Luftkvalitet og ventilasjonsstyring i Bømlafjordtunnelen

Abstract

Målet var å skaffe kunnskaper om forholdene i den 7860 m lange undersjøiske Bømlafjordtunnelen for å optimalisere ventilasjonen. Data fra kontinuerlige målere (NO, CO, støv, vindfart, temperatur, luftfuktighet og ventilasjon) for seks uker i 2001/02 ble analysert. Konsentrasjonene av CO, NO og støv var under grenseverdiene. Korrelasjonen var 0,623 for NO og støv, 0,425 for NO og CO, i målepunkt en. En PLS1-modell for NO basert på CO og støv ble utviklet og testet på data fra seks nye uker, korrelasjon mellom målte og utreknede verdier ble 0,829. The objective was to gain more knowledge about the air quality in the 7860 m long undersea Bømlafjord tunnel to improve the ventilation. Measured data from continuous analysers (NO, CO, PM10, air flow, temperature, air moisture and ventilation) for six weeks in 2001/02 were analysed. The concentration of CO, NO and PM10 were below Norwegian air quality standards. The correlation between NO and PM10 was 0.623, between CO and NO 0.425, in measuring point one. A PLS1 model for NO based on CO and PM10 was developed and tested on measured data for six new weeks, the correlation between measured and calculated values was 0.829.
