Zomwe zimapangidwazo ndi zaukadaulo wa zida zamafiriji, makamaka njira yopangira ma firiji a mafakitale.

Ukadaulo wakumbuyo:
Ntchito ya kompresa ndi kufinya nthunzi ndi kutsika kutsika mu nthunzi ndi kuthamanga kwambiri, kuti achepetse kuchuluka kwa nthunzi ndikuwonjezera kuthamanga.Compressor imayamwa sing'anga yogwira ntchito ndi kuthamanga kwapansi kuchokera ku evaporator, kumawonjezera kuthamanga ndikutumiza ku condenser.Imasungunuka kukhala madzi okhala ndi kuthamanga kwambiri mu condenser.Pambuyo throttling ndi throttle valavu, amakhala madzi ndi m'munsi kuthamanga, ndiyeno amatumiza kwa evaporator.Imayamwa kutentha mu evaporator ndikuwukira mu nthunzi ndi kupanikizika pang'ono, kenako imatumiza ku cholowera cha kompresa kuti amalize kuzungulira kwa firiji, Chifukwa cha kuchuluka kwa mafiriji, makina akulu amafiriji amafakitale nthawi zambiri amatengera njira ya firiji. kupitilira magawo awiri a kukanikizana ndi kuzizira kwapakati.Compressor ndiye mtima wozungulira firiji, ndipo kapangidwe kake koyenera ndikofunikira kwambiri.Chifukwa chake, pamayendedwe a firiji omwe amagwiritsidwa ntchito kwambiri m'mafakitale, poganizira zocheperako za firiji, mphamvu ya kompresa ndi kapangidwe kake, kupanga mkombero wafiriji wabwino kwambiri wokhala ndi firiji yabwino, kapangidwe koyenera komanso kugwiritsa ntchito mphamvu pang'ono ndiye njira yachitukuko ya kapangidwe ka firiji yamafakitale.M'zochita, njira yanthawi zonse ya refrigeration standard yachikhalidwe chadziko lonse imatengedwa.

Woyambitsayo adapeza kuti pali zolakwika zotsatirazi pazojambula zam'mbuyomu:
M'zochita, njira yopangira zaluso zam'mbuyomu imakhala ndi mapangidwe ovuta komanso zofunika kwambiri za kompresa, ndipo makina a firiji ndi kompresa nthawi zambiri amapangidwa ndi akatswiri osiyanasiyana opanga.Nthawi zambiri, muyeso wa mapangidwe amawerengedwa molingana ndi kuchuluka kwa firiji, ndipo magawo apangidwe a kompresa amatsimikiziridwa molingana ndi mfundo yowerengera ya refrigeration coefficient mawerengedwe amakwaniritsa zofunikira zamapangidwe, koma sangathe kukwaniritsa zofunikira zachuma;Ngati mapangidwe osakhala ovomerezeka atengedwa, mapangidwe ndi kupanga mapangidwe a compressor ndiatali ndipo mphamvu yake ndi yochepa, zomwe zingayambitse kusagwirizana pakati pa kompresa ndi dongosolo la ndondomeko ndipo sangathe kukwaniritsa zofunikira zozizira za firiji.
Poganizira izi, zomwe zidapangidwa pano zikuperekedwa.
