Abstract
A method for the prevention of zooglea growth within an air conditioning system includes applying an antifouling coating to an interior of a condensate pipe of the air conditioning system, where the antifouling coating has a base layer of an algaecide, an intermediate layer of a hydrophobic polymer, and a top layer of a metallic powder. The method of applying the antifouling coating includes pouring the algaecide coating into the condensate pipe, spinning the condensate pipe, and drying the algaecide coating. The method also includes pouring the hydrophobic polymer into the condensate pipe, spinning the condensate pipe to apply the hydrophobic polymer over the algaecide coating, partially drying the hydrophobic polymer, and pouring the metallic powder into the condensate pipe. In addition, the method includes spinning the condensate pipe to apply the metallic powder over the hydrophobic polymer, and drying the hydrophobic polymer until the metallic powder is embedded.
