Cov nyhuv ntawm defrost ntawm evaporator condenser
Tso lus
1.Cov nyhuv ntawm Frost ntawm lub tub yees system
Thaum lub tshuab cia txias txias ua haujlwm li qub, qhov kub ntawm lub evaporator yog qis dua li qhov dew point kub ntawm huab cua, thiab noo noo nyob rau hauv cov zaub mov thiab huab cua yuav precipitate thiab condense ntawm lub raj phab ntsa. Yog hais tias qhov kub ntawm cov yeeb nkab phab ntsa qis dua 0 degree, cov dej lwg yuav condense rau Frost. Frosting kuj yog ib qho txiaj ntsig ntawm kev ua haujlwm ntawm lub tub yees, yog li ib qho me me ntawm frosting tau tso cai rau saum npoo ntawm evaporator.
Vim tias cov thermal conductivity ntawm Frost tsawg dhau lawm, nws yog ib feem pua, lossis txawm tias ntau pua ntawm cov hlau, yog li cov txheej txheej Frost ua rau cov thermal kuj loj. Tshwj xeeb tshaj yog thaum lub Frost txheej yog tuab, nws yog zoo li thaum tshav kub kub preservation, yog li ntawd lub txias nyob rau hauv lub evaporator tsis yooj yim rau dissipate, uas cuam tshuam rau cov cua txias ntawm lub evaporator. Thaum kawg, qhov txias cia tsis tuaj yeem ncav cuag qhov kub thiab txias. Nyob rau tib lub sijhawm, evaporation ntawm cov tub yees hauv evaporator yuav tsum tsis muaj zog. Ua tsis tiav cov kua ammonia tuaj yeem nqus mus rau hauv lub compressor thiab ua rau cov kua rauj raug mob.
2. Qhov cuam tshuam ntawm defrosting ntawm ib puag ncig hauv zos
Muaj ntau txoj hauv kev rau defrost, xws li dag defrosting, refrigerant tshav kub melting, dej defrosting, hluav taws xob defrosting, thiab lwm yam. Rau cov tub yees me me, phau ntawv defrosting thiab hluav taws xob cua sov defrosting yuav siv tau. Tab sis nws yuav tsum tau ua thaum lub kaw lus poob. Rau cov tub yees loj dua, refrigerant kub-melt frosting thiab dej-melting frosting yuav tsum tau siv. Vim lub tshav kub ntawm lub compressor lub tso cua sov-melt Frost, kub-melt te ntawm lub tub yees yuav tsum tau nqa tawm nyob rau hauv lub khiav hauj lwm tej yam kev mob ntawm lub tub yees system. Nws zoo nkaus li tias txawm siv txoj kev defrosting twg, nws yuav cuam tshuam qhov kub ntawm qhov txias cia, tshwj xeeb tshaj yog cov tub yees kub melting Frost. Vim tias nws yuav tsum tau muab faib ua cov tsev khaws khoom, uas yog, qee lub tsev khaws khoom tsis txias, thaum lwm qhov ntawm lub tsev khaws khoom yog defrosted. Lub sijhawm defrosting yog ntev dua, thiab qhov cuam tshuam ntawm qhov chaw cia kub kuj tseem ntau dua. Yog tias qhov chaw cia khoom kub hloov pauv ntau dhau, nws yuav cuam tshuam rau qhov zoo ntawm cov zaub mov hauv qhov chaw cia, tshwj xeeb tshaj yog cov khoom noj tshiab. Lub melted Frost yuav tsum tau ntxuav nyob rau hauv lub sij hawm, txwv tsis pub nws yuav ua rau khov ntawm lub warehouse pem teb.
