Iphaneli yesandwichizisombululo zidlala indima ebalulekileyo kwiindawo zokugcina izinto ezibandayo, iifektri zesakhiwo sentsimbi, kunye neendawo zokuhambisa izinto, apho ukusebenza kobushushu kunye nokhuseleko lomlilo kuchaphazela ngokuthe ngqo iindleko zamandla kunye nokusebenza kwexesha elide. Ukukhetha izinto ezifanelekileyo akulula. Abakhi be-EPC kunye nabaphuhlisi kufuneka balinganise ukuthobela umlilo, ukusebenza kakuhle kobushushu, kunye nohlahlo-lwabiwo mali lweprojekthi. Phakathi kweendlela ezininzi, i-PIR kunye noboya belitye zihlala zizezona zinto zisetyenziswa kakhulu kwiphaneli ezigqunyiweyo kulwakhiwo lwanamhlanje.
Isixhobo ngasinye sinamandla kunye nemida ecacileyo. Ukukhetha okufanelekileyo kuxhomekeke kuhlobo lweprojekthi, iimfuno zovavanyo lomlilo, kunye neemeko zokusingqongileyo. Endaweni yokubuza ukuba yeyiphi engcono, abenzi bezigqibo kufuneka bagxile kwisisombululo esifanelekileyo kwiprojekthi.
Isicwangciso sokuSebenza kunye nokuThotyelwa kweMithetho ngoKhuseleko loMlilo
Ukhuseleko lomlilo ludla ngokuba yinto ephambili kwiiprojekthi ezinkulu. Uboya belitye bunika ukusebenza okuqinileyo kule ndawo. Njengezinto ezingaphiliyo, bufikelela kudidi lwe-A1 olungatshiyo phantsi kwemigangatho efana ne-EN 13501. Abutshisi okanye bukhuphe umsi onetyhefu kwiimeko zomlilo. Oku kubenza bufaneleke kwiindawo ezinomngcipheko ophezulu ezifana neendawo zokugcina izinto ezibandayo, izakhiwo zamayeza, kunye nezityalo ezinkulu zoshishino. Kwimimandla efana neRashiya kunye neMntla Yurophu, iinkqubo ezivalekileyo zeendawo zokugcina izinto okanye iifektri zihlala zisebenzisa iipaneli zesandwich zoboya belitye kuba zinokubonelela ngokhuseleko kunye nokukhusela umlilo.
I-PIR, njengezinto zokukhusela umlilo eziphilayo, inika ukumelana okulinganiselweyo komlilo xa kuthelekiswa noboya belitye. Ihlala ihlangabezana nohlobo lwe-B-s1, d0 okanye olunye olufana nalo, kuxhomekeke kwindlela eyenziwe ngayo kunye noyilo lwenkqubo. Kwimeko yomlilo, inokubola kwaye ikhuphe umsi. Ngenxa yesi sizathu, iiphaneli zokukhusela umlilo ze-PIR zihlala zifuna amanyathelo ongezelelweyo okukhusela umlilo. Oku kuquka izithintelo zomlilo, iingubo zokukhusela, okanye iinkqubo zokutshiza ukuze kuhlangatyezwane nokuthobela iprojekthi.
Kwimisebenzi yobunjineli bokwenyani, izisombululo ezixutyiweyo zixhaphakile. Abakhi badla ngokudibanisa iiphaneli ze-PIR kunye nezithintelo zomlilo ze-rock wool ukuze balinganisele ukhuseleko lomlilo kunye nokhuseleko lomlilo. Le ndlela iphucula ukuthotyelwa komthetho ngelixa igcina ukusebenza kwamandla kusebenza kakuhle. Amaqhinga oyilo lomlilo acacileyo kunye nokuhlanganiswa kwenkqubo ngokufanelekileyo kubalulekile ukuze kuvunywe kwaye kufuneke i-inshurensi.
Ukusebenza kakuhle kobushushu kunye neemeko zokusetyenziswa
Ukusebenza kobushushu yenye into ebalulekileyo ekukhetheni iiphaneli zesandwich. I-PIR inikezela ngokuhanjiswa kobushushu okuphantsi, ngesiqhelo malunga ne-0.022–0.024 W/(m·K). Oku kuvumela ubukhulu bephaneli obuncinci kwithagethi efanayo yokufakelwa. Inceda ukunciphisa ukusetyenziswa kwezinto kunye nokwandisa indawo yangaphakathi, nto leyo ibalulekileyo kwiindawo zokugcina izinto ezibandayo kunye neendawo zokugcina izinto ezilawulwa bubushushu.
Iiphaneli zoboya belitye zibonisa ukuhanjiswa kobushushu okuphezulu, ngesiqhelo phakathi kwe-0.036–0.040 W/(m·K). Oku kuthetha ukuba iindonga ezityebileyo ziyafuneka ukuze kufikelele kwinqanaba elifanayo lokukhusela. Nangona kunjalo, uboya belitye busebenza kakuhle phantsi kwamaqondo obushushu aphezulu kwaye bugcina ubungakanani obuzinzileyo ngokuhamba kwexesha. Ikwabonelela ngokukhusela okuhle kwe-acoustic kunye nokumelana neemeko zoshishino ezinzima.
Ukusebenza komswakama kufanele kuqwalaselwe. I-PIR inesakhiwo esivaliweyo esimelana nokungena komswakama. Uboya belitye bufuna ukutywinwa okufanelekileyo kunye nemiqobo yomphunga ukuze kugcinwe ukusebenza kwayo kwiimeko ezifumileyo. Ke ngoko, uyilo lweprojekthi kufuneka lubandakanye inkqubo epheleleyo yemvulophu yokwakha endaweni yokugxila kwizinto zodwa.
Icebo lobuchwephesha lepaneli yesandwich alixhomekekanga kwisixhobo esinye. Lidibanisa ukhuseleko lomlilo, iithagethi zobushushu, kunye nemida yeprojekthi ibe sisisombululo esinye. Ngokusebenzisa iipaneli ezigqunyiweyo okanye iinkqubo zepaneli ezidityanisiweyo ngendlela ecwangcisiweyo, abakhi banokufezekisa zombini ukuthobela kunye nokusebenza kakuhle. Le ndlela inciphisa umngcipheko, ilawula iindleko, kwaye ixhasa impumelelo yeprojekthi yexesha elide.
