How to optimize your ventilation concept in Corona times

Large rooms, such as those found in universities, schools, hotels, museums or even in the workplace, have an increased rate of infection by pathogens. The reason for this is that several people come together over a long period of time and tiny particles suspended in the air promote infection.

This can be counteracted by controlled natural ventilation. In our blog post, we will show a simple and convenient ventilation solution that is suitable for any type of large space.

 

What is Controlled Natural Ventilation and how can it help?

Controlled natural ventilation (or KNL) refers to the exchange of air through windows, which can be controlled, for example, by electric window drives, and can also be operated automatically.

In this way, the company D+H Mechatronic AG was able to develop a ventilation solution that meets the most important recommendations of the German Federal Environmental Agency (UBA) and the Conference of Ministers of Education and Cultural Affairs (KMK). The principle is both clever and simple: a digital user interface allows a room to be ventilated either automatically or manually using window drives.

There are two variants for automated ventilation:
Either you ventilate according to time - for example every 20 minutes - or you ventilate according to CO2 value. The latter is indicated by a traffic light system on the display and measured by a so-called CO2 sensor. As soon as the CO2 concentration is in the critical range, the chain drives extend automatically - quietly and with little disturbing background noise.

 

Optionally, the ventilation solution offers a password-protected user interface. In addition, a presence detector can be fitted to stop the motor drive as soon as someone is in the closing area. This is very practical for schools with younger students, for example.

 

Controlled natural ventilation is particularly useful for schools and universities, as fresh air has been proven to increase the ability to concentrate. Another advantage is the automation of the window drives: this means that lessons or lectures do not have to be interrupted by manually opening the windows, and the ventilation regulations of the health authorities are observed.

 

Energy-efficient ventilation is also possible thanks to the D+H ventilation solution. Due to the short, but efficient, air exchange, the room does not continuously lose heat, as is the case when windows are tilted, for example. Accordingly, the room always cools down only briefly - ideal conditions, therefore, to convince even frostbite sufferers in the office to ventilate.

However, the most important thing about the whole thing is and remains: Ventilation protects.
