Abstract
A system for automatic disinfection and/or aromatization of an HVAC system having a reservoir for holding disinfection or aromatization fluid, an airflow sensor, a pump, an injection apparatus and control module. The airflow sensor and injection apparatus are configured to be coupled to an HVAC duct. The control module is configured to compute the mass of air flowing through such a duct, deliver fluid from the reservoir to the injection apparatus, and to control the injection apparatus so as to inject a quantity of fluid into the duct that is a function of the computed mass of air flowing through the duct.
