Field: Thermal processes and apparatus (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 7:
8. A cooling tower system comprising:
a cooling tower comprising:
an evaporative heat exchanger, the cooling tower operable to distribute an evaporative liquid onto the evaporative heat exchanger;
a sensor configured to detect a parameter of the evaporative liquid; and
an evaporative liquid treatment system;

a controller operably coupled to the cooling tower, the controller having a normal operating mode wherein the controller operates the evaporative liquid treatment system to treat the evaporative liquid upon a determination of inadequate evaporative liquid quality based at least in part on the parameter of the evaporative liquid; and
the controller having a failsafe operating mode wherein the controller changes operation of the cooling tower upon a determination that the operation of the evaporative liquid treatment system is unable to remedy the inadequate evaporative liquid quality;
wherein the sensor includes at least one of a conductivity sensor, a biofilm sensor, and a pH sensor;
wherein the parameter includes at least one of a conductivity parameter, a biofilm parameter, and a pH parameter; and
wherein the controller, in the failsafe operating mode, is configured to bypass consideration of the at least one of the conductivity parameter, biofilm parameter, and pH parameter.
