Air conditioner condensation pan overflow protection

Abstract

A liquid level sensor ( 100 ) is added to air conditioner condensation pan(s) ( 40 and/or 50 ) to prevent overflow and subsequent house damage by turning off the compressor ( 80 ) and the fan ( 20 ) by means of a circuit breaker ( 120 ) and associated electronics ( 110 ).

1 . A method for preventing the overflow of refrigeration air conditioner condensation pan(s), comprising: 
 a) a liquid level sensor in the pan or pans, and    b) sensor electronic circuitry to activate the sensor, and    c) a connection between the sensor circuitry and circuit breakers in the air conditioner compressor and fan power lines, and    d) a connection between the sensor circuitry and an alarm,    whereby a rise in the level of condensed water in the pan or pans to a point near spillage will turn off the compressor and fan, and activate an alarm.    
     
     
         2 . The liquid level sensor and associated circuitry of  claim 1 , used to prevent the overflow of the drain pan on evaporative air conditioners by shutting off the water pump and activating an alarm.
