Definitions

  • the air flow can either flow into the ventilation duct at the first ventilation opening, flow through the ventilation duct and flow out of the ventilation duct at the second ventilation opening, or vice versa flow into the ventilation duct at the second ventilation opening, flow through the ventilation duct and out at the first ventilation opening flow out of the ventilation duct.
  • Such a ventilation device is that the air flow in the ventilation duct flows alternately from the first to the second ventilation opening and vice versa. Therefore, such ventilation devices in the prior art are often referred to as pendulum fans. Also within the scope of the present invention, the term “pendulum fan” is used for such a ventilation device. A considerable part of the heat can be recovered by such a pendulum ventilation, since the heat accumulator is alternately heated by the air flowing out of the building and the air supplied to the building. It is therefore a solution that saves heating energy, provides fresh air and moreover ensures comfort due to preheated fresh air.
  • Such a ventilation device is known, for example, from the prospectus "Decentralized living space ventilation” from inVENTer GmbH, 07751 Löberflex, DE.
  • the heat accumulator of the known ventilation device consists, as is common practice, of a ceramic.
  • the heat content that can be stored in the heat accumulator depends on the size of the heat accumulator, the heat capacity of the ceramic and the temperature difference.
  • Pendulum ventilators for ventilating buildings are decentralized ventilation devices with heat recovery, in which the air flows through an air duct built into a wall.
  • the wall is often an outer wall of the building, i.e. part of the building envelope. In individual cases, however, it can also be a wall arranged within the building.
  • the pendulum fan is usually arranged in a core hole in the wall (i.e. a hole penetrating the masonry as such). A recess is thus made in the wall as such and the pendulum fan is arranged in the recess.
  • such an arrangement is neither optically nor energetically optimal.
  • Pendulum fans are usually arranged in groups in a building, usually in pairs and mostly in different rooms of the building.
  • one pendulum fan can be installed in the living room and in the bedroom.
  • other rooms and room combinations are also possible, for example kitchen and study or children's room 1 and children's room 2.
  • all pendulum fans have at least one fan of their own, with the control of the fans of the pendulum fans being coordinated, so that when the building an air flow is supplied via (at least) one pendulum ventilator, an air flow is discharged from the building via (at least) another pendulum ventilator and vice versa.
  • the fans of the pendulum fans are in the ventilation duct of the respective pendulum fan arranged.
  • the fans are supplied with energy via a respective electrical line, via which the respective pendulum fan is connected to an electrical energy supply, for example the usual household electricity network.
  • the control of the fans can be wired or wireless.
  • the prior art shuttle fans suffer from several disadvantages.
  • the fans generate noise. This is often unacceptable in living areas of an apartment (e.g. in a bedroom or a living room).
  • Such fan noises can usually only be accepted in utility rooms (e.g. bathrooms, toilets, kitchens, utility rooms and the like). As a result, either living spaces cannot be ventilated or the associated fan noise has to be accepted.
  • the object of the present invention is to create possibilities by means of which the disadvantages of the prior art can be eliminated or at least mitigated.
  • a ventilation device with the features of claim 1.
  • a ventilation device of the type mentioned at the outset is designed in that the ventilation device does not have a fan device.
  • the pendulum fans are always active, so they have a fan device.
  • the fan device is omitted.
  • the ventilation device is therefore a passive pendulum fan.
  • the air flow comes about as a result of a differential pressure that is present between the two ventilation openings of the ventilation duct. This avoids internal noise and the pendulum fans do not require a power connection - at least as a rule.
  • passive pendulum fans are preferably arranged in living spaces, for example in bedrooms, living rooms, dining rooms, guest rooms, study rooms or children's rooms.
  • the respective phase transformation can be a solid-solid phase transformation in the individual case.
  • a transition between a gaseous and a liquid or solid state of aggregation could possibly also be considered.
  • Ventilation devices that contain a phase change material as a heat accumulator are known as such.
  • pendulum fans the prior art involves active ventilation devices, ie ventilation devices that have a fan device.
  • the amount of heat that a phase change material can absorb through the corresponding phase change is often many times higher than the heat that a ceramic can absorb under comparable circumstances just by heating.
  • the heat capacity of the corresponding heat accumulator can be significantly increased.
  • the oscillation cycle - ie the time between switching the flow direction of the air flow - can be extended, for example to a value between 5 minutes and 10 minutes.
  • the size of the ventilation device be significantly reduced.
  • mixed approaches are also possible.
  • At least one of the heat exchangers has a single cavity and the respective phase change material is located within the cavity. This simplifies the production of the corresponding heat exchanger. In the case of other heat exchangers with a phase change material, this can of course also apply to the other heat exchangers of this type.
  • At least one of the heat exchangers encloses a residual volume that is not filled with the respective phase change material.
  • a change in volume of the respective phase change material during the phase change or also a change in volume during a temperature change of the respective phase change material preceding the phase change or following the phase change can be taken into account.
  • the remaining volume can be vacuum or filled with a gas.
  • the residual volume accounts for only a small proportion of the total volume enclosed by the corresponding heat exchanger. In any case, the proportion is less than 10%, often less than 5%, in particular less than 2% or 1%.
  • the gas can be air. However, it is preferably an inert gas, for example nitrogen or argon.
  • the ventilation device is preferably arranged in a wall of a room in the building, so that the second ventilation opening faces the room.
  • the ventilation opening facing the room is also arranged at least 1.80 m above a floor of the room, in particular above 2.00 m.
  • the ventilation device is arranged above head height in relation to the supply air entering the room. This allows drafts - that is, the perception of a draft by people in the room - be avoided to a considerable extent.
  • the ventilation device can be designed in such a way that it is arranged on the side on the edge of a window or a door or on the side next to a window or a door, the ventilation opening is arranged relatively far down on the outside and the ventilation opening on the inside is arranged higher up, so that the air in the ventilation duct flows vertically along the heat accumulator.
  • the ventilation device can be arranged, for example, on the frame of a window or door or between the frame and the construction connection or in an enlargement profile of the window or door.
  • the avoidance of perceiving the draft can be further improved by arranging an air guiding element in the region of the second ventilation opening, by means of which the air flowing out of the second ventilation opening is deflected upwards.
  • a throttle device is preferably arranged in the ventilation duct, by means of which an effective cross section of the ventilation duct can be varied.
  • Throttle devices of this type are generally known as such to those skilled in the art. You can be designed in particular as a control valve, see for example EP 3 165 702 B1 .
  • the effective cross-section can vary between “fully open” and “fully closed”.
  • the throttle device can either be operated manually or controlled by a motor or (for example as a function of differential pressure) be self-regulating. In the latter case, the throttle device can effectively Reduce the cross-section of the ventilation duct, for example, from a differential pressure of 30 Pa.
  • the throttle device is preferably actively controlled, as a result of which the effective cross section of the ventilation duct can be actively adjusted as desired.
  • the throttle device can be controlled in particular as a function of a noise level outside the building.
  • the associated sensor can be arranged, for example, in the ventilation device as such, in particular still inside the ventilation duct, but at the end of the ventilation duct that faces the outside of the building. Alternatively, the sensor can be arranged on the outside of the ventilation device or outside of the ventilation device on the outside of the building.
  • the pendulum fans of the prior art are always arranged in a core hole in the building.
  • a ventilation device according to the present invention it is not mandatory.
  • the ventilation device can alternatively also be arranged in or on a window or a door of the building. This means that it is not necessary to drill a core hole in a wall of the building. This is simpler in terms of manufacturing technology, more economical in terms of energy and more visually appealing than an arrangement in a core bore.
  • the pendulum ventilator can be arranged, for example, in an enlargement profile of the window or door.
  • the pendulum ventilator can be arranged between the frame of the window or door and the building connection. If there is a widening profile in this area, a corresponding recess can be introduced into the widening profile, for example. However, an enlargement profile is not absolutely necessary.
  • the ventilation device can be arranged in a recess that is milled or otherwise in the window frame or the casement can be introduced. In any case, by arranging it by the window or door, you use an existing building opening and can position the ventilation device in a visually appealing and discreet way.
  • the object is achieved by combining a ventilation device according to the invention with another ventilation device.
  • the additional ventilation device is constructed similarly to the ventilation device according to the invention.
  • the further ventilation device also has a ventilation duct which connects a first and a second ventilation opening of the further ventilation device to one another.
  • the ventilation duct of the additional ventilation device also has a number of sections through which an air flow flowing through the ventilation duct of the additional ventilation device flows one after the other.
  • the sections also each have a heat accumulator which is thermally coupled to the air flow flowing through the respective section (8) of the ventilation duct of the further ventilation device.
  • the further ventilation device is designed as a conventional pendulum fan. This means that the further ventilation device--in contrast to the ventilation device according to the invention--has a fan device.
  • the ventilation device it is possible for the ventilation device to have a fan device. It is possible for the fan device to have only a single fan. In this case, the fan can in particular change its direction of rotation and thus reverse the flow direction of the air. Alternatively, it is possible for the fan device to have at least one fan of its own for each of the two possible flow directions in the air.
  • Such active ventilation devices which can actively drive the air flow, are preferably in utility rooms of the building arranged in which an inherent noise is reasonable.
  • Examples of such utility rooms are bathrooms, toilets, kitchens, utility rooms or housework rooms, basement rooms, shower rooms, saunas or fitness rooms and others.
  • the combination of the ventilation device according to the invention (without fan device) and the further ventilation device (with fan device) allows the flow direction in which the air stream flows through the ventilation duct of the ventilation device according to the invention to be set in a defined manner. This is because the direction of flow in the ventilation duct of the ventilation device according to the invention follows the direction of flow in the ventilation duct of the conventional ventilation device. If the air flows from the inside to the outside in the ventilation duct of the conventional ventilation device, it must flow from the outside to the inside in the ventilation duct of the ventilation device according to the invention (and vice versa).
  • the adjustment of the flow direction and also the change of the flow direction, i.e. the targeted oscillation, is thus ultimately determined by the ventilation system of the building’s usage unit in its entirety. This is done via the fan devices in the active pendulum fans.
  • the fan devices of the active pendulum fans build up negative or positive pressure in the usage unit and in this way allow air to flow through the passive pendulum fans either from the outside in or from the inside out.
  • This configuration ensures that the direction of flow of the air in the corresponding ventilation device is always directed from the second to the first ventilation opening (i.e. usually from the inside to the outside) or the fan device is at least not activated if there is a corresponding humidity and/or concentration is detected. In this way, it can be avoided, for example, that unwanted odors - such as kitchen odors - are conducted into living rooms when the quality of the room air in an "active" room (i.e. in a room in which the active pendulum fan is installed) is critical.
