Chidule

Mfundo Zofunika Kwambiri

1. Mpweya wabwino wa miyezi 6 usanalowe umachotsa formaldehyde "yopanda" pamwamba.
2. Makabati amakono amagwira ntchito ngati "kapisozi yotulutsa pang'onopang'ono" chifukwa cha njira zochepa zofalitsira mankhwala mkati mwa utomoni wamatabwa.
3. Kutsegula mawindo nthawi zonse (kutsegula mawindo akamanunkhiza) sikuthandiza; kuletsa, kupitirira Kusinthana kwa Ndege ndikofunikira kuti pakhale chitetezo cha nthawi yayitali.

Bodza la Miyezi 6: N’chifukwa Chiyani Fungo Limabwerera?

Ndi njira yodziwika bwino ya eni nyumba atsopano: kumaliza kukonzanso, kutsegula mawindo onse, ndikulola nyumbayo "kupuma" kwa miyezi isanu ndi umodzi. Komabe, mabanja ambiri amanena kuti amadzuka ndi pakhosi louma komanso lokanda nthawi yoyamba yozizira, kapena kuona fungo la mankhwala likabweranso chilimwe chikafika.

Ngati nyumbayo inali ndi mpweya wokwanira, n’chifukwa chiyani formaldehyde imabwerera? Yankho lake lili mu kapangidwe ka mamolekyu a urea-formaldehyde resins omwe amagwiritsidwa ntchito popanga matabwa.

Monga katswiri wa HVAC wokhala ndi zaka 8 zokumana nazo pofufuza momwe mpweya ulili m'nyumba (IAQ), ndimaona izi tsiku ndi tsiku molakwika. Simukubwereranso ku mpweya woipa; mukukumana ndi zenizeni za momwe mpweya umatulutsira mpweya m'thupi kwa zaka zambiri.

Sayansi ya "Kapsule Yotulutsa Pang'onopang'ono"

Kupuma mpweya wabwino sikuthandiza kuthetsa vuto la kutulutsa kwa mankhwala kwa nthawi yayitali m'makabati amakono. Kuti timvetse chifukwa chake, tiyenera kuyang'ana momwe kufalikira kwa mpweya kumachitikira.

Kusanthula kwa SSA (Chiganizo, Ziwerengero, Kusanthula):

• Chiganizo: Kutentha ndi chinyezi cha nyengo zimakhudza kwambiri kuchuluka kwa utsi wa formaldehyde, zomwe zimapangitsa kuti mpweya wabwino ukhale wochepa kwakanthawi.

• Ziwerengero: Mayeso a chipinda cholamulidwa kuchokera ku Bungwe Lofufuza la Dziko Lonse la Canada (NRC) zikusonyeza kuti kuchuluka kwa formaldehyde komwe kumachitika nthawi zonse kumakhala kovuta kwambiri kumadera ang'onoang'ono amkati. Kusintha kuchokera pa 50% mpaka 80% ya chinyezi kungayambitse kubwereranso kwakukulu kwa mpweya wapoizoni.

• Kusanthula: Izi zikutsimikizira kuti formaldehyde imaphatikizidwa mu zomatira za mipando yanu. Monga momwe maphunziro aukadaulo amaphunzirira pa VOCs ochokera ku Yunivesite ya Texas Tech Monga momwe zikuwonekera, njira yofalitsira ndi ya zaka zambiri, ndipo imafalikira pang'onopang'ono. Kabati yanu imagwira ntchito ngati "kapisozi yotulutsa pang'onopang'ono," yomwe imafulumizitsa kutulutsa kwake poizoni nthawi yomweyo mukatseka mawindo anu kuti muyatse AC yachilimwe kapena kutentha kwa m'nyengo yozizira.

(Chithunzi A: Malo Oopsa - Kuchuluka kwa mpweya wochokera ku formaldehyde kumawonjezeka kwambiri ndi kutentha ndi chinyezi zomwe zimakwera kwambiri nyengo, zomwe zimagonjetsa zoyesayesa kwakanthawi zopumira mpweya.)

3. Zochitika Zenizeni Padziko Lonse: Deadzone ya Kabineti

Ngakhale chipinda chanu chochezera chitakhala "chotetezeka," ngozi yeniyeni ili pamene mpweya umasiya kuyenda.

Pa kafukufuku waposachedwa wa IAQ kwa kasitomala, mpweya wa m'chipinda chozungulira unayesedwa bwino mkati mwa malire a chitetezo. Komabe, malo ozungulira mkati mwa chipinda chogona chooneka ngati chopanda vuto, chotsekedwa, adapereka chithunzi chosiyana.

(Mayeso Oyesera: Chida chodziyesera chokha cha colorimetric chikuwonetsa kuchuluka kwa formaldehyde koopsa mkati mwa kabati yatsopano yotsekedwa, ngakhale kuti mpweya umalowa m'nyumba yonse.)

Zitseko za makabati zikatsekedwa, mpweya wamkati umaima. Kutuluka kwa mpweya kosalekeza m'makoma a matabwa, pamodzi ndi kusowa kwa mpweya wotuluka, kumapanga thumba la poizoni wambiri. Mukatsegula chitseko kuti mutenge chovala, mumakumana ndi VOC wambiri.

4. Yankho la Akatswiri: Airwoods Single Room ERV

Popeza kutulutsidwa kwa formaldehyde ndi njira ya zaka zambiri (yomwe imatenga zaka 3 mpaka 15), yankho silingakhale la kanthawi kochepa. Cholinga chachikulu cha kasamalidwe ka formaldehyde ndi kuletsa mwachangu, osati kuchotsa zinthu zomwe zawonongeka.

Apa ndi pomwe ukadaulo wapamwamba wa HVAC umalumikiza kusiyana. Kudalira mpweya wabwino wopanda mawindo sikusinthasintha ndipo kumawononga chitonthozo cha kutentha m'nyumba mwanu. Muyezo waukadaulo umayang'anira kukhazikitsa Chipinda Chokha cha Airwoods ERV (Kubwezeretsa Mphamvu Chopumulitsira mpweya (ventilator).

Chifukwa Chake Airwoods ERV Imapambana Mpweya Wopanda Mpweya:

• Kuchotsa Mosalekeza: Imachotsa mpweya wosasunthika, wolemera ngati VOC m'nyumba, ndikuuchotsa ku malo obisika monga makabati.

• Kugwiritsa Ntchito Mphamvu Moyenera: Mosiyana ndi zenera lotseguka lomwe limataya kutentha kapena kuziziritsa kwanu kokwera mtengo panja, ERV imapezanso mphamvu ya kutentha kuchokera mumlengalenga wotuluka ndikuyitumiza ku mpweya watsopano wolowa.

• Kukhazikika kwa Chilengedwe Chaching'ono: Mwa kugwira ntchito mosalekeza pa katundu wochepa, imasunga maziko okhazikika komanso otetezeka, kupewa kukwera kwa "kufalikira kochepa" komwe ofufuza a Texas Tech akuchenjeza za.

(Chithunzi B: Kusamalira Kosalekeza vs. Kupuma Mofulumira Kwakanthawi - Airwoods ERV imasunga kuchuluka kwa mpweya pansi pa malire a chitetezo cha WHO a 0.1 mg/m³, pomwe mpweya wobwerezabwereza umabweretsa kukwera koopsa kwa mpweya pamene mawindo atsekedwa.)

5. Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri)

Q: Kodi ma board a "E0" kapena "Zero-Formaldehyde" amachotsa chiopsezo chonse?
A: Ayi. Ngakhale kuti matabwa apamwamba amagwiritsa ntchito zomatira zotetezeka, "Zero-formaldehyde yowonjezera" sizikutanthauza kuti chinthu chomalizidwacho sichitulutsa ma VOC. Kusonkhanitsa zachilengedwe kuchokera ku mipando ingapo (chomwe chimapangitsa kuti zinthu ziyende bwino) kungathebe kukankhira chipinda chotsekedwa bwino kudutsa malire a chitetezo.

Q: Kodi ndingagwiritse ntchito matumba a carbon ogwiritsidwa ntchito m'makabati anga?
A: Kaboni yogwira ntchito ndi chinthu chomwe chimatenga mpweya nthawi zonse. Ikafika pamlingo wokwanira (nthawi zambiri mkati mwa milungu ingapo pamalo omwe mpweya umatulutsa kwambiri), imasiya kugwira ntchito ndipo imatha kutulutsa ma VOC mumlengalenga ngati kutentha kukukwera. Airwoods ERV imapereka njira yochotsera mpweya nthawi zonse.

Q: Kodi Airwoods Single Room ERV ndi yovuta kuyika m'nyumba yomwe yamalizidwa kale?
Yankho: Mosiyana ndi makina opopera mpweya a nyumba yonse, ma ERV a chipinda chimodzi adapangidwa kuti akonzedwenso. Amafunika kusintha pang'ono kapangidwe kake, zomwe zimapangitsa kuti akhale abwino kwambiri pa malo atsopano okonzedwanso omwe ali ndi mavuto a IAQ.
