The Ultraviolet Germicidal Irradiation (UV-C) wavelength is an invaluable tool for an HVACR system. By leveraging germicidal energy to keep refrigeration coils free of microbial growth, facility managers also enjoy the benefit of reducing the spread of airborne infectious agents. However, some facility managers may...
School is back in session and cold and flu season isn’t far behind. If you’re a facility manager at a school, university or some other educational facility, you are looking to your HVAC/R system to maintain indoor air quality and efficient operation throughout the upcoming...
When people first see the futuristic blue hue of an ultravioet-c (UV-C) lamp, some might think ultraviolet germicidal irradiation (UVGI) is a recent invention. Yet, knowledge of UV-C goes back well over 100 years, having gone through various phases of development. Here’s a brief history...
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...
Many factors can impact a building’s environmental performance and the consumption of energy, water and materials. Manufacturers of building systems design performance around a specific, optimal condition. Over time, these performance standards will deteriorate if nothing is done to preserve the original “as-built” condition. This...
ASHRAE recently released two position documents (links listed below) examining the health consequences of using filtration and air cleaning technologies in HVAC systems. Our own Dean Saputa is an active member of one of the committees responsible for this research (the ASHRAE Filtration and Air...
We are in the midst of an HVAC revolution as the number of mechanical engineers specifying UV-C in all building types is mushrooming at historic levels.The ultraviolet-C (UV-C) wavelength (254nm) was promoted in the mid-1990s primarily to improve indoor air quality by preventing microbial buildup...
UV-C rips apart elemental bonds in organic matter, degrading them similarly to how UV light from the sun degrades vinyl and rubber, etc. UV-C eliminates biofilms, mold and fungi, and other organic contaminants on coils, drain pains, and plenum interiors. In new HVAC/R systems where...
