Ventilation in classrooms and offices
Best atmosphere for learning and working
The user-friendly D+H solution for effectively removing aerosols and CO2 by means of automated ventilation.
A D+H model solution for time-controlled, automated ventilation of a classroom provides for fresh air at the MaxS school (Max-Schmeling-Stadtteilschule) in the Marienthal district of Hamburg. The MaxS offers all school-leaving certificates up to the university entrance qualification (Abitur) and is characterised by the social, cultural and ethnic diversity of its students. In this open environment it was easy to win support with a model application of the D+H ventilation solution for classrooms and offices.
Our reference solution at the MaxS protects health and promotes the ability to concentrate
The model classroom can be ventilated manually or automatically based on defined time intervals or after a predefined CO2-limit value is exceeded. This means that this D+H solution complies with the most important recommendations from the German Federal Environment Agency (UBA) and Standing Conference of the Ministers of Education and Cultural Affairs (KMK).
The ventilation system is controlled by an intuitive user interface with password protection and user administration. The five extremely quiet chain drives can automatically and seamlessly open and close all windows as well as keep them in an open position. D+H window drives are burglary-resistant and, equipped with closing edge protection, they meet all the necessary safety requirements.
Two sensors mounted on the ceiling additionally ensure the safety of everyone who is present in the room. Firstly, a CO2 sensor automatically opens classroom windows as soon as the proportion of CO2 in the air exceeds a default limit value. Secondly, the presence detector prevents potential danger if anyone moves into the swivel range of a closing window.
