Ventilation in a private home - approaches to solving a problem

Once upon a time all houses in Russia were made of wood, made of logs, and no plaster was used either inside or outside. This means that the house simply "breathed", absorbing air from the street and passing it inside. Windows and doors made of wood also did not interfere with natural air exchange. In every village dwelling there was a Russian stove, which drained the exhaust pipe through the chimney. Thanks to this, natural ventilation was carried out in a private house.

Even now, if you are interested in building a wooden house with wooden windows and doors, with the obligatory equipping it with a fireplace or stove, the problem of ventilation of such a structure simply disappears. In such a house, all processes will take place in a natural way, as in the old days. There will be a cool on a hot day, and in the cold season, a fireplace or stove will not only heat the room, but also remove stale air to the street. And if we talk about buildings not from a beam or a log equipped with very tight glass double-glazed windows, then it is necessary to decide how ventilation in a private house will be provided.

For example, you can take a cottage, built on wireframe technology. At such a house the walls do not breathe at all, as they are tight. That is why ventilation in a private house built using this technology is a special issue. In the case of a very small house, the problem is sometimes solved by installing modern windows equipped with a microventilating system. In addition, it is possible to install a supply and exhaust ventilation system. It has a very simple principle of operation, and the installation procedure is not particularly complicated. From the dwelling structure, "bad" air is forcibly removed, and a fresh one, in a similar volume, is pumped in from the street. This is done by introducing special ventilation ducts inside the walls and ceilings . That is why the question of what ventilation should be in a private house should be resolved at the design stage. For a particular room, the operating principle of ventilation must be determined individually. If you plan to build and equip your house yourself, then it's worth to consult an experienced specialist on the issues related to the selection of the optimal system. Building standards assume that ventilation in a private home can be one of the types: natural, forced or forced-supply. And then only a professional is able to choose the right type of ventilation, and also observe all the norms of air exchange.

The supply and exhaust system has a number of advantages, one of which is considered to be the possibility of using a heat exchanger in it that does not consume energy and does not require the supply of hot water. The ventilation system must be supplemented with a recuperator, which will minimize the percentage of heat loss. If you want to create a ventilation pool, then it must be equipped with an air dehumidifier. If we talk about the ventilation system with a recuperator, it is worth noting that it allows you to keep the heat even in cases when there is a negative temperature outside the window, since the air entering the house warms up and only then is delivered inside. The recuperator can only be used in combination with an exhaust ventilation system. Such a system significantly reduces the cost of heating the premises. The system works in a similar way in the summer, however in the opposite direction. So it is possible to reduce the load on air conditioners, as well as save electricity.

It is important to remember and about such an important moment as the ventilation of the sewerage system in a private house. Such a system will not allow accumulation of various gases and odors in the sewage system, which often leads to negative consequences. Installation of such a system should be done after consulting a specialist.
