Kwinkqubo yokukhenkcisa, ubushushu bokufuma kunye noxinzelelo lokufuma zizinto ezihambelanayo.
Inxulumene neemeko ezahlukeneyo ezifana nomthamo wecompressor. Ukuba enye yeemeko iyatshintsha, iqondo lobushushu bokufuma kunye noxinzelelo lokufuma kwenkqubo yokukhenkceza ziya kutshintsha ngokufanelekileyo. Kwindawo yokugcina ebandayo eshukumayo ye-BZL-3×4
, indawo yokufuma ayikatshintshi, kodwa amandla ayo efriji aphindwe kabini, nto leyo eyenza amandla okufuma e-evaporator yokugcina izinto ezibandayo angahambelani namandla okufunxa e-compressor (amandla okufuma e-Vo).
Incinci kakhulu kunomthamo wokufunxa wecompressor (Vh), oko kukuthi, i-V0
1. Uqwalaselo lwendawo yokufuma yesixhobo sokugcina ubushushu esidibeneyo alunangqiqo:
Indlela ebekwe ngayo indawo yokufuma ye-evaporator kwindawo yokugcina ebandayo edibeneyo yahlukile kakhulu kwiimfuno zobugcisa zenkqubo yokwenyani yokufunxa. Ngokwezinto ezibonwe kwindawo yokugcina ebandayo edibeneyo, indawo yokufuma ye-evaporator yenzelwe kuphela.
Kukho malunga ne-75% ekufuneka icwangciswe. Siyazi ukuba ukuze kulungiselelwe i-evaporator kwindawo yokugcina ebandayo edibeneyo, ukubalwa kwemithwalo eyahlukeneyo yobushushu kufuneka kwenziwe ngokweemfuno zobushushu boyilo lwayo, kwaye amandla okuphuma komphunga we-evaporator kufuneka amiselwe.
Indawo yeenwele, uze uyilungiselele ngokweemfuno zenkqubo yokukhenkcisa. Ukuba i-evaporator ayilungiselelwanga ngokufanelekileyo ngokweemfuno zoyilo kwaye indawo yokumisela ye-evaporator incitshiswe ngokungabonakaliyo, i-evaporator yendawo yokugcina ebandayo edibeneyo iya konakala.
I-coefficient yokupholisa ngokwendawo nganye yeyunithi iyehla kakhulu kwaye umthwalo wokupholisa uyanda, kwaye umlinganiselo wokusebenza kwamandla uyehla kakhulu, nto leyo ebangela ukwehla kancinci kobushushu kwindawo yokugcina izinto ezibandayo ezishukumayo, kwaye i-coefficient yokusebenza kwefriji idla ngokunyuka.
Ke ngoko, xa uyila kwaye ukhetha i-evaporator yendawo yokugcina izinto ezibandayo eshukumayo, indawo ye-evaporator kufuneka ikhethwe ngokweenguqu zobushushu ezifanelekileyo.
2. Uqwalaselo lweyunithi yokukhenkceza yezixhobo zokugcina izinto ezibandayo ezidibeneyo alunangqiqo:
Iiyunithi zokukhenkcisa ezilungiselelwe kwindawo yokugcina ebandayo edibeneyo eyenziwe ngabanye abavelisi azibalwa ngokwenani elipheleleyo lomthwalo wokupholisa obalwa ngokwendlela yoyilo lwendawo yokugcina kunye nobukhulu bomaleko wokukhusela wesakhiwo esisebenzayo sendawo yokugcina ebandayo.
Ulwabiwo olufanelekileyo, kodwa indlela yokwandisa inani leeyunithi zefriji ukuhlangabezana neemfuno zokupholisa ngokukhawuleza kwindawo yokugcina impahla. Thatha indawo yokugcina ebandayo esele yenziwe ngaphambili ye-BZL-3×4 njengomzekelo, indawo yokugcina inobude beemitha ezi-4, ububanzi beemitha ezi-3, kwaye
Iimitha ezi-2.7, umthamo opheleleyo wendawo yokugcina impahla yi-28.723 cubic metres, ixhotyiswe ngeeseti ezi-2 zeeyunithi zokukhenkceza ze-2F6.3 series kunye neeseti ezi-2 zee-evaporators zetyhubhu yokukhanya ye-serpentine ezizimeleyo, iyunithi nganye kunye ne-evaporator ezimeleyo zenza i-
Inkqubo epheleleyo yokukhenkcisa ukuze kusebenze ukupholisa. Ngokwengqikelelo kunye nohlalutyo lomthwalo womatshini kwindawo yokugcina ebandayo, kuyaziwa ukuba umthwalo womatshini kwindawo yokugcina ebandayo esebenzayo umalunga ne-140 (W/m3), kwaye umthwalo opheleleyo wokwenyani ngu
4021.22(W) (3458.25kcal), ngokwedatha engentla, indawo yokugcina izinto ezibandayo ephathwayo ikhetha iyunithi yokukhenkceza ye-2F6.3 series (umthamo wokupholisa oqhelekileyo yi-4000kcal/h) inokuhlangabezana neemfuno zendawo yokugcina izinto ezibandayo ephathwayo.
Iimfuneko zenkqubo yokubanda (ukuya kuthi ga kwi -15°C ~ -18°C), ngoko ke, akunyanzelekanga ukumisela enye iyunithi yokukhenkceza kwindawo yokugcina impahla, kwaye kuya kunyusa neendleko zokugcinwa kweyunithi.
