Organization of ventilation in a private house
Before proceeding with the installation of ventilation in the house, it is necessary to study the advantages and disadvantages of various systems.
The advantages of the natural system include the following:
- installation of additional equipment is not required;
- no breakdowns, no need for maintenance;
- combination with an air conditioner.
The disadvantage is the lack of the ability to control and speed up the process, as well as the need for the presence of wind to function.
Mechanical system advantages:
- work does not depend on weather conditions;
- cleaning, heating, cooling air;
- control of the amount of processed air.
Disadvantages are high installation costs and the need for constant inspection and maintenance.
The choice of ventilation system will depend on whether the house is inertial or inertialess.
Inertia is the property of a house to maintain a given temperature for a certain time. The higher the degree of inertia, the longer the house remains warm when the heating is off. The inertialess house cools down almost immediately.
Inertial houses take a long time to warm up, as they accumulate and store heat. Therefore, in this case, it is better to use natural ventilation, since the circulation of air from the outside will not affect the rapid cooling or heating.
In inertialess houses, it is better to install a mechanical system, since it will be necessary to quickly either heat or cool the room.
In private houses, it should be borne in mind that the ventilation device for each individual type of room is different from each other.
In living rooms, it is important to ensure the flow of air by opening windows and vents, installing air valves or through slots. Outflow occurs through exhaust vents in bathrooms, bathrooms and kitchens.
In the kitchen, the inflow is provided by windows and adjacent rooms, the outflow is provided by built-in hoods. The same situation is with bathrooms, toilets, laundry and ironing rooms.
Garages, basements, boiler rooms, that is, places with an increased likelihood of accumulation of harmful toxic substances, must be equipped with a supply and exhaust ventilation system. It is necessary to install two pipes with access to the street. Fresh air will flow through one, the other draws out the processed one. The pipes should be located at different ends of the room. This is taken into account when designing ventilation in a private house.

Design features
To create a comfortable microclimate, it is necessary to determine and balance many parameters:
- the power and performance of the fans, the pressure they create, taking into account the dynamic resistance of the ventilation ducts;
- section of ventilation pipelines and their layout, taking into account building structures, location of ventilation and other equipment;
- location of exhaust and air supply points;
- composition and placement of air conditioning equipment;
- composition of monitoring and control devices, their location, connection;
- measures to reduce the noise level produced by the operating equipment, including that propagated through the air ducts.
Signs of a high-quality ventilation project can be considered:
- air circulation is established in all rooms
- silent operation of equipment and air ducts
- no drafts and cold zones
- use of energy saving technologies
- easy adaptation of the system to warm and cold seasons
By ordering a professional design of ventilation now, in the future you will be able to avoid many problems, such as: violation of the aesthetics of the interior, noise, high energy consumption, decrease in system performance.
A professional project provides for the smallest nuances of object operation and creates optimal conditions for people living or economic activity.
The ventilation system design is created at the early stages of the construction of the facility - as part of the general design work. It must take into account the requirements of fire safety and sanitary standards, and also harmoniously fit into the overall architectural composition. Timely creation of a ventilation project will allow you to create the most efficient system with minimal costs for equipment and communications.

The explanatory part contains information about the required certificates and licenses for work, coordination of the ventilation plan with architects, designers and constructors.
Ventilation design standards (SNiPs, GOST)
The design of ventilation systems is carried out in accordance with SNiP 41-01-2003 and SP 60.13330.2012. At the heart of any project is a careful calculation of system performance. Depending on the purpose of the room, air exchange can be calculated in volumetric values (m3 / h) or the frequency of complete air replacement. The performance of the entire ventilation system is determined by the performance of the supply ventilation.
For residential premises, the required volume of supply air is usually determined at the rate of 60m3 / hour per person. For the bedroom, this figure can be reduced to 30m3 / hour, since during sleep, oxygen consumption is significantly reduced. The simplest formula for calculating ventilation capacity by volume is as follows:
V = N * Vn, where:
V - ventilation capacity in m3,
N is the maximum number of people in the room,
Vn is a correction factor that determines the volume of air consumption by one person, depending on the type of room. SNiP 41-01-2003 contains tabular values:
| Object type | Naturally ventilated | Without natural ventilation |
| Manufacturing, industrial facilities | 30 | 60 |
| Public, administrative, municipal buildings (full time) | 40 | 60 |
| Public, administrative, municipal buildings (attendance - no more than 2 hours daily) | 40 | 20 |
| Living quarters, area for 1 person more than 20 m2 | 30 | 60 |
| Living quarters, area for 1 person less than 20 m2 | 3 m3 for each m2 of living space | 60 |
This table shows the calculation of ventilation based on human factors only. At production facilities, the volume of required air exchange can be influenced by:
- the nature of the technological process,
- Type of equipment,
- presence of additional sources of pollution.
When calculating ventilation performance for health care facilities, education, public catering, the supply air rate must be calculated in accordance with the requirements of the profile ND.
Air exchange is calculated individually for each room, then the numbers are summed up and rounded up - this will be the required ventilation power.
Taking into account all additional factors (household appliances, heaters, pets, etc.), the ventilation performance of residential buildings is:
- Apartments and small private houses - from 100 to 500 m3 / h
- Cottages, townhouses, small hotels - from 500 to 1000 m3 / h
- Apartment buildings, hotels, sanatoriums - from 1000 to 10000 m3 / h
Another popular method for calculating ventilation systems is multiple.The supply air volume is calculated according to the formula
V = n * Vп, where:
Vп - the volume of the room,
n is the rate of air exchange, it is:
- bathrooms - 7
- kitchens - from 5 to 10
- office premises - 3
- residential buildings - 2

Ventilation calculation method
There are various methods for calculating ventilation - calculating air exchange for people, calculating air exchange for heat surpluses, calculating air exchange for hazards. The calculation of air exchange for people is used in most cases and assumes the supply of a given volume of air to each person in the room. Each permanent workplace is provided with 60 m3 / h, and for each visitor, 20 m3 / h is provided. If we are talking about a gym, swimming pool, fitness center or dance hall, then 80 m3 / h of fresh air is laid for each athlete. Calculation of air exchange by heat surplus is used in rooms with a large number of people (for example, concert halls, cinemas, indoor stadiums, discos) or in production rooms with technological equipment that emit a significant amount of heat. The required supply air flow rate in this case is determined by the formula: L = Q / (0.335 of the removed air in the room (° С). The calculation of air exchange in terms of hazards is relevant for production sites with emissions of harmful substances. Calculation of air exchange is made on the basis of ensuring the concentration of each of the harmful substances within the maximum permissible concentration (MPC). The MPC values for each of the harmful substances are taken in accordance with the Hygienic Norms GN 2.2.5.1313-03 "Maximum permissible concentrations (MPC) of harmful substances in the air of the working area". In some cases, several factors act in the room at once - people, harm, and heat. In this case, each of the calculations is performed separately and the largest of the obtained air flows is selected.
