Abstract

Embodiments of the present invention provide a water management system for use on board a passenger transport vehicle. The water management system may be used to address and manage excess humidity, water leaks, or any other instance when water or other liquid may collect at a certain location. The disclosure provides a system for managing excess water and for optionally delivering the water to another location. The removal location may be a disposal outlet or it may be a beneficial use of the collected water on-board the vehicle.

First claim

What is claimed is:

1. A water management system for use on-board an aircraft, comprising:
(a) a water collection device comprising one or more areas for receiving moisture or water, the water collection device fluidly coupled to a source of vacuum;
(b) a conduit between the water collection device and a removal location to which the moisture or water is to be removed, through which there is created a pressure differential to cause the moisture or water to be pulled into and through the conduit;
(c) a valve to control passage of moisture or water through the conduit;
(d) a controller that directs opening and closing of the valve based on water levels sensed by a water sensor, wherein the valve is opened and closed periodically throughout an entire flight duration, wherein the water sensor comprises a flow detection sensor, a pressure sensor, a current sensor, a temperature sensor, or any combination thereof.

2. The water management system of claim 1 , wherein the collection device comprises a tube.

3. The water management system of claim 2 , wherein the tube comprises one or more perforations, openings, or holes into which moisture flows.

4. The water management system of claim 1 , wherein the collection device comprises a mat.

5. The water management system of claim 4 , wherein the mat comprises one or more perforations, openings, or holes into which moisture flows.

6. The water management system of claim 1 , wherein the one or more areas for receiving moisture comprise perforations or openings.

7. The water management system of claim 1 , wherein the water collection device, the conduit, or both are heated for freeze protection.

8. The water management system of claim 1 , wherein at least a portion of the water collection device or the conduit or both is coated with, impregnated with, or associated with an anti-microbial agent.

9. The water management system of claim 1 , wherein the water sensor comprises a water sensor for detecting leaks in the vehicle.

10. The water management system of claim 9 , wherein the water sensor measures conductivity.

11. The water management system of claim 9 , wherein the water sensor is mounted above the water collection device, fitted in various sections of the water piping and plumbing system to detect inflow velocity change, or both.

12. The water management system of claim 1 , further comprising a descaling device.

13. The water management system of claim 1 , wherein the water sensor comprises an artificial haircell sensor, a smart hair sensor, or both.

14. The water management system of claim 13 , wherein the artificial haircell sensor comprises a cilium extending from a piezoelectric base.

15. The water management system of claim 13 , wherein the smart hair sensor comprises carbon nanotubes.

16. The water management system of claim 1 , wherein the water sensor functions via piezoresistance.

17. The water management system of claim 1 , wherein the water sensor comprises a pressure sensor, a temperature sensor, and one or more flow sensors.

18. The water management system of claim 1 , further comprising a control system that directs collected water to a desired removal location.

19. The method of claim 18 , wherein the removal location comprises an aircraft drain mast, a filtration system, an aircraft grey water flush system, an aircraft humidifier system, an aircraft waste tank, or any combination thereof.

20. The water management system of claim 1 , wherein the water sensor is retrofitted into the conduit.

21. The water management system of claim 1 , wherein the water sensor is monitored wirelessly.

22. A method for collecting and removing undesired moisture or water from a location on an aircraft, comprising:
(a) causing installation of a water management system on the aircraft, the water management system comprising: (i) a water collection device comprising one or more areas for receiving moisture or water; (ii) a conduit between the water collection device and a removal location to which the moisture or water is to be removed, through which there is created a pressure differential to cause the moisture to be pulled into and through the conduit; and (iii) a valve to control passage of moisture or water through the conduit wherein the valve is opened and closed periodically throughout an entire flight duration;
(b) sensing presence of water via one or more water sensors; and
(c) causing the water collected from the water collection device to be directed to the removal location.

23. The method of claim 22 , wherein the removal location comprises an aircraft drain mast, a filtration system, an aircraft grey water flush system, an aircraft humidifier system, an aircraft waste tank, or any combination thereof.

24. The method of claim 22 , wherein the water management system further comprises a control system that directs collected water to the removal location.
