Condenser coil cooling apparatus

Apparatus for cooling the condenser coils of an air conditioner, comprising

• (a) a housing adapted for mounting on the air conditioner;
• (b) a low pressure fluid supply connected with said housing;
• (c) valve means arranged in said housing and connected with said low pressure fluid supply and operable between open and closed positions to deliver and interrupt the flow of fluid from said supply, respectively;
• (d) valve control means arranged in said housing and connected with said valve means for opening and closing said valve means, said valve control means including a vibration transducer which senses vibration of the condenser when the condenser is operating, said transducer producing a first signal in response to initiation of sensed condenser vibration to open said valve means and a second signal in response to termination of sensed condenser vibrations to close said valve means when the condenser is inoperative;
• (e) a self-contained power supply arranged within said housing and connected with said valve control means;
• and
• (f) nozzle means connected with said valve means and arranged adjacent the coils for spraying a fluid mist on the coils when said valve means is in the open position, said fluid mist cooling the condenser coils when the condenser is operating, thereby increasing the efficiency of the condenser.
