ABSTRACT:
The disclosure pertains to a method and apparatus for controlling microbial growth in air handling systems employing heat exchanging coils, water pans, or the like, exposed to moisture and subject to microbial contamination. Condensation apparatus located within a chamber defined in an air handling system is disinfected by temporarily interrupting normal air flow, sealing the chamber with respect to the air handling system, introducing an anti-microbial growth gaseous disinfectant into the chamber, removing the anti-microbial gas from the chamber after disinfecting the condensation apparatus and then restoring normal air flow through the chamber. The preferred anti-microbial gas is produced by using an ozone generator in conjunction with an auxiliary air flow system.
