Air ventilation: everything you need to know
When building houses it is necessary to take into account a number of different factors that should significantly increase the level of comfort of future residents. However, there are some systems on which well-being and even people's lives directly depend. These include ventilation and air conditioning.

Necessity and purpose
First we need to say that almost all modern residential and industrial premises are equipped with similar structures. Moreover, in some rooms the installation of such systems is simply obligatory, and the ventilation itself consists of a number of different special-purpose elements.
Taking into account such features, all the work is carried out according to previously executed projects, which take into account a whole list of certain parameters, ranging from the movement of air masses to the temperature.

Purpose
- First of all, such structures are designed to remove harmful gases, vapors or other products from the premises.. Such ventilation systems are called exhaust and can be used for their work fans.

- Quite often, these structures are used to create a certain microclimate in the room.. At the same time, humidity and air heating depend on them. That is why the design outdoor temperature is very important for the design of ventilation, since it is taken as a starting parameter in the calculations.
- Some types of such products are intended for complex work with equipment that uses open fire for its work and gas or other combustible substances as fuel..

- It is worth noting that there are special-purpose ventilation.. They are developed and used in special types of production and may have a lot of modifications or special types of structures. In this case, the use of special materials or filtration systems.
Tip! Typically, projects are developed for the specific needs of certain structures or premises. Therefore, they are suitable only for single-type buildings or need an individual approach.

Consequences of poorly implemented or polluted system
- First of all, blockages or inaccuracies in the design greatly affect the air velocity during natural ventilation, and when forced to move masses, they lead to excessive energy consumption and reduce the lifetime of the nodes.
- Also, these reasons can cause a significant decrease in the quality of the air itself. An unpleasant odor appears and dust is poured from the holes in the system.

- In rooms where there is no ventilation or it is faulty, the humidity level increases significantly. This is due to mold or mildew. Such neoplasms very often cause illness or emit strong toxins.
Tip! Sometimes the usual window is not enough for the organization of the correct exchange of air masses, which means that you must either make a separate ventilation duct or install a decent system.

Design features and installation
It is worth saying that there are a lot of designs of such systems. At the same time, even two absolutely identical ventilation systems can be assembled from different materials and have an appearance that is not similar to each other. Even the flow rate of air in the ventilation can have its own parameters, which depend on the type of engine used.

Kinds
First of all, you need to mention the natural types of ventilation. This may be the usual technological holes, windows, vents, or special slits in the doors. Quite often, such systems are made independently, as they are very simple.

- Special attention should be paid to the design of the forced type of movement of air masses. They can have a very different look and are equipped with special fans. At the same time, such structures can also be installed independently, although very often they are used for industrial purposes or at particularly important places.
- Exhaust structures are most commonly used. They are mounted above hobs, stoves, tables and other points where different gases or fumes are emitted.

- Also, there are intake systems. They are responsible for bringing fresh air into the room. It is thanks to them that they often ask the question about why cold air is blowing from the ventilation.
- The most interesting are constructions designed to remove smoke or other products of combustion. They are usually manufactured together with conventional ventilation and are used in parallel.
Tip! The most optimal solution is the creation of combined systems with hoods in certain areas. However, for some types of premises, the simplest ventilation is sufficient.

Design
Usually such documentation is not done by hand. The fact is that to create a project it is necessary to make a huge number of various calculations and measurements. This may require special education or skills.

It should also be mentioned that the majority of utilities require that such documentation be created only by specialists. Even after that, it is subject to certification in certain instances and verification.
Given this attitude to the project and the fact that its execution also falls on the shoulders of specialists, it can be said that it does not make sense to talk about the installation process itself. In each case, it can be completely unique, starting from the structure itself and ending with the materials used for this.
Tip! A typical project of a residential house should already contain drawings for the manufacture of ventilation. If they are absent, then it is worth addressing this issue even before construction begins, in order to properly place the necessary highways and equipment.

Operation and prevention
It must be said that these constructions need periodic maintenance and certain rules of use. Moreover, the violation of even one clause of such prescriptions may not only lead to a disruption in work, but also cause poisoning by gases, toxins, or cause diseases.

Cleaning
A typical instruction manual for such systems strongly recommends periodic cleaning. At the same time, it’s worthwhile to say that you shouldn’t do such an operation yourself. The fact is that special equipment and personal protective equipment may be required.

Also it is necessary to make processing of highways with the help of antibacterial compositions. These include substances such as Peresvet or Samarovka. They not only disinfect the surface, but are also completely harmless to human health.
Tip! Some designs of this type do not have special inspection hatches, which means that they will have to be created independently, which will lead to additional costs. Given this, when creating a system, you need to take this feature into account.

Operating rules
For a start, it is worth noting the fact that the simplest products have practically no special requirements for operation. Their price is low, and the principle of application is quite simple and does not cause additional questions. However, we must remember that you should not clog the hole in these structures or block them with various objects.

More sophisticated products may require periodic testing for the presence of thrust, which is very important when using gas boilers or other devices that use open fire with heavy use. Also, some types of structures, especially with forced compaction, may require special treatment of the power units and the time of their work. In this case, separate instructions are created, according to which residents or service personnel are trained.
Tip! In living conditions it is best to use systems that do not require constant care or frequent preventive measures. This is due to the fact that utilities practically do not pay attention to this industry, and it is too expensive to use the services of special companies on their own.

Conclusion
After studying the video in this article, you can learn more about ventilation and its application area. Also taking into account the article proposed above, it is necessary to conclude that there are many types of such structures, but almost all of them are united by one function and almost the same principle of action.
