HVAC System Design Guidelines for COVID-19

COVID-19 Pandemic

WHO declared COVID-19 as Pandemic causing respiratory illness (like the flu) with symptoms such as a cough, fever, difficulty breathing, body ache etc. As per current scope & definition of modes of transmission by WHO released guidelines, SARS-Coronavirus Size 88nm to 160nm (0.088 micron to 0.160 micron) transmission is considered through Opportunistic Airborne & droplet mode Only. However, residual contaminants can travel through air currents caused by central air conditioning system ducts, where all or some air in the building is circulated and can contribute to the spread of the disease. COVID19 is fairly new and should be seriously considered with all the precautionary measures. The HVAC systems should be looked at as airborne infectious disease. Corona patients based on their nature of illness must be kept isolated in isolation centers and should not be mixed up with other areas of a hospital. That is why China has built dedicated centers for this. Now, if a hospital with Corona patients having mixed HVAC system, means there is a possibility of cross contamination and its spread. If an existing Hospital with Central AC system is used as Corona centers, its AC system needs to be looked at.
