I-ASHRAE “Isikhundla sobuchwepheshe bokuhlunga nokuhlanzwa komoya” sibhala incazelo ebalulekile

Ekuqaleni kuka-2015, i-American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) yakhipha I-Position Paper on.Izihlungi Nokuhlanza UmoyaUbuchwepheshe.Amakomiti athintekayo asesha idatha yamanje, ubufakazi, kanye nezincwadi, okuhlanganisa nezincwadi ze-ASHRAE uqobo, ngokusebenza ngempumelelo kobuchwepheshe obuyisishiyagalombili obuhlanganisa ukuhlunga kwemishini yemidiya, izihlungi zikagesi, i-adsorption, ukukhanya kwe-ultraviolet, i-photocatalytic oxidation, izinto zokuhlanza umoya, i-ozone, kanye nokukhipha umoya.Imiphumela yezempilo yabantu abangaphakathi endlini, imiphumela yesikhathi eside, kanye nemikhawulo ibuyekezwa ngokuphelele.

Iphepha lesikhundla linamaphuzu amabili ahlukene:

1. Ngenxa yemiphumela emibi ye-ozone kanye nemikhiqizo yayo yokusabela empilweni yomuntu, i-ozone akufanele isetshenziselwe ukuhlanzwa komoya ezindaweni ezingaphakathi endlini.Ngisho noma i-ozone ingasetshenziselwa ukuhlanzwa, uma idivayisi yokuhlanza ingakwazi ukukhiqiza inani elikhulu le-ozone ngesikhathi sokusebenza, kufanele kunikezwe izinga eliphezulu lokuqapha.

2. Bonke ubuchwepheshe bokuhlunga kanye nokuhlanza umoya kufanele buhlinzeke ngedatha yokukhishwa kwezinto ezingcolile ngokusekelwe ezindleleni zamanje zokuhlola, futhi uma ingekho indlela efanele, kufanele kube nokuhlolwa okwenziwa yinkampani yangaphandle.

Lo mbhalo wethula ubuchwepheshe obuyisishiyagalombili.

1. Ukuhlunga ngomshini noma ukuhlunga kwemithombo yezindaba ezinamazinyo abushelelezi (Ukuhlunga ngomshini noma ukuhlunga kwezinhlayiyana ze-Porousmedia) kunomphumela osobala kakhulu wokuhlunga ezinhlayiyeni futhi kunenzuzo empilweni yomuntu.
2. Ubufakazi bubonisa ukuthi ngenxa yobudlelwano namapharamitha wombuso amaningi, umphumela wokususwa kwezihlungi ze-elekthronikhi entweni eyizinhlayiyana ezisemoyeni wethula ububanzi obukhulu ngokuqhathaniswa: ukusuka kokungasebenzi kahle ukuya kokusebenza kahle kakhulu.Ngaphezu kwalokho, umphumela wayo wesikhathi eside uhlobene nesimo sokugcinwa kwedivayisi.Njengoba ama-electrofilters asebenza ngomgomo we-ionization, kunengozi yokukhiqizwa kwe-ozone.
3. I-Sorbent inomphumela osobala wokususa ezintweni ezingcolisa igesi.Ucwaningo lubonise ukuthi inzwa yabantu yokuhogela inokuhlola okuhle ngomphumela wayo wokususa.Nokho, kusenobufakazi obuqondile obanele ukuthi kuyazuzisa yini empilweni.Kodwa-ke, ama-adsorbents angokwenyama awasebenzi ngokulinganayo kukho konke ukungcola.Inomthelela omkhulu kuzinto eziphilayo ezingezona ezomhlaba, indawo yokubilisa ephezulu, kanye nezinto ezingcolisa igesi ezinesisindo samangqamuzana amakhulu.Ngokugxila okuphansi kwezinto ezinesisindo samangqamuzana esingaphansi kuka-50 kanye ne-polarity ephezulu, njenge-formaldehyde, i-methane ne-ethanol, akulula ukukhangwa.Uma i-adsorbent iqala ngokukhanga ukungcola ngesisindo esiphansi samangqamuzana, i-polarity kanye nephuzu eliphansi lokubilisa, lapho ihlangana ne-non-polar organic, indawo yokubilisa ephezulu, kanye nokungcola kwegesi okunesisindo esikhulu samangqamuzana, izokhulula (i-desorb) ingxenye yokungcola okukhangisiwe ngaphambilini. , okungukuthi, kukhona ukuncintisana kwe-adsorption.Ngaphezu kwalokho, nakuba ama-physisorbents evuselelwa kabusha, ezomnotho kufanele zicatshangelwe.
4. Ezinye izifundo zibonise ukuthi i-photocatalytic oxidation iyasebenza ekuboleni izinto eziphilayo kanye nama-microorganisms, noma kunjalo, kukhona nobufakazi bokuthi ayinawo umphumela.I-Photocatalyst isebenzisa imisebe ye-ultraviolet ukuze ikhanyise ubuso be-catalyst ukukhuthaza ukubola kwezinto eziyingozi kuyo ibe yi-carbon dioxide namanzi, kodwa umphumela wayo uhlobene nesikhathi sokuxhumana, umthamo womoya, kanye nesimo esiphezulu se-catalyst.Uma ukusabela kungaphelele, ezinye izinto eziyingozi ezifana ne-ozone ne-formaldehyde zingase futhi zikhiqizwe.
5. Ucwaningo lubonisa ukuthi ukukhanya kwe-ultraviolet (UV-C) kungasebenza ngempumelelo ekuvimbeleni umsebenzi wokungcola noma ukuwabulala, kodwa qaphela i-ozone engenzeka.
6. I-ozone (i-Ozone) iyingozi empilweni yomuntu.Umkhawulo ovunyelwe wokuhlushwa wokuchayeka ophakanyiswe yiKomidi Lezempilo Lezemvelo le-ASHRAE ngo-2011 ngu-10ppb (ingxenye eyodwa kweziyi-100,000,000).Kodwa-ke, okwamanje akukho ukuvumelana ngenani lomkhawulo, ngakho-ke ngokomgomo wokuqapha, ubuchwepheshe bokuhlanza obungakhiqizi i-ozone kufanele busetshenziswe ngangokunokwenzeka.
7. Isihlanzi komoya (Isicoci somoya esipakishwe) siwumkhiqizo osebenzisa ubuchwepheshe obubodwa noma obuningi bokuhlanza umoya.
8. Ukungenisa umoya kuyindlela ephumelelayo yokususa ukungcola kwasendlini lapho izinga lomoya wangaphandle lilihle.Ukusetshenziswa kokuhlunga kanye nobunye ubuchwepheshe bokuhlanza umoya kunganciphisa isidingo sokungenisa umoya.Lapho umoya wangaphandle ungcolile, iminyango namafasitela kufanele kuvalwe.

Lapho i-izinga lomoya wangaphandlekuhle, ukungena komoya ngokungangabazeki kuyisinqumo esingcono kakhulu.Nokho, uma umoya wangaphandle ungcolile, ukuvula amafasitela okungenisa umoya kuzophephezela ukungcola kwangaphandle ekamelweni, okubhebhethekise ukuwohloka kokungcoliswa kwemvelo kwangaphakathi.Ngakho-ke, iminyango namafasitela kufanele kuvalwe ngalesi sikhathi, futhi izihlanzi zomoya ezijikeleza kakhulu kufanele zivulwe ukuze zisuse ngokushesha izinto ezingcolisa umoya zasendlini.

Ngenxa yokulimala kwe-ozone empilweni yomuntu, sicela uqaphe ngemikhiqizo esebenzisa ubuchwepheshe be-electrostatic obunamandla kakhulu ukuze ihlanze umoya, ngisho noma imikhiqizo enjalo ikhiqiza imibiko yokuhlola evela kuma-ejensi okuhlola.Ngenxa yokuthi imikhiqizo ehlolwe kulolu hlobo lombiko wokuhlola yonke iyimishini emisha, umswakama womoya ngesikhathi sokuhlolwa awukashintshi.Lapho umkhiqizo usetshenziswa isikhathi esithile, inani elikhulu lothuli libuthana engxenyeni ye-voltage ephezulu, futhi kulula kakhulu ukukhiqiza into ekhishwayo, ikakhulukazi endaweni enomswakama eningizimu, lapho umswakama womoya uvame ukufana. ukuphakama okungama-90% noma ngaphezulu, futhi ukwenzeka kokukhishwa kwamandla kagesi aphezulu kungenzeka kwenzeke.Ngalesi sikhathi, i-indoor I-ozone concentration ilula ukweqa izinga, elilimaza ngokuqondile impilo yabasebenzisi.

Uma uthenge umkhiqizo onobuchwepheshe be-electrostatic high-voltage (i-air purifier, isistimu yomoya omusha), lapho ngezinye izikhathi uzwa iphunga elincane le-fishy lapho ulisebenzisa, kufanele uqaphele ngalesi sikhathi, kungcono ukuvula iwindi. ukuze kungene umoya bese uyivala ngokushesha umkhiqizo.
