Arrangement for air conditioning passenger aircraft underfloor areas has separate branch line with air passage of defined diameter delivering air to underfloor area with sleeping containers

摘要

The arrangement has an air mixer unit for fresh and recirculated air that recirculates temperature-controlled mixed air with a main air feed line (31) to the underfloor area. Used air passes from the underfloor area outside the aircraft via a main waste airline. A separate branch supply line (19) delivers branched mixed air to a first underfloor area (20) fitted with sleeping containers and has an end flange (23) with a joint and a flap (24) with an air passage opening (26) of defined diameter.
