Definitions
- the invention relates to a device for the air conditioning of technical rooms, in particular measuring rooms comprising a measuring room floor, measuring room walls and a measuring room ceiling by means of at least one air conditioning device, preferably arranged above the measuring room ceiling, by means of which conditioned air can be supplied to the measuring room via supply air openings, preferably arranged in the measuring room ceiling area, which after circulation in the measuring space can be removed from it again via exhaust air openings and at least partially fed back to the air conditioning device.
- a measuring room is a room or part of a room in which specified requirements for the ambient conditions, for example with regard to permissible temperatures, vibrations, humidity and the like must be fulfilled so that values of measured variables with specified measurement uncertainties can be determined.
- Such measuring rooms are used on the one hand for precise, reproducible measurements, but on the other hand also for processing, for example, precision mechanical workpieces and the like.
- VDI / VDE guidelines 2627 sheet 1 The classification and the parameters of such measuring rooms are set out in VDI / VDE guidelines 2627 sheet 1, to which reference is made in this respect.
- a measuring room 10 comprises a measuring room floor 11, measuring room walls 12 and a measuring room ceiling 13.
- supply air openings 20 are provided through which conditioned air, which is emitted by an air conditioning device not shown in FIG. 5, can be fed to the measuring space 10.
- the supply air openings 20 are essentially evenly distributed over the measuring room ceiling 13. They impart a swirl to the conditioned air flowing into the measuring space, so that the air flows from the supply air openings 20 in a spiral to the measuring space floor 11.
- the object of the invention is therefore to develop a device for air conditioning measuring rooms of the generic type in such a way that circulating conditioned air in the measuring room while maintaining a precisely adjustable measuring room temperature is possible with the simplest possible technical means, in particular with the smallest possible air conditioning devices.
- This object is achieved in a device for air conditioning measuring rooms of the type described in the introduction in that an air guiding device is arranged below the ceiling of the measuring room, through which the conditioned air released by the air conditioning device is directed in the direction of the measuring room walls and which has supply air openings directed towards the measuring room walls.
- the arrangement of air guiding devices, through which the air-conditioned device released by the air conditioning device is directed in the direction of the measuring room walls and which has supply air openings directed towards the measuring room walls, has the particularly great advantage that the air released by the air conditioning device in a laminar flow essentially along the ceiling of the measuring room the walls of the measuring room flows to the floor of the measuring room and is not only circulated there in the measuring room and the heat of the absorbs air located in the measuring room, but additionally also absorbs and dissipates the heat of the measuring room walls.
- the room is flooded using the direct current principle.
- the at least one exhaust air opening is arranged so as to be adjacent to or as part of the air guiding device in such a way that it is as far away as possible from the supply air openings and is arranged closely adjacent to the measuring room walls.
- This arrangement of the exhaust air opening enables a particularly optimal circulation of the air-conditioned air emitted by the air conditioning device in the measuring space in laminar flow.
- the design of the air guiding device can be implemented in a wide variety of ways.
- An embodiment which is particularly advantageous with regard to their manufacture and arrangement in the measuring room provides that the air guiding device comprises at least one, preferably flat, air guiding plate arranged at a distance below the measuring room ceiling, which is angled toward the air conditioning device on its side facing the air conditioning device and on its side towards the air conditioning device facing away and facing at least one wall of the measuring room ends forming the at least one supply air opening.
- Such an angled air baffle enables a laminar flow of the air-conditioned air emitted by the air-conditioning device to the walls of the measuring room in a particularly simple manner.
- Another very advantageous embodiment provides that a further air baffle is arranged between the flat air baffle and the measuring room ceiling, which is bent so that together with the flat air baffle an air duct is formed which has a cross-sectional reduction on its side facing the air conditioning device.
- a particularly optimal flow of the conditioned air leaving the air conditioning device is made possible by this air duct and in particular by the constriction arranged in it.
- the flat air baffle has a plurality of openings on its side facing the air duct. These post-flow openings advantageously achieve induction of the air from the inside of the room into the temperature-controlled volume flow output by the air conditioning device. As a result, mixing occurs and thus temperature compensation of the air flowing in through the openings and the air emitted by the air conditioning device. In this way, the air to be supplied to the measuring space is already tempered in the air guiding device.
- the air baffle is extended below the ceiling of the measuring room in such a way that its covering area is greater than or equal to the area covered by a device arranged in the measuring room, for example a measuring device or a processing machine. This results in an optimal air flow in the measuring room.
- FIG. 1 shows a bottom view of a device for air conditioning measuring rooms that makes use of the invention and is fastened below a measuring chamber cover;
- FIG. 2a shows a detailed bottom view of an exemplary embodiment of a device according to the invention for air conditioning measuring rooms
- Fig. 2b is a sectional view of the device shown in Fig. 2a;
- FIG. 3a shows a bottom view of a further exemplary embodiment of a device according to the invention for air conditioning measuring rooms
- 3b is a sectional view of the device for air conditioning measuring rooms shown in FIG. 3a; 4 schematically shows the air flow in a measuring room, which is caused by the devices for air conditioning measuring rooms shown in FIGS. 2 and 3, and
- FIG. 5 schematically shows the air flow in a measuring room of a device for air conditioning measuring rooms known from the prior art.
- a measuring room 10 shown schematically in FIG. 4 comprises a measuring room floor 11, measuring room walls 12 and a measuring room ceiling 13.
- An air conditioning device 30 is attached above the measuring room ceiling 13 in a manner known per se, through which conditioned air can be supplied to the measuring room 10, which air is circulated in the measuring room 10 and thus brings about temperature compensation.
- an air-guiding device in the form of an air-guiding panel 50 is provided below the air-conditioning device 30, which is angled adjacent to an exhaust air opening 60 arranged essentially centrally in the air-conditioning device 30 and on its side facing away from the exhaust air opening 60 with the formation of supply air openings 52 , which are formed between the air baffle 50 and the measuring chamber cover 13 and face the measuring chamber walls 12, ends.
- the air-conditioned air emitted by the air-conditioning device 30 is directed in laminar flow through this air-guiding panel 50 to the measuring-room walls 12, where it flows downward and is deflected in the area of the measuring-room floor 11, and then again through the exhaust air opening 60 into the air-conditioning device 30 stream, in which it is reprocessed, for example cooled, dusted and cleaned, before it is again supplied to the measuring chamber 10 via the air guide panel 50.
- the air flowing past the walls of the measuring room in a laminar flow absorbs heat from the measuring room and in particular also from the walls of the measuring room and supplies it to the air conditioning device 30. This is the best way to achieve a precisely adjustable measuring room temperature.
- FIG. 2a A first embodiment of a device for air conditioning measuring rooms is shown in detail in Fig. 2a, b.
- the air guide panel 50 is fastened to the ceiling support elements 70 by spacing elements 51, to which the air conditioning device 30 is also fastened.
- the air-conditioning device 30 has a central exhaust air opening 60 and, at its lower ends facing the measuring space 10, air outlet openings 31 through which conditioned air can flow into the air guide duct formed by the air guide panel 50.
- the embodiment shown in Fig. 3a, b differs from that shown in Fig. 2 in that between the substantially planar air baffle 50 and the measuring room ceiling 13, a further air baffle 80 is arranged, which is angled twice so that together with the flat air guide panel 50 results in an air duct 87, which on its side facing the air conditioning device 30 has a cross-sectional reduction 83, which leads to a flow of the conditioned air emerging from the air conditioning device 30 at a higher speed. Following this taper 83, the air duct 87 opens to the supply air openings 52 are formed between the flat air baffle 50 and the measuring room ceiling 13, funnel-shaped.
- the flat air guide panel 50 has openings 57 which optimize the flow of the conditioned air in the air duct 87 in that air flowing through it is mixed with the air flowing in the air duct 87. This results in a temperature compensation of the air flowing in the air duct 87. In this way, the inflow through the openings 57 already enables a termination, mostly a heating of the air flowing in the air duct 87.
- the conditioned air flows along the measuring room walls 12 towards the measuring room floor 11, is deflected there and fed through the exhaust air opening 60 to the air conditioning device 30, in which the air circulated in this way is conditioned, dedusted or processed in a similar manner .
- the air guide panel 50 of the device for air conditioning measuring rooms has the shape of a surface surrounding the air conditioning device 30, in which the exhaust air opening 60 is arranged. This makes it possible in a simple manner that the supply air openings 52 are arranged as far as possible from the exhaust air opening 60, as a result of which the circulation of the air in the measuring space advantageously proceeds.
- the air baffle 50 arranged below the measuring room ceiling 13 is expanded in such a way that its covering area is greater than or equal to the area that one arranged in the measuring room 10 Measuring device, processing machine or the like. Covered.
- a heating device is arranged between the measuring space ceiling 13 and the air guide panel 50, which is preferably attached to the air guide panel 50. This heating device makes it possible to heat the air supplied to the measuring space via the air baffle 50.
