Abstract

Modern humans spend 90% of their time indoors, and the fact indoor air is 2-5 times worse than outdoor air. During the Covid outbreak, humans are very concerned about air quality, where they spend most of their time in air-conditioned (AC) rooms. It may be used in various ways, one of which is installing a HEPA filter in the AC system. It can assist in preventing the virus from spreading through the air, but since this kind of filter has a significant pressure drop, it requires a lot of changes to be used on conventional AC. This thesis will study, design, monitoring and control systems as well as filters and Ultraviolet C that can be applied to existing commercial AC without much modification of the existing system and produce clean air quality, reduce the spread of viruses and particles that harm humans and also monitor the quality of the air for commercial AC. The devices can help minimize particulate matter, enhance ventilation in AC spaces, and lower CO2 levels. The project's findings are reasonably good, with lower PM 2.5 and CO2 levels, allowing for better air quality in the AC room and reducing the spread of viruses by airborne transmission.
