    • An air conditioning system for a pressurized aircraft body includes an air flow closed loop into which fresh air may be introduced either through a fresh air treatment unit or through a trim valve or through both. A first series connection of system components includes a fresh air intake (FA), a closed loop controlled volume flow control valve (FCV) (11, 11.1, 11.2), an air-conditioner (8, 8.1, 8.2), an air mixer (9), and the space (10) to be air-conditioned interconnected by air ducts. A cabin pressure closed loop control (1) controls the air volume through the (FCV) valve. The air-conditioner unit (8) is controlled by an air conditioning closed loop control (2). A second series connection includes a filter (7), a blower (6), and a heat exchanger (4) and preferably a CO.sub.2 adsorber (5) series connected between the blower (6) and the heat exchanger (4). This second series connection forms a recycling circuit flow connected in parallel to the air mixer (9) and to the space (10). The air mixer (9) receives recirculated air from the second series connection and fresh air from the air-conditioner (8). The blower (6) and the heat exchanger (4) are controlled by a cabin zone closed loop control (3) which receives sensor information for the closed loop control. A trim air duct (12A) with a respective trim air valve (12) also controlled in closed loop fashion, is connected to by-pass the first series connection except the space (10) so that trim air can be added to the recycling air just upstream of the space (10). Up to 85% vol. % of cabin air is recycled which minimizes the use of fresh air, for a reduction of the fuel consumption.
    • 用于加压飞行器主体的空调系统包括气流闭合回路,新鲜空气可以通过新鲜空气处理单元或通过调节阀或通过两者而被引入新的空气流闭合回路中。 系统组件的第一串联连接包括新鲜空气进入口(FA),闭环控制体积流量控制阀(FCI)(11,11.1,11.2),空调器(8,8.1,8.2),空气调节器 (9)和由空气管道相互连接的空调(10)。 机舱压力闭环控制(1)通过(FCV)阀控制风量。 空调单元(8)由空调闭环控制(2)控制。 第二串联连接包括过滤器(7),鼓风机(6)和热交换器(4),优选地连接在鼓风机(6)和热交换器(4)之间的CO 2吸附器(5)。 该第二串联连接形成与空气混合器(9)并联连接到空间(10)的回收回路。 空气混合器(9)接收来自第二串联连接的再循环空气和来自空调(8)的新鲜空气。 鼓风机(6)和热交换器(4)由一个客舱区闭环控制(3)控制,它接收闭环控制的传感器信息。 具有也以闭环方式控制的相应修剪空气阀(12)的修剪空气管道(12A)被连接以绕过除了空间(10)之外的第一串联连接,使得修整空气可以被添加到再循环空气 就在空间的上游(10)。 高达85%vol。 客舱空气的百分比被回收,这最小化了新鲜空气的使用,从而降低了燃料消耗。

    • With a method for controlling the temperature of feed air which is injected into the cabin zone of a passenger aircraft, the cabin of which is sub-divided into several cabin zones supplied respectively with specially temperature-controlled feed air, the temperature of the injected feed air is controlled for each cabin zone, dependent upon the deviation of an injection temperature actual value for the feed air injected into the cabin zone in question, measured by sensors, in relation to an injection temperature optimum value. If there is no, or at least no usable reading of the ambient temperature of this cabin zone for a cabin zone, an optimum value for the injection temperature of this cabin zone can be established in accordance with a variation, whereby it is determined upon the basis of the injection temperature optimum values and/or the injection temperature actual values of other cabin zones, whereby the measurement by sensors of the cabin temperature works reliably. In accordance with another variation, the injection temperature optimum value of a cabin zone can be established without measuring ambient temperature by sensors or without reliably measuring ambient temperature from the temperature measured for the external surrounds of the aircraft.
    • 使用一种用于控制喷射到客机的客舱区域中的进料空气的温度的方法,其将舱室分成几个舱区,分别提供特别温度控制的进料空气,喷射进料的温度 根据喷射温度最佳值,根据传感器测量的注入到所述舱室区域的进料空气的喷射温度实际值的偏差,对每个舱室进行空气控制。 如果对于客舱区域没有或至少没有可用的该舱室区域的环境温度读数,则可以根据变化确定该舱区域的喷射温度的最佳值,由此根据 喷射温度最佳值和/或其他舱区的喷射温度实际值的基础,由此由客舱温度的传感器进行的测量可靠地工作。 根据另一个变化,可以建立客舱区域的喷射温度最佳值,而不需要通过传感器测量环境温度,或者不会从对飞行器的外部环境测量的温度可靠地测量环境温度。
