If you are planning to arrange a private house in the hood, we will share with you all the details of the case. This publication will be considered particularly natural and forced ventilation, as well as methods for their installation. To make it more clear, we have added material photos and videos.

natural ventilation
Natural ventilation is carried out by the difference of density and temperature inside and outside buildings. On the traction affect:
- channel section;
- wind direction and strength;
- the presence of turns;
- insulation system.
This kind of ventilation is based on the channels that are in an upright position. In great demand due to the availability of the financial plan and simplified design. The system eliminates the presence of complicated elements and mechanisms, and this is due to its reliability. As for her service, everything is quite simple, just enough time to time to carry out its inspection. Fresh outside air is heated actively. Pour into a ventilation system is not regulated, which negatively affects the microclimate. It is running in silent mode.
There have natural extracts a number of significant shortcomings. First and foremost it is worth noting its dependence on weather conditions. In the summer, on hot days, when the outside air temperature is higher than outside, the ventilation is not the strength to perform its functions. In the winter time there are significant heat loss. Moreover, the room opens the ingress of dust and insects.
Choosing the diameter of the channels for ventilation, need to focus on the size of air. If ventilation is installed in the toilet, it is considered optimal rate of 30 m³ / h, for the bathroom a little more than 50 cubic meters at one o'clock.
forced ventilation
Supply and exhaust forced ventilation system comprises a heat exchanger, fans and filters. Clean air, which is supplied from outside, is warmed and circulated through the chambers. If it is contaminated, it is forcibly pumped out. This kind of ventilation system is efficient and performance.
To install the hood in the bathroom, require fans with bearings or elements on the sleeves. The latter option is more optimal, because a device of this kind is virtually silent and does not involve significant financial investment.
Fan connection method to the light switch is also in great demand. Extractor fan starts after the light comes on. You can also install an additional switch. Place of installation - wall or enclosure.
Important!If street channel ventilation system will be supplemented with filters, be aware that they will need regular grooming. They will have to change from time to time, because the contaminated filter will prevent the sufficient passage of fresh air. Substances which are present in the lead to the proliferation of pathogens.
Thanks to modern technology, you can supplement the hood sensors humidity. Their principle is as follows: as soon as the humidity level reaches a predetermined setting, the system will immediately come into effect. There is in this embodiment, a significant drawback. For example, an extract can work at a time when its operation is not necessary.
ventilation systems can also be supplemented by a motion sensor. The device starts to work as soon as a person comes to a room. The principle of operation is the same as when you connect to the light switch, but in this case the sensor is much higher.
Tip!The ventilation system can be supplemented with a timer, which will delay the process of inclusion after exiting the premises.
Installing ventilation with their hands
When choosing a fan, we must consider that the noise level must be a maximum of 35 dB. The fans are classified depending on the design:
- axial;
- centrifugal;
- centrifugal axis;
- diametric.
Axial fans are relevant in the event that the system does not channels. Centrifugal high performance, but the work is quite noisy. Centrifugally network device is lightweight, does not emit loud sounds and high performance.
As air can be used:
- corrugating the pipe;
- box profile;
- product of plastic (circular or rectangular).
If forced ventilation type is installed in the bathroom and other rooms in the house will be regularly aired, should prefer a simple system without channels. Before installing the fan, you need to turn off the electricity.
Typically, the device has terminals for fastening. To connect it to a power source requires a new two-core cable. As for the installation of ventilation throughout the house, the special equipment required for this purpose. Its location can be an attic or utility room.
The equipment is a unit which provides a supply of clean air and polluted output. Additional its functions - filtering and heating. To calculate the power, you need to take into account the number of people who live in the house, its size, the material from which made the wall. Often enough 150-600 cubic meters / hour.
Modern devices are collected on the basis of the designer and can be decorated by suspended ceilings. If ventilation is properly selected and installed, it has a positive effect on the room climate. Special attention should be ventilation in the bathroom. The doors to the rooms, as a rule, rarely open, humidity index them quite large. In order to eliminate the appearance of mold on the walls, not to develop the fungus, it is necessary to work on the installation of an efficient exhaust system.
