Hygiene inspection of ventilation systems
Ventilation systems (air-conditioning systems) have to be operated in such a way that the room temperature is comfortable for the users and that these systems do not pose any health risks, adversely affect well-being or produce odours.
The VDI guideline 6022 "Hygienic requirements for ventilation and air-conditioning systems" describes the current technology available to achieve this goal. It applies to all ventilation and air-conditioning systems in offices, meeting rooms, schools, indoor swimming pools, administrative buildings and production sites. In line with this VDI, hygiene inspections are to be carried out every 2 to 3 years depending on the system type. If systems with spray or evaporation humidifiers are in operation, the humidifier water has to be inspected by personnel trained in hygiene.
