Ventilation and air conditioning installation system

Ventilation is one of the most important life support systems for any home. However, when the dwelling is so tight that it resembles a thermos, there can be no question of comfort. In rooms, it is necessary to have a good air exchange. The old air, which contains a lot of carbon dioxide, must go away, making room for a new, fresh one. Because of the disturbed air exchange in the room, it becomes stuffy, the kitchen spree spreads around the house, instead of being weathered, and the humidity in the bathroom can be so increased that it is comparable to a steam bath. Swamped windows - this is the first sign of the lack of normal ventilation. With this, it is necessary to fight, because as a result of the constant impact of dampness not only furniture and interior suffers, but also human health. To avoid this, a well-planned and carefully planned ventilation installation system is required.

Features

At the moment, there are three different types of ventilation systems: natural, forced and mixed. In the latter case, some of the elements work forcibly. It is worth considering all these types in more detail, having figured out not only in their device, but also in the features of the installation.

Natural ventilation is characterized by the fact that its operation does not require electricity, that is, it is autonomous. The room is equipped with a system of purges and ventilation ducts. The difference in temperature and pressure at the beginning and at the end of the system creates a natural movement of the air masses, which some call a draft. The ventilation installation system of this type assumes the use in the design of calculations to determine the optimal points for the inflow and outflow of air.

Advantages

Natural ventilation has certain advantages, among which are:

• The creation of natural conditions that are considered to be the most suitable for a person to be comfortable inside the building;
• Autonomy;
• Low cost of arrangement and subsequent maintenance;
• Absence of details on which fungi will develop and multiply;
• Natural movement of air masses, completely dependent on weather conditions.

disadvantages

There are certain shortcomings in such a system, among which one can distinguish dependence on natural weather conditions. For example, often a strong wind becomes the cause of the emergence of reverse traction, which takes out from the ventilation duct the garbage there. The movement of air in hot weather actually stops, as the normal functioning of natural ventilation remains possible only if the temperature on the street is lower than in the room. However, it is the natural ventilation installation system that is most suitable for providing the most comfortable conditions for a person's stay. So you can exclude the risk of allergies, colds of colds and unstable blood pressure.

Application Features

Natural ventilation is used in residential buildings, both old and modern. All multi-storey buildings are equipped with ventilation ducts, which usually pass in the middle of the riser or apartment. Through the vertical ventilation duct, the exhaust air flows upward, that is, to the roof. However, in the Soviet buildings there were no supply holes. Theoretically, fresh air had to enter the room through a ventilating vent, which was necessarily available at each window, or through small cracks in the frames. The movement of air through wooden windows has a mass of positive qualities. Natural regeneration allows air to warm up even in winter, passing through windows.

Functional Testing

So, installation and installation of ventilation systems are carried out after checking the efficiency of the existing system. If you notice the first signs of stopping the work of natural ventilation in the room, then you need to check and accurately identify the place in which the problem occurred. It will not hurt to check its efficiency, often for prevention. To do this, take a sheet of paper 25 x 3 cm, bring it to the exhaust hole in the room with the windows and doors closed. If the piece of paper has swung to the ventilation hole and even stuck to it, then everything is fine, that is, the airflow is due to the cracks under the doors and windows.

Forced ventilation

Normal operation of natural ventilation is not possible unless certain rules are observed. Air and air inlets must be located on the outer wall, and on the opposite one, an exhaust ventilation duct must be placed. The ventilation installation system allows you to place the inlet valves in several places:

• Under the windowsill;
• In the upper or lower window frame ;
• In the wall next to the window.

Many modern models of metal-plastic windows are already equipped with inlet valves in the lower or upper part. Usually they are equipped with a damper and a filter, so their operation can be controlled. Installation of a supply ventilation system can also be done by placing holes in the wall. However, if the region is characterized by the severity of the winter climate, it will be a source of icy air, which causes condensation on the wall and sometimes frost. The best option is to place the supply valve under the windowsill in the immediate vicinity of the radiator. The air penetrating into the room will heat up rather quickly. Installation of heating and ventilation systems in this case should be carried out at the construction stage, that is before the beginning of interior finishing works.

Forced ventilation

A distinctive feature of this solution is the use of electricity, which drives the installed fans. The installation of ventilation and air conditioning systems in this case has certain characteristics. Forced movement can be organized in many ways:

• One-piece solution for one room;
• Monoblock system for the whole cottage;
• Combined options, which consist of air ducts in all rooms, filters, recuperators, fans, sound absorbers and other elements.

Such solutions are completely independent of the weather conditions, since the difference in pressure is formed artificially, through fans. There is no reverse traction. To clean the air of various harmful impurities filters are used, and also its heating can be made depending on the weather conditions. The installation of ventilation and air-conditioning systems in this case is a much more complicated task, since it is required to draw up a plan for placing all the elements at the design stage of the building.

Features of forced ventilation

As shortcomings of such a system, it is customary to call not only the high cost of development, creation, installation and subsequent operation, but also the fact that most elements of such a system serve as a breeding ground for bacteria. It is impossible to clean them daily, and the air passes through them constantly, carrying all kinds of bacteria into the room. Installation of exhaust ventilation system in this case brings only negative moments for people in the form of allergies, asthma and frequent ARVI.

Scope of forced ventilation

However, in some situations it is impossible to do without using such a solution. For example, in large rooms, characterized by a significant influx of people, where there is a need for a large influx of air. Installation of an industrial ventilation system is required in production facilities, auditoriums, gyms, railway stations and other places where there is a need to provide people with large masses of fresh air.

The use of such solutions has become popular in large country houses. For example, the installation of an industrial ventilation system, in particular a supply or intake port, can be done directly above a place where there is a massive crowd of people. It can be a sofa in the living room, a smoking room or some other place. At home, the natural ventilation is quite normal, except when the building is too airtight.

Installation of air conditioning, ventilation, heating systems

Competent design is one of the most important moments in solving this problem. And this concerns not only freshly built, but also restored buildings. Usually all the design work is carried out at the stage of repair or construction, as a complex complex works with a high cost is assumed. Of course, all must be exclusively qualified professionals with experience and experience in this field.

All these systems require a consistent and thorough study of all the features of the object, as well as making accurate calculations. The final design necessarily takes into account the performed calculations, the requirements of the standards and the wishes of the owner of the building. When choosing an air conditioner, attention is paid not only to the required characteristics, but also to the brand that is most suitable for the combination of parameters. It is also important to take into account the possibilities for energy saving during the operation of the finished system.

Design and installation of ventilation and air-conditioning systems must be carried out with the performance of such types of work (if you contact a specialized company):

• Development of comprehensive project documentation for ventilation, heating and air conditioning systems, as well as for electrical and automation;
• Examination of finished objects;
• Examination of equipment that is available, as well as providing specific recommendations for its use.

conclusions

The ventilation installation system is a complex task that requires a whole range of activities. The result is an effective solution that can work for many years. The choice of this or that kind of ventilation, that is, natural, forced or mixed, depends on many factors that are necessarily taken into account by professionals in the development process. Owners of the building can only express their preferences regarding the appearance of future designs, as well as how the installed system should work. An important point is the design of the visible elements of ventilation and air conditioning, which should also be taken care of in order to create a complete harmonious interior.
