Ventilation with air heating. Ventilation ventilation valve

It is difficult to overestimate the importance of ventilation. It is necessary both in everyday life and at work. Typically, ventilated rooms such as residential apartments and houses, industrial buildings (shop, factory), as well as working offices, offices, warehouses and much more. In any case, this is a necessary attribute wherever people are stored or located, and there is a likelihood of leakage of explosive or poisonous substances. But if in the past natural ventilation was used in most cases, then modern ventilation with air heating is popular. That's what we'll talk about in this article.

Features of natural ventilation

Natural ventilation, without a doubt, is good and has some advantages. For example, for its device there is no need to perform complex assembly work. In addition, this kind of ventilation requires little investment. The movement of air in this case is provided by the difference in temperature in the house and outside. In this case, a draft is formed, and air is drawn from the room by vertical or inclined channels. The wind can significantly help, greatly speeding up the process. In the room, air enters 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 justify hopes. The reason is that it is dependent on weather conditions, which is not its strong side. Nevertheless, correctly installed air-supply ventilation with air heating is able to solve this problem. Now we'll figure out why.

Advantages of forced ventilation

Agree, if we have the opportunity to control the flow of air entering and leaving the room, why not create more comfortable conditions for work or leisure? But at the same time it is necessary to understand that there is a natural supply ventilation, and there is a forced ventilation. We are interested in the latter, as its efficiency is higher, especially in the winter period. But in this case it is necessary to supply ventilation with air heating, since a simple fan will deliver only cold air. Often, special requirements are imposed on the purity of air. The installed additional equipment is able not only to clean it, but also to moisten it, and also to warm it up. Let's understand what air ventilation with air heating is, what are its features and how to mount it. There are a lot of important nuances and details that you need to know and carry out.

Central and individual ventilation

It must be understood that the way the ventilation is installed depends on its type. The central one is designed to supply air to the whole building. For example, a production workshop or a large office. In this case, set systems are used, which are capable of servicing buildings of any area. But the installation in this case should be carried out by professionals in a phased manner. Any error leads to the fact that the efficiency of ventilation as a whole is reduced. Some rooms can receive more air than necessary, others less.

The device for servicing one or more rooms is simpler. This kind of ventilation is mounted in a single-piece space, thus significantly reducing the noise level from the fan. Such systems are very popular, and even a beginner can install them.

Why do we need a supply air valve?

Many systems do not have such a component at all. For example, natural fresh air ventilation does not imply the installation of such equipment. Occasionally, a fan is installed, powered by wind, but its efficiency 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 air flows and condensate and mold do not form.

In all cases, the installation is carried out in the frame of the window made of PVC material. At the same time its integrity is not violated, therefore the level of passing noise will remain at the same level. Usually the hole is drilled by a special conductor at the top of the frame. Installation can be carried out both in the manufacture of a window in the shop, as well as in the finished product. In this case, the installed supply air valve does not require the removal of double-glazed units. It is very convenient and effective.

Advantages of valves in supply ventilation

The most important plus, which should be mentioned first of all, is providing the room with fresh air. At the same time, the inflow is very impressive and reaches 30 cubic meters of air per hour. But even with such volumes, temperature fluctuations are completely eliminated, especially if an air-vented ventilation air vent is used. The same applies to an important parameter, such as humidity. Waves are also absent, so do not be afraid to catch cold. After a while you will notice that the condensate has ceased to form, and you can forget about mold. At the same time, the operational characteristics of the window, such as noise and thermal insulation, remain at the same level. If you use a simple system without heating the air (heater), then no connection to the network is required. In this case, the opening of the valve is almost imperceptible, since it is executed in the same color as the window frame.

Something else about ventilation

Currently, there are 4 types of artificial ventilation rooms. All of them are mechanical and differ in efficiency and cost of installation. So, the supply and exhaust ventilation with the heating of the inflow is the most perfect. Its advantages are that, depending on the time of year, the air is then dried, then cooled. Usually, the parameters are changed using a central air conditioner. But modern air heaters mean a large number of functions. For example, air purification is available in almost all models. To do this, you use a special filter that you want to periodically change.

Briefly about the cost

To create a normal microclimate in warehouses, in production buildings and other premises, such as schools, libraries, hospitals, it is advisable to use forced-air ventilation with heating or cooling of air. However, installation in private houses or apartments of such systems can cause some doubts. First, it is due to the high cost of equipment and installation. Today, the price for air- handling units with air heating starts from 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

Installation of supply ventilation with air heating in the house must be done 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 masters. Usually the installation price is about 10% of the equipment cost. For example, the supply ventilation system "Domvent" is very popular. The domestic manufacturer produces quality valves that have several mounting options. In addition, it is relatively inexpensive, and, judging by the opinions of consumers, the quality is at a good level. In principle, this is all that can be told about the supply ventilation with heating (cooling) the flow. As you can see, the systems are very effective, but their cost makes you think.
