Popeza kuti malamulo atsopano omangira amachititsa kuti maenvulopu omangirira azikhala olimba, nyumba zimafunikira njira zamakina zopumira mpweya kuti mpweya wamkati ukhale wabwino.
Yankho losavuta pamutu wankhani ino ndi aliyense (munthu kapena nyama) wokhala ndikugwira ntchito m'nyumba. Funso lalikulu ndilakuti timapanga bwanji kuti tipereke mpweya wabwino wokwanira wokhala ndi okosijeni womanga anthu okhalamo kwinaku tikuchepetsa kugwiritsa ntchito mphamvu kwa HVAC molingana ndi malamulo aboma apano.
Mpweya Wotani?
Ndi maenvulopu omangika amasiku ano tiyenera kuganizira momwe tingayambitsire mpweya mkati ndi chifukwa chake. Ndipo tingafune mitundu ingapo ya mpweya. Nthawi zambiri pamakhala mtundu umodzi wokha wa mpweya, koma mkati mwa nyumba timafunikira mpweya kuti tichite zinthu zosiyanasiyana malinga ndi ntchito zathu zamkati.
Mpweya wolowera mpweya ndi wofunika kwambiri kwa anthu ndi nyama. Anthu amatha kupuma ma 30 lbs. mpweya tsiku lililonse pamene timathera pafupifupi 90% ya moyo wathu m'nyumba. Pa nthawi yomweyo, m`pofunika kuchotsa owonjezera chinyezi, fungo, carbon dioxide, ozoni, particulates ndi zina zoipa mankhwala. Ndipo pamene kutsegula zenera kumapereka mpweya wofunikira, mpweya wabwinowu umapangitsa makina a HVAC kugwiritsa ntchito mphamvu zambiri zomwe tikuyenera kupulumutsa.
Makina Olowera mpweya
Nyumba zamakono ndi nyumba zamalonda zimayang'anitsitsa kwambiri mpweya ndi chinyezi zomwe zimalowa mkati kapena kunja kwa nyumbayo, ndipo ndi miyezo monga LEED, Passive House ndi Net Zero, nyumba zimakhala zolimba ndipo envelopu yomangayo imasindikizidwa ndi cholinga chotuluka mpweya. osapitirira 1ACH50 (kusintha kwa mpweya kumodzi pa ola pa 50 pascals). Ndawonapo mlangizi m'modzi wa Passive House akudzitamandira 0.14ACH50.
Ndipo makina amakono a HVAC amapangidwa bwino ndi ng'anjo za gasi ndi zotenthetsera madzi pogwiritsa ntchito mpweya wakunja kuti uyake, ndiye moyo ndi wabwino, ayi? Mwina sizili bwino, popeza tikuwonabe malamulo a chala chachikulu akuzungulira makamaka pantchito zokonzanso pomwe makina olowera mpweya nthawi zambiri amakhala okulirapo, ndipo ma hood amphamvu amatha kuyamwa pafupifupi mamolekyu onse a mpweya kunja kwa nyumba kukakamiza omwe angakhale ophika kuti atsegule. zenera.
Kuyambitsa HRV ndi ERV
Makina opangira mpweya wabwino (HRV) ndi njira yolowera mpweya yomwe imagwiritsa ntchito mpweya wotayira wotayira kuti utenthetsenso kuzizira komweko kolowera kunja kwa mpweya wabwino.
Pamene mitsinje ya mpweya imadutsana mkati mwa HRV, kupitirira 75% kapena kuposapo kutentha kwa mpweya wamkati kudzasamutsidwa ku mpweya wozizira kwambiri motero kumapereka mpweya wofunikira pamene kuchepetsa mtengo wa "kupanga" kutentha komwe kumafunika kubweretsa. mpweya wabwino mpaka kuchipinda chozungulira.
M'malo achinyezi, m'miyezi yachilimwe HRV imachulukitsa kuchuluka kwa chinyezi m'nyumba. Nyumba yozizirirapo ikugwira ntchito komanso mawindo otsekedwa, nyumbayo imafunikirabe mpweya wokwanira. Dongosolo lozizirira lokhala ndi kakulidwe koyenera kopangidwa poganizira za kutentha kwanthawi yachilimwe liyenera kuthana ndi chinyezi chowonjezera, zovomerezeka, pamtengo wowonjezera.
ERV, kapena mpweya wobwezeretsa mphamvu, umagwira ntchito mofanana ndi HRV, koma m'nyengo yozizira chinyezi china cha mumlengalenga chimabwerera kumalo amkati. M'malo mwake, m'nyumba zothina, ERV imathandizira kusunga chinyezi chamkati mwa 40% polimbana ndi zovuta komanso zoyipa za mpweya wouma wa nthawi yachisanu.
Opaleshoni yachilimwe yapangitsa ERV kukana pafupifupi 70% ya chinyezi chomwe chikubwera chomwe chimachitumiza kunja chisanalowetse makina ozizirira. ERV sichita ngati dehumidifier.
Ma ERV Ndiabwino Panyengo Yachinyezi
Malingaliro oyika
Ngakhale mayunitsi a ERV/HRV opangidwira kukhazikitsidwa kwa nyumba zogona amatha kukhazikitsidwa m'njira yosavuta kugwiritsa ntchito makina owongolera mpweya omwe alipo kuti agawire mpweya wokhazikika, musachite mwanjira imeneyi ngati nkotheka.
M'malingaliro anga, ndikwabwino kukhazikitsa njira yodzipatulira yodzipereka pantchito zomanga zatsopano kapena kukonzanso komaliza. Nyumbayo idzapindula ndi kugawa kwa mpweya wabwino kwambiri komanso mtengo wotsika kwambiri, popeza ng'anjo kapena chowongolera mpweya sichidzafunika. Nachi Chitsanzo cha kukhazikitsa kwa HRV ndi ntchito yolowera mwachindunji. (gwero: NRCan Publication (2012): Othandizira Kubwezeretsa Kutentha)
