Vim tias cov dej khov ntawm cov evaporator nyob rau hauv qhov chaw txias, nws tiv thaiv kev ua haujlwm thiab kev nthuav tawm ntawm lub peev xwm txias ntawm lub tub yees evaporator (pipeline), thiab thaum kawg cuam tshuam rau lub tub yees. Thaum lub thickness ntawm cov Frost txheej (ice) nyob rau saum npoo ntawm lub evaporator mus txog ib tug npaum li cas, lub tub yees efficiency txawm poob mus rau tsawg tshaj li 30%, uas ua rau ib tug loj pov tseg ntawm hluav taws xob lub zog thiab shortening lub neej kev pab cuam ntawm lub tub yees system. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua kom txias cia defrost ua haujlwm hauv lub voj voog tsim nyog.
Defrosting lub hom phiaj
1, txhim kho lub tub yees efficiency ntawm lub system;
2. Ua kom zoo ntawm cov khoom khov hauv lub tsev rau khoom
3, txuag zog;
4, ncua kev pab cuam lub neej ntawm txias cia system.
Txoj kev Defrosting
Txias cia defrosting txoj kev: roj kub defrosting (kub fluorine defrosting, kub ammonia defrosting), dej defrosting, hluav taws xob defrosting, mechanical (artificial) defrosting, thiab lwm yam.
1, kub gas defrost
Haum rau qhov loj, nruab nrab thiab me me txias cia yeeb nkab defrosting ncaj qha kub kub gaseous condensate rau hauv lub evaporator tsis nres qhov ntws, evaporator kub nce, thiab Frost txheej thiab txias paug sib koom ua ke los yog ces tev tawm. Cov roj kub defrosting yog kev lag luam thiab txhim khu kev qha, yooj yim rau kev txij nkawm thiab kev tswj hwm, thiab nws cov peev txheej thiab kev tsim kho nyuaj tsis loj. Txawm li cas los xij, kuj tseem muaj ntau cov roj cua kub defrosting schemes, qhov kev xyaum ib txwm yog xa cov roj kub siab thiab kub kub tawm los ntawm compressor mus rau hauv evaporator kom tso cua sov thiab defrosting, kom cov kua condensed ces nkag mus rau lwm evaporator kom nqus tau. cua sov thiab evaporate rau hauv qhov kub thiab txias tsis tshua muaj roj, thiab tom qab ntawd rov qab mus rau qhov chaw nres nkoj compressor kom tiav ib lub voj voog.
2, dej tshuaj tsuag defrost
Nws yog dav siv rau defrosting ntawm loj thiab nruab nrab chillers
Periodically txau cov evaporator nrog chav dej kub kom yaj lub Frost txheej. Txawm hais tias cov nyhuv defrosting zoo heev, nws yog qhov tsim nyog rau cov cua txias dua, thiab nws nyuaj rau kev khiav lag luam rau evaporation coils. Nws kuj tseem tuaj yeem txau cov evaporator nrog kev daws nrog qhov kub thiab txias dua, xws li 5% -8% concentrated brine, txhawm rau tiv thaiv kev tsim cov te.
3. Fais defrosting
Hluav taws xob cua sov yeeb nkab defrosting feem ntau yog siv nyob rau hauv nruab nrab thiab me me cua txias; Hluav taws xob cua sov hlau defrosting feem ntau yog siv nyob rau hauv nruab nrab thiab me me txias cia txhuas raj
Hluav taws xob cua sov defrosting, rau lub chiller yog yooj yim thiab siv tau yooj yim; Txawm li cas los xij, rau cov ntaub ntawv ntawm aluminium tube txias cia, qhov teeb meem ntawm kev tsim kho ntawm aluminium fin installation ntawm hluav taws xob cua sov hlau tsis yog me me, thiab qhov tsis ua hauj lwm tus nqi kuj tseem nyob rau yav tom ntej, kev saib xyuas thiab kev tswj xyuas nyuaj, kev lag luam tsis zoo, thiab qhov kev nyab xeeb yog qhov tsawg.
4, mechanical dag defrosting
Me me txias cia yeeb nkab defrosting rau txias cia yeeb nkab phau ntawv defrosting yog ntau yig, feem ntau thawj defrosting txoj kev. Kev cia txias loj nrog cov khoom siv dag zog yog qhov tsis muaj tseeb, lub taub hau ua haujlwm yog qhov nyuaj, kev siv lub cev nrawm dhau, lub sijhawm khaws cia hauv lub tsev khaws khoom ntev dhau los ua rau muaj kev phom sij rau kev noj qab haus huv, defrosting tsis yooj yim ua kom tiav, yuav ua rau lub evaporator deformation, thiab tej zaum yuav ua rau lub evaporator tawg thiab ua rau cov tub yees xau teeb meem.
Kev xaiv hom (Fluorine system)
Raws li qhov sib txawv ntawm cov evaporator ntawm qhov txias cia, qhov tsim nyog defrosting txoj kev raug xaiv, thiab kev siv lub zog, kev siv kev nyab xeeb, kev teeb tsa thiab kev ua haujlwm nyuaj yog raug tshuaj xyuas ntxiv.
1, txoj kev defrosting ntawm lub kiv cua txias
Muaj cov raj hluav taws xob defrosting thiab dej defrosting tuaj yeem xaiv. Cov cheeb tsam uas siv dej yooj yim dua tuaj yeem nyiam cov dej ntws tawm dej txias chiller, thiab cov cheeb tsam uas muaj dej tsis txaus nyiam xaiv hluav taws xob cua sov yeeb nkab Frost chiller. Dej yaug Frost chiller feem ntau teeb tsa hauv cov cua txias loj, tub yees system.
2. Defrosting txoj kev ntawm steel kab
Muaj cov fluorine kub defrosting thiab khoom siv dag zog defrosting xaiv.
3. Defrosting txoj kev ntawm txhuas raj
Muaj cov thermal fluoride defrosting thiab hluav taws xob thermal defrosting xaiv. Nrog rau kev siv ntau ntawm txhuas raj evaporator, lub defrosting ntawm txhuas raj tau them ntau thiab ntau xim los ntawm cov neeg siv. Vim yog cov khoom siv vim li cas, txhuas raj yog qhov yooj yim tsis haum rau kev siv yooj yim thiab ntxhib dag dag dag zoo li hlau, yog li cov txheej txheem defrosting ntawm txhuas raj yuav tsum xaiv hluav taws xob xaim defrosting thiab kub fluorine defrosting txoj kev, ua ke nrog kev siv hluav taws xob, kev siv hluav taws xob. thiab kev nyab xeeb thiab lwm yam, aluminium tube defrosting yog tsim nyog los xaiv cov fluorine kub defrosting txoj kev.
Hot fluoride defrosting daim ntawv thov
Lub freon flow direction conversion khoom tsim raws li lub hauv paus ntsiab lus ntawm cov roj kub defrosting, los yog ib tug conversion system muaj li ntawm ib tug xov tooj ntawm electromagnetic li qub (tes li qub) kev cob cog rua, uas yog, ib tug refrigerant regulating chaw nres tsheb, muaj peev xwm paub txog daim ntawv thov ntawm kub fluorine defrosting nyob rau hauv txias cia.
1, phau ntawv hloov chaw nres tsheb
Nws yog dav siv hauv cov tub yees loj xws li kev sib txuas ua ke.
2, kub fluorine hloov khoom siv
Nws yog dav siv nyob rau hauv me me thiab nruab nrab-qhov loj me ib lub tub yees system. Xws li: ib qho tseem ceeb kub fluorine defrosting hloov dua siab tshiab ntaus ntawv.
Ib nias kub fluorine defrosting
Nws yog qhov tsim nyog rau kev ua haujlwm ywj pheej ntawm ib qho compressor (tsis haum rau kev sib txuas ntawm kev sib txuas, multistage thiab overlapping units). Nws yog siv rau hauv me me thiab nruab nrab-qhov txias cia yeeb nkab defrosting thiab dej khov kev lag luam defrosting.
peculiarity
1, phau ntawv tswj, ib-nias conversion.
2, cua sov los ntawm sab hauv, Frost txheej thiab cov yeeb nkab phab ntsa tuaj yeem yaj thiab poob, lub zog efficiency piv 1: 2.5.
3, defrosting kom huv si, ntau tshaj 80% ntawm Frost txheej yog ib qho khoom poob.
4, raws li daim duab kos ncaj qha rau ntawm chav tsev condensing, tsis xav tau lwm yam khoom siv tshwj xeeb.
5, raws li qhov sib txawv ntawm qhov kub thiab txias, feem ntau nws yuav siv li 30 mus rau 150 feeb.
