UV-C Lamps - Energy Savings
UV-C Lamps - Energy Savings
(OP)
Has anyone done a calculation on energy savings from installation of UVC lamps in AHUs?
Mainly concerned with SP on a clean coil vs mold-fouled.
Can someone please direct me to a reputable study on mold-related coil fouling, perhaps?
Thanks.

RE: UV-C Lamps - Energy Savings
Fouled coil increases pressure drop. Increased pressure drop reduces air flow. Reduced airflow reduces the necessary fan power.
Then of course the lights use energy.
So clean coil + UV light must use more energy than fouled coil without light.

In any given condition, fan VFDs will deliver the same CFM.

I can't tell if MintJulep is being sarcastic or not...but there are savings in a VAV system that will speed up the fan to compensate for increased pressure drop through the coil that is fouled.

For anyone interested, I found this study. It does not cover mold growth, only debris. But is still an interesting read.
