Ventilation is gas. Ventilation for gas boiler

Installation of ventilation systems is carried out after an estimation of operational parameters of a premise. The most stringent requirements for this infrastructure are imposed in cases with technical premises, which include boiler rooms. In addition, the need for a stable and moderate renewal of the air environment also applies to bathrooms and kitchens. In this respect, gas ventilation in a private house, which can cover several rooms at once, is of particular importance. Depending on the conditions of use of the gas equipment, the corresponding design of the air outlet system is selected.

Forced ventilation

Manufacturers of gas equipment usually recommend as little equipment as possible in a single room with such units. Nevertheless, the need to ensure a proper level of renewal of the air environment makes many homeowners use supply valves. Strictly speaking, this is a forced gas type ventilation, but in terms of the intensity of flow injection it is less effective than traditional representatives of systems of this class. It's about the models of valves with the ability to adjust the throughput.

The user can independently set the parameters for the operation of such devices with orientation to the operation of the plate or boiler. With regard to the installation of valves, they are usually placed at a two-meter height in relation to the floor. Also, the gas ventilation in the form of valves should not be placed in the windows, since interference in the opening device in most cases adversely affects the insulation properties of the room.

Exhaust ventilation

Not so long ago, natural ventilation was the only way to air the technical rooms. Again, in accordance with regulations, it is not recommended to use equipment for forced air injection. In modern buildings, which have a high level of sealing, natural ventilation can not cope. This does not mean that it is necessary to use additional supply and delivery means, but ventilation for a gas boiler, for example, must necessarily be improved due to airway shafts. It is also possible to combine channels from technical premises with passageways leading from a bathroom and a kitchen. The main thing is to ensure sufficient intensity of natural air exchange.

Combined ventilation

The optimal solution for a house with hermetically sealed openings can be a supply and exhaust ventilation unit. This is a rather complex technical tool, but it can not be avoided without it, if the function of natural ventilation can not circulate 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 this system include the function of regulating the temperature of the incoming air. Indeed, combined gas ventilation ensures the inflow of the main air mass. At the same time, the user can rely on extensive equipment control capabilities, since modern supply and exhaust systems are supplied with electronic control systems.

Ventilation in the boiler room

The room, intended for equipping with a gas boiler, must necessarily be supplied with both exhaust and supply systems. Another thing is that they can be represented either by the single block mentioned above, or by separate communications. Again, equipment for forced ventilation should be avoided - in its pure form it is not allowed for installation in such premises. In the design process, both systems should be calculated. So, the exhaust ventilation of the gas boiler house must provide three times the total air exchange per hour. In turn, the supply channels in addition to the exhaust volume should separately take into account the intake of air consumed for the combustion of gas. It is also important to remember one more feature of supplying the boiler with ventilation equipment. Since there are always the danger of explosions and fires during the operation of gas assemblies, local communications must have special protection in the form of isolation.

Features of ventilation in the kitchen

Separate requirements apply to air exchange systems in the kitchen. First of all, for rooms where a gas stove is present, it is possible to provide a supply valve with the possibility of adjusting the volume of flowing streams. If the kitchen has a gas boiler, then you can limit the same valve, but without the ability to adjust the throughput. The same recommendation applies to premises in which a coal furnace is present. It is worth noting that the ventilation of the kitchen with gas stove is largely determined by the area of the room, as well as communication with other rooms. For example, under the condition of effective interaction of natural kitchen ventilation with other channels, the need for supply valves can disappear altogether.

Conclusion

The principles of gas ventilation are in many respects similar to those of other premises. But there are some peculiarities. First of all, they are expressed in increasing the intensity of air renewal and the volume of inflow. In addition, in each case, an individual calculation of the capacity of channels is made in terms of replenishment of the fence rate. And one more feature that distinguishes gas ventilation is the limitations on the use of forced air support systems. On the one hand, this requirement is quite logical and dictated by the safety standards, but on the other hand, it forces homeowners to look for more complicated solutions to the problem of air exchange. In most cases, the situation is saved by intermediate options that involve the use of air inlets.
