Premises inside wooden houses differvery good microclimate. The fact is that logs and beams can "breathe", that is, let the air through the pores. However, in most cases, artificial ventilation in a wooden house is still necessary. According to the norms of SNiP, air in living quarters should be changed every hour in full. Therefore, natural ventilation, even in wooden rooms, may be inadequate.
At the moment, only two basic types of ventilation systems are used in the paving and log buildings:
Such ventilation in a wooden house is usedmost often, is the simplest constructively and is very inexpensive. In this case, special valves are inserted into the walls, through which fresh air from the street enters the room. Extraction in such a system is most often natural and is a normal pipe that runs through all floors. Between the rooms the air circulates through the openings and slots in the doors and walls, covered with decorative grilles.
Such ventilation is installed in the woodenhouse is elementary. First of all, chopped or paved walls are drilled with holes for valves, which can be purchased in any construction supermarket. Install them best is closer to the heating batteries. Otherwise, it will be cold in the winter. Further, "passages" for air in partitions, walls and doors are arranged. The exhaust riser with exits to the toilet and bathroom in wooden houses is usually available initially.
Of course, even such a simple system asnatural ventilation in a wooden house, must be installed with a preliminary design of the project. Calculation of the required number of valves is performed taking into account their throughput and the total volume of all premises in the house. The same applies to the riser. If necessary, special fans can be installed in it.
This is much more complicated constructivelyventilation. In a wooden house, it is usually used only if the volume of premises is very large. In the design of such a system, among other things, can include a recuperator, flexible air ducts, filters, decorative grids, adapters, tees, etc. Of course, this is the most effective type of ventilation. The principle of its work is as follows:
A recuperator is a special device,It is designed to take heat from the air when it is thrown out onto the street and give it back to the outside. Thus, the use of this structural element in the ventilation system can significantly save on heating the room. Systems with recuperator are more expensive than any others, but they are considered the most effective. With their use can be arranged effective ventilation of the bathroom in a wooden house, living room, hallway, bedroom and other premises.
At the moment there are only three main types of such devices:
Ventilation in a private wooden house is most often arranged with the help of the latest version of devices. Plate recuperators do have a huge number of advantages:
Some disadvantages of such devices areto attribute only the impossibility of moisture exchange in them. In addition, such heat exchangers have to install special valves, since in winter their plate heat exchanger can freeze.
The main feature of plate devicesis that the incoming air into and out of the room directly into them do not intersect with each other. Contact occurs through special plates. The latter is most often made of aluminum foil. This choice is due to the high thermal conductivity of this metal. Sometimes the plates are made of special plastic.
Externally, this recuperator is aA conventional box, from which several nozzles are provided, intended for fixing air ducts. They can be located either from above or from below. The air intake and exhaust fans are installed in the recuperator. At the bottom of the housing there is an opening for draining condensate. Also in the design of plate recuperators are filters and a defroster for defrosting. In a strong cold of heat, taken away from the outlet flow, to sufficiently heat the incoming often is not enough. Therefore, in the design of recuperators, the heater is also usually switched on.
Effective ventilation in a private wooden house- this, to all other, and the right choice of the company-manufacturer of the system. The most popular companies producing plate recuperators are SHUFT (Denmark), SCHRAG (Germany), ELECTROLUX, REMAK, 2W (Czech Republic). The most purchased Chinese brand can be called recuperators MIDEA.
At the moment, there are several types of ducts suitable for installation in a private home:
The recuperator is usually installed in the attic.You can also place it in the basement. Since in the wooden houses the inner covering of the walls is usually absent, the air ducts must be carried out in special decorative boxes (which are rather expensive). Sometimes they are also stretched along the interfloor overlapping. This is a cheaper way when the ventilation system is arranged simultaneously with the construction of the house. However, with this arrangement, in the event of a breakdown, it will be quite difficult to get to the elements. Below you will find an approximate scheme (ventilation in a wooden house).
So, let's look at how, in fact,a ventilation device is installed in the wooden house. The recuperator will need to be installed on an absolutely flat horizontal platform. This element of the ventilation system must be located in an easily accessible place. The fact is that the recuperator plate needs to be cleaned of dirt at least twice a year.
After the recuperator is installed,begin drilling holes in the walls. They need to be drilled in an array of wood. That is, in the center of a log or a beam. Further into the holes insert special nipples, to which the air ducts will subsequently be fixed. They need to be prepared in advance. A return-thrust valve and an adapter are attached to each branch pipe.
At the first stage, the main supply and installationexhaust ducts. One end of them is connected to the corresponding branch pipe of the recuperator, and the other to the branch pipe inserted into the wall. The pipes themselves should be attached to the ceiling and walls according to the design. It's easier to use flexible foil ducts. After the main ones are mounted, they make wiring for the premises. To each room in the house, therefore, two pipes must be brought in - supply and exhaust. Thus, toilet ventilation is arranged in a wooden house, ventilation of the kitchen, living room and other premises. Flexible ducts are mounted on special clamps. Adapter adapters and tees are used for connection of branch hoses.
Experts advise to arrange inwooden buildings and airing floors. This will significantly extend their service life. Arrangement of floor ventilation in a wooden house is very simple. In each room, in its opposite corners between the logs, ventilating grilles cut into the supply air ducts to them. Place them under the heating devices. The exhaust holes are better positioned at the top of the rooms, since the warm air used, according to the laws of physics, rises to the ceiling.
As you can see, the ventilation device in a suburbanwooden house - the procedure is not as complex as it might seem at first glance. In fact, the difficulty is only in drawing up the project and calculating the required number of air ducts, the power of the recuperator, etc. This work is best entrusted to specialists.
