Problems solved by technology
[0003] There is such a problem in the above-mentioned system that in case all the air-conditioning units fail, the flow control device reduces the amount of hot air directed into the air-conditioning units to zero to prevent the air-conditioning units from being damaged by the hot air
However, at the normal flight altitude of the aircraft, and even on low-flying aircraft in cold regions, the ambient temperature may be 50°C or even 60°C lower. The air drops below 18°C
However, such low internal temperatures are unacceptable for aircraft passengers or their crews without additional protection

Embodiment Construction
[0015] attached picture A part of a device 10 for heating an aircraft cabin (not shown) is schematically shown. The shown device 10 relates to a device for use on aircraft of the type whose aircraft cabin includes several climatic zones—that is, the temperature is not the same throughout the cabin, but varies according to the climatic zone. Make different adjustments.
[0016] The plant 10 comprises two first hot air supply lines 12 into which air is drawn from one or more aircraft engines and / or auxiliary engines (auxiliary power units). The hot air from an aircraft engine is often called bleed air.
[0017] Each first hot air supply line 12 leads hot air to an air conditioning unit 14 which cools the intake air to the minimum temperature required for the climate zone of the aircraft having the lowest temperature. A flow control valve 16 is provided in each first hot air supply line 12 to monitor and control the flow of hot air to each air conditioning unit 14 .

The invention relates to a device (10) for heating an aircraft cabin and comprises a first hot air supply line (12) that leads to an air conditioning unit (14), a flow control valve (16) that is disposed in the first hot air supply line (12) upstream from the air conditioning unit (14), and a second hot air supply line (18) that branches off from the first hot air supply line (12) between the flow control valve (16) and the air conditioning unit (14) and bypasses the air conditioning unit (14). In order to assure air conditioning of the aircraft cabin in the event of a failure of the air conditioning unit (14) a third hot air supply line (20) branches off from the first hot air supply line (12) upstream from the flow control valve (16), which third hot air supply line (20) connects the first hot air supply line (12) to the second hot air supply line (18). Further a first close off mechanism is disposed in the second hot air supply line (18) upstream from the junction with the third hot air supply line (20), which first close off mechanism in its closed position prevents a flow from the second hot air supply line (18) back into the first hot air supply line (12). Finally a second close off mechanism is disposed in the third hot air supply line (20) upstream from the junction with the second hot air supply line (18).
Description
technical field [0001] The invention relates to a device for heating an aircraft cabin according to the preamble of claim 1 and a method for heating an aircraft cabin according to the preamble of claim 9 . Background technique [0002] To control the temperature of an aircraft cabin, hot air is usually obtained from the aircraft's engines. This hot air, called bleed air, passes through an air line that includes a flow control valve to control the flow to the air conditioning unit where it is cooled to the temperature required in the aircraft cabin . Different climate zones (climate zones) are set in the aircraft cabin, and it is also known that the obtained hot air is cooled to the minimum temperature required by each climate zone through an air conditioning unit. In order to supply air to climate zones that require higher temperatures, A certain amount of hot air is guided upstream of the air conditioning unit and mixed with the air cooled by the air conditioning unit acc...
