Embodiment Construction

[0047] figure 1 Shown is a mixer assembly 10 suitable for use in an aircraft air conditioning system and comprising a first fresh air line 12 connecting a first air conditioning unit 14 to a first premixer 16 . In a similar manner, the second fresh air line 18 connects the second air conditioning unit 20 to the second premixer 22 . During operation of the mixer assembly 10 , cool fresh air generated by the first air conditioning unit 14 and the second air conditioning unit 20 flows through the first fresh air line 12 and the second fresh air line 18 .

[0048] The mixer assembly 10 further includes a first recirculation air line 24 for delivering recirculation air from the aircraft cabin into the first pre-mixer 16 . In order to convey recirculation air via the first recirculation air line 24 , a first conveying device 26 is arranged in the first recirculation air line 24 . For example, the first conveying device 26 is configured in the form of a blower. In order to filter ...

Abstract

A mixing device for an aircraft air conditioning system includes a plurality of cold-air supply lines, which are devised to supply cold air to the mixing device. A plurality of warm-air supply lines is further provided, which are devised to supply warm air to the mixing device. A first premixing chamber is connected to the cold-air supply lines and devised to mix the cold air that is fed through the cold-air supply lines into the first premixing chamber. A second premixing chamber is connected to the warm-air supply lines and devised to mix the warm air that is fed through the warm-air supply lines into the second premixing chamber. Finally, a main mixing chamber is connected to the first and the second premixing chambers and devised to mix the cold air premixed in the first premixing chamber with the warm air premixed in the second premixing chamber.

Description

technical field [0001] The invention relates to a mixer assembly for an aircraft air conditioning system, a method of operating such a mixer assembly and an aircraft air conditioning system equipped with such a mixer assembly. Background technique [0002] In modern airliners, the passenger cabin or its subsidiary areas, the cargo compartment or its subsidiary areas, the cockpit and the crew rest area form various air-conditioning areas, which are usually passed through the aircraft's air-conditioning system during the flight and taxiing of the aircraft Get air-conditioned. Hot bleed air is removed from the engine compressor or auxiliary engine compressor at elevated pressure and supplied to the aircraft's air conditioning system. In the air-conditioning unit of the aircraft air-conditioning system (the so-called air conditioning unit), this bleed air is expanded and cooled to the desired low temperature. Finally, the air conditioned in the air conditioning unit is fed as ...
