The main purpose of a ventilation system is to supply air to a room. This process can be natural or mechanical, that is, through the use of special equipment. Ventilation is necessary to meet all the needs of people in the room and to support the technological process. It helps create a good microclimate and comfort for people working in the building.
If the flow of fresh air is insufficient, people suffer from hypoxia, which affects health, mood, reduces productivity, and impacts immune function. Regular air cleaning is also necessary because harmful pollutants emitted by construction materials, interior elements, etc., accumulate over time and negatively affect the well-being of everyone in the room, especially during long periods of time.
Air exchange can only be ensured by a ventilation system that regularly rotates the air. Air enters the room in two ways:
- Natural air exchange
- Mechanical air exchange
Natural air exchange
Such air exchange is controlled by natural forces. It involves wind, temperature differences between inside and outside, and air pressure. To improve this process, exhaust ducts can be installed. The exhaust air exits through these ducts. Most people notice that such ducts are in restrooms, kitchens, and bathrooms. Thanks to natural draft created by deflectors placed on the roof of the building, the used air escapes. Consequently, fresh air exchange occurs through window and door gaps.
Modern plastic windows do not allow fresh air to enter the room, so opening windows can be considered one of the methods of natural ventilation. There are instances when dust and unpleasant odors enter through the ventilation system. Experts refer to this phenomenon as the reverse draft effect. To address this issue, it is necessary to install fans in the exhaust duct. These fans help direct used air into the exhaust ducts.
Mechanical air exchange
As mentioned above, the process of mechanical ventilation uses equipment that helps replace the exhaust air with fresh air. At the same time, mechanical air exchange is independent of external factors.
Mechanical ventilation allows for maintaining optimal microclimate parameters in a room: air filtration, dehumidification, cooling, and heating.
During construction, the question of combining natural and mechanical ventilation is often considered. However, Kliwenta specialists advise customizing the ventilation system for a specific building, as there are separate building code requirements for different types of rooms.
There are two types of mechanical ventilation: local and general. The first is designed to work in a limited area, while the second covers the entire room. This is why general ventilation is used in residential spaces.
Types of mechanical ventilation
There are 3 types of ventilation systems:
- Exhaust
- Supply
- Supply-exhaust
The difference between them lies in the process of creating pressure, which is essential for air exchange.
Parameters of ventilation systems for residential spaces
When choosing a ventilation system, you should focus on its functionality, as it must create a microclimate that meets specific requirements. There are standards and regulations for each type of space. It is also important to consider the presence of pollution sources, architectural features of the building, and other factors.
The main features of air exchange include its volume and the air exchange rate. For spaces where people live, there are specific ventilation requirements, such as:
| Type of room | Volume of air exchange per person |
| Living room, bedroom, children’s room | At least 30 m3/h |
| Library | From ½ to 1 m3/h |
| Kitchen with an electric stove | At least 60 m3/h |
| Kitchen with a two-burner gas stove | At least 60 m3/h |
| Kitchen with a four-burner gas stove | At least 90 m3/h |
| Bathroom, restroom | 25 m3/h |
| Storage room | 1,5 m3/h |
| Sports hall | At least 80 m3/h |
Components of a ventilation system
Kliwenta specialists advise their clients to install only high-quality ventilation systems. The equipment can vary, and the variety of equipment from global manufacturers allows choosing a system that meets all requirements.
There is an option to replace large equipment with compact devices that are just as functional. For example, a three-stage purification system will thoroughly filter the air, removing any toxic substances and unpleasant odors. Compact models won’t mar the building’s appearance, allowing them to fit into the design. These systems do not require the installation of air ducts, suspended ceilings, or ventilation shafts. Equipment installation can be carried out even after all renovation work is completed. Therefore, to make the right choice, it’s better to consult with experienced Kliwenta specialists.
Cost of creating a ventilation system project
It’s not worth skimping on quality when designing and installing ventilation equipment. To get an estimated cost of the experts’ services, allow Kliwenta’s engineers to review the building’s plans. After creating a mini-project, price limits will be set. Once all the details are discussed, the engineers visit the site and create a specific design, after which they can announce the final cost of ventilation installation for the building or room.
