Ultraviolet Light in HVAC Systems

Posted by: Robert Cave on Tuesday, March 15, 2016

Ultraviolet (UV) light has been growing as part of the HVAC landscape for years, specifically within the indoor air quality (IAQ) arena. As the technology has evolved, organizations and associations have strived to prove its effectiveness through research and a series of studies.

The American Society for Heating, Refrigeration and Air Conditioning Engineers ASHRAE, recently weighed in on the benefits of UV light by “recognizing the health benefits of UV-C as demonstrated by several studies. The technology is a potentially beneficial option that building owners should consider installing.”  This ASHRAE research will dispel any doubts about the ability of Ultraviolet light to improve IAQ, boost HVAC airflow, and maximize heat-exchange efficiency,”

Germicidal UV light has come a long way from its beginnings as a little-known disinfection technology that could be used in HVAC applications.  Since 2008, ASHRAE has included ultraviolet germicidal irradiation, or UVGI, in its handbooks and awareness within the engineering community has resulted in a growing demand for UV in virtually every stage of construction,”

UV technology is one of the most reliable and efficient means of keeping indoor air clean and germ-free. Add to this the savings that can be realized with UV-C’s ability to clean and maintain cooling coil energy efficiency, and we would expect UV applications to significantly increase in the coming years.
