Mitigate Coronavirus with HVAC!

With the rapid spread of coronavirus around the world and especially in the US, restaurants and businesses are doing all they can to prevent the spread of coronavirus. But are they doing enough? 

The World Health Organization has shown the coronavirus to be airborne, which means it can be spread through heating, ventilation, and air conditioning systems. As a result, new California regulations allow only outside seating for restaurants. However, for those that work inside the buildings, poor ventilation is still a concern.

Business owners have a responsibility to ensure the safety of their staff by optimizing ventilation and indoor airflow. 

Listed below are important steps that can be taken to greatly minimize the spread of bacteria and the virus. 

  1. Increase the fresh air rate of exchange from outside the building in ducted HVAC systems to minimize the recycling of air within the building. 
  2. Replace fixed-speed fan motors variable-speed fan motors for increased control over airflow.
  3. Install air-purification systems. Minimum Efficiency Reporting Value (MERV) filters rated 17 or higher and High-Efficiency Particulate (HEPA) filters are most effective in filtering out the smallest particles, which includes coronavirus particles. These filters are not guaranteed to filter out the virus, but they can reduce the risk of airborne transmission.
  4. Use a vertical laminar airflow to minimize in-room transmission. Air conditioners that release air horizontally into a room can push particles from one area to another, quickly spreading the virus. A vertical airflow (from ceiling to floor) will prevent the rapid movement of air from one area to another. If systems for vertical airflow do not already exist, new structures and ventilation systems may have to be built.
