Tshuab cua txias lub tshuab raj evaporator
1.Cov khoom yeeb nkab
Lub raj cua txias yog lub tshuab evaporator siv los ua cua txias. Cov khoom siv dav siv hauv cov tub yees txias, lub tshuab ua kom cov dej txias thiab yaj hauv cov yeeb nkab txias, thiab cov cua txias sab nraum cov yeeb nkab ua cov cua sov ua kom muaj qhov nruab nrab rau kev sib tw ntawm ntuj.
Qhov loj tshaj plaws ntawm cov kav dej txias yog tias cov qauv tsim tau yooj yim, yooj yim rau kev tsim khoom, thiab kev noj qhuav ntawm cov khoom noj tsis ua hauj lwm khaws cia hauv lub tsev rau khoom yog tsawg dua. Txawm li cas los xij, lub tshav kub hloov coefficient ntawm cov yeeb nkab yog tsawg, thiab kev khiav haujlwm nyuaj thaum defrosting, uas tsis yog qhov yooj yim rau kev siv tshuab. Rau qhov ncaj qha qhov system txias ntawm ammonia, txoj hlua khi steel hlau yog welded, thiab lub teeb xa hluav taws xob lossis cov raj finned siv; rau lub kaw lus Freon, cov winding daim lossis lub tes tsho hom tooj liab tube fin tube teeb feem ntau siv.
2. Cov raj raj hom raj
Lub coiled yeeb nkab jacking lub ntiajteb txawj nqus pub mis lossis ammonia twj tso kua mis pub kua tuaj yeem siv; cov kab nkaus xwb thiab ob chav kab serpentine phab ntsa yeeb nkab tuaj yeem siv rau qhov qis dua sab hauv thiab qhov hluav taws xob ammonia twj tso kua hluav taws xob cov kua dej thiab lub zog nqus kua system, rau cov coil tube kab lub raj kuj tseem siv tau rau lub zog ntawm ammonia twj tso kua mis nce thiab nqis system thiab cov thermal expansion valve muab kev kaw lus.
Qhov zoo ntawm cov coiled raj yog tias tus qauv yooj yim, yooj yim rau kev tsim khoom, tus nqi ntawm cov khoom ua kua tau tsawg, thiab kev siv yog muaj zog. Lub ntsiab kev cuam tshuam tseem ceeb yog tias cov pa luam tawm nyob rau hauv qis ntawm lub yeeb nkab tsis tuaj yeem nqa tawm hauv lub sijhawm, thiab yuav tsum tau tawm tom qab tag nrho ntawm cov yeeb nkab, yog li cov cua sov hloov coefficient yog me me, thiab vapor-kua ob- theem ntws tsis kam yog loj.
3. Lub raj u-puab
Cov kheev siv U-zoo li tus kav yog tsim ntawm ob lossis plaub txheej txheej ntawm cov hlau tsis muaj hau hlau.
U-puab lub raj xaib sab saum toj muaj qhov zoo ntawm cov huab cua tsis sib haum, kev npaj yooj yim thiab kev teeb tsa, thiab cov kua dej me me rau qhov tso nyiaj, kwv yees li 50% ntawm nws lub ntim. Nws yog qhov tsim nyog rau lub ntiajteb txawj nqus noj system thiab ammonia twj tso kua mis nkag mus thiab tawm hauv ammonia tub yees kev kaw lus hauv lub thawv txias. Tau txais kev siv ntau yam. Txawm li cas los xij, nws muaj chaw ntau dua rau kev ua lub tsev rau khoom, thiab lub raj xa dej sab sau tsis yooj yim rau defrost.
