I-AIRHEAD: Ungatsho ngokuzithemba ukuba indlela yokuyila i-duct iyasebenza ukuba umlinganiselo wokuhamba komoya uyi-± 10% yohambo olubaliweyo lomoya.
Imibhobho yomoya yenye yezona zinto zibaluleke kakhulu kwi-ventilation kunye ne-air conditioning system.IiNkqubo eziPhezulu zeHVAC zibonisa ukuba izinto ezili-10 zisebenza kunye ukumisela ukusebenza kombhobho.Ukuba enye yezi zinto ayihoywanga, yonke inkqubo ye-HVAC inokungaboneleli ngentuthuzelo kunye nokusebenza kakuhle okulindele kubathengi bakho.Makhe sijonge ukuba ezi zinto zigqiba njani ukusebenza kwesixokelelwano sakho semibhobho kunye nendlela yokuqinisekisa ukuba ichanekile.
Iifeni zangaphakathi (izivuthela) kulapho iimpawu zemibhobho yomoya ziqala khona.Imisela ubungakanani bomoya onokuthi ekugqibeleni ujikeleze ngombhobho.Ukuba ubungakanani bombhobho buncinci kakhulu okanye bufakwe ngokungachanekanga, umqhubi akayi kukwazi ukubonelela ukuhamba komoya okufunekayo kwinkqubo.
Ukuqinisekisa ukuba abalandeli bomelele ngokwaneleyo ukuhambisa inkqubo yomoya efunekayo, kufuneka ubhekisele kwitshathi yefeni yesixhobo.Olu lwazi luhlala lufumaneka kwimiyalelo yokufakela umenzi okanye idatha yobugcisa.Jonga kuyo ukuze uqiniseke ukuba ifeni inokukoyisa ukuxhathisa kokuhamba komoya okanye ukuhla koxinzelelo kwiikhoyili, izihluzi kunye nemibhobho.Uya kumangaliswa koko unokukufunda kulwazi lwesixhobo.
Ikhoyili yangaphakathi kunye nesihluzo somoya zizinto ezimbini eziphambili zenkqubo apho ifeni kufuneka idlule umoya.Ukuchasana kwabo ekuhambeni komoya kuchaphazela ngokuthe ngqo ukusebenza kombhobho.Ukuba zithintele kakhulu, zinokuwunciphisa kakhulu ukuhamba komoya phambi kokuba ushiye iyunithi yokuphefumla.
Unganciphisa amathuba okucheba iikhoyili kunye nezihluzi ngokwenza umsebenzi omncinci kwangaphambili.Jonga kulwazi lomenzi wekhoyili kwaye ukhethe ikhoyili yangaphakathi eya kubonelela ngomoya ofunekayo wokuhamba koxinzelelo olusezantsi xa imanzi.Khetha isihluzo somoya esihlangabezana neemfuno zempilo kunye nococeko lwabathengi ngelixa ugcina uxinzelelo olusezantsi kunye nesantya sokuhamba.
Ukukunceda ubungakanani obuchanekileyo bokucoca isihluzo sakho, ndingathanda ukucebisa iZiko leSizwe leComfort Institute (NCI) “INkqubo yoHluzo loHlulo”.Ukuba ungathanda ikopi yePDF nceda undithumelele isicelo se-imeyile.
Uyilo oluchanekileyo lwemibhobho sisiseko sofakelo lwemibhobho.Yile ndlela i-duct efakiweyo iya kujongeka ngayo ukuba zonke iziqwenga ziyadibana njengoko kulindelekile.Ukuba uyilo lungalunganga kwasekuqaleni, ukusebenza kombhobho (kunye nenkqubo yonke ye-HVAC) inokubandezeleka ngenxa yokuhanjiswa komoya okungafanelekanga.
Iingcali ezininzi kushishino lwethu zicinga ukuba uyilo olululo lwemibhobho lulingana ngokuzenzekelayo nokusebenza kwenkqubo ye-duct, kodwa akunjalo.Ukuqinisekisa ukuba indlela yokuyila umbhobho wakho iyasebenza, nokuba yintoni na, kufuneka ulinganise ukuhamba komoya okwenyani kwenkqubo yakho yokwakha.Ukuba i-airflow elinganisiweyo yi-± 10% ye-airflow ebalwayo, ungachaza ngokuzithemba ukuba indlela yakho yokubala ye-duct iyasebenza.
Olunye uqwalaselo luphathelene noyilo lwezixhobo zombhobho.Isiphithiphithi esigqithileyo ngenxa yofakelo lwemibhobho eyilwe kakubi kunciphisa ukuhamba komoya okusebenzayo kwaye kwandisa ukuxhathisa ekufuneka ukoyise ifeni.
Izifakelo zemibhobho yomoya kufuneka zinike ukususwa ngokuthe ngcembe nangokugudileyo kokuhamba komoya.Gwema ukujika okubukhali kunye nokunciphisa ukufakwa kwemibhobho ukuphucula ukusebenza kwabo.Ushwankathelo olufutshane lwe-ACCA Handbook D luya kukunceda wenze isigqibo sokuba loluphi ulungelelwaniso olufanelekileyo oluya kusebenza kakuhle.Izixhobo ezinobude obufutshane obulinganayo zibonelela ngobonelelo lomoya olusebenzayo.
Isixokelelwano sombhobho oxineneyo siya kugcina umoya ujikeleza ngefeni ngaphakathi kwemibhobho.Umbhobho ovuzayo unokunciphisa ukusebenza kwenkqubo kwaye ubangele iingxaki ezahlukeneyo, kubandakanywa ne-IAQ kunye ne-CO imiba yokhuseleko, kunye nokunciphisa ukusebenza kwenkqubo.
Ukwenza lula, naluphi na uqhagamshelo lomatshini kwisixokelelwano sombhobho kufuneka lutywinwe.I-Putty isebenza kakuhle xa kungekho mfuneko yokuphazamisa uqhagamshelo, njengombhobho okanye uqhagamshelo lwemibhobho yamanzi.Ukuba kukho icandelo emva kokudibanisa komatshini kunokufuna ukulungiswa kwixesha elizayo, njengekhoyili yangaphakathi, sebenzisa i-sealant ekhutshwayo ngokulula.Musa ukuncamathelisa umsebenzi kwiipaneli zezixhobo zokungenisa umoya.
Xa umoya ungaphakathi kumbhobho, kufuneka ube nendlela yokuwulawula.I-Volumetric dampers ikuvumela ukuba ulawule indlela yokuhamba komoya kwaye ibaluleke kakhulu ekusebenzeni kakuhle kwenkqubo.Iinkqubo ezingenazo i-dampers ezininzi zivumela umoya ukuba ulandele indlela yokuchasana okuncinci.
Ngelishwa, abaqulunqi abaninzi bajonga ezi zixhobo zingeyomfuneko kwaye azibandakanyi kwiifakelo ezininzi zemibhobho.Indlela echanekileyo yokwenza oku kukuzifakela kunikezelo kunye nokubuyisela amasebe e-duct ukuze ukwazi ukulinganisa ukuhamba komoya ngaphakathi nangaphandle kwegumbi okanye indawo.
Ukuza kuthi ga ngoku, sigxile kuphela kwinkalo yomoya.Iqondo lobushushu yenye into yokusebenza kwenkqubo yombhobho ekufuneka ingahoywa.Imibhobho yomoya ngaphandle kwe-insulation ayikwazi ukunika umlinganiselo ofunekayo wokushisa okanye ukupholisa kumagumbi ane-air-conditioning.
Ukugqunywa kombhobho kugcina ubushushu bomoya ngaphakathi kumbhobho ngendlela yokuba iqondo lobushushu kwindawo yokuphuma yeyunithi lisondele kulowo umthengi uya kuziva ekuphumeni.
I-Insulation efakwe ngokungalunganga okanye ngexabiso eliphantsi le-R ayiyi kuthintela ukulahleka kobushushu kumbhobho.Ukuba umahluko weqondo lobushushu phakathi kweqondo lobushushu leyunithi kunye nelona qondo liphezulu lonikezelo lomoya lingaphezulu kwe-3 ° F, ukugqunywa kwemibhobho eyongezelelweyo kunokufuneka.
Iirejista zesondlo kunye ne-grill yokubuyisela yinxalenye ehlala ingahoywa yokusebenza kwenkqubo ye-plumbing.Ngokuqhelekileyo abaqulunqi basebenzisa ezona rejista ziphantsi kunye neegrile.Abantu abaninzi bacinga ukuba eyona njongo yabo kukuvala izivulo ezirhabaxa kunikezelo kunye nemigca yokubuya, kodwa benza okungakumbi.
Irejista yokubonelela ilawula ukunikezelwa kunye nokuxuba umoya ococekileyo kwigumbi.I-grilles yokubuyisela umoya ayichaphazeli ukuhamba komoya, kodwa ibalulekile ngokubhekiselele kwingxolo.Qinisekisa ukuba abantyiloza okanye abaculi xa abalandeli bebaleka.Jonga kulwazi lomenzi wegrayiti kwaye ukhethe irejista efanele ukuhamba komoya kunye negumbi onqwenela ukulilawula.
Olona tshintsho lukhulu ekumiseleni ukusebenza kwenkqubo yemibhobho yindlela yokufakela imibhobho.Kwanenkqubo efanelekileyo inokusilela ukuba ifakwe ngokuchanekileyo.
Ingqwalasela kwiinkcukacha kunye nocwangciso oluncinci luhamba indlela ende ekufumaneni ubuchule obufanelekileyo bofakelo.Abantu baya kumangaliswa xa bebona ukuba kungakanani ukuhamba komoya okunokufumaneka kwi-flexible ducting ngokususa i-core excess and kinks kunye nokongeza i-hanger.Impendulo ye-reflex kukuba imveliso inetyala, kungekhona i-installer esetyenziswayo.Oku kusizisa kumbandela weshumi.
Ukuqinisekisa uyilo oluyimpumelelo kunye nokufakwa kwenkqubo yombhobho, kufuneka iqinisekiswe.Oku kwenziwa ngokuthelekisa idatha yoyilo kunye nedatha elinganiswe emva kokuba inkqubo ifakiwe.Imilinganiselo yokuphuma komoya yegumbi ngalinye kumagumbi anemeko kunye notshintsho lobushushu kwimibhobho yimilinganiselo emibini ephambili ekufuneka iqokelelwe.Zisebenzise ukujonga ubungakanani be-BTU eziziswe kwisakhiwo kunye nokuqinisekisa ukuba iimeko zoyilo ziyafezekiswa.
Oku kunokubuyela kuwe ukuba uthembele kwindlela yakho yoyilo, ucinga ukuba inkqubo iziphatha ngendlela elindelekileyo.Ukulahleka kobushushu / inzuzo, ukukhethwa kwezixhobo kunye nokubalwa koyilo lwemibhobho akukaze kujongwe ukuqinisekisa ukusebenza - hayi ngaphandle komxholo.Endaweni yoko, zisebenzise njengeethagethi zemilinganiselo yentsimi yeenkqubo ezifakelweyo.
Ngaphandle kokugcinwa, ukusebenza kwesixokelelwano sakho semibhobho kuya kuthotywa ngokuhamba kwexesha.Cinga ngendlela umonakalo owenziwe ngayo kwimibhobho yomoya esuka kwiisofa okanye iingcingo zabafana ezingqiyame ngeendonga ezisecaleni eziphazamisana nokuhamba komoya—uyibona njani?
Qala ukulinganisa kunye nokurekhoda uxinzelelo lwakho olungagungqiyo kuyo yonke ifowuni.Emva kokuqinisekisa ukuba inkqubo ye-plumbing isebenza ngokufanelekileyo, eli nyathelo lokuphindaphinda likuvumela ukuba ubeke iliso kulo naluphi na utshintsho.Oku kukuvumela ukuba uhlale uqhagamshelwe kwi-ductwork kwaye ikunika ukuqonda okungcono kwemiba ethoba isidima senkqubo yakho yokutsala.
Lo mbono wezinga eliphezulu malunga nendlela ezi 10 ezisebenza ngayo kunye ukumisela ukusebenza kwenkqubo ye-duct yenzelwe ukuba ucinge.
Zibuze ngokunyanisekileyo: yeyiphi kwezi zinto oziqwalaselayo, kwaye yeyiphi omele uyinikele ingqalelo?
