Abstract
Abstract This invention relates generally to the cooling of a condenser coil in the outdoor compressor unit of a central air conditioning system by injecting an atomized mist of minute water particles into the upstream side of a stream of air passing through the coil for fogging the coil with the mist for more effective and complete evaporation thereof, cooling the coil more efficiently while reducing the amount of residual runoff water.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
257 words
A fogging device for cooling a condenser coil in a central air condition system having an outdoor compressor unit, a housing for said compressor unit containing a fan, an opening in said housing through which a stream of air is created flowing across said condenser coil carried within said housing adjacent said opening and extending thereover, said condenser coil receiving refrigerant fluid from a compressor motor, said device comprising: a control valve having an inlet port connected to a source of pressurized water; nozzle means connected to an outlet port of said control valve receiving a flow of water from said source when said is in an open position; means for moving said control valve to said open position in response to said compressor motor being energized; and said nozzle means having an opening and orifice formed therein for highly atomizing said water into a mist of finely divided water particles, said nozzle means projecting a metered amount of water in the form of said atomized mist as a fan-shaped curtain across an area substantially coextensive with and adjacent to said housing opening, said curtain of mist being received by said air stream prior to passing across said coil as to be mixed and further atomized therein for fogging and enveloping said condenser coil with said mist; whereby said mist of minute water particles adheres more readily to said coil and is more effectively and completely evaporated by the heat from said condenser coil, cooling said coil more efficiently while reducing the amount of residual runoff water.
Claim 2
Dependent Claim
257 words
A fogging device for cooling a condenser coil in a central air condition system having an outdoor compressor unit, a housing for said compressor unit containing a fan, an opening in said housing through which a stream of air is created flowing across said condenser coil carried within said housing adjacent said opening and extending thereover, said condenser coil receiving refrigerant fluid from a compressor motor, said device comprising: a control valve having an inlet port connected to a source of pressurized water; nozzle means connected to an outlet port of said control valve receiving a flow of water from said source when said is in an open position; means for moving said control valve to said open position in response to said compressor motor being energized; and said nozzle means having an opening and orifice formed therein for highly atomizing said water into a mist of finely divided water particles, said nozzle means projecting a metered amount of water in the form of said atomized mist as a fan-shaped curtain across an area substantially coextensive with and adjacent to said housing opening, said curtain of mist being received by said air stream prior to passing across said coil as to be mixed and further atomized therein for fogging and enveloping said condenser coil with said mist; whereby said mist of minute water particles adheres more readily to said coil and is more effectively and completely evaporated by the heat from said condenser coil, cooling said coil more efficiently while reducing the amount of residual runoff water.
Claim 3
Dependent Claim
39 words
The structure set forth in claim 1 wherein said nozzle means includes a single nozzle positioned by a bracket means for so directing said mist, and wherein said stream of air is drawn by said fan across said coil.
Claim 4
Dependent Claim
40 words
The structure set forth in claim 2 wherein said bracket means and nozzle are positioned above said condenser coil and said stream of air on the upstream side of said condenser coil, said bracket means being carried by said housing.
Claim 5
Dependent Claim
55 words
The structure set forth in claim 1 wherein said nozzle injects the curtain of mist in a plane substantially parallel to said housing opening and condenser coil and substantially perpendicular to said stream of air flow across said coil to shear and further divide the mist particles prior to fogging and enveloping said condenser coil.
Claim 6
Dependent Claim
46 words
The structure set forth in claim 2 wherein said single nozzle includes a transverse groove extending across the width in a bottom surface thereof, and an orifice formed in said groove producing said fan-shaped curtain of mist covering substantially the entire surface of said condenser coil.
Claim 7
Dependent Claim
49 words
The structure set forth in claim 1 wherein a receptacle is connected between said source of pressurized water and said inlet port containing an additive which is mixed with said flow of water so as to reduce the formation of mineral deposits and other accumultors on said condenser coil.
