Abstract: A method for disinfecting a water system of an aircraft includes letting-in of hot water at an inlet of the water system by a first ground service unit; flushing the hot water from the inlet, through water pipes of the water system, to an outlet of the water system; and letting-out of the hot water at the outlet, by the first ground service unit or a second ground service unit; the hot water being flushed into the inlet and out of the outlet over a predefined disinfection period; and the hot water being provided at the inlet via a continuous-flow heater of the first ground service unit.

Abstract: A method for disinfecting a water system of an aircraft includes the introduction of damp hot air at an inlet of the water system by a ground service unit; flushing of the damp hot air from the inlet through water pipes of the water system to an outlet of the water system; and extraction of the damp hot air at the outlet; wherein the damp hot air is flushed into the inlet and out of the outlet over a predefined disinfection period, and wherein the damp hot air has a temperature between 60° C. and 80° C.

Abstract: An aircraft has: an aircraft fuselage, a cabin region formed in the aircraft fuselage, underfloor region separated from the cabin region by a floor partition, and a fresh-water supply system. The fresh-water supply system has a fresh-water provision unit arranged in the underfloor region. The fresh-water supply system has multiple water extraction units which are each arranged in the cabin region, and a water line network branched off from the fresh-water provision unit and extending to the water extraction units. Each water extraction unit has a shut-off valve, a filter unit and a tapping point, which are coupled in series by means of water lines. Each filter unit has an exchangeable water filter with a first filter material designed for filtering particles out of the water flowing through the water filter and with a second filter material designed for softening the water flowing through the water filter.

Abstract: A draining device for draining a fluid line is provided. The draining device comprises a mechanically non-locking coupling and a holding device. The mechanically non-locking coupling is configured to establish a fluid conductive connection with the fluid line. The holding device is configured to stationary fix the mechanically non-locking coupling relatively to the fluid line. The draining device allows establishing a fluid conductive connection between the fluid line and the mechanically non-locking coupling without requiring a mechanical fixation directly at the mechanically non-locking coupling.

Abstract: Water supply vehicle comprising a water reservoir, a flow through descaling device having a water inlet, a water outlet, a detecting device for detecting a water characteristic in a water flow from the water inlet to the water outlet, a controllable water descaling device, and a controlling device being designed for controlling the water descaling device based on a water characteristic detected by the detection device, wherein the water reservoir is connected to the water inlet, wherein the water outlet is connectable to a water hose for supplying water to a water consumer.

Abstract: A thermally optimised circulation fluid system is proposed which comprises a circulation line, a circulation pump unit and a control unit. The circulation pump unit and the circulation line together form a circulation circuit. The circulation pump unit is configured for transferring an amount of thermal energy directly or indirectly to a fluid located in the circulation line. The control unit is configured for adjusting the amount of thermal energy which is transferrable to the fluid.

Abstract: A water supply module 10? for a transportation means comprises a receiving connection 16? for receiving water from a supply line, a delivery connection 20? for delivering water to a faucet 30?, a control connection 22? for receiving control commands of an actuating element 76 on the faucet 30?, and a control unit 80. The control unit 80 is designed, on the basis of control commands of the actuating element 76, to adjust the delivery of water from the delivery connection 20? to the faucet 30?. The water supply module 10? is designed as an assembly.
