ASHRAE "Filter and air purification technology position" sau cov ntsiab lus tseem ceeb

Thaum ntxov xyoo 2015, American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) tau tshaj tawm Daim Ntawv Qhia Txog Txoj Haujlwm ntawmLim thiab Cua NtxuavTshuab.Cov koom haum cuam tshuam tau tshawb nrhiav cov ntaub ntawv tam sim no, pov thawj, thiab cov ntaub ntawv, suav nrog ASHRAE cov ntawv tshaj tawm, ntawm kev ua tau zoo ntawm yim lub thev naus laus zis suav nrog kev siv tshuab xov xwm, lim hluav taws xob, adsorption, ultraviolet lub teeb, photocatalytic oxidation, huab cua huv, ozone, thiab qhov cua.Cov teebmeem kev noj qab haus huv ntawm cov neeg nyob sab hauv tsev, cov teebmeem mus sij hawm ntev, thiab cov kev txwv raug tshuaj xyuas tag nrho.

Daim ntawv qhia txoj haujlwm muaj ob lub ntsiab lus sib txawv:

1. Raws li kev pom ntawm qhov tsis zoo ntawm ozone thiab nws cov khoom siv tshuaj tiv thaiv rau tib neeg kev noj qab haus huv, ozone yuav tsum tsis txhob siv rau kev lim dej hauv qhov chaw sab hauv.Txawm hais tias ozone tsis siv rau kev ua kom huv, yog tias cov cuab yeej ua kom huv tuaj yeem tsim kom muaj ntau cov ozone thaum lub sijhawm ua haujlwm, yuav tsum muaj kev ceev faj siab.

2. Tag nrho cov tshuab lim dej thiab huab cua huv yuav tsum muab cov ntaub ntawv ntawm kev tshem tawm cov pa phem raws li txoj kev sim tam sim no, thiab yog tias tsis muaj txoj hauv kev, yuav tsum muaj kev ntsuam xyuas los ntawm lub koom haum thib peb.

Cov ntaub ntawv qhia txog txhua yam ntawm yim technologies.

1. Mechanical filtration lossis porous media filtration (Mechanical filtration or Porousmedia particle filtration) muaj qhov pom tseeb heev ntawm cov teeb meem me me thiab muaj txiaj ntsig zoo rau tib neeg kev noj qab haus huv.
2. Cov ntaub ntawv pov thawj qhia tau hais tias vim muaj kev sib raug zoo nrog ntau lub xeev tsis txwv, kev tshem tawm ntawm cov ntxaij lim dej hluav taws xob ntawm cov teeb meem hauv huab cua nthuav tawm ntau qhov loj: los ntawm qhov tsis zoo mus rau qhov zoo heev.Ntxiv mus, nws cov nyhuv ntev yog cuam tshuam nrog lub xeev ntawm kev saib xyuas ntawm lub cuab yeej.Txij li thaum electrofilters ua haujlwm ntawm lub hauv paus ntsiab lus ntawm ionization, muaj kev pheej hmoo ntawm ozone tiam.
3. Sorbent muaj qhov pom tseeb tshem tawm ntawm cov pa phem.Cov kev tshawb fawb tau pom tias tib neeg qhov hnov ​​​​tsw tsw muaj txiaj ntsig zoo rau nws qhov kev tshem tawm.Txawm li cas los xij, tseem muaj pov thawj ncaj qha tsis txaus seb nws puas muaj txiaj ntsig rau kev noj qab haus huv.Txawm li cas los xij, lub cev adsorbents tsis muaj txiaj ntsig zoo rau txhua qhov ua paug.Nws muaj kev cuam tshuam ntau dua ntawm cov khoom tsis muaj polar organic, kub kub taw tes, thiab loj molecular hnyav gaseous pa phem.Rau qhov tsis tshua muaj siab ntawm cov khoom uas muaj qhov hnyav dua 50 thiab siab polarity, xws li formaldehyde, methane thiab ethanol, nws tsis yooj yim rau adsorb.Yog hais tias tus adsorbent thawj adsorbs cov pa phem uas tsis muaj qhov hnyav molecular, polarity thiab qis boiling point, thaum nws ntsib tsis-polar organic teeb meem, siab boiling point, thiab gaseous pollutants nrog loj molecular hnyav, nws yuav tso tawm (desorb) ib feem ntawm yav tas los adsorbed pa phem. , uas yog, muaj kev sib tw adsorption.Tsis tas li ntawd, txawm hais tias physisorbents yog rov tsim dua, kev lag luam tsim nyog xav txog.
4. Qee cov kev tshawb fawb tau pom tias photocatalytic oxidation muaj txiaj ntsig zoo hauv kev decomposing organic teeb meem thiab kab mob, txawm li cas los xij, tseem muaj pov thawj tias nws tsis muaj txiaj ntsig.Photocatalyst siv ultraviolet rays los irradiate nto ntawm lub catalyst los txhawb lub decomposition ntawm cov teeb meem tshuaj rau nws mus rau hauv carbon dioxide thiab dej, tab sis nws cov nyhuv muaj feem xyuam rau lub sij hawm sib cuag, huab cua ntim, thiab qhov chaw ntawm lub catalyst.Yog tias qhov tshuaj tiv thaiv tsis tiav, lwm yam khoom tsis zoo xws li ozone thiab formaldehyde kuj raug tsim.
5. Kev tshawb fawb qhia tau hais tias lub teeb ci ultraviolet (UV-C) tuaj yeem ua tau zoo hauv kev tiv thaiv kev ua qias tuaj lossis tua lawv, tab sis yuav tsum ceev faj txog ozone.
6. Ozone (Ozone) yog teeb meem rau tib neeg kev noj qab haus huv.Qhov tso cai raug txwv tsis pub tshaj tawm los ntawm ASHRAE Environmental Health Committee hauv 2011 yog 10ppb (ib feem ntawm 100,000,000).Txawm li cas los xij, tam sim no tsis muaj kev pom zoo ntawm tus nqi txwv, yog li raws li txoj cai ceev faj, kev siv tshuab ua kom huv uas tsis tsim ozone yuav tsum tau siv ntau li ntau tau.
7. Cua purifier (Packaged cua nqus tsev vacuum) yog ib yam khoom siv ib los yog ntau yam cua purification technologies.
8. Qhov cua tshuab yog ib txoj hauv kev zoo los tshem tawm cov pa phem hauv tsev thaum huab cua sab nraum zoov zoo.Kev siv cov lim dej thiab lwm yam kev siv tshuab ntxuav cua tuaj yeem txo qhov kev xav tau ntawm qhov cua.Thaum huab cua sab nraum zoov tsis zoo, qhov rooj thiab qhov rais yuav tsum raug kaw.

Thaum lubsab nraum cua zooyog qhov zoo, qhov cua yog qhov kev xaiv zoo tshaj plaws.Txawm li cas los xij, yog tias huab cua sab nraum zoov muaj kuab paug, qhib qhov rais rau qhov cua yuav tshuab cov pa phem sab nraud rau hauv chav, ua rau muaj kev puas tsuaj ntawm cov pa phem hauv tsev.Yog li ntawd, lub qhov rooj thiab qhov rais yuav tsum raug kaw nyob rau lub sijhawm no, thiab cov cua purifiers yuav tsum tau qhib kom sai sai tshem tawm cov pa phem hauv tsev.

Raws li kev puas tsuaj ntawm ozone rau tib neeg kev noj qab haus huv, thov ceev faj txog cov khoom siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob los ua kom huv huv huab cua, txawm tias cov khoom zoo li no tsim cov ntaub ntawv soj ntsuam los ntawm cov chaw soj ntsuam.Vim tias cov khoom siv kuaj hauv hom kev tshuaj xyuas no yog tag nrho cov tshuab tshiab, cov av noo thaum lub sij hawm kuaj tsis tau hloov.Thaum cov khoom siv rau ib lub sijhawm, cov plua plav loj tuaj yeem sib sau ua ke nyob rau hauv high-voltage ib feem, thiab nws yog ib qho yooj yim heev los tsim qhov tshwm sim tawm, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntawm cov av noo nyob rau sab qab teb, qhov twg huab cua noo feem ntau yog. siab li 90% lossis siab dua, thiab qhov tshwm sim ntawm qhov hluav taws xob tawm hluav taws xob ntau dua yuav tshwm sim.Lub sijhawm no, sab hauv tsev Lub ozone concentration yog yooj yim dua li tus qauv, uas ncaj qha ua rau kev noj qab haus huv ntawm cov neeg siv.

Yog tias koj tau yuav cov khoom lag luam nrog cov cuab yeej hluav taws xob hluav taws xob hluav taws xob siab (cua purifier, huab cua tshiab), thaum qee zaum koj hnov ​​​​tsw tsw ntxhiab tsw ntxhiab tsw thaum koj siv nws, koj yuav tsum ceev faj rau lub sijhawm no, nws yog qhov zoo tshaj rau qhib qhov rais. rau qhov cua thiab kaw nws tam sim ntawd cov khoom.
