Description

[0001] Air Delivery Unit

[0002] Field of disclosure

[0003] The present disclosure lies in the field of air ventilation of rooms and relates in particular to an air delivery unit, a building structure assembly with such an air delivery unit and a method for delivering incoming air to a room.

[0004] Background, prior art

[0005] Air delivery units, such as valves, are typically partially mounted inside a hole in a building structure, such as a wall, ceiling or floor of a room. Inside or behind the wall, ceiling or floor, they are connected to ventilation ducts of a ventilation system, which feed incoming air to the air delivery units and from there into the room. Often, sensors for measuring a parameter of the air, such as for example the oxygen or carbon dioxide content, are installed in the room to monitor the properties of the room air (i.e. the air being present inside the corresponding room).

[0006] There are multiple disadvantages of air delivery units being known from the prior art. For example, the sensors are often distributed randomly in the room, which is inconvenient and cumbersome. Furthermore, depending on the installation location of the sensor, the measurements can be falsified as will be discussed further below. Additionally, there are air delivery units which provide the incoming air in a disadvantageous manner to the room, namely either essentially perpendicularly to the room and thus directly onto inhabitants which causes an uncomfortable feeling, or laterally but essentially in parallel to the ceiling, floor or wall, which results over time in the formation of debris rings around the air delivery units. Lastly, many prior art devices generate high noise emissions when incoming air is being delivered to the room, which is undesirable. Summary of disclosure

[0007] It is the general object of the present disclosure to advance the state of the art of air delivery units and preferably to overcome the disadvantages of the prior art fully or at least partially. In advantageous embodiments, a compact air delivery unit is provided. In further advantageous embodiments, an air delivery unit is provided which allows to accurately determine parameters of the room air.

[0008] The general object is achieved by the subject-matter of the independent claims. Further advantageous embodiments follow from the dependent claims and the overall disclosure.

[0009] In a first aspect, the disclosure relates to an air delivery unit for providing air, e.g. incoming air or fresh air, to a room. In a second aspect, the disclosure relates to a building structure assembly with such an air delivery unit. In a third aspect, the disclosure relates to a method for delivering fresh air to a room, respectively to the use of such an air delivery unit.

[0010] As used herein, “incoming air” refers to the air being introduced into the room as new or fresh air. It is therefore different from “room air” which is already present in the room. Generally, the incoming air may for example come from the outside environment of the room or the building in which the room is located. Particularly, the incoming air may have a lower CO2 content as the room air.

[0011] In some embodiments, the air delivery unit may comprise a unit housing. In some embodiments, the air delivery unit may comprise an air deflection element. The unit housing and the air deflection element may for example define together an air flow path. The air flow path may have an inlet for introducing incoming air into the air flow path (e.g. from a ventilation duct) and an outlet for expelling incoming air from the air flow path and into the room. It may be possible that the air flow path is defined only by the air deflection element and the unit housing, or it may also be possible that the air flow path is defined by the air deflection element, the unit housing and other elements. The air flow path is suited, respectively configured, to transport the incoming air from the inlet to the outlet. In other words, the incoming air flows through the air flow path when being provided to the room.

[0012] The air delivery unit may, in some embodiments, comprise a sensor unit. The sensor unit may be configured to measure a parameter of room air in the room into which the incoming air is provided. The sensor unit may, in some embodiments, comprise a sensor. The sensor may be configured to measure a parameter of room air in the room into which the incoming air is provided.

[0013] In some embodiments, the sensor unit is arranged such with respect to the outlet of the air flow path that the room air is transported from the room to, respectively towards, the sensor by air induction. The air induction may be induced, respectively caused, by the incoming air which is provided into the room via the outlet. In other words, the air delivery unit and particularly the outlet, may be configured such that the incoming air is provided in such a manner into the room that air induction is caused which comprises the transport of room air to the sensor. Air induction refers to the effect that the incoming air being provided to the room via the outlet can entrain room air and move the room air. For example, the incoming air can be expelled laterally from the air delivery unit. Thereby, it can entrain and therefore carry room air with it. By positioning the sensor unit and the outlet in a specific spatial relationship to each other, the air induction can be exploited such that room air and preferably no incoming air is being transported to the sensor. This is highly advantageous, because on the one hand, the sensor measures room air and the measurement is not contaminated by incoming fresh air. Since the sensor is supposed to measure the parameter of the room air and not of the incoming air, providing the room air to the sensor and avoiding that incoming air is provided to the sensor avoids falsified measurements. On the other hand, this allows a constant delivery of room air to the sensor, passively and in a simple manner.

[0014] The air deflection element may typically have a center and an outer periphery. The air flow path may in some embodiments be curved. In certain embodiments, the inlet and the outlet are arranged in an angle of 30° to 100°, in particular 60° to 95°, more particular 70° to 95°, even more particular 75° to 90°. As the outlet and inlet each define a 2-dimensional plane, the angle refers to the angle between these 2-dimensional planes.

[0015] In some embodiments, the air flow path is configured such that the incoming air being provided to the room undergoes at least one, in particular only one or only two, directional change(s).

[0016] In some embodiments, the air deflection element is arranged between the unit housing and the sensor unit. Thereby, the sensor unit is covered by the air deflection element. This avoid contamination of the room air being transported to the sensor with fresh, i.e. incoming, air.

[0017] In some embodiments, the air flow path and the sensor unit may be fluidically separated from each other. This means, that incoming air cannot flow directly from the air flow path to the sensor unit, respectively to the sensor. It is understood that this does not exclude that the air cannot at some later point flow to the sensor (e.g. as room air), but it cannot do so directly and must flow through the room first upon which it becomes room air.

[0018] In some embodiments, the air deflection element and the sensor unit may be arranged such that the sensor is shielded from the incoming air being delivered to the room via the outlet. In particular, the sensor is shielded by the air deflection element itself.

[0019] In some embodiments, the air deflection element comprises a plurality of through-going slits extending from the outer periphery of the air deflection element in the direction of the center of the air deflection element. The slits may in certain embodiments only extend along a portion of the distance between the outer periphery and the center (and thus not up to the center). Such slits help to reduce the noise emissions.

[0020] In some embodiments, the air deflection element forms a concavity of the air flow path. The concavity may particularly face towards the inlet of the air flow path, or in other words when viewing from the inlet of the air flow path, the viewer looks onto the concavity. The concavity may for example comprise an externally facing region in which the air deflection element faces radially outwardly and / or towards its outer periphery. The concavity may additionally comprise an inwardly facing region in which the air deflection element faces radially inwardly and / or to the center of the air deflection element. Such a concavity allows to curve the incoming air with low noise emissions. The externally facing region may be closer to the center of the air deflection element than the inwardly facing region.

[0021] In some embodiments, the air deflection element forms a convexity of the air flow path. The convexity may particularly face towards the inlet of the air flow path, or in other words when viewing from the inlet of the air flow path, the viewer looks onto the convexity, respectively its apex. The convexity may for example comprise an externally facing region in which the air deflection element faces radially outwardly and / or towards its outer periphery. The convexity may additionally comprise an inwardly facing region in which the air deflection element faces radially inwardly and / or to the center of the air deflection element. The inwardly facing region may be closer to the center of the air deflection element than the externally facing region.

[0022] In some embodiments, the air deflection element comprises both a concavity and a convexity as described above. In certain embodiments, the convexity is arranged radially outwardly from the concavity, respectively the concavity is arranged closer to the center of the air deflection element than the convexity. Such an arrangement exploits the Coanda effect according to which the incoming air flows along the convexity and is thus not expelled in parallel to the wall, ceiling or floor, but flowing along an inclined path away from it, thereby avoiding the occurrence of debris rings.

[0023] In some embodiments, the concavity and / or the convexity are circumferentially surrounding the center of the air deflection element. That is, as seen from the inlet, the concavity forms a groove circumferentially surrounding the center of the air deflection element and / or the convexity forms a ridge circumferentially surrounding the center of the air deflection element. The groove may be arranged closer to the center of the air deflection element as the ridge.

[0024] In some embodiments, the air deflection element extends in cross-section (e.g. in crosssection being for example parallel to the delivery unit axis A as described further below) from its outer periphery as an inclination to a maximum forming an apex of the convexity. There may for example be no inflection point between the outer periphery and the maximum. In certain embodiments, the air deflection element extends in cross-section from the maximum such that it declines to a minimum forming the apex of the concavity. Typically, there is an inflection point between the maximum and the minimum. In certain embodiments, the air deflection element extends in cross-section from the minimum as in inclination towards the center of the air deflection element and / or the air delivery unit.

[0025] In some embodiments, the outlet of the air flow path is formed by a gap between the unit housing and the air deflection element. The gap may circumferentially surround the center of the air deflection element and / or the center of the air delivery unit and / or the delivery unit axis.

[0026] In some embodiments, the air flow path narrows from the inlet towards the outlet.

[0027] In some embodiments, the airflow path is gastight and / or it is free of any openings except the inlet and outlet and optionally the slits as disclosed in some embodiments herein. This may particularly apply at least for airflow rates of up to 100 m3 / h, in particular of up to 80 m3 / h.

[0028] In some embodiments, the air delivery unit further comprises a cover plate for covering the air deflection element. The cover plate may thus at least partially or fully cover the air deflection element. In particular embodiments, the air deflection element may be arranged between the cover plate and the unit housing. In some embodiments, the cover plate forms, respectively defines or comprises, an accommodation compartment. The sensor of the sensor unit may be arranged inside the accommodation compartment. For example, the sensor may be arranged adjacent, e.g. directly adjacent to, the cover plate and / or may be in contact with it. The cover plate may in some embodiments comprise, or even consist of, a plate body and a protrusion which forms the accommodation compartment and which protrudes from the plate body. The plate body may circumferentially surround the protrusion. In certain embodiments, the protrusion protrudes from the plate body in a direction facing away from the inlet and / or in the mounted state towards the room.

[0029] In some embodiments, the cover plate defines, respectively comprises, an opening which is configured such that room air can be transported through the cover plate to the sensor which may at least partially be arranged inside the accommodation compartment. In some embodiments, the cover plate defines, respectively comprises, an opening which is configured such that the sensor at least partially extends through the opening. In certain embodiments, the sensor may protrude from the cover plate.

[0030] In certain embodiments, the opening is arranged such that it faces in the mounted state into the room. The mounted state refers to the state in which the air delivery unit is mounted in a room, e.g. to a wall, ceiling or floor. In some embodiments, the opening may be arranged such that it is arranged in an angle of 60° to 95°, in particular 70° to 95°, more particular 75° to 90°, to the outlet of the air flow path. In certain embodiments, the opening lies on the delivery unit axis and / or is perpendicularly arranged to the delivery unit axis.

[0031] In some embodiments, the air delivery unit further comprises a sensor unit housing. The sensor unit housing may at least partially encase the sensor unit. In certain embodiments, the air flow path being defined by the air deflection element and the unit housing circumferentially and / or radially surrounds the sensor unit housing. The sensor unit housing may be arranged in the center of the air delivery unit and the air flow path may be arranged radially outwardly thereto. In some embodiments, the sensor unit housing may be configured to prevent that incoming air enters the sensor unit from the air flow path. For example, the sensor unit housing may be gastight. The sensor unit housing may shield the sensor unit towards the air flow path. In other words, it may be a gastight shield which prevents incoming air from entering the sensor unit from the air flow path.

[0032] In some embodiments, the sensor unit housing is releasably connected to the unit housing. The term “releasably connected” means that the sensor unit housing can be disconnected and reconnected multiple times with the unit housing without destroying the structural integrity of the parts and / or without exerting high forces. The releasable connection between the unit housing and the sensor unit may typically be a form-locking and / or force-locking connection. However, it is typically devoid of a material bonding connection, which is not considered as a releasable connection. This allows to remove the sensor unit together with the sensor unit housing from the rest of the air delivery unit. For example to replace the sensor or to replace a used battery.

[0033] In some embodiments, the unit housing defines a recess within which the sensor unit housing is mounted. The recess may for example have a tubular and / or cylinder shape. In some embodiments, the sensor unit housing has a height (extension along the delivery unit axis) which is equal or greater than the height of the air flow path (offset distance between the inlet and the outlet along the delivery unit axis).

[0034] In some embodiments, the air flow path circumferentially surrounds the delivery unit axis. The delivery unit axis extends typically perpendicularly to the inlet (i.e. the 2-dimensional plane defined by the inlet), and / or perpendicularly to the wall, ceiling or floor in the mounted state. Furthermore, the delivery unit axis is arranged in the center of the air delivery unit and / or the center of the air deflection element. In particular embodiments, the sensor unit, and in particular the sensor, is arranged on the delivery unit axis. In the mounted state, the delivery unit axis may be perpendicular to the wall, ceiling or floor. In some embodiments, the air deflection element is movable, in particular along the delivery unit axis. For example, the air deflection element may be movable such that an open area of the outlet, respectively the gap between the unit housing and the air deflection element, is adjustable. For example, by closing gap and / or decreasing the open area, the amount of air being provided into the room is decreased. Vice versa, by widening the gap and / or increasing the open area, the amount of air being provided into the room is increased. In some embodiments, the air delivery unit may comprise a drive unit, such as a motor, which is configured to drive a movement of the air deflection element and / or to adjust the open area of the outlet.

[0035] It may in some embodiments be possible that the air deflection element can be adjusted by a rotational movement with respect to the unit housing. It may for example be possible that the unit housing and the air deflection element form a threaded engagement with each other.

[0036] In some embodiments a position of the air deflection element with respect to the rotational movement can be locked, e.g. by locking means being configured to switch between a locked state in which the air deflection element is not movable and an unlocked state in which it is movable.

[0037] In some embodiments, the outlet of the air flow path is arranged such that the incoming air is laterally and / or radially expelled from the air delivery unit and optionally away from the sensor unit.

[0038] The building structure assembly according to the second aspect of the disclosure may comprise a building structure, which defines, respectively comprises, a hole. The building structure may be a wall, a ceiling or a floor of a room. The building structure assembly may further comprise an air delivery unit according to any of the embodiments as described herein. The air delivery unit may for example be at least partially inserted into the hole. This may for example be done such that the sensor unit and / or the sensor and / or the cover plate faces into the room. In certain embodiments, the building structure assembly further comprises an air duct, such as a ventilation duct, which is connected to the inlet of the air flow path.

[0039] In some embodiments, the building structure assembly is part of a room.

[0040] In some embodiments, the sensor and / or the opening defined by the cover plate faces away from the building structure. In particular, the sensor and / or the opening defined by the cover plate faces perpendicularly away from the building structure.

[0041] The method according to the third aspect of the disclosure for providing, respectively introducing, incoming air to a room and measuring a parameter of room air inside the room may comprise the steps of introducing incoming air through the inlet into the air flow path and providing the incoming air to the room via the outlet; transporting room air from the room to, respectively towards, the sensor by air induction being induced by the incoming air being provided to the room via the outlet and measuring a parameter of the room air with the sensor.

[0042] In general, the parameter may be a gas concentration, such as a CO2, VOC (volatile organic compounds) concentration, or a dust concentration (in particular a fine dust concentration) or it may be humidity. It is understood that in such cases, the sensor may be a gas sensor, such as a CO2 or VOC sensor, or it may be a humidity sensor. A VOC as used herein is any organic compound as well as the fraction of creosote, having at 293.15 K a vapor pressure of 0.01 kPa or more, or having a corresponding volatility under the particular conditions of use (see Industrial Emissions Directive 2010 / 75 / EU of the European Parliament and of the Council of 24 November 2010, article 3(45)).

[0043] The sensor unit may for example comprise a battery being configured to supply power to the sensor. Such a battery may, for example, be arranged inside, respectively accommodated in, the sensor unit housing. In some embodiments, the sensor unit may comprise a printed circuit board (pcb). In certain embodiments, the printed circuit board may be arranged between the battery and the sensor.

[0044] In some embodiments, the sensor unit may comprise a sender unit being configured to send measured data of the parameter to a receiver unit. For example, the sender unit may be a wireless sender unit, such as a sender unit relaying on electromagnetic waves.

[0045] Another aspect of the present disclosure may relate to a system comprising the air delivery unit or the building structure assembly as described in any of the embodiments herein. The system may further comprise a control unit comprising a receiver being configured to receive measured data. This measured data may either be directly provided from the sender unit of the sensor unit or it may be obtained from an intermediate storage unit, such as a cloud. In certain embodiments, the control unit may comprise a display being configured to display the measured parameter, in particular in real-time to a user. The control unit may further be configured to compare the measured parameter with a predetermined reference parameter. The control unit may further be configured to display a warning if the measured parameter falls below and / or exceeds the predetermined reference parameter.

[0046] The control unit may further be configured to compare the measured parameter with a predetermined reference parameter and if the measured parameter falls below and / or exceeds the predetermined reference parameter to automatically adjust the open area of the outlet of the air flow path and / or the gap between the unit housing and the air deflection element. The control unit may for example be configured to control the drive unit, e.g. the motor.

[0070] Brief description of the figures

[0071] The herein described invention will be more fully understood from the detailed description given herein below and the accompanying drawings which should not be considered limiting to the invention described in the appended claims. The drawings are showing:

[0072] Fig. 1 a side view of an air delivery unit according to an embodiment of the disclosure;

[0073] Fig. 2 a perspective view onto the bottom side of the air delivery unit shown in Fig. 1 ;

[0074] Fig. 3 a sectional view of the air delivery unit of Fig. 1 ;

[0075] Fig. 4 an exploded view of the air delivery unit of Fig. 1 :

[0076] Fig. 5 a sectional view of a building structure assembly according to an embodiment of the disclosure;

[0077] Fig. 6 a room and the air flow through the room when one or more air delivery units are in use. Exemplary embodiments

[0078] Fig. 1 shows a side view of an air delivery unit 1 according to an embodiment of the invention. Air delivery unit 1 has a unit housing 2 and an air deflection element 3. It can be seen that air deflection element 3 has a plurality of slits 19 which go through the air deflection element and which extend from its outer periphery towards its center. Air delivery unit 1 further has an airflow path (see Fig. 3). The air flow path has inlet 5 and outlet 6. Outlet 6 is arranged such that incoming air is laterally expelled from air delivery unit 1. Furthermore, air delivery unit 1 comprises cover plate 14 which is arranged below air deflection element 3 and covers it. Cover plate 14 consists of plate body 20 and protrusion 21 which protrudes from plate body 21 and forms an accommodation compartment for the sensor or the sensor unit (see Fig. 3).

[0079] Fig. 2 shows a perspective view onto cover plate 14 of the air delivery unit. Here it can be seen that cover plate 14 defines an opening 16 behind which sensor 8 is arranged. Thus, room air can be transported through opening 16 to sensor 8.

[0080] Fig. 3 shows a cross sectional view of air delivery unit 1. It can be seen that unit housing 2 and air deflection element 3 together form air flow path 4, which has inlet 5 and outlet 6 and is curved. Air deflection element 3 comprises concavity 9 being arranged closer to the center of the air deflection element than convexity 10. Delivery unit axis A extends through the center of the air deflection element 3 and air delivery unit 1. When viewing from inlet 5, concavity 13 is oriented towards the viewer and the viewer directly views on the groove formed. Accordingly, convexity 10 is oriented towards the viewer and the viewer directly vies of the ridge formed.

[0081] It can further be seen that when starting from outer periphery 11 of air deflection element 3, it extends in an inclination up to maximum 12, then declines up to minimum 13 at which it runs through a point of inflection (where the curvature changes from a left to right curve or from a right to left curve) and then rises again to the center of air deflection element 3 (i.e. it rises upwards towards inlet 5). Outlet 6 is formed as a gap between unit housing 2 and air deflection element 3.

[0082] It can further be seen that the air delivery unit 1 comprises a sensor unit 7 with sensor 8 which is accommodated in an accommodation compartment (see Fig. 4) formed from protrusion 21 of cover plate 14. Air delivery unit 1 also comprises sensor unit housing 17 which is gastight and prevents that incoming air from air flow path 4 can access or flow into sensor unit 7 and thus to sensor 8. Sensor unit housing 17 is releasably connected to unit housing 2. Unit housing 2 comprises a cylindrical recess 18 within which sensor unit housing 17 is releasably mounted. Sensor unit 7 can be powered by means of battery 24 which can in some embodiments also be arranged inside sensor unit housing 17.

[0083] Fig. 4 shows an exploded view of the air delivery unit 1. It comprises unit housing 2, air deflection element 3, sensor unit housing 17 (which comprises two parts being separated from each other in the shown exploded view), sensor 8 and cover plate 14. In this embodiment accommodation compartment 15 of cover plate 14 is shown into which sensor 8 can be arranged.

[0084] Fig. 5 shows a mounted state, respectively a building structure assembly 100 according to an embodiment of the disclosure. It comprises building structure 22 defining a hole into which air delivery unit 1 can be inserted. Building structure assembly 100 further comprises air duct 23 which is connected to the inlet (see inlet 5 in Fig. 3) of air delivery unit 1 .

[0085] Fig. 6 shows a room having 3 air delivery units 1 , T, 1” and the indicated flow of the air through the room. It can be seen that due to air induction of the incoming air being laterally expelled, the room air is moved such that it is transported towards the bottom side and thus to the sensor of the air delivery unit. This air is not contaminated by the incoming air and the three different air delivery units to also not significantly influence each other. List of designations
