UVGI-IAQ Modeling Design Tools(ST10901-1)

Mount Sinai School of Medicine

Background

Over 70 years of upper-room ultraviolet germicidal irradiation (UVGI) applications to reduce person-to-person transmission of airborne respiratory pathogens have produced broad and satisfactory evidence of human safety and efficacy. The time has come to devise a functional method to plan installations in existing rooms, to ensure the effective dose of germicidal irradiation. To develop this method, a computer-aided design (CAD) tool has been used to calculate the 3D UVGI fields generated by multiple fixtures placed in an upper room. The CAD UVGI tool cannot, however, consider the complex air currents that lift pathogens into the UVGI field. A computational fluid dynamics (CFD) simulation tool could be used to model these air currents and the residence time for airborne pathogens in the UVGI field, which defines the amount of UV radiation that the pathogen receives. This statement of work devises CFD advances.

Project Description

Mount Sinai School of Medicine will develop a CFD tool that can assist practitioners in the design and installation of UVGI air-cleansing technologies. Using previously collected upper-room UVGI performance data, CFD simulations of upper-room airflows shall be conducted. Laboratory performance evaluations of UVGI products in test chambers shall be conducted, as well. The measurements from these laboratory evaluations shall be used to validate a CFD-UVGI model.

Benefits

UVGI air cleaners have approximately one-third the operating energy cost of high-efficiency air filters due to their lower-pressure drop in duct systems. Project benefits will be based on technical articles and dissemination of the developed tool to indoor air-quality and CFD practitioners.
