Most of the roofs of buildings are equipped with exhaust pipes to balance the air pressure of the sewage pipes. However, if the exhaust flow rate of the exhaust pipes is large, an airflow vortex will be formed around the exhaust port, causing the exhaust gas to flow downward, resulting in a "turbulence effect". - Airflow with viruses and bacteria will flow back into the room through windows or vents in high-rise units. Experts pointed out that the cluster infection cases in many residential estates are suspected to be related to the exhaust pipes of the buildings.
