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 izikimu ezininzi zokutshabalalisa igesi eshushu, isenzo sesiqhelo kukuthumela igesi ephezulu yoxinzelelo kunye nobushushu obuphezulu obukhutshwa kwicompressor ukuya kwi-evaporator ukukhulula ubushushu kunye nokuqhaqha, ukuze ulwelo olujikisiweyo lungene komnye umphunga ukuze lufunxe. ubushushu kwaye bube ngumphunga bube bubushushu obuphantsi kunye negesi yoxinzelelo oluphantsi, kwaye emva koko ubuyela kwizibuko lokufunxa icompressor ukugqiba umjikelo.
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 into yokhuseleko iphantsi.
I-4, i-mechanical defrosting eyenziweyo
Umbhobho wogcino olubandayo oluncinci lokunyibilikisa umbhobho wokugcina obandayo wokuphelisa isikhenkce ngesandla kunoqoqosho, eyona ndlela yoqobo yokuqhaqha. Ukugcinwa okubandayo okukhulu kunye nokuchithwa kwe-artificial ayiyonyani, ukusebenza kwentloko kunzima, ukusetyenziswa komzimba kukhawuleza kakhulu, ixesha lokugcinwa kwindawo yokugcina impahla lide kakhulu liyingozi empilweni, ukuchithwa kweqhwa akulula ukugqiba, kunokubangela ukuguquka kwe-evaporator, kwaye isenokwaphula umphunga kwaye ikhokelele kwiingozi zokuvuza ezikhenkcezayo.
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-aluminium ayifanelekanga ukusetyenziswa kwe-defrosting elula kunye nerhabaxa eyenziwe ngomatshini njengentsimbi, ngoko ke indlela yokucima i-aluminium ityhubhu kufuneka ikhethe ukutshitshiswa kwentambo yombane kunye ne-fluorine eshushu indlela yokuqhawula, idityaniswe nokusetyenziswa kwamandla, umlinganiselo wokwanelisa amandla. kunye nokhuseleko kunye nezinye izinto, i-aluminiyam i-tube defrosting ifaneleke ngakumbi ukukhetha indlela yokucima i-fluorine eshushu.
Ukusetyenziswa kwe-fluoride eshushu yokuqhaqha
Isixhobo sokuguqula isalathiso se-freon esiphuhliswe ngokomgaqo wokutshitshiswa kwerhasi eshushu, okanye inkqubo yokuguqula eyenziwe ngamaqela eevalvu ze-electromagnetic (iivalvu zesandla) eziqhagamshelwe, oko kukuthi, isikhululo sokulawula ifriji, inokuqonda ukusetyenziswa kwefluorine eshushu 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. Njenge: isixhobo sokuguqula isitshixo esinye 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.
okukhethekileyo
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.
