Installation of ventilation systems is carried out after evaluating the operational parameters of the room. The most stringent requirements for this infrastructure are presented in cases with technical facilities, which include boiler rooms. In addition, the need for stable and moderate updating of the air environment also extends to bathrooms and kitchens. In this regard, gas ventilation in a private house is of particular importance, which can cover several rooms at once. Depending on the conditions of use of gas equipment, the appropriate design of the air exhaust system is also selected.
Forced ventilation
Manufacturers of gas equipment usually recommend that as little equipment as possible be installed in the same room with such units. Nevertheless, the need to ensure the proper level of air renewal forces many homeowners to use supply air valves. Strictly speaking, this is forced-type gas ventilation, but in terms of the intensity of pumping flows, it is less effective than traditional representatives of systems of this class. We are talking about valve models with the ability to adjust the throughput.
The user can independently set the operating parameters of such devices with orientation on the operation of the stove or boiler. As for the installation of valves, they are usually placed at a height of two meters with respect to the floor. Also, gas ventilation in the form of valves should not be placed in the windows, since interference in the device of openings in most cases negatively affects the insulating properties of the room.
Exhaust ventilation
Not so long ago, natural ventilation was the only way to ventilate technical rooms. Again, in accordance with the regulations, it is not recommended to use equipment for forced air flow. In modern new buildings, which are characterized by a high level of sealing, natural ventilation can not cope. This does not mean that it is necessary to use additional supply and discharge means, but the ventilation for a gas boiler, for example, must be improved due to air ducts. It is also allowed to combine channels from technical rooms with walkways leading from the bathroom and kitchen. The main thing is to ensure sufficient intensity of natural air exchange.
Combined ventilation
The best solution for a house with airtight openings can be a supply and exhaust ventilation unit. This is a rather complicated technical tool, but one cannot do without it if the natural ventilation function cannot provide circulation in the required volume. So, this type of unit consists of exhaust and supply fans, an electric heater, filters and a plate type heat exchanger. The advantages of such a system include the function of regulating the temperature of the incoming air. Indeed, the combined gas ventilation provides the flow of the main air mass. At the same time, the user can count on extensive control capabilities of equipment, since modern supply and exhaust systems are equipped with electronic control systems.
Ventilation in the boiler room
A room designed to be equipped with a gas boiler must be equipped with both exhaust and supply systems. Another thing is that they can be represented either by a single aforementioned unit, or by separate communications. Again, forced ventilation equipment should be avoided - in its pure form it is not allowed for installation in such rooms. In the design process, both systems should be calculated. So, exhaust ventilation of a gas boiler should provide threefold complete air exchange per hour. In turn, the supply ducts, in addition to the exhaust volume, must also take into account the intake of air consumed for gas combustion. It is important to remember another feature of the supply of ventilation equipment to the boiler room. Since there is always a danger of explosions and fires during the operation of gas units, local communications must have special protection in the form of insulation.
Features of ventilation in the kitchen
Separate requirements apply to air exchange systems in the kitchen. First of all, for rooms where there is a gas stove, a supply valve can be provided with the ability to adjust the volume of passing flows. If the kitchen has a gas boiler, then you can restrict yourself to the same valve, but without the ability to adjust the throughput. The same recommendation applies to rooms in which a coal stove is present. It is worth noting that the ventilation of the kitchen with a gas stove is largely determined by the area of the room, as well as the connection with other rooms. For example, under the condition of effective interaction of natural kitchen ventilation with other channels, the need for supply valves may disappear altogether.
Conclusion
The principles of gas ventilation are in many respects similar to those of other facilities. But there are some features. First of all, they are expressed in increasing the intensity of air renewal and inflow volumes. In addition, in each case, an individual calculation of the channel capacity is made from the point of view of replenishment of the fence coefficient. And another feature that distinguishes gas ventilation is the restrictions on the use of forced air support systems. On the one hand, this requirement is quite logical and dictated by safety standards, but on the other hand, it forces homeowners to look for more complex solutions to the problem of air exchange. In most cases, intermediate options involving the use of supply valves save the situation.
