Abstract
En framgangsmåte og et anlegg for frembringelse av pusteluft med lavere prosentandel oksygen enn normal puste- luft i et lukket rom (1), idet trykket i rommet opprettholdes lik trykket av omgivende atmosfære. Ved utførelse av oppfinnelsen iverksettes aktiviteter som isolert sett ville senke oksygen- nivået i det'lukkede området til et ikJce-pustbart nivå, idet man ved hjelp av en oksygenkontrollanordning (14) og en med denne samvirkende vifte- anordning (7), styrer en utveksling ev pusteluften i rommet med luft fra den omgivende' atmosfære slik at oksygen- nivået i rommet stabiliseres på forut- bestemt nivå. Samtidig blir oppstående gasser, sarlig C02, som ellers ville redusere kvaliteten av pusteluften i rommet (1), filtrert bort ved hjelp av en filteranordning (16).A method and a plant for producing breathing air with a lower percentage of oxygen than normal breathing air in a closed room (1), the pressure in the room being maintained equal to the pressure of ambient atmosphere. In carrying out the invention, activities which, in isolation, would lower the oxygen level in the closed area to an inflatable level, controlling by means of an oxygen control device (14) and one with this cooperating fan device (7). exchanging possible breathing air in the room with air from the surrounding atmosphere so that the oxygen level in the room is stabilized at a predetermined level. At the same time, rising gases, especially CO 2, which would otherwise reduce the quality of the breathing air in the room (1), are filtered off by means of a filter device (16).
