Forced ventilation. Forms and installation of mechanical systems for ventilation

mechanical ventilation systems provide effective ventilation and can be cleaned, heated or cooled air coming from the preview

Forced ventilation. Forms systems with mechanical drive

While, when the temperature in the flat is aligned with the outdoor temperature, the natural draft ventilation becomes weak or disappears altogether. Through the use of special devices provided by artificial ventilation. To learn how to make a forced ventilation, it is important to investigate the types and purpose for different premises.

Forced ventilation may be classified according to their purpose and depending on the configuration of execution. Distinguish the following types of mechanical systems:

• forced ventilation - such a system provides forced inflow of outside air;
• exhaust ventilation - at which air removed from the room by mechanical means;
• supply and exhaust system - when both the inflow and the air output is artificially.

The system of compulsory ventilation It provides an effective air exchange even in enclosed spaces

In turn, depending on the specific area, which is served by one or other coercive system, it can be local or the general exchange. Local forced ventilation is characterized by the fact that the supplies or draws air in a specific area of ​​the room, while the general exchange produces airflow throughout the room.

Considering whether the forced ventilation duct system, they are divided into ductless (air fed through the wall or window openings) and channel (air circulates through vent). By way of mechanical ventilation devices can be composing (separate devices connected duct) and monoblock (all units are assembled into a single compact housing).

forced ventilation apparatus

Build a system of forced ventilation of private homes or apartments with their own hands, you can use the connection of the various elements into a single system, including:

• grill for air intake - is mounted on the outer wall of the duct exit, ventilation protects against ingress of small objects and animals;
• filter with varying degrees of treatment - used for air purification;
• The air valve - controls the flow of air into and blocked off from the outside when the vent mode;
• heater - heats the incoming air in the cold. For apartments usually use electric heaters. In private houses more than a hundred squares - water heaters;

The automatic ventilation system air heating and air-conditioning

• silencer - serves to absorb noise in the operation of facilities;
• fan - provides the required air pressure in the system;
• duct - distributes the air movement in the room;
• diffusers - blow air into the rooms of an apartment or house;
• automatic control system - management and control of the ventilation system.

At the device of a forced ventilation system in the apartment with his hands, it is necessary to determine the place of installation. The equipment should be located as far as possible from the living room, bedrooms and children's rooms. Acceptable place ventilation installation is the kitchen, hallway or balcony. If the system has a high-quality sound insulation, noise from the work can not be heard through two closed doors. As for private homes, the system can be installed in a utility room or attic.

forced ventilation equipment is best placed in the attic or in the basement, to isolate the source of the noise

Plants and equipment for systems with forced air exchange

On what functions will have a forced ventilation, which you plan to equip the house with his own hands, it depends on the choice of the necessary settings for it:

• System of compulsory ventilation, producing heat incoming air, called recuperative ventilation systems. To install such a system with your own hands, you need a device - recuperator. With this device you can achieve air quality, as well as heating and air conditioning;
• installing recirculation - allows heated or cooled air masses, thus saving power consumption. This is due to the fact that the room is supplied outside air is mixed with warm exiting the premises to be heated and only air from outside;

Putting it all together ventilation systems must be very dense, so as not to split under the pressure of the air

• installing cooling air flow - is used in the summer at high temperature for cooling (mainly used for building, in which are stored perishable products);
• air conditioning system - includes air conditioning, Cooling apparatus and automatic control of air temperature. Is relatively expensive equipment.

One of the simple ventilation device which can be mounted with their hands in the apartment or private home, a supply valve. Such an installation is supplying fresh air flow from the street, through a filter producing its processing. Control the air flow volume by using the damper. The air supply valve is equipped with a silencer. This is a fairly simple device provides ventilation in a private home or apartment, where fitted windows of metal.

Installation of the mechanical ventilation system with their own hands

Following the recommendations can be made compulsory ventilation by hand. First, the supply valve is mounted.

For the installation of the wall of the supply valve is necessary:

• make a hole in the wall through about 7 cm in diameter. The pipe insert hole;
• outside pipe cover grille, thus providing protection from getting into the pipe of small articles and street litter;
• the gaps between the pipe and the hole for mounting blown foam. In the pipe duct mounted inside a room provided with noise insulation.

Wall air inlet - a simple solution forced the supply of fresh air into the room

Useful advice!To a cold season the air entering through the ventilation valve was warm, the valve must be positioned over a central heating radiator.

Apparatus mechanical exhaust system in a house or apartment at the expense of the fan installation. This ventilation system is suitable for bathrooms, toilets and kitchens. It is recommended to choose the fan with the most silent operation. Such a device is a centrifugal fan.

Equipment for drilling of through-holes for the improvement of the supply valve

Useful advice! In the event that either repair the ventilation system, after holding it to check the quality of the tightness of all connections.

Installation of mechanical ventilation in the kitchen

Arranging ventilation in the kitchen, many believe that will be enough cooker hoods. But such a forced exhaust system is unable to remove all of the exhaust air. In addition, there remains a need in the fresh intake air in the kitchen.

extract Stove ensure removal of used air, steam and odors, but can not provide the quality exchange of air in the kitchen

In order to provide quality ventilation in the kitchen is primarily determined by the place of supply and exhaust openings located. Holes punched in the kitchen is recommended to the wall where the window is located as close as possible to the ceiling. Next, step by step following the instructions, perform the following steps with your hands:

• mm diameter holes 120 for ventilation hoods and the kitchen are arranged next to each other as possible;
• a pipe inserted into the knockout holes (ducts) slant towards the outside, to remove the condensate. Remaining between the pipe and the hole closed up the gaps with foam. The pipes must protrude from the wall by about 5-6 cm;
• as soon as the foam dries on the pipe, which is located closer to the wall of the kitchen, which is planned placement of furniture, It sets a check valve (to insert the apparatus correctly follow so that the arrow indicates the direction outwardly);

Choosing a trusted manufacturers forced air systems, you can count on a long life and quality service for installation and maintenance

Please note that the air ducts must necessarily be attached to the existing ceiling of not less than one meter. For the system while working less make noise, it is recommended to use rubber pads under the mounting brackets. You can use sound insulation materials, such as mineral wool.

Arranging a forced ventilation in the kitchen, you need to choose the power of the exhaust equipment, since it affects the output rate of the exhaust air.

Useful advice!If you are going to replace the filter of the cooker hood or clean equipment, follow the manufacturer's recommendations and be sure to unplug the appliance.

According to the norms, pick-drawing equipment in the kitchen with a reserve. You can adjust the output speed with a few built-in speed mode.

forced ventilation device with his hands in the toilet

Bathroom with WCTaking into account the resulting humidity there, especially in need of high-quality ventilation. If natural ventilation in the apartment weak, during the operation in the bathroom and the toilet is formed fungus, mold appears and persistent bad breath. The situation will correct organization of forced ventilation in the toilet. Before you start to equip forced ventilation in the bathroom and toilet, should be checked and cleaned, if necessary, the ventilation duct. This is especially true of toilets and bathrooms of the apartments, which are located in old buildings houses where often there is a blockage and destruction of ventilation shafts. This can be done by hand or contact the experts of housing and operational management.

Forced ventilation in the bathrooms provide fresh air and dry premises

in the toilet using a fan for forced ventilation. A suitable device is a fan with a humidity sensor and a timer, which will be activated independently with increasing humidity and off after a certain period of time.

The fan is mounted in the suction channel opening in the the toilet and fastened to the wall using screws or dowels. To the device connected all the wires, which are then carefully hidden. Wires can be hidden under plastic boxes. Given that the toilet, bathroom with bath, quite humid, the wires are connected to the terminals.

Forced ventilation with automatic control allows you to create in the room most comfortable conditions

Forced ventilation in the bathroom and toilet allow air to be cleaned in a timely manner and does not give an unpleasant smell spreading throughout the house.

Leveler forced air in your home or apartment to help cope with long-term problems lack of ventilation, especially in rooms with high humidity, will relieve you of fungus and will help preserve health.
