Popeza kuti malamulo atsopano omangira amatsogolera kuti maenvulopu omangirira azikhala olimba, nyumba zimafunikira njira zolowera mpweya wamakina kuti mpweya wamkati ukhale wabwino.
Yankho losavuta pamutu wankhani ino ndi aliyense (munthu kapena nyama) wokhala ndikugwira ntchito m'nyumba.Funso lalikulu ndilakuti timachita bwanji kupereka mpweya wabwino wokwanira wokhala ndi okosijeni womanga anthu okhalamo ndikusungabe mphamvu zochepetsera mphamvu za HVAC monga momwe zakhazikitsira malamulo aboma.
Molimbikitsidwa ndi kugwa kwa chiletso chamafuta koyambirira kwa zaka za m'ma 1970, dipatimenti ya Zamagetsi ku US (DOE) idayamba pulogalamu yoteteza mphamvu zonse zomwe zidapangitsa kuti olamulira aku North America akhazikitse miyezo yowonjezereka ya HVAC kapena Minimum Efficiency Performance Standards. (MEPS).
Pamodzi ndi zida za HVAC zogwiritsa ntchito mphamvu zambiri zomwe zapangitsa kuti nyumba zitsekedwe molimba momwe zingathere ndi mazenera othina, zitseko, zotchingira mpweya ndi zitini zokulitsa thovu.
Pakafukufuku wina wa kukonzanso kwa malo okhala m'zaka za m'ma 90, nyumba yomwe ikufunsidwayo idakhumudwitsidwa kupitilira ma pascals 50 pomwe zida zonse zotopetsa mpweya (mafani aku bafa, ma khitchini osiyanasiyana) anali kuyenda.Ndiko kupsinjika kochulukirapo ka 10 kuposa momwe amaloledwa, makamaka ndi zida zopangira mafuta opangira mpweya mkati mwa kapangidwe kake.Tikufuna mpweya!
Mpweya Wotani?
Ndi maenvulopu omangika masiku 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 mankhwala ena oopsa.Ndipo pamene kutsegula zenera kumapereka mpweya wofunikira, mpweya wabwinowu umapangitsa makina a HVAC kugwiritsa ntchito mphamvu zambiri zomwe tikuyenera kupulumutsa.
Mpweya wodzipangira okha ndi mpweya womwe umachokera kunja womwe umafuna kuti ulowe m'malo mwa mpweya umene watopa ndi zipangizo monga ma hoods ndi mafani a bafa, makina apakati a vacuum ndi zowumitsira zovala.Nyumba zamasiku ano zomangidwa molingana ndi ma code aposachedwa mwina sizifunanso mpweya wodzikongoletsera pokhapokha ngati ma hood okulirapo omwe amasuntha mpweya waukulu (opitilira 200 cfm) ayikidwa ndi ophika okangalika.
Potsirizira pake, palinso mpweya woyaka, mpweya womwe umatanthawuza kugwiritsidwa ntchito ndi zida zopangira mafuta monga ng'anjo za gasi, zotenthetsera madzi, masitovu ndi nkhuni zoyaka moto.Podzaza mpata uliwonse wa mpweya wotuluka m'nyumba zamasiku ano, zida za gasi ziyenera "kubwereka" mpweya wolowera mpweya motero zimabweretsa vuto lowopsa.Zida zomwe sizitha kutuluka chifukwa cha kupsinjika maganizo, kapena njala ya mpweya, zikhoza kuyamba kuwotcha zinthu zawo zomwe zimapangitsa kuti carbon monoxide iwonongeke, tsoka lomwe lathetsa miyoyo ya anthu ambiri kwa zaka zambiri.
KuyambitsaHRVndiERV
Nyumba zakale zinali zotayikira kotero kuti mpweya wolowera unkakwaniritsa zofunikira zonse zolowera mpweya mosavuta, koma popanda zilango.Mpweya wobwera unkafunika kutenthedwa ndi kutentha ndipo mwina chinyontho chomwe chimabweretsa ndalama zina zogulira mafuta ndi kukonza.Nyumbazo zinali zamphepo, anthu okhalamo nthawi zambiri amakhala osamasuka chifukwa mpweya wouma umatulutsa chinyezi chambiri kuchokera pakhungu ndikupangitsa kumva kuzizira kwambiri.Kumangika kwa magetsi osasunthika m'makapeti ndi mipando kudadzetsa mantha opweteka pamene mwini nyumba wamagetsi adakhudza pansi.Kotero, chabwino nchiyani?
Mpweya wotsitsimula kutentha (HRV) ndi njira yopangira mpweya wabwino yomwe idzagwiritse ntchito mpweya wotayira wotayirira kuti utenthetsenso kuzizira komweko kolowera kunja kwa mpweya wabwino.
Pamene ma airstream amadutsana mkati mwa HRV, kupitirira 75% kapena kuposapo kutentha kwa mpweya wamkati kudzasamutsidwa ku mpweya wozizira kwambiri motero kupereka mpweya wofunikira pamene kuchepetsa mtengo wa "kupanga" kutentha komwe kumafunika kubweretsa. mpweya wabwino mpaka kutentha kwa chipinda.
M'malo achinyezi, m'miyezi yachilimwe HRV imachulukitsa kuchuluka kwa chinyezi m'nyumba.Nyumba yozizirirapo ikugwira ntchito ndipo mawindo atsekedwa, nyumbayo imafunikabe mpweya wokwanira.Dongosolo lozizirira lokhala ndi kakulidwe koyenera kopangidwa poganizira za chilimwe latent load liyenera kuthana ndi chinyezi chowonjezera, zovomerezeka, pamtengo wowonjezera.
Mpweya wotsitsimula mphamvu (ERV), 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 chisanatsegule makina ozizirira.ERV sichita ngati dehumidifier.
Ma ERV Ndiabwino Panyengo Yachinyezi
Akatswiri a mpweya wabwino adzanena kuti mpweya wabwino wa makina panyumba iliyonse umadalira nyengo, moyo wa anthu okhalamo komanso zosowa za mwiniwake.Mwachitsanzo, m'nyumba momwe chinyezi chimakwera pamwamba pa 55%, HRV ingachite bwino kuchotsa chinyezi chochulukirapo.
Akatswiri amavomerezanso kuti nyumba zatsopano, kapena zomwe zakonzedwanso kukhala zomanga zatsopano, ziyenera kukhala ndi ERV yotchulidwa chifukwa nyumba zomwe zili ndi mazenera owala katatu komanso zipinda zapansi zotetezedwa bwino zimatha kukhala ndi chinyezi chambiri m'miyezi yozizira: 35% +/- 5% ndizovomerezeka.
Chitsanzo cha chithunzi cha HRV choyikidwa ndi makina opangira ng'anjo ya mpweya.(gwero:NRCan Publication (2012):Zothandizira Kubwezeretsa Kutentha)
Malingaliro oyika
Ngakhale mayunitsi a ERV/HRV opangidwa kuti aziyika nyumba zogona amatha kuyikidwa m'njira yosavuta kugwiritsa ntchito makina owongolera mpweya omwe alipo kuti agawire mpweya wokhazikika, musachite mwanjira imeneyi ngati nkotheka.
M'malingaliro anga, ndikwabwino kukhazikitsa makina odzipatulira odzipereka 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.
Zina mwa zida zabwino kwambiri za HRV/ERV pamsika zimakhala ndi ma motors a EC ndikuwongolera ma aligorivimu omwe amatha kusanja makinawo ndikusintha kuti asinthe.
Zingatenge nthawi kuti atsimikizire eni nyumba onse kuti mpweya wabwino wa makina ndi wapamwamba kwambiri kuposa kutsegula mazenera nthawi iliyonse.Anthu akumatauni alidi ndi chidwi chodalira mpweya wabwino wokhazikika komanso wosamalidwa bwino, monga momwe kafukufuku akusonyezera, sanakhalepo nawo.
Chitsanzo cha kukhazikitsa kwa HRV ndi ma ductwork mwachindunji.(gwero:NRCan Publication (2012):Zothandizira Kubwezeretsa Kutentha)
Holtop ndi wopanga kutsogolera China okhazikika kupanga mpweya ndi mpweya kuchira kuchira equipments.Imaperekedwa ku kafukufuku ndi chitukuko cha teknoloji m'munda wa mpweya wobwezeretsa kutentha ndi mphamvu zopulumutsa mphamvu zothandizira mpweya kuyambira 2002. Zinthu zazikuluzikulu zikuphatikizapo mpweya wotsitsimula ERV / HRV, kutentha kwa mpweya, kugwiritsira ntchito mpweya wa AHU, dongosolo loyeretsa mpweya.Kupatula apo, Holtop akatswiri projekiti yankho gulu lingaperekenso makonda hvac mayankho makampani osiyanasiyana.
Pansipa pali zinthu zina zokhudzana ndi izi, chonde titumizireni ngati mukufuna chilichonse mwazinthu zathu za HRV/ERV/Heat exchanger.
