Answer 2

Answer:

Ventilators are provided in the rooms at the top of the roofs because if the air inside the room gets hot, the hot air rises up and flows through these ventilators and thus cool air remains at bottom. It brings cool and fresh air in the room.Thus ventilators maintain conventional currents to keep the air fresh in the room.

Explanation:

Stephanie Desmon talks with Ana María Rule, PhD ’05, MHS ’98, a ventilation expert and assistant professor in Environmental Health and Engineering, about how ventilation systems can reduce the risk of exposure, whether heating and air conditioning are different, and whether airplanes’ ventilation systems are better or worse than buildings’. Rule also breaks down a case study of a restaurant in China that traced an outbreak of COVID-19 to poor ventilation.
