Air Quality - Poor air and the demand-controlled ventilation

poor air

Carbon dioxide affects air quality
Although carbon dioxide (CO2 ) is non-toxic at low concentrations in the ambient air for the people it affected his well-being crucial. Carbon dioxide already tired from a concentration of 800 ppm. Since humans exhale carbon dioxide, this value is in closed rooms with many people quickly reached (meeting rooms, etc.). One speaks of poor air.

With our carbon dioxide detection systems you can regulate the ventilation of enclosed spaces and buildings depending on the number of persons, so that:

  • the energy consumption is as low as possible (demand-oriented ventilation) and
  • the present persons not tire prematurely.

 

ventilation

Demand-controlled ventilation
A permanent ventilation through open windows increases the energy consumption, the resulting draft leading to colds and is perceived as unpleasant. Demand-controlled ventilation prevents from this.To maintain the air quality (IAQ, Indoor Air Quality) a demand-controlled ventilation (DCV) is therefore necessary in such rooms and buildings.

Carbon dioxide is considered as the lead compound for pollutants that can trigger the "Sick Building Syndrome". The hygienic guideline for indoor use is in accordance with DIN 1946-2 at 1500 ppm CO2.

 

Optimal solution
Our sensors can measure the air quality and at poor air demand-controlled ventilation. The infrared measuring system used in our products determines the absolute carbon dioxide in the ambient air (partial pressure), constantly monitors itself and signals malfunctions of the hard- and software. The entire measuring range is linear. Depending on the application, the ambient temperature and measuring range, we offer a wide range of products.
