Abstract:
A method of treatment of air conditioning systems of the kind comprising an air flow-producing device; and an air cooling device positioned in a path of air flow from said air flow-producing device; said method comprising the steps of:a) applying a microbial control treatment medium to air contacting surfaces of said air cooling device, said step of applying said microbial control treatment medium comprising the step of providing an air treatment element positioned in a path of an in flow of air to said air cooling device and said air treatment element comprising a supply of said microbial control treatment medium and a supply of an entrainment medium therefor adapted to enable said microbial control treatment medium to be entrained therewith in the air flow produced by said air flow-producing device; b) causing said air-flow producing means to entrain said microbial control treatment medium with the entrainment medium from said air treatment element in said air flow; and c) causing said air cooling device to cool said air flow to cause at least some of said entrained microbial control medium to be condensed and removed from said air flow onto cooled surfaces of said air cooling device.
