Project Description:
§ Proposes to research the feasibility of using strong pulsating electric fields with inert electrodes directly into the circulating water in water-cooled air conditioning systems to achieve a reduction in mineral and bio fouling in the condenser tubes such that chemical treatment is no longer needed.
Proposed Outcomes:
§ A prototype will be fabricated and tested.
Anticipated Benefits:
§ Potential to significantly reduce environmental damage caused by anti bio-fouling and scale inhibiting chemicals used in 92% of the facilities that have water cooled air conditioning systems.
§ Potential to increase the heat transfer efficiency of cooling towers by 10% over current state of the art physical water treatment methods which could reduce total California energy consumption by 6-9 GWh per year or approximately 2-4%.
