Natural ventilation of residential buildings: description
Ventilation with natural air motivation can occur due to two factors: the difference between indoor temperature( or air pressure difference) and wind load. The difference in temperature is created by heating various devices( cooker, heater).Wind load is due to ventilation.
In this regard, natural ventilation systems are divided into the following types: constant and periodic, channel and non-channel. Constant means frequent air supply( for example, through air valves), periodic - airing at certain intervals( through the windows, doors).
Channel ventilation in a private house assumes vertically placed ventilation ducts. Channelless or aeration is organized in production rooms and provides a multiplicity of air exchange( with certain heat dissipation).
Natural ventilation in the house, pluses and minuses
Natural ventilation in a private house has both its pluses and minuses. First, let's highlight pluses :
- Air movement in the room without using any additional equipment. Accordingly, the financial resources expended for equipment and operation are saved.
- The occurrence of any accidents is excluded, since this system is extremely simple in its work, it does not require maintenance.
- Combines with other systems( air conditioners, filters).In addition, in a country house is rarely used only one method, the popular combination of the two systems. For example, there may be natural exhaust ventilation or natural fresh air ventilation.
Among the shortcomings of are the following: weak air exchange leads to the development of favorable conditions for the development of mold and fungus, accumulation of unpleasant odors, dampness, toxins( from plastic, furniture, computer).But the most significant disadvantage is the damage to human health, because the body constantly needs clean and fresh air. That is why natural ventilation in a private house is combined with a mechanical one.
Some advice before installing and designing
As already mentioned, in rare cases only one type of system is organized in the house. Most often do combining with mechanical( exhaust or supply) .For example, in the shower rooms, kitchens or bathrooms install exhaust ducts( for the exhaust system).For the supply air, monoblock units are additionally installed, which ensure the supply of fresh air.
Before starting construction, the ventilation scheme of the house must be indicated in the design. Do it highly specialized engineers. Therefore, there are a number of recommendations and advice that are important to consider. First, ventilation rooms should be laid in the project before the construction of the .
Secondly, for effective ventilation of cellars is important to provide ventilation channels , which will be removed from the roof. Third, along with the basic ventilation equipment, the should provide for any additional split-systems or household air-conditioner .
But the important and the main advice is that any ventilation system needs to be designed and installed with the help of specialists. Do not mount monoblock equipment for air supply! Do not skimp and call the professional workers.
