Abstract

Denne oppfinnelsen angår en fremgangsmåte ved hjelp av hvilken det er mulig, med høyest mulig presisjon og uten store kostnader, å bestemme lufttettheten av etlukket rom hvor et slikt rom er særlig godt egnet til anvendelse av inertgassbrannslukkingsteknologi beskrevet ovenfor.Spesifikt innføres en fremgangsmåte som, ved behov og på en effektiv men lett å implementere måte, tillater på ethvert tidspunktoppdatert bestemmelse av den eksisterende lufttetthet i det lukkede rom uten å kreve komplekse testserier. For å oppnå en slik virkning er det første trinn i henhold til oppfinnelsen å justere en konsentrasjonsgradient mellom den interne luftatmosfære i et lukket rom og omgivelsesluftatmosfæren ved å sette den molare konsentrasjonen av minst én bestanddelskomponent i det indre roms luftatmosfære, særlig oksygen, på en verdi som avviker fra den molare konsentrasjonsverdien til den minimum ene tilsvarende komponent i omgivelsesluftatmosfæren. Dette blir fulgt av en bestemmelse av konsentrasjonsendringshastigheten ved at, i luftatmosfæren i det indre rom, den tidsbaserte endring av den molare konsentrasjon av den minimum ene bestanddelskomponent blir målt. Avslutningsvis, ved å ta inn i beregningen den tidligere bestemte konsentrasjonsendringshastigheten, blir lufttetthetsverdien til det lukkede rom beregnet.
