Abstract
Systems and methods for electrolytic spa sanitation are provided which control electrodes in a manner that extends the use of electrodes, reducing the frequency of replacement of electrodes. The system also incorporates electrodes that can be easily replaced by a user, further reducing the need to maintenance by trained service personnel. Systems and methods use measurements from ORP, pH, and temperature sensors to determine the amount of sanitizer necessary to be produced from the electrodes. The electrodes are capable or acting as either an anode or a cathode.
Claims18
A method for controlling a spa sanitation system of a water-containing vessel, comprising:
- acquiring Oxidation Reduction Potential (ORP) measurements, pH measurements, and temperature measurements for water in the water-containing vessel;
- determining a voltage and a current to be delivered to two or more electrodes of the spa sanitation system to electrolytically produce a sanitizer;
- determining a time period for which to run the two or more electrodes to electrolytically produce the sanitizer;
- and
- selecting a polarity configuration of the two or more electrodes;
- wherein the polarity configuration comprises at least a first polarity and a second polarity;
- wherein the step of selecting the polarity configuration comprises measuring a first impedance of the two or more electrodes in the first polarity and measuring a second impedance of the two or more electrodes in the second polarity, and selecting the polarity configuration having a lower impedance;
- and
- further comprising switching the polarity configuration based on the first impedance and the second impedance such that the polarity configuration with the lower impedance is used.
A sanitation system for a water-containing vessel, comprising:
- a controller configured to
- acquire Oxidation Reduction Potential (ORP) measurements, pH measurements, and temperature measurements for water in the water-containing vessel;
- determine a voltage and a current to be delivered to two or more electrodes of the sanitation system to electrolytically produce a sanitizer;
- determine a time period for which to run the two or more electrodes to electrolytically produce the sanitizer;
- and
- select a polarity configuration of the two or more electrodes;
- wherein the polarity configuration comprises at least a first polarity and a second polarity;
- wherein when the controller selects the polarity configuration, it measures a first impedance of the two or more electrodes in the first polarity and measures a second impedance of the two or more electrodes in the second polarity, and selects the polarity configuration having a lower impedance;
- and
- wherein the controller is further configured to switch the polarity configuration based on the first impedance and the second impedance such that the polarity configuration with the lower impedance is used.
