Uv Light In Hvac Effectiveness

The uvgi light operates within the uv c spectrum which is the effective wavelength spectrum for germicidal efficiency.

Uv light in hvac effectiveness.

In most residential cases an hvac company will install the uv light near the coils to prevent mold or bacteria growth as air passes through. The ultraviolet germicidal light uvgi can help eliminate many types of bacteria and viruses. The lights used in hvac systems are uv c lights meaning they operate at the c frequency on the spectrum and is between 200 285 nanometers in size. Since all of the air passes through the coils this also kills growths in the air.

There are a couple different set ups for the uv lights in the hvac system. But only certain uv lights can be used in air purification. Also if your hvac system has damaged or leaky ducts the vacuum created in the ducts could draw in new contaminates from attics and crawl spaces limiting the uv light effectiveness. Ultraviolet lights specifically germicidal uvc.

Uv light penetrates at 254 nanometers wavelength penetrates the nucleus and destroys the nuclei of the mold and bacteria rendering it unable to reproduce and useless. When properly installed and maintained within an hvac system uv lights increase the quality of air in buildings. Shortwave radiation uv c is emitted from these systems and is most effective at killing mold bacteria and viruses. Experts believe that improvements to hvac units and the addition of uv lights at the office or at the home can help in the fight against covid 19.
