Abstract
Aircraft air-conditioning system () for an aircraft having a plurality of zones (), comprising a first line () for feeding cold air at an actual temperature T, a second line () which branches off a portion of the air from the first line () at a branching point () and feeds the air to a plurality of zones () of an aircraft, wherein warm air is fed through a first trim valve () into the second line () so that the air in the second line () is heated to the actual temperature T, and a first zone feed line () feeding the air downstream of the first trim valve () to a first zone (), wherein a second trim valve () is arranged in the first zone feed line (), through which valve warm air is fed into the first zone feed line () so that the air in the first zone feed line () is heated to the actual temperature Tzf, and the first line () downstream and/or upstream of the branching point () feeds cold air at least to one further zone. A second feed line () feeds air downstream of the first adjustment () to a second zone (). A heating device () can be arranged in the second feed line ().
