Iindlela ezahlukeneyo. Kukho iintlobo ezininzi zeenkqubo zokubhobhoza kwizicelo ezingenasiphelo. Oku kufana nokutywinwa kombhobho kunye nendlela echaphazela ngayo ukusebenza kakuhle kwenkqubo kunye nokugcinwa kwamandla.
Emva kovavanyo lwelabhoratri, ukusebenza kakuhle kwenkqubo ye-HVAC kufikelele kubukhulu bayo phantsi kweemeko eziphantse zibe zilungile. Ukuvelisa kwakhona ezi ziphumo kwihlabathi lenene kufuna ulwazi kunye nomgudu wokufaka nokugcina inkqubo. Inxalenye ebalulekileyo yokusebenza kakuhle yi-ductwork. Kukho iintlobo ezininzi zeenkqubo zemibhobho yosetyenziso olungenasiphelo. Esi sidla ngokuba sisihloko apho iikontraka ze-HVAC zinokuxoxa ngaso. Nangona kunjalo, ngeli xesha incoko iguqukela ekutywinweni kombhobho kunye nendlela echaphazela ngayo ukusebenza kakuhle kwenkqubo kunye nokonga amandla.
Kwiphulo layo lokutywinwa kwemibhobho, i-ENERGY STAR® ilumkisa abaninimzi abasebenzisa ukufudumeza komoya okunyanzeliswayo kunye neenkqubo zokupholisa ukuba malunga ne-20 ukuya kwi-30 yeepesenti zomoya ohamba nge-duct system inokulahleka ngenxa yokuvuza, imingxuma kunye nokudibanisa kakubi kwemigudu.
"Isiphumo siphezulu samatyala asetyenziswayo kunye nexesha elinzima ukugcina ikhaya lakho likhululekile, kungakhathaliseki ukuba i-thermostat ibekwe njani," itsho iwebhusayithi ye-Energy Star. “Ukutywina kunye ne-insulating ducts kunokunceda ukucombulula iingxaki eziqhelekileyo kunye nokuphucula umgangatho womoya wangaphakathi. kwaye unciphise ukubuya umva.” igesi kwindawo yokuhlala.”
Umbutho ulumkisa ukuba iinkqubo zemibhobho zinokuba nzima ukufikelela kuzo, kodwa zibonelela abaninimzi ngoluhlu lokukhangela olwenzayo olubandakanya ukuhlolwa, ukutywina izivulo ngeteyiphu okanye iteyiphu yefoyile, kunye nemibhobho yokusongela ehamba kwiindawo ezingenakunqandwa kunye ne-insulation air ducts Emva kokugqiba. onke la manyathelo, i-Energy Star icebisa ukuba abaninimzi banenkqubo ehlolwe yingcali. Ikwavumela abaninimzi bazi ukuba uninzi lweekontraki ezichwephesha ze-HVAC ziya kulungisa kwaye zifakele i-ductwork.
Ngokutsho kwe-Energy Star, iingxaki ezine ezixhaphakileyo zemibhobho ziyavuza, ziqhawuke kwaye ziqhawuke ziqhawuke; amatywina angalunganga kwiirejista kunye neegrile; ukuvuza kwii-oveni kunye neetreyi zokucoca; kunye neekinks kwiinkqubo zemibhobho eguquguqukayo ezithintela ukuhamba komoya. Izisombululo kwezi ngxaki ziquka ukulungiswa kwemibhobho kunye nokutywinwa; ukuqinisekisa ukulingana okuqinileyo kweerejista kunye ne-grilles kwiindlela zomoya; iziko lokutywina kunye nemikhombe yokucoca; kunye ne-insulating ductwork ngokufanelekileyo kwiindawo ezingagqitywanga.
Ukutywinwa kombhobho kunye nokugquma kusebenza kunye ukudala ubudlelwane be-symbiotic okwandisa ukusebenza kakuhle kunye nokuthuthuzela.
“Xa uthetha ngombhobho, ukuba awutywinwanga ngokufanelekileyo, ukugquma akuyi kuwenza umsebenzi wawo,” utshilo uBrennan Hall, umphathi omkhulu wemveliso ye-HVAC ye-Johns Manville Performance Materials. "Sihamba kunye neenkqubo zokutywina."
Uchaza ukuba emva kokuba inkqubo itywinwe, i-insulation ihambisa ukushisa okufunwa yinkqubo yokusingatha umoya ngokusebenzisa imibhobho, ukonga amandla kunye nokunciphisa ubushushu obuncinci okanye ukuzuza, kuxhomekeke kwindlela ekhethiweyo.
"Ukuba akukho kulahleka kobushushu okanye ukuzuza njengoko kudlula kwimibhobho, kuya kunceda ngokukhawuleza ukunyusa izinga lokushisa kwisakhiwo okanye kwikhaya kwindawo yokubeka i-thermostat efunwayo," kusho iHolo. "Inkqubo iya kuthi emva koko iyeke kwaye abalandeli bayeke ukusebenza, okuya kunceda ukunciphisa iindleko zamandla."
Isiphumo sesibini sokutywinwa ngokufanelekileyo kwemibhobho kukunciphisa ukujiya. Ukulawula i-condensation kunye nokufuma okugqithisileyo kunceda ukukhusela ukungunda kunye neengxaki zevumba.
“Isithintelo somphunga kwiimveliso zethu, nokuba yifilim okanye i-ductwork, yenza umahluko omkhulu,” utshilo uHolo. “Iipaneli zemibhobho kaJohn Manville zinciphisa ukulahleka kwamandla ngokucinezela ingxolo engafunwayo kunye nokugcina amaqondo obushushu angaguqukiyo. Bakwanceda ekudaleni indawo esempilweni yangaphakathi ngokunciphisa ukuvuza komoya kunye nokuthintela umonakalo obangelwa kukukhula kwentsholongwane. ”
Inkampani ayincedi kuphela iikontraka ngokuvelisa iintlobo ngeentlobo zeemveliso ukusombulula ingxolo ye-duct kunye neengxaki ezisebenzayo, kodwa idale nothotho loqeqesho lwasimahla kwi-intanethi kwi-HVAC yayo kunye nezisombululo zokufakelwa koomatshini.
"I-Johns Manville Academy inikezela ngeemodyuli zoqeqesho ezisebenzisanayo ezichaza yonke into ukusuka kwiziseko ze-insulation systems ukuya kwindlela yokuthengisa nokufaka iinkqubo ze-HVAC ze-Johns Manville kunye nemveliso yomatshini," kusho iHolo.
UBill Diederich, usekela mongameli we-Aeroseal wemisebenzi yokuhlala, uthe ukutywina imigudu yeyona ndlela yokwandisa ukusebenza kakuhle kwezixhobo zakho.
Ukutywina ukusuka ngaphakathi: Iikontraka zeAeroseal ziqhagamshela imibhobho ebekwe esicaba ukuya kumbhobho. Xa inkqubo yombhobho icinezelwa, ityhubhu ecaba isetyenziselwa ukuhambisa i-sealant efafaziweyo kwi-duct system.
"Enyanisweni, kwiiprojekthi ze-retrofit, ukutywinwa kwe-ductwork kunokunciphisa ubungakanani, okubangela ukuba kuncinci, ukufudumeza okuphantsi kunye neenkqubo zokupholisa," watsho. “Uphando lubonisa ukuba ukuya kuthi ga kwi-40% yomoya ongeniswa okanye ophuma kwigumbi uyalahleka ngenxa yokuvuza kombhobho. Ngenxa yoko, iinkqubo zeHVAC kufuneka zisebenze nzima kwaye ixesha elide kunesiqhelo ukufezekisa kunye nokugcina ubushushu begumbi obutofotofo. Ngokuhamba kwexesha Ngokuphelisa ukuvuza kwemibhobho, iinkqubo zeHVAC zinokusebenza kakuhle ngaphandle kokuchitha amandla okanye ukunciphisa ubomi besixhobo.
I-Aeroseal itywina i-ducts ikakhulu ngaphakathi kwenkqubo ye-duct kunokuba ivela ngaphandle. Imingxuma engaphantsi kwe-intshi ye-5/8 ububanzi iya kutywinwa kusetyenziswa inkqubo ye-Aeroseal, eyilelwe ukwenza lula inkqubo yokutywinwa kombhobho echazwe ngasentla.
Ukulungiswa kwemibhobho: Lungisa inkqubo yemibhobho yokudibanisa kwi-Aeroseal flat tubing. Xa inkqubo yombhobho icinezelwa, ityhubhu ecaba isetyenziselwa ukuhambisa i-sealant efafaziweyo kwi-duct system.
UDiederich uthi: “Ngokufaka isitshizi se-sealant kwimibhobho ephantsi koxinzelelo, i-Aeroseal ivala imibhobho evela ngaphakathi kungakhathaliseki ukuba ikuphi na, kuquka nemibhobho engafikelelekiyo emva kwe-drywall. "Isoftware yenkqubo ilandelela ukuncitshiswa kokuvuza ngexesha lokwenyani kwaye ikhupha isatifikethi sokugqitywa esibonisa ngaphambi nasemva kokuvuza."
Nakuphi na ukuvuza okukhulu kuno 5/8 intshi kunokutywinwa ngesandla. Ukuvuza okukhulu, okufana nemibhobho eyaphukileyo, eqhawukileyo okanye eyonakeleyo, kufuneka ilungiswe phambi kokutywinwa. Ngokutsho kwenkampani, iikontraka ziya kuchonga ezi ngxaki ngokuhlolwa okubonakalayo ngaphambi kokutywinwa. Ukuba kufunyenwe ingxaki enzulu ngexesha lokusetyenziswa kwe-Aeroseal Duct Sealing Spray, inkqubo iya kuyeka ngokukhawuleza ukumisa ukuhamba kwe-sealant, khangela ingxaki kwaye unikeze isisombululo kwi-site ngaphambi kokuba iqalise ukutywinwa.
“Ukongezelela ekusebenzeni okwandisiweyo, abathengi baya kufumanisa ukuba ukutywina imibhobho yabo kuphelisa ukungakhululeki namaqondo obushushu angalinganiyo kumakhaya abo; ikhusela uthuli ekungeneni kwimibhobho, iinkqubo zokuphatha umoya kunye nomoya abawuphefumlayo; yaye inokunciphisa iindleko zombane ukuya kutsho kuma-30 ekhulwini.” watsho. "Yeyona ndlela ilula nesebenzayo yokuba abaninimzi baphucule ukuhamba komoya kunye nokungena komoya ekhayeni labo, ukonyusa intuthuzelo kunye nomgangatho womoya ngelixa besindisa amandla kwaye behlisa amatyala asetyenziswayo."
