Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
61 words
In a condenser having tubing for carrying fluid to be condensed and cooled and a fan for moving ambient air over said tubing, the improvement comprising: a horizontal bed of beads positioned in the path of the air flowing to said tubing; and means for applying water to said bed of beads whereby water vapor will be entrained in said air.
Claim 2
Dependent Claim
61 words
In a condenser having tubing for carrying fluid to be condensed and cooled and a fan for moving ambient air over said tubing, the improvement comprising: a horizontal bed of beads positioned in the path of the air flowing to said tubing; and means for applying water to said bed of beads whereby water vapor will be entrained in said air.
Claim 3
Dependent Claim
22 words
A condenser in accordance with claim 1 wherein: said bed of beads is maintained in place by upper and lower foraminated walls.
Claim 4
Dependent Claim
21 words
A condenser in accordance with claim 1 wherein: said means for applying water to said bed of beads includes spray nozzle.
Claim 5
Dependent Claim
12 words
A condenser in accordance with claim 1 wherein: said tubing is finned.
Claim 6
Dependent Claim
42 words
A condenser in accordance with claim 1 wherein: said tubing is contained in an annular cavity formed by spaced inner and outer walls of said condenser and said bed of beads is located in the cylindrical passage formed by said inner walls.
Claim 7
Dependent Claim
24 words
A condenser in accordance with claim 5 further including: baffle means located above said cylindrical passage for directing air flow into said annular cavity.
Claim 8
Independent Claim
55 words
A method of cooling fluid contained in the tubing of a condenser comprising: applying water to a bed of beads; passing air first through said bed of beads and then over said tubing; and periodically terminating the application of water to said bed of beads long enough to dry said beads and fluidize said bed.
Claim 9
Independent Claim
55 words
A method of cooling fluid contained in the tubing of a condenser comprising: applying water to a bed of beads; passing air first through said bed of beads and then over said tubing; and periodically terminating the application of water to said bed of beads long enough to dry said beads and fluidize said bed.
