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).
Claims2
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.
