For years, UV-C users and manufactures have shared anecdotal experiences and case studies of successful installations of UV-C systems where the result was a clean cooling coil and reduced energy use. Now an ASHRAE research project results confirms.
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 hesitate to leverage these benefits for their application due to a concern about ozone. While the Ultraviolet spectrum contains four separate wavelengths—UV-A, B, C and Vacuum UV—each operates at different energy levels and only one is capable of producing ozone (Vacuum UV).
Biofilm is the greatest enemy of an efficient HVACR system. When biofilm gains a foothold in the coils of your air handler, a slew of operational and efficiency issues will lower performance and drive up costs. This is why it is important to have a routine maintenance program designed to keep coils operating at peak efficiency.
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 year. Ultraviolet germicidal (UV-C) lamps can be a great tool to help you achieve these goals.
Summer is finally here. Three months of warm, sunny days, ice cold beverages and microbial proliferation await you.
That’s right. One negative side effect of the warm weather is humidity. As you know, HVAC systems perform their “cooling” operation by removing heat and moisture from the air. When humidity levels are excessive, they need to work a lot harder.
