Our reason for discussing severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) or 2019 novel corona virus (Covid-19), is to understand its aerosol transmission characteristics in indoor spaces and to mitigate further spread of this disease by designing a new HVAC system. The problem that we are tackling is the spread of covid-19 droplets through aerosol transmission by looking at potential engineering solutions to the existing HVAC systems. The purpose is to eradicate the spread of the COVID-19 by testing indoor spaces in an effort to understand the effectiveness of ventilation controls. We believe that scientists and engineers have not created an environmental controls system to combat Covid-19 in the indoor environment. The goal is to answer this need and construct an innovative HVAC model with highly efficient filtration and ventilation. The methodology is to conduct an epidemiological investigation by researching case studies and scientific results of COVID-19 pathogen fluid dynamics in enclosed spaces, as well as its effect on pre-symptomatic, symptomatic, and asymptomatic individuals. This invention would be impactful because it would greatly improve commercial and residential air quality in buildings. The effects of this HVAC ingenuity would prevent the concentration of corona virus2 aerosol droplets from recirculating in indoor settings. This study suggests that it is critical and very important to prevent over-crowding and provide ample ventilation and filtration of the circulating air in buildings. Our findings will help to identify solutions in improving ventilation standards, and integrate newer technology to upgrade HVAC-R systems.
