Definitions
- the present invention relates to a system and a method for air conditioning of an aircraft cabin.
- the cabin of a modern passenger aircraft is usually conditioned both in flight operation and in ground operation of the aircraft by means of an aircraft-specific air conditioning system.
- the aircraft air conditioning system is supplied to the engine compressors or auxiliary engine compressors drawn bleed air, which is cooled in the air conditioning units, the so-called air conditioning of the aircraft air conditioning system to a desired low temperature.
- the cooled air in the air conditioning of the aircraft air conditioning system is passed into a mixer, where it is mixed with extracted from the aircraft cabin i5 recirculation air.
- the mixed air generated in the mixer from cold air supplied by the air-conditioning packs and recirculation air extracted from the aircraft cabin is finally introduced into the aircraft cabin for the purpose of air-conditioning the aircraft cabin.
- an air-conditioning system described, for example, in DE 44 25 871 C1 which comprises two recirculation systems for extracting exhaust air from the aircraft cabin.
- a low pressure recirculation system extracts air from an upper deck area of the cab, while a high pressure recirculation system serves to extract air from a middle deck area of the cab.
- the recirculation air discharged from the high deck recirculation system from the center deck area of the cabin is blown into a central mixer of the aircraft air conditioning system.
- the air drawn from the upper deck area of the cabin by the low pressure circulation system is supplied to local mixers fed by the central mixer with premixed air, ie an air mix of cold air supplied by the air conditioning packs and recirculation air from the center deck area of the cabin.
- premixed air ie an air mix of cold air supplied by the air conditioning packs and recirculation air from the center deck area of the cabin.
- the air mixture of premixed air from the central mixer and recirculation air from the upper deck area of the cabin, generated in the local mixers, is finally used for air conditioning of the aircraft cabin.
- air is directed from a local mixer arranged in the region of the middle deck into the middle deck area of the cabin, while air is arranged from one in the area of the upper deck local mixer is blown into the upper deck area of the cabin.
- An air conditioning system equipped with two recirculation systems is designed so that both recirculation systems must always provide a defined minimum airflow to ensure adequate ventilation of the aircraft cabin. During operation of the aircraft air conditioning system, it is therefore not possible to switch off a recirculation system or both recirculation systems. During operation of the recirculation systems, however, additional heat loads are generated by the waste heat generated by the blowers of the recirculation systems. The cooling energy required to cool the recirculation fans must be provided by the air conditioning system so that the operation of the recirculation systems reduces the cooling power available for cooling the aircraft cabin.
- the additional heat input of the recirculation systems can significantly increase the time required to cool the aircraft cabin to a desired temperature.
- the air conditioning then requires a longer lead time until the cabin has cooled sufficiently and can begin with the boarding of the passengers. This delays the handling of the aircraft at the airport. Since the A / C system is supplied with bleed air by the A / C compressors during this phase of operation, the increased lead time of the A / C system further increases fuel costs. Finally, the auxiliary engine operating time is extended, which can lead to higher maintenance costs.
- the invention is directed to the object of providing a system and a method for the air conditioning of an aircraft cabin, which allow a shortening of the time required for cooling the aircraft cabin in ground operation of the aircraft.
- An aircraft cabin air conditioning system comprises an air conditioning unit connected to a central mixer for supplying air at a desired low temperature to the central mixer.
- the air conditioning unit may be supplied with bleed air from the engine compressors or the auxiliary engine compressors of the aircraft under an increased pressure.
- a first Recirculation system of the air conditioning system according to the invention is adapted to remove exhaust air from a first aircraft cabin area.
- the first recirculation system may comprise a plurality of air outlet openings arranged in the first aircraft cabin area, which are formed, for example, in a ground-level sidewall area or in a floor area of the first aircraft cabin area.
- the first recirculation system of the air conditioning system according to the invention is further connected to the central mixer to direct the exhaust air discharged from the first cabin area into the central mixer.
- the air conditioning system comprises a second recirculation system, which is adapted to remove exhaust air from a second aircraft cabin area.
- the second recirculation system may also comprise a plurality of air outlet openings which are formed in a bottom-side sidewall region or in a bottom region of the second aircraft cabin region.
- the first aircraft cabin area can be, for example, a middle deck area of the aircraft cabin.
- the second aircraft cabin area may then be, for example, an upper deck area of the cabin.
- the second recirculation system is connected to a local mixer to direct the exhaust air from the second aircraft cabin area to the local mixer.
- the air conditioning system may also comprise a plurality of local mixers.
- a system for air conditioning the cabin of a wide-bodied aircraft with two passenger decks may, for example, comprise a first local mixer arranged in the area of the mid-deck and a second local mixer arranged in the area of the upper deck.
- the local mixer is connected to the central mixer.
- the mixed air generated by the air conditioning unit and provided by the air conditioning unit cold fresh air and recirculation air from the first aircraft cabin area can thus be passed from the central mixer in the local mixer.
- the mixed air supplied from the central mixer is finally mixed with the recirculation air discharged from the second aircraft cabin area before the mixed air is passed from the local mixer into the aircraft cabin.
- the mixing air can be used from a the region of a middle deck angeord ⁇ Neten first local mixer to air-condition the middle deck region of the aircraft cabin, while the mixed air from a one in the field - A -
- Upper deck arranged local mixer can be used to air condition the upper deck area of the aircraft cabin.
- the system according to the invention for air conditioning of an aircraft cabin further comprises a control device, which is set up to control the second recirculation system in normal operation of the air conditioning system such that the second recirculation system discharges a predetermined air volume flow from the second aircraft cabin area.
- the control device may be, for example, an electronic control device.
- the air volume flow discharged from the second aircraft cabin area by the second recirculation system is approximately equal to the air volume flow discharged from the first aircraft cabin area by the first recirculation system.
- control device of the system according to the invention for air conditioning of an aircraft cabin is further configured to control the second recirculation system in certain operating situations of the air conditioning system such that the air volume flow discharged from the second aircraft cabin area by the second recirculation system is greater than that during normal operation of the air conditioning system
- control device 20 is designed to reduce the power of the second recirculation system in certain operating situations of the air conditioning system, but without completely setting the operation of the second recirculation system.
- the idea on which the present invention is based is based on the finding that, in particular, the additional heat load, which arises as a result of the waste heat generated by the blowers of the second recirculation system, has a negative effect on the air conditioning performance of the overall system.
- the cause of this effect o is the fact that the exhaust air discharged from the second aircraft cabin area, which is additionally heated by the waste heat of the components of the second recirculation system, is fed into the local mixer, where it does not have cold fresh air generated by the air conditioning unit but only mixed with pre-mixed and thus preheated mixed air from the central mixer before being returned to the second aircraft cabin area.
- the amount of waste heat generated by the blowers of the second recirculation system can be reduced.
- less heat exhaust air is supplied to the local mixer from the second aircraft cabin area. This allows a much more efficient
- the air conditioning system according to the invention thus enables a rapid cooling of the aircraft cabin even in ground operation of the aircraft on hot days. As a result, it is easier to start boarding passengers, thus shortening the time the aircraft takes to leave the airport. In addition, the operating times of the auxiliary power unit to supply the air conditioning unit with bleed air are reduced, which fuel savings and lower maintenance costs can be realized.
- Another advantage of the air conditioning system of the invention is that it is weight neutral, i. Optimized utilization of the cooling capacity of the air conditioning unit without additional weight.
- the control device of the air conditioning system is preferably configured to evaluate at least one predetermined parameter and to control the second recirculation system as a function of the evaluation of the at least one predetermined parameter.
- the evaluation of the at least one predetermined parameter is used to determine the utilization status of the air conditioning unit and components associated with the air conditioning unit.
- the evaluation of the at least one predetermined parameter can serve to detect the presence of an operating situation in which a reduction of the additional heat input caused by the second recirculation system is desired or required.
- the control means may so control the second recirculation system that discharged from the second recirculation system from the second aircraft cabin area air volume flow is reduced only with respect to the discharged from the second recirculation system from the second aircraft cabin area during normal operation of the air conditioning system predetermined HeilVO ⁇ volume flow when the air conditioning unit is not yet fully utilized, ie the air conditioning unit is still in an operating state, in which it can provide additional cooling power.

- control device of the system according to the invention for air conditioning of an aircraft cabin can be set up to control the first recirculation system such that the air volume flow discharged from the first aircraft cabin area by the first recirculation system is out of the first aircraft cabin area by the first recirculation system during normal operation of the air conditioning system removed predetermined air volume flow is increased.
- the amount of recirculation air supplied to the central mixer is increased and the loss of recirculation air is at least partially compensated by the reduction of the power of the second recirculation system.
- the increase in the output of the first recirculation system increases the amount of waste heat generated by the first recirculation system
- the additional heat input produced by the first recirculation system has a much smaller effect on the cooling capacity of the overall air conditioning system than that of the first recirculation system additional heat input generated by the second recirculation system during operation, as the heated by the waste heat of the blower of the first recirculation system air from the first cabin area is passed directly into the central mixer and mixed with cold fresh air.
- the cooling of the air 5 in the aircraft cabin is therefore hardly delayed by an increase in the output of the first recirculation system.
- the control device is configured to control the first recirculation system such that the air volume flow discharged from the first aircraft cabin area by the first recirculation system is greater than that of the first recirculation system during normal operation of the air conditioning system first predetermined air volume flow is increased by an amount which is equal to the amount by which the i5 of the second recirculation system from the second cabin area reduced air volume flow compared to the normal operation of the air conditioning system from the second recirculation system discharged from the second aircraft cabin area predetermined air volume flow ,

- the second recirculation system is controlled by the control device such that the air volume flow discharged from the second aircraft cabin area by the second recirculation system is reduced compared to the air volume flow discharged from the second aircraft cabin area by the second recirculation system during normal operation of the air conditioning system.
- the control device preferably evaluates at least one predetermined parameter and controls the second recirculation system as a function of the evaluation of the at least one predetermined parameter.

- control means controls the former recirculation system such that the discharged from the first recirculation system from the first aircraft cabin area air volume flow is increased compared to a discharged from the first recirculation system from the first aircraft cabin area during normal operation of the internal climate ⁇ sticianssystems predetermined air flow rate.
- the control device controls the first recirculation system such that the air flow discharged from the first aircraft cabin area by the first recirculation system is reduced by an amount from the predetermined air volume flow discharged from the first aircraft cabin area by the first recirculation system during normal operation of the air conditioning system which is equal to the amount by which the air volume flow discharged from the second aircraft cabin area by the second recirculation system is reduced compared to the predetermined air volume flow discharged from the second aircraft cabin area by the second recirculation system during normal operation of the air conditioning system.
