Kwinkqubo yefriji, iqondo lokushisa elikhuphayo kunye noxinzelelo lwe-evaporating ngumsebenzi womnye nomnye.
Inxulumene neemeko ezininzi ezifana nomthamo wecompressor. Ukuba enye yeemeko iyatshintsha, ukushisa kwe-evaporation kunye noxinzelelo lwe-evaporation yenkqubo yefriji iya kutshintsha ngokufanelekileyo. Kwi-BZL-3 × 4 yokugcina ebandayo ehambayo
, indawo yokuphuphuma komphunga ayitshintshanga, kodwa umthamo wayo wefriji uphindaphindeke kabini, nto leyo eyenza ukuba umphunga womthamo we-evaporator oshenxisekayo wokugcina obandayo ungahambelani nomthamo wokufunxa wecompressor (umthamo wokuphuphuma komphunga Vo
Incinci kakhulu kunomthamo wokufunxa wecompressor (Vh), oko kukuthi, V0
1. Ulungelelwaniso lwendawo yokuphuphuma komphunga wesixhobo sokugcina esibandayo esidibeneyo akukho ngqiqweni:
Ubume bendawo yokuphuphuma komphunga kwindawo yokugcina ebandayo edibeneyo yahluke kakhulu kwiimfuno zobugcisa zenkqubo yefriji yokwenyani. Ngokoqwalaselo lwalapho kwezinye iindawo ezibandayo ezidityanisiweyo, indawo yokuphuphuma komphunga kuphela.
Kukho malunga ne-75% ekufuneka iqwalaselwe. Siyazi ukuba ukucwangciswa kwe-evaporator kwindawo yokugcina ebanda edibeneyo, ukubalwa kwemithwalo yobushushu eyahlukeneyo kufuneka kuqhutywe ngokweemfuno zayo zobushushu boyilo, kwaye umthamo wokunyuka kwe-evaporator kufuneka umiselwe.
Indawo yeenwele, kwaye emva koko ulungiselele ngokweemfuno zenkqubo yefriji. Ukuba i-evaporator ayicwangciswanga ngokufanelekileyo ngokweemfuno zoyilo kwaye indawo yoqwalaselo ye-evaporator iyancitshiswa ngokungaboniyo, i-evaporator yendawo yokugcina ebandayo iya konakaliswa.
I-coefficient yokupholisa kwindawo nganye yeyunithi yehla kakhulu kwaye umthwalo wokupholisa uyanda, kwaye umlinganiselo wokwanelisa amandla uyancipha kakhulu, okubangela ukuhla okucothayo kwiqondo lokushisa kwindawo yokugcina ebandayo, kwaye i-coefficient yokusebenza yefriji ivame ukunyuka.
Ke ngoko, xa uyila kwaye ukhetha i-evaporator yendawo yokugcina ebandayo, indawo ye-evaporator kufuneka ikhethwe ngokowona mahluko ubushushu bokuhambisa ubushushu.
2. Ukucwangciswa kweyunithi yesikhenkcezisi sesixhobo sokugcina esibandayo esidibeneyo akunangqiqo:
Iiyunithi zokukhenkceza ezicwangcisiweyo kugcino oludityanisiweyo oluveliswa ngabavelisi abathile azibalwa ngokomthwalo wokupholisa uwonke obalwa ngokoyilo logcino kunye nobukhulu bomaleko wokugquma wesakhiwo sogcino olubandayo olusebenzayo.
Ulwabiwo olunengqiqo, kodwa indlela yokwandisa inani leeyunithi zefriji ukuhlangabezana neemfuno zokupholisa ngokukhawuleza kwindawo yokugcina impahla. Thatha i-BZL-3 × 4 yokugcina ebandayo ekhethiweyo njengomzekelo, indawo yokugcina i-4 yeemitha ubude, i-3 yeemitha ububanzi, kwaye
Iimitha ezi-2.7, umthamo wenetha we-warehouse yi-28.723 cubic metres, ixhotyiswe ngeeseti ezi-2 ze-2F6.3 zeeyunithi zefriji kunye neeseti ezi-2 ze-evaporator ye-srpentine light evaporators ezimeleyo, iyunithi nganye kunye nefom ye-evaporator ezimeleyo
Gqibezela inkqubo yokukhenkceza ukuze usebenze ngokupholisa. Ngokoqikelelo kunye nohlalutyo lomthwalo womatshini wokugcinwa okubandayo, kuyaziwa ukuba umthwalo womatshini wokugcinwa okubandayo okusebenzayo malunga ne-140 (W / m3), kwaye owona mthwalo uphelele.
I-4021.22 (W) (3458.25kcal), ngokweenkcukacha ezingentla, ukugcinwa okubandayo okuhambahambayo kukhetha iyunithi yefriji ye-2F6.3 (umthamo oqhelekileyo wokupholisa 4000kcal / h) unokuhlangabezana neemfuno zokugcinwa okubandayo okuhambayo.
Iimfuno zenkqubo ebandayo (ukuya kuthi ga kwi -15 ° C ~ -18 ° C), ngoko ke, akufuneki ukuqwalasela enye iyunithi yefriji kwi-warehouse, kwaye iya kwandisa iindleko zokugcinwa kweyunithi.
