Title

(EN) METHOD AND SYSTEM FOR ULTRAVIOLET GERMICIDAL IRRADIATION SIMULATION

(FR) PROCÉDÉ ET SYSTÈME DE SIMULATION D'IRRADIATION GERMICIDE AUX ULTRAVIOLETS

Abstract

(EN) Herein is disclosed a method for simulating ultraviolet germicidal irradiation (UVGI) of a subject microbe in a room, the method comprising: generating a 3D model of the room; receiving irradiance data associated with the UVGI source; receiving a base susceptibility for the subject microbe; simulating a surface disinfection by the first UVGI source by: selecting a point on the surface; determining a distance from the point to the first UVGI source; determining an irradiance intensity for the point based on the irradiance data; receiving a susceptibility coefficient for the surface; determining an effective susceptibility for the subject microbe based on the base susceptibility and the susceptibility coefficient; and determining a first microbe reduction function for the subject microbe.

(FR) L'invention concerne un procédé de simulation d'irradiation germicide aux ultraviolets (IGUV) d'un microbe sujet dans une pièce, le procédé consistant à : générer un modèle 3D de la pièce ; recevoir des données d'éclairement énergétique associées à la source IGUV ; recevoir une susceptibilité de base pour le microbe sujet ; simuler une désinfection de surface par la première source IGUV par sélection d'un point sur la surface ; déterminer une distance du point à la première source IGUV ; déterminer une intensité d'éclairement énergétique pour le point sur la base des données d'éclairement énergétique ; recevoir un coefficient de susceptibilité pour la surface ; déterminer une susceptibilité efficace pour le microbe sujet sur la base de la susceptibilité de base et du coefficient de susceptibilité ; et déterminer une première fonction de réduction de microbe pour le microbe sujet.
