumstances emits electrical charges.

Features of the application of temperature and humidity sensor

For the measurement of humidity, you can use special devices called sensors or hygrometers. Independently apparatus converts the received data and outputs the result as a percentage.

Many people are looking for a solution, wondering how to remove the humidity in the apartment. For climate control in the bathroom and other rooms with the excess moisture using exhaust fans. They prevent the formation of condensation on the walls and on the floor.

For residential premises it is recommended to purchase a humidifier, if there is lack of moisture on a regular basis. It will also need to buy an additional humidity sensor for the fan and humidifier, if not by design devices themselves.

The operation of the humidistat or thermostat sensor lies action principle. The device opens and closes the contacts, in response to the amount of water vapor in the air. Thus, the operation of the fan or humidifier becomes automated. The device is activated only when it is needed.

Humidity control in the apartment: how to reduce / increase the amount of vapor in the air

To control the amount of steam a variety of methods used in the air, including the means at hand. Their combination allows to achieve a certain result.

How to get rid of the moisture in the apartment:

1. Ventilate the room at regular intervals.
2. Install exhaust fans such as where they are needed.
3. Purchase or climate system Air Dryer.
4. To make timely repairs to the house (service plumbing and running water).
5. Use heaters and air conditioners.
6. Unsubscribe from drying clothes indoors.
7. Install a powerful hood in the kitchen.

Useful advice!To hygrometer indicators were significant, it is recommended to install the device in the back of the room to eliminate the influence of drafts and other factsHur.

How to increase the humidity in the room:

1. Buy table fountain or aquarium (if none of the household does not have asthma).
2. Minimize the use of air conditioners and heaters.
3. Hang wet towels on the radiator.
4. From time to time the water spray sprayed, thereby saturating the air with moisture.
5. Regularly do wet cleaning in the house.
6. To plant as many indoor plants as possible.

There are many devices that will achieve a particular result, depending on the needs. They are selected based on the microclimate in the house. Before their purchase is recommended to ascertain the humidity parameters. To do this, take measurements over several days.

Maintain optimum humidity in the house is possible by means of special devices - humidifiers. This category includes a plurality of climate equipment modifications: conventional, steam, ultrasonic devices. "Sinks" air and climate systems - more sophisticated versions of these devices are equipped with a hygrometer, timer and other useful additions. In the fight against mildew help ultraviolet lamp.
