It is difficult to overestimate the importance of ventilation. It is necessary both in everyday life and in production. Typically ventilated facilities such as residential apartments and houses, industrial buildings (workshop, factory), as well as office rooms, offices, warehouses and much more. In any case, this is a necessary attribute wherever something is stored or people are located, and there is also the possibility of leakage of explosive or toxic substances. But if earlier in most cases natural ventilation was used, today forced-air ventilation with air heating is popular. It is about her that we will talk in this article.
Features of natural ventilation
Natural ventilation is without a doubt good and has some advantages. For example, for its device there is no need to perform complex installation work. In addition, this type of ventilation requires virtually no investment. The movement of air in this case is provided by the temperature difference in the house and outside. In this case, traction is formed, and air is drawn from the room by vertical or inclined channels. Wind can help significantly, greatly accelerating the process. Air enters the room through special channels. Previously, they were not, so the flows passed through the cracks in the windows and doors. But the effectiveness of such ventilation does not always live up to expectations. This is due to the fact that it is dependent on weather conditions, which is not its strength. However, properly installed fresh air ventilation with heating can solve this problem. Now we will figure out why.
Benefits of Supply Ventilation
Agree, if we have the opportunity to control the air flows entering and leaving the premises, then why not create more comfortable conditions for work or leisure? But it is necessary to understand that there is natural ventilation, and there is forced ventilation. We are interested in the latter, since its effectiveness is higher, especially in the winter period. But in this case, forced ventilation with air heating is necessary, since a simple fan will deliver only cold air. Often there are special requirements for air cleanliness. The installed additional equipment can not only clean it, but also moisturize and warm it up. Let's understand what is forced-air ventilation with air heating, what are its features and how is the installation carried out. There are a lot of important nuances and details that you need to know and perform.
Central and individual ventilation
It must be understood that the method of installing ventilation directly depends on its type. Central is designed to supply air to the whole building. For example, a production workshop or a large office. In this case, typesetting systems are used that are capable of serving buildings of any size. But the installation in this case should be carried out by professionals in a phased mode. Any error leads to the fact that the overall ventilation efficiency is reduced. Some rooms may receive more air than necessary, others less.
A device for servicing one or more rooms is simpler. This kind of ventilation is mounted in a monoblock space, due to this, the noise level from the fan is significantly reduced. Such systems are very popular, and even a beginner can install them.
What is the supply ventilation valve for?
Many systems do not have such a component at all. For example, natural ventilation does not imply the installation of such equipment. Occasionally, a fan is installed that is driven by the force of the wind, but its effectiveness in calm weather approaches zero. And the valve itself, although it is part of the ventilation, but it is installed in the upper part of the plastic window. Please note that we are talking about airtight windows, since wooden ones allow air flow, and condensation, mold does not form.
In all cases, installation is carried out in a window frame made of PVC material. At the same time, its tightness is not violated, so the level of transmitted noise will remain at the same level. Typically, the hole is drilled through a special conductor in the upper part of the frame. Installation can be carried out both in the manufacture of windows in the shop, and already in the finished product. At the same time, the mounted ventilation valve does not require the removal of double-glazed windows. It is very convenient and efficient.
Benefits of ventilation valves
The most significant plus that needs to be said first of all is the provision of the room with fresh air. At the same time, the inflow is very impressive and reaches 30 meters of cubic air per hour. But even with such volumes, temperature fluctuations are completely eliminated, especially if a forced-air ventilation valve with air heating is used. The same applies to such an important parameter as humidity. Drafts are also absent, so do not be afraid to catch a cold. After a while, you will notice that condensation has ceased to form, and you can forget about mold altogether. At the same time, the operational characteristics of the window, such as noise and heat insulation, remain at the same level. If you use the simplest system without heating the air (air heater), then you do not need to connect to the network. At the same time, the valve opening is almost invisible, as it is made in the same color as the window frame.
Something else about ventilation
Currently, 4 types of artificial ventilation are distinguished. All of them are mechanical and are characterized by efficiency and installation cost. So, the supply and exhaust ventilation with heating of the inflow is the most perfect. Its advantages are that, depending on the time of the year, the air is either dried or cooled. Typically, the parameters are changed using a central air conditioner. But modern heaters imply a large number of functions. For example, air purification is in almost all models. To do this, use a special filter that needs to be changed periodically.
In brief about the cost
To create a normal microclimate in warehouses, industrial buildings and other premises, such as schools, libraries, hospitals, it is advisable to use the supply and exhaust ventilation with heating or cooling the air. At the same time, installation of such systems in private houses or apartments may cause some doubts. Firstly, this is due to the high cost of equipment and installation. Today, the price of forced-air ventilation units with heated air starts at 40,000 rubles. It should be understood that the system is equipped with a heating element, a filter and sensors that allow you to determine the temperature in the room and the need for heating or cooling the air. The equipment operates in automatic mode. All that is required of you is to periodically change the filter element.
Conclusion
The installation of forced ventilation with heated air in the house should be carried out by professionals. Firstly, this complex equipment is not so easy to mount. Secondly, it is necessary to adjust the sensors, which is also done by the masters. Typically, the installation price is about 10% of the cost of equipment. For example, the ventilation system "Domvent" is very popular. Domestic manufacturer produces high-quality valves, which have several installation options. In addition, it is relatively inexpensive, and judging by consumer reviews, the quality is at a good level. In principle, this is all that can be said about the supply ventilation with heating (cooling) flow. As you can see, the systems are very effective, but their cost makes you think.
