Title | New ventilation system helps protect healthcare workers from Covid-19 infection |
---|---|
Description | Professor John Lin Zhang, Head of Division of Building Science and Technology (BST) at City University of Hong Kong (CityU), developed an innovative ventilation system called stratum ventilation. The air supply and exhaust for the stratum ventilation system can be placed strategically in different positions for a particular functional location. The supply can be placed in the middle of a wall while the exhaust can be placed near the floor, thus minimising the mixing of fresh and obsolete air in a hospital ward. “The system allows the fresh air to flow out horizontally, where it first reaches the breathing zone of the healthcare workers and then that of the patients. Finally, the air stream with possible pathogens is exhausted through the outlets above the floor near the patients’ headboards. This not only positions healthcare workers in the ‘upstream’ part of the supply airflow, but also dilutes and expels the airborne contaminants in the ward effectively,” Professor Lin said. |
