A school in Mainz has installed an innovative ventilation system in its classrooms to allow for a safer return to school for its students, as seen on Friday.
“The Max Planck Institute for Chemistry in Mainz together with a research group lead by Frank Helleis designed the system to find a simple, easily buildable solution, to provide fresh air in the classroom and to extract aerosols,” said Dr Elena Klimach, a teacher at the IGS Mainz Hechtsheim school, a middle and high school in Rhineland-Palatinate’s capital.
“The warm air rises, taking the aerosols which could contain infectious materials with it. The funnel gathers it and guides it towards the suction tube, and it goes through the system of pipes towards the ventilator, and the ventilator pushes it through the window and outside. Air can flow in through another window, one which is ajar for example,” said Dr Klimach, as she explained how the ventilation process works.
Dr Klimach added the reaction has been overwhelmingly positive and said “in Mainz it is also the case that the parents built the system themselves. So, in Mainz primary schools and partly in secondary schools. Only the window connections and the fans were installed by specialist staff.”
Rhineland-Palatinate will open kindergartens and welcome back primary school children on Monday, while secondary school are expected to open on March 15, depending on the state of the pandemic.
Germany extended its lockdown until 28 March. The country has registered nearly 2.5 million confirmed cases of coronavirus and over 71,000 deaths with COVID-19.
