Referring first to the Fig. 1 . 2 , the workspace module is cubic. It comprises a ceiling arrangement 1, which is designed substantially plate-like and is rectangular. The ceiling arrangement 1 runs horizontally in the assembled state of the working space module.

Furthermore, the working space module has four side walls 2, 3, which adjoin each edge of the ceiling arrangement 1. Each side wall 2, 3 is plate-like and rectangular. The side walls 2, 3 each extend at right angles to the ceiling arrangement 1 and vertically in the assembled state of the working space module. The side walls 2 face each other and thus extend parallel to each other. The side walls 3 are opposite each other and thus parallel to each other. The side walls 2 may also be referred to as first side walls 2 and perpendicular to the side walls 3, which may be referred to as second side walls 3, respectively.

The side walls 2, 3 each have a height that is between 2.2 m and 2.5 m. Furthermore, each side wall 2, 3 has a width which is between 2 m and 4 m.

By the side walls 2, 3 and the ceiling arrangement 1, an inner space 4 of the working space module is limited to the outside.

The working space module also has a ventilation arrangement 5 for the ventilation thereof. The ventilation assembly 5 is located in the ceiling assembly 1. It has an elongated shape and extends parallel to the side walls 2 between the side walls. 3

The working space module is substantially symmetrical with respect to a plane of symmetry 6 which extends vertically to the side walls 3 and parallel to the side walls 2. The ventilation arrangement 5 is arranged centrally between the side walls 2 in the ceiling arrangement 1. It is also arranged centrally between the side walls 3 in the ceiling arrangement 1.

$$0,01\le \frac{\mathit{BL}}{S2}\le 0,3$$

$$0,3\le \frac{\mathit{LL}}{S3}\le 0,9$$

The ventilation arrangement 5 has a width BL, which is substantially smaller than a length LL of the ventilation arrangement 5. The side walls 2 have a distance S2 to each other, while the side walls 3 have a distance S3 to each other. In particular: $$0.03\le \frac{\mathit{BL}}{\mathit{LL}}\le 0.3$$

$$0.01\le \frac{\mathit{BL}}{S2}\le 0.3$$

$$0.3\le \frac{\mathit{LL}}{S3}\le 0.9$$

In operation, the ventilation arrangement 5 presses air or fresh air from the outside into the interior space 4 and then allows air to escape through it then also from the interior space 4 again. This is also due to the in Fig. 1 illustrated flow arrows 7 illustrates.

The ventilation arrangement 5 has a lower side 8 facing the inner space 4, which runs essentially flush with an inner side 9 of the ceiling arrangement 1. For securing the ventilation arrangement 5 in / on the ceiling arrangement 1 angle profiles 10 are provided, which are firmly connected in the mounted state of the working space module with the ventilation arrangement 5 and the ceiling arrangement 1. Horizontal leg 11 of the angle profiles 10 engage behind the ceiling assembly 1, while vertically extending legs 12 of the angle profiles 10 are each attached laterally to the ventilation arrangement 5. It is advantageous if between the angle profiles 10 and the ceiling assembly 1 sealing elements, for example made of sponge rubber, are arranged.

Hereinafter, in particular with reference to the Fig. 4 to 7 the ventilation arrangement 5 described in more detail.

The vent assembly 5 has an air flow generation device 13, which in turn comprises a fan wheel (not shown). Further, the air flow generation device 13 has a drive motor (not shown) for rotatably driving the fan wheel. In particular, there is a rotationally driven drive shaft of the drive motor with the fan wheel in non-rotatable connection. The drive motor is in electrical communication with a power source (not shown).

Preferably, the drive motor has a constant speed during operation. It is expedient if the drive motor has at least two different speed stages for driving the fan wheel at different speeds.

The drive motor can be switched on and off by a switching device 14. For this, a wiring 15 and a switching device transformer 16 are provided.

The air flow generation device 13 has a suction side 17 and a pressure side 18 opposite to the suction side 17. The air flow generation device 13 sucks fresh ambient air from the suction side 17 via the suction side 17 Outside the working space module, while the air flow-generating device 13, the sucked ambient air on its pressure side 18 again expresses or expresses. At this time, the ambient air is conveyed along a flow direction 19 in the air flow generation device 13.

Furthermore, the ventilation arrangement 5 has an air supply. The air supply includes an air supply housing 20 disposed downstream of the air flow generating device 13 and defining an air supply passage 28 for supplying air. The air supply housing 20 connects directly to the pressure side 18 and comprises sound insulation material 41. It is U-shaped in cross-section and thus has two mutually opposite side walls 21 and a this interconnecting ceiling 22. The ceiling 22 is offset from the interior space 4 to the outside.

Opposite the ceiling 22, an air passage means 23 is disposed on the air supply housing 20 at the bottom. The air passage means 23, as it were, closes the air supply case 20 toward the inside space 4, but allows inward and outward air passage, which will be described later in detail. The air passage device 23 extends over the entire length of the ventilation arrangement 5.

Opposite to the air flow generation device 13, the ventilation arrangement 5 has an air discharge outlet device 24 (FIG. Fig. 7 ). The air discharge outlet means 24 is fluidly separated from the air flow carried in the air supply casing 20. The air discharge outlet means 24 is part of the air discharge and soundproofed.

The air passage means 23 has an air outlet means 25 extending between the air flow generation means 13 and the air discharge outlet means 24, which in turn comprises two air outlets 26. The air outlets 26 are each made substantially identical and extend adjacent to and along the side walls 21. The air outlets 26 are arranged at a distance from each other. Between the air outlets 26 extends substantially over the entire length of the ventilation arrangement 5 in the air passage means 23, an air-discharge collecting channel 27th

Each air outlet 26 is in fluid communication with the air supply passage 28 defined by the air supply housing 20, and is formed by a slot diffuser 29. The slot diffusers 29 extend along the adjacent side wall 21.

The air discharge collecting passage 27 is formed by an air discharge collecting passage part 30. In the air discharge collecting channel part 30, a plurality of air discharge inlets 40 are arranged at the bottom, which open into the air discharge collecting channel 27 and the inner space 4. The air discharge inlets 40 are arranged distributed substantially over the entire length of the ventilation arrangement there.

The air discharge collecting passage 27 is also in fluid communication with the air discharge outlet means 24. For this purpose, the air-discharge collecting duct part 30 is preferably perforated in the region of the air discharge outlet device 24 with the formation of air discharge openings 38.

Downstream of the air discharge openings 38, the air discharge outlet means 24 has an intermediate air chamber 31. The air flows out of the air discharge collecting passage part 30 through the air discharge openings 38 in the air-intermediate chamber 31, which is limited by sound insulation material 39.

Laterally outside the intermediate air chamber 31, the air exhaust outlet means 24 has two return channels 32 in which the air is initially directed downwardly towards the inner space 4 but does not flow into it. The air is deflected by about 180 °. Each return channel 32 is followed by an outlet channel 33, in which the air is again led away from the inner space 4.

Between each return channel 32 and the adjacent outlet channel 33, a perforated plate 34 is arranged in each case, which extends vertically and forms an extension of a side wall 35 of an air-intermediate chamber housing 36, as it were. These side walls 35 are parallel to each other. Between these extends above a ceiling 37 of the air-intermediate chamber housing 36th

The air supply housing 20 essentially forms the air supply. The air discharge collecting duct part 30 and the air discharge outlet means 24 essentially form the air discharge.

Hereinafter, the ventilation arrangement 5 will be described in operation. In operation, the air flow-generating device 13 sucks air from its surroundings, ie from outside the inner space 4, via its intake side 17. The air is thereby moved in the flow direction 19 and flows in the air supply channel 28 away from the air flow-generating device 13. The air passes through the slot diffusers 29 and along the same from the ventilation Arrangement 5 from above into the interior space 4 a. Due to the respectively outwardly inclined slot diffusers 29, the air flows without crossing in the direction of the adjacent side wall 2, at which the air then flows down in the direction of the bottom arrangement of the working space module.

By introducing fresh air through the ventilation arrangement 5, an overpressure arises in the interior space 4. The overpressure causes that the spent air in the interior space 4 is automatically discharged through the ventilation arrangement 5 again.

The air enters the air discharge manifold 27 via the air discharge inlets 40 and then flows through the air discharge openings 38 into the air intermediate chamber 31. The air is then passed through the air discharge passage 38. Outlet outlet means 24 discharged to the outside in the environment. In this case, the air in the air-discharge device 24 is deflected twice meandering and leaves the ventilation arrangement 5 via the outlet channels 33. The air passes through hole plates 34. The deflection is a sound protection from outside to inside and from the inside guaranteed on the outside.

It is therefore introduced via the ventilation arrangement 5 fresh air from the environment in the interior space 4, while spent air flows through the ventilation arrangement 5 from the interior space 4 silenced. The fresh air is distributed substantially evenly throughout the interior space 4.
