List of components installed in a ceiling. Luftdrall, maybe, instead of Luftdrahl? Can anybody help? It would be much appreciated. Thank you in advance.

: Drallauslass = swirl diffuser (Luft / air) is redundant.

mixed air flow ventilation
Yes, I think it should be Luftdrall.
Dralldurchlässe sind eine optisch anspruchsvolle und effiziente Lösung zur Erzeugung von Mischluftströmungen. Sie sind auch für den schnellen Austausch eines großen Luftvolumens und damit sowohl für kleine als auch für große Räume geeignet.

Mixed flow distribution is the traditional method of supplying air to ventilated spaces. Cool air is blown in through the ceiling or wall and dilutes the room air in an attempt to provide an even temperature and contaminant level through the space.
With mixed flow ventilation the flow is driven by the inertia of the supply air. The volume of the air supplied for mixed flow ventilation is calculated proportionally to the supply air and room air temperature.
Mixed flow Air conditioning Is mixing The Return Air from building with the fresh air coming from outside building into the AHU before supplying again to the building

Reference:
Your assumption seems to be correct
These are "Luftdrallauslässe" (rare term), as referred to at https://www.baunetzwissen.de/altbau/objekte/kulturbauten/aus... ("Einige Luftdrallauslässe in den Putzflächen und sparsam angeordnete Wand- oder Deckenstrahler, die zum Teil in Lichtschienen flexibel platziert werden können, zeigen den Stand heutiger Museumstechnik."), although "Dralldurchlässe" appears to be used much more frequently - see https://www.heinze.de/produktserie/dralldurchlaesse/9674754/...
