Rightsizing UV-C Lamps for HVAC Applications

ASHRAE Handbook—HVAC Applications provides a quantitative approach to UV-C-lamp sizing. This article summarizes that guidance and offers a method to simplify future designs.

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 resistanc
