Arriving home, many immediately rush to the windows, open transoms, ventilate the room. This is a sign that the room does not work well ventilation. It is a specialized small box with blades that let out the exhausted, polluted air stream and let freshness into the room.
Short description of the system
Despite the advantages of using a natural ventilation system in a home, the ease and ease of use, it has several disadvantages. So, the efficiency of its work does not depend on the required ventilation of the room, the performance is activated by random factors such as wind direction, etc.
In colder times, ventilation works more actively, although in the summer, performance is reduced to zero. It should be understood that the natural movement of air flows in the room is possible only with old wooden windows, although if modern europacks are installed, the natural ventilation system practically does not work.
Due to the high-quality sealing of plastic windows, mainly in the room of a bathroom, a bathroom, special exhaust air fans are installed in the kitchen.
In many situations, ventilation will be the salvation.
Ventilation system
The ventilation system can be implemented in two basic forms:
- the main valve of the window transom is installed in the upper part of the PVC windows, and thereby the air flow enters the room;
- the supply fan unit is installed in the groove on the outer wall.
The only drawback that matters, especially in our climate zone is that in the cold season, too cold air can enter the room. This will lead to illness and a cold, spoiled furniture, peeling off wallpaper and other unpleasant consequences.
In order for the installation of the air supply ventilation system to comply with SNiP, which are designed for such cases, a heater is mounted inside, heating the flows to a temperature of at least 18 degrees.
In addition, this installation includes the mandatory presence of an air filter, which can be easily removed and changed. This protects the incoming air flow from dust, dirt and soot.
The system of forced ventilation must necessarily have high-quality sound insulation.
Due to the fact that the apartments and the house do not have dimensions, most often they use monoblock inlet devices for installation. The supply unit is the most relevant, compact system, in the main monoblock of which the necessary elements are assembled.
Due to its small size, it can be mounted in apartments, on balconies, in small offices, etc. Modern advanced developments allow to carry out all commissioning operations without specialized experience and skills.
Individual ventilation systems
Individual PV, among other technical characteristics, has a capacity of not more than 100 m3\ h, which is why they can be mounted exclusively for one small room. It does not need a specialized complex network of ducts and does not take up much space. It can also be installed outside the walls, without violating the interior design.
One of the few drawbacks of an individual device is the fact that they are not intended for external use, as well as a high noise level, due to the fact that the one hundred device case is characterized by poor sound insulation.
Duct type ventilation systems
The duct ventilation system works on the same principle, but with one difference, air ducts are connected to the input and output channels. It is worth clarifying that all the supply ventilation, with the exception of individual ones, are of the channel type.
The supply ventilation system in combination with natural ventilation allows you to create a complete system. The most important thing in this matter is the need to properly place ventilation equipment, and you also need to correctly install the device and sheathe the network of channels in the ceiling space. An important factor for the proper operation of the entire system is the location of the ventilation grilles.
The system for cleaning apartments from polluted air must have a capacity of at least 300 m3\ h, for offices, the permissible minimum value is 2000 m3\ h.
How to choose a cleaner for apartments
When choosing equipment, there are several parameters that require special attention.
System performance
These parameters are selected based on the design and design information about the apartment or house, it is especially important at the same time the dimensions of the room:
- for 1-2 x room apartments, a productivity of 200-350 m3\ h;
- for 3-4 x room apartments - productivity is 350-500 m3\ h.
Static pressure
This characteristic is determined by the length of the network of air channels and their configuration features. Standard pressure is taken in the range of 400-500 Pa.
Noise level and acoustic power
In any systems, the level of acoustic noise is measured not at the input channel, but at the output from the chassis.
This indicator shows how well the ventilation system will be mounted. If the devices of the supply ventilation system provide for installation near a residential building or directly in an apartment, house. To reduce this indicator, experts advise installing silencers.
System heating power
The required indicator directly depends on the outdoor temperature, especially in the cold (winter) season. The standard accepted heating power of the ventilation system in the amount of 3-5 kW.
It should be noted that the calculated power indicator is often much higher than the theoretical load capacity of the network of air channels.
By purchasing a cleaner of lower speed, you can achieve constant maintenance of a comfortable climatic arrangement of the premises in the cold season.
To increase the air temperature at the outlet channel, possibly by reducing the fan speed. However, doing it yourself manually is quite inconvenient, so the cleaner is equipped with an automated start-up and adjustment system.
Auto setup
Supply cleaning for domestic use should include an integrated commissioning and adjustment system, equipped with a screen. The display shows the temperature of the working space, the speed of the system and many other characteristics. Automation greatly simplifies the operation of the ventilation cleaner.
Cleaning the airspace
Special coarse filters are installed on the inlet channel of the ventilation system, which protect from large particles of dust, soot, exhaust gases and fumes, as well as from animal hair and poplar fluff. To clean the room space from fine dust, you will need to install additional filters yourself.
This need is due to the location of the apartment, and the quality of the environment, as well as a number of other factors.When installing an additional thin filter, you should know that it to some extent reduces the maximum rate of ventilation system performance.
Purifier Installation Location
Considering the installation options for fresh air ventilation devices, it is necessary to correctly calculate the maintenance methods: filter replacement, major or emergency repairs, etc. To replace the filters, a service hatch is provided, which must be provided with access.
Air purification systems
When mounting the cleaner, it is necessary to consider the need for drilling mounting holes in the wall outside the building, the holes should be at least 120 mm in diameter. Simple tools that a user has in their everyday life can not cope with this question, for this you will need a professional diamond drilling machine. All work of this kind is recommended to be performed before the finishing of the premises.
Analog Home Air Purifier Options
Supply-type ventilation cleaners consume a lot of electricity, especially in the cold season. For example, if the system performance is 300 m3\ h, and the operating temperature is brought up to 18 degrees, power consumption will be approximately 4, 8 kW \ h. An apartment or apartment building often does not have such capacities and capabilities, therefore, to reduce this indicator, energy-efficient recovery units of the ventilation system are used.
The features of the installation of the purifier in apartments and country houses include the ability to install inlet devices with a water heater. The principle of operation of such devices is based on heating water circulating through a central or autonomous system.
Before choosing a specific cleaner, it is necessary to carefully study all the strengths and weaknesses of each, to understand which device is most acceptable.
