For the development of the think tank vetroCUBE, flexibility was a priority in the specifications. The think tank should be independent of the building structure and used where it is needed. The think tank should become self-sufficient. An elementary prerequisite for this independence is the integrated ventilation of the room in room system. The think tank does NOT have to be connected to the ventilation system of the building. The capacity of the integrated ventilation system is 60 m³/h per person. The fan runs very quietly and emits only 35dB. The volume flow rate is adjusted to the size of the think tank and to the number of people who are to use the room in room system at the same time.

Slowly but continuously the offices fill up again. Many companies initially opt for a mix of company office and home office, whereby the new hygiene rules apply in the office. Our systems support these rules. Corresponding design proposals for the office space itself can be found under our headings "office space planning" and "silentUNIT".Transparent acoustic modules provide the necessary hygiene distances as well as the necessary acoustic distance to colleagues. Now, however, it is precisely the middle zone that needs special attention. This is where the areas for retreats are to be found, and it is precisely these that are particularly important for the return to communicative office work. In order to ensure that the ventilation systems room-in-room systems do not become a burden on the surrounding workplaces, we have developed a UV-supported air disinfection system for our product vetroCUBE. This system is located in the form of a self-contained cassette in the air flow of the current fan box. The air that leaves the cube is irradiated with a corresponding high-energy dose of UV light on its way through the fan box. The concept ensures that the dwell time of the air as well as the introduced energy are exactly in the target range to reliably destroy viruses, bacteria, fungi, etc. Of course, the light remains in the fan box. The design ensures that neither humans nor sensitive components are exposed to the radiation.
At this point, let's take another look at the flow velocities of the air. We will take a look at this on a common 4 person cube, measuring 3.6 x 2.6 m, as you will find it on our solutions page. Here the plant works in regular operation with 270 m³/h. We measure the following air speeds:
Inlet side of the afterflow opening: approx. 1.0 m/s, depending on the quantity and width of the solid wall elements.
Outlet side of the after-flow opening: approx. 0.7 m/s, depending on the quantity and width of the solid wall elements
Suction side of the exhaust air opening: (under the ceiling): approx. 1.0 m/2
Exhaust air opening of the fan box: (on the ceiling element - blow out direction sideways): approx. 3.6 m/s
Vertical air flow in the cube, from bottom to top: not measurable
From this it can be concluded that only the exhaust air opening of the fan box could become problematic. For this purpose we offer UV air disinfection. All other air speeds are so low that the 2 m rule applies. The distance that the aerosol has to travel from the inlet side to the outlet side of the afterflow opening is already more than 2 m. But now it is still at the bottom of the vetroCUBE. It must now first ascend (with the thermal, as described above at an unmeasurable air speed) to the head of the person. That is another 1.5 m.
Conclusion: from our point of view, the ventilation system vetroCUBE does not pose any particular danger as long as the exhaust air is disinfected.

The Think Tank's own ventilation system ensures the supply of fresh air. An acoustically optimised fan box is located on the ceiling. The exhaust air is led to the outside via two shadow gaps to the right and left of the flush LED luminaire in the ceiling element of the think tank. The fan box collects heated and used air. The supply air is secured via the solid wall elements of the think tank. Airflow openings close to the floor allow fresh air to flow in from cooler air layers. This results in optimum thermal ventilation of the think tank. The entire system is acoustically decoupled on the one hand, so that sound insulation of 37 dB is guaranteed. On the other hand, the fan box is so quiet and emits a maximum of 35 dB. This results in optimum thermal ventilation of the think tank.
It is ensured that the ventilation works "silently" on the one hand and that the sound insulation of the think tank does not suffer on the other. The entire system is acoustically decoupled so that sound insulation of 37 dB is guaranteed. On the other hand, the fan box is very quiet and emits a maximum of 35 dB. The ventilation system is maintenance-free. There are no air filters or other components to be replaced or maintained. After all, the air has the same quality as that which the colleagues breathe in the open space, so that filters, for example, are obsolete and would unnecessarily increase the air resistance.
Ventilation control is automated. A presence detector is integrated in the system ceiling. It switches on the ventilation (also the light) when entering the think tank. The ventilation then conveys at least 60 m³/h and person. Now the user can adjust the ventilation individually. For example, the ventilation can be temporarily adjusted to twice the volume flow (air shower). Within a time window of 5 minutes, the ventilation falls back to normal performance in order to run as quietly as possible. At the end of the utilisation phase, after leaving the think tank, the ventilation switches to stand-by with a follow-up time of approx. 10 minutes. The stand-by mode then only delivers a minimum quantity (approx. 50 m³/h) to keep the think tank "fresh". At night, between 10:00 pm and 6:00 am the ventilation switches off completely. All parameters can be individually changed by a stored PIN function.
If the building can offer on-site ventilation at the planned parking spaces, it is also possible to connect the think tank to the building's own ventilation system. Supply air pipes can be connected via corresponding cut-outs in the system ceiling. The exhaust air can be passively discharged via the previously described overflow openings of the solid walls. If the size of the room in room unit permits this (distance between supply air opening and exhaust air opening), both connections can be made via the ceiling. This variant makes sense above all if there is a requirement to supply the room with fresh, filtered and possibly cooled air.
