Mu mapangidwe a firiji ndondomeko, poganizira makhalidwe a refrigeration sing'anga ntchito, ntchito Mwachangu firiji mkombero ndi kusatsimikizika zinthu zachilengedwe, mawerengedwe adzakhala ovuta kuthetsa, amene ndi vuto kusintha ntchito pansi pa zinthu zosatsimikizika kuphunzira mu izi. pepala.
Gulu lofufuza la Pulofesa Zhu Lingyu ku Sukulu ya Chemical Engineering lidapereka njira yosinthira gridi yabwino yosakasaka m'derali kuti afufuze mufiriji wogwiritsa ntchito mphamvu zambiri komanso kusinthasintha kwapanthawi yogwirira ntchito kuti azitha kukhathamiritsa munthawi yomweyo ndikugwiritsa ntchito sing'anga poganizira kusinthasintha kwa magwiridwe antchito pansi pamikhalidwe yosatsimikizika.
Njira yamankhwala imakhudzidwa mosavuta ndi zinthu zosiyanasiyana zosatsimikizika pakugwira ntchito kwenikweni ndikupatuka kumayendedwe abwino kwambiri.Zokayikitsa izi makamaka zimachokera ku mbali zitatu :(1) kusatsimikizika kwa magawo omwe amagwiritsidwa ntchito popanga njira;(2) kusatsimikizika kwa zinthu zamkati (monga kutentha ndi misa kutengerako coefficient ndi mlingo anachita);(3) Kusatsimikizika kwa zinthu zakunja za njirayi, monga momwe amadyera, kutentha kozungulira ndi kupanikizika, komanso kufunikira kwa msika wazinthu.
Kusinthasintha kwa kayendetsedwe ka kayendetsedwe ka mankhwala kungathe kufotokozedwa ndi dera lotheka mu malo osadziwika a parameter.MU ZOTHANDIZA ZOTHANDIZA, zofunikira zamatchulidwe azinthu, chuma ndi chitetezo zimakhutitsidwa nthawi zonse pamene zosintha zowongolera zimasinthidwa mwakufuna.Choyamba, chigawo chotheka chimatsimikiziridwa, ndiyeno kusinthasintha kwa dongosolo la ndondomeko kumawerengedwanso ndi chiwerengero chachikulu cha makulitsidwe malinga ndi hyperrectangle yamkati kapena flexibility index based on hypervolume ratio.
Pepalali likupereka njira yosungira bwino zidziwitso zamalumikizidwe a gridi pogwiritsa ntchito mindandanda yolumikizidwa yamitundu iwiri, ndikugwiritsa ntchito njira yofananira yosokoneza kuti iyeretse ndikupeza malire omwe angatheke.Nthawi yomweyo, njirayi imathandizira kuwerengera kwachindunji kwa hypervolume yotheka ndi kuchuluka kwa ma hypercubes otheka mu gridi, popanda kugwiritsa ntchito njira zomanganso mawonekedwe.Njira yofufuzira ya gridi yomwe ikuyembekezeredwa ingathe kujambula mawonekedwe ovuta a chigawocho, kuchepetsa mtengo wa zitsanzo komanso kusakhala mwachisawawa.

Njirayi idagwiritsidwa ntchito pagawo limodzi lokhala ndi mpweya wopopera firiji, ndipo kukhathamiritsa kwa refrigerant kothandizidwa ndi makompyuta kunkachitika kuti kupititse patsogolo kusinthasintha kwa magwiridwe antchito ndi mphamvu zamagetsi, komanso kugawa kwa refrigerant kutengera kusinthasintha ndi kukhathamiritsa kwamphamvu kunasankhidwa.
Flexible pazipita sing'anga ntchito kwa single siteji nthunzi compression firiji mkombero
Zotsatira za "Njira yowunikira yoyengedwa ya gridi yowunika kusinthasintha kwa magwiridwe antchito ndikugwiritsa ntchito pa Kusankha kwa firiji" idasindikizidwa mu AIChE Journal.Wolemba woyamba ndi Jiayuan Wang, Mphunzitsi wa Sukulu ya Chemical Engineering, wolemba wachiwiri ndi Robin Smith, Pulofesa wa yunivesite ya Manchester, UK, ndipo wolembayo ndi Lingyu Zhu, Pulofesa wa Sukulu ya Chemical Engineering.
AIChE Journal ndi imodzi mwazolemba zotsogola kwambiri pamakampani opanga mankhwala padziko lonse lapansi, zomwe zimafotokoza za kafukufuku wofunikira komanso waposachedwa kwambiri pazaumisiri wamankhwala ndi maphunziro ena okhudzana ndi uinjiniya.
