Definitions
- the invention relates to a laboratory containing an arrangement of work tables and a ventilation arrangement arranged above the work tables according to the preamble of claim 1.
- ceiling constructions are used for setting up research laboratories, e.g be attached directly to the associated building ceiling with the help of suitable fastening devices using dowels. Since the lines are usually laid one after the other by different personnel, the difficulty arises that the lines sometimes not only run criss-cross and alternately in several levels, but also because of the individual installation of the fastening devices later spatial changes to an existing laboratory arrangement can only be made with great effort.
- a ceiling construction for a laboratory room is known from EP 1 934 414 B1, in which the gaseous and liquid media as well as electricity are routed in an orderly manner in main supply lines running parallel to one another in the area of the laboratory ceiling, which are accommodated on a support frame made of profile supports.
- the various media are routed from the main supply lines via flexible branch lines, which can be connected to the supply lines using quick-release couplings, to the respective hanging media columns, which are mounted above the laboratory tables at the corresponding workstations on the underside of the support frame.
- An arrangement for ventilation of a laboratory is known from WO 20 12 031 700 A1, which has an aisle area which is delimited on both sides by work tables.
- the ventilation arrangement comprises a combined supply air duct-air outlet arranged above the aisle area for supplying fresh air into the room and an exhaust air duct arranged above it for removing exhaust air from the room.
- the combined supply air duct air outlet which is also generally referred to as a supply air duct, has a large number of air outlet openings from which the supply air exits laterally above the aisle area in the direction of the work tables.
- the exhaust air duct has two slot-like suction openings which extend essentially parallel to the air supply duct and are arranged in the area of the ceiling of the room.
- an air duct forms on both sides of the aisle area, via which heated supply air in the area of the work tables reaches the area of the ceiling of the room in a vertical direction, which includes a large number of flat, plate-shaped ceiling panels which form a suspended ceiling inside from which the supply lines for the media required in the laboratory are routed.
- the laboratory in which the last-mentioned ventilation arrangement is used has a significantly reduced energy requirement for the legally prescribed air exchange compared to laboratories with conventional supply and exhaust air ducts, since the supplied, cleaned and usually cooled supply air in summer does not interact directly with the heated exhaust air mixed above the tables before it is discharged through the exhaust air duct.
- a further object of the invention is to design a laboratory with an arrangement of workbenches contained therein and a ventilation arrangement arranged above the workbenches in such a way that it has a reduced energy requirement for exchanging the air ducted in the laboratory.

- the media lines are bundled straight to the rear and run down over the rear longitudinal edges 112r of the worktables 110, they no longer rest loosely as loops behind the devices on the worktops 112 of the tables. This ensures order and makes it easier to clean the table surfaces.
- the worktops 112 of the worktables 110 which are preferably along of parallel rows (not shown in detail) are arranged on both sides of the central supply air ducts 310 of the ventilation arrangements 300, comprise an upwardly directed nose or lip 113, which deflects an air flow rising from the area below a worktop 112 in the vertical direction in the manner of a spoiler, so that it can optimally rise upwards.
- this advantageously further reduces the energy requirement for providing the air exchange required in a laboratory.
- the space underneath the worktops 112 of the tables 110 is thereby also covered and flushed by this air flow.
- longitudinal grooves 4 can be formed in the lateral end faces of the elongated vertical profile 2 of the media columns 1 to accommodate the vertically running lateral edges of flat separating elements 130, which are positioned between the inherently rigid profiles 2 of two spaced apart Media columns 1 can be arranged in order to spatially separate the work areas, in particular in the case of the work tables 110 shown in FIG. 5 standing back to back, as a splash guard.
- the aforementioned longitudinal grooves 4 can also be used to accommodate fastening elements for shelves 150, not shown in detail, to which, for example, the bottoms of the shelves 150 are fastened.
- the fastening elements can be, for example, flattened metal angles with crossbars formed thereon, which are mechanically fixed, in particular clamped, in the longitudinal grooves 4 after being inserted into them.
- the media columns 1 of work tables 110 arranged opposite one another back-to-back are also arranged in pairs back-to-back and are screwed together to increase stability or are positively connected to one another via clamping devices or clasps.
- the media columns 1 according to the invention can be used to create mobile shelf arrangements with shelves 150 in the shortest possible time, which can be moved along the longitudinal edges 112r of the work tables 110 and offer increased security against tipping over.
- the laboratory 100 or the arrangement 102 of work tables 110 contained therein comprises a ventilation arrangement 300 arranged above the work tables 110 with a central combined supply air duct air outlet 310 and an exhaust air duct 330 arranged above it.
- the central combined supply air duct -Air outlet 310 and the exhaust air duct arranged above it are accommodated on a frame 320 made of support profiles above the workbenches 110, which is fastened to the ceiling of the laboratory room via vertical profiles.
- the frame 320 comprises pairs of horizontal profile supports 325 lying opposite one another on both sides of the central combined supply air duct air outlet 310 and extending to the side away from the latter, between and on which air guiding panels 340 are accommodated.
- the air-guiding panels 340 have a curved, downward-facing, air-guiding surface in the shape of a lying, flattened S, one longitudinal edge of which originates in the area above the associated central supply air duct 310 and the other more freely Longitudinal edge, as shown, in the upward direction I
- I is angled. Due to this curved shape of the free panel edges, which are angled upwards and are located in the area above the rear longitudinal edges 112r of the work tables 110 and form a coherent air duct surface, the air flow under the work tables 110 is controlled by laboratory equipment and/or EDP equipment (not shown). heated air rising through the gap formed along the rear longitudinal edges 112r of the workbenches 110 is deflected upwards away from the central combined supply air duct air outlet 310 into the space above the air duct panels 340 and in this to the exhaust air duct 330 located above the central combined supply air duct air outlet directed.
- This preferably has two slot-like suction openings (not shown) which extend essentially parallel to the air supply duct 310 and via which the waste air is sucked off.
- the exhaust air is separated from the fresh air supplied through the outlet openings of the central combined intake air duct/air outlet in a manner according to the invention by the air guide panels 340, which leads to an energetically very advantageous separation of intake air and exhaust air.
- the edges of the air guide panels 340 as shown in Fig.
- this advantageous design which is wing-like or swinging S-shaped in side view, of the air-guiding panels 340 arranged on both sides of the central supply air duct 310 in conjunction with the between the rear longitudinal edges to 112r of the work tables 110 results from the depth of the inherently rigid Profile gaps defined an upward flow of heated air.
- This is indicated by the arrows in Fig. 4 and, in conjunction with the curved shape of the panel edges pointing upwards, ensures a particularly effective separation of the heated, rising exhaust air from the cooled and/or cleaned supply air supplied via the central combined supply air duct air outlets 310.
- this allows the energy required to provide the central combined Zu povertykanal- air outlets 310 supplied fresh air, which over the respective, above the
- Air guide panels 340 arranged exhaust duct 330 is sucked off again, advantageously reduce considerably.
- the exhaust air ducts 330 are not shown in the illustration in FIG. 5 .
- the air guide panels 340 which can alternatively also be used without a previously described movable media column 1 in a laboratory 100, which has an arrangement 102 of worktables 110 with worktops 112 whose rear longitudinal edges 112a are separated by a gap or by an adjacent vertical wall are separated, according to a further embodiment advantageously consist of a foamed, sound-absorbing plastic material.
- the airflow panels 340 may also have sound-absorbing openings that are merely blind holes for improved separation of supply air and exhaust air, the bottoms and tops of the airflow panels 340 in the preferred embodiment are closed spatially shaped surfaces with a continuously closed surface.
- the air guide panels 340 can be folded down around pivot axes 342 only indicated in Fig. 5, preferably with their angled outer ends, in order to provide access within a very short time when moving the media columns 1 to the supply lines 120 or their flexible line sections 120a and also to the supply points 122 on the ceiling side.
- the air-guiding panels 340 In order to fix the air-guiding panels 340 in their horizontal working positions shown in FIGS. 4 and 5, they can be e.g. via spring-loaded, displaceable locking bolts, slidable, spring-loaded locking balls or the like, or also by magnetic means such as permanent magnets attached to the lateral edges of the air guide panels 340, which interact with corresponding complementary counter-means such as bores or ferromagnetic metal surfaces on the horizontal profile supports 325.
- the locking means and complementary counter means not shown in detail can also be arranged in the opposite manner on the profile supports 325 and air guide panels 340 and enable the air guide panels 340 to be released by hand, preferably without tools, and pivoted in the downward direction.
