Puas yog qhov ntsuas qhov ntsuas ntawm qhov ntsuas carbon dioxide ntau npaum li qhov ua tau?
Kev faib tawm ntawm cov pa roj carbon dioxide:
(1) 250 ~ 350ppm - huab cua sab nraum zoov ib txwm muaj.
(2) 350 ~ 1, 000ppm—tus nqi ib txwm nyob hauv qhov chaw muaj cua zoo.
(3) 1,000~2,000ppm—theem ntawm oxygen-tsis muaj oxygen, cua tsaug zog uas ua rau muaj kev tsis txaus siab.
(4) 2,000~5,000ppm—theem stagnant, stale, cua txias. Mob taub hau, tsaug zog, nrog rau kev nyuaj siab, txo qis concentration, sib tw lub plawv, thiab xeev siab me ntsis.
(5) > 5,000 ppm—Qhov tshwm sim tuaj yeem ua rau tsis muaj oxygen, ua rau lub hlwb puas tsuaj mus tas li, tsis nco qab, thiab txawm tuag.
Tam sim no, cov pa roj carbon dioxide detectors ntawm kev ua lag luam muaj qhov ntsuas ntawm 0-100 feem pua VOL.
Tsawg concentration: los ntawm 0-2000ppm/3000ppm/5000ppm/10000ppm, (1ppm yog chav tsev roj, 1ppm yog hais txog qhov ntim piv ntawm ib lab.)
Cov ntsiab lus siab: los ntawm 0-5 feem pua / 10 feem pua / 20 feem pua / 40 feem pua / 50 feem pua / 100 feem pua VOL. (% VOL yog ntim piv)
Qhov kev ntsuas loj heev yog 100 feem pua VOL, uas yog hais tias, qhov chaw muaj cov pa roj carbon dioxide.
Txhawm rau ua kom tiav, peb tuaj yeem pom tias qhov ntsuas qhov ntsuas ntawm lub ntsuas carbon dioxide tsis loj npaum li qhov ua tau. Nws qhov kev ntsuas ntau yuav tsum raug xaiv raws li koj qhov chaw nyob hauv cov pa roj kom muaj txiaj ntsig kom pom tseeb dua. Cov lus qhia tshwj xeeb Koj sab laj nrog cov kws tshaj lij ntawm Yiyuntian, thiab lawv yuav xaiv qhov tsim nyog rau koj raws li koj xav tau thiab ua ke nrog qhov chaw siv.
