ZuluftLuftbehandlungsgerät
ZuluftLuftbeha... appears to be a truncated compound that could refer to a supply-air reservoir or a device that combines supply air with an air vessel (Luftbehälter) in HVAC or ventilation systems. It is not a widely established term in English-language engineering literature, but in German-language contexts it could describe a vessel connected to the supply-air ductwork designed to store a volume of conditioned air for system stabilization.
Such a device serves to decouple dynamic demand from the supply, dampen pressure and flow fluctuations, and
Typical construction includes a pressure-rated shell with inlet and outlet connections, relief or vent lines, and
Design considerations involve sizing the reservoir to match peak flow, expected dwell time, and allowable pressure
