Ventilation kit for individual ventilation of internal bathrooms and toilets for connection on collective ventilation pipes

description

Bathrooms and toilets, including kitchens, are predominant in today's residential construction arranged inside without ventilation. The ventilation of these rooms can be achieved in different ways. Fireplaces without tiö ^ chanische ventilation have the simplest mode of action. they work based on the principle of gravity, but have the disadvantage of taking up a lot of space and venting only under favorable conditions satisfactory. While in winter a strong suction that is no longer desirable can arise, a higher outside temperature does not allow any More air supply, so that the ventilation is often insufficient, especially in summer.

In the course of the last few years, therefore, mechanical ventilation has always been more has been introduced. With this method, in turn, there is both individual ventilation and collective ventilation or central ventilation known. Individual vents work in such a way that each bathroom or toilet to be ventilated has its own ventilation device. The exhaust air is guided out into the open by each fan. The area of application is limited due to the separate exhaust air duct for economic reasons almost exclusively on ground-level or very low-storey buildings. Collective ventilation can be via., Collecting shafts or a larger number of collecting lines Centrally arranged roof ventilators from the connected Bathrooms and toilets suck in exhaust air and pull it up through the above-mentioned collecting lines. The prerequisite for this is that the roof fan is constantly is in operation, at least whenever from the connected Baths and V / C also only one of them is used. For economic reasons, this type of ventilation is the most continuous operation spread and was incorporated into the regulations that roof ventilators must be able to run continuously. The regulation also contains information relating to the characteristics listed above about individual ventilation. Due to the continuous operation of the roof ventilators, the building is constantly receiving large amounts of air from all connected bathrooms and toilets withdrawn, which has to be compensated for in the winter months by increased heating. Individual fans can therefore be significant

Bring heating savings compared to roof fans.

In the case of multi-storey exhaust air shafts of the roof fan collection systems there are naturally different suction volumes in the individual Shot. The top floor has a larger intake volume en-brjoiuiueij, as the uppermost floor, tei which <?.? r the static pipe resistance that occurs between the top and bottom storeys must also be overcome. Through appropriate mechanical narrowing of the suction openings is achieved that the suction volume is steadily throttled from floor to floor upwards and thus a more even ventilation should occur. In practice, such patience becomes both time consuming and demanding Adjustment of the entire system with today's piecework design and the steadily rising costs are often only fleeting and thus inadequate, sometimes not carried out at all. The consequence of this is insufficient ventilation of the lower Geacho and excessive air exchange, associated with drafts, on the top floors. In addition, it can b-i extreme attitudes towards whistling noises

In addition, the Samrrel systems were for the conventional construction, namely all bathrooms and 7JC vertically below each other, designed. In the case of terraced residential complexes, which are becoming more and more common, They can only be used with great effort due to the shift in the floor plan, e.g. through a separate earth duct, which collects all of the downward ventilation ducts of the individual bathrooms and toilets and leads them to the common chimney, which then in turn leads to the outside at the highest point of the residential complex.

The ventilation kit described below, the subject of the Registration, now combines the advantage of collecting systems with roof ventilators, namely the ^ ventilation via collecting lines without mutual disturbing influence, but without the disadvantages listed above, with the advantages of Eir, cell fans, namely the same suction quantities on all floors, as well as heating savings in winter through ventilation when necessary and extremely economical. What is new, however, is not just the intended use, i.e. the type of application within the ventilation sector, but also the execution of the ventilation kit mentioned.

The essential feature of the kit is a mounting box (1st

with front plate (2) and suction strainer (3) for installing the blower insert, as well as a ceiling wedge (4), which is set via a floor dowel (5) through its two elongated holes with a length of 40 mm it can be that the front (2) of the box is exactly flush with the shaft facing (6) to be added later. This adjusting device can therefore be used universally for all conventional visual vents. The box still contains a connection piece for the exhaust air line (7). The request to the ventilation determines the general; Viofcschrlft. provided for Each fan is provided with its own exhaust duct.

In addition to the above-described design, the universally applicable assembly box with the ceiling attachment for not yet faced, only consisting of a rear wall, is new. Schachfcrohlinge - indicated by the ceiling recess (9) - uie use of simple pipes as collecting lines (6).

The connection between the connection piece for the exhaust air line (?) And the Sasüsel exhaust air duct (8) consists of a pipe bend (ic), a connection piece (11) and a pipe branch (12). The collecting tube (8) itself can be variable in its clear width and is floor-high. The clear width of the collecting line (8) is based on the number of connections. Since the oversizing is harmless, all ventilation tasks that require up to 30 connections can be carried out economically with a few nominal sizes (such as loo, I60, 2oo, 25o mm ff). The branch piece (12) depends on the nominal diameter of the collecting pipe (8). Pipe bends (lo) and connecting piece (11) can also be replaced by a flexible pipe.

The use of simple pipes for the manifold (8) at Use of single fans, like here in the kit, is through three Merkaale marked in order to guarantee a flawless, non-reactive air evacuation. These are a.) The prevention of Sound transmission via the collecting pipe (3) to other, unfamiliar living areas, b.) Preventing exhaust air from flowing into other occupied areas when the fans there are stationary, c.) and a high compression capacity of the fan in order to reliably evacuate the exhaust air over the roof even in unfavorable weather conditions.

Since the fan itself is part of the kit, the object of this application, but not itself the subject matter, it is taken for granted. The fan type Limodor of the Pa. Limot GmbH fulfills these requirements, so that the kit also the Features mentioned above for the non-reactive exhaust air conveyance through a common collecting pipe (8) to which several fans are connected can largely meet.

The present kit is a novelty and improvement of the usual ventilation for internal bathrooms / toilets. Above all, it is very economical in terms of the system and operating costs. Especially for low and medium-storey buildings, as well as in certain cases for high-storey buildings, the reduction in investment costs has a particular effect. In addition to the cost reduction in the investment cost is the ventilation as needed, such as those offered by the kit also beneficial in the long run in its operating costs, especially if significant savings are taken into account in the heating, which to the ^in-u egensatz central roof vent systems with continuous operation In addition, the kit offers almost the same amount of air in all sorts and there is no need for any subsequent adjustment work.

With the same properties, the kit can also be used for conversions or renovation of old buildings. He's also next to Conventional new construction, particularly suitable for prefabricated installation blocks, as it provides a more efficient, cost-saving ventilation system is achieved, which does not require any reworking on the construction site and is universally applicable.
