Abstract

A mechanical control apparatus is provided for controlling the spray or misting of water into the immediate vicinity of the condenser coils in the compressor unit of an air conditioner, and comprises a hinged, vaned paddle member; and a water valve mechanically connected to and operable by the paddle member. The paddle member is mounted so that blown air flow from an air fan in the compressor unit will impinge on the paddle member, will and cause it to pivot upwardly about a hinge. The paddle member has a mechanical valve operating member, and is connected to a source of pressurized water, so that when the valve is open, water will pass through it to at least one nozzle mounted on the compressor unit to be sprayed or misted into the immediate vicinity of the condenser coils. The mechanical linkage between the paddle member and the valve is such that when the paddle member is pivoted upwardly, the valve will be opened; and when the paddle member is in its horizontal orientation, the valve will be closed. The hinged paddle member has a first half region which is distal with respect to the hinge, and a second half region which is proximal the hinge; and there are a plurality of vane elements which are spaced away from each other. The vane elements which are in the first half region are each sloped upwardly and in a direction towards the hinge, and the vane elements which are in the second half region are each sloped upwardly and in a direction away from the hinge.
