Description
- This invention relates to a ceiling element intended for forming a part of the suspended ceiling of a space and having temperature control means for controlling the temperature of the space.
- Prior art discloses a ceiling element to be arranged on the ceiling of a room or another space, the element forming a part of the suspended ceiling of the space and being provided with temperature control means for controlling the temperature of the space via a warm air flow flowing from the ceiling element. In this known solution, the ceiling element is provided with a pipe system for supplying warm fluid, such as warm water, via the inlet of the ceiling element into the flow channel of the ceiling element. The flow channel or a heat exchanger forming a part of it is positioned in an air flow supplied via the air supply opening of the ceiling element into the space for warming the space. The cooled fluid is removed from the flow channel via an outlet opening to a separate heating apparatus for reheating.
- In connection with the above-described known ceiling element, one or more light sources are also arranged for illuminating the surroundings. To minimize electricity consumption, it would be preferable if the ceiling element could utilize light sources consuming as little electric energy as possible. Light sources consuming the least energy, such as LED (Light Emitting Diode) lamps are not, however, suitable to be used as light sources in connection with known ceiling elements because they heat too much, which means that their service life is too short.
- Previously there is also known from
JP - A - 2006 145183 claim 1, a solution where a light source is arranged into a duct which is utilized for supplying air into a room via an air supply opening. The need to arrange the light source into the duct supplying air via the air supply opening into the room space restricts the possibility of freely arranging the light source in such an optimal way that a good and even illumination can be obtained in the space below. - An object of this invention is to solve the above problem and to provide a solution which allows light sources consuming as little electric energy as possible to be used in a ceiling element. This object is achieved with a ceiling element according to
independent claim 1. The invention utilizes an air flow flowing from the inlet of the ceiling element towards the air supply opening, part of the air flow being separated to a nozzle. The nozzle generates a cooling air flow to the light source of the ceiling element. Thanks to the air flow provided for the light source by the nozzle, the thermal stress generated by the light source can be efficiently taken away from the light source along with the air flow, so that the temperature of the light source can be controlled better than before and its service life can be made longer. - Preferred embodiments of the ceiling element according to the invention become apparent from the attached dependent claims.
- In the following, the invention will be described in greater detail by way of example, referring to the attached figures, of which:
-
Figure 1 illustrates a first embodiment of the ceiling element according to the invention; -
Figure 2 illustrates a second embodiment of the ceiling element according to the invention; and -
Figure 3 illustrates a third embodiment of the ceiling element according to the invention. -
Figure 1 illustrates a first preferred embodiment of aceiling element 1. Theceiling element 1 is arranged in connection with a suspendedceiling 2 of a room or space, and it comprises anair supply opening 3 for supplying an air flow into the space located below theceiling element 1. Theceiling element 1 may be suspended on the actual ceiling of the space, for example. - In the example of
Figure 1 , the air flow is conveyed to aninlet 4 of theceiling element 1 along apipe 5. Thepipe 5 may be attached to the ventilation installation of the real estate, by means of which installation fresh air is brought to the space where theceiling element 1 resides. Thus, the air flow is generated by a fan belonging to the ventilation installation of the real estate. - The
ceiling element 1 ofFigure 1 also compriseslight sources 6. In this example, it is assumed that these sources are formed specifically by LED lamps comprising a plurality of light emitting diodes arranged close to each other and illuminating the surroundings of theceiling element 1, i.e. the space where the ceiling element resides. The electric connections of thelight sources 6 are implemented in the inside of ahousing 7 of theceiling element 1, to which abody 9 of thelight sources 6 extends. To guarantee sufficient cooling efficiency for thelight sources 6, the ceiling element comprisesnozzles 10 which generate, out of some of the air flow flowing from theinlet 4 of the ceiling element, a cooling flow to thelight sources 6. At their simplest, the nozzles may be formed of openings arranged at appropriate points to enable an air flow to the light sources. However, in the example ofFigure 1 , it is assumed that thenozzles 10 comprise a tubular portion with which a cooling flow can be accurately directed towards thebody 9 of thelight sources 6 extending to the inside of thehousing 7. - In order to transfer thermal stress generated by the light sources as efficiently as possible to the cooling flow generated by the
nozzles 10, thebody 9 of thelight sources 6 may be provided withcooling elements 12, which may be formed of adjacent cooling fins increasing the area to be cooled. However, this is not necessary in embodiments in which the air flow directed at the body provides sufficient cooling efficiency. - The cooling air flow ending up in the
housing 7 of the ceiling element from thenozzles 10 is conveyed out of thehousing 7 viaoutlet openings 11. It is assumed in the example ofFigure 1 that the air flow from theoutlet openings 11 ends up in the space where the ceiling element resides. In such a solution, the area of theoutlet openings 11 is preferably smaller than the area of thenozzles 10, whereby overpressure is generated in thehousing 7, where thebodies 9 of thelight sources 6 to be cooled are positioned. - The
ceiling element 1 comprises temperature control means which change the temperature of the air flow flowing from theinlet 4 to theair supply opening 3. In the example ofFigure 1 , the temperature control means comprise aflow channel 13 to aninlet 14 of which fluid, such as water, is supplied by means of apipe 16 and from anoutlet 15 of which fluid having flown through the flow channel is removed by means of apipe 17. Theflow channel 13 or a heat exchanger forming a part of it is arranged in the air flow flowing from theinlet 4 to the air supply opening 3 to change the temperature of this air flow. - If the
ceiling element 1 is used to cool the space where the ceiling element resides, the fluid to be supplied to theinlet 14 of theflow channel 13 is cold. Thus, in the example ofFigure 1 , the temperature control means cool the air flow before it ends up in thenozzles 10, whereby cooling of the light sources is at its most efficient. If theceiling element 1 is, by contrast, used to heat the space where the ceiling element resides, the fluid to be supplied to the inlet of theflow channel 13 is hot. Thus, in the example ofFigure 1 , the temperature control means heat the airflow before it ends up in thenozzles 10, whereby cooling of the light sources is not quite as efficient as in connection with cold fluid. In practice, however, the temperature of the air flow required for heating the room or space is sufficiently low, so that this air flow is applicable to cooling the light sources. The ceiling element according to the invention can be utilized in both cases. In other words, one single ceiling element can be provided with hot fluid to heat the space during the cold season and with cold fluid to cool the space during the warm season. - Above, it has been described in accordance with
Figure 1 that the temperature control means are arranged to heat or cool the air flow before some of it is separated to thenozzle 10. However, it is also feasible that thenozzles 10 are positioned in the flowing direction of air before the temperature control means. Thus, the temperature of the air flow ending up at thenozzles 10 is the same as the temperature of the air flow to be supplied to the inlet, and only the temperature of the air flow flowing further to theinlet opening 3 is changed. -
Figure 2 illustrates a second preferred embodiment of a ceiling element 1' according to the invention. The embodiment ofFigure 2 corresponds to a great extent to the embodiment ofFigure 1 , due to which the embodiment ofFigure 2 is described in the following primarily by bringing forth differences between the embodiments. - In the case of
Figure 2 , the ceiling element 1' also comprises afan 18 to generate an air flow from theinlet 4 to theair supply opening 3. By way of example, it is assumed in the case ofFigure 2 that the air intake opening of the fan opens to above the ceiling element 1', i.e. in practice to the space between the suspendedceiling 2 and the actual ceiling of the space or room. In accordance with the invention, the air intake may alternatively take place from the room or space itself, in which case the suspended ceiling, for example, may have an opening connected via a pipe to the air intake opening of thefan 18. In both cases, the ceiling element 1' generates a closed cycle in the room or space where it resides. In such a solution, fresh air is conveyed to the room or space in another way. - Deviating from the case of
Figure 2 , it is also feasible that also apipe 5 supplying fresh air leads to the air inlet opening of thefan 18, as in the case ofFigure 1 . In such a case, some of the air ending up in the air inlet opening of thefan 18 may be fresh air to be supplied along thepipe 5, and some may be air to be recycled, originating from the room or space (from above or below the suspended ceiling 2) where the ceiling element resides. -
Figure 3 illustrates a third preferred embodiment of the ceiling element according to the invention. The embodiment ofFigure 3 corresponds to a great extent to the embodiment ofFigure 1 , due to which the embodiment ofFigure 3 is described in the following primarily by bringing forth differences between the embodiments. - In the embodiment of
Figure 3 , thelight sources 6 are arranged on aceiling element 1" in such a way that theirbodies 9 are positioned completely or nearly completely outside thehousing 7 of theceiling element 1". Thus, nozzles 10' are arranged to project out of the housing of theceiling element 1" to control some of the air flow originating from theinlet 4 towards thelight sources 6.Openings 11 according to the preceding embodiments are thus not needed in this embodiment. - In
Figure 3 , thebody 9 of thelight source 6 is shown without the coolingelement 12 according to the preceding embodiments, although also in this embodiment the body of the light source may be provided with a cooling element increasing the area to be cooled. - In the embodiment of
Figure 3 it is assumed, by way of example, that theceiling element 1" has no fan but that the flowing air is conveyed along thepipe 5 to the inlet of theceiling element 1". Deviating from what is shown inFigure 3 , the solution described in the context ofFigure 2 may be used, whereby theceiling element 1" comprises a fan which is similar to the one inFigure 2 and whose air intake opening takes some or all of the required air from the space or room where theceiling element 1" resides. - It is to be understood that the above description and the related figures are only intended to illustrate the present invention. Different variations and modifications of the invention will be obvious to a person skilled in the art without deviation from the scope of the invention.
