Kapangidwe ndi kusanthula kwa chiller

Choyamba, zigawo za chiller, kompresa ndiye chigawo chachikulu cha chiller, ndipo mphamvu ya kinetic yoperekedwa ndi kompresa imathandizira kuti chiller azizungulira mosalekeza.

Compressor imagawidwa kukhala mbali yoyamwa komanso yotulutsa. Mbali yoyamwa imayamwa gasi mufiriji ndipo mbali yotulutsa imatulutsa mpweya wa refrigerant. Mu chipinda chogwirira ntchito cha kompresa, kompresa amapondereza mpweya wa refrigerant womwe umalowetsedwa mkati mwa mbali yoyamwa, ndiyeno mpweya wa refrigerant Udzakhala mpweya wotentha kwambiri komanso wothamanga kwambiri, womwe umatulutsidwa kumapeto kwa utsi.

Pambuyo pa mapeto a utsi ndi cholekanitsa mafuta, chomwe cholinga chake ndi ntchito yake ndikulekanitsa mafuta osungunuka omwe ali mufiriji, ndiyeno condenser. Firiji yoyera pambuyo pa kulekanitsa mafuta imalowa mu payipi ya condenser. Malingana ndi zozizira zosiyanasiyana, zimagawidwa m’magulu awiri: mpweya wozizira ndi madzi utakhazikika. Njira yochepetsera kutentha ndi kuchepetsa kutentha kwa ma condensers oziziritsidwa ndi mpweya ndi yosiyana ndi ya condensers yamadzi ozizira, koma onse alipo kuti achepetse.

Kaya ndi mpweya wozizira kapena madzi ozizira, kutentha kwa condenser nthawi zambiri kumakhala kokwera kwambiri panthawi yogwira ntchito komanso panthawi ya condensation, chifukwa condenser ndi chotenthetsera kutentha, chomwe chimagwiritsidwa ntchito kusinthanitsa kutentha, ndipo kutentha kumakakamizika. kuyenda mumlengalenga kapena kuzizira Madzi amatengedwa kuti aziziziritsa mufiriji.

Pambuyo pa condensing ndondomeko, refrigerant amakhala otsika kutentha ndi mkulu-kupanikizika madzi. The throttling ndi kuchepetsa kuthamanga chofunika pansipa. Chipangizo chochepetsera kuponderezana ndi kupanikizika ndi valavu yowonjezera kwa ambiri ozizira. Kunena zowona, ndi Thermal expansion valve.

The matenthedwe valavu kutambasuka akhoza kuweruza kukula kwa kutsegula ndi kutseka kutsegula molingana ndi kachipangizo kutentha pa mapeto a evaporator wa chiller, ndiyeno mulole refrigerant madzi a otaya kukula koyenera kulowa ndondomeko evaporator, ndi kuchepetsa kuthamanga pamene. kudutsa mu valve yowonjezera kutentha, ndiko kuti, Throttling ndi depressurization.

Refrigerant yamadzimadzi imadutsa mu evaporator, kusungunula ndi kuyamwa kutentha kuti ifike mufiriji, kenako kuyenda mumadzi kuti ibwerere ku kompresa (komanso kudutsa cholekanitsa chamadzimadzi cha gasi).
