Abstract
Abstract Wall means defines an enclosed air-conditioning space and is connected to ground potential. At least one electrode is carried by the wall means electrically insulated therefrom and is connected to a positive potential so that an electrostatic field is established between the electrode and the wall means. Further there is provided means operative for maintaining the relative humidity of the air in the enclosed space at a substantially constant level.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
194 words
In an arrangemenT for electrostatic environmental conditioning, a combination comprising wall means defining an enclosed air-containing space habitable for human beings and bounded by a plurality of peripheral wall portions connected to ground potential; at least one electrode carried by one of said wall portions electrically insulated therefrom and being connected to a positive potential so that an electrostatic field of predetermined strength is established between said electrode and said wall portions in said enclosed space; and means operative for maintaining the relative humidity of the air in said electrostatic field at a substantially constant level and for thereby preventing changes in said predetermined strength of said electrostatic field due to changes in said level of relative humidity, said means comprising a humidity measuring device located in said space within said electrostatic field and operative for measuring the relative humidity of the ambient air, and an atomizing device operatively associated with said humidity measuring device and responsive to measurements of the same for atomizing water, imparting to it an electric charge, and introducing the atomized charged water into the air in said space in quantities controlled by the measurements of said humidity measuring device.

Claim 3
Dependent Claim
25 words
In an arrangement as defined in claim 1; further comprising additional means operative for maintaining the interior of said enclosed space at substantially constant temperature.
Claim 4
Dependent Claim
34 words
In an arrangement as defined in claim 1, said atomizing device being operative for maintaining the relative humidity of the air in said enclosed space at a level between substantially 40 and 60 percent.
Claim 5
Dependent Claim
48 words
In an arrangement as defined in claim 1, said wall means consisting at least in part of material having hygroscopic properties so selected as to have at said level of relative humidity a constant electrical surface conductivity which is greater than that of the air in said space.
Claim 6
Dependent Claim
