- In the sauna, almost all rooms are modest in size. In the case of rooms with small dimensions, one needs to be guided by such a ventilation scheme, so that it provides air renewal approximately every quarter of an hour, at least. For a sauna, this is considered the limit.
- Design and installation should consider and eliminate all risks of drafts or vice versa, zones with stagnant air. [/ Box]
Typical schemes of the
ventilation system Mechanical
It is considered the most efficient, but also expensive. You will need valves, filters, diffusers, a noise suppressor and a number of other circuit elements. An example is shown in the figure:
Natural
For the device with your own hands - the easiest version of ventilation.
But this concerns only the installation process, since high-quality air exchange can be ensured only with accurate engineering calculations. In addition, there are quite a few shortcomings in this scheme. For example, the dependence on the direction and strength of the wind.
Supply and exhaust
In terms of "efficiency + final cost of installation + own" - the best engineering solution.
With the organization of ventilation according to this scheme and we will understand in more detail.
Design and operating principle of the
circuit If the reader understands the principle of ventilation in the sauna, the author's task is completed. Any owner will cope with the installation of the system with their own hands, without involving specialists. Next, we will give general recommendations on the design of the scheme and technology of work.
Supply openings
In the case of a steam room, they must be installed in the lower part of the walls and in the vicinity of the furnace. Why? First, the cold air coming from the street will heat up faster. Secondly, this feature of the scheme excludes its entry into the zone where the person takes the procedure.
If a small gap( about 50 mm) is left between the floor covering and the door leaf during the installation of the box, this will additionally increase the efficiency of air exchange between the rooms.
Extraction
The intake port of the air outlet channel, regardless of the chosen scheme, is always arranged strictly opposite the supply air, that is, on the opposite wall of the room. Depending on its specificity, such "receivers" can be two( in the steam room - necessarily).The first - not less than 100 cm from the level of the floor covering, the second - to remove air from the sauna outside - under the ceiling. Both are connected by a box. To exclude the influence of rose winds and the height of the fan pipe, a fan should be installed in the hood.
The peculiarity of the circuit is that in both channels - inflow and outflow - it is necessary to install adjustable flaps. They are called shutters, gates. It is with the help of such devices that the necessary microclimate is maintained in any of the rooms.
How does the ventilation circuit in the thermostat
Ventilate
All the latches and doors are completely open, the fan is on. It's enough 5 - 10 minutes, and in the sauna the air is completely renewed.
Heating
The doors and flaps of the exhaust duct are closed and the supply duct remains open. This makes it possible to quickly warm up the room to the required temperature with a minimum fuel consumption for the furnace.
Taking procedures in the sauna
The exhaust flap opens slightly, but only at the lower opening. What does it give? The circulation of streams begins, thus the heated air and remains in area of a ceiling. Consequently, the temperature in the steam room is maintained unchanged. And this does not stop the air renewal. As a result of the operation of the scheme, the most favorable microclimate with a significant fuel economy, that is, full compliance with the requirements of paragraph 1.1.
Common mistakes in the self-ventilation device
- Installation of only one air vent hole from the sauna, albeit with a gate, under the ceiling. This drawback of the scheme is fraught with the fact that the heated air will be rapidly removed outside. Consequently, the process of regulating its temperature in the steam room will become more complicated, and fuel consumption will sharply increase.
- The location of all the holes( inflow, exhaust) at one height from the floor. It is difficult to judge the effectiveness of the scheme( although the air exchange will be minimal), but the fact that the draft is provided is unequivocal.
- The section of the exhaust duct is smaller than the inflow. Air exchange in the sauna will be difficult. How to choose the optimal parameter for any ventilation scheme? Recommended ratio: per 1 m3 of room - 24 cm² of duct section.
The need to organize a normal air exchange in the premises of such a specific purpose is obvious to all. Since the reader wants to understand the device, typical schemes and features of installing a ventilation system in a sauna, he a priori knows that its absence negatively affects the effectiveness of procedures and shortens the life of all structural elements by approximately 3.5 to 4 times.
How to do all the work on the installation of ventilation with your own hands, and technically competently - the topic of this article.
Standards and requirements for the ventilation scheme in the sauna
The key to success is not only in the meaningful conduct of technological operations at every stage of its installation. The master needs to clearly understand what should happen in the end, whether he can do everything with his own hands, how much time will be needed and how much the ventilation system will cost.
Basic requirements
- Constant air flow( fresh) from outside.
- The unchanging temperature in the rooms, including the high one - in the therma.
