Njengoba izindinganiso ezintsha zamakhodi wokwakha ziholela ezimvilophini zokwakha eziqinile, amakhaya adinga izixazululo zemishini zokungenisa umoya ukuze kugcinwe umoya wasendlini uhlanzekile.
Impendulo elula esihlokweni salesi sihloko yinoma ubani (umuntu noma isilwane) ohlala futhi osebenza endlini.Umbuzo omkhulu ukuthi sizokwenza kanjani ukunikeza umoya omusha owanele onomoya-mpilo wokwakha izakhamuzi kuyilapho sigcina amazinga ancishisiwe okusetshenziswa kwamandla e-HVAC njengoba kuyalelwe yimithetho kahulumeni yamanje.
Igqugquzelwa ukuwa kwesivumelwano sikawoyela ekuqaleni kwawo-1970, uMnyango Wezamandla wase-US (DOE) waqala uhlelo oluhlanganisa konke lokuvikela amandla olwaholela ekutheni abalawuli baseNyakatho Melika bathuthukise amazinga akhula njalo e-HVAC noma Amazinga Okusebenza Kahle Okuncane. (MEPS).
Kanye nezinto zikagesi ze-HVAC ezonga amandla kakhudlwana enye inkambiso iholele ekuvaleni izindlu ziqine ngangokunokwenzeka ngamafasitela abambayo, izicabha, imigoqo yomusi kanye namathini okunwetshwa kwegwebu.
Ocwaningweni oluthile lokulungiswa kwezindawo zokuhlala zenkathi yama-90, indlu okukhulunywa ngayo yayicindezelekile ngaphezu kwama-pascal angu-50 lapho zonke izinto zikagesi eziqeda umoya (amafeni egumbi lokugezela, ihood yekhishi) sezisebenza.Lokho kuwukucindezelwa okuphindwe ka-10 kunalokho okuvunyelwe, ikakhulukazi ngezinto zikagesi eziphehlwa ngamathambo ensimbi ngaphakathi kwesakhiwo.Sidinga umoya!
Hlobo Luni Lomoya?
Ngezimvilophu zokwakha zanamuhla eziqinile kudingeka sicabangele indlela yokwethula umoya ngaphakathi nokuthi kungani.Futhi singase sidinge izinhlobo eziningana zomoya.Ngokuvamile kuba nohlobo olulodwa lomoya, kodwa ngaphakathi kwesakhiwo sidinga umoya ukuze senze izinto ezihlukene kuye ngemisebenzi yethu yasendlini.
Umoya wokungenisa umoya uwuhlobo olubaluleke kakhulu kubantu nasezilwaneni.Abantu baphefumula cishe ama-30 lbs.womoya nsuku zonke kuyilapho sichitha cishe u-90% wezimpilo zethu sisendlini.Ngesikhathi esifanayo, kuyadingeka ukususa umswakama owedlulele, iphunga, i-carbon dioxide, i-ozone, izinhlayiya nezinye izinhlanganisela eziyingozi.Futhi ngenkathi uvula iwindi kunikeza umoya wokungenisa umoya odingekayo, lokhu kungena komoya okungalawulwa kuzobangela amasistimu e-HVAC ukuthi adle amandla amaningi—amandla okufanele siwawonge.
Umoya wokwenza izimonyo umoya ongena uvela ngaphandle okuhloswe ngawo ukufaka esikhundleni salowo moya ophelelwa amandla amathuluzi afana namahodi ahlukahlukene namafeni asendlini yangasese, amasistimu evacuum aphakathi nendawo nezomisa izingubo.Izindlu zanamuhla ezakhiwe ngamakhodi akamuva cishe awasawudingi umoya wokuzilungisa ngaphandle uma izivalo ezinkulu ezihambisa umoya omkhulu (ngaphezu kuka-200 cfm) zifakwe abapheki abashiseka ngokweqile.
Okokugcina, kukhona futhi umoya ovuthayo, umoya owawuhloselwe ukusetshenziswa nezinto ezibaswa yizinsalela ezifana neziko legesi, izifudumezi zamanzi, izitofu kanye nezindawo zokubasa izinkuni.Ngokuvala zonke izikhala zokuvuza komoya ezingase zicatshangwe ezindlini zanamuhla, izinto zikagesi kufanele “ziboleke” umoya wokungenisa umoya ngaleyo ndlela zidale inkinga eyingozi.Izinto zikagesi ezingakwazi ukuphuma ngenxa yokucindezeleka, noma ukulambela umoya, zingase ziqale ukushisa imikhiqizo yazo ye-flue zidale i-carbon monoxide ebulalayo, inhlekelele eqede ukuphila kwabantu abaningi kakhulu phakathi neminyaka edlule.
SethulaHRVfuthiERV
Izakhiwo ezindala zazivuza kangangokuthi umoya ongena ngaphakathi wawuhlangabezana nazo zonke izidingo zokungenisa umoya kalula, kodwa hhayi ngaphandle kwezinhlawulo.Umoya ongenayo wawudinga ukufakwa umoya ngokushisa futhi mhlawumbe nomswakama oletha izindleko ezengeziwe zophethiloli nokunakekela.Izindlu zazinodaka, abahlali babevame ukuzizwa bengakhululekile njengoba umoya owomile uhwamuka umswakama omningi esikhumbeni udala umuzwa wokubanda kakhulu.Ukunqwabelana kukagesi omile kumakhaphethi nefenisha kwabangela ukwethuka okubuhlungu lapho umninikhaya oshajwe ngogesi ethinta indawo ephansi.Ngakho-ke, yikuphi okungcono?
I-ventilator yokuvuselela ukushisa (HRV) iyisisombululo somshini wokungenisa umoya esizosebenzisa umsinga wokukhipha umoya okudala ushisa ngaphambili umthamo ofanayo wokubanda ongena emoyeni ohlanzekile wangaphandle.
Njengoba ama-airstreams edlulana phakathi kwe-HRV, ukushisa komoya okungaphezulu kwama-75% noma okungcono kuzodluliselwa emoyeni obandayo ngaleyo ndlela kunikeze umoya odingekayo kuyilapho kunciphisa izindleko “zokwenza” ukushisa okudingekayo ukuletha lokho. umoya omusha ofinyelela kuzinga lokushisa legumbi elizungezile.
Ezindaweni ezinomswakama, ezinyangeni zasehlobo i-HRV izokwandisa izinga lokuswakama endlini.Njengoba iyunithi yokupholisa isebenza futhi namafasitela evaliwe, indlu isadinga umoya owanele.Isistimu yokupholisa enosayizi ofanele eklanywe kucatshangwa ngomthwalo ocashile wasehlobo kufanele ikwazi ukubhekana nomswakama owengeziwe, okuvunyiwe, ngezindleko ezengeziwe.
I-ventilator yokubuyisela amandla (ERV), isebenza ngendlela efanayo neye-HRV, kodwa phakathi nobusika omunye umswakama osemoyeni ubuyiselwa endaweni yasendlini.Okufanelekile, ezindlini eziqinile, i-ERV izosiza ukugcina umswakama wasendlini ebangeni elingu-40% eliphikisana nemiphumela engemihle nengenampilo yomoya owomile wasebusika.
Ukusebenza kwasehlobo kwenza i-ERV yenqabe cishe u-70% womswakamo ongenayo obubuyisela ngaphandle ngaphambi kokuthi ilayishe isistimu yokupholisa.I-ERV ayisebenzi njengesisusa umswakama.
Ama-ERV Angcono Kusimo Sezulu Esinomswakama
Ochwepheshe bokungena komoya bazothi indawo ekahle yokufaka umoya eyimishini yanoma iliphi ikhaya incike esimweni sezulu sendawo, indlela yokuphila yabahlali kanye nezidingo ezithile zomnikazi.Isibonelo, ezindlini lapho izinga lomswakamo lasebusika livame ukukhuphuka libe ngaphezu kuka-55%, i-HRV ingenza umsebenzi ongcono wokususa ukuswakama okweqile.
Ochwepheshe futhi bayavuma ukuthi izindlu ezintsha, noma lezo ezivuselelwe zaba ikhodi yokwakha yakamuva, kufanele zibe ne-ERV ecacisiwe njengoba izakhiwo ezifakwe amafasitela acwebezelisiwe kathathu kanye nezindlu zangaphansi ezivalwe kahle zingasekela umswakama ophakeme ohlobene ezinyangeni zasebusika: 35% +/- 5% kuyamukeleka.

Ukucatshangelwa kokufakwa
Nakuba amayunithi e-ERV/HRV adizayinelwe ukufakwa endaweni yokuhlala engafakwa ngendlela eyenziwe lula kusetshenziswa isistimu ekhona yokubamba umoya ukuze kusatshalaliswe umoya opholile, ungakwenzi ngaleyo ndlela uma kungenzeka.
Ngokubona kwami, kungcono kakhulu ukufaka isistimu yepayipi elizinikele ngokugcwele ekwakheni okusha noma emisebenzini yokuvuselela ephelele.Isakhiwo sizozuza ekusabalaliseni komoya onesimo esingcono kakhulu kanye nezindleko zokusebenza eziphansi kakhulu, njengoba isithando somlilo noma isibambi somoya ngeke sidingeke.
Eminye yemishini engcono kakhulu ye-HRV/ERV emakethe ifaka amamotho e-EC futhi ilawula ama-algorithms akwazi ukulinganisa ngokuzenzakalelayo amasistimu futhi avumelane nezinguquko zengcindezi.
Kungase kuthathe isikhathi ukukholisa bonke abanikazi bezindlu ukuthi ukungena komoya ngomshini kudlula ngempela ukuvula amafasitela nganoma yisiphi isikhathi.Abantu basemadolobheni ngempela banentshisekelo ebekiwe yokuthembela ekufakweni komoya okusebenzayo kanye nabanakekelwa kahle, okuthile, njengoba ucwaningo lubonisa, abakaze babe nakho ngaphambili.
Isibonelo sokufakwa kwe-HRV nge-ductwork eqondile.(umthombo:I-NRCan Publication (2012):Ama-Ventilator Okubuyisela Ukushisa)
I-Holtop ingumkhiqizi ohamba phambili e-China onguchwepheshe ekukhiqizeni imishini yokubuyisela ukushisa emoyeni kuya emoyeni.Inikezelwe ocwaningweni nasekuthuthukisweni kobuchwepheshe emkhakheni wokungenisa umoya wokuvuselela ukushisa kanye nemishini yokuphatha umoya yokonga amandla kusukela ngo-2002. Imikhiqizo eyinhloko ihlanganisa i-ventilator yokubuyisela amandla i-ERV/HRV, isishintshi sokushisa komoya, iyunithi yokusingatha umoya i-AHU, uhlelo lokuhlanza umoya.Ngaphandle kwalokho, ithimba lesixazululo sephrojekthi ye-Holtop linganikeza nezixazululo ezenziwe ngezifiso ze-hvac embonini eyahlukene.
Ngezansi kukhona imikhiqizo ehlobene, sicela usithinte uma unentshisekelo kunoma yimiphi imikhiqizo yethu ye-HRV/ERV/Heat exchanger.
