Ventilation systems, their tasks, design and varieties

Today, a person spends a significant part of his life indoors. If you believe scientific research on this topic, then for urban residents this time is about 75%. At the same time, for the normal functioning of the human body, at least 20 thousand liters of air are required daily. To meet this need, and at the same time to address issues related to cleanliness, temperature and humidity levels in the room, heating and ventilation are used - specialized systems installed inside buildings and structures.

The main tasks of ventilation

Modern ventilation systems must perform the following tasks:

• maintaining the oxygen content in the room at an optimal level;
• air purification from substances hazardous to human health;
• removal of excess moisture from structural elements of buildings and houses;
• ensuring a certain mode of temperature and humidity;
• reduction of operating costs for the maintenance of houses and structures;
• providing sound insulation in the house, due to the absence of the need for ventilation with the help of windows and doors.

Development of projects and work on the installation of a ventilation system

The above list of tasks is used to determine the requirements that the designed ventilation systems must meet, after which, in fact, the process of their creation begins. In this case, the project should contain a description of all aspects of ventilation and air conditioning.

In turn, the installation of such systems includes several stages:

• manufacturing and transportation of installed equipment;
• installation;
• commissioning with parameter adjustment;
• operational and service maintenance.

The importance of a professional approach to the operation and maintenance of a ventilation system

It is clear that ventilation must work both efficiently and continuously. This requires timely and complete maintenance and repair of equipment. It is important that such work is carried out only by those who have not only qualifications, but also significant experience in this area.

Our company offers the widest range of services related to the equipment of ventilation and air conditioning systems, both in individual rooms and throughout the building, including low and high-rise residential buildings. Experienced staff, availability of modern materials and related equipment allows us to carry out each of the above stages in strict accordance with regulatory and technical requirements.

Natural ventilation

Ventilation installed today in buildings and individual rooms and houses is of two types - natural and artificial. The first option involves a complete rejection of electrical equipment. The supply of fresh air is organized by the natural factors of the external environment - wind, temperature and atmospheric pressure. The main advantage of such systems is the simplicity of design and the absence of complex electrical equipment, reliability and durability, as well as low cost. Along with their dignity, they have a number of disadvantages due, first of all, to the principle of action.We are talking about a strong dependence on the characteristics of the external environment, which are constantly changing, and in addition, about the inability to regulate the operation of such systems. It is for these reasons that natural ventilation is best suited for use in residential areas.

Artificial ventilation

It is characterized by the presence of a whole complex of equipment that allows you to remove dependence on the external environment or to solve the problem of the inaccessibility of fresh air, or to ensure that it meets certain requirements. Such systems are of two types - supply and exhaust. The first option involves supplying fresh air to the premises. In this case, the air mass on its way into it can be subjected to additional processing - cleaning, heating or cooling. In addition, fresh air ventilation can supply it to certain areas of the room. In turn, exhaust ventilation ensures the removal of air from buildings and premises that does not meet certain requirements (in terms of temperature, humidity and the content of foreign particles). As a rule, in houses, exhaust systems work in a single "bundle" with supply air systems. Moreover, their performance should be approximately equal so that the atmospheric pressure inside corresponds to similar indicators in the external environment.

Local and general ventilation

In the first case, it is used to organize the supply of fresh air to certain areas of the room, or, conversely, to remove it. Such systems are most effective at manufacturing enterprises. In turn, general ventilation is used mainly in residential buildings, and it can also be supply and exhaust. In addition, a distinction is made between type-setting and monoblock systems. Type-setting ventilation is a complex of equipment made up of various mechanisms, ranging from fans to automated control systems. They are placed in two ways - above suspended ceiling structures or separate rooms are allocated for them. Due to this, type-setting ventilation is widely used. As a rule, these are separate houses.

In turn, monoblock ventilation is perfect only for certain rooms. All components of such systems are located inside a noise-insulated enclosure. Another advantage is that there is no need for commissioning. They are carried out during the production process. In addition, one cannot fail to note another important fact, namely, monoblock ventilation, compared to its type-setting analogue, is much cheaper.

It should be noted that ventilation systems are very important for residential buildings and industrial premises. Constant air circulation allows not only to ensure the comfort of being inside. We are talking about health, which largely depends on the quality of the inhaled air, which must not only be fresh, but also clean. In a residential building, this will allow you to ensure good rest, and in an office building and at an industrial enterprise, it will significantly increase labor productivity.
