  • Method and apparatus for cleaning air handling systems
    Publication number: 20030056812
    Abstract: An air handling system is equipped with a system for cleaning the air handling evaporator core in situ. Water is distributed through an intake manifold consisting of a plurality valve or other flow control device. Here, the water picks up treating agents, such as microbicides and cleaning agents. In one of the valves or other flow control devices, the water does not pick up a treating agent, and is used for rinsing. The treated or untreated water flows through a connector to an outlet manifold for contact with an evaporator core of an air handler.
