Control the microclimate. Relative humidity

Recently, we are increasingly convinced how dependent people from the surrounding nature. They also disrupted the ecology of a response in the form of global warming, climate change and other disturbance of the normal (usual) conditions of existence has a negative impact on health is not separate individuals suffering from one or another ailment, and almost all people inhabiting the planet Earth.

The Urgency of this problem is confirmed by the reports of the world Health Organization, statistical indicators of somatic and infectious diseases, reduced life expectancy, but also a manifestation of other negative trends on a wide range of medical statistical data. And all this with the modern level of development of medical technologies and vast experience in the treatment and prevention of almost all common human diseases.

To Solve at least part of the problem by creating a favorable microclimate of their homes and workplaces. To adjust the temperature level established health standards or simply make it cozy for the person we have learned a long time ago. But besides temperature, there are many other criteria for indoor climate. Among them, the relative humidity plays an important role. The amount of moisture in the air affects the health of people, their efficiency and ability within a specific space to get a full good night's sleep.

Low humidity adversely affects the skin and mucous membranes. Their drying can lead to the appearance of microcracks, and this open the way for penetration of various infections. High humidity causes the feeling of heaviness adversely affects the cardiovascular system and other systems of the human body.

The Optimum moisture content of the air in the apartment has a clear limit. For classification this indicator you can use the following rules:

- from 20% or below – complies with the extremely low humidity;

- from 30 to 40 percent - just low;

- from 40 to 55 % is the most optimum moisture content;

- from 60 to 65 % - is an indicator of high humidity;

- from 70 to 75 % - the humidity is high;

- 75 % and above – the humidity is very (extremely) high.

To remind, what is the relative humidity, consult the physics course at secondary school level. At first reading the definition of this value looks confusing and a little unclear. But little understood, it becomes clear that relative humidity is a quantity that is equal to the ratio of the amount of moisture (steam) in a certain volume of air (absolute humidity) to the amount of the maximum possible amount of water that can be contained in the air at that temperature. This value is measured in percent.

If the first part of the expression of special questions does not cause, the second you need to understand. Cases that water vapor can not dissolve in the air indefinitely, there comes a moment when the vapor becomes saturated and the excess moisture that enters the air, it falls in the form of condensation, rain, fog or dew. This rate depends on temperature and pressure.

The Definition of relative humidity is carried out using a variety of devices. Modern industry began to produce various psychrometers, hygrometers, hytherographs, temperature meter wet bulb, and temperature, humidity sensors, hygrometers, anemometers and other devices. But the most important thing in selling a technical device that can regulate the moisture level.

Increases the relative humidity of the air using a special humidifiers, dehumidification using air conditioners equipped with this function.
