Light in the Ultraviolet-C (UV-C) spectrum has proven effective in killing virtually all known microorganisms, making it the ideal solution for cleaning HVAC cooling coils and decontaminating the upper air in public spaces such as schools and hospitals. However, the potency of UV lamps means...
Airborne infectious diseases can run rampant in facilities, such as schools and hospitals, if not properly combated. Frequent hand washing and covering one’s nose while sneezing can only go so far, unfortunately, beckoning for a more systematic method of improving indoor environmental quality (IEQ). In...
Roughly 55 million students and seven million staff attend the 130,000 public and private schools each day in the United States. At any given time, each of those people are susceptible to various types of illness, many of which are communicated through the air. Ironically,...
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...
Clean air is not only good for your lungs, but also for your brain, according to new research from the Harvard T.H. Chan School of Public Health's Center for Health and the Global Environment. To help conserve energy, building engineers have made significant progress over...
UV-C systems provide three levels of benefits when applied to HVAC systems.UV-C energy eliminates and/or prevents the buildup of organic material on the surfaces of cooling coils, drain pans, and interior duct surfaces. This improves airflow, returns and maintains the heat-transfer levels of cooling coils...
Modern UV lighting for HVAC systems resembles fluorescent lamps typically found in commercial office buildings. Both types of lamps have similar form and operate using identical electrochemical processes: an electric discharge through argon gas strikes mercury vapor to generate a photon with a wavelength of...
UV light comprises a segment of the electromagnetic spectrum between 400 and 100 nm, corresponding to photon energies from 3 to 124 eV. The UV segment has four sections, labeled UV-A (400 to 315 nm), UV-B (315 to 280 nm), very high energy and destructive...
