Abstract

The invention relates to a method for improving the thermal comfort in passenger planes by means of a heat-reflecting coating with a low thermal emission coefficient, and airplanes and airplane parts bearing this coating. According to the invention, the coating is applied to the existing interior surfaces of the airplane cabin wall such that a passenger of the airplane may be in direct radiation exchange with this coating.

Claims

1. A method of improving thermal comfort in a passenger airplane, the airplane having a cabin with interior surfaces, the airplane cabin for transporting one or more passengers, the method comprising:

applying a heat-reflecting coating with a thermal emission coefficient no greater than approximately 0.5 to at least one interior surface of a cabin of a passenger airplane,

whereby the coating provides improved radiation exchange with a passenger in the airplane cabin when compared with an uncoated interior surface wherein the at least one interior surface of the airplane cabin comprises decorative plastic foil, and wherein the coating is applied to the decorative plastic foil.

2. The method of claim 1, wherein the decorative plastic foil comprises polyvinylfluoride.

3. The method of claim 1, wherein the decorative plastic foil comprises polyvinylidenefluoride.

4. The method of claim 1, wherein the coating is a transparent conductive coating.

5. The method of claim 1, wherein the coating comprises a conductive metal oxide.

6. The method of claim 1, wherein the coating comprising indium tin oxide.

7. The method of claim 1, further comprising selecting a coating thickness to achieve a desired thermal emission coefficient for the coating.

8. The method according to claim 7, wherein the thickness of the coating, as applied, is less than 1 μ

m.

9. The method of claim 1, wherein at least one interior surface of the airplane cabin further comprises at least one window of transparent plastic material, and wherein the coating is applied to the at least one window.

10. The method of claim 9, wherein the at least one window comprises polymethylmethacrylate.

11. The method of claim 9, wherein the at least one window comprises polycarbonate.

12. The method of claim 1, wherein the at least one interior surface of the airplane cabin comprises decorative plastic foil, and wherein the coating is applied to the decorative plastic foil.

13. The method of claim 1, wherein the decorative plastic foil comprises polyvinylfluoride.

14. The method of claim 1, wherein the decorative plastic foil comprises polyvinylidenefluoride.
