Kukho iintlobo ezininzi zeglasi kwimarike, ngaphezu kokunikela ingqalelo ngakumbiukusebenza kokhuseleko lweglasi, amehlo abantu abaninzi kwakhona igxile kwiukonga amandla eglasi, masiqonde indlela yokukhetha iglasi efanelekileyo yokufakela kunye nokusetyenziswa kwiindawo ezahlukeneyo zemozulu?
Iparameters zokonga amandla eglasi zinezalathi ezimbini, i-shading coefficient SC value kunye ne-heat transfer coefficient K ixabiso, zeziphi zezi zalathisi zibini kwigalelo logcino lwamandla okwakha kuxhomekeke kwiimeko zemozulu zesakhiwo kuloo ndawo, kodwa kukwaxhomekeke kusetyenziso lomsebenzi wokwakha.
I-SC: I-Shading Coefficient, ebhekiselele kumlinganiselo welanga lilonke lokugqithiswa kweglasi kuleyo ye-3mm.iglasi ecacileyo esemgangathweni. (Ixabiso lethiyori ye-GB/T2680 yi-0.889, kwaye umgangatho wamazwe ngamazwe ngu-0.87) ukubala, SC=SHGC÷0.87 (okanye 0.889). Njengoko igama libonisa, bubuchule beglasi ukubhloka okanye ukuxhathisa amandla elanga, kwaye i-shading coefficient ye-SC yeglasi ibonisa ukuhanjiswa kobushushu bemitha yelanga ngeglasi, kubandakanya nobushushu ngokuphuma ngqo kwelanga kunye nobushushu. kukhanya kwigumbi emva kokuba iglasi ifunxa ubushushu. Ixabiso eliphantsi le-SC lithetha ukuba amandla amancinci elanga asasazwa ngeglasi.
Ixabiso le-K: yi-coefficient yokudlulisa ubushushu becandelo leglasi, ngenxa yokuhanjiswa kobushushu beglasi kunye nokwahlukana kobushushu bangaphakathi nangaphandle, umoya owenziweyo ukuya kubushushu bomoya. Iiyunithi zayo zaseBritani zezi: Iiyunithi ze-thermal zaseBritane kwisikwere sonyawo ngeyure ngeFahrenheit. Ngaphantsi kweemeko ezisemgangathweni, phantsi komlinganiselo othile weqondo lokushisa phakathi kwamacala amabini eglasi ye-vacuum, ubushushu budluliselwe kwelinye icala ngexesha leyunithi ngokusebenzisa indawo yeyunithi. Iiyunithi zemetric zexabiso le-K ngu-W /㎡·K. I-coefficient yokudlulisa ukushisa ayihambelani kuphela kwizinto eziphathekayo, kodwa kunye nenkqubo ethile. Uvavanyo lwexabiso laseTshayina lwe-K lusekwe kumgangatho waseTshayina we-GB10294. Uvavanyo lwexabiso le-K yaseYurophu lusekelwe kumgangatho we-EN673 yaseYurophu, kwaye uvavanyo lwexabiso le-U laseMelika lusekelwe kumgangatho we-American ASHRAE, kunye nomgangatho we-ASHRAE waseMelika wahlula iimeko zovavanyo lwexabiso le-U ebusika nasehlotyeni.
Umgangatho woyilo logcino lwamandla okwakha ubonelela ngesalathiso sokunciphisa iingcango kunye neWindows okanyeikhethini yeglasiiindonga ngokwemimandla yemozulu eyahlukeneyo. Ngaphantsi kwesiseko sokuhlangana kwesi salathisi, iglasi ene-coefficient ephantsi ye-shading ye-SC kufuneka ikhethwe kwiindawo apho ukusetyenziswa kwamandla omoya kubangelwa umlinganiselo omkhulu. Ngokomzekelo, kwiindawo ezinehlobo elishushu kunye nobusika obufudumeleyo, uphando lubonisa ukuba ukusetyenziswa kwamandla okubangelwa yimitha yelanga kubalelwa malunga ne-85% yokusetyenziswa kwamandla ngonyaka kule ndawo. Ukusetyenziswa kwamandla okutshintshiselana kobushushu kwi-15% kuphela, ngoko kuyacaca ukuba indawo kufuneka yandise umthunzi ukuze ifumane eyona mpembelelo yonga amandla.
Imimandla enenxalenye enkulu yokusetyenziswa kwamandla okufudumeza kufuneka ikhethe iglasi ene-coefficient yokuhambisa ubushushu obuphantsi, njengemimandla ebandayo enexesha elifutshane lasehlotyeni, ixesha elide lasebusika kunye nobushushu obuphantsi bangaphandle, ukugquma kuye kwaba yeyona nto iphikisanayo, kwaye ixabiso elisezantsi le-K lifanelekile ngakumbi. ukonga amandla. Enyanisweni, kungakhathaliseki ukuba yeyiphi indawo yemozulu, ixabiso eliphantsi le-K ngokungathandabuzekiyo lingcono, kodwa ukunciphisa ixabiso le-K kukwayindleko, ukuba ibala umlinganiselo omncinci weminikelo yokonga amandla akufuneki ukuba ilandele, kunjalo, yenza. unganiki mali simahla.
Kunokugqitywa ukuba ixabiso eliphantsi le-K, ngcono ukusebenza kokufakelwa, kunye negalelo layo ekwakheni ugcino lwamandla ngokuthe ngcembe liyancipha ukusuka emantla ukuya emazantsi, kwaye ingaba kufuneka ibe ngaphantsi kunokuqwalaselwa ngokweendleko zexabiso phantsi kwesiseko ukuhlangabezana neemfuno zemigangatho yogcino lwamandla. Okusezantsi i-coefficient ye-shading ye-SC kukuba, kunenzuzo ukonga amandla ehlotyeni, kodwa kuyingozi ekongeni amandla ebusika. Kukho ukuchasana ngakumbi malunga nokuba izakhiwo zokuhlala kwiindawo ezishushu zasehlotyeni kunye neendawo zasebusika ezibandayo kunye nezakhiwo zikawonkewonke kwiindawo ezibandayo kufuneka zibe yi-sunshade eyongezelelweyo, enokuthi ihlalutywe ngokuhambelana nomsebenzi wokusetyenziswa kwesakhiwo, kunye neenzuzo zigqithise izinto ezingalunganga.
Nangona ixabiso eliphantsi le-SC, linamandla amandla okukhanya kwelanga, ngcono ukusebenza kokuthintela ukushisa kwemitha yelanga kwigumbi. Nangona kunjalo, ukuba ulandela ngokumfamekileyo elona xabiso lisezantsi le-SC, ukukhanya okuncinci, ukukhanya okuncinci kwangaphakathi, kokukhona iglasi imnyama. Ngoko ke, kufuneka siqwalasele impembelelo edibeneyo yeukukhanya, ubukhulu,ingxolokunye neminye imiba ukuze bafumane iglasi yabo yokonga amandla.
