Ventilation in a private house with his own hands: schemes, calculations, installation

Fresh air is needed to ensure healthy living conditions, a good quality of plant maintenance and operation of technical systems. Simultaneously it is necessary to remove the various harmful impurities. These objectives will help to solve the complex productive ventilation in a private house with his own hands. Scheme, calculations, methods of installation - all in today's review.

Construction of the ventilation system in a private home: the general parameters and requirements

Modern buildings provide with improved tightness window and door blocks. This improves the economic performance during the operation, but blocks access to fresh air. This example illustrates the need for a comprehensive approach to addressing the functionality of systems engineering.

You should also note the following for the correct formulation of requirements for good ventilation design of a private house:

• On the composition of the atmosphere in the room is able to change the state of the air in the street, the availability of sources of harmful impurities and unpleasant in the object property.
• Are essential control methods heating, conditioning, Ventilation.
• It is not excluded from entering the air pollution from household chemicals, construction and finishing materials.
• For the calculation of the ventilation device in a private home can be used technique accounting maximum allowable concentrations of impurities or indicators normal air exchange.
• We must not forget about the various needs bedroom and the kitchenIn the gym and living room.
• boilers, gas cookers and other equipment to actively consume oxygen.
• It is necessary to take into account individual physiological features and user preferences. Special attention should be exercised in the presence of allergic reactions.

It should be emphasized that the current domestic and foreign regulations, trade and sanitary standards contain inconsistent data. The above information explains the real complexity of the problem. Too many factors influence the parameters of the air in the room. In addition to objective indicators need to take into account individual preferences.

Note! For premises full exchange of multiplicity is calculated using the proportion of 30 cubic meters. m. per hour per person. Below are the correction data for different rooms and special operating conditions.

That is why, when performing the calculations for the installation of ventilation in a private house by experienced specialists make an adequate supply performance. It helps to make the necessary correction of peak loads.

Types of ventilation systems

fresh air into the room arrange the time. Changes only the intensity of the respective operations. This means that the most convenient and cost-effective is the system that performs its functions without scrutiny and electricity consumption. On the other hand, the use of forced ventilation of rooms simplifies mechanisms.

Advantages and disadvantages of natural ventilation in a private house

This simplified scheme of natural ventilation in a private house indicated the main part of the engineering structure. Here the walls are made holes through which air enters from the street. Established path for free flow movement between rooms, output channels.

To ensure the breathability of the standard (30 m above. Cu. per person per hour) is sufficient to establish the inflow and outflow pipe diameter of 150 mm or more. The height of the vertical part of doing from 300 cm and more. This typical example can be used for the calculation, taking into account the architectural features of the property.

Important notes:

• The same length of vertical tubes allow equalize drawing performance.
• Reduce the effectiveness of the system: branch, horizontal sections, the sections change.
• For ease of construction, the channels of the rooms on different floors are combined into a single ventilation shaft or mounted nearby.

In some of the input channels for retention of dust and other mechanical admixtures mounted filter elements. Such parts can significantly reduce system performance.

Note! The height of the ventilation pipe is not regulated SNIP. In practice, however, you can apply the standards for chimneys. If you perform the above rules will be minimized the obstacles to free movement of air in the right direction at a different direction and wind strength.

What is the system of forced ventilation in a private house

The air moving systems discussed above is carried out due to the different air pressure at different heights, when heated under the influence of wind gusts. The main advantage of these techniques is energy independence. However, they are extremely vulnerable to all kinds of external factors. The task is complicated by increasing the channel height.

To ensure in all circumstances the necessary performance impeller used with different types of actuators.

This figure shows the central equipment of the object. There is used a power unit which supplies and air outlet. When installing the sensors and control devices change the performance of ventilation of individual rooms. When combined with air conditioning, heating solve the problem of maintaining a comfortable temperature conditions.

What schemes are used for effective ventilation in a private house

In practice, use various combinations of natural and forced techniques. To clarify the requirements specification necessary to examine in detail the typical design solutions.

Ventilation in a private home: working principle

With this set can provide dosing of the purified air into the room:

• For protection against the ingress of insects and leaves there is a removable grille (1).
• Moving air provides an electrical fan (2). Rotor speed is regulated by the model selector (5) stepwise.
• The insert (3) of porous material retains small mechanical impurities.
• Internal grille (4) performs a decorative function.
• The sliding tube structure (6) provides a detailed view of a particular assembly with a wall thickness.

In standard definition inflow It referred to such a system which is capable of changing air temperature. Therefore, the corresponding full-type device fitted with heating elements, combined with air conditioning.

In such multi-stage apparatus set speed adjusters, fine filters, heaters. Integrated electronics allows the user modes for time, temperature operation. Simplify operation via remote control.

Modern systems combined with intelligent solutions "smart home" category for monitoring and control. This simplifies the optimization of the equipment, allows you to organize remote remote control appliances via a network the Internet.

Features of ventilation in a private house

This system is necessary for the efficient removal of waste and polluted air of the premises. With its help eliminate from the atmosphere of residential houses a gas combustion products during operation cooking and heating equipment.

In this example, we can study the solution of typical problems in a single functional unit. This system removes the damp air of the bathroom and the smell from the toilet with mechanical ventilation. The actuators are connected to the power supply separately. The toilet is installed timer. He turns off the ventilator automatically after a desired period of time after switching off the lighting in the room. Reverse air promotion blocked two valves. Contaminants are ejected through a common shaft.

This embodiment should not be increased excessively long side channels to apply a few turns. This will increase the resistance, so you will need a more powerful fan.

Note! In such systems, there are significant changes in temperature in a small area of ​​the track. This stimulates the appearance of moisture on the inner surfaces. So that condensate does not get inside the premises, you should make a slight slope toward the street for free discharge.

On a volume layout is simpler than on a flat drawing, to study the relative position of engineering systems, decorative and functional elements of the house. Such an approach minimizes the errors. In particular, for better ventilation supply and exhaust set in the room diagonally. Around the vents free space, not to create artificial barriers of air movement.

Enhanced quality of ventilation in a private house

As the name implies, this system provides a supply of fresh and exhaust air. An integrated approach allows the economical use of energy resources, consistently perform tasks.

The operating principle of this technique is clear from the figure. In the heat exchanger combine two channels (suction and delivery) without mixing. This solution helps to make the pre-heating / cooling air without using extra energy.

Below are some important facts that deserve attention:

• It is acceptable to use the same object multiple dependent and autonomous systems. In the above example shows that adjoined to the house garage better to equip a separate ventilation.
• In some rooms it is more convenient to mount individual sets of equipment. Breather can be installed in an hour. It should not be connected to the central ventilation duct. All work is done without changing the room trim.
• In assessing the level of channel noise units experienced specialists recommend making measurements in the area of ​​the inlet and outlet openings, about units equipped with electric drives. Manufacturers indicate the acoustic power and sound pressure in the accompanying documentation. For comparison, we must take the same parameters.
• Full-power heating elements exceeds 3 kW. This allows you to quickly raise the temperature at any time of the year. But we must make sure that the wiring and other network components are designed for the respective load. If necessary - adjusted liquid heat exchanger.
• Automation parameters should be checked carefully. Make sure to use the remote control convenience, ease of configuration. Also typical speed change fan useful ability to set individual time schedule. At night, for example, lower the temperature, the intensity of ventilation.
• Useful to save user settings in memory. Maintenance is simplified if there is a differential type pressure sensor. This instrument measures the pressure change before and after the filter. Increasing the difference in readings will report excessive pollution. The cheap versions set alarms "on time", that do not provide high accuracy control.
• Self-diagnosis by means of software and electronic media help to know in good time about the problems of equipment. Additional features provide the user with an alert message forwarding on your smartphone, or other mobile device, a desktop computer.
• As standard equipment household purposes set G4 filters, which are capable of fluff poplar, bird feathers, and other larger impurities. If necessary, instead, or sequentially set elements with small channels. Acceptable detainment particle size less than one micrometer. We must remember that this modernization will increase the load on the air handling units.

In the development of design documentation necessary to separately examine the question of the future operation. Ventilation equipment will have to serve. It is necessary to avoid situations when the inspection and performing routine maintenance necessary to dismantle part of the decorative finish, building structures. For this reason, it is more convenient to place the fans, filters and other components of the system in a special technological area. This solution will simplify the creation of an effective isolation of noise ventilation unit.

What should be considered when equipping the individual rooms

In the course of flow distribution is necessary to provide the initial penetration of air from outside into the living room, bedroom and other living room. From there - it is sent to the technical premises, on the kitchenIn closet, restroom, bathroom. This decision will create a positive pressure in the places of permanent residence, which prevents ingress to odors and other contaminants.

Note! According to current regulations bathrooms with "constant presence" are spaces in which people are more than 6 hours for one day, or 2 hours continuously.

The following guidelines will help you choose the right equipment for different parts of the property.

Ventilation in the kitchen in a private home: the rational solutions to complex problems

In this room in a wide range temperature changes, humidity level. The process of cooking is accompanied by the appearance of odors, air pollution hazardous to health and persistent impurities. It should take into account not only the intensity but also a greater incidence of a variety of negative effects.

Also need to be aware of the features of the kitchen appliances. If you have installed electric hob, Should ensure that the exchange of air not less than 60 m. Cu. per person per hour. When mounting this standard gas plates is increased by 50% (up to 90 m. Cu.).

Note! The minimum distance from the hood body to a gas / electric oven must be at least 65/75 cm, respectively.

The principles of coordinated work between the two systems:

• Fig. "BUT". Initially, the construction of the house is provided only natural ventilation with openings (2). It can be seen that part of the exhaust duct (1) after mounting will reduce the common channel section (3).
• Fig. "B" shows the work check valve (5), which is set for decorative grille (4). When drawing the fan is turned on it is closed, overlaps the air movement in the opposite direction.
• The following figure "C" shows the work of natural ventilation.

Desktop drawing down inside of furniture when turned off. It can be connected to the ventilation shafts on the template, top. But the proper channels if necessary to create a floor screed. The latter variant is associated with significant changes in the architectural designs. It is used in the construction of the house, in the course of renovation.

hoods for kitchens

To maintain high performance in the design of the connection hood must take into account the following details:

• work is not difficult with the corrugated pipe. However, these products provide a greater resistance to air flow compared to the smooth channel walls.
• Duct-section is selected in accordance with the manufacturer's instructions. It should not get less than the specified value.
• When laying track is necessary to prevent collapsing of flexible pipes, and other significant deformations. Minimize the number of turns.

Approximate calculation of the required extraction performance can be made according to the formula P = (L x W x H) x 12 x 1.25where

• P - the maximum amount of air removed from the room per hour in cubic meters;.
• D, W and AT - length, width and height of the room in meters;
• 12 - standard correction factor;
• 1,25 - additional headroom, which is useful for the rapid removal of fumes from the burnt food.

This operation can be performed safely with steam over boiling water. Special detergents are also used. For a reminder of the regulatory procedures hoods equipped with electronic timers with audible and visual alarms.

Here hood complemented by air conditioning. This technique is more expensive than standard models. But it is able to maintain the room temperature set by the user mode.

This equipment acts as a filter. With the help of delayed pollution. As a general rule, apply the additional elements with carbon fillers. These sorption technology helps remove the smallest impurities and odors. But in any case it is necessary to provide job ventilation system. In the present embodiment uses the existing shaft. To improve performance, set enforcement mechanisms in the inlet (outlet) tract.

How to create good ventilation in the toilet and bathroom

For the calculation of the needs of those parts of the property use the following air exchange regulations in m. Cu. in an hour:

• 25 - for every single room;
• 50 - combined bathroom.

Lack of efficiency of ventilation in the bathroom in a private house contributes to the appearance of mold, fungal colonies. Also an unsightly appearance deteriorates atmospheric composition. Some microorganisms provoke dangerous for health diseases, so that preventative measures can be called a binding. Of course, we must not forget about peeling paint and damaged other decorative coatings, the intensification of the destructive processes of corrosion.

The air here can be fed from the living rooms, corridors. If not enough available slots in the door leaves do through holes with plastic inserts.

the supply valve on the window

Features natural ventilation for such spaces is not enough. Therefore use more efficient enforcement system. Selection of fan do to suit individual circumstances. The above are the minimum regulatory requirements. They are not enough, if you often take a shower, when a lot of people living in the home. As in the case of the kitchen, there is better to install an adequate supply of power.

Note! instead of "12" for an exemplary calculation of the above formula can be used to "5" coefficient.

Reinforcing wall a scrap plastic pipe. The mounting location is chosen at a distance from the plumbing fixtures in order to prevent accidental splashes on body art.

When choosing a technology is necessary to pay attention to the features of modern models:

• The grille and the body of solid polymers are not damaged under conditions of high humidity, temperature changes.
• Wind vane with a large number of blades creates a strong flow of air at relatively low speeds, with minimal noise.
• The vibrations from the electric actuator to effectively quenched with damping inserts.
• rotor support on ball bearings are designed for continuous heavy-duty use.
• Good sealing of joints of individual parts prevents ingress of moisture.
• Low weight simplifies installation.
• Some models, or out of the box, fitted with non-return valves.

Note! When choosing a small room fan pay attention to the noise level. The value of 35 dB or below can be called entirely acceptable. If the manufacturer have less than 25 dB, the sound of the electric drive will not be heard at a distance of several meters.

After all, in the garage it is not only necessary venting, but also to maintain the humidity at the required level - its excess reduces the lifetime of the car.

The above examples are suitable for the organization in the lower part of the building suitable conditions for storage of vegetables, conservation, gardening equipment, consumables.

In this case, for calculation of the system and the individual parts used standard rules for living rooms. Make an additional margin for the sports hall, shower room, kitchen block. Performance increase via forced ventilation.

Important! To find out how to make the ventilation in the basement of a private home, it is necessary beforehand to create a list of requirements, taking into account the characteristics of individual facilities. It is also important mode of operation.

Mandatory requirements for the boiler room ventilation

ventilation system parameters when installing gas appliances are well established existing building codes and regulations:

• Minimum inflow performance is determined by the boiler characteristics. Normalized input channel cross-sectional area (cm. sq. 1 kW of heating equipment):

1. 8 and, if the inflow is made directly from the street;
2. more than 30, when the air flows from adjacent spaces.

• The outlet on the ceiling do. It is connected to the central ventilation shaft at home.
• Besides the main chimney necessary to set the second channel (below 25-30 cm) for routine inspection and contaminant removal.
• The volume of the room do not less than 7.5 m. Cu. with a total capacity of heating equipment up to 30 kW.

Suitable for ventilation gas boilers in a private home must provide at least three complete cycles of air exchange per hour.

Important! Calculation of the boiler room ventilation must exactly match the current regulations SNIP. If the home make it too complicated - check with the experts for help. Keep in mind that non-compliance is punishable by substantial fines. Alterations incorrect project will cost more than the cost of training of the design documentation.

Features of attic ventilation

To maintain the high temperature here year-round will require too much energy. Instead, use high-quality warming ventilation ducts.

These elements are mounted on the same distance from the eave side faces, the ridge. The distance between them made more than 1.5 meters. Should give sufficient attention to aesthetic qualities windowThat they do not violate the harmony of appearance. The overall dimensions of such openings shall not be less than 1/500 with respect to the total area attic.

Note! This heated loft in a private house ventilated by conventional standards for premises.

How to perform its functions ventilation sewage system in a private home

In sewage ventilation scheme in a private home it can be seen that the number of output channels is determined by the design of the sewer system. Here one pipe installed before septic tank. The second - on the far side Infiltrator.

• chimney (1) connected to the heating equipment;
• "Backlash-channel" (2);
• wood (3) iron and (4) a cover;
• the output portion of the ventilation system (5);
• brickwork (6);
• clay locking (7), which prevents the penetration of dirt into the soil.

Ventilation cap: important nuances

If this part of the building is not in use because of the low altitude, or for other reasons, appropriate protective measures. good ventilation Organization foundation in a private home without a basement prevents damage to the wooden parts of the construction process of putrefaction, the emergence of dangerous to human fungal spores.

Note! Installation of the ventilation of a private house basement is necessary for the timely removal of radon. This radioactive gas was not determined by the senses of human.

Normalization moisture level in the pool via productive ventilation

This information will help formulate the right requirements for the airing of the relevant premises:

• Experts recommend not to increase the water content in the atmosphere over the level of 14 g per kg of air.
• Normal relative humidity range from 40 to 655.
• If the surface temperature is lower than the dew point, condensation occurs intensively. Such processes in particular, can be observed on the outer walls of the pipe duct.
• In order to prevent drafts and respiratory disease caused by them, the velocity of air flow should not exceed 0.15 meters per second.
• Increased pressure in the room (a special adjustment of supply and exhaust) will prevent the ingress of chlorine chemicals in the other rooms. If this backwater establish a 15-25 Pa can be obstacles when the doors are opened.

How to make the ventilation in a private home: the preparation of calculations, project documentation

During the calculation of ventilation in a private house professionals determine the following important parameters:
