Kungani Ukuba Isikhangeli Esihle Sokushisa Kumele Kuqoboza?

Indlela Isikhangeli Sokushisa Sibangela Ngayo Ubunzima Bokushisa Phakhathi Nokuphepha

Ukuziqonda Kwezixhobo Zokuphatha Amoya Ekugcineni Umoya Othile Ongcwele

Izixhobo zokuphatha amandla zisebenza njengeqondo elikhulu lokuphatha ubunzima bokulwa kwintlwini. Zisebenza ngokuthutha umoya futhi uvalele emacaleni ukuze acace izinto esidinga ukuphulula phansi. Xa umoya uphumelela kule cala ephambene kakhulu, kunciphisa konke okuchaza njengwehlathi, ipolena, nezinye izinto ezincane ezingaphakathi ezingathintwa ngabantu abanelwelwe ngezinkinga zokuhlala noma abaningi ngezinkinga zokuhlala. Ubunzima bezinto zize bekungekho kubonakala ngaphezu kwemboni yezinkampani ezintsha ezibekelwe ngempela ngaphandle kwezinto. Kwizindawo ezinjalo, umoya ongcolile uthamba kuphela ungasebenzi kakuhle, uzivuselela kumahluko angaba ngu-5 okwenzeka ngaphandle.

Izinkomba Ezijulile: Ukuzulazula Kwamafu, Ukucintisha, Nokudilutha Kwezimali Ezingatholakali

Izindlela ezintathu zibala indima yomkhandlu wamafu ekulondolozeni ububi bwegazi:

1. Ukuzulazula : Ukukhuthaza kwezindawo zegazi elingalunganga apho izimpande zamapfunga nezinhlayiya ezivuthayo ze-organic (VOCs) zihlala
2. Ukufinyelela : Ukubamba %90 yezinkinga ezincane njengama-0.3 microns ngemisindo ye-MERV 13+
3. Ukuhlambisana : Ukuvinjelisa igazi elitsha langaphandle ukuze libuyise igazi eliqinile langaphakathi

Lezi zinkomba zisebenza ngendlela ethunywa yizinye ukuze zifinyelele i-ASHRAE esithembisa utshintsho lwegazi ku-4–6 ngosuku emakhaya emphakethini, ukwethula imithombo yesifo egazini.

Indlela Ebophelelayo: Izimkhandlu Zegazi Ezinezimo Ngokushesha Ngenkathi Kuhlinjwe Ububi Bwegazi

Nakwemini, izinhlelo eziningi zasendulo zihlanganisa ne-IoT sensors ezingathola izinto njengezinkunkuma, amanzi aqhubekayo kwe-carbon dioxide, nokuthini komoya. Uma udibanisa lezi ziphazamiso ngezici ezithile ze-machine learning, kanti ke izixhumanisi zomoya ziqala ukusebenza ngokugcwele. Zizoba zakhupha ukuciphisa okuyinzuzo noma ukunyusa ukuvikela uma kubonwa ukuthi umoya ububi, ikakhulu ngalesi simo esihluphekile sokuphila kwamandla esiliva esisondzele ukuphila. Izindlu ezishiyene nalesi sihlalo sibona ukuba kukhula phansi kwe-18 kuze kube-32% izimpendulo ezivela kubantu bayengaphakathi ngokuthi bafuphile ngomoya ongcono. Umlayezo wokucwaninga osha kwemva kwezimali ezintembeka ezenziwa ngeminyaka engu-2023 uyashiselaya lokhu kahle.

Ukuciphisa Okuphelele: Ukususa Izici Ezibangela Ukuchithwa, Izici Ezibangela Inkohlakalo, Nezinkinga Eziphazanywayo Komoya

Ukudibanisa Kwe-HEPA Neziphazamiso Ze-Activated Carbon Kwi-Air Handlers

Lehlweni, izinhlayiya ezintsha zokuphatha amavili aziphumelela ngamafilteri aHEPA along with activated carbon layers ukulungisa konke okuchibiwe kumoya. I-HEPA ichaba ngaphezu kuka-99.97% kwezinkinga ezincane kusukela ku-0.3 microns njengoko pollen, izimpande zomuthi, ne-dust mites. Ngakwesikhathi esinye, i-activated carbon ichitha VOCs, izindlela ezimbi, nezilimi ezingaphambili eziqhubekayo phakathi kwendawo yethu yokuhlala. Ukudibanisa le ndlela zombili kufakazela konke okubonakalayo singabona nokungabonakali okuchithwa emoyeni wethu. Lokhu kusho isenzakalo xa sibuka idatha ya-2024 Indoor Air Quality Report eyaziwa ngokusayina ukuthi ukudityaniswa kwezinhlayiya ezahlukeneyo kuyindlela ephumelelayo ekuvuseleni umoya wesifazane.

Ukwefficiency kwezilawuli ze-UV nezinhliziyo eziningi zokuchitha izinto ezivutha

Ukusebenza kwe-technology ye-UV-C kuyisibonakaliso esihle kakhulu kumafiltari wamoya ngoba kusobala ukuthi kuhlukanisa i-DNA yezinhlayiya. Uma ihlanganiswa nezinhlelo ze-HEPA, lezi zinhlelo zingasusa izinhlayiya eziquqede amazinyo njengobacteria nezivirisi ngaphezu kwama-99.9%. Izinhlelo eziphambili zikhiqizwa ngemikhawulo engaphezu kweyodwa. Fikani okuqukethwe ngaphambi kwegumbi lokufa, emva koko liye kwi-HEPA, landela ngekhobhoni eqinephile ekayiphinde iphinde, futhi enze kube yilapho i-UV isetshenziswe. Konke lokhu kusebenza kahle kanye ukwakha isigaba esinamandla ekupheleleni izinto ezimbi eziquqede amazinyo. Isahluko sakugcina sekuqala kwelishwa lasekuseni selithole ukuthi abantu abasebenzisa lezi zinhlelo ezinezindima eziningi babona ukuthi imithombo yesifo yebhayi ibuka ngokubanzi ngemva kweyomnyaka. Kabanjwe abangu-3 ku-4 abaphathwayo babeka ukuthi baphila kahle uma izinhlelo ziqhubeka zihlaba izinhlayiya ezifana nezifo zebhayi ngokuchukwana kwezindlela ezahlukene zokuhamba kwamoya kumafilter.

Indlela Yedatha: U-EPA Usilinganisa Ukuthi Amazinyo Angaphakathi Ayaneleyo Ngaphezu Kwamazinyo Angaphandle Ngamashumi Amabili Kuya Ku-5

Umbiko wokhangelela kwezimali ngo-2023 we-EPA ubonisa ukuba kudingeka ukulungiselela okuphuthumayo: izindawo zasekhaya ziqukatha izilinganiso zezimali ezintathu kuya ku-5 ngaphezu kwezimali ezingaphandle njengoba kungabi khona ukuvikela kahle nokugcina kwamathambo. Lokhu kubonisa indima eyisisekelo yezixhobo zokukhangelela nezilungiselelo eziphakeme ekulungiseni izinkinga eziphila phansi ezihluku ngezono kanye nezempilo yentambo yesithelo.

Ukulungiselela Kwe-Humidity Nokulungiswa Kwemithambo: Ukulungiselela i-Mold, i-Bacteria, Namavi

Ukugcina amafutha aqondene (30–50%) olungeleyo lokholo lwentambo yesithelo

Abakhankani bezempilo bacesa ukugcina umthamo wamathambo esikhanyini phakathi kwe-30–50% ukuze bacine amathambo okuhlukunyisa kanye nokulungisa ukuthutha kwamathambo. Leli xabiso alivaleki ukugcina kwamathambo emboni yezixhobo zokukhangelela kanti nalokungavaleki ukuguqula kakhulu okungahlali kakhulu kuzo izifo ezibhalayo. Imboniso ibonisa ukuthi ukugcina leli xabiso kususa amathambo aphansi kusithelo ngaphezu kuka-60% kunazo ezingavikho (DryMax Restoration, 2023).

Indlela engalunganga yokulungiselela kwe-humidity ikhuthaza i-mold namathambo abalulekile

Umvuyiso ozungezile wokungcola kumelana ukuthi izizathu zomlambo zihlase ekhanda kwezinhlekele ze-HVAC bese zibiza izimvembelelo ezivuthiwe kumoya othunyelwayo. Izahluko zibonisa ukuthi amandla okungcola aphezulu kuka-60% ayahamba kakhulu isimo sokuphila kwamathambo ngaphezu kuka-400% ngaphakathi kwezinhlekele zomoya (Sanichem, 2023). Ukubuya kwezimali eziphakeme kwezinhlekele nezikhungo kwenza izindawo ezikhethekileyo zokugcina izilwane ezifana no Legionella .

Izilanga ze-UV nezicopho zokulima izilwane: Ukuze kube yisinkinga yokuphila kwamathambo eziqhathanisweni nomoya

Izinhlekele zomoya zamanje ziyambatha izilwane ngendlela eyizimbili eziphambili:

• Ukukhanya kwe-UV-C kumelela 99.9% yezivirasi nezilwane ezithunyelwayo
• Izicopho zokulima izilwane kwezikhungo zivikela ukuthi kweba i-biofilm kuzinhlangothi zokushintjana komthwalo

Lezi zixhumanisi zisebenza ngokuhlanganisa ukuze kube yisinkinga yokuhlukaniswa kwamathambo ngaphandle kokulahleka kwehlanzeko lokuthunyelwa komoya.

Isibonelo: Umkhondo wosifundazwe ubekwe phansi ukungabi khona emoyeni ngemuva kokucula izinhlekele zomoya

Indawo yasendleleni yaseMidwest yafundisa ukuba kukhula okuphelelwe kweziviko ezihlobene nesikhumba ngemva kokufaka izixhumanisi zomoya onikezwe UV nokusebenzisa ukucima kwamajaji ngokwesikhathi. Lokhu kulingana nezimangalo zeEPA evela kuthi izinhloso zokulungiswa kweHVAC zingakusa izilinganiso zezidlavu zomkhuhlane ngaphezulu kuka-71% (izimangalo zango-2023).

Ukusebenza Kwentonga: Ukuqinisekisa Ukudluliswa Kwe-Air Kuhlakanipha Nokukhuthaza Kokugcina

Ubukhulu Bekususa Kwe-Air Kuhlakanipha Ekukhuthazeni Kokugcinwa Kwezimali Esihlengalengane Ngaphandle

Ukuxhumana kwezulu kuhlinza izinto ezithi ngokuthi VOCs nezinkatho zedulayezulu ukuthi zikwazi kubekwa phakathi kwamakhaya. Indlela eyafuneka ngayo i-air handlers ibonakala yisimply kakhulu ngoba iyahlaba izulu ngapha kwezifiltro ukuze izinto ezimbi zithintwe futhi azizokwazi ukuhlala zihlambudhlile. Amakhanda afundela emehluko entutho entsha ethembekile ebekhona kakhona amandla okuhlaza izulu phakathi kwamakhaya ayengi-37% ngokusho kwezinhloso ezenziwe ngu-ASHRAE ngo-2023. Kuyakwenzeka uma ufaka uhlelo, izulu elihlanzekile alivamile kuphela kodwa kumele kuncike kuzindlela zempilo nokuphepha.

Isimo se-ASHRAE sibhalwe 62.1 nesiqiniseko sobunjalo besilungiso sezingqalasuku zezimali

Isimo se-ASHRAE sibhalwe 62.1 sibala ubuningi obuncane besilungiso sokuxhumana kwezulu ukuhlinza ubunzima bezulu phakathi kwamakhaya–ngokuvamile 5–10 ukuguquka kwezulu ngosuku olunye kuzinkinga zezimali. Ukulandela lezi ziqiniseko kusihlinza ukuba kube khona okufanayo kwe-oksijini futhi kususa izulu elidala, lokhu kumele kuncike kuzinkinga ezithile njengezindlu zokugcina nezinsukwane apho ukuthi kuchitheke kwe-CO₂ kungahlinza indlela isinqumo esiphatha.

Ukumisela: Ukuvuselelwa Kwezimali Kudidekayo Nokuthunyelwa Kwizimali Ngokuchazwe

Izimali ezintsha ziyasebenzisa ukuvuselelwa kwezimali kudidekayo ukuze kubekwe izilinganiso ngokwesimo sezimali noma imikhuba yobomi bezimali. Le ndlela ibe yenza ukuba kuncaneke isenzo ngakithi 45%kulingana nezimali eziphathelene, ngelinye nokugcina ubomi bempilo.

Inkinga: Ukuthuthuka Kwezempilo Kudingekayo Ngokungahambi Kwezimali Zokuvuselelwa Kwizimali

Ukungavuseleli kahle kwenza kube yinto ethi "ibhuldging elihluphekileyo," enenjalo njenge-"headaches" nezimbono zokugula kuzakha ku 23% yezisebenzi zegumbi (NIOSH 2023). Isahluko esisha sabona amathuluzi athuthukiswayo ekuvuseleleni kwizimali kakhulu ayibonisa ukuncipha ngokushesha kwezimbono zokuhlwa ngamazinyo ngokushesha kwezimali ngokushesha ukuncipha okuqukethwe kwezimbono zokuhlwa ngamazinyo ngaphansi kwe-31% , kubonisa izinkinga zempilo zendlela yokugula kwezimali.

Iziphawu Zempilo Nokulungiswa: Ukuqhathanisa Ukulungiswa Kwizimali Nezempilo Ezidlule

Imiphumela Yobuhlobo Ngokungahle Kobuhlobo Bwezulu: Ukuchaphazeka, I-Asthma, Nokugcina Kwintando
