Abstract

Air-conditioning device for ceiling or wall mounting, which is at least for the most part recessed, with a housing (21) having a base part (22) and having at least one exhaust opening (42) and at least one separate intake opening, wherein an exhaust opening (42) and an intake opening (40, 41) together in a relation to the installed state of the device (20) substantially parallel to the ceiling (76) or wall extending bottom wall (37) of the bottom part (22) to be arranged.

Description

  • The invention relates to air conditioning devices for at least largely recessed ceiling or wall mounting according to the preambles of claims 1, 5, 8 and 17 respectively.
  • Air conditioning devices of the type mentioned are usually used in false ceilings of rooms of buildings. Also conceivable is the installation in hollow walls. In this case, necessary supply or discharge lines or power supply lines are usually also invisible laid in the ceiling or wall.
  • In the context of this application, the term "air-conditioning device" is understood to mean a device with which air can at least be heated and / or cooled. Of course, the air conditioning device may have other functions depending on demand, such as the humidification or dehumidification of the air.
  • Known air conditioning devices that can be installed in false ceilings are often aesthetically in need of improvement and build comparatively high. Furthermore, these devices disadvantageously have a very different structure, depending on whether they are primarily designed for recirculation mode (or possibly mixed air mode) or for pure outdoor air operation. In particular, when in the same room both a suitable for pure outdoor air operation device as well as a designed for primarily recirculation mode Device is to be installed, is often perceived as disturbing that their designs (usually due to the design) differ significantly.
  • On this basis, it is the object of the invention to provide an air conditioning device for at least largely submerged ceiling or wall mounting, which has a small footprint with the best possible cooling and / or heating and has an aesthetically pleasing as possible design. Preferably, the air conditioning device should work both in recirculation mode, possibly in mixed air mode, as well as in outdoor air mode or at least be converted in a simple manner accordingly.
  • An air conditioning device for achieving the stated object has the features of claim 1.
  • Accordingly, both the (at least) one blow-off opening and (at least) one separate suction opening are arranged in the bottom wall of a bottom part of the device housing extending essentially parallel to the ceiling or wall relative to the installed state of the device. For example, in an installation of the device in a horizontal false ceiling of a room to be air-conditioned of a building, therefore, both the suction and the exhaust port would be advantageously directed vertically downwards.
  • According to the invention, ambient air can be sucked in through the intake opening and be suitably treated or air-conditioned within the device, for example, before being passed out through the discharge opening to the outside. As a result, it would be possible, inter alia, to engage the device so deeply in the ceiling / wall that the bottom wall of the bottom part may even run flush with the ceiling / wall.
  • In general, however, the device also has lateral exhaust openings. The device must then naturally protrude far enough from the ceiling / wall, so that these lateral openings are exposed.
  • As far as the bottom part is concerned, it is preferably designed as a separate component. It is usually releasably connected to one or more lateral walls of the housing and closes the housing downwards from.
  • According to a preferred embodiment of the device according to the invention, the suction opening of the bottom wall in plan is arranged at least approximately centrally in the bottom wall of the bottom part.
  • Conveniently, the one or more typically a plurality of exhaust openings in an outer (edge) region of the bottom wall of the bottom part are positioned around the central Ansauföffnung around. In this case, the blow-out opening (s) is / are preferably arranged at a distance from the central blow-off opening.
  • If the bottom wall has a plurality of exhaust openings according to the rule, these are therefore expediently distributed at a distance from each other over the bottom wall. In particular, they can have contours that are essentially the same in plan view, resulting in an aesthetically clear and calm overall appearance of the bottom wall.
  • Preferably, in addition to the central suction opening in the outer region of the bottom wall of the bottom part running parallel to the ceiling / wall, a further, separate suction opening is arranged. This further intake serves - as well as the central intake - to suck in ambient air or mixed air operation of the device room air and thus contributes to a particularly high intake capacity of the air conditioning device. The contour of the additional intake opening preferably corresponds to the contour or contours of the exhaust opening (s).
  • According to an advantageous embodiment of the invention, the bottom wall of the bottom part has an at least approximately rectangular, preferably at least approximately square ground plan. In particular, a square floor plan allows the most inconspicuous installation of the device according to the invention in a so-called grid ceiling or suspended ceiling.
  • Preferably, each of the exhaust openings of the bottom wall of the bottom part is assigned in each case one side of the contour of the preferably rectangular or square bottom wall. The assignment takes place in such a way that the longitudinal sides of the contour of the respective outlet opening run parallel and at a distance from the respective, associated contour side of the bottom wall.
  • Preferably, a space associated with the ceiling / wall is heated by the blow-out opening (s) arranged in the bottom wall of the floor part to heat it be supplied. Alternatively, however, it is also conceivable, at least in principle, to supply cold air to the room through this blow-out opening (s).
  • Conveniently, (at least) a heat exchanger is provided within the housing of the device. This can be designed, for example, as an air-water heat exchanger and be operable in the pump hot water heating operation and / or in the pump cold water cooling operation and / or with a refrigerant. By means of such a heat exchanger, it is possible to use the air conditioning device according to the invention as needed as a cooling and / or heating device.
  • Another independent embodiment of the invention comprises the features of claim 5. Accordingly, in the bottom wall of the bottom part (at least) a blow-out and / or a suction disposed and additionally (at least) an exhaust opening in (at least) one, substantially perpendicular to the bottom wall or perpendicular to the ceiling / wall extending side wall of the bottom part. The arrangement of the side exhaust opening in a vertical side wall of the bottom part allows a particularly compact design of the bottom part and thus the air conditioning device. Conditioned air can be directed into the room in a confined space both through the outlet opening arranged in the bottom wall and through the outlet opening arranged in the side wall. It is thus possible, both substantially perpendicular to the wall or ceiling and in parallel to introduce conditioned air into the room. As a rule, cool air is directed into the room through the side wall, while hot air is directed through the bottom wall.
  • Conveniently, several or all, preferably at least three, side walls of the bottom part each have at least one corresponding exhaust opening.
  • According to a further preferred embodiment of the invention, the outlet opening arranged in the side wall of the bottom part has a contour which is substantially rectangular in plan. Such a blowout port adapts to the appearance of the air conditioning device as best as possible. This is especially true for the rule that the side wall itself also has a rectangular contour.
  • In a further embodiment of the invention, the exhaust opening in the side wall is arranged such that the longitudinal sides of the contour of the exhaust opening parallel in plan extend to the longitudinal sides of the preferably substantially rectangular contour of the side wall.
  • Furthermore, the bottom part can be designed such that one or more edge regions of the bottom wall protrude laterally in the plan view relative to the respective side wall. These laterally protruding edge areas at least partially obscure the exhaust openings in the side wall, so that they are not or hardly recognizable to a viewer who is in the room to be air-conditioned. Furthermore, the projecting edge regions can still have a certain guiding function for the air emerging from the outlet opening of the side wall.
  • According to a further preferred embodiment of the invention is associated with substantially rectangular, in particular square outline of the bottom wall of the bottom part of each contour side of the bottom wall one of the above, at least approximately perpendicular to the ceiling / wall or the bottom wall extending side walls.
  • At least three of these side walls preferably have their own exhaust opening. This ensures that the conditioned air is directed parallel to the ceiling / wall in at least three different spatial directions.
  • Another independent embodiment of the invention has the features of claim 8. This embodiment is characterized by an adjustable between different positions organ for adjusting the air flow, with which a stream of air flowing from the exhaust port can be changed. The adaptation of the air flow can be carried out in particular with regard to the intensity of the exiting air flow and / or with respect to its direction.
  • Advantageously, at least two separate exhaust openings are assigned to a single adjustment member. Thus, by the adjusting element at the same time the air currents of both its associated blow-off openings can be changed.
  • Particularly preferably, the adjusting member closes the first exhaust opening in a first position and releases the second exhaust opening. In a second position, there is the first exhaust port free and closes the second exhaust port. It is also conceivable that the adjusting member in at least one position both (only) partly exhaust openings closes and / or divides a flowing in the direction of the exhaust air stream on the two exhaust ports.
  • Advantageously, the adjustable adjusting member is movable by means of a motor-driven actuating means in the different positions. For example, an electrically operated servo motor can drive a suitable actuating means which moves the adjusting member. However, it is also conceivable to adjust the adjusting member, in particular by means of the adjusting means, manually between the different positions.
  • According to a further preferred embodiment of the invention, the adjusting member is at the same time associated with an exhaust opening, which is arranged in the bottom wall of the bottom part, and a discharge opening arranged in one of the side walls of the bottom part.
  • If the device is to be used, for example, for heating a room, and warm air is circulated or transported accordingly inside the device, the adjusting device can forward this hot air to the outlet opening arranged in the bottom wall. If the same device is to be used at a different time for cooling the room and accordingly cold air is transported in the device, the adjusting member can forward this cold air, for example, arranged in the side wall exhaust port.
  • Particularly preferably, the adjusting element is fastened to the bottom part in the interior of the device. Advantageously, the adjusting element is thus not or only slightly visible from the outside.
  • This applies all the more if, according to a further embodiment of the invention, the blow-out opening (s) are covered or covered by an air-permeable ventilation grille. The adjusting member and / or other components of the device are then arranged almost invisibly behind the respective ventilation grille. Appropriately, the intake openings in the bottom wall with such a ventilation grille are over or covered.
  • As regards the adjusting member, this preferably comprises a pivotable, air-impermeable flap. This flap is preferably convertible into a position in which it at least one exhaust opening in the air flow direction at least partially, especially over the entire area covered. Such a flap is a particularly effective and reliable fitting member.
  • According to a particularly preferred embodiment of the invention, the housing of the device has an opening for the supply of outside air. As a result, the device fresh fresh air can be supplied, which can treat or air-conditioning and then initiates into the room.
  • Furthermore, the device may have a metering device for metering the amount of air that can be conducted into the housing through the outside air opening. The metering device can be, for example, a mixing air flap which can be adjusted at least between two positions and with which the proportion of outside air which can be conducted into the housing can be adjusted on the air to be treated or conditioned in the device as a whole.
  • According to a further preferred embodiment of the invention, the metering member closes in a first position, the opening for supplying fresh air at least for the most part, preferably completely. In this position, the device can work in pure recirculation mode, since the supply of outside air is prevented.
  • It can further be provided that, in a second position, the metering element at least partially or for the most part, preferably completely releases the opening for the supply of outside air, so that outside air can penetrate into the interior of the device.
  • In this case, the metering device can also be designed in such a way that at the same time it interrupts one or more air passages or air passages between the intake port or ports and a suitable negative pressure source, via / via the air circulated through the intake port (s) into the interior of the device Device is sucked. In other words, the metering member in this embodiment serves inter alia to switch the device between a pure outside air operation and a pure recirculation mode.
  • In a further embodiment of the invention, however, can also be provided that the metering member can take intermediate positions in a mixed air operation in which the one or more airways or air ducts and the outside air opening are each partially closed, so that at the same time a certain proportion of room air and a certain proportion of outside air the device will be conducted.
  • The metering device can - similar to the above-mentioned adjusting member - be manually adjustable between the different positions. Preferably, however, it is also moved by means of a motor-driven actuating means in the different positions.
  • As far as the source of negative pressure is concerned, it is generally designed as a suitable fan or comprises such a fan.
  • Another independent embodiment of the invention has the features of claim 17. Thereafter, the bottom part and / or at least one further component of the device is pivotally mounted in the housing, wherein the bottom part and / or the at least one further component for maintenance or repair thereof can be pivoted from an operating position to a maintenance or repair position.
  • Due to the pivotability of the bottom part, the device can be particularly easily opened in the ceiling / wall state for maintenance or repair purposes and thus made accessible from the outside. For this purpose, the bottom part is preferably pivoted from the operating position, in which the bottom part closes the housing of the device down to a pivot axis extending in particular parallel to the bottom wall of the bottom part down into a maintenance or repair position. In this maintenance or repair position results in an opening or a sufficiently large gap between the bottom part and the housing part adjacent to the bottom part.
  • In addition or as an alternative to the bottom part, further components may be pivotally mounted. This applies in particular - if present - for a fan arranged in the device. Especially fans are particularly maintenance-intensive, so that it is particularly useful for fans to make them accessible in a simple manner.
  • According to a further embodiment of the invention, the device relative to the installed on the ceiling / wall state, especially above the bottom part of investment means that can be applied for installation of the device in particular space facing edge portions of a cutout in the ceiling / wall. Preferably, these are one or more abutment edges or abutment projections, each with one or more bearing areas extending parallel to the ceiling / wall.
  • When the device is installed in the ceiling or wall, it can be applied correspondingly with the attachment means to the space-facing edge area surfaces of the cutout. As a result, the assembly of the air conditioning device according to the invention is particularly easy to carry out.
  • Further features of the invention will become apparent from the appended subclaims, from the following description of a preferred embodiment and from the accompanying drawings. Show:

  • In the figures, an air conditioning device 20 according to the invention is shown. The air-conditioning device 20 has a housing 21 with a bottom part 22 terminating at the bottom thereof, as well as this upwardly, in particular airtight, closing lid 79.
  • The air conditioning device 20 is designed such that it is largely sunk into a cutout of a false ceiling 76 (FIG. Fig. 6 - 10 ) or alternatively a cavity wall of a room, a building or the like can be mounted.
  • For the corresponding installation of the air conditioning device 20 on or in the false ceiling 76, the air conditioning device 20 has adapted to the cutout of the false ceiling 76, relative to the housing 21 in the direction parallel to the false ceiling 76 laterally projecting attachment means. In the present example, these abutment means are a plurality of abutment angles 23 arranged respectively on upright side walls 24a, 24b, 24c, 24d of the housing 21. The abutment angles 23 each have upper abutment surfaces 23a extending horizontally or parallel to the intermediate abutment 76. The contact surfaces 23a of the contact angle 23 form a total of at least partially circumferential abutment edge.
  • To mount the air conditioning device 20 to the false ceiling 76, the air conditioning device 20 is lifted from below into the cutout in the false ceiling 76 until the contact surfaces 23 a from below on the space-facing bottom 77 of the false ceiling 76 abut or rest there. More precisely, the abutment surfaces 23a bear against edge regions of the lower side 77 of the intermediate ceiling 76 adjoining the cutout. In this position, the contact angle 23 - and with this the air conditioning device 20 - by means of suitable fastening means, such as screws or the like, attached to the false ceiling 76.
  • The housing 21 of the air conditioning device 20 is square in plan. Accordingly, the housing 21 has exactly four upright side walls 24a-d. These are rectangular in side view and in section and have substantially identical dimensions.
  • In the installed state in the false ceiling 76 of the air conditioning device 20, the majority of the same is recessed in the false ceiling 76 or in a cavity above the false ceiling 76 between the false ceiling 76 and a solid ceiling, not shown. From the room to be air conditioned, in which the false ceiling 76 is installed, therefore, the majority of the components of the air conditioning device 20 is not visible.
  • In the present embodiment, mainly the bottom part 22 extends outside or below the false ceiling 76 or protrudes downwardly therefrom. Alternatively, however, it is also conceivable to completely sink the bottom part into the false ceiling 76, in particular such that the bottom part 22 is flush with the false ceiling 76. Naturally, it is also within the scope of the invention to install the air-conditioning device 20 in such a way that larger areas thereof project downwards or are arranged visibly below the intermediate ceiling 76.
  • In a first side wall 24a of the upright side walls 24a-d of the housing 21, a side view substantially rectangular opening 25 is arranged. Through the opening 25 of the air conditioning device 20 can be supplied from the outside air. The opening 25 is arranged in the cavity above the intermediate ceiling 76, so that a non-illustrated, connectable to the opening 25 and suitable for supplying fresh air outside air duct - hidden from view - can be passed through the cavity of the false ceiling 76. To connect such an outside air line, the opening 25 has a suitable connecting piece 26.
  • On the outer side 27 of a further side wall 24b of the housing 21, auxiliary units which are useful for the operation of the air-conditioning device 20 are arranged:
  • For example, there is a speed control 28 for controlling the speed of a fan 29 disposed within the air conditioning device 20 attached.
  • Next there is a frost protection thermostat 30 is positioned. The construction and operation of such a frost protection thermostat is known and will therefore not be described here.
  • Further, on the side wall 24b connecting tubes 31a, 32a of a flow 31 and return 32 of the air conditioning device can be seen. The air-conditioning device 20 is suitable in the present example both for heating and for cooling a room. For this purpose, the air conditioning device 20 has three heat exchangers 68, each of which is connected via suitable media lines with the flow 31 and the return 32 of the air conditioning device 20. The operating fluid passed through the heat exchangers 68 can be, for example, water, but also so-called cooling fluid or other suitable media. The operating fluid can be supplied to the flow 31 of the air conditioning device 20 by means of a pump, not shown, and discharged later from the device 20 via the return 32 become. Depending on the application, the heat exchangers 68 or the operating fluid flowing into them serve to transfer heat to the interior of the air-conditioning device 20 or remove heat from its interior, in order to heat or cool the air to be conditioned by the device 20.
  • Below the connecting pipes 31 a, 31 b, a collecting tray 34 for accumulating condensate is additionally arranged on the side wall 24b. By means of the collecting tray 34, the condensed water can be collected and possibly discharged.
  • Finally, on the side wall 24b also an actuator 35 and a switch 36 are arranged. The switch 36 is a so-called repair switch. By means of this switch 36, the air conditioning device 20 can be switched off centrally and / or transferred to a repair state. In this repair condition, e.g. individual selected components of device 20 may be turned off, e.g. the fan 29 or one or the pump, which is used for the circulation of the operating fluid in the flow / return system.
  • Particularly important according to the invention, the bottom part 22 of the device 20:
  • It has a bottom wall 37 and four in side view rectangular, substantially perpendicular to the bottom wall 37 extending side walls 38. The bottom wall 37 extends in the assembled state of the air conditioning device 20 parallel to the false ceiling 76 and the space-facing bottom 77 of the false ceiling 76th
  • The bottom wall 37 is square in plan view or in plan. Each of the corresponding four sides of the contour of the bottom wall or each of the four bottom wall sides, each associated with a side wall 38 extending parallel thereto. Each of the side walls 38 extends at a distance from the respective associated bottom wall contour side. In plan view, the side walls 38 are therefore arranged offset inwardly in the direction of the bottom wall center with respect to the four lateral contour lines of the bottom wall 37. The bottom wall 37 thus projects beyond the side walls 38 in a circumferential region 39 laterally.
  • The bottom wall 37 of the bottom part 22 also has a plurality of separate openings:
  • A substantially centrally arranged in the bottom part 22 of suction port 40 in plan view or in bottom view square contour and a lateral suction port 41 with rectangular contour are used to aspirate room air in the interior of the air conditioning device 20. The side suction port 41 is disposed in the outer region of the bottom wall 37 , with distance to the central intake 40th
  • Both intake ports 40, 41 are arranged inside the bottom wall 37 in such a way that their respective four contour sides each run essentially parallel to the corresponding four contour sides of the bottom wall 37. More specifically, for all contour sides of the suction openings 40 and 41 that they each extend parallel to a contour side of the bottom wall 32.
  • The lateral suction opening 41 is rectangular and has a length substantially corresponding to one of the contour sides of the square suction opening 40. The width of the lateral intake opening 41 is substantially smaller than its length.
  • Furthermore, 22 three lateral exhaust openings 42 are arranged in the bottom wall 37 of the bottom part. Through this exhaust openings 42 air conditioned by the air conditioning device 20 to the outside, ie blown into the room to be air-conditioned.
  • The three exhaust openings 42 have substantially the same geometric dimensions as the lateral intake opening 41 and are also arranged at a distance from the central intake opening 41 in the outer region of the bottom wall 37.
  • The three exhaust openings 42 and the intake opening 41 are arranged distributed around the central intake opening 40 around. Each of the openings 41, 42 each associated with a contour side of the central suction opening 40 or one contour side of the bottom wall 37 by each two parallel contour sides of the openings 41, 42 parallel to their associated contour side of the central suction or the bottom wall 37th run.
  • In the present embodiment, exactly three of the side walls 38 have the exhaust openings 44. Alternatively, of course, more or fewer side walls have corresponding exhaust openings 44 have.
  • Through all the exhaust openings 42, 44 air is led out of the air conditioning device 20 conditioned air. The blow-out openings 42 arranged in the bottom wall 37 are used in particular to discharge hot air 91 heated by the air-conditioning device 20 perpendicularly to the intermediate ceiling 76 downwardly therefrom. In contrast, the blow-out openings 44 arranged in the side walls 38 are used in particular to guide cold air 90 produced by the device 20 parallel to the false ceiling 76 into the space to be air-conditioned.
  • After blowing cooled air parallel to the false ceiling 76, the air is guided by the side walls 38 superior, parallel to the false ceiling 76 extending peripheral portion 39 of the bottom wall 37 a little further in this parallel direction.
  • Both the intake ports 40, 41 and the exhaust ports 42, 44 are each closed with air-permeable grids 83, 84 and 85, respectively. The grids 83, 84, 85 are adapted to the shape of the respective opening 40, 41, 42, 44, that is, for example, the grid 83 of the contour of the central suction opening 40, the grid 84 of the contour of the lateral suction opening 41 and so on. The grids 83, 84 and 85 are substantially flush with the surface of the respective wall 37, 38, in which they are arranged. Alternatively, they can of course also be offset to this surface. All suction or exhaust openings 40, 41, 42, 44 are permeable to air through the grids, but closed from a perspective view substantially opaque.
  • As regards the attachment of the bottom part 22 to the device 20, it is pivotally mounted on one of the side walls 24a-d of the housing 21. By means of a hinge, not shown, the bottom part 22 of an operating position, inter alia, in the Fig. 1 is shown, pivotable in a maintenance position. In the operating position, the bottom part 22 closes the lower opening between the side walls 24a-d, in the maintenance position, this opening is at least partially free.
  • In the opening releasing position, the bottom part 22 remains connected to the side wall 24a-d, where it is supported by means of the hinge, so that it does not have to be completely removed for maintenance purposes. This makes maintenance of the air conditioning apparatus 20 particularly easy. By pivoting the bottom part 22 those components that require maintenance and are disposed within the housing 21, easily accessible.
  • Within the housing 21, the air conditioning device 20 has three baffles 45, with which in the housing the air-conditioned or air to be conditioned is performed. In this case, a guide plate 45 is each arranged substantially parallel spaced from each other to a respective side wall 24b-d of the housing 21. The distance of the respective guide plate 45 from the respective side wall 24b-d is slightly larger than the width of the exhaust openings 42 within the bottom wall 22nd
  • Each of the baffles 45 protrudes downwards from the space enclosed by the side walls 24a-d and has a fold 47 on its underside 46. In the operating position of the bottom part 22, this fold 47 rests on the inner side 48 of the bottom wall 37 of the bottom part 22, between the central suction opening 40 and the respective lateral blow-out opening 42. By means of an optional seal, not shown, or a sealing band (not shown) In principle, an air-tight connection between the respective baffles 45 and the bottom wall 37 of the bottom part 22 can be brought about.
  • The baffles 45, angled, in particular perpendicular to these extending end plates 52, the side walls 24b-d, the side walls 38 of the bottom portion 22 and a parallel to the bottom wall 37 extending partition 50 form in the housing 21 a U-shaped shaft 49. The shaft 49 extends from bottom to top of the inside 48 of the bottom wall 37 of the bottom part 22 to the horizontally or horizontally disposed in the housing 21 partition 50. The shaft 49 thus does not extend over the entire height of the housing 21st
  • The shaft 49 is generally arranged so that it extends in the horizontal direction at least over the area in which the exhaust openings 42 are arranged within the bottom wall 37 of the bottom part 22. In the vertical direction, it extends, starting from the bottom wall 37 of the bottom part 22, at least just beyond the outlet openings 44 in the side walls 38 of the bottom part 22. As a result, all three exhaust ports 42 and the three exhaust ports 44 are thus connected to each other via the shaft 49. At the end, the U-shaped shaft 49 is closed by means of the end plates 52 extending between the guide plates 45 and the respectively opposite side walls 24b-d of the housing 21 or the side walls 38 of the bottom part 22.
  • The three baffles 45 and the top 50, the partition laterally define a space whose free, not limited by a baffle 45 page by an additional Dividing wall 54 is limited, which runs parallel to the opposite side of this guide plate 45. At the bottom of this limited by the three baffles 45 and the partition 54 space is closed by a pivotally mounted flap 56. For this purpose, the flap 56 is mounted by means of corresponding pivot bearings, namely hinges 55 on the partition 50.
  • The baffles 45, the partition walls 50, 54, the flap 56 and a U-shaped drip tray 86 form a housing for receiving the fan 29, namely a fan housing 57th
  • The fan housing 57 has on its upper side 58, namely in the partition 50, via a particular funnel-shaped inlet 59 for the fan 29 sucked through the air. The fan 29 is attached directly to the flap 56 and can share this with one in the Fig. 2 shown operating position in a in the Fig. 3 shown maintenance position to be pivoted. In the maintenance position, the fan 29 is thus accessible in a simple manner from the underside 60 of the housing 21 forth.
  • The flap 56, the partition walls 50, 54, the end plates 52, parts of the side walls 24a, b, d and parts of the baffles 45 further define inside the housing 21 a suction chute 61, which at its one end in the funnel-shaped Inlet 59 opens. At its other end, the intake duct 61 covers the central intake opening 40 and the lateral intake opening 41 in the bottom wall 37 of the bottom part 22 in the lateral direction. The intake openings 40, 41 are connected in an air-conducting manner to the intake duct 61 and the fan 29.
  • The inlet 59 are 61 within an upper portion 81 of the intake duct 61 partially curved extending baffles 80 assigned. These baffles 80 extend substantially completely over the height of the upper portion 81 of the suction duct 61. They are arranged such that air sucked inside the suction duct 61 is conducted into the inlet 59 to the fan 29. Thus, in particular intake noise of the fan 29 are prevented by undirected air flowing.
  • In principle, room air can be sucked into the housing 21 of the air-conditioning device 20 by means of the ventilator 29 through the intake openings 40, 41 via the intake duct 61. Furthermore, by means of the fan 29 via the inside of the side wall 24 a arranged outside air opening 25, which opens into the intake duct 61, outside air be sucked. With the device 20 according to the invention, therefore, different modes are possible, namely pure recirculation mode, pure outdoor air operation and a mixed operation, in which a recirculated air component, an outside air content is supplied.
  • In order to adjust the different operating modes, the outside air opening 25 is assigned a metering device for metering the outside air portion, namely a mixed air flap 62.
  • In a first position, namely an outside air position 63, this allows the pure outside air operation of the air conditioning device 20. For this purpose, the pivotally mounted on an axis 64 mixing air flap 62 is located on the partition wall 54 that the air path between the fan 29 and the suction 40 and 41 is closed. Accordingly, no room air can be sucked in this position during operation of the fan 29.
  • By pivoting the mixing air damper, this can be transferred to a second position, namely a recirculation position 65. In this, the mixing air flap 62 closes the opening 25 in the housing 21 at least approximately completely. At the same time, the air path between the intake ports 40 and 41 and the fan 29 is at least largely released in this position. The air-conditioning device 20 is therefore usable in this state as a pure circulating air-conditioning device.
  • The mixing air damper 62 can also be positioned in various intermediate positions. In each of the intermediate positions of the mixed air damper 62 between the outside air position 63 and the circulating air position 65, the mixed air operation of the air conditioning device 20 is possible. In the mixed air mode, a mixture of room air and outside air that can be set in relation to the mixing air flap 62 is sucked in by the fan 29.
  • The mixed air flap 62 is adjustable by means of the outside of the housing 21 arranged actuator 35. The actuator 35 is preferably formed electrically, but it is also any other actuator for adjusting the mixing damper 62 conceivable.
  • As for the fan 29, this is a radial fan. It has an inlet opening 66 assigned to the inlet 59, through which the air is sucked out of the suction duct 61 into the fan 29. The air sucked into the fan 29 is subsequently - this is in each of the aforementioned modes of operation of the device 20 the case - radially blown out by a substantially cylindrical outer wall 67 of the fan 29.
  • The sucked by the fan 29 and accelerated in the radial direction air is directed in the direction of the baffles 45 to the adjacent to the fan 29 arranged heat exchangers 68.
  • The air conditioning device 20 has - as already shown above - three heat exchangers 68, each of which is associated with a heat exchanger 68 each have a baffle 45 and thus each one of three areas 82 of the U-shaped shaft 49. The heat exchangers 68 are in each case arranged in the fan housing 57, in each case on the sides of the baffles 45 facing the fan housing interior. The air to be moved by the fan 29 is suitably conditioned in the heat exchangers 68, ie heated or cooled depending on the application.
  • Subsequently, the air conditioned in this way passes through openings 69 respectively arranged in each guide plate 45 in the U-shaped shaft 49. The conditioned air is then supplied to the bottom part 22 via the shaft 49, in order finally to be able to blow out the air through the outlet openings 42 or 44 , This air movement is assisted or effected in the direction of the bottom part 22 by baffles 70 extending obliquely downwardly. The baffles 70 are arranged in the U-shaped shaft, in each case on the shaft-facing side of the respective baffle 45, namely above the respective opening 69th
  • For further steering / guidance or adjustment of the air streams or in the bottom part 22 22 adjustment organs for adapting the respective air flows are arranged on the inside 48 of the bottom part, namely in this case flaps 72nd
  • The flaps 72 are each arranged in a fold 71 between the bottom wall 37 and one side wall 38 and pivotally mounted on the bottom part 22. In each case one flap 72 is associated with one blow-off opening 42 in the bottom wall 37 as well as one blow-off opening 44 in the side wall 38 at the same time. In this case, each of the same side of the bottom part 22 and to a common shaft portion 82 of the U-shaped shaft 49 arranged exhaust openings 42 and 44 are each assigned to a common flap 72.
  • Each flap 72 is pivotally mounted about a pivot axis 75 within the bottom portion 22. The flaps 72 are guided during the pivoting movement by means of retaining plates 92, of which each flap 72 are each associated with two retaining plates 92, on arcuately extending oblong holes 93. They are frictionally, in particular friction-releasably fixable, so that the flaps 72 can be firmly positioned in any intermediate position within its pivoting range.
  • In the example shown, the flaps 72 are manually adjustable. Furthermore, however, it is conceivable that the flaps 72 are each adjustable by means of an actuator. As a result, the flaps 72 could be adjusted automatically within the framework of a suitable control method.
  • Each flap 72 has a flat main part 94 and an angled to this front part 95th
  • If the air conditioning device by means of the heat exchanger 68 produces cooled air, this cold air 90 is in a in the Fig. 9 shown cooling position 73 of the flap 72 is blown parallel to the bottom wall 37 through the exhaust openings 44 in the side walls 38. For this purpose, closes each flap 72, namely the respective flat main part 94, in this position, the associated discharge opening 42 in the bottom wall 37, at least for the most part by the main part 94, the corresponding exhaust opening 42 covers. Thus, the cooled air conducted by the fan 29 and the heat exchangers 68 is supplied to substantially the exhaust ports 44 disposed in the sidewalls 38 of the bottom portion 22. The angle obliquely upwardly extending front portion 95 of the flap 72 supports this Leitvorgang.
  • On the other hand, if the air-conditioning device 20 produces heated air by means of the heat exchangers 68, this hot air 91 will be in one in the Fig. 10 illustrated heating position 74 of the flap 72 of the corresponding, arranged in the bottom wall 37 exhaust opening 42 is supplied. For this purpose, each flap 72 completely releases its associated blow-out opening 42 in the bottom wall 37. The main part 94 of the flap 72 is pivoted together with the front part 95 thereof accordingly upwards. At the same time, each flap 72 in this heating position 74 at the same time completely closes off its outlet opening 44 assigned to it in the side wall 38. Thus, the hot air 91 is supplied in the heating position 74 by means of the flap 72 substantially the exhaust opening 42 in the bottom wall 37. This guide process is in turn supported by the angled front part 95. Thus, the hot air 91 in the heating position 74 of the flap 72 in Essentially perpendicular to the false ceiling 76 are discharged from the air conditioning device 20.
  • If the flaps 72 occupy one of the intermediate positions described above, the air flows are distributed to the respective, associated with the respective flap 72 exhaust ports.
  • As already mentioned above, the device 20 still has a U-shaped collecting trough 86, which is arranged below the three heat exchangers 68. This lies on the side of the three heat exchangers 68 associated baffles 45. The flap 56 of the fan housing 57 and a bottom plate 87 of the collecting tray 86 are flush in the closed state of the fan housing 57 and close the fan housing 57 together downwards.
  • In addition to the bottom plate 87, the drip tray 86 still has a peripheral, perpendicular to the bottom plate 87 extending shelf 88. This can drain on the heat exchangers 68 accumulating condensate in the drip tray 86 and collected there. Upon maintenance of the device 20, the sump 86 may be removed from the device 20 and emptied. Alternatively, the accumulating condensation water, in particular together with accumulating condensation water from the collecting tray 34, are derived by means of a suitable pump.
