Description

Ventilation system

The invention relates to a ventilation system for a room according to the preamble of claim 1. When a ventilation system is spoken of in this application, it always means a ventilation system by means of which both outside air as supply air into a room and exhaust air as exhaust air can be transported in one room.

A generic ventilation system is known from EP 2 850 273 B1. In this known ventilation system, a ventilation device for docking to a frame of a window or door is described, in which two flow channels each provided with a fan are guided over a heat exchanger in such a way that heat is transferred between the exhaust air sucked in from the inside of the room to the outside outside air sucked into the room is made possible.

The object of the invention is to create an improved ventilation system with a high level of efficiency, ease of maintenance and adaptability to different installation situations.

This object is achieved by a ventilation system with the features of claim 1. Advantageous refinements of the invention are specified in the related subclaims.

The ventilation system according to the invention is characterized by a high degree of modularity of the ventilation device, which enables simple installation, simple maintenance and simple, tool-free and non-destructive replacement of

Components enables. It stands out over the prior art characterized in that the ventilation device forming a core of the ventilation system has at least three housing sections divided essentially transversely to the main flow direction of the air in the flow channels.

The ventilation system according to the invention thus enables, for example, a simple removal and installation or replacement of filters, fans or blowers, a heat exchanger or other components. Removal and installation can be done for maintenance or repair purposes or to bring the ventilation system up to date with the latest technical developments by upgrading individual components.

Furthermore, the ventilation system according to the invention is characterized by a great variability of the installation and connection options, which can be found in the

reflects numerous embodiments shown in the figures.

In the ventilation system according to the invention, at least one of the blowers or fans for conveying the outside air and / or the exhaust air is on the

Interior side facing away from the flow channels arranged. In this way, the sound emanating from the fans is effectively attenuated by means of other parts of the ventilation device located between the fans and the interior. In addition, at least one silencer can optionally be arranged in at least one of the flow channels, which silencer ensures further attenuation of the sound transmitted to the interior.

The ventilation system according to the invention particularly preferably has a preheating and / or cooling register in the first flow channel near an outside air inlet. This enables year-round continuous operation regardless of the temperature and / or the humidity of the outside air, the heat exchanger being automatically balanced and always kept frost-free.

The heat exchanger used in the ventilation system according to the invention is preferably designed as an enthalpy heat exchanger. This eliminates the problem of condensate discharge in the ventilation system according to the invention. In a In a particularly advantageous embodiment, it is provided that the flow channels with their sections assigned to the heat exchanger in one

Countercurrent arrangement are arranged. Overall, this increases the efficiency in such a way that around 85% of the thermal energy in the exhaust air can be transferred to the outside air.

In an advantageous embodiment it is provided that at least one filter is arranged in the first flow channel and / or in the second flow channel near the inlet of the outside air or the exhaust air. The filtering of the outside air and the exhaust air ensures that the ventilation system in the area of the

Heat exchanger or the fan is effectively protected from contamination.

In addition, only cleaned outside air is fed into the interior through the filter. Due to the modular design of the ventilation unit, the filters are also very easy to replace or clean.

In a further advantageous embodiment it is provided that an electronic control for the ventilation device is arranged in one of the housing sections. The coupling of the signal lines and the power lines between the electronic control and the electrical components, such as the fans, is preferably carried out automatically when the modules are inserted into the housing sections, for example by means of spring loaded contacts. Alternatively, the coupling of the electrical lines can also be established by plug connections, the voltage-carrying contacts of which are used when the electrical components are dismantled

are designed to be safe to touch.

The electronic control is preferably in signal connection with a control device which is optionally arranged on the inside of the ventilation device facing the interior space or is wirelessly designed as a remote control. As an alternative or in addition to this, it is possible to integrate the control device - either wirelessly (e.g. via Bluetooth® or WLAN) or wired (via a LAN connection) - into a house network, so that the ventilation system can also be used as a module within a more comprehensive SmartHome control, for example using their remote control and / or an app on a smartphone

controllable, can be used.

In a further advantageous embodiment of the invention

The system provides that at least one photovoltaic module and an accumulator for storing the energy for the ventilation device are arranged in at least one of the housing sections. The generation and storage of the electrical energy required for the blower integrated into the ventilation system enables the ventilation system to operate completely independently, which means

especially in the case of retrofitting solutions in old buildings to an expensive one

Cabling can be dispensed with.

According to a first advantageous embodiment of the system according to the invention it is provided that at least one ventilation device of the ventilation system is arranged on a reveal of a window or on the inside of a wall delimiting the room or in an opening in the wall in such a way that the

Housing sections are positioned vertically one above the other. The vertical arrangement, in conjunction with the horizontal partition walls dividing the three housing sections, enables a simple drawer-like insertion or pulling out of individual housing sections for maintenance or replacement of the components of the ventilation system accommodated by these.

Thus, in the upper housing section, a fan for conveying outside air, a filter arranged near the exhaust air inlet and a near the

Exhaust air inlet arranged silencer by pulling out the upper one

Housing part can be made easily accessible for maintenance or replacement. Pulling out the middle housing part also makes the heat exchanger easily accessible. A fan for conveying the exhaust air or exhaust air can be made easily accessible by pulling out the lower housing part.

According to a particularly advantageous further development of the system according to the invention, it is provided that at an inlet for the outside air and / or an inlet for the exhaust air and / or at an outlet for the supply air and / or at an outlet for the exhaust air on at least one of the flow channels a Channel for deflecting the air and / or for conveying the air into or from an adjacent room can be arranged. This results in a high degree of flexibility in the installation of the ventilation system according to the invention, both in the case of retrofitting solutions (for example replacing windows in old buildings) and in the case of

Given new buildings. By means of the ducts, the outside air and / or the exhaust air can either be sucked in or discharged parallel or perpendicular to the window or the wall. The ducts can also be connected to an adjacent interior via openings through a wall delimiting the interior space or via air ducts arranged in a ceiling and / or in the floor of the room

be connected and thereby ensure an exchange of air there too. Such an arrangement is particularly useful and inexpensive for windowless side rooms, toilets or bathrooms, in which their ventilation takes place via a window or a wall of an adjacent room.

In FIG. 1, a ventilation system 10 according to the invention with a ventilation device 20 built into a wall 120 is shown in cross section. Instead of in a wall 120, the ventilation device 20 can also be arranged on a reveal 112 of a window 110, as shown in FIGS. 2 and 3 and numerous other figures in the following. The ventilation device 20 is preferably adapted to the height of the window 110. If the window 110 extends down to a floor 102 of a room 100 (see FIGS. 2 and 3) and / or up to a ceiling 104 of the room 100, a housing 30 of the ventilation device 20 is preferably at the height of the window 110 adapted, wherein the compensation of the additional height can also be generated by filling modules, not shown, arranged below and / or above the housing 30 and adapted in cross section to the ventilation device 20.

According to the exemplary embodiment shown in FIG. 1, the ventilation device 20 has a housing 30 with three housing sections 31, 32 and 33 arranged vertically one above the other. The housing 30 is upward through a horizontal upper Housing wall 34 and delimited at the bottom by a horizontal lower housing wall 37. Between the upper housing wall 34 and the lower housing wall 37, two further horizontally extending partition walls 35 and 36 are provided, by means of which the housing sections 31 and 32 or 32 and 33 are separated from one another. Instead of the partition walls 35, 36, the housing sections 31, 32 and 33 can also be subdivided by bottom parts of slide-in modules arranged at the same height and acting as separating surfaces 35, 36, which can be pushed into the housing 30 with holders arranged at a corresponding height. The partition walls 35, 36 or the slide-in modules are preferably provided with seals which, when inserted into the housing 30, seal against the adjacent modules or the partition walls 35, 36, so that between the housing sections 31, 32 and 33 vertically Direction always prefers one

flow-tight sealing takes place.

The housing 30 is delimited at the front towards an outer area 200 by an outer wall. The outer wall is in the area of the first

Housing section 31 is designated with 312, in the area of the second housing section 32 with 322 and in the area of the third housing area 33 with 332. The housing 30 thus forms a rack that is open towards an interior 100, into which the three individual modules of the ventilation device 20 in the exemplary embodiment shown can be inserted and removed from the interior 100. The housing 30 is also shown in the unequipped state in FIG. 34 and will be described in detail further below.

In the first housing section 31, the outer wall 312 has an outside air inlet 41 of a first flow channel 40 in the upper region. In this first one

Flow channel 40, which after the horizontal entry of the outside air continues angled downwards in the area of the outside air inlet 41, are shown in FIG

A filter 42 and a preheating or cooling register 43 are arranged one after the other in the direction of flow. This is followed by a fan 44 in the direction of flow. The filter 42 is designed, for example, as a filter of filter class F7 in accordance with DIN EN 779. The outside air then enters the second housing section 32 through an opening 3545 in the partition 35 and continues downward there in a section 45 of the first flow channel 40. In the second housing section 32, a heat exchanger 60 designed as an enthalpy heat exchanger is arranged, through which the first flow channel 40 with its section 45 running vertically downwards past the heat exchanger 60 obliquely upwards

angled section 46 runs. After reaching the top of the

Heat exchanger 60, the first flow channel 40 goes downwards with a section 47 which is angled vertically downwards and runs past the heat exchanger 60 near an inner wall of the housing 30. The section 47 of the first flow channel then passes through an opening 3647 in the partition wall 36 into the third housing section 33, where it opens horizontally at an angle and / or vertically downwards to the interior 100 with at least one

Outside air outlet 48 in this.

On the inside facing the interior 100, the first

Housing section 31 has a horizontally extending exhaust air inlet 51 in the upper area. The exhaust air inlet 51 forms the beginning of a second flow channel 50. This is passed with a vertically downward section 55 first over a filter 52 and then over a silencer 53. The filter 52 is designed, for example, as a filter of filter class F7 in accordance with DIN EN 779.

Alternatively, the filter 52 can also be formed by an easy-to-clean filter network. Subsequent to the silencer 53, the section 55 of the second flow channel 50 bends obliquely forwards in the direction of the outer wall 312.

The second flow channel 50 then enters the second housing section 32 through an opening 3555 in the dividing wall 35 and merges there with a section 56 into the heat exchanger 60.

In the heat exchanger 60, the section 56 of the second flow channel 50 runs in countercurrent to the section 46 of the first flow channel 40 obliquely downward in the direction of the inner wall 38 of the housing 30. After exiting the

Heat exchanger 60, the second flow channel 50 has a section 57 through a passage in the partition wall 36 into the third housing section 33 over. There the second flow channel 50 is connected to the suction side of a blower 54. The fan 54 is connected on the output side to an exhaust air outlet 58 extending horizontally through the housing wall 332 to the outside.

In the first housing section 31, near the inside of the housing 30 in the lower region, an electronic control 70 is arranged, which is shown in FIG

Signal connection 72 with a control unit 74 is. The control device 74 can be arranged stationary on the inside of the housing 30 or - as shown in FIG. 1 - as a wireless remote control. The control unit 74 calculates the required speed and thus the required volume flow of the fans 44 and 54 and the output of the preheating or cooling register 43 according to the temperature and humidity of the outside air, the temperature of the exhaust air and the desired temperature and humidity in the interior 100 and transmitted to the controller 70 for controlling these units.

The electronic control 70 is optionally wireless (e.g. via Bluetooth® or WLAN) or wired (via a LAN connection) in signal connection 72 with the control unit 74. The control unit 74 is optionally wireless (e.g. via

Bluetooth® or WLAN) or wired (via a LAN connection) integrated into a house network, so that the ventilation system 10 can also be used as an assembly within a more comprehensive SmartHome controller 76, the control device 74 or the regulator 70, for example, by means of their remote control and / or can be controlled by means of an app on a smartphone.

An accumulator 80 is arranged in the front part of the lower third housing section 33, which is supplied with electrical energy by, for example, photovoltaic modules 90 arranged on the outer surface of the outer wall 312 and / or 322 and / or 332 and is used for preferably self-sufficient electrical supply to the ventilation device 20. An additional supply of the ventilation device 20 when the charge level of the accumulator 80 is low is optionally provided. If the ventilation system 10 is installed in a room-high window or next to a door, the filling modules arranged below and / or above the housing 30 for height compensation can be used very well to accommodate additional ones Accumulators 80 and for attaching additional photovoltaic modules 90 are used.

In the figures 2 to 33 different installation situations of the

Ventilation system 10 according to the invention shown. Due to the wide range of installation options, both in the area of retrofitting when replacing windows or expanding the windows, for example in old buildings, as well as in the area of original equipment, especially in modern low-energy houses or zero-energy houses, the system according to the invention is versatile and easy to install. Due to the modular design, individual

Components can be replaced with other or new components with little effort.

In FIGS. 2A and 2B up to FIGS. 33 A and 33 B, the figure with the letter A shows a schematic front view and the figure with the letter B shows a cross-section of a specific installation situation.
