Izindlu namuhla zilindele kakhulu izinto ezimbi. Sikhuluma ngamathuba njenge-VOCs ukusuka kumaphephethu nezixhobo zokucima eziphakeme abantu bazisebenzisa, i-mold spores ezivutha phakathi kwezimali eziphakeme, nezinkinga ezincane ezavela kumfuko wokudla noma ezahlukene kumoya wasekunene. Ukusebenza kakhulu kulezo mithombo kungadonsa kakhulu ubomi bethu. Abantu abaphila kuzindlu abangena umoya ongcono bafuna ukuthi izimo ze-asthma zakhelwe kabusha ngokuphindaphinda kanye ngokungu-30% kunazo ezinye izindlu ezenayo umoya. Kanti akuyona kuphela into yokugcina kwabomi bethu. Imbono yekholeji ibonisa uma amanzi aqhubeka ngaphezu kwe-1,000 parts per million kusindini sezindlu, imindeni ethu iyophula futhi. Ukugcina kokuthatha isigaba kusuke ngama-11% ngokwembono yaPHS Compliance eyakhiwe ngo-2023.

Indlela Umcinezelo Wokuvuseleka Ukwanda Kwesilinganiso Phansi Kuzindlu Ezinezindleko Eziphambene Nezimali

Amakhaya avalelwe ayethula imithuthuko kodwa ekupheleni kuyagcina izinkululeko zezulu eziphelele, ezakha ngaphakathi ngemvuselelo eyizigaba ezimbili ukuya ku-5 ngokusheshayo kungezindlu ezintandwayo. Lapho-ke ukuvikela kwezulu kusenza kube lula, kuguqula isivimba esiphansi phakathi ngezulu elisha emuva kokucubungula kuqala. Ngokwesiqephu esishicilelwe kwi-Gazeti Yokhuseleko Kwemali Engu-2024, uma lezi ziphatho zokuvikela kunezici zokuthola futhi umthubi, zilahlela izinto eziphazanyayo ezincane (PM2.5) ngamashumi amabili angu-66%, ngelinye ilanga ikhumbula amakhaya apholile kanye nokugcinwa kwabo kuhlanjelana. Akunakho dinga lokufaqa ukhokhelo ukuze uthole isivimba esihle.

Ukuvikela Kwezulu Ngendlela Elingcono Koma Ngendlela Yomshinelwa: Ukusebenza Kakhulu Emazingeni Amasha

Ukuvula izivivane ukuze kuthole amandla akamuva akamuva akunzulu kakhulu emakhaya apho igalagala kanye ngehlwempu yendiza zibangela ukuthi amandla akamuva akungafanelekile. Ngakho ke amakhaya manje anquma ukulandelana nezinhlelo zokuphindezela amandla ezintathu eziqashelwa ngu-ASHRAE. Lezi zinhlelo zizondla amandla ngokuphindaphinda kabusha ngamaxesha angama-0.35 ngexesha njengoko kusenzekile phandle. Umlando ophambili otholakeleyo ku-Anderson Air ubonisa futhi ukuthi le zinhlelo zibeka phansi izilinganiso ze-nitric oxide phakathi kwemikhumbi ngaproximately 40% kunjalo uma kusebenziswa izivivane evuliweyo kuphela. Lokhu kwenza uhlelo okubalulekile, ikakhulu emakhaya aphezulu apho ukulahlwa kwamandla akamuva akunzulu ngokweside.

Isifundo Sekholo: Ukwakha kwe-Khwalithi Yomoya Emakhayaweni Enezimali Eziningi

Ukuvuselelwa kwe-2023 kwe-Riverfront Tower yaseDenver—inkampu ephathekayo eqinileyo eqinile ngokwesivumelwano se-LEED—kubonisa ukuthi kanjani ukuthunyelwa kwezililo kufakelwe kakhulu emathunzini amahashi. Ngokuvuselela ukusebenza kwezinhlelo zokukhupha izililo ezihlangene nezixhumanisi ze-VOC, imithambo ivuselela izilimi zefomalethi ayide ngama-57% nakanti ibheke izimali zezililo ngama-22% (I-Lawrence Berkeley National Lab 2024).

Izinhlelo Zokukhupha Izililo: Ukudizaina Nokuthunyelwa Kuzenzakalo Ukuze Kutholakale Isililo Esibucayi

Izinhlobo zezinhlelo zokukhupha izililo kanye nezindlela zokusebenza

Izinhlelo zokukhupha izililo zamanje zisebenzisa umlando wokulila okudizainiwe ukuhlukanisa phansi kwezililo. Kunezinhlobo ezine eziphathelene kakhulu nokusebenzisa kwezifundaleni nasezindabeni:

1. Ukubuyisela Umthwalo (HRV) – Ubuyisela umthwalo phakathi kwezililo ezafika nezililo ezaphuma ekugcineni izimpande zezililo, njengoba zicimanga izimpande
2. Ukubuyisela Umthwalo Wemithwalo (ERV) – Yengeza ukuthwala kwe-humidity kumthwalo, okulinganiselwe kakhulu kumazulu abuhlungu
3. Ukuvula okulandelayo (DCV) – Ishintsha umlando wokulila ngokulinganisa izixhumanisi ze-CO₂/VOC
4. Izinhlelo Zokukhupha Ezentla – Susa izinkohlaka eziphakeme njengezindlu zokudla nezibhedele

Ngokwesithethelelo se-2023 soHlelo Lokuvila Kwamakhina, izinhlelo ze-HRV zibalisa kusukela ku-70% ukuya ku-95% wezimali zokugcwalisa ngelishwa ethuthile, ngemuva kokunakekela ukubanjwa kwamahawu. Izinhlelo ze-DCV zazidemonstrisa ukunciphisa kwezimali ku-40% embangweni wemigodi kunalokho okungeziwe (I-Journal ye-ASHRAE 2022).

Ukuthunyelana kwe-HVAC ngezinhlelo zokuvila ukugcinwa kwezimali zomoya phakathi ngendlela ethembekile

Ukuvilazayo okumangalisayo kuyangeni i-HVAC ngokusebenza ngendlela efanele:

• Izihlomelo zomoya zokuthola izinguquko zokuzulazula
• Izivalo ezihlukileyo ezilungiselela izilinganiso zomoya omusha
• Ukucaphuna okuphakeme okuchitha 99.97% yezinto ezingu-≈0.3¼m

Isahluko esandulelayo se-2024 sabona amabhunga ekhiphayo izimpilo eziphelele zokucaphuna kwe-MERV-13 ngezinhlelo ze-ERV zazicindezela izilinganiso ze-PM2.5 ngo-83% kunalokho okungeziwe. Ukuthunyelana okufanele kudinga ukubala:

Total Ventilation Load = (Occupant Demand – ACH) + (Building Pressure Differential – 0.05)  

Amastandiya e-ASHRAE namathuba afakiwe yokubanjwa kwamahawu abalulekile kumabhunga aphila

Izigaba ezikhona zafaka izilinganiso ezifanele zokubanjwa kwamahawu ukulawula izinkohlaka:

Isimo se-ASHRAE 62.2-2023 simelela izinguquko zomoya ngamazwe 0.35 ngamahora (ACH) njengobafla bempilo yasekhaya. Kodwa, ulwandiso lwe-EPA lubonisa ukuthi i-0.5 ACH libizisa izilinganiso ze-VOC ngo-37% kunalo xesha esingezansi.

Ukungcola kokudala kakhulu kwe-HVAC ngaphandle kwehlamvutho efanele

Izinhawu zonke ze-HVAC zibuyisela ngaphezu kuka-80% ukuya ku-90% yehlathi phakathi kwamakhaya, okwenzekayo kungahlanza kakhulu uma akukho hlamo efanele ekhona. Amakhaya angafuni izihlamo ezifanele zethulwa nge-58% kangcono abantu abathembeka ngemiphumela yokuphefha, futhi izinkampani zilahla ngaproximately amakhilogramu angu-740 ethola inyanga ngalinye ngalolu myalo njengoko kuchazwe nguPonemon Institute ngo-2023. Isisusa? Iziphathimandla zokunyanga ezigxilwe nezihlamo ze-HEPA noma okungenani izihlamo ezineqondo la-MERV-13 ziyishintsha konke. Lezi zinhawu zihlambalaza lonke ihlathi elisha eligodini kusuka kaphandle kuze kube yilapho kushintshwa ubude bokunyuka, ngakho akukho dala sihambise ihlathi elifuta.

Izinguquko Zehlathi: Ukuhlanza KokuNyanga Ukunciphisa Izici Ezivuthiwe

Ubuciko BekuHlathi Ukuthi Kuhlanza Kanjani Futhi Kusebenza Kanjani Ekunciphiseni Izici Evingiwe Phakathi Kwamakhaya

Isilinganiso sokuthi umoya wangaphandle usukwaphindaphinde kanjani umoya wangaphakathi kuyindlela ebalulekile ekuphazinyeni izinto ezithile njenge-VOCs nezinkinga zomoya zihlebeshwa phakathi. Kuzindlu ezibhekene ngokupheleleyo, ukugcina izinguquko zomoya phakathi kusuku esiphakade kusukela ku-0.35 kuze kube ngu-1.5 kubaluleke ekulungiseni ukuthi izinkunzi zingafinyelela amandla abalulekile okomphilo. Umdala ubonisa into ethandabuzwayo futhi - uma siphindaphinda lezi zinguquko zomoya, amandla we-formaldehyde ayenza ngaphezulu nge-40%, ngokwalesi ziphephandaba ze-ASHRAE ye-2022. Ngakho-ke kukhona njalo isivinini esihlukahlukene phakathi kumoya obuhle nomsebenzi owanele wokuvikela umoya.

Izinselelo Zinguquko Zomoya Ngesikhathi (ACH) Yezindlu, Izinkampani, Nezindawo Zokuhlondoloza Umphilo

Izinguquko ezide zomoya ezinhle kuzindawo zokuhlondoloza umphilo zifanisana nezinsiza ze-CDC zokukhinchela izifo ezakhelwa ngomoya, ngelishwa izilungiselelo zezindlu zizimise izindlela zokulahla umsebenzi.

Ukuvavanywa Okumelene: Ukusebenzisa I-Sensors Ukulungisa Ukuhambeka Kwe-Air Njengoba Kuyinxenye Yesikhathi Nezigaba Zokulinganiselwa Kwamandla

Iindawo ezintsha zihlangana ne-CO₂ sensors kunye ne-IoT technology ukulungisa ukuhambeka kwentliziyo ngendlela ebalulekileyo.
