Abstract
Dette projekt forklarer, hvorfor luftfiltre bruges i luftbehandlingsanlæg (Air Handling Units, AHU), som cirkulerer og konditionerer luft i bygninger. Det beskriver overordnet, hvordan den nye internationale standard ISO 16890 adskiller sig fra den tidligere europæiske standard EN 779. Studiet gennemgår også almindelige strategier for, hvornår filtre udskiftes, og drøfter, hvordan disse praksisser kan forbedres. For at underbygge diskussionen med virkelige data overvåger projektet brugte filtre leveret af den danske ventilationsproducent Airmaster og undersøger, hvordan relativ luftfugtighed og trykfald (modstanden mod luftstrøm gennem et filter) påvirker disse filtre.
This project explains why air filters are used in Air Handling Units (AHUs), the systems that circulate and condition air in buildings. It outlines how the new international ISO 16890 standard differs from the earlier European EN 779 standard. The study also reviews common strategies for deciding when to replace filters and discusses how these practices could be improved. To ground the discussion in real-world data, the project monitors used filters supplied by the Danish ventilation manufacturer Airmaster and investigates how relative humidity (moisture in the air) and pressure drop (the resistance to airflow across a filter) affect those filters.
