Air Conditioning Arrangement For An Aircraft With A Plurality Of Climate Zones That May Be Individually Temperature-Controlled

摘要

An air conditioning arrangement (22) for an aircraft (10) or other premises with a plurality of climate zones (12 to 20) that may be individually temperature-controlled, comprises a main branching system (26) comprising an air supply feed path system (24) with a mixing chamber (28) and a plurality of sub-branching systems (30) branching from the mixing chamber and leading to one of the climate zones in each case. Basic temperature control means (32) are used for controlling the temperature of the air supply in the mixing chamber (28) as a function of at least one desired temperature value. Individual temperature-control means (36, 38, 40, 42) are used on the other hand for individually controlling the temperature of the air supply in each of the sub-branching systems (30) as a function of a desired temperature value of the respective climate zone. According to the invention the individual temperature-control means, in allocation to at least one (20) of the climate zones, comprise at least one combined heat and power engine (42) operating according to a thermodynamic cyclic process, in particular a Stirling engine. Basic temperature control of the air supply in the mixing chamber preferably takes place independently of a temperature requirement of the climate zone (20) with associated combined heat and power engine, and instead takes place as a function of temperature requirements solely of those climate zones (12 to 18) in which the individual temperature control of the air supply takes place in the associated sub-branching systems by feeding in bleed air or/and by means of electrical heating units.
