Patent ID: 8074461

Claim:
A pre-cooling system for use with a water source and a condenser unit of an air conditioner, the condenser unit producing an exhaust ejected in a substantially vertical direction, the pre-cooling system comprising: a housing coupleable to the condenser; a valve mounted to the housing and coupleable to the water source, the valve traverseable between an open position for permitting water to flow through the valve and a closed position for preventing water from flowing through the valve; an aerodynamic vane defining a pivot end portion with an abutment shoulder, the aerodynamic vane being pivotable about the pivot end portion between a raised position and a down position, the abutment shoulder of the pivot end portion of the aerodynamic vane directly contacting the valve to traverse the valve to the closed position when the aerodynamic vane is pivoted to the down position, the aerodynamic vane disposable within the vertically directed exhaust for creating a drag force, the vane having an uppersurface and an undersurface, the uppersurface having a length longer than the undersurface for creating a lift force in response to the vertically directed exhaust passing over the aerodynamic vane, the lift force characterized by a pressure differential between a first pressure adjacent the uppersurface and a second pressure adjacent the undersurface created in response to exhaust passing over the vane, the first pressure being less than the second pressure, the vane being pivoted toward the raised position to traverse the valve to the open position by the lift force and the drag force when the vertically directed exhaust passes over the vane, the vane being pivoted toward the down position to traverse the valve to the closed position by eliminating the lift force and the drag force when the condenser unit does not produce the vertically directed exhaust.
