Overview
In today’s complex buildings it is imperative that the HVAC engineer have a basic knowledge of all of the options available to provide an environment suitable to the concerns of the building owner and occupants. These include comfort, indoor air quality, terrorist attacks through the ventilation system, etc. Ultraviolet (UV) lights have been used to disinfect room air streams as far back as 1900 but have become more and more popular due to the recent realization that UV can be effective against infectious diseases and some potential terrorist chemical attacks.
In this course the student will learn some of the basic issues related to UV disinfecting in air ductwork, including the installation parameters that impact the effectiveness of UV lights in air ductwork and considerations regarding the effectiveness of UV lights with respect to germicidal irradiation to deactivate viruses, mycloplasma, bacteria and fungi.
The student is expected to read and review the material contained in "Defining The Effectiveness Of UV Lamps Installed In Circulating Air Ductwork", ARTI-21CR/610-40030-01-November 2002 published by the US Department of Commerce, National Technical Information Service, 5285 Port Royal Road, Springfield, VA 22161 (703-487-4650).
The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to obtain PDH credits.
