Kutheni iinyanga ezi-6 zokungenisa umoya zinganelanga: Inyaniso efihliweyo malunga neFormaldehyde kwizindlu ezintsha

Umbhali: [Alex/Airwoods], i-HVAC kunye neNgcali yoMgangatho woMoya wangaphakathi (Amava eminyaka esi-8)
Idatha: Idatha yeSayensi ixhaswa yi-NRC Canada kunye neTexas Tech University

Isishwankathelo

Izinto ezibalulekileyo ekufuneka ziqwalaselwe

1. Umoya oqhelekileyo weenyanga ezi-6 ngaphambi kokungena ususa kuphela i-formaldehyde "engenamphezulu" ekumgangatho ophezulu.
2. Iikhabhathi zanamhlanje zisebenza njenge "capsule ekhulula kancinci" ngenxa yeenkqubo zeekhemikhali ezinqongopheleyo zokusasazeka ngaphakathi kwiiresini zomthi.
3. Umoya osebenzayo (ukuvula iifestile xa kunuka) awusebenzi; uyasebenza, uyaqhubeka Utshintshiselwano loMoya iyadingeka ukuze kugcinwe amanqanaba akhuselekileyo exesha elide.

Intsomi Yeenyanga Ezi-6: Kutheni Ivumba Libuya?

Yinkqubo eqhelekileyo kubanini bezindlu abatsha: gqibani uhlaziyo, vulani zonke iifestile, nize nivumele indlu "iphefumle" iinyanga ezintandathu. Nangona kunjalo, iintsapho ezininzi zibika ukuba zivuka zinomqala owomileyo nokrwela ngexesha lasebusika bazo bokuqala, okanye nibone ukubuya kwevumba elibi lekhemikhali xa kufika ihlobo.

Ukuba indlu yayinomoya opheleleyo, kutheni i-formaldehyde ibuya? Impendulo ikwisakhiwo semolekyuli se-urea-formaldehyde resins ezisetyenziswa kwimithi eyenziweyo.

Njengengcali ye-HVAC eneminyaka esi-8 yamava okuhlalutya imeko-bume yomgangatho womoya wangaphakathi (IAQ), ndibona le ngcamango iphosakeleyo imihla ngemihla. Awunawo "ukubuyela umva" komgangatho womoya ombi; ufumana inyani yeprofayili yokukhupha umoya iminyaka emininzi.

Isayensi ye "Slow-Release Capsule"

Umoya oqhelekileyo awukwazi ukujongana nemeko yokukhutshwa kweekhemikhali ixesha elide kwiikhabhinethi zanamhlanje. Ukuze siqonde isizathu, kufuneka sijonge indlela ezisasazeka ngayo.

Uhlalutyo lwe-SSA (Ingxelo, Izibalo, Uhlalutyo):

• Ingxelo: Ubushushu kunye nokufuma kwexesha elithile kuchaphazela kakhulu amazinga okukhupha i-formaldehyde, nto leyo eyenza ukuba umoya oqhelekileyo ube yi-band-aid yexeshana.

• Izibalo: Uvavanyo lwegumbi elilawulwayo oluvela kwi IBhunga loPhando leSizwe laseKhanada (i-NRC) ibonisa ukuba amazinga e-formaldehyde ahlala ezinzile abuthathaka kakhulu kwiindawo ezincinci zangaphakathi. Utshintsho ukusuka kwi-50% ukuya kwi-80% yomswakama ohambelanayo lunokubangela ukuphinda kuvele amanqanaba egesi enobuthi.

• Uhlalutyo: Oku kuqinisekisa ukuba i-formaldehyde idityaniswe ngokwesakhiwo kwizincamathelisi zefenitshala yakho. Njengoko uphando lwezemfundo kwi-VOCs oluvela IYunivesithi yaseTexas Tech icebisa ukuba, inkqubo yokusasazwa kwezixhobo ithatha iminyaka emininzi, i-kinetic enomda wokusasazwa kwezixhobo. I-wardrobe yakho isebenza njenge-"capsule ekhupha kancinci," ikhawulezisa imveliso yayo enobuthi xa uvala iifestile zakho ukuze uvule i-AC yasehlotyeni okanye ubushushu basebusika.

(Umfanekiso A: Indawo Eyingozi - Amanqanaba okukhupha i-formaldehyde alandela ngamandla ngokunyuka kwamaqondo obushushu kunye nokufuma kwexesha elithile, oyisa imizamo yokungenisa umoya okwethutyana.)

3. Amava eHlabathi lokwenyani: Indawo yokuGqibela yeKhabhinethi

Nokuba igumbi lakho lokuhlala libonakala "likhuselekile," ingozi yokwenyani ilapho umoya uyeka khona ukuhamba.

Ngexesha lovavanyo lwakutshanje lwe-IAQ kumthengi, umoya wegumbi elingaphakathi uvavanywe kakuhle ngaphakathi kwemida yokhuseleko. Nangona kunjalo, imeko-bume yangaphakathi yekhabhathi yegumbi lokulala ebonakala ingenatyala, ivaliwe iveze umfanekiso owahlukileyo.

(Uvavanyo lwasentsimini: Ikhithi yokuzivavanya esemgangathweni yemibala ebonisa amazinga aphezulu e-formaldehyde ngaphakathi kwekhabhathi esandul’ ukufakwa, evaliweyo, nangona kukho umoya ophumayo endlwini yonke.)

Xa iingcango zeekhabhathi zivaliwe, umoya wangaphakathi uyama. Ukuchitheka kwegesi rhoqo kwiiphaneli zomthi, kunye nokungabikho komoya, kudala ipokotho enobuthi obuxineneyo. Wakuvula ucango ukuze uthathe ijazi, ufumana idosi exineneyo yeeVOC.

4. Isisombululo soBugcisa: I-Airwoods Single Room ERV

Ekubeni ukukhutshwa kwe-formaldehyde kuyinkqubo yeminyaka emininzi (ethatha iminyaka emi-3 ukuya kweli-15), isisombululo asinakuba sesexeshana. Eyona nto iphambili ekulawulweni kwe-formaldehyde kukunciphisa i-proactive, kungekhona ukukhupha i-reactivity.

Kulapho ubuchwepheshe be-HVAC obuphucukileyo buvala khona umsantsa. Ukuthembela kumoya ongenamsebenzi kwiifestile akuqhelekanga kwaye kuyayiphazamisa intuthuzelo yobushushu bekhaya lakho. Umgangatho wobungcali ulawula ukusetyenziswa kwe- I-Airwoods Igumbi Elinye I-ERV (Ukubuyiselwa kwamandla Isixhobo sokungenisa umoya).

Kutheni i-Airwoods ERV iphumelela kwi-Passive Ventilation:

• Ukukhupha rhoqo: Ikhupha umoya omileyo, onzima njenge-VOC ngaphandle kwekhaya, iwususa kwiindawo ezimnyama ezifana neekhabhathi.

• Ukonga Amandla: Ngokungafaniyo nefestile evulekileyo ekhupha ubushushu okanye ukupholisa kwakho okubizayo ngaphandle, i-ERV ifumana amandla obushushu emoyeni ophumayo ize iwadlulisele emoyeni omtsha ongenayo.

• Uzinzo lweNdalo encinci: Ngokusebenza ngokuqhubekayo kumthwalo ophantsi, igcina isiseko esizinzileyo nesikhuselekileyo, ithintela ukwakheka "okulinganiselweyo kokusasazwa" okulumkisa ngako abaphandi beTexas Tech.

(Umfanekiso B: Ulawulo Oluqhubekayo vs. Umoya Owexeshana - I-Airwoods ERV igcina umlinganiselo ongaphantsi kakhulu komda wokhuseleko lwe-WHO we-0.1 mg/m³, ngelixa umoya ophendulayo ubangela ukunyuka koxinzelelo oluyingozi xa iifestile zivaliwe.)

5. Imibuzo Ebuzwa Rhoqo (Ii-FAQ)

Q: Ngaba iibhodi ze-"E0" okanye ze-"Zero-Formaldehyde" ziyawususa ngokupheleleyo umngcipheko?
A: Hayi. Nangona iibhodi ezikumgangatho ophezulu zisebenzisa izincamathelisi ezikhuselekileyo, "i-Zero-formaldehyde eyongeziweyo" ayithethi ukuba imveliso egqityiweyo ayikhuphi zi-VOC. Ukuqokelelwa kwendalo okuvela kwiifenitshala ezininzi (into yokulayisha) kusenokubangela ukuba igumbi livalwe ngokuqinileyo lidlule umda wokhuseleko.

Q: Ndingasebenzisa nje iingxowa zekhabhoni ezivuselelweyo kwiikhabhathi zam?
A: Ikhabhoni esebenzayo yi-absorbent engasebenziyo. Yakuba ifikelele kubunzulu (ngokuqhelekileyo kwiiveki ezimbalwa kwindawo enokukhupha ukungcola okuphezulu), iyayeka ukusebenza kwaye inokukhupha ii-VOC emoyeni kwakhona ukuba amaqondo obushushu ayaphakama. I-Airwoods ERV inika ukususwa okusebenzayo nokuqhubekayo.

Q: Ingaba i-Airwoods Single Room ERV kunzima ukuyifaka kwikhaya esele ligqityiwe?
A: Ngokungafaniyo neenkqubo zemibhobho yendlu yonke, ii-ERV zegumbi elinye zenzelwe ukulungiswa kwakhona. Zifuna uhlengahlengiso oluncinci lwesakhiwo, nto leyo ezenza zibe lolona phuculo lufanelekileyo kwiindawo ezisandula ukuhlaziywa ezinengxaki ze-IAQ.
