Covchav huvtxawv ntawm airflow tsim raws li qib sib txawv.Feem ntau, nws tuaj yeem muab faib ua ntsug laminar flow (Class1-100), kab rov tav laminar flow (Class1-1,000), thiab turbulent flow (Class1,000-100,000).Cov ncauj lus kom ntxaws sib txawv yog raws li nram no:
| Txoj kev Airflow | Kev huv huv | Cua ceev (/s) | Huab cua hloov pauv (/h) | Cua nkag | Qhov zoo | Qhov tsis zoo |
| Vertical laminar flow | Qib 1-100 | 0.25-0.40 Nws | 200-60 | Tshuab tawm: ntau tshaj 80% ntawm lub qab nthab.Kev nqus pa: ntau tshaj 40% ntawm phab ntsa vaj huam sib luag, kuj los ntawm sab vaj huam sib luag. | Cov nyhuv ua tiav, Tsis yooj yim cuam tshuam los ntawm cov neeg ua haujlwm thiab kev ua haujlwm,Nws yuav ruaj khov tam sim ntawd tom qab pib ua haujlwm,Muaj cov plua plav me me heev thiab rov ntab,Yooj yim tswj. | Ua tib zoo saib rau qhov chaw tsis muaj dab tsi hauv qab nthab ( teeb pom kev zoo, thiab lwm yam) Nws yog qhov teeb meem los hloov qhovlim,Cov khoom siv raug nqi siab heev,Kev nthuav dav ntawm lub tsev yog qhov nyuaj dua. |
| Kab rov tav laminar flow | Chav Kawm 1 - Chav Kawm 1,000 | 0.45-0.50 Nws | 200-600 100-200 | Tshuab tawm: ntau tshaj 80% ntawm cov siding.Inhalation: ntau tshaj 40% ntawm lub sab, kuj los ntawm lub qab nthab. | Nws ua ruaj khov tam sim ntawd tom qab pib ua haujlwm, thiab cov qauv yooj yim. | Kev cuam tshuam ntawm cov dej ntws tawm yuav tshwm sim hauv qab, Kev mloog yuav tsum tau them rau kev teeb tsa thiab kev tswj hwm ntawm cov neeg ua haujlwm thiab cov tshuab,Cov khoom siv raug nqi siab heev,Kev nthuav dav ntawm lub tsev yog qhov nyuaj dua. |
| Turbulent flow (tseem ceeb) | Chav Kawm 1,000- Chav Kawm 100,000 | 30-60 | Tshuab tawm: lub lim muaj qhov hluav taws xob zoo dua.Inhalation: los ze rau hauv pem teb. | Cov qauv yooj yim, Cov cuab yeej siv qis,Lub expansion ntawm lub tsev yog yooj yim dua,Yog tias koj ntxiv lub rooj tsis muaj plua plav, koj tuaj yeem ua kom huv huv. | Cov pa phem tuaj yeem nkag mus rau sab hauv tsev vim yog qhov cua turbulence Nws yuav siv sij hawm ib ntus kom ncav cuag lub xeev ruaj khov,Kev saib xyuas yuav tsum tau them rau kev teeb tsa thiab kev tswj hwm ntawm cov neeg ua haujlwm thiab cov tshuab. |
