Description

The invention relates to a ventilation network for a building, preferably a detached house or an apartment building, preferably for controlled living space ventilation.

Ventilation networks for buildings, including for single and multi-family houses are known. Supply air and exhaust air are fed in and removed in separate ducts via central ventilation units via vertical shafts in the buildings and horizontal transverse distribution with ceiling vents on the floors. Fresh air is sucked in from the outside and supplied to the ventilation network. The exhaust air from the ventilation network, i.e. the air consumed in the rooms of the building is removed from the ventilation network to the outside.

The ERLUS Aktiengesellschaft product offered on the market under the product name ERLUS Via Vento is such a ventilation network for buildings, preferably single or multi-family houses. The product has a modular structure in the form of a construction kit with concrete building elements, each of which has a concrete body with an air flow space. The air flow space is in the different concrete components in the concrete body designed as a linear shaft or pipe bend. The concrete structural elements are mounted vertically one above the other in the building, forming vertical supply air or exhaust air shafts or in the transverse distributions forming horizontal supply air or exhaust air ducts.

The U.S. 2,427,780A describes a ventilation network of a building with concrete structural elements with a concrete body with a supply air flow space. In the document, a concrete body is shown which has an inlet air treatment device with a fan.

The CN 106 524 381 A describes a ventilation network for a building with concrete bodies with supply air and exhaust air ducts. An air treatment device is provided as a filter network, a sterilizer or an anion generator.

The US 4,411,255A describes a concrete structural element with a large number of ventilation ducts.

The ventilation network according to the invention is made up of concrete structural elements B in a modular manner. Several standard concrete components and one or more special concrete components are installed in the ventilation network. The concrete structural elements B, ie both the standard concrete structural elements and the special concrete structural elements, each have a concrete body 10 with at least one supply air flow space 10z and/or at least one exhaust air flow space 10a. Designs are possible in which a multifunctional channel 10m is arranged next to the supply air flow space 10z and/or next to the exhaust air flow space 10a (see Fig Figures 2 and 4 ). The special concrete components differ from the standard concrete components in that the special concrete component in the supply air flow space 10z has a supply air treatment device 10zb is arranged and / or in the exhaust air flow space 10a an exhaust air treatment device is arranged.

figure 1 shows a concrete component B, which is designed as a special concrete component. As can be seen, this indicates in figure 1 concrete component B shown has a cuboid concrete body 10 . In the concrete body 10, two shaft-like vertical flow spaces 10z, 10a are arranged parallel to one another. The flow space shown on the left is the supply air flow space 10z. The flow space shown on the right is the exhaust air flow space 10a.

in the in figure 1 A supply air treatment device 10zb is arranged in the supply air flow space 10z. An inspection opening 10zö is formed in the concrete body 10 in a wall delimiting the supply air flow space 10z, via which the air treatment device 10zb arranged in the supply air flow space 10z is accessible.

The supply air treatment device 10zb is designed as a module which is arranged in the supply air flow space 10z in a holder (not shown in detail) or in a separate recess in the inner wall of the supply air flow space. The concrete structural element B with the incoming air treatment device 10zb accommodated in the incoming air flow space 10z forms a prefabricated component which can be delivered ex works in this configuration.

The inlet air treatment device 10zb is intended as an inlet air cleaning device for cleaning dust and/or air pollutants, preferably fine dust, VOC, Signs of mold and/or odors formed. It can be based on electrostatic air treatment and/or mechanical air treatment and/or catalytic air treatment and/or ionizing air treatment, preferably ozonization, and/or UV light air treatment and/or wet-chemical air treatment.

In addition to the supply air treatment device 10zb designed as a supply air cleaning device or integrated in the supply air treatment device 10zb, a preferably optional air humidification device and/or odorization device can also be arranged in the supply air flow space.

In the embodiment in figure 1 external lines are still connected to the concrete component B. It is an external supply air supply line 11z and an external exhaust air discharge line 11a. The external supply air supply line 11z is connected to the supply air flow space 10z via a connection point arranged on the concrete body 10 . Supply air is introduced into the ventilation network from outside via the supply air supply line 11z.

The external exhaust air discharge line 11a is connected to the exhaust air flow space 10a via a connection point arranged on the concrete body 10 . The exhaust air is discharged externally from the ventilation network via the exhaust air discharge line 11a.

At one opposite figure 1 modified embodiment can be in the concrete body 10 of the concrete member B instead of or in addition to the in figure 1 in the supply air flow space 10z arranged supply air treatment device 10zb an exhaust air treatment device can be arranged in the exhaust air shaft 10a. For this purpose, an inspection opening 10aö is formed in the concrete body 10 of the concrete structural element B to the nearest outside, via which the exhaust air treatment device accommodated in the exhaust air shaft 10a is accessible. In addition to the exhaust air treatment device designed as an exhaust air purification device or integrated into it, an air humidification device and/or an odorization device can also optionally be arranged in the exhaust air flow space 10a of the concrete body 10 . The cleaning or other post-treatment of the exhaust air that is possible via the exhaust air treatment device makes sense in the ventilation network in particular if the exhaust air is at least partially recirculated in the ventilation network or certain exhaust air constituents are to be removed from the exhaust air.

The Figures 2 and 4 show the ground plan of concrete building elements, which, in contrast to the concrete building element in figure 1 in the concrete body 10, in addition to the supply air flow space 10z or the exhaust air flow space 10a, also have a multifunctional duct 10m, which is arranged parallel to the supply air flow space 10z or parallel to the exhaust air flow space 10a and is the same as the supply air flow space or the exhaust air flow space as a continuous duct that runs through passes through the concrete body. A sensor device (not shown) or a control device (not shown) or other components can be arranged in the multifunction channel 10m, which are connected to the supply air treatment device in the supply air flow space 10f and/or the exhaust air treatment device interact in the exhaust air flow space 10a. For this purpose, a through-opening can be formed in the intermediate wall, which is formed between the multifunctional channel 10m and the supply air flow space 10z or the exhaust air flow space 10a. The sensor device and/or the control device and/or an electrical connection line to the intake air treatment device or to the exhaust air treatment device can engage in this passage opening. Provision can also be made for a sensor head of the sensor device to be inserted into the passage opening or to be arranged to reach through. In the exemplary embodiment according to the invention, at least the sensor device (not shown) is arranged in the multifunction channel 10m.

From the Figures 3 and 4 it can be seen that the supply air flow space 10z and the waste air flow space 10a do not have to be formed in a common concrete component B, but that the supply air flow space 10z and the waste air flow space 10a can each be formed in a separate concrete component, i.e. in a separate concrete body 10.

Concerning the construction of the ventilation network: the ventilation network is constructed from several concrete building elements B, which are arranged vertically one on top of the other. They form one or more vertical strands, in which the supply air flow spaces 10z are aligned vertically one above the other, forming one or more vertical supply air shafts. Insofar as the components of the vertical strands arranged vertically one above the other also have exhaust air flow spaces in addition to the supply air flow spaces, vertical exhaust air shafts are formed parallel to the vertical supply air shafts through the exhaust air flow spaces. vertical Lines that consist of concrete construction elements arranged one on top of the other, which only have spaces through which exhaust air flows, only form vertical exhaust air shafts in the lines.

In each of the vertical shafts there is at least one special concrete component, in which, as explained above, a supply air treatment device 10zb is arranged in the supply air flow space 10z and/or an exhaust air treatment device is arranged in the waste air flow space 10a.

The vertical strands of the ventilation network each have at least one distributor device on each floor, which communicates with at least one of the air supply spaces and/or air exhaust spaces of the concrete building elements. Conventional air ducts can preferably be connected to the distributor devices for the purpose of transverse distribution in the floors.
