Definitions
- the invention relates to a method for air conditioning by means of an air-conditioning ceiling made of acoustic panels spaced apart from the room ceiling and made of an air-permeable material which is provided with a porous cover.
- a flat cooling and heating element is known from patent application EP 0 756 138 A2, which is used to form an air conditioning ceiling, a partial flow of the supply air being generated above the air conditioning ceiling and passing through the porous acoustic panels of the air conditioning ceiling into the room below. Another partial flow is drawn in from the outside air and blown directly into the room through a room wall. It is therefore not necessary to hermetically seal the cavity above the air conditioning ceiling from the room below, especially since the partial flow through the air conditioning ceiling can also be supplemented by a further partial flow, which can be achieved through a larger opening in the air conditioning ceiling without any significant pressure drop into the room reached.
- the temperament tion of the room takes place essentially by convection and requires a considerable amount of tax.
- a closed suspended ceiling suspended in a room which divides a cavity located on the ceiling, via which the supply air is supplied through the suspended ceiling, while the exhaust air from the room through outlets in the Is sucked off.
- Temperature control of the room is not provided here, however, and the false ceiling does not consist of acoustic and noise-absorbing acoustic panels, so that retrofitting with a heat exchanger cannot lead to satisfactory room temperature control and sound insulation.
- the invention has therefore set itself the task of designing a method for air conditioning by means of a climate ceiling so that it can be done with little effort for the control and regulation and still creates a pleasant, draft-free indoor climate and thereby the advantages of a sound and heat insulation Execution retained.
- the object is achieved in that the acoustic panels are arranged in such a way that a cavity is formed between the air-conditioning ceiling and the room ceiling, which is flow-connected to the room through the air-conditioning ceiling and is otherwise sealed off from the room in such a way that the room has the supply air completely or at least predominantly supplied via the air-conditioning ceiling, so that the cavity is further acted upon by temperature-controlled compressed air and the pressure of which is selected such that a laminar air flow through the acoustic panels towards the room without any air flowing into the room.
- the acoustic panel and its cover are chosen so that part of the heat transport via the acoustic panel into the room takes place as heat radiation and that finally the exhaust air from a spaced from the climate ceiling and / or against that of this outgoing heat radiation is removed from the enclosed area.
- the pressure of the compressed air and the acoustic panels are chosen so that a pressure difference of at most 20 Pa occurs between the cavity and the room. This ensures that, on the one hand, a sufficient number of air changes is achieved without, on the other hand, drafts, whereby turbulence can be avoided directly on the air conditioning ceiling if the laminar air flow from the air at a maximum of 0.1 m / s ceiling emerges. In the room itself, the air flow should not exceed 0.25 m / s.
- a climate ceiling meets high requirements for comfort and health in the air-conditioned room with low demands on the construction effort and the maintenance of the system, which contributes particularly to the fact that the cavity is free of internals and there is no fear that the air supply will not drop below the dew point.
- the method creates an arrangement in which the tasks of a climate ceiling and an air system are performed simultaneously, so that the manufacture and installation can also be carried out extremely economically.
- the invention is explained below with reference to the drawing using an exemplary embodiment.
- the single figure shows a schematic section through a room with an air conditioning system operating according to the method of the invention.
- a climate ceiling 3 is suspended at a distance from its room ceiling 2 in a suitable, conventional manner, which is not indicated here.
- the air-conditioning ceiling 3 consists of individual, porous acoustic panels 4, which lie against one another and on the surrounding room walls 6 with narrow and sealed butt joints 5. At least on their sides facing the room 1, the acoustic panels 4 are each covered with a cover 7, which is also porous, so that sound waves penetrate into the acoustic panels 4 and can be absorbed here. Accordingly, a cavity 8 is formed between the air conditioning ceiling 3 and the ceiling 2 and is relatively hermetically partitioned from the space 1.
- At least one passage 13 for the exhaust air 14 can also be provided in a special arrangement described below.
- the cavity 8 is connected via at least one passage 15 to a compressed air source, which ensures the provision of the required supply air 16, which is flushed into the room 1 through the acoustic panels 4 and their cover 7 as a homogeneous laminar air flow 17.
- the pressure difference across the climatic ceiling 3 - maximum 20 Pa - is selected so that the air flow 17 exits the covers 7 at a maximum of 0.1 m / s.
- the heat flow associated with the air flow 17 remains only partially coupled to the air flow 17. Because of the special design of the acoustic panels 4 and their covers 7, each made of a material with high thermal conductivity, part of the heat flow is separated from the air flow and partly via the acoustic panels 4 and their covers 7 by heat transfer, but mostly by (inertia) heat radiation to the Delivered room 1, which can be quickly tempered in this way.
- the passage 13 for the exhaust air 14 is therefore located far away from the air conditioning ceiling 3; optionally, the area 10 containing the passage 13 is shielded from the thermal radiation emerging from the air conditioning ceiling 3.
