Abstract
Abstract In an installation comprising a plurality of hermetically sealed multiple glazed window units, all of the window units are ducted to a common manifold. The manifold is ported to the atmosphere through pressure-compensating apparatus which vents air pressure built up within the system into the atmosphere, and admits filtered, dehumidified air drawn from the atmosphere into the system when ambient atmospheric air pressure exceeds the internal air pressure within the system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
255 words
In a window installation of a type including at least one window unit mounted in a wall of a building defining a substantially enclosed volume, the interior atmosphere of said enclosed volume being substantially controlled to remain within a predetermined range of temperatures, the pressure within said enclosed volume often being affected by factors additional to the atmospheric pressure exterior of said enclosed volume and therefore normally being different therefrom, and the atmosphere exterior of said enclosed volume being substantially uncontrolled and therefore variable in temperature and pressure in correspondence With prevailing outdoor temperature and pressure, each said window unit comprising a window frame sealingly mounting a plurality of laterally spaced window panes defining a sealed interior window volume therebetween, a surface of one of said plurality of panes being exposed to said atmosphere exterior of said enclosed volume and a surface of another of said plurality of panes being exposed to said atmosphere interior of said enclosed volume, a system for removing moisture from within said interior window volume and for maintaining each said window unit substantially free from visual distortion as viewed from the exterior of said enclosed volume, said system comprising: a hygroscopic material first air passage means providing communication between said otherwise sealed interior window volume and said hygroscopic material, and second air passage means providing continuous communication between said hygroscopic material and a relatively unconfined volume, as compared to said interior window volume, in which the atmospheric pressure substantially corresponds with the atmospheric pressure prevailing exteriorally of said enclosed volume.
Claim 2
Dependent Claim
255 words
In a window installation of a type including at least one window unit mounted in a wall of a building defining a substantially enclosed volume, the interior atmosphere of said enclosed volume being substantially controlled to remain within a predetermined range of temperatures, the pressure within said enclosed volume often being affected by factors additional to the atmospheric pressure exterior of said enclosed volume and therefore normally being different therefrom, and the atmosphere exterior of said enclosed volume being substantially uncontrolled and therefore variable in temperature and pressure in correspondence With prevailing outdoor temperature and pressure, each said window unit comprising a window frame sealingly mounting a plurality of laterally spaced window panes defining a sealed interior window volume therebetween, a surface of one of said plurality of panes being exposed to said atmosphere exterior of said enclosed volume and a surface of another of said plurality of panes being exposed to said atmosphere interior of said enclosed volume, a system for removing moisture from within said interior window volume and for maintaining each said window unit substantially free from visual distortion as viewed from the exterior of said enclosed volume, said system comprising: a hygroscopic material first air passage means providing communication between said otherwise sealed interior window volume and said hygroscopic material, and second air passage means providing continuous communication between said hygroscopic material and a relatively unconfined volume, as compared to said interior window volume, in which the atmospheric pressure substantially corresponds with the atmospheric pressure prevailing exteriorally of said enclosed volume.
Claim 3
Dependent Claim
35 words
The system of claim 1 further comprising a plurality of means containing said hygroscopic material, and means for providing constant communication between said first air passage means and one of said plurality of containing means.
Claim 4
Dependent Claim
41 words
The system of claim 1 wherein said system further comprises means for selectively purging moisture from a first portion of said hygroscopic material while providing continuous communication between said first air passage means and a second portion of said hygroscopic material.
Claim 5
Dependent Claim
59 words
The system of claim 3 including a plurality of windows as described therein, and manifold means providing continuous communication between each said otherwise sealed space in each of said plurality of windows with each said otherwise sealed space in every other of said plurality of windows and with said relatively unconfined volume through said air drying and cleaning means.
Claim 6
Dependent Claim
185 words
An air breathing system for use with multipaned windows mounted in a building enclosure wall with the exterior surface of a first pane exposed to the building exterior whereat atmospheric temperature and pressure are substantially uncontrolled and therefore vary in correspondence with the prevailing outdoor temperature and pressure, and with the exterior surface of a second pane exposed to the building interior whereat atmospheric temperature is controlled to remain within a predetermined range and the atmospheric pressure is often affected by factors additional to the atmospheric pressure at the exterior of the building enclosure wall and is therefore normally different therefrom, said system comprising: air drying and cleaning means, at least one multipaned window mounted otherwise in the building exterior wall and having a sealed space intermediate the panes thereof, a relatively unconfined volume, compared to said sealed space, having a pressure which varies in correspondence with that prevailing on the exterior of the building wall in which said window is mounted, and means providing continuous communication between said other wise sealed space and said relatively unconfined volume through said air drying and cleaning means.
Claim 7
Dependent Claim
185 words
An air breathing system for use with multipaned windows mounted in a building enclosure wall with the exterior surface of a first pane exposed to the building exterior whereat atmospheric temperature and pressure are substantially uncontrolled and therefore vary in correspondence with the prevailing outdoor temperature and pressure, and with the exterior surface of a second pane exposed to the building interior whereat atmospheric temperature is controlled to remain within a predetermined range and the atmospheric pressure is often affected by factors additional to the atmospheric pressure at the exterior of the building enclosure wall and is therefore normally different therefrom, said system comprising: air drying and cleaning means, at least one multipaned window mounted otherwise in the building exterior wall and having a sealed space intermediate the panes thereof, a relatively unconfined volume, compared to said sealed space, having a pressure which varies in correspondence with that prevailing on the exterior of the building wall in which said window is mounted, and means providing continuous communication between said other wise sealed space and said relatively unconfined volume through said air drying and cleaning means.
Claim 8
Dependent Claim
38 words
The system of claim 5 including means for selectively purging moisture from said air drying and cleaning means while maintaining communication between said otherwise sealed space and said relatively unconfined volume through said air drying and cleaning means.
