Definitions

  • the invention relates to a measuring room containing a Device for air conditioning measuring rooms comprising a measuring room floor, measuring room walls and one Measuring room ceiling, at least one, preferably over air-conditioning system arranged on the ceiling of the measuring room is provided, through which the measuring room over preferably arranged in the ceiling area Air-conditioned air can be supplied to supply air openings, which after circulation in the measuring room from this over Exhaust openings can be removed again and at least is partially re-feedable to the air conditioner.
  • a measuring room is a room or part of an area Space in which specified requirements for the Environmental conditions, e.g. regarding permissible Temperatures, vibrations, humidity and the like must be satisfied so that values of measured variables with given measurement uncertainties can be determined can.
  • Such measuring rooms serve on the one hand more precisely, reproducible measurements, but also the Processing, for example, of precision mechanics Workpieces and the like.
  • a measuring space 10 includes a Measuring room floor 11, measuring room walls 12 and a measuring room ceiling 13.
  • a measuring room ceiling 13 In the ceiling 13 there are supply air openings 20 provided by which conditioned air by an air conditioning device not shown in FIG. 5 is delivered, the measuring space 10 can be fed.
  • the Supply air openings 20 are essentially via the Measuring room ceiling 13 evenly distributed.
  • An air-conditioning device emerges from JP-A-60 078 242 which a room to cool down Supply air openings supply conditioned air.
  • This Air conditioning is, for example, under a blanket arranged. Most of the air conditioned is in the room to be cooled via supply air openings in Horizontal direction fed. A smaller part flows vertically down. Even with one Air conditioning devices can have turbulent flows conditioned air that cannot be avoided a measuring room are particularly annoying because they are too Fluctuations in the measuring room temperature to be set to lead.
  • the object of the invention is therefore to provide a device for Air conditioning of measuring rooms of the generic type to develop in such a way that circulation is conditioned Air in the measuring room while maintaining a precise measuring room temperature to be set with if possible simple technical means, especially with air conditioning that is as small as possible is possible.
  • the arrangement of air control devices through which the conditioned air released by the air conditioner in Direction of the walls of the measuring room and which on the measuring room walls have directed supply air openings has the particularly great advantage that the Air conditioning air emitted in laminar flow from the measuring room ceiling essentially along the Measuring room walls flow to the measuring room floor and not only there is circulated in the measuring room and thereby the heat of the the air located in the measuring room, but additionally also absorbs the heat of the measuring room walls and leads away.
  • the room is flooded in the direct current principle.
  • the at least one exhaust opening so adjacent to or as part of the air guiding device is arranged so that it from the supply air openings as far away as possible and the walls of the measuring room is arranged closely adjacent.
  • This arrangement of Exhaust air opening allows a particularly optimal Circulation of the air conditioning conditioned air in the measuring room in laminar Flow.
  • the design of the air guiding device can in principle only in a variety of ways be realized.
  • One particularly with regard to their Manufacturing and arrangement in the measuring room especially advantageous embodiment provides that the Air guiding device at least one at a distance preferably arranged below the ceiling of the measuring room includes flat air baffle, which on its the Air conditioning device side facing the air conditioning device is angled and on the air conditioning facing away and facing at least one measuring room wall Side under formation of at least one Supply air opening ends.
  • angled Air baffle is a particularly simple laminar flow of air conditioning released conditioned air to the measuring room walls allows.
  • Another very advantageous embodiment provides that between the flat air baffle and the measuring room ceiling another air baffle is arranged, which is bent so that together with the flat air baffle an air duct is created on its the air conditioning side facing one Cross-section reduction. Through this Air duct and especially through the one in it arranged narrowing becomes a particularly optimal one Flow of those leaving the air conditioner allows conditioned air.
  • the air baffle is extended below the ceiling of the measuring room in such a way that their coverage area is greater than or equal to the area is that of one arranged in the measuring room Device, for example a measuring device or a processing machine is covered. To this This results in an optimal air flow in the Measuring space.
  • a measuring space 10 shown schematically in FIG. 4 comprises a measuring room floor 11, measuring room walls 12 and one Measuring room ceiling 13.
  • an air conditioner 30 through which conditioned air can be supplied to the measuring space 10, which is circulated in the measuring space 10 and thus a temperature compensation causes.
  • an air guiding device provided in the form of an air baffle 50, which adjacent to an essentially central one in the Air-conditioning device 30 arranged exhaust air opening 60 is angled and on the exhaust air opening 60 side facing away from supply air openings 52, between the air baffle 50 and the Meßraumdeke 13 formed and facing the measuring room walls 12 are, ends.
  • the air conditioner 30 discharged conditioned air in laminar flow directed towards the measuring room walls 12, where it flows down and in the area of the Measuring room floor 11 is deflected, then through again 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 again via the air baffle 50 to the measuring space 10 is fed.
  • the laminar flow to the Air flowing past the walls of the measuring room takes out of the measuring room and especially heat from the walls of the measuring room and feeds them to the air conditioner 30. Just this makes a precise in an optimal way Measurement room temperature to be set achieved.
  • FIG. 2a, b A first embodiment of a device for Air conditioning of measuring rooms is detailed in Fig. 2a, b shown.
  • the Air baffle 50 by spacers 51 on Ceiling support elements 70 attached to which also Air conditioning device 30 is attached.
  • the air conditioner 30 has - as already mentioned above - a central one Exhaust air opening 60 on and at the measuring space 10 facing lower ends of air outlet openings 31, through which conditioned air in the through which Incoming air guide aperture 50 formed air guide channel can.
  • FIG. 3a, b differs from that shown in FIG. 2 in that in each case between the substantially flat Air baffle 50 and the ceiling 13 another Air baffle 80 is arranged, which is twice as is angled that together with the plane Air baffle 50 results in an air duct 87 which on its side facing the air conditioning device 30 has a cross-sectional reduction 83 that leads to a Flow of those emerging from the air conditioning device 30 conditioned air at a higher speed.
  • This taper 83 then opens Air duct 87 to the supply air openings 52, the between the flat air baffle 50 and the Measuring room ceiling 13 are formed, funnel-shaped.
  • this funnel-shaped area has the plane Air baffle 50 openings 57 on which the flow the conditioned air in the air duct 87 optimize by having air flowing in through them of the air flowing in the air duct 87 is mixed. This causes temperature compensation of the air flowing in the air duct 87.
  • the Inflow through the openings 57 enables them Already a term, mostly one Heating of the flowing in the air duct 87 Air.
  • the Air baffle 50 of the device for air conditioning Measuring rooms the shape of the air conditioning device 30 surrounding area in which the exhaust air opening 60 is arranged. This enables in a simple manner that the supply air openings 52 from the exhaust air opening 60 are arranged as far away as possible, whereby the circulation of the air in the measuring room advantageous runs.
  • the air baffle arranged below the measuring room ceiling 13 50 is so extensive that her Coverage area is greater than or equal to that Area which is arranged in the measuring space 10 Measuring device, processing machine or the like covered.
  • a heating device is arranged, which is preferably is attached to the air baffle 50. Through this Heating device is a heating of the measuring room the air baffle 50 allows air supplied.
