摘要:
The invention discloses the multistage cooling of an aircraft electronic system (2) with at least one electronic component which delivers heat. The multistage feature results from the use of a plurality of circuits for transferring the waste heat. An internal coolant (14) circulating in a closed circuit which is thermally coupled to the electronic component carries heat from the at least one electronic component to a heat exchanger (6) which delivers the heat to an external coolant which flows and/or circulates from a source outside of the aircraft electronic system (2) through the heat exchanger (6) to a sink outside of the aircraft electronic system (2). The internal coolant flows from the heat exchanger (6) in the direction of the at least one electronic component and/or circulates in a closed circuit.

A system (10, 10') for cooling items of freight on board an aircraft includes a refrigerating device and also a cooling station (14, 14') to which cooling energy generated by the refrigerating device is supplied by means of a refrigerant medium. The cooling station (14, 14') is capable of being connected to a freight compartment (24) of the aircraft or to a freight container (261) on board the aircraft, in order to lead the cooling energy supplied to the cooling station (14, 14') away into the freight compartment (24) or into the freight container (261). A freight container (261) for receiving items of freight designated for transportation on board an aircraft is capable of being connected to a cooling station (14') of a system (101) for cooling items of freight on board an aircraft, so that the cooling energy supplied to the cooling station (141) is capable of being led away into the freight container (26'). An alternative system (10') for cooling items of freight on board an aircraft includes a refrigerating device that is capable of being connected to a cooling station (14'), in order to supply cooling energy generated by the refrigerating device to the cooling station (14') by means of a refrigerant medium. The cooling station (14') is integrated into a freight container (26') for receiving items of freight designated for transportation on board an aircraft and is set up to lead the cooling energy supplied to the cooling station (14') away into the freight container (26'). A corresponding freight container (26') includes a cooling station (14') integrated into the freight container (26'), said cooling station being capable of being connected to a refrigerating device of a system for cooling items of freight on board an aircraft, in order to supply cooling energy generated by the refrigerating device to the cooling station (14') by means of a refrigerant medium, said cooling energy being capable of being led away through the cooling station (14') into the freight container (26').
摘要:
A system (10) for air conditioning an aircraft cabin (12) comprises an air-conditioning unit (14), which is connected to a central mixer (16) to supply air at a desired low temperature to the central mixer (16). A first recirculation system (18) is equipped to remove exhaust air from a first aircraft cabin area (12a) and is connected to the central mixer (16) in order to conduct the exhaust air from the first aircraft cabin area (12a) into the central mixer (16). A second recirculation system (24) is equipped to remove exhaust air from a second aircraft cabin area (12b) and is connected to a local mixer (20, 22) to conduct the exhaust air from the second aircraft cabin area (12b) into the local mixer (20, 22). The local mixer (20, 22) is connected to the central mixer (16) in order to supply mixed air from the central mixer (16) to the local mixer (20, 22). The second recirculation system (24) comprises a cooling unit (28), which is arranged upstream of the local mixer (20, 22) in the second recirculation system (24), based on the direction of flow of the recirculation air removed from the second aircraft cabin area (12b), and is equipped to cool the recirculation air removed from the second aircraft cabin area (12b) to a desired temperature.
摘要:
A cooling system (10) for cooling an aircraft device (12) comprises an evaporator (14, 16, 18) for receiving a fluid (F) which is to be evaporated, a first adsorber (24) which contains a medium (28) for the adsorption of the fluid (F) which is evaporated in the evaporator (14, 16, 18), as well as a second adsorber (26) which contains a medium for the adsorption of the fluid (F) which is evaporated in the evaporator (14, 16, 18). A control system (22) is adapted to establish or to interrupt a fluid connection between the evaporator (14, 16, 18) and the first and/or the second adsorber(s) (24, 26).
