Description

The invention relates to a ceiling air conditioning device.

A known type of air conditioning devices for arrangement on and in particular in a ceiling comprises both a supply for air and for water as an additional temperature control medium. To supply air, an air duct runs in a longitudinal direction of the known arrangement. Arranged below the air duct is a profile element with ribs running in the transverse direction, which is tempered by lines for water as a temperature control medium arranged on the profile element for tempering the profile element. The air duct has a number of outlet openings arranged between the ribs, through which the air is blown out of the air duct.
An air conditioning device according to the preamble of claim 1 is from the patent document CH-A-707246 known.

It can be regarded as a task to provide a possibility for simple fastening in a ceiling air conditioning device with an air duct and profile element. The object is achieved by a ceiling air conditioning device according to claim 1. Dependent claims relate to advantageous embodiments of the invention. The ceiling air conditioning device according to the invention has at least one air duct running in a longitudinal direction for supplying air. A profile element with a number of ribs running in the transverse direction is arranged below the air duct. The profile element is preferably made of a highly thermally conductive material, in particular metal, particularly preferably aluminum.

At least one line for a temperature control medium is provided on the profile element, through which the profile element can be cooled or heated. Water is preferably used as the temperature control medium. For a good thermal coupling of the line to the profile element, the line preferably has a plurality of connected line sections, which in particular can preferably run parallel, for example in the longitudinal direction.

The air duct has a number of outlet openings arranged between the ribs of the profile element, so that air can be blown out through the outlet openings into the spaces between the ribs. The outlet openings are preferably designed in such a way that the air from the air duct flows at least essentially in the transverse direction, that is to say along the ribs. The blown-out air and, if applicable, the room air sucked in by the air flow is thus tempered by intensive contact with the profile element, i.e. usually chilled.

According to the invention, at least one support profile is provided on the ceiling air conditioning device. For coupling to the support profile, the profile element has at least one groove running in the longitudinal direction. The support profile has at least one tongue for engaging in the groove. The support profile and thus preferably both tongue and groove extends in the longitudinal direction.

The support profile thus offers a favorable possibility on the one hand for stabilizing the profile element and on the other hand for connecting the profile element to other parts of the device. But above all, the support profile can be used to suspend the entire ceiling air conditioning device.

The support profile preferably extends at least substantially over the length of the profile element, which in the present case means a length of at least 80%, preferably 90% of the length, particularly preferably the entire length. The support profile is preferably formed in one piece, particularly preferably made of metal. Preferably, the support profile has a constant cross-section, i.e. H. in particular the spring is preferably formed over its entire length.

Tongue and groove have mutually fitting shapes, so that a positive connection is formed.

While the groove could be formed at various points on the profile element, for example also on its top or bottom, it is preferably on at least one of the long sides arranged; the two opposite longitudinal sides particularly preferably each have grooves. The depression of each groove preferably extends at least substantially in the horizontal direction, so that the load can be absorbed in the vertical direction by the engagement between the groove and the tongue.

According to a preferred embodiment, the cross section of the support profile has at least a first profile section which rests on the upper side of the profile element and a second profile section which rests on a side surface of the profile element. The support profile thus preferably overlaps a longitudinal edge, particularly preferably the upper longitudinal edge of the profile element. The tongue is preferably arranged on the second profile section, which rests on the side surface where, in accordance with the preferred embodiment, the associated groove is located. The first profile section, however, can be attached to the top of the profile element in different ways. In a preferred embodiment, the first profile section is fastened on the upper side of the profile element by at least one screw, preferably by a plurality of screws spaced in the longitudinal direction.

When fastening the support profile to the profile element by screws, it is particularly preferred that the screws reach through the support profile and are anchored to the top of the profile element without a passage to the underside. This can be achieved, for example, by self-tapping screws or by a previously inserted thread on the top of the profile element. A screw connection only on the top without a passage to the bottom of the profile element offers the advantage on the one hand that the attachment from the bottom, i. H. is not visible on the ceiling. On the other hand, any work on the underside, in particular between the ribs, which could possibly lead to visible scratches, bends or other damage, is also avoided during the attachment.

The profile element can have a wide variety of shapes in cross section. The top and bottom sides are preferably planar and parallel. The longitudinal side surfaces can run completely or partially perpendicular to the top. In a preferred embodiment, however, at least a portion of a side face of the profile element can form an angle of less than 90 ° with the upper side, ie, run obliquely outwards. The angle can be 45 ° or greater, for example, preferably 50 ° to 70 °.

At least one holder for the line can be arranged on the profile element, preferably on the upper side thereof. The holder can have a line detection area which at least partially encompasses, for example, a round line and a, for example, flat contact area for contacting the top of the profile element. The bracket can, at least in part, be attached to the profile element by the support profile. E.g. can be a part of the bracket, preferably the flat contact area, clamped between the support profile and the profile element and thus attached. Good attachment and installation can be achieved in a simple manner.

In a preferred embodiment, the support profile can have a rail area in which a suspension element or a connecting element can be received in a form-fitting manner. Such a rail area preferably has an undercut on opposite longitudinal sides, so that an element which is positively received therein is encompassed on opposite sides. The rail area and the matching suspension element or connecting element are thus preferably shaped in such a way that at least a part, for example a foot, can be pushed into the rail area in the longitudinal direction. The suspension element can be used in particular for hanging the profile element or the entire ceiling air conditioning device in the ceiling area. For this purpose, the suspension element can have an at least substantially vertically arranged threaded rod, with which a suspension can be achieved at an adjustable height. For example, four suspension elements can be provided for a ceiling air conditioning device.

Two support profiles can particularly preferably be provided in parallel at a distance from one another. It is possible to connect the support profiles to a frame by at least one cross strut, preferably by at least two cross struts arranged at a distance from one another. With such a frame, a particularly high stability of the entire ceiling air conditioning device can be achieved.

The profile element can be formed in one piece or at least in one piece. It can preferably be composed of a plurality of partial profile elements, each of the partial profile elements preferably being formed in one piece with a plurality of ribs.

Several partial profile elements can, for example, be provided next to one another in the longitudinal direction. A connection of the partial profile elements can be achieved in particular by the support profile.

An embodiment of a ceiling air conditioning device 10 is shown in FIG Fig. 1, Fig.2 shown in perspective. How especially out Fig. 2 can be seen, a plurality of parallel ribs 12 are arranged on the underside. On the top are like in Fig. 1 an air duct 14 and line sections 16 of a cooling line are shown. The air duct 14 extends in a longitudinal direction L, while the ribs 12 run at right angles in a transverse direction Q.

The structure of the ceiling air conditioning device 10 is particularly from the cut perspective views 3a, 3b as well as from the exploded view Fig. 4 evident. The ribs 12 are formed on a profile element 20. The profile element 20 is composed of a plurality of partial profile elements 22, one of which is shown in FIG Fig. 6 is shown. The partial profile elements 22 are placed close together in the longitudinal direction L in order to form the profile element 20.

Each of the partial profile elements 22 is formed as a one-piece, solid element made of metal, for example aluminum, and can be produced in particular by the extrusion process. It points like in Fig. 6 shown a base plate 24 with a flat, closed top 24 from which the ribs 12 extend. An opening 26 in the base plate 24 runs centrally in the longitudinal direction L.

A distribution plate 28 is arranged in the opening 26 and has a row of outlet openings 30 on both sides in the longitudinal direction L. The distribution plate 28 forms the underside of the air duct 14.

The outlet openings 30 are each arranged between the ribs 12, so that air supplied from the air duct 14 is discharged through the outlet openings 30 in the spaces between the ribs 12. The outlet openings 30 are arranged such that the air flows essentially horizontally into the spaces between the ribs 12. As a result, ambient air is drawn in and there is an intensive heat transfer between the air flow and the ribs 12 of the profile element 20.

The profile element 20 is cooled by the cooling line 16. The cooling line 16 runs in parallel line sections in the longitudinal direction L meandering on the top 24 of the profile element 20. Fixing profiles 34 are provided for this ( 7a, 7b ) with a holding area 36 which partially encompasses the line 16 and a support surface 38 for support on the upper side 24 of the profile element 20 ( 9, 10 ).

The ceiling air conditioning device 10 comprises a support frame 42 ( Fig. 4 ) with two support profiles 40 which extend over the entire length of the ceiling air conditioning device 10 and which are connected at the end to cross struts 44. The support frame 42 and in particular the support profiles 40 serve on the one hand to connect the individual partial profile elements 22 to the overall profile element 20 and on the other hand to connect the ceiling air conditioning device 10 to other parts, in particular for suspending the ceiling air conditioning device.

Sections of the support profiles 40 are in 8a, 8b shown, where Fig. 8b shows the cross section. In cross section, each of the support profiles 40 has a first profile section 46a and a second profile section 46b, which are arranged at an angle of approximately 60 ° to one another.

How especially out 9, 10 , Fig. 12 it can be seen, the support profiles 40 are provided for arrangement along the upper longitudinal edges 52 on both sides of the profile element 20. The first profile section 46a rests on the upper side 24 of the profile element 20, while the second profile section 46b rests on a side surface 54 that is bevelled against it.

In order to enable a load-bearing connection between the support profile 40 and the profile element 20, the profile element 20 has in its side surface 54 a groove 50, the depression of which extends in the horizontal direction starting from the side surface 54. In the example shown, the groove 50 is arranged on the side surface 54 of the profile element 20 in the region of the ribs 12, just below the base plate 24 forming the upper side.

In particular, it engages in the groove 50 9, 10 , Fig. 12 a spring 60 of the support profile 40 can be seen. The tongue 60 is received in the groove 50 such that there is a contact surface over the entire length L on the top of the groove 50 and tongue 60. Thus, the support profile 40 can the weight of the solid profile element 20 well take up.

The spring 60 is as in Fig. 8b shown formed on the inside of the second profile section 46b. The second profile section 46b also has on its opposite outer side a rail area 56 with hold-down devices 58a, 58b arranged opposite on both sides. A notch 62 is provided on the outside of the first profile section 46a.

The notch 62 is used to simply fix the support profile 40 to the profile element 20 by means of self-tapping screws 62 ( 9, 10 ). When assembled, the notch 62 is used for easy positioning of the screws 64 which are screwed through the first profile section 46a into the base plate 24 of the profile element 20. The screws 64 are anchored in the base plate 24 of the profile element 20 and do not penetrate them, ie do not protrude into the region of the ribs 12.

Thus, the attachment of the support profile 40 to the profile element 20 takes place without the need to work in the space between the ribs 12; in addition, the attachment is not visible from the bottom.

The support profile 40 also serves to fasten the holding plates 34 for the line sections 16 on the top of the profile element 20. For this purpose, a recess 64 is provided on the inside of the first profile section 46a of the support profile 20. How from Fig. 10 it can be seen, the first profile section 46a covers the edge of the holding plate 34 running next to it at this point and thus fixes this on the upper side of the profile element 20.

The rail area 56 on the outside of the second profile area 46b serves for the positive reception of connecting elements 66 ( 9, 10 ) and / or suspension elements 70 ( 11, 12 ).

The connecting elements 66 serve as in FIG Fig. 10 shown for connecting the support profiles 40 to the cross struts 44. A foot region 68 of the connecting elements 66 is received in a form-fitting manner in the rail region 56 and additionally fixed by screws.

Additionally or alternatively, suspension elements 70 can be fastened to the rail area 56, in which case, as in FIG Fig. 12 each shown, a foot area 74 is positively received in the rail area 56.

The suspension elements 70 are used to suspend the ceiling air conditioning device 10. In the example shown, they are designed as angled sheets, an upper angled region 76 having a bore for receiving a threaded rod 72.

In this way, a single ceiling air conditioning device 10 as well as a composite of several ceiling air conditioning devices can be securely suspended. For this purpose, the required number of suspension elements 70 is inserted into the rail area 56 of the support profiles 40. It has been found that four suspension points are sufficient for each ceiling air conditioning device 10.

As in Fig. 11 A plurality of ceiling air conditioning devices 10a, 10b can also be arranged one behind the other in the longitudinal direction. The support profiles 40 can run continuously or can be connected to one another at the ends.
