What Does Your Liver Have in Common With Your Air-Handling Unit?

摘要

Unfortunately, an air-handling unit (AHU) can't turn its head and cough or let you know when it is sick. Just as your hands need washing to help prevent infection, an AHU coil requires cleaning too. Proper AHU air filtration provides a protective barrier to the internal components and ductwork system in a manner similar to how our livers and kidneys filter out the body's toxins to protect the heart and lungs. A sick AHU also can infect the occupants of the space it serves and use more energy. Filters, therefore, should be checked and replaced and the coil cleaned regularly to maintain good AHU health.
