Abstract
Abstract A system for cooling the air cooled condenser coils with a water vapor or mist so as to lower the temperature of the coil by evaporation to improve the efficiency of an air conditioning system using air cooled condenser coils. In the present system water is directed through a solenoid valve in a regulated, metered amount to the upper surface of the lower portion of the air conditioner and is thermostatically controlled, which solenoid valve is connected in parallel with the electrical circuit which energizes the compressor motor so the solenoid valve will operate when the compressor motor operates. Further provision is made to supply a radially fluted annular ring to attach to the outer periphery of a blower fan to cause water, in the lower portion of the air conditioner to be vaporized.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
In combination with an air conditioner having an air cooled condenser coil; a. a blower fan having radial blades to direct air through the condenser coil, 1. said radial blades of said fan being apertured near the respective outer ends thereof, b. an annular ring, 1. said ring having radial flutes formed therein, 2. inwardly extending, apertured lugs formed on said annular ring at spaced intervals around the inner diameter thereof so the apertures in said lugs will register with the apertures in said radial blades of said fan, 3. fastening means passing through the apertures to connect said apertured lugs on said ring to the apertured blades of said fan, c. the lower portion of the housing being adapted to entrap water on the surface thereof, d. a conduit leading from a water supply to direCt water onto the upper surface of the lower portion of the housing of the air conditioner, e. a water control metering valve within the said conduit, f. said radial flutes formed on said ring dip into the water in the lower portion of the air conditioner housing to cause the water to be broken into mist, when the fluted ring is rotated, to direct the mist into the air stream leading through said condenser coil.

Claim 3
Dependent Claim
35 words
inwardly extending, apertured lugs formed on said annular ring at spaced intervals around the inner diameter thereof so the apertures in said lugs will register with the apertures in said radial blades of said fan,
Claim 4
Dependent Claim
35 words
inwardly extending, apertured lugs formed on said annular ring at spaced intervals around the inner diameter thereof so the apertures in said lugs will register with the apertures in said radial blades of said fan,
Claim 5
Dependent Claim
37 words
In combination with an air conditioner having an air cooled condenser coil, as defined in claim 1; wherein a. an electric motor in the air conditioner, b. a compressor connected in driven relation with said electric motor,
Claim 6
Dependent Claim
64 words
In combination with an air conditioner having an air cooled coil, as defined in claim 1; wherein a. an apertured link extends between the outer portion of each radial fan blade and the respective apertured lugs on said ring so the apertures in said links will register with the apertures in the respective fan blades and the apertures in the respective inwardly extending lugs,
Claim 7
Dependent Claim
122 words
fastening means passing through the apertures to connect said apertured lugs on said ring to the apertured blades of said fan, c. the lower portion of the housing being adapted to entrap water on the surface thereof, d. a conduit leading from a water supply to direCt water onto the upper surface of the lower portion of the housing of the air conditioner, e. a water control metering valve within the said conduit, f. said radial flutes formed on said ring dip into the water in the lower portion of the air conditioner housing to cause the water to be broken into mist, when the fluted ring is rotated, to direct the mist into the air stream leading through said condenser coil.
