Definitions
- the invention relates to a ventilation device for ventilating at least one room in a building according to the preamble of claim 1 .
- the invention relates to a ventilation device with a heat storage unit for heat transfer from the ventilation media flow to the ventilation media flow, with a closing and opening device for controlling the air flow paths, filter elements being provided in the air flow paths.
- Ventilation devices of this type are already known from DE 3207761 A1.
- the invention describes a ventilation device with recovery of the exhaust air heat for living and recreation rooms, offices, schools, warehouses and work rooms with a box-shaped housing that can be mounted on the wall and/or in false ceilings, with two radial fans for separate supply and discharge the air flows are provided.
- One storage package each is used as a heat exchanger for supply air and exhaust air. Depending on the switching status, the metal sheets of the storage packs are in direct contact with the supply air or the exhaust air.
- the change of direction of the air streams takes place via a controllable air flap with continuous changes in the velocity vector of the air streams within the storage packs in the area of the heat transfer between the storage packs and the air streams close to the boundary layer.
- the orientation of the air flows for supply and exhaust air in the known ventilation device are inappropriately assigned to one side for air exchange due to the arrangement within the ventilation device, so that additional work has to be done outside of the ventilation device by means of duct deflections. Additional channel deflections require additional installation space, which can be a hindrance.
- the ventilation device has two air ducts, each of which has a duct opening on the input side and an output side and are fluidically connected to one another between the associated duct openings by an air conveying device that has them, and with a closing device which, in a first operating mode, forms a first air path leading via the air conveying device one Channel opening of a first air duct with a channel opening of the other second air duct fluidically connects. Furthermore, the closing device fluidically connects the other duct opening of the first air duct to the other duct opening of the second air duct in a second operating mode to form a second air path leading via the air conveying device.
- the well-known ventilation device is structurally designed in such a way that the closure device consists of a ventilation slide, through which the respective operating modes are controlled with a rotary movement.
- the time sequence for adjusting the locking device via the ventilation slides to the selected operating mode behaves cyclically, so that an air exchange is interrupted during this period, which can have a negative effect on the air exchange and, due to the constantly changing noise, can have a disruptive effect on people in the room.
- the heat exchanger and also the filter element are flown through alternately, whereby by dividing the air flow of the aeration and ventilation medium flow through the heat exchanger in half, only half of the available storage capacities are in use, which has a negative effect on the degree of heat recovery.
- the filter element is alternately flown through by the aeration and deaeration medium flow.
- the dirt particles that have already been sucked out of the room by the ventilation media flow are introduced back into the room by the ventilation media flow.
- WO 2015/139885 A2 has also become known, which has a ventilation device for ventilating rooms in a building, with a housing. With a first side face in a building wall, to the inside of the room, and with a second side face to the outside. Furthermore, with a ventilation medium flow leading into the inside of the room through an air conveying device and a ventilation medium flow leading out of the room inside to the outside, with a heat storage unit for heat transfer from the ventilation medium flow to the ventilation medium flow and with a closing and opening device for controlling the air flow.
- the housing is separated in height by an intermediate floor and forms an upper level and a lower level, the housing being divided in length in the upper level by the closing and opening device and the lower level by means of partitions, creating two upper air flow channels and form two lower air flow channels.
- the air conveying device consists of an air supply fan for the aeration medium flow and an exhaust air fan for the ventilation medium flow and is operated continuously in an air conveying direction and connects the upper level with the lower level.
- DE 3602120 A1 discloses a method for operating a ventilation device for ventilating and venting rooms in a building, in which fans and heat accumulators are provided in the ventilation and ventilation flow of media.
- An alternating flow through the heat accumulator results in a temperature exchange of the aeration and ventilation media flow, with the alternating flow through the heat accumulator being achieved by exchanging the ventilation paths of the ventilation and aeration media flow in the upper level of the housing of the ventilation device while maintaining the conveying direction of the fans and by maintaining the air flow ducts to the blowers, the aeration and ventilation medium flow in the lower level is constantly flowed through.
- WO 2019/115254 A1 has a ventilation device for ventilating rooms in a building, which consists of a housing arranged in a wall of the building.
- a ventilation device for ventilating rooms in a building which consists of a housing arranged in a wall of the building.
- a first side surface on the inside of the building which has an outlet opening on a lower level for the ventilation medium flow of a lower air flow duct and an inlet opening for the ventilation medium flow of a lower air flow duct
- a second side surface on the outside which is on an upper level for the reciprocal ventilation media flow of the upper air flow channels each having inlet and outlet openings.
- a heat storage unit for heat transfer from the ventilation media flow to the ventilation media flow and with a closing and opening device for controlling the air flow.
- the object of the invention is now to provide a ventilation device of the type mentioned at the outset, which overcomes the disadvantages of the prior art.
- the ventilation device should improve the air performance, with good sound insulation, low inherent noise and a high degree of heat recovery.
- the housing of the ventilation device forms an upper level and a lower level separated in height by an intermediate floor. Furthermore, the housing is divided in length in the upper level by the closing and opening device and the lower level by means of partition walls, thereby forming two upper air flow channels and two lower air flow channels. Furthermore, in an advantageous embodiment, the air conveying device consists of a supply air fan for the aeration medium flow and two exhaust air fans for the ventilation medium flow or two supply air fans for the ventilation medium flow and one exhaust air fan, with the medium flow operated from one fan being continuous and that from two Blowers operated media stream is operated cyclically alternating in an air flow direction and connect the upper level with the lower level.
- Two fans are arranged along the length of the housing in the upper level, which also each form a closing and opening device with two upper air flow channels.
- a fan is formed, which has two lower air flow channels by spatial separation.
- the upper air flow ducts to the side surface of the housing on the upper level each have a heat storage unit, with a supply air filter element being assigned between the heat storage unit and the outside, which in the air flow ducts continuously full surface alternately and in opposite directions from the ventilation media flow through the Closing and opening device can be flowed through.
- the air flow channels in the lower level are constantly flowed through by the aeration and ventilation media flow.
- blowers are used to convey air.
- the fans are preferably forward curved centrifugal fans.
- two exhaust air fans and one air supply fan are described, it also being possible, as described above, for two air intake fans and one exhaust air fan to work in the ventilation device.
- the supply air fan conveys the outside air into the interior, while the two exhaust air fans convey the room air out of the interior. While the supply air fan generates a continuous volume flow, the exhaust air volume flow alternates cyclically between the two exhaust air fans. In order to implement this cyclic change, the blowers are switched on and off alternately. The operating times of the two fans overlap somewhat in order to avoid an uneven background noise.
- the second fan starts up just before the first fan is switched off, so that the increasing noise of the second fan adds up to the decreasing noise of the first fan to give a constant overall noise.
- Both blowers suck from the same air duct in which they are arranged one behind the other. This arrangement ensures an inflow in the intake chamber.
- a diffuser in the form of an air duct partition is positioned as a kind of rectifier in the air duct. This diffuser is located in the flow direction in the middle of the air duct and is perpendicular to the inflow opening of the fan. It is shaped parallel to the walls of the air duct and ends just behind the inflow opening of the first exhaust air fan, so that the intake space of the second fan remains free.
- the supply air fan advantageously has a diffuser which, in the form of an air duct partition in the air duct for sucking in the ventilation media flow, is aligned directly above the fan perpendicular to the inflow opening of the fan and adapts to the shape of the air flow channel.
- the air duct modules include regenerative heat exchangers and filters mounted at the extreme end of the air duct.
- the filters sit between the storage stones and the opening to the outside and protect the device components from dirt. After removing the front profile, the air duct modules and the foam air ducts can be completely removed, the filters can be changed and the housing can be cleaned if necessary.
- the type of air movement in the unit differs from the room side to the outside. While the air in the air ducts on the room side continuously moves in the same direction, the flow directions in the air ducts on the outside alternate. This alternating air movement is generated on the one hand by the two cyclically operated exhaust air fans and on the other hand by the sliders and is necessary in order to flow through the storage stones alternately. Depending on the air direction, the storage stones are then flown through either on the pressure side or on the suction side.

- the weight is shared among the components, which is a further advantage of assembly and disassembly.
- the heat storage unit 11 cools down. With the subsequent flow through of the ventilation media stream 10 from the inside 5 of the room to the outside 7, the heat storage unit 11 cools the ventilation media stream 10 and heats up in the process. When the direction of air flow is reversed again, the heat storage unit 11 then acts like a heat exchanger, heating the sucked-in air and cooling itself down again in the process.
- the heat storage units 11 according to FIGS. 4, 7 and 12 in the plan view and in FIG. 2 in the front view, are of the same design, which prevents confusion during assembly and which has a positive effect on the balance ratio for the functionality during the operating state of the ventilation device 1.

- a closing member which is formed by a ventilation slide 42 for opening and closing the air flow channels 17, 18 for the ventilation and exhaust media flow 9, 10.
- an opening 39 is provided for a permanent air flow path of the ventilation medium flow 10, with an opening 40 being formed by a ventilation slide 41 for opening and closing the air flow channel 20 for the ventilation medium flow 9.
- the ventilation slides 41, 42, 42' are operated in a correspondingly quick closing and/or correspondingly quick opening manner via a rack and pinion drive 45 to generate an almost continuous flow of air.
- the end positions of the ventilation slides 41, 42, 42' which at the same time form the closed or an open state of the air flow channels 17, 18 assigned to the upper level 14 and the lower level 15 of the air flow channel 20 and thus influence the ventilation and ventilation media flow, are on located on the respective sides of the fans 21, 22 and 22'.
- the rack and pinion drive 45 increases the effect of the closure when the ventilation slides 41, 42, 42' change direction and thus the reliability of the drive system of the ventilation device 1.
- the closing and opening device 12 preferably has an electric motor drive which is directly connected to a spur gear 47.
- the ventilation slides 41, 42, 42' can be controlled separately from each other by arranging a drive on each spur gear 47, so that the operating state of the ventilation device 1 for ventilation or, for example, for the complete closing of an air path, can be selected via the control unit 34.
- the ventilation device 1 is then completely closed the ventilation slide 41, which is located in the lower level 15 next to the supply air fan 21.
- the drive is thus transmitted to the ventilation slides 41, 42, 42' via the spur gear 47, which is operatively connected to the control unit 34, which in turn is operatively connected to the toothed rack 46 arranged on the ventilation slide 41, 42, 42' and enables a linear reciprocating movement of the Ventilation slide 41, 42, 42 'permitted.

- the ventilation slides 42, 42' change from one side 4 to the other side 6 of the housing 2, so that the heat storage units 11 arranged are flown through alternately.
- the ventilation slide 41 remains open when the ventilation device 1 is in operation.
- the closing and opening device 12 is used in two fixed positions next to the blowers 21, 22, 22' without structural changes.
- the ventilation slides 42, 42' have different end positions during the operating state with a cyclic change of direction or in the case of the ventilation slide 41 for opening or closing the entire ventilation device 1 relative to the respective side surfaces 4, 6 of the housing 2. While the ventilation slide 42 arranged in a first operating state of the ventilation device 1 is in the end position of the open ventilation media flow 9 and the one heat storage unit 11 flows through it, the other ventilation slide 42' arranged on the ventilation device 1 in the end position of the opened ventilation media flow 10 ensures a flow through the other heat storage unit 11 . When the end positions of the ventilation slides 42, 42' change, a second operating state occurs, so that the respective heat storage units 11 are flown through from the opposite direction due to the change in direction of the ventilation media flow 9, 10 in the upper level 14.
- the electric motor drive not shown in the figures which is arranged on the respective ventilation slides 41, 42, 42′, controls the ventilation slides 41, 42, 42′ separately from one another, so that the operating state of the ventilation device is for ventilation or, for example, for complete closure selected via the control unit 34 can be.
- the control unit 34 has a circuit board on which all driving components are electrically connected. All electronic components, eg also sensors and all movable driving components are arranged in the technology module 32 so that only the technology module 32 can be removed from the housing 2 of the ventilation device 1 by an authorized specialist, for example for maintenance purposes of the above components.
- the fans 22, 22' of the air conveying device 8 which work continuously in one direction of rotation during the operating state, are radial fans which achieve a suitable nominal volume flow, high pressure stability and a volume flow that is as constant as possible.
- the continuous operation also leads to relatively low operating costs and protects the air conveying device, so that it works with little wear and almost silently.
- the blowers 22, 22' are offset from one another in the technology module 32 on the upper level 14.
- the fan 21 on the other hand, is fastened in the technology module 32 on the lower level 15 .
- the arrangement of the fans 21, 22, 22 'offers enough space for easy assembly and for sufficient insulation material for insulation, but also the size determination of the fans 21, 22, 22', which means that the fans 21, 22, 22' and a long course of the air flow channels 17, 18, 19, 20 with an aerodynamic course for the sound-absorbing effect is achieved.
- the insulating material thus lines the air flow channels 17, 18, 19, 20 or forms the air flow channels 17, 18, 19, 20.
- the inside of the housing shell of the housing 2 is at least partially lined with an insulating material. Due to the insulation, the ventilation device 1 has an acoustic—to avoid the transmission of structure-borne noise and noise from the outside—acoustically, mechanically and thermally dampening effect.
- the housing 2 protectively and compactly encases all functional components of the ventilation device 1, which can be easily and quickly installed and dismantled in the housing 2 in a fixed position and displaceable.
- the integrated functional components in the housing 2 are completely concealed when installed. Possible contamination, which can contribute to an impairment of the life of the ventilation device, are excluded by the sealed connection of the housing 2.
- the filter elements 23, 28, which belong to the air duct module 33, can also be simplified by separating the technical module 32 and allowing non-technical persons to move them out of the housing 2 for possible maintenance and clean them if necessary.
- the housing 2 has the outlet opening 26 for the ventilation medium flow 9 and the inlet opening 27 for the ventilation medium flow 0 on the side face 4 to the inside 5 of the room.
- the inlet and outlet openings 25 and 24 for the aeration and venting media flow 9, 10 are directed toward the outside 7.
