optimized abtauregelungsanordnung and procedure for parallel arranged frischluftauslu00e4ssen of air-conditioning

摘要

The present invention relates to an arrangement for deicing pipeline connections of an aircraft, which are connected to all fresh air outlets of an air conditioner, whose construction comprises the functions of multiple turbines and heat exchangers, having a first pipeline (1), which is connected to a first turbine (TA), and a second pipeline (2), which is connected to a second turbine (TB), the two pipelines (1, 2), which are each connected downstream from the two turbines (TA, TB) and to which process air is fed at the turbine outlets, being connected at the pipe ends and being continued using a third pipeline (3). The arrangement is characterized in that a first hot air source (11) is fed hot fresh air from a bleed air system of the aircraft and is connected at its outlet to a fourth pipeline (4), into which temperature-reduced fresh air is fed from the hot air source (11). The fourth pipeline (4) is connected at its pipe end to two further valve-regulated pipelines (5,6), of which a fifth or a sixth pipeline (5, 6) is connected to the first or the second pipeline (1, 2), and through which temperature-reduced fresh air is transported and fed valve-regulated to the first and/or second pipeline (1, 2).
