properly designed ventilation system in the living roomnot only contributes to a comfortable stay in the rooms, but also reduces the likelihood of diseases of the residents themselves.After all, in the old stagnant air, especially in close little room, crowd huge numbers of harmful bacteria that can become not only pathogens of fungal structures on the walls and ceiling.But can cause serious diseases to humans.Therefore, consider the question of design and installation of the ventilation system must be taken seriously and responsibly.

Types ventilation

type and the type of ventilation system depends on the purpose of the premises, which can be bath, kitchen, living room and so on. With high-qualit

y construction is necessary to design the ventilation center and in all rooms, but modern apartment building limitedventilation of toilets, bathrooms and kitchens.In multi-storey buildings, as a rule, there is a central well, in which all ducts converge.In recent years, most individual wells are designed for kitchens and bathrooms, which are joined at the technical level.

What is needed for installation?

Ventilation in apartment buildings is the installation of dampers, valves, air valves, fans, grilles, because the channels are already available.But sometimes you want to expand it, or to move a couple of centimeters, and then require the proper tools to work with concrete.For the installation of complete systems will need the following tools:

  • sealant;
  • set of screwdrivers;
  • punch or drill;
  • elements for ventilation systems;
  • dowels and other hardware.

Why ventilation in the bathroom?

As previously mentioned ventilation is a comprehensive tool for protection and comfort.It has the following positive qualities:

  • Provides the most favorable indoor climate.This is achieved through the use of active systems using controlled motors or controlled damper.This quality is composed of two parts: the temperature and humidity.Only by maintaining these two parameters in the desired range can achieve the maximum comfort and quality of life.
  • ventilation system is an excellent tool for integrated airing the room if necessary.

WC, especially combined, and is just a place where very often there is high humidity and odors at the same time.And at the same time in these rooms do not have windows, for obvious reasons.To get rid of negative factors necessary quality and high-speed ventilation system, in addition to the natural, called forced with automatic or manual control.Another reason for the use of forced ventilation is the weather factor, which is constantly changing, the strong wind and the rain or generally windless and warm hot summer sun.

properly designed and the installed system will ensure prompt removal of all odors and steam from the premises before the exit.Thereby maintaining the same climate and atmosphere in the other rooms of the apartment.The constant high humidity promotes the generation of condensate which is deposited not only on glasses and mirrors, but also on all other surfaces, both horizontal and vertical.That, in turn, even after a short period of time will lead to infection by the fungus walls, mold on the ceiling and in the corners, and the corrosion of metal objects and furniture in the plumbing.And it is fraught with subsequent costs of holding the next repair.Therefore, it may be noted one more positive quality of ventilation systems in rooms with high humidity - is economic.ventilation in the apartment , and the correct operation of distribution flows

reasons ventilation system malfunction

How to check ventilation in the bathroom? If you feel that in the room there is an air blockage, it became difficult to breathe, that is, the probability of a natural ventilation system malfunction.It is necessary to check its functioning visual way, to do this you need a source of heat and patience.It is necessary to open the vent to bear the fire and observe its behavior.With proper ventilation of the flame is tilted at an angle of 450. If this is not observed, the natural system is locked.As a result, there is a smell in the bathroom of ventilation.This is more likely the case is due to the clogging of the channel with foreign objects, at least - hit her birds.To ascertain and eliminate the cause of the obstruction must be treated in the utilities that free compulsory conduct the necessary technical work.

After checking the natural, you are ready for installation of forced ventilation system.

Forced ventilation system for the bathroom

For the design of ventilation systems are used any normalized data, which depend on the size and functionality of the room.According to the tabular data exchange of air in the bathroom should be made with a capacity of at least 25 m3 per hour, in the case of a combined unit, the figure should be at least 50 m3.Performance depends on the dimensions and design of the building ventilation shafts.

Before installation of the ventilation system, should understand the concepts of:

Natural ventilation - is the exchange of air masses from the open doors and windows to the channel (it should be taken into account when checking the suction capacity);

artificial or forced - air circulation system uses active (fans, dampers).

in turn can be forced as several types:

Ventilation - for the exchange of air masses air taken from outside through the ventilation ducts;

Exhaust - air is transported out of the room channel (standard system in apartment buildings);

Mixed - combined use of both directions of movement.

In modern construction in multi-storey buildings designed ventilation joint between the bathroom and toilet, t. E. There is no direct access to the vent and in the adjacent wall with a toilet is a hole.Through him, and there is air circulation, and in the case of the bathroom - the movement of the pair.In connection with these two systems can be distinguished:

Channel - Additional air ducts are used, connecting bathroom with the central channel;

Underground - steam output going to the bathroom, and from there into the channel.

engine type selection for ventilation

Do I need ventilation in the bathroom?The need to install an additional system arises with reduced previously illuminated indicators or, if necessary, the operational climate control.In any case, the improvement of an additional installation of the ventilation system in the bathroom only improves the quality of life.

forced ventilation system in the bathroom is only a few components and professional electrician.But before any work you need to choose the right fan.It should have a high index of electrical safety.This is due to the fact that it is always in the bathroom humidity, as water is an excellent conductor of electricity.

Also, there are several fan installation types:

radial - mounted directly in front of the channel;

channel - installed in the channel itself.

By design features fans are divided into the following types:

Centrifugal - provides maximum flow, but create the most noise;

Diametrically - mene noisy, but less productive because of the working body of the drum structure;

Axial - is widely used in channel-free systems, because the air is captured by the blades, and flows along the axis;

Universal - a combination of centrifugal and axial, which made it possible to obtain smaller dimensions, high performance and low noise figure.

Proper ventilation in the bathroom should begin with preliminary calculations.They are based on determining the volume of the room and the fan performance.For example, to place a volume of 9 m3 require a fan with a capacity of 72 m3 with a family of 4 people.Further, the motor nameplate data selected in the range from 72 to 100 m3 per hour.

Choosing the type of control ventilation

Ventilation in the bathroom can be equipped with various fan control systems:

Manual - set a separate switch on the engine;

Synchronized - motor circuit is connected to a light switch;

Automatic time and simultaneously synchronized - fan power supply circuit connected to the light switch, but switches off automatically by timer;

automatic - controlled by humidity sensors.
