Ultraviolet Lighting Applications in HVAC Systems

It is generally agreed that source removal of contaminants remains the single best method for cleaning and decontaminating HVAC systems. One of the tools used to improve air quality from HVAC systems is the use of ultraviolet lighting within the system, intended to decrease the level of airborne pathogens and allergens going through the HVAC system and thus into the indoor air environment. Currently a broad range of information exists regarding the use and efficacy of ultraviolet lighting. This paper provides direction in the use of ultraviolet lighting applications in HVAC systems.

Ozone Applications in HVAC Systems

Source removal of contaminants remains the single best method for cleaning and decontaminating HVAC systems. However, HVAC systems sometimes require treatment for odors or the reduction of microbial contamination. One remedy that has been used for these problems is ozone, a form of oxygen. Currently a broad range of information exists regarding the use and efficacy of ozone. This paper provides direction in the use of ozone applications in HVAC systems.
