Kunezinhlobo eziningi zengilazi emakethe, ngaphezu kokunaka kakhuluukusebenza kokuphepha kwengilazi, amehlo abantu abaningi futhi agxileukonga amandla engilazi, ake siqonde ukuthi singakhetha kanjani ingilazi efanelekile ukuze ifakwe futhi isetshenziswe ezindaweni ezahlukene zesimo sezulu?
Imingcele yokonga amandla yengilazi inezinkomba ezimbili, inani le-SC le-shading coefficient kanye ne-coefficient yokudlulisa ukushisa kwenani lika-K, yiziphi kulezi zinkomba ezimbili zomnikelo wokulondoloza amandla okwakhiwa kuncike esimweni sezulu sesakhiwo endaweni, kodwa futhi kuncike. ekusetshenzisweni komsebenzi wokwakha.
I-SC: I-Shading Coefficient, ebhekisela esilinganisweni sengqikithi yokudluliswa kwelanga kwengilazi kuleyo ye-3mmingilazi esobala ejwayelekile. (Inani letiyori le-GB/T2680 ngu-0.889, futhi izinga lamazwe ngamazwe ngu-0.87) ukubala, SC=SHGC÷0.87 (noma 0.889). Njengoba igama liphakamisa, yikhono lengilazi ukuvimba noma ukumelana namandla elanga, futhi i-shading coefficient SC value yengilazi ibonisa ukudluliswa kokushisa kwemisebe yelanga ngengilazi, kuhlanganise nokushisa ngokusebenzisa imisebe yelanga eqondile kanye nokushisa. elikhazimulayo ekamelweni ngemva kokuba ingilazi imunca ukushisa. Inani eliphansi le-SC lisho ukuthi amandla elanga amancane akhishwa ngengilazi.
Inani le-K: i-coefficient yokudlulisa ukushisa kwengxenye yengilazi, ngenxa yokudluliswa kokushisa kwengilazi kanye nomehluko wokushisa wangaphakathi nangaphandle, ukudluliswa kokushisa komoya okwenziwe komoya. Amayunithi ayo aseBrithani yilawa: amayunithi ashisayo aseBrithani ngonyawo lwesikwele ngehora ngeFahrenheit ngayinye. Ngaphansi kwezimo ezijwayelekile, ngaphansi komehluko othile wezinga lokushisa phakathi kwezinhlangothi ezimbili zengilazi ye-vacuum, ukushisa kudluliselwa kolunye uhlangothi ngesikhathi seyunithi ngendawo yeyunithi. Amayunithi e-metric yenani lika-K ngu-W /㎡·K. I-coefficient yokudlulisa ukushisa ayihlobene kuphela nezinto ezibonakalayo, kodwa futhi nenqubo ethile. Ukuhlolwa kwevelu ye-K yase-China kusekelwe ezingeni lase-China le-GB10294. Ukuhlolwa kwevelu ye-European K kusekelwe ezingeni laseYurophu le-EN673, futhi ukuhlolwa kwevelu ye-U yase-American kusekelwe ezingeni le-American ASHRAE, futhi izinga le-American ASHRAE lihlukanisa izimo zokuhlola yenani lika-U ebusika nasehlobo.
Izinga lokuklama ukongiwa kwamandla wokwakha linikeza inkomba yokukhawulela yeminyango kanye neWindows nomaikhethini lengilaziizindonga ngokwezifunda zezulu ezahlukene. Ngaphansi kwesisekelo sokuhlangabezana nale nkomba, ingilazi enenani eliphansi le-SC ene-shading coefficient kufanele ikhethwe ezindaweni lapho ukusetshenziswa kwamandla okupholisa umoya kubala ingxenye enkulu. Isibonelo, ezindaweni ezinehlobo elishisayo nobusika obufudumele, ucwaningo lubonisa ukuthi ukusetshenziswa kwamandla okubangelwa imisebe yelanga kubala cishe u-85% wokusetshenziswa kwamandla onyaka kule ndawo. Ukusetshenziswa kwamandla kokudluliswa kokushisa komehluko wezinga lokushisa kubalelwa ku-15% kuphela, ngakho-ke kusobala ukuthi indawo kufanele ikhulise umthunzi ukuze ithole umphumela ongcono kakhulu wokonga amandla.
Izifunda ezinengxenye enkulu yokusetshenziswa kwamandla okushisa kufanele zikhethe ingilazi ene-coefficient yokudlulisa ukushisa ephansi, njengezifunda ezibandayo ezinesikhathi esifushane sasehlobo, isikhathi eside sasebusika kanye nezinga lokushisa eliphansi langaphandle, ukwahlukanisa sekuphenduke ukuphikisana okuyinhloko, futhi inani eliphansi lika-K lisiza kakhulu ukonga amandla. Eqinisweni, kungakhathaliseki ukuthi yisiphi isifunda sezulu, inani eliphansi le-K ngokungangabazeki lingcono, kodwa ukwehlisa inani lika-K futhi kuyindleko, uma kubalwa ingxenye encane yeminikelo yokonga amandla akudingekile ukuphishekela. unganikezi imali mahhala.
Kungaphethwa ngokuthi ukwehla kwenani le-K, ngcono ukusebenza kokufakwa kwe-insulation, kanye negalelo layo ekwakheni ukongiwa kwamandla kancane kancane liyehla lisuka enyakatho liye eningizimu, nokuthi ukuthi lidinga ukwehla lingabhekwa ngokwezici zezindleko ngaphansi kwesisekelo sokuthi ukuhlangabezana nezidingo zamazinga okonga amandla. Ukwehla kwe-coefficient ye-shading SC, kunenzuzo ekongeni amandla ehlobo, kodwa kuyingozi ekongeni amandla ebusika. Kukhona ukuphikisa okwengeziwe mayelana nokuthi izakhiwo zokuhlala ehlobo elishisayo nezindawo zasebusika ezibandayo kanye nezakhiwo zomphakathi ezindaweni ezibandayo kufanele zibe yi-sunshade eyengeziwe, engahlaziywa ngokusho komsebenzi wokusetshenziswa kwesakhiwo, kanye nezinzuzo zidlula ukubi.
Nakuba i-SC inenani eliphansi, amandla e-sunshading anamandla, ngcono ukusebenza kokuvimbela imisebe yokushisa kwelanga ekamelweni. Kodwa-ke, uma uphishekela ngobumpumputhe inani eliphansi le-SC, ukukhanya kuncane, ukukhanya kwangaphakathi kuyancipha, ingilazi iba mnyama. Ngakho-ke, kufanele futhi sicabangele umthelela ohlangene weukukhanya, usayizi,umsindonezinye izici ukuze bathole eyabo ingilazi yokonga amandla.
