Problems solved by technology

HVAC systems known as mini-split systems present a particularly troublesome challenge.
These air handlers are designed to be compact resulting in limited space for an overflow switch and condensate sensor.
As a result, any electronics that would utilize the power supply has the potential of disrupting the communication link.

Embodiment Construction

[0025]The present invention relates to a system control to monitor and selectively control the operation of an air conditioning system that includes a compressor 10 and an air handler 12 including an evaporator 14.

[0026]As shown in FIG. 1, the air handler 12 and evaporator 14 are coupled in closed-loop fluid communication with the compressor 10 by refrigerant lines or conduits 16 and 18. A condensate collector or drain pan 20 is disposed to collect condensate from the evaporator 14 and a condensate drain 22 can direct or carry condensate from the condensate collector or drain pan 14 to a collection or run-off site (not shown). The air handler 12 further includes an air handler electronic control system 24 coupled to multiple or independent redundant fault sensors or thermistors 26 and 28 disposed in heat exchange relationship relative to the evaporator 14. The compressor 10 and air handler electronic control system 24 are operatively coupled together by power supply line 30 and a da...

Abstract

A system control to monitor and control the operation of an air conditioning system including at least one evaporator / air handler unit operatively coupled to a compressor / condenser unit comprising a sensor to monitor the operation of the evaporator and to generate a control signal when a predetermined condition within the air conditioning system is sensed and a control unit including logic or circuitry to receive the condensate signal and to deactivate the evaporator / air handler unit and the compressor / condenser unit in response to the control signal.

Description

CROSS-REFERENCE[0001]This application claims priority as a continuation-in-part application of patent application Ser. No. 12 / 931,130 filed Jan. 25, 2011 that is a continuation-in-part application of patent application Ser. No. 12 / 806,977 filed Aug. 25, 2010.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]A system control to monitor and selectively control the operation of an air conditioning system.[0004]2. Description of the Prior Art[0005]Air handling systems such as air conditioning systems typically have a condensate collector or drain pan to collect condensate.[0006]Often removal of the condensate requires pumping the condensate from the condensation drain pan. Commonly, a drain pan system includes a sensor placed in the drain pan to measure the level of the condensation therein. When the condensate level reaches a predetermined level, the sensor generates a signal sent to a sensor switching circuit to activate the pump or stop operation of the compressor.[0007...
