How to Use HVAC UV Light Benefits to Reduce Disease Transmission

HVAC systems can be a blessing or a curse when it comes to disease transmission and infection control. In fact, according to ASHRAE, the transmission of infectious airborne diseases such as tuberculosis, influenza and the common cold can be accelerated or controlled by a building’s HVAC equipment."

The Science Behind UV-C Energy: UV in HVAC Systems

In a recent three-part series of articles published by Consulting Specifying Engineer Magazine, the late Forrest Fencl, co-founder of UV Resources and ASHRAE Fellow, examined how ultraviolet-C (UV-C) energy keeps HVAC equipment operating at peak performance. Part one explained the nature of Ultraviolet Germicidal Irradiation (UV-C) energy.Part two examined UV lamps’ construction and operation(http://www.uvresources.com/blog/the-science-behind-uv-c-energy-how-uv-light-works/)

This third and final piece, looks at HVAC UV light benefits, including how, they can clean cooling coil surfaces, drain pans, air filters and ducts to attain and maintain “as-built” conditions and indoor air quality.

The Science Behind UV-C Energy: What is it?

The Science Behind UV-C Energy: What is it?

Ultraviolet Germicidal Irradiation, or light in the UV-C wavelength (254nm), has been used extensively in HVAC/R equipment since the mid-1990s to boost cooling capacity, lower maintenance costs and save energy. UV-C energy also helps to improve indoor air quality (IAQ) by eliminating the buildup of biofilms and other organic contaminants on the surfaces of system components, including cooling coils, plenum interiors, drain pans and air filters.

In a recent three-part series of articles published by Consulting Specifying Engineer Magazine, the late Forrest Fencl, co-founder of UV Resources and ASHRAE Fellow, examined how UV-C energy keeps HVAC equipment operating at peak performance. The blog explores the first of the three articles: What is UV-C?

Although UV-C is a relatively simple technology, many engineers, building owners and other facility professionals doubt the ability of a simple blue light to increase heat-transfer efficiency, improve IAQ, reduce maintenance and lower energy consumption. Some are mystified about how UV-C can accomplish these feats and how to apply it cost effectively. Since we know of no other HVAC/R technology as effective as UV-C, we felt it crucial to explain what UV-C is and how exactly it works.
