Ventilation of a country house and cottage, projects, how to choose the best option, installation features

For a comfortable stay in the cottage it is important to ensure good air circulation. The ventilation of the cottage has a special scheme and must be developed by qualified specialists. Owners of future housing can offer several options for the air circulation system - natural, combined and compulsory. It is important to remember that the design of the cottage and the ventilation system is interconnected, so the process takes place simultaneously.

Types of cottage ventilation

Natural type of ventilation saves electricity, but has some cons. To ensure proper air exchange, it is necessary to prepare an outflow system in the form of ventilation ducts. The level of thrust is achieved only by the appropriate length of these channels, so the option is suitable for two-story buildings and more.

For single-storey houses it is recommended to choose a combined type of ventilation. In this case, fans are mounted at the mine entrance - the air flow remains natural, and the exhaust hood is operated with the help of fans. For a uniform flow and outflow of air masses, it is important to choose the right fan power relative to the floor space.

Forced ventilation is used if the previous options are ineffective. For the arrangement of the duct network system, filters, fans, valves, coolers and heaters are used. The system can work automatically according to predefined parameters.

Purpose of ventilation

Modern cottages are built of heat-shielding materials that provide high tightness, but preventing natural air circulation. The problem can be solved by high-quality ventilation, which provides the following indicators:

• creating comfortable living conditions;

• fresh air is supplied to all rooms;

• evaporates and exhaust air are displayed;

• interior items and housing are stored;

• there is no stagnation of air, moisture does not accumulate;

• the mold or fungus does not appear;

• the air is cleared of contaminants.

There are constructive differences between the ventilation of the cottage and any apartment, so the organization is different. The differences are in a simplified filtering system, autonomous work equipment can be mounted in the cottage, it is enough to correctly place all the elements and relationships with communications. For specialized rooms requires a special mode of ventilation.

The special nuances of the system design must be taken into account:

• frequency of use;

• climatic features of the area;

• designation of all rooms;

• total area of ​​construction.

These are important points that must be taken into account in order to create high-quality and high-performance ventilation of the building.

Basics of natural and forced ventilation

Natural ventilation of a country house is the easiest option. It is based on the natural conditions and the use of the difference in temperature and pressure inside. There is a natural thrust that circulates air, removing waste streams from the building, into the place that come clean. For air intake, special valves are installed in the form of openings with closed grilles. They do not create drafts, but provide the necessary air flow. Such valves may close when it is very cold outside. Additionally, they can be equipped with filters, humidity sensors and noise suppressors, and can operate in automatic mode.

The waste mass is removed by a system of pipes, the outlets are located in the most polluted areas. The air is drawn out by means of a thrust, for which the exit of the pipe is placed at a height of at least 0.7 m above the roof, the hole is covered by an “umbrella” that protects the system from ingress of sediment, garbage, small animals and birds.

Such a system has its advantages:

• low cost;

• quiet operation;

• no cost during operation;

• easy installation.

The disadvantages of the system are dependence on weather conditions, heat loss during the cold season, lack of control of outgoing and incoming masses, inefficiency when there is a pool or sauna in the cottage.

See some more reflections on natural ventilation in the video:

Inefficient or improper ventilation uses a forced type that uses high-tech equipment:

• filters, fans, valves;

• air coolers and heaters;

• ductwork.

At the same time, the system delivers clean air to the house at a comfortable temperature and removes the waste air. Parameters can be set in advance, which allows the system to work automatically. Installation of the system is carried out with the installation of the ventilation unit indoors. The ducts are laid with all components installed, the system is prepared for operation. Installation of equipment in each case is considered individually, the placement of the unit, components and duct is agreed with the customer. The most economical and technologically advanced option is a supply and exhaust ventilation system with a recuperator. A special recuperator takes heat from the heated air, and then heats fresh air coming from the street.

This is an effective method of ventilation of rooms, the system does not depend on various natural factors. But the system itself is quite complicated, so the appropriate specialists must develop. It is important to develop a competent layout of all highways, diameter and length, pick up all the elements. Periodic maintenance is required, but it allows to provide favorable and comfortable living conditions with full guarantee.

Design of ventilation

Any project of future ventilation is carried out with the obligatory account of the norms of air exchange for each individual room and in general for the whole building. In accordance with the norms and requirements, the air exchange should comply with the following indicators:

• room 3 m ³ / h for every 1 m ² residential premises;

• bathroom, washroom, shower room 25 m ³ / h;

• combined room 50 m ³ / h, 25.

The parameters are given for the temperature in the colder season, inside the room the temperature is 16-25 ° C.

For the basics of designing ventilation, see the video:

The project of a cottage ventilation is developed by specialists at the building design stage. For this purpose, the terms of reference are compiled, it takes into account the following points:

• building architecture;

• number and function of rooms;

• floor space;

• additional objects that affect air movement;

• the number of permanent residents.

In the calculations, the system capacity for each room separately and the entire building as a whole is determined. This parameter depends on the frequency of air exchange of rooms and the maximum number of people in one room.

After creating a project, ventilation can be installed, over which only specialists should work. The process itself takes place in several stages - the preparation of the scheme and the project of the house. In this case, all other communications and systems are taken into account. Installation and design of ventilation in country houses is quite a complicated procedure and errors should not be allowed here. Otherwise, they will not be able to meet their goals. For example, the ventilation system requires preparatory actions:

• determination of power grids, their tab and possible reduction of energy consumption;

• the possibility of installing special equipment, and also arrangement of air ducts;

• selection of equipment taking into account the characteristics of the premises and operating conditions;

• installation of all the selected equipment.

Conclusion

Professional ventilation will make your stay in the cottage safe and comfortable. The system will operate continuously for the benefit of man.

When using modern equipment, you can control the flow of fresh air or set the system to operate in automatic mode.

Such systems allow you to make your stay as comfortable as possible at any time of the year and in a variety of weather conditions.In addition, a high-quality room ventilation system allows cleaning the air from pathogenic microbes and microorganisms. This is a very important indicator, especially if there is a small child in the house. The correct calculation of ventilation is a rather complicated task, the solution of which should be handled by professionals.
