Problems solved by technology

However, this requires a relatively large bleed air duct through the cabin
This is undesirable since the bleed air duct requires additional space and adds weight to the aircraft

Embodiment Construction

[0050] The cabin of an aircraft is usually divided into zones, which are considered zones at respective desired temperatures. Each zone may include its own temperature regulation or temperature control. Zones typically have only slightly different desired temperatures. However, the heat load in a zone can vary greatly due to eg passenger density and number of devices emitting waste heat. The desired temperature of the air jets supplied to the zones depends on the heat load in the individual zones and thus can vary widely. Areas with a high heat load correspondingly need to be supplied with air at a lower desired temperature.

[0051] figure 1 An embodiment of the invention is shown in which air is supplied directly from the central air-conditioning system 2 to the cabin areas requiring the greatest air volume flow without being cooled or heated by additional cooling or heating devices. An air flow 4 , which may include engine bleed air and / or recirculated air 50 from the c...

Abstract

An air conditioning system for an aircraft for the individual air conditioning of regions of a cabin of an aircraft includes a central air conditioning device, which provides a pressurized and temperature-controlled central air flow. A part of the central air flow is supplied to a first cabin region. Another part of the central air flow is heated in a heating device or cooled in a cooling device and supplied to another cabin region. Water evaporates in the cooling device, in order to cool the air flow to be supplied to the cabin region.

Description

technical field [0001] The invention relates to the individual temperature control of regions of an aircraft cabin by means of evaporative cooling and heating. Background technique [0002] In the case of an aircraft having a cabin that is divided into zones, it is often desirable to be able to air condition the various zones to different temperatures. For example, economy class may have a different temperature than business class. In First Class Suites, the temperature can be set individually. The temperature in business class is usually preset centrally. However, a passenger can individually set the ambient temperature of his or her seat so that the ambient of that seat is supplied with cooler or warmer air than the rest of the business class area. By air-conditioning the compartments individually, different heat loads in these areas can be taken into account. [0003] Figure 5 shows a conventional system for air conditioning a sub-area of ​​an aircraft. The central a...
