What is a microclimate
There is an intergovernmental standard GOST 30494-2011, which sets the building requirements for a microclimate of public and residential buildings. This GOST defines the microclimate of the premises as “the condition of the internal environment of a room that has an impact on a person.” The internal environment is, in the majority of cases, air inside the room. No wonder further is the clarification that the microclimate of the premises is characterized mainly by temperature, humidity and air mobility.
The microclimate, in fact, has a direct impact on man. If it is good (“optimal”, as expressed strict GOST), then a person feels a sense of comfort, and the body does not spend the power to adapt to external conditions. For example, a good microclimate eliminates heat, in which the human body would have to activate the mechanisms of thermoregulation.
The microclimate of residential and public buildings consists of many parameters, but the priority will be:
Freshness of air.
All these microclimate parameters in the premises can be not only measured, but also regulated with the help of climatic equipment. Let’s talk more about everyone.
Requirements All the same GOST for a microclimate normalizes the air temperature in the premises. In the warm period, a range of 22-25 ° C. is recommended. In the cold season is slightly lower: 20-23 ° C for living rooms, 24-26 ° C for the bathroom, 23-24 ° C for children and about 20 ° C for all others premises
By the way, in addition to the said GOST, there is also SanPiN 220.127.116.1145-10. It establishes hygienic requirements for the microclimate of premises. However, the norms of temperature and humidity in these documents completely coincide.
Regulation If the temperature is lower than comfortable, then a heater will be required. And if the batteries, on the contrary, fuel too much, then you will need a thermostat, which can significantly reduce the temperature in the room. In the summertime, you can cool down the room with air conditioning. By the way, the conditioner with the heating function will replace the heater in winter.
Requirements Recommended for a person humidity – 40-60%. Exceeding this mark is already a dampness that is fraught with damage to property and the appearance of mold. Humidity below the indicated may adversely affect your well-being: You may experience dryness in the throat, eyes. The skin can also dry up and get worse – first of all, it concerns the skin of the face and hands.
By the way, the mentioned GOST and SanPin for the microclimate of the premises indicate other figures of optimum humidity: 30-45% in winter and 30-60% in summer. However, not everyone in such indicators will feel comfortable. By the way, children need more damp air than adults.
Measurement. Humidity can be measured by a household hygrometer, a home weather station or a multifunctional NavyFlex device (which deserves a separate talk – it will be lower).
Regulation With low humidity fight with the help of a humidifier. High humidity is harder to beat, but it’s quite realistic. It will be necessary to eliminate the leakage, to insulate the freezing structures and – perhaps, the most important thing – to establish ventilation (more details can be read here).
Requirements The air in the apartment contains pollution from various sources. First, it is particles that enter the room from the outside – through open windows or a ventilation system without cleaning. It can be dust and pollen, and exhaust gases and plant emissions. Second, it evaporates from furniture, finishing materials, and objects. Often in the air of apartments you can find formaldehyde. Third, it is biological pollution from humans – so-called anthropotoxins. The human body secretes acetone, ammonia, phenols, amines, carbon dioxide CO2.
Of course, the given categories of pollutants differ in degree of danger. For example, concentrated emissions of hydrogen sulfide from a neighboring plant will cause more damage than any of the anthropotoxins. In any case, a good microclimate in the apartment implies the minimum content of pollutants in the air.
Measurement. A deep analysis of the composition and purity of air in the apartment is impossible without special equipment. Such an analysis can be carried out by a chemical laboratory. An indirect indicator of air purity is the CO2 concentration. The higher it is, the worse the ventilation. And the worse the ventilation, the more pollutants accumulate in the air of the apartment.
Regulation The air can be cleaned by means of an exhaust ventilation with a filter, for example, a compact blade. Its filters are retained as dust particles, pollen, microorganisms, gases and odors. The briser can also work as a purifier of air – to filter contaminants, the sources of which are not outside, but inside the apartment. Alternatively, you can use a brizer in conjunction with an air purifier that does not just keep infections and viruses but also destroys them, thus reducing the risk of getting sick.
Freshness of air
Requirements The freshness of air directly indicates the content of carbon dioxide, which is measured in units of ppm. As in the case of humidity, the requirements of state standards and the recommendations of physiologists regarding the optimal concentration of CO2 vary greatly. GOST “Microclimate Parameters” considers an acceptable level of 800-1 400 ppm, and doctors recommend maintaining about 800 ppm. At this point, most people feel comfortable. As the level of CO2 increases, there is a feeling of suffocation, lethargy, fatigue, reduced concentration and performance.
Measurement. The CO2 level is measured by sensors. This is, for example, in the NavyFlex base station.
Regulation The freshness of the air depends on the quality of the ventilation work. It is necessary to provide a constant inflow of fresh air from the street and a stretch of breathless air filled with carbon dioxide and contaminants. Proper ventilation solves several problems at once: it provides you with fresh air, eliminates contamination from the apartment, helps to regulate humidity.
In the paragraph above, we have already said a few words about a compact ventilation device – a brizer. So, its main function is to provide an inflow of air. Breeze brings air to 4-5 people, while purifying and heating it when necessary.
For the outflow of air is an extract in the kitchen, bathroom, bathroom. If you want to strengthen it, you should pick up the exhaust fan.
With the requirements for the microclimate, they have sorted out, with a list of climatic equipment, too. It remains only to deal with how to manage all this list.
For those who want a comfortable microclimate, and continuously monitor the indicators and manually regulate the work of the technology – does not want, there are two options.
The first is a system of “smart home”, which will include sensors and a control device for monitoring and regulation of “weather in the house.” The second one is an autonomous microclimate control system that does not require algorithms and expensive equipment of a “smart home”.
More than once the base station is part of just such an autonomous system. Moreover, the central part. It measures the main parameters of a microclimate in a house: temperature, humidity and level of СО2 (that is, freshness and to some degree the purity of air). If these parameters are uncomfortable, the user can enter the mobile application and pair of touches to set the desired indicators. The base station will manage the climatic equipment and maintain the required microclimate quality. Now the base station works with brizermi. At the end of February 2017, we presented a device for communication between the base station and the air conditioners – the IR module. Soon it will go on sale.
