Correct ventilation in kindergartenFresh and healthy air in kindergarten - a special topic
For kindergartens, ventilation is the most important measure to protect against infection with infectious diseases. Other hygienic protective measures such as keeping your distance or adhering to sneezing and coughing labels are difficult to implement in a group of small children. In addition to avoiding infection, the CO2 concentration in day-care centers is also decisive.
The Federal Environment Agency recommends maintaining an average CO2 concentration of 1,000 ppm for day-care centers. Ventilation concepts in kindergarten can therefore be designed in accordance with DIN EN 15251: 2012 and DIN EN 16798-3.
Depending on which classification is agreed, outside air volume flows between 20 and 36 m³ / h per person are recommended. The combination of mechanical ventilation with heat recovery and window ventilation is an effective solution for exchanging the air according to the recommendations of the Federal Environment Agency without the rooms cooling down too much, the children having to freeze and without expensive reheating. The ventilation in the kindergarten through wide-open windows is thus reduced to a minimum.
Planning example & conceptfor ventilation in kindergarten
Between 20 and 36 m³ / h per person
In this case, the iV-Office is designed with 30 m³ / h per device, resulting in an outside air volume flow of 120 m³ / h with 4 devices in the room (two pairs of devices). This corresponds to 10 m³ / h per person with a group of 12 people. In addition, the air exchange rate can be temporarily increased to up to 180 m³ / h before and after use. In addition to the removal of CO2, the mechanical ventilation in the kindergarten also prevents infections.
Existing aerosols are transported to the outside via the devices and the fresh air supplied lowers the concentration of viruses in the room air. In order to achieve the necessary air exchange in this application, the ventilation should be supported by opening the windows from time to time. Holistic ventilation in the kindergarten can be achieved by combining inVENTer ventilation with additional window ventilation at peak times.
Conclusion on the subject of air in kindergarten
The iV-Office creates continuous basic ventilation within the specified sound emission requirements (here 40 dB (A)).
