Will stink for other purposes. Like when in the shower smells like soup? A shampoo in the kitchen? I think no.

The document says nothing about the mandatory mechanical ventilation device, it referred only to "air vents". SP 55.13330.2016 quote:

To ensure natural ventilation must be possible to ventilate the premises of the house through windows, vents, skylights and other vents.

What should be the exchange of air in a private house

According to the above document, the minimum values ​​of ventilation shall be such as:

•  smokers with constant presence of people (that is, in which people are not less than 2 hours continuously or 6 hours Total during the day), the volume of air must be completely changed once per hour;
• from the kitchen to be removed per hour of at least 60 m³ of air;
• of bathrooms, bath, shower, toilet - 25 cubic meters of air per hour;

Estimated value of the air in the premises of a country house

whether the forced ventilation is needed?

Do I need to arrange a private house forced ventilation to ensure that the recommended performance standards of ventilation in terms of regulations? Recall, the current CanPiN 2.1.2.2645-10 prescribes to have ventilation windows and vents, it deals with only natural ventilation.

4.7. Natural ventilation of premises must be carried out by the flow of air through the vents, transom or through the holes in the sash and ventilation ducts. Exhaust channel openings must be provided in kitchens, bathrooms, toilets and a drying cabinet.

The minimum volume of air per person recommended in a number of documents to be at least 30 m³ / h.

The updated revision snip 4101-2003 (introduced from 01.01.2013): 30 m³ per person or 0.35 volumes per hour.

Thus, if the area of ​​the living room is large enough, and every person in it accounts for between 10 to 20 square meters, the organization of ventilation under the current regulations are not vital needed. But if the room is for one person accounted for less than 20 square meters, mechanical ventilation is already badly needs.

For example, a bedroom of 20 square meters, in which two adults can spend the night even dispense with forced ventilation. Bedroom 18 meters - there is no one airing can not cope with ventilation problems. A small bedroom in small cottages do quite often.

conclusions

According to current regulations, in buildings where the majority of the area and has less than 20 square meters, mechanical ventilation device is needed. Also, it is strongly recommended to arrange in a large cottage with an area of ​​over 400 square meters.

But in many other cases, "the minimum amount of air" does not provide a comfortable life in a country house.

As for natural ventilation, it is better than none, but under certain conditions works very poorly, even in the absence of angles-corners-horizons and long sections of pipe. As much of its efficiency depends on the installation location of the outlet pipe. It must necessarily be above the ridge, it is necessary to choose the right size and be sure to ensure a flow.
