Zifukwa Zazikulu Zoyambitsa Mavuto a Mphepo Yamkati

Zinthu zoipitsa mpweya m'nyumba zomwe zimatulutsa mpweya kapena tinthu ting'onoting'ono mumlengalenga ndiye chifukwa chachikulu cha mavuto a mpweya m'nyumba. Kusakwanira mpweya wabwino kungawonjezere kuchuluka kwa zinthu zoipitsa mpweya m'nyumba mwa kusabweretsa mpweya wokwanira wakunja kuti uchepetse mpweya wochokera m'nyumba komanso mwa kusatulutsa zinthu zoipitsa mpweya m'nyumba m'deralo. Kutentha kwambiri ndi chinyezi zingawonjezere kuchuluka kwa zinthu zina zoipitsa mpweya.

Magwero Oipitsa

Pali zinthu zambiri zomwe zimayambitsa kuipitsidwa kwa mpweya m'nyumba. Izi zitha kuphatikizapo:

• Zipangizo zoyatsira moto zoyatsira mafuta
• Fodya
• Zipangizo zomangira ndi mipando yosiyanasiyana monga:
  • Kuteteza kutentha komwe kuli ndi asbestos komwe kwawonongeka
  • Pansi, mipando kapena kapeti yoyikidwa kumene
  • Makabati kapena mipando yopangidwa ndi zinthu zina zamatabwa osindikizidwa
• Zinthu zoyeretsera ndi kukonza zinthu m'nyumba, zosamalira munthu payekha, kapena zosangalatsa
• Makina otenthetsera ndi kuziziritsa apakati ndi zipangizo zotenthetsera chinyezi
• Chinyezi chochuluka
• Zinthu zakunja monga:
  • Radoni
  • Mankhwala ophera tizilombo
  • Kuipitsa mpweya wakunja.

Kufunika kwa gwero lililonse kumadalira kuchuluka kwa zinthu zoipitsa zomwe zimatulutsa komanso kuchuluka kwa mpweya umene umatulutsawo. Nthawi zina, zinthu monga zaka zomwe gwerolo lili nazo komanso ngati silikusamalidwa bwino ndizofunikira kwambiri. Mwachitsanzo, chitofu cha gasi chosasinthidwa bwino chingatulutse mpweya wambiri wa carbon monoxide kuposa chomwe chasinthidwa bwino.

Magwero ena, monga zipangizo zomangira, mipando ndi zinthu monga zotsukira mpweya, amatha kutulutsa zinthu zoipitsa mpweya nthawi zonse. Magwero ena, okhudzana ndi zochita monga kusuta fodya, kuyeretsa, kukongoletsanso kapena kuchita zinthu zosangalatsa, amatulutsa zinthu zoipitsa mpweya nthawi ndi nthawi. Zipangizo zosagwira ntchito bwino kapena zinthu zosagwiritsidwa ntchito bwino zimatha kutulutsa zinthu zoipitsa mpweya m'nyumba zomwe nthawi zina zimakhala zoopsa.

Kuchuluka kwa zinthu zodetsa kungathe kukhalabe mumlengalenga kwa nthawi yayitali pambuyo pa zochita zina.

Dziwani zambiri zokhudza kuipitsa mpweya m'nyumba ndi magwero a:

• Asbesto
• Zinthu Zoipitsa Zamoyo
• Mpweya wa Monoxide (CO2)
• Zogulitsa za Formaldehyde/Pressed Wood
• Mtsogoleli (Pb)
• Nayitrogeni Dioxide (NO2)
• Mankhwala ophera tizilombo
• Radon (Rn)
• Zinthu Zamkati Zamkati
• Utsi wa Fodya Wogwiritsidwa Ntchito ndi Munthu Wina/ Utsi wa Fodya Woteteza Kuchilengedwe
• Masitovu ndi Zotenthetsera
• Malo Ozimitsira Moto ndi Chimney
• Ma Volatile Organic Compounds (VOCs)

Mpweya wosakwanira

Ngati mpweya wakunja wochepa kwambiri ulowa m'nyumba, zinthu zoipitsa mpweya zimatha kusonkhana mpaka kufika pamlingo womwe ungayambitse mavuto azaumoyo komanso chitonthozo. Pokhapokha ngati nyumba zamangidwa ndi njira zapadera zopumira mpweya, zomwe zapangidwa kuti zichepetse mpweya wakunja womwe ungatuluke ndi kutuluka zitha kukhala ndi zinthu zambiri zoipitsa mpweya m'nyumba.

Momwe Mpweya Wakunja Umalowera M'nyumba

Mpweya wakunja ukhoza kulowa ndi kutuluka mnyumba mwa: kulowa mkati, mpweya wachilengedwe, ndi mpweya wamakina. Mu njira yotchedwa kulowa mkati, mpweya wakunja umalowa mnyumba kudzera m'mabowo, malo olumikizirana, ndi ming'alu m'makoma, pansi, ndi padenga, komanso mozungulira mawindo ndi zitseko. Mu mpweya wachilengedwe, mpweya umayenda kudzera m'mawindo ndi zitseko zotseguka. Kuyenda kwa mpweya komwe kumakhudzana ndi kulowa mkati ndi mpweya wachilengedwe kumachitika chifukwa cha kusiyana kwa kutentha kwa mpweya pakati pa nyumba ndi panja komanso ndi mphepo. Pomaliza, pali zida zingapo zopumira mpweya, kuyambira mafani otulutsa mpweya wakunja omwe amachotsa mpweya mchipinda chimodzi nthawi ndi nthawi, monga zimbudzi ndi khitchini, mpaka machitidwe ogwiritsira ntchito mpweya omwe amagwiritsa ntchito mafani ndi ntchito zama ducts kuti achotse mpweya wamkati mosalekeza ndikugawa mpweya wosefedwa komanso wokonzedwa bwino kupita kumalo ofunikira mnyumba yonse. Kuthamanga komwe mpweya wakunja umalowa m'malo mwa mpweya wamkati kumafotokozedwa ngati kuchuluka kwa kusinthana kwa mpweya. Pakakhala kulowerera pang'ono, mpweya wachilengedwe, kapena mpweya wamakina, kuchuluka kwa kusinthana kwa mpweya kumakhala kochepa ndipo kuchuluka kwa zinthu zoipitsa mpweya kumatha kuwonjezeka.
