UV Lamps
One of the most significant issues for today’s HVAC (Heating, Ventilation, and Air Conditioning) engineer is Indoor Air Quality (IAQ). Many building owners, operators, and occupants complain of foul odors emanating from HVAC systems.
When it comes to home comfort, UV lamps can make all the difference!
The objectionable odor is the byproduct of the microbial growth (mold and fungus) that accumulates and develops on wet surfaces of HVAC units, causing foul odors to emanate from affected systems and degrading the IAQ and unit performance. Ultraviolet-C (UV-C) is one form of electromagnetic energy produced naturally by the sun. Artificially produced UV-C energy aids in enhancing Indoor Air Quality (IAQ) by eliminating microbial organisms that grow on wet surfaces of HVAC systems.
Solar energy that reaches the earth’s atmosphere interacts with the molecules in the atmosphere by the processes of absorption and scattering. In the process of absorption, molecules absorb the solar energy and convert it to heat. In the scattering process, solar energy is reflected by gas molecules, dust particles, and water vapor. Fortunately the solution is simple. Utilize ultraviolet germicidal irradiation (UVGI) to kill contaminants in the HVAC system. Install man-made sources of UV-C energy in the HVAC system to help eliminate a “source”, and the IAQ three-legged stool collapses.
