Surely you have repeatedly come across the problem of false windows, wet air and damp on the walls. These troubles are associated with insufficient ventilability. Help you solve these problems can install ventilation. It remains only to choose the one that will suit you.

Types of ventilation, choose the desired

1. Natural.

Natural ventilation is based on air temperature difference in the room and the exhaust pipe. Warm air located in the pipe is lighter than cold, so rises up the pipe and goes out. Thus, circulation is carried out. This is the easiest way of ventilation, but not reliable. The quality of his "work" directly depends on the air temperature on the street and weather conditions, for example, from the presence of wind. You require the accurate calculation of the installation of the ventilation system and protect it from corrosion and damage. It can be installed with your own hands, only time and materials are required.

2. Supply.

Supply ventilation is most appropriate for country houses. Such a system saturates the room with fresh air and removes wet. It is effective, but the system takes a lot of space due to the fact that the "double" design of the air input / output is required. On the windows, doors or walls are installed inlet valves for entering air from the street to the house. The exhaust system removes the air from the room to the "sucking" street with the help of exhaust fans. Installation is made only by specialists with pre-careful calculations and measurements.

3. Automatic (energy efficient).

For automatic (energy efficient) ventilation, an air conditioner is required with an air duct, a calorifer and filter. For confidence that clean air falls into the house, do not forget to clean the air conditioner filters. Modern elements of the energy efficient ventilation system are installed on plastic or wooden windows (on the sash). Automation itself adjusts the flow and outflow of the air. Installed by specialists, does not tolerate non-professional interventions. Even a minor defect when installing threatens with an impaired air exchange.

Ventilation system selection parameters for cottage

1. Performance. Having calculated this parameter, you must take into account the area of \u200b\u200bthe premises, the number of people living in the house, the number of household appliances. Count how much time and how the volume of air will be required to withdraw the contaminated air and filling clean. The optimal value of the air exchange in the cottages is 1000-2000 KB. m / h. To calculate, we multiply the height of the room area and 2.

2. Permissible level of noise. The greater the speed of ventilation, the higher the noise level. Do not buy too "fast" systems. Calculate the first right point and thereby save your budget and calm sleep. It is not worth gaining air ducts with low indicators. In this case, they may not withstand the load during operation and it is hard to install it. The average air flow rate is acceptable to the cottage - from 13 to 15 m / s.

3. Power. The calorifer should regulate the temperature of the incoming air to the room. According to standards, the temperature should exceed the indicator + 16 degrees. Calf power is calculated depending on the place where the device will be installed. It should be able to work in winter when the street is minus temperature. When choosing power, focus on the maximum positive and maximum minus temperature indicator. If the maximum minus temperature on the street is -10, the calorifer must heat the air at least 26 degrees. For example, 1-5 kW power is enough for the apartment, and up to 50 kW can be used for office space.

Cottage ventilation scheme

• Air processing unit.
• Automation unit.
• Street air fence device.
• Devices for delivery and redistribution of air inside the building.
• Devices for removing air from the residential area there.

Equipment installed in the ventilation system is sufficiently powerful. Some can consume more than 50% of the energy, which is allocated to all engineering systems (heating, water supply, etc.). Energy-saving equipment is used to solve this problem, for example, the heat exchanger. The use of this class devices allows the reduction of energy consumption to 50%.

The design of the heat exchanger consists of a plate heat exchanger, air supply and removal fans, air purification filters and a heater. The heater is turned on in the winter season for heating air coming from the street. The operation of the supply ventilation of the cottage, its control is carried out by the control system.

The main task of this system is to maintain the temperature of the incoming air in accordance with the requirements of the homeowner. To achieve the task, the temperature sensors are used street and internal. If necessary, the / disconnection of heating elements occurs.

The ventilation system is a complex engineering and technical system that uses various devices for its work: drives, heaters, etc. A failure of one element can lead to a failure of all ventilation in general. To prevent such situations, engineers are laid in the cottage ventilation project equipment protection against voltage jumps, overheating elements.

An indispensable part of the protection system is the fire system. It is it that tracks the temperature modes inside it, both on the equipment and in the air, moved in pipelines and, in the case of the system output to abnormal modes, it makes it disconnected to determine the reasons.

Auxiliary equipment

To ensure the full operation of the ventilation system, a set of auxiliary equipment is included in the cottage ventilation project. It provides a fence of atmospheric air and air output from the premises.

To save heat in the house in the winter, when the ventilation system does not work, these devices must be equipped with insulated valves equipped with both mechanical and manual drives, to ensure complete reliability, it is advisable to apply the valve heating system to ensure complete reliability.

Air ducts for which air moves must be provided with both thermal and sound insulation. To transport air inside the building, use both pipes of rectangular and round sections is allowed. Sizes of sections determine the designers when calculating the ventilation of the cottage.

As a material on ducts, both metal and polymeric materials are used. In order to suppress noise, the movement of the air and the operation of the mechanisms, acoustic silencers of various shapes are used.

Stages of installation of ventilation do it yourself

The project is determined by the attachment points of the equipment both the main and auxiliary, restrictions are imposed on its placement, for example, it is not recommended to install equipment over temperature sources - fireplaces, furnaces, etc. Designing of the cottage ventilation requires knowledge of the set of many requirements for regulatory and technical documentation. .

1. Preparation.

• on the wall we make markup at the installation site of the ventilation;
• issue it, taking into account the reserve in a couple of centimeters. The stock is needed for a comfortable installation of the system;
• i obey the edge of the opening so to make them smooth.

2. Mounting.

• install the front of the fan in the cut pipe;
• we place the design in the hole;
• pour the space between the wall and foam fan.

3. Packing electrics.

• stroke wall;
• in the hole we pave the wire to the fan;
• fix the wire brackets.

4. Finish.

• install the protective box on the fan switch;
• all junctions of the ventilation system are wicked by sealant;
• we shuffle and put the place of the system adjoining the system to the wall and furrows with wiring.
