Over time, organic material can accumulate on HVAC cooling coils, reducing heat-transfer effectiveness.1 Often, system controls and building engineers compensate by increasing fan speed, lowering chilled-water temperature, and even pumping more refrigerant, all at the expense of energy efficiency. Ultraviolet-C (UV-C) energy can be used to irradiate HVAC cooling coils, returning resistance to airflow and heat-transfer efficiency to as-built levels and allowing building engineers to slow fans, add variable-frequency drives, configure chillers to original design parameters, and more. Energy savings of 10 to 30 percent have been reported once coil capacity is restored.(read the article)
