I-AIRHEAD: Ungasho ngokuzethemba ukuthi indlela yokuklama ipayipi iyasebenza uma ukugeleza komoya okukaliwe kungu-±10% wokugeleza komoya okubaliwe.
Amapayipi omoya angenye yezingxenye ezibaluleke kakhulu zesistimu yokukhipha umoya kanye ne-air conditioning. I-High Performance HVAC Systems ibonisa ukuthi izici ezingu-10 zisebenza ndawonye ukuze zinqume ukusebenza kwepayipi. Uma enye yalezi zici ishaywa indiva, lonke isistimu ye-HVAC ingase inganikezi ukunethezeka nokusebenza kahle oyilindele kumakhasimende akho. Ake sibheke ukuthi lezi zici zinquma kanjani ukusebenza kwesistimu yakho yamapayipi nokuthi ungaqiniseka kanjani ukuthi zilungile.
Amafeni angaphakathi (abashaya umoya) yilapho izici zamapayipi omoya ziqala khona. Inquma inani lomoya ongagcina ujikeleze emgudwini. Uma usayizi wepayipi umncane kakhulu noma ufakwe ngokungalungile, ifeni ngeke ikwazi ukunikeza ukugeleza komoya okudingekayo ohlelweni.
Ukuze wenze isiqiniseko sokuthi abalandeli baqine ngokwanele ukuhambisa ukugeleza komoya kwesistimu edingekayo, udinga ukubhekisela eshadini labalandeli bedivayisi. Lolu lwazi ngokuvamile lungatholakala emiyalweni yokufaka yomkhiqizi noma idatha yobuchwepheshe. Bheka kuyo ukuze uqiniseke ukuthi isiphephetha-moya singanqoba ukumelana nokugeleza komoya noma ukwehla kwengcindezi kumakhoyili, izihlungi namapayipi. Uzomangala ngalokho ongakufunda olwazini lwedivayisi.
Ikhoyili yangaphakathi nesihlungi somoya yizici ezimbili eziyinhloko zesistimu okufanele ifeni idlulise umoya ngazo. Ukumelana kwabo nokugeleza komoya kuthinta ngqo ukusebenza komgudu. Uma zivimbe kakhulu, zinganciphisa kakhulu ukugeleza komoya ngaphambi kokuba kuphume iyunithi yokufaka umoya.
Unganciphisa amathuba okugunda amakhoyili nezihlungi ngokwenza umsebenzi omncane kusengaphambili. Bheka ulwazi lomkhiqizi wekhoyili bese ukhetha ikhoyili yasendlini ezonikeza umoya odingekayo ngendlela ephansi yokwehla komfutho lapho imanzi. Khetha isihlungi somoya esihlangabezana nezidingo zezempilo nokuhlanzeka kwamakhasimende akho kuyilapho ugcina ukwehla kwengcindezi ephansi nezinga lokugeleza.
Ukukusiza usayizi olungile wokuhlunga kwakho, ngingathanda ukuphakamisa i-National Comfort Institute (NCI) “Uhlelo Lokulinganisa Usayizi”. Uma ungathanda ikhophi ye-PDF ngicela ungithumelele isicelo se-imeyili.
Ukwakhiwa kwamapayipi okulungile kuyisisekelo sokufakwa kwamapayipi. Yile ndlela ipayipi elifakiwe elizobukeka ngayo uma zonke izingcezu zihlangana njengoba kulindelekile. Uma idizayini iyiphutha kusukela ekuqaleni, ukusebenza kwe-ductwork (kanye nalo lonke uhlelo lwe-HVAC) kungahlupheka ngenxa yokulethwa kokugeleza komoya okungafanele.
Ochwepheshe abaningi embonini yethu bacabanga ukuthi ukwakheka kwepayipi elifanele lilingana ngokuzenzakalela nokusebenza kwesistimu yamapayipi, kodwa akunjalo. Ukuqinisekisa ukuthi indlela yakho yokuklama ipayipi iyasebenza, kungakhathaliseki ukuthi iyini, kufanele ulinganise ukugeleza komoya kwangempela kwesistimu yakho yokwakha. Uma ukugeleza komoya okukaliwe kungu-±10% wokugeleza komoya okubaliwe, ungasho ngokuzethemba ukuthi indlela yakho yokubala yepayipi iyasebenza.
Okunye okucatshangelwayo kumayelana nokuklanywa kokufakwa kwamapayipi. Isiyaluyalu esidlulele ngenxa yokufakwa kwamapayipi okuklanywe kabi kunciphisa ukugeleza komoya okusebenzayo futhi kukhuphule ukumelana nesiphepho okufanele sikunqobe.
Ukufakwa kwamapayipi omoya kufanele kunikeze ukususwa kancane kancane nokushelela kokugeleza komoya. Gwema ukujika okubukhali nokukhawulela ukufakwa kwamapayipi ukuze uthuthukise ukusebenza kwawo. Ukubuka kafushane kwe-ACCA Handbook D kuzokusiza ukuthi unqume ukuthi yikuphi ukucushwa okufanelekile okuzosebenza kangcono. Ukufakwa okunobude obufushane obulinganayo kunikeza umoya osebenza kahle kakhulu.
Isistimu yamapayipi aminyene izogcina umoya uzungeza ifeni ngaphakathi kwemigudu. Amapayipi avuzayo angehlisa izinga lokusebenza kwesistimu futhi abangele izinkinga ezihlukahlukene, okuhlanganisa izinkinga zokuphepha ze-IAQ ne-CO, kanye nokusebenza kwesistimu okuncishisiwe.
Ukwenza kube lula, noma yikuphi ukuxhumana kwemishini ohlelweni lwamapayipi kufanele kuvalwe. I-Putty isebenza kahle uma singekho isidingo sokuphazamisa uxhumano, njengepayipi noma uxhumano lwamapayipi. Uma kukhona ingxenye ngemuva kwelunga lemishini elingase lidinge ukulungiswa ngokuzayo, njengekhoyili yangaphakathi, sebenzisa isivalo esikhipheka kalula. Unganamathiseli umsebenzi kumaphaneli wemishini yokufaka umoya.
Uma umoya usemgudwini, udinga indlela yokuwulawula. Ama-dampers e-Volumetric akuvumela ukuthi ulawule indlela yokugeleza komoya futhi abalulekile ekusebenzeni okuhle kwesistimu. Amasistimu angenawo ama-dampers amaningi avumela umoya ukuthi ulandele indlela yokumelana okuncane.
Ngeshwa, abaklami abaningi babheka lezi zesekeli ngokungadingekile futhi azibandakanyi ekufakweni kwamapayipi amaningi. Indlela efanele yokwenza lokhu iwukuba uwafake emagatsheni okuhambisa nokuwabuyisela ukuze ukwazi ukulinganisa ukugeleza komoya ongena nokuphuma ekamelweni noma endaweni.
Kuze kube manje, sigxile kuphela esicini somoya. Izinga lokushisa lingesinye isici sokusebenza kwesistimu yamapayipi okungafanele sizitshwe. Amapayipi omoya angenawo ukufakwa kwe-insulation awakwazi ukunikeza inani elidingekayo lokushisa noma ukupholisa emakamelweni ane-air conditioning.
Ukufakwa kwamapayipi kugcina izinga lokushisa lomoya ngaphakathi kwepayipi ngendlela yokuthi izinga lokushisa endaweni yokuphuma kweyunithi lisondele kulelo umthengi azolizwa ekuphumeni.
I-insulation efakwe ngokungalungile noma enenani eliphansi le-R ngeke ivimbele ukulahlekelwa ukushisa epayipini. Uma umehluko wezinga lokushisa phakathi kwezinga lokushisa leyunithi kanye nezinga lokushisa lomoya elitholakala kude kakhulu lidlula u-3°F, kungase kudingeke ukwahlukanisa amapayipi okwengeziwe.
Amarejista okuphakelayo kanye nama-grill okubuyisela ayingxenye evame ukunganakwa yokusebenza kohlelo lwamapayipi. Ngokuvamile abaklami basebenzisa amarejista nama-grille ashibhe kakhulu. Abantu abaningi bacabanga ukuthi okuwukuphela kwenhloso yabo ukuvala izimbobo ezimahhadlahhadla olayini bokunikezwayo nababuyayo, kodwa benza okuningi kakhulu.
Irejista yokuhlinzeka ilawula ukuhlinzekwa kanye nokuxutshwa komoya opholile ekamelweni. Ama-grille omoya abuyayo awathinti ukugeleza komoya, kodwa abalulekile ngokomsindo. Qiniseka ukuthi abahuyizi noma abaculi uma abalandeli begijima. Bheka ulwazi lomkhiqizi we-grate bese ukhetha irejista evumelana kangcono nokugeleza komoya kanye negumbi ofisa ukulilawula.
Okuguquguqukayo okukhulu kakhulu ekunqumeni ukusebenza kwesistimu yamapayipi ukuthi ipayipi lifakwa kanjani. Ngisho nesistimu ekahle ingahluleka uma ifakwe ngokungalungile.
Ukunaka imininingwane kanye nokuhlela okuncane kuhamba ibanga elide ekutholeni indlela yokufaka efanele. Abantu bazomangala lapho bebona ukuthi kungakanani ukugeleza komoya okungatholakala ku-ducting eguquguqukayo ngokukhipha umnyombo oweqile nama-kinks bese wengeza i-hanger. Ukusabela kwe-reflex ukuthi umkhiqizo unecala, hhayi isifaki esisetshenziswayo. Lokhu kusiletha kusici seshumi.
Ukuqinisekisa ukuklama okuphumelelayo nokufakwa kwesistimu yamapayipi, kufanele iqinisekiswe. Lokhu kwenziwa ngokuqhathanisa idatha yokuklama nedatha elinganiswa ngemva kokufakwa kwesistimu. Izilinganiso zokugeleza komoya zegumbi ngalinye emakamelweni anesimo sezulu kanye nokushintsha kwezinga lokushisa emiseleni yizilinganiso ezimbili eziyinhloko okudingeka ziqoqwe. Wasebenzise ukuze unqume inani lama-BTU alethwe esakhiweni kanye nokuqinisekisa ukuthi izimo zokuklama ziyahlangatshezwana nazo.
Lokhu kungabuyela kuwe uma uthembele endleleni yakho yokuklama, ucabanga ukuthi uhlelo luziphatha ngendlela elindelekile. Ukulahlekelwa ukushisa/ukuzuza, ukukhethwa kwemishini nokubalwa komklamo wamapayipi akuhloselwe ukuqinisekisa ukusebenza - hhayi ngaphandle komongo. Kunalokho, zisebenzise njengeziqondiso zezilinganiso zenkambu zamasistimu afakiwe.
Ngaphandle kokunakekelwa, ukusebenza kwesistimu yakho yamapayipi kuzokwehla ngokuhamba kwesikhathi. Cabanga ukuthi ukulimala kwemigudu yomoya evela kosofa noma izintambo ezincike ezindongeni ezisemaceleni ziphazamisa kanjani ukugeleza komoya—ukubona kanjani lokho?
Qala ukulinganisa nokurekhoda ingcindezi yakho enganyakazi kukholi ngayinye. Ngemva kokuqinisekisa ukuthi uhlelo lwamapayipi lusebenza kahle, lesi sinyathelo esiphindaphindayo sikuvumela ukuthi uqaphe noma yiziphi izinguquko. Lokhu kukuvumela ukuthi uhlale uxhumekile kuma-ductwork futhi kukunikeza ukuqonda okungcono kwezinkinga ezehlisa isithunzi ukusebenza kwesistimu yakho yokudonsa.
Lokhu kubuka kwezinga eliphezulu kokuthi lezi zici ezingu-10 zisebenza kanjani ndawonye ukuze kunqunywe ukusebenza kwesistimu yamapayipi kuhloselwe ukukwenza ucabange.
Zibuze ngobuqotho: yiziphi kulezi zici ozinakayo, futhi yiziphi okufanele uzinake?
Sebenza kulezi zici zamapayipi ngesikhathi esisodwa futhi kancane kancane uzoba umdayisi omfushane. Wafake ekusetheni kwakho futhi uzothola imiphumela okungekho omunye ongayifanisa.
