Hauv lub tshuab cua txias, qhov kub thiab txias ntawm cov khoom siv cua txias thiab qhov siab ntawm cov khoom siv cua txias yog ib qho ua haujlwm ntawm ib leeg.
Nws muaj feem cuam tshuam nrog ntau yam mob xws li lub peev xwm ntawm lub compressor. Yog tias ib qho ntawm cov mob hloov pauv, qhov kub thiab txias ntawm cov dej noo thiab lub siab ntawm cov dej noo ntawm lub tshuab tub yees yuav hloov pauv raws li. Hauv BZL-3 × 4 lub tshuab cia khoom txias
, thaj chaw evaporation tsis tau hloov pauv, tab sis nws lub peev xwm tub yees tau ob npaug, uas ua rau lub peev xwm evaporation ntawm lub tshuab evaporator txias txav tau tsis sib xws nrog lub peev xwm nqus ntawm lub compressor (lub peev xwm evaporation Vo
Me dua li lub peev xwm nqus ntawm lub compressor (Vh), uas yog, V0
1. Qhov kev teeb tsa ntawm thaj chaw evaporation ntawm cov evaporator ntawm cov khoom siv cia khoom txias ua ke tsis tsim nyog:
Qhov kev teeb tsa ntawm thaj chaw evaporation ntawm lub evaporator hauv qhov chaw cia khoom txias ua ke yog txawv ntawm qhov kev xav tau ntawm cov txheej txheem tub yees tiag tiag. Raws li kev soj ntsuam ntawm qee qhov chaw cia khoom txias ua ke, thaj chaw evaporation ntawm lub evaporator tsuas yog
Muaj li ntawm 75% uas yuav tsum tau teeb tsa. Peb paub tias rau qhov kev teeb tsa ntawm lub evaporator hauv qhov chaw cia khoom txias ua ke, kev suav ntawm ntau yam cua sov yuav tsum tau ua raws li nws cov kev xav tau kub tsim, thiab lub peev xwm evaporation ntawm lub evaporator yuav tsum tau txiav txim siab.
Thaj chaw plaub hau, thiab tom qab ntawd teeb tsa raws li qhov yuav tsum tau ua ntawm cov txheej txheem tub yees. Yog tias lub evaporator tsis tau teeb tsa kom zoo raws li qhov yuav tsum tau tsim thiab thaj chaw teeb tsa ntawm lub evaporator raug txo qis, lub evaporator ntawm qhov chaw cia khoom txias ua ke yuav raug puas tsuaj.
Tus coefficient txias ib chav tsev poob qis heev thiab qhov load txias nce ntxiv, thiab qhov piv ntawm kev siv hluav taws xob txo qis heev, ua rau qhov kub thiab txias hauv qhov chaw khaws khoom txias qeeb qeeb, thiab tus coefficient ua haujlwm ntawm lub tub yees feem ntau nce siab.
Yog li ntawd, thaum tsim thiab xaiv cov evaporator ntawm qhov chaw cia khoom txias, thaj chaw ntawm cov evaporator yuav tsum tau xaiv raws li qhov sib txawv ntawm qhov kub hloov pauv zoo tshaj plaws.
2. Qhov kev teeb tsa ntawm lub tub yees ntawm cov khoom siv cia khoom txias ua ke tsis tsim nyog:
Cov chav tub yees uas tau teeb tsa rau ntawm qhov chaw cia khoom txias ua ke uas qee cov chaw tsim khoom tsim tsis suav raws li tag nrho cov khoom txias uas suav raws li kev tsim ntawm qhov chaw cia khoom thiab qhov tuab ntawm cov txheej rwb thaiv tsev ntawm cov qauv chaw cia khoom txias.
Kev faib nyiaj tsim nyog, tab sis txoj kev nce tus naj npawb ntawm cov tub yees kom ua tau raws li qhov xav tau ntawm kev txias sai hauv lub tsev rau khoom. Siv BZL-3 × 4 prefabricated txias cia ua piv txwv, qhov chaw cia khoom yog 4 meters ntev, 3 meters dav, thiab
2.7 meters, qhov ntim ntawm lub tsev rau khoom yog 28.723 cubic meters, nruab nrog 2 pawg ntawm 2F6.3 series tub yees thiab 2 pawg ntawm cov evaporators serpentine lub teeb raj ywj pheej, txhua chav tsev thiab ib qho evaporator ywj pheej tsim ib qho
Lub tshuab ua kom txias tiav rau kev ua haujlwm txias. Raws li kev kwv yees thiab kev tshuaj xyuas ntawm lub tshuab thauj khoom ntawm qhov chaw cia khoom txias, nws tuaj yeem paub tias lub tshuab thauj khoom ntawm qhov chaw cia khoom txias nquag yog li 140 (W / m3), thiab tag nrho cov khoom thauj tiag tiag yog
4021.22 (W) (3458.25kcal), raws li cov ntaub ntawv saum toj no, lub tshuab cia khoom txias xaiv lub tshuab txias 2F6.3 series (lub peev xwm txias txheem 4000kcal / h) kuj tseem tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub tshuab cia khoom txias.
Cov kev cai ntawm cov txheej txheem txias (txog li -15 ° C ~ -18 ° C), yog li ntawd, nws tsis tsim nyog los teeb tsa ib lub tub yees ntxiv rau ntawm lub tsev rau khoom, thiab nws tseem yuav ua rau tus nqi kho ntawm lub tsev nce ntxiv.
