Kwinjizamo: Gushyira hamwe bingana imikorere mibi yimyuka yimiyoboro yoroheje. Kwiyubaka gukomeye bingana imikorere ikomeye yumwuka uva mumiyoboro yoroheje. Uhitamo uko ibicuruzwa byawe bizakora. (dukesha David Richardson)
Benshi mu nganda zacu bemeza ko ibikoresho byumuyoboro bikoreshwa mugushiraho bigena ubushobozi bwa sisitemu ya HVAC yo kwimura umwuka. Kubera iyi mitekerereze, imiyoboro yoroheje akenshi ibona rap mbi. Ikibazo ntabwo ari ubwoko bwibikoresho. Ahubwo, dushyira ibicuruzwa.
Mugihe ugerageje sisitemu idakora neza ikoresha imiyoboro yoroheje, uzahura nibibazo byogusubiramo bigabanya umuvuduko wumwuka kandi bigabanya ihumure nuburyo bwiza. Ariko, nukwitondera amakuru arambuye, urashobora gukosora byoroshye no gukumira amakosa akunze kugaragara. Reka turebe inama eshanu zagufasha kurushaho gushiraho imiyoboro yoroheje kugirango sisitemu yawe ikore neza.
Kugirango uzamure ubwiza bwubwubatsi, irinde impinduka zikomeye zumuyoboro uhetamye kubiciro byose. Sisitemu ikora neza mugihe ushyizeho imiyoboro igororotse bishoboka. Hamwe n'inzitizi nyinshi mumazu agezweho, ntabwo buri gihe ari amahitamo.
Iyo umuyoboro ugomba guhinduka, gerageza kubika byibuze. Murebure, ubugari burakora neza kandi bwemerera umwuka kunyura byoroshye. Sharp 90 ° yunama umuyoboro woroshye imbere kandi igabanya umwuka utangwa. Nkuko impinduka zikomeye zigabanya umwuka, umuvuduko uhagaze muri sisitemu uriyongera.
Ahantu hamwe usanga aho izo mbogamizi zibera ni mugihe amazi yohasi adahujwe no guhaguruka no kwambara. Ihuriro akenshi rifite impinduka zikomeye zibangamira umwuka. Mukosore ibi mutanga umuyoboro uhagije kugirango uhindure icyerekezo cyangwa ukoresheje inkokora yicyuma.
Gutegura ibyubaka nikindi kibazo gisanzwe uzasanga muri attike nyinshi. Kugira ngo ukemure ibi, ushobora gukenera guhindura umuyoboro cyangwa gushaka ahandi hantu kugirango wirinde guhinduka gukabije.
Indi mpamvu ikunze gutera guhumeka nabi no guhumuriza ibibazo ni kugabanuka kubera inkunga idahagije. Abashiraho benshi bamanika imiyoboro kuri metero 5-6 gusa, zishobora gutera kugabanuka cyane mumiyoboro. Iyi miterere ikomera kubuzima bwumuyoboro kandi ikomeza kugabanya umwuka. Byiza, umuyoboro woroshye ntugomba kugabanuka kurenza santimetero 1 z'uburebure bwa metero 4.
Imiyoboro yunamye hamwe no kugabanuka bisaba inkunga yinyongera. Iyo ukoresheje ibintu bimanitse bimanikwa nka kaseti ifata cyangwa insinga, umuyoboro urashobora gufungirwa aha. Mu bihe bikomeye, insinga zirashobora guca mu miyoboro, bigatuma umwuka winjira mu bice bitagenewe inyubako.
Iyo ubwo busembwa buhari, umwuka urahagarikwa kandi ugatinda. Kugira ngo ukemure ibyo bibazo, shyiramo inkunga mugihe kinini, nka buri metero 3 aho kuba metero 5, 6, cyangwa 7.
Mugihe ushyizeho izindi nkunga, hitamo ibikoresho byawe byo guhambira kugirango wirinde kwifata utabishaka. Koresha byibura clamp-3 cyangwa clamps kugirango ushyigikire umuyoboro. Imiyoboro y'imiyoboro nigicuruzwa cyiza gishobora no gukoreshwa mugushigikira neza imiyoboro yoroheje.
Ubundi busembwa busanzwe butera umwuka mubi bibaho mugihe ingirabuzimafatizo yimiyoboro ihindagurika iyo ifatanye na boot cyangwa iyo ikuweho. Ibi birashobora kubaho niba utarambuye intoki ukayigabanya kuburebure. Niba udakoze ibi, ikibazo cyo gukomera kizarushaho kwiyongera mugukanda intoki mugihe ukurura insulation hejuru ya boot cyangwa cola.
Mugihe cyo gusana imiyoboro, mubisanzwe dukuramo metero zigera kuri 3 zingirakamaro zishobora kubura kugenzura neza. Nkigisubizo, twapimye ubwiyongere bwikirere bwa 30 kugeza 40 cfm ugereranije numuyoboro wa 6 ..
Witondere rero gukurura umuyoboro uko bishoboka kose. Nyuma yo guhuza umuyoboro kuri boot cyangwa kuyikuraho, ongera uyizirike kurundi ruhande kugirango ukureho intandaro irenze. Kurangiza guhuza uhuza kurundi ruhande no kurangiza kwishyiriraho.
Ibyumba bya plenum byitaruye ni agasanduku k'urukiramende cyangwa inyabutatu ikozwe mu miyoboro iva mu majyepfo. Bahujije umuyoboro munini woroshye mu cyumba, ugaburira imiyoboro mito mito isohoka mu cyumba. Igitekerezo gisa nkicyizere, ariko bafite ibibazo ugomba kumenya.
Ibi bikoresho bifite umuvuduko mwinshi ugabanuka no kubura icyerekezo cyoguhumeka nkuko ikirere kigerageza kuva mubikwiye. Umwuka wabuze muri plenum. Ibi ahanini biterwa no gutakaza imbaraga muburyo bukwiye mugihe umwuka watanzwe kuva kumuyoboro ujya kwaguka wagutse mumwanya munini. Umuvuduko uwo ariwo wose wo mu kirere uzamanuka aho.
Inama nakugira rero ni ukwirinda ibi bikoresho. Ahubwo, tekereza uburyo bwagutse bwo kuzamura sisitemu, gusimbuka birebire, cyangwa inyenyeri. Igiciro cyo gushiraho ibyo bingana kizaba kiri hejuru gato yo gushyiraho plenum ya kure, ariko iterambere ryimikorere yikirere rizahita rigaragara.
Niba ufite ingano ukurikije amategeko ashaje yerekana igikumwe, urashobora gukora ikintu kimwe nka mbere kandi sisitemu yawe iracyakora nabi. Iyo ukoresheje uburyo bumwe bukora kumpapuro zicyuma kugirango ubone ubunini bworoshye, bivamo umwuka muke hamwe numuvuduko mwinshi uhagaze.
Ibikoresho byo kuvoma bifite imiterere ibiri yimbere. Urupapuro rwurupapuro rufite ubuso bunoze, mugihe ibyuma byoroshye bifite intangiriro zingana. Itandukaniro akenshi ritanga igipimo cyimyuka itandukanye hagati yibicuruzwa byombi.
Umuntu umwe nzi ushobora gukora imiyoboro yoroheje nkicyuma ni Neil Comparetto wo muri Comfort Squad muri Virginia. Akoresha uburyo bushya bwo kwishyiriraho butuma uruganda rwe rugera kumikorere imwe yibikoresho byombi.
Niba udashobora kubyara imashini ya Neal, sisitemu yawe izakora neza niba wateguye umuyoboro munini wa flex. Abantu benshi bakunda gukoresha ibintu byo guteranya 0.10 mubibara byabo hanyuma bakibwira ko santimetero 6 z'umuyoboro zizatanga umuvuduko wa cfm 100. Niba aribyo witeze, ibisubizo bizagutenguha.
Ariko, niba ugomba gukoresha Metal Pipe Calculator hamwe nagaciro gasanzwe, hitamo ubunini bwumuyoboro ufite coefficient de friction ya 0.05 hanyuma ukurikize amabwiriza yo kwishyiriraho hejuru. Ibi biguha amahirwe meza yo gutsinda hamwe na sisitemu yegereye ingingo.
Urashobora kujya impaka umunsi wose kubijyanye nuburyo bwo gushushanya imiyoboro, ariko kugeza igihe ufashe ibipimo hanyuma ukareba neza ko kwishyiriraho bitanga umwuka ukeneye, byose ni ugukeka. Niba urimo kwibaza uburyo Neil yari azi ko ashobora kubona ibintu byuma byo gutekesha, ni ukubera ko yabipimye.
Agaciro kapimye ikirere kiva mububiko buringaniye niho reberi ihurira n'umuhanda kugirango ushyireho imiyoboro ihindagurika. Ukoresheje inama zavuzwe haruguru, urashobora kwereka ushyiraho ubwiyongere bwimyuka yo mu kirere ibyo kunoza bizana. Mufashe kubona uburyo ibitekerezo byabo kubintu birambuye.
Sangira izi nama nuwashizeho hanyuma ushake ubutwari bwo kwinjiza neza sisitemu yo gukoresha amazi. Guha abakozi bawe amahirwe yo gukora akazi neza ubwambere. Abakiriya bawe bazabishima kandi ntuzabura guhamagara.
