Innovative ventilation system protects against indoor infections
Aerosols in the air we breathe carry a high risk of infection. This can make working indoors, such as in open-plan offices, an unhealthy affair if regular ventilation is not provided. An innovative ventilation system promises to remedy the situation.
Wherever there are many people indoors, such as in open-plan offices or even in classrooms, there is a risk of poor air quality. Study of the FOPH already revealed in 2019 that the air quality in around two-thirds of all classrooms is insufficient. In the meantime - as we know - this situation has been exacerbated by Corona. This is because aerosols contaminated with viruses from the air we breathe pose a major risk of infection. Regular ventilation can reduce this risk, but it has the disadvantage that a lot of heating energy is wasted, especially during the cold season.
Innovative ventilation system that reduces the risk of infection
A solution to this dilemma is promised by an innovative ventilation system: Vitovent P-200. This ventilation system was developed by Viessmann, one of the leading providers of heating, ventilation and air conditioning solutions in Switzerland. Vitovent 200-P works according to the displacement flow principle (see Explainer video). In the process, the ventilation system directs fresh air into the room, where it is distributed over the floor. Vitovent 200-P then uses the body heat of the people present. This is sufficient to set air circulation in motion. The clean air on the floor rises and is inhaled. The stale exhaled air - including aerosols of people potentially infected with covid - also rises and reaches the Vitovent 200-P at the ceiling with the air flow. There, the so-called HEPA particulate air filter (High Efficiency Particulate Air) filters more than 99.995 percent of all aerosols from the extract air. Then, cleaned and enriched with fresh air from outside, it flows back into the room at floor level.
Immediately available and energy efficient
Vitovent 200-P is suitable for retrofitting indoors, is available immediately and can be commissioned within half a working day, the manufacturer writes. While surge ventilation, which is recommended in Corona times to reduce the risk of infection, wastes a lot of energy and thus contributes to climate change, the Viessmann ventilation system recovers up to 96% of energy from the warm, stale indoor air, it adds.
