Abstract
Abstract A dehumidification system. The dehumidification system utilizes the deflection of high velocity air flow to facilitate the removal of condensate from the cooling coil in the system. The amount of condensate which is reclaimed by the air stream passing through the dehumidification system is minimized.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
180 words
A dehumidifier, including the (a) coil means for cooling air passing over said coil means and causing water to condense from the air onto the coil means, said coil means including (i) a first entrance side, air flowing toward said entrance side to pass over said coil means and be cooled and condense water onto said coil means, and (ii) a second exit side spaced away from said entrance side, cooled air flowing in a selected direction of travel away from said second side and said coil means; (b) air deflection means shaped and dimensioned to deflect cooled air from said selected direction of travel such that said deflected air generates forces acting on at least a portion of said condensed water on said coil means to assist in moving said water over said coil means; and, (c) means for imparting motive force to air such that said air flows toward said entrance side, over said coil means, away from said exit side, and is deflected by said deflection means to assist in moving said water over said coil means.
Claim 2
Dependent Claim
180 words
A dehumidifier, including the (a) coil means for cooling air passing over said coil means and causing water to condense from the air onto the coil means, said coil means including (i) a first entrance side, air flowing toward said entrance side to pass over said coil means and be cooled and condense water onto said coil means, and (ii) a second exit side spaced away from said entrance side, cooled air flowing in a selected direction of travel away from said second side and said coil means; (b) air deflection means shaped and dimensioned to deflect cooled air from said selected direction of travel such that said deflected air generates forces acting on at least a portion of said condensed water on said coil means to assist in moving said water over said coil means; and, (c) means for imparting motive force to air such that said air flows toward said entrance side, over said coil means, away from said exit side, and is deflected by said deflection means to assist in moving said water over said coil means.
Claim 3
Dependent Claim
49 words
The dehumidifier of claim 1 wherein said motive force imparting means includes pulling means for generating static pressure in the range of 0.5 to 3.0 inches of water to pull air from said first side, over said coil means, and away from said exit side toward said pulling means.
Claim 4
Dependent Claim
85 words
The dehumidifier of claim 2 including (a) tray means positioned beneath said coil means for collecting condensed water moving toward and into said tray means; and, (b) a sloped surface positioned above collected water in said tray means, at least a portion of said condensed water from said coil means contacting and traveling (i) down said sloped surface in a direction away from said entrance side and from at least a portion of said coil means, and (ii) into water collected in said tray means.
Claim 5
Dependent Claim
85 words
The dehumidifier of claim 1 including (a) tray means positioned beneath said coil means for collecting condensed water moving toward and into said tray means; and, (b) a sloped surface positioned above collected water in said tray means, at least a portion of said condensed water from said coil means contacting and traveling (i) down said sloped surface in a direction away from said entrance side and from at least a portion of said coil means, and (ii) into water collected in said tray means.
Claim 6
Dependent Claim
49 words
The dehumidifier of claim 4 wherein said motive force imparting means includes pulling means for generating static pressure in the range of 0.5 to 3.0 inches of water to pull air from said first side, over said coil means, and away from said exit side toward said pulling means.
Claim 7
Dependent Claim
25 words
The dehumidifier of claim 1 wherein said coil means is cooled by a refrigerant flowing through said coil means at a selected adjustable flow rate.
Claim 8
Dependent Claim
43 words
The dehumidifier of claim 6 including valve means for adjusting said flow rate of said refrigerant through said coil means, said valve means being responsive to the temperature of said refrigerant to adjust said flow rate of said refrigerant through said coil means.
Claim 9
Dependent Claim
52 words
The dehumidifier of claim 7 including (a) means for delivering cooled refrigerant to said coil means to flow therethrough and absorb heat from air flowing over said coil means, and, (b) means for receiving refrigerant which has flowed through said coil means and absorbed heat from air flowing over said coil means.
Claim 10
Dependent Claim
33 words
The dehumidifier of claim 8 wherein the temperature of said cooled refrigerant is 1° F. to 3° F. less than the temperature of refrigerant received from said coil means by said receiving means.
