Abstract

A steam dispersion system for building humidification is disclosed. At least a portion of the steam dispersion system is comprised of a flexible material that is collapsible for changing the outer dimension of the portion comprised of the flexible material from a greater, higher-pressure, size, to a smaller, lower-pressure, size.

Claims (10)

1. A steam dispersion system for building humidification, the steam dispersion system comprising:

a steam header configured to receive humidification steam from a steam source and a plurality of steam dispersion tubes extending from the steam header, wherein the steam header and the plurality of steam dispersion tubes are configured to be mounted in an air duct, the steam header defining a header interior, the steam dispersion tubes defining tube interiors in direct fluid communication with the header interior such that humidification steam flows through the header interior to the tube interiors and exits the tube interiors through steam delivery points, each of the plurality of steam dispersion tubes defining at least a portion comprised of a flexible material that is collapsible for changing the outer dimension of the portion comprised of the flexible material from a greater, higher-pressure size to a smaller, lower-pressure size when the humidification steam is not flowing through the tube interior, wherein the flexible material is permeable to steam so as to define the steam delivery points for delivering the humidification steam into the air duct, wherein the flexible material is a fabric material.

2. A steam dispersion system according to claim 1 , wherein the flexible material is a metallic material.

3. A steam dispersion system according to claim 1 , wherein the flexible material is a non-metallic material.

4. A steam dispersion system according to claim 3 , wherein the non-metallic material is a polymeric material.

5. A steam dispersion system for building humidification, the steam dispersion system comprising:

at least one steam dispersion tube for delivering humidification steam from a steam source to an air duct through a plurality of steam delivery points of the tube, the at least one steam dispersion tube defining at least a portion comprised of a flexible material that is collapsible for changing the portion comprised of the flexible material from a greater, higher-pressure size to a smaller, lower-pressure size when the humidification steam is not flowing through the steam dispersion tube, wherein the flexible material is permeable to steam so as to define the steam delivery points for delivering the humidification steam into the air duct, wherein the flexible material is a fabric material.

6. A steam dispersion system according to claim 5 , wherein the flexible material is a metallic material.

7. A steam dispersion system according to claim 5 , wherein the flexible material is a non-metallic material.

8. A steam dispersion system according to claim 7 , wherein the non-metallic material is a polymeric material.
