UVC Light Simulation for Room Disinfection System

Viruses are minuscule parasites that have gained notoriety for causing diseases. However, these harmful pathogens can be inactivated using Ultraviolet-C (UVC) radiation has a wavelength between 200 – 280 nm. The wavelengths of the UVC responsible germicidal effect as proteins (e.g. RNA and DNA) absorb maximum in damage DNA viruses so they cannot replicate. This project aimed to simulate light intensity different room layouts guide evaluation effectiveness surface disinfection system which consists lights. Besides determining quantity installation layout lights, also help visualisation coverage highlight any under-exposed area optimum simulation software. DIALux Evo 9.1 was used lighting layouts. As software only calculates normal visible (wavelength 380 700 nm) unit Lux, correlation Lux dosage (mJ/cm2) must established first. A minimum 40 mJ/cm2 is required achieve complete microorganisms. able visualize determine placement lights ensure sufficient delivered every critical surface. outcome this design especially hospital wards setting optimise reducing risk infection.
