Ngenxa yeqabaka ebusweni be-evaporator kwindawo yokugcina ebandayo, ikhusela ukuqhuba kunye nokusabalalisa amandla abandayo e-evaporator yefriji (ipayipi), kwaye ekugqibeleni ichaphazela umphumo wefriji. Xa ubukhulu bomgangatho weqabaka (umkhenkce) kumphezulu we-evaporator bufikelela kwinqanaba elithile, ukusebenza kakuhle kwefriji kuyancipha ukuya ngaphantsi kwe-30%, kubangele inkunkuma enkulu yamandla ombane kunye nokunciphisa ubomi benkonzo yenkqubo yefriji. Ngoko ke, kuyimfuneko ukwenza ukugcinwa okubandayo kwe-defrost operation kumjikelo ofanelekileyo.
Ukuphelisa injongo
1, ukuphucula ukusebenza kakuhle kwefriji yenkqubo;
2. Qinisekisa umgangatho weemveliso ezikhenkcezisiweyo kwindawo yokugcina impahla
3, gcina amandla;
4, ukwandisa ubomi benkonzo yenkqubo yokugcina ebandayo.
Indlela yokuqhaqha
Iindlela ezibandayo zokuphelisa i-frosting: igesi eshushu (i-hot fluorine defrosting, i-ammonia eshushu, i-ammonia eshushu), i-water frosting, i-frosting yombane, i-mechanical (artificial) i-defrosting, njl.
1, ukunyibilika kwerhasi eshushu
Ifanele umbhobho wokugcina obandayo omkhulu, ophakathi kunye omncinci oqhaqhazela ngokuthe ngqo ubushushu obuphezulu begesi ye-condensate kwi-evaporator ngaphandle kokumisa ukuhamba, ubushushu be-evaporator bukhuphuka, kunye nomgangatho weqabaka kunye nokukhutshwa okubandayo ngokubambisana kunyibilike okanye emva koko kuxoshwe. Ukutshatyalaliswa kwegesi eshushu kunoqoqosho kwaye kunokwethenjelwa, kukulungele ukugcinwa nokulawulwa, kwaye utyalo-mali kunye nobunzima bokwakha abukho bukhulu. Nangona kunjalo, kukho iinkqubo ezininzi zokutshabalalisa igesi eshushu, into eqhelekileyo kukuthumela irhasi yoxinzelelo oluphezulu kunye nobushushu obuphezulu obukhutshwe kwicompressor ukuya kwi-evaporator ukukhulula ubushushu kunye nokuqhaqha, ukuze ulwelo olujikisiweyo lungene kwenye i-evaporator ukuze lufunxe ubushushu kwaye luqhume kwiqondo eliphantsi lobushushu kunye negesi ephantsi yoxinzelelo, kwaye emva koko ibuyele kwi-compressor port egcweleyo.
2, ukunyibilika kwesitshizi samanzi
Isetyenziswa kakhulu ukunyibilikisa izikhenkce ezinkulu neziphakathi
Ngamaxesha athile fafaza i-evaporator ngamanzi obushushu begumbi ukunyibilikisa umaleko weqabaka. Nangona i-defrosting effect ilungile kakhulu, ifaneleke ngakumbi kwii-coolers zomoya, kwaye kunzima ukusebenzela iikhoyili zokuphefumula. Kwakhona kunokwenzeka ukutshiza i-evaporator ngesisombululo esinobushushu obuphezulu bokukhenkceza, obufana ne-5% -8% ye-concentrated brine, ukukhusela ukubunjwa kweqabaka.
3. Ukutshatyalaliswa kombane
Umbhobho wobushushu bombane wokuthomalalisa ubukhulu becala usetyenziswa kwindawo epholileyo ephakathi kunye nencinci; Iingcingo zokufudumeza zombane zisetyenziswa ikakhulu kwiityhubhu zealuminiyam eziphakathi nezincinci
Ukufudumeza kombane ukutshabalalisa, kuba i-chiller ilula kwaye kulula ukuyisebenzisa; Nangona kunjalo, kwimeko yokugcina i-aluminium ityhubhu ebandayo, ubunzima bokwakhiwa kwe-aluminium fin ukufakwa kocingo lokufudumeza kombane aluncinci, kwaye izinga lokungaphumeleli liphezulu kakhulu kwixesha elizayo, ukugcinwa kunye nokulawula kunzima, uqoqosho luhluphekile, kwaye ukhuseleko luncinci.
I-4, i-mechanical defrosting eyenziweyo
Umbhobho wogcino olubandayo oluncinci lokunyibilikisa umbhobho wokugcina obandayo wokuphelisa isikhenkce ngesandla kunoqoqosho, eyona ndlela yoqobo yokuqhaqha. Ugcino olukhulu olubandayo olunokufakelwa kweqhwa okungeyonyani, ukusebenza kwentloko kunzima, ukusetyenziswa komzimba kukhawuleza kakhulu, ixesha lokugcinwa kwindawo yokugcina impahla lide kakhulu kuyingozi empilweni, ukuphelisa iqhwa akukho lula ukugqiba, kunokubangela uguquko lwe-evaporator, kwaye lusenokwaphula umphunga kwaye lukhokelele kwiingozi zokuvuza kwefriji.
Ukukhetha indlela (inkqubo yeFluorine)
Ngokutsho kwe-evaporator eyahlukileyo yokugcinwa okubandayo, indlela efanelekileyo yokunciphisa ikhethiwe, kunye nokusetyenziswa kwamandla, ukusetyenziswa kwezinto ezikhuselekileyo, ukufakela kunye nobunzima bokusebenza kuphinda kuhlolwe.
1, indlela yokuphelisa i-fan ebandayo
Kukho ukuchithwa kwetyhubhu yombane kunye ne-water defrosting ingakhetha. Iindawo ezinokusetyenziswa kwamanzi ngendlela elunge ngakumbi zinokukhetha ukugungxulwa kwamanzi kwiqabaka, kwaye iindawo ezinqongopheleyo zikholisa ukukhetha umbhobho wobushushu wombane wokupholisa iqabaka. Ukugungxulwa kwamanzi kwi-frost chiller ngokubanzi kulungiselelwe kwisimo somoya esikhulu, inkqubo yefriji.
2. Indlela yokucima umqolo wentsimbi
Kukho i-fluorine eshushu yokususa iqhwa kunye nokukhethwa kwe-artificial defrosting.
3. Indlela yokucima umbhobho we-aluminium
Kukho i-thermal fluoride defrosting kunye ne-electric thermal defrosting options. Ngokusetyenziswa ngokubanzi kwe-aluminium tube evaporator, ukuchithwa kwe-tube ye-aluminium kuye kwahlawulwa ngakumbi nangakumbi ngabasebenzisi. Ngenxa yezizathu eziphathekayo, ityhubhu ye-aluminiyam ayifanelekanga ukusetyenziswa kwe-defrosting elula kunye erhabaxa eyenziwe ngumatshini njengentsimbi, ngoko ke indlela yokucima i-aluminium ityhubhu kufuneka ikhethe ukuchithwa kocingo lombane kunye nendlela yokucima i-fluorine eshushu, idityaniswe nokusetyenziswa kwamandla, umlinganiselo wokusebenza kwamandla kunye nokhuseleko kunye nezinye izinto, i-aluminium tube defrosting defrosting ifaneleke ngakumbi.
Ukusetyenziswa kwe-fluoride eshushu yokuqhaqha
Isixhobo sokuguqula isalathiso se-freon esiphuhliswe ngokomgaqo wokutshitshiswa kwerhasi eshushu, okanye inkqubo yokuguqula eyenziwe ngamaqela eevalve ze-electromagnetic (iivalvu zesandla) eziqhagamshelwe, oko kukuthi, isikhululo sokulawula ifriji, inokuqonda ukusetyenziswa kwefluorine eshushu kwindawo yokugcina ebandayo.
1, isikhululo sohlengahlengiso lwezandla
Isetyenziswa ngokubanzi kwiinkqubo ezinkulu zefriji ezifana noxhumo oluhambelanayo.
2, izixhobo zokuguqula ifluorine eshushu
Isetyenziswa ngokubanzi kwinkqubo yefriji encinci kunye nephakathi. Ezinje: isixhobo sokuguqula isitshixo sefluorine eshushu.
Unqakrazo olunye olushushu lwefluorine defrosting
Ifanelekile kwinkqubo yokujikeleza ezimeleyo ye-compressor eyodwa (engafanelekanga ukufakwa koxhumo lwe-parallel, i-multistage kunye ne-overlapping units). Isetyenziswa kwimibhobho yokugcina ebandayo encinci kunye nobungakanani obuphakathi kunye neshishini lomkhenkce lokuphelisa iqhwa.
into ekhethekileyo
1, ulawulo lwezandla, uguqulelo lokucofa-kanye.
I-2, ukufudumeza ukusuka ngaphakathi, i-frost layer kunye nodonga lombhobho lunokunyibilika kunye nokuwa, umlinganiselo wokusebenza kwamandla 1: 2.5.
I-3, i-defrosting ngokucokisekileyo, ngaphezu kwe-80% ye-frost layer kukuhla okuqinileyo.
I-4, ngokomzobo ofakwe ngokuthe ngqo kwiyunithi yokunciphisa, ayifuni ezinye izixhobo ezikhethekileyo.
5, ngokomahluko wokwenyani kubushushu obuphakathi, kuthatha imizuzu engama-30 ukuya kweli-150.
