Air-conditioning systems

Hygienic quality of air-conditioning systems

The Task

Air-conditioning systems are used for the purpose of replacing interior air as far as this is necessary for hygienic reasons and to remove pollution of interior air, for example caused by hazardous substances that are released by materials or during production processes. Air-conditioning systems have the purpose to ensure the well-being of human beings in enclosed spaces and to thus make a vital contribution to maintaining their health and working ability.

The challenge

• Indoor pollution puts a burden on the human body (SBS: Sick Building Syndrome, BRI: Building Related Illness) and as a result it leads to reduced quality of life, reduced working capacity through to an inability to work.
• When germs die, they release "cadaveric poisons" that may cause health problems including tiredness, fatigue and toxic reactions. Microbial processes in ventilation systems can also lead to allergies (e.g. asthma, allergies to mould, etc.), unpleasant odours, extrinsic allergic alveolitis (EAA), etc.
• The VDI guideline 6022 provides for hygiene requirements for the construction, operation and maintenance of ventilation systems, in order to prevent hygiene deficiencies in and on air-conditioning equipment as well as possible resulting health problems - within the framework of the current state of science and technology.
