Abstract
A passenger transport vehicle, such as a rail vehicle, has at least one sanitary module and at least one fan for conveying waste air from the sanitary module. A control unit controls the volumetric flow of waste air from the sanitary module. The control unit is formed for at least two volumetric flows of waste air, which differ from one another and differ from zero. The volumetric flows are conveyed by the at least one fan, at least on the basis of a state of the sanitary module.
Claims12
A passenger-transport vehicle, comprising:
- a sanitary module having an interior space and a space in front of the sanitary module;
- at least one fan for conveying waste air out of said sanitary module;
- and
- a closed-loop-control unit for controlling said at least one fan to generate a fan-fed volumetric flow of the waste air;
- said closed-loop-control unit being configured to control a generation by said at least one fan of at least two volumetric flows of waste air, which differ from one another and which are different from zero;
- said closed-loop-control unit being configured to control the generation of the fan-fed volumetric flow of waste air in dependence on a pressure in the interior space of the sanitary module and/or in dependence on a pressure in the space in front of the sanitary module;
- said closed-loop-control unit being configured to control the generation of the fan-fed volumetric flow of waste air in dependence on a presence of a person using the sanitary module and in dependence on a locking state of a door of said sanitary module;
- and
- said closed-loop-control unit reducing the generation of the fan-fed volumetric flow of waste air while the door of said sanitary module is locked from inside said sanitary module.
