Ngokubhekiselele kwizinto zamandla, zinokuhlengahlengiswa ngokuthanda ukusuka ku-1 ukuya ku-1.
4. Uyilo oluzimeleyo lokutshatyalaliswa kobushushu. Imodyuli ithatha ulwakhiwo olunqamlekileyo lokuhlukanisa iziko lolawulo oluphambili kunye nezinto eziphambili zokufudumeza; i-air duct ezimeleyo isetyenziselwa ukuqinisekisa ukuba i-cavity yomoya inomoya owaneleyo woxinzelelo. Xa kuthelekiswa nomxube womoya odibeneyo, uyilo lwe-thermal lungcono.
Ingxoxo malunga nokusetyenziswa kokugcinwa kwe-optical edibeneyo kunye neteknoloji yokutshaja
Imowudi yesicelo eqhelekileyo yokugcina i-optical kunye nokutshaja yimowudi ye-AC microgrid. I-architecture yayo ephambili ibandakanya ibhasi ye-AC, i-photovoltaics, iimfumba zokutshaja, ukugcinwa kwamandla kunye neebhetri, njl. Inkqubo inokuxhotyiswa ngezixhobo zokutshintshela ngaphandle kwegridi yokutshintsha ngokungenamthungo.
Ukusetyenziswa kokugcinwa kwe-optical kunye nokutshaja kuya kuphuhlisa ibe yimeko yokuncedisa amandla amaninzi kwixesha elizayo. Kwixesha elizayo, kungekhona kuphela i-photovoltaics kunye nokugcinwa kwamandla, kodwa kunye nemithwalo ye-thermal, iimpompo zokushisa, imithombo yamandla asasazwayo, njl.
