Ngaba uyayazi indlela yokunyibilikisa eli gumbi libandayo-Defrost Heating Tube?

A. Isishwankathelo

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. 

B. Injongo yokuqhaqha

1, ukuphucula ukusebenza kakuhle kwefriji yenkqubo;

2. Qinisekisa umgangatho weemveliso ezikhenkcezisiweyo kwindawo yokugcina impahla;

3, gcina amandla;

4, ukwandisa ubomi benkonzo yenkqubo yokugcina ebandayo.

C. iindlela zokuqhaqha

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 wokuthomalalisa:

I-condensate ye-gaseous eshushu yobushushu obuphezulu ifakwe ngokuthe ngqo kwi-evaporator ngaphandle kokuphazamiseka, kwaye ubushushu be-evaporator buphakama, nto leyo ebangela ukuba i-frost layer kunye ne-cold discharge joint inyibilike okanye emva koko ikhuphe. Ukutshatyalaliswa kwegesi eshushu kunoqoqosho kwaye kunokwethenjelwa, kukulungele ukugcinwa nokulawulwa, kwaye utyalo-mali kunye nobunzima bokwakha abukho bukhulu.

2, ukunyibilika kwesitshizi samanzi

Isetyenziswa kakhulu ekuthotyweni kwe-chiller enkulu kunye nephakathi:

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% ukuya kwi-8% ye-concentrated brine, ukukhusela ukuvela kweqabaka.

I-3, i-defrost yombane

Umbhobho wobushushu wombane usetyenziswa kakhulu kwizikhewu eziphakathi nezincinci:

Intambo yokufudumeza yombane isetyenziselwa ukutshitshiswa kwe-aluminium yomqolo ityhubhu yokufudumeza kombane kwindawo ephakathi kunye nencinci yokugcina ebandayo, elula kwaye kulula ukuyisebenzisa kwi-chiller; 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 omncinci wogcino olubandayo lokunyibilikisa isicelo:

Umbhobho wogcino olubandayo owenziwe ngesandla uwonga ngakumbi, indlela yokuthomalalisa yoqobo. Ukugcinwa okubandayo okukhulu kunye ne-defrosting eyenziweyo ayisiyonyani, ukusebenza kwentloko kunzima, ukusetyenziswa komzimba kukhawuleza kakhulu, ixesha lokugcinwa kwindawo yokugcina lide kakhulu kwaye liyingozi empilweni, ukuchithwa kwe-frosting akulula ukuba kucokiseke, kunokubangela ukuba i-evaporator. deformation, kwaye isenokwaphula umphunga okhokelela kwiingozi zokuvuza.

D. inkqubo yefluorine ukhetho lwendlela yokuphelisa isikhenkce

Ngokutsho kwe-evaporator eyahlukileyo yokugcina ebandayo, khetha indlela efanelekileyo yokunciphisa i-frosting. Inani elincinci leevenkile ezincinci ezibandayo zisebenzisa ucango oluvaliweyo ukunyibilikisa ngokwendalo kusetyenziswa ubushushu bomoya. Abanye abapholisi bethala leencwadi lobushushu obuphezulu bakhetha ukumisa isikhenkcezisi, bavule i-fan yokupholisa ngokwahlukeneyo, basebenzise ifeni ukujikelezisa umoya ukunyibilikisa, kwaye musa ukwenza umbhobho wobushushu wombane ufezekise injongo yokonga amandla.

1, indlela yokuphelisa isikhenkce kwindawo epholileyo:

(1) Kukho ukuchithwa kwetyhubhu yombane kunye ne-defrosting yamanzi inokukhethwa, iindawo ezinamanzi afanelekileyo zinokukhetha ukukhetha i-water defrosting chiller, iindawo zokunqongophala kwamanzi zikhetha ukukhetha i-chiller yombane yombane.

(2) ukuthotywa kwetyhubhu yombane kusetyenziswa kakhulu kwi-cooler defrosting encinci yomoya; Ukugungxulwa kwamanzi kwi-frost chiller ngokubanzi kulungiselelwe kwisimo somoya esikhulu, inkqubo yefriji.

2. Indlela yokunyibilikisa yomqolo wentsimbi:

Kukho i-fluorine eshushu yokususa iqhwa kunye nokukhethwa kwe-artificial defrosting.

3. Indlela yokucima i-aluminiyam ityhubhu:

Kukho i-thermal fluoride defrosting kunye ne-electric thermal defrosting options.

E. yokugcina ebandayo defrosting ixesha

Ngoku uninzi lwendawo ebandayo yokugcina i-defrosting ilawulwa ngokuhambelana neprobe yeqondo lokushisa okanye i-defrosting ixesha. Isantya sokuqhaqha, ixesha, kunye nobushushu bokumisa ubushushu kufuneka buhlengahlengiswe ngokobungakanani kunye nomgangatho weempahla ezipakishweyo.

Ekupheleni kwexesha lokuqhaqha, kwaye emva koko ukuya kwixesha le-drip, i-fan iqala. Qaphela ukuba ungabeki ixesha lokuqhaqhazela ixesha elide kwaye uzame ukufezekisa ukutshatyalaliswa okufanelekileyo. (Umjikelo wokuphelisa iqhwa usekelwe ngokubanzi kwixesha lonikezelo lwamandla okanye ixesha lokuqalisa icompressor.)

F. Uhlalutyo lwezizathu zeqabaka egqithisileyo

Kukho izizathu ezininzi ezichaphazela ukubunjwa kweqabaka, njenge: isakhiwo se-evaporator, indawo ye-atmospheric (ubushushu, ukufuma) kunye nesantya sokuhamba komoya. Iimpembelelo ekwenziweni kweqabaka kunye nokusebenza kokupholisa umoya zezi zilandelayo:

1, umahluko weqondo lobushushu phakathi kwe-inlet yomoya kunye nefeni yokugcina ebandayo;

2, ukufuma komoya otsalweyo;

3, izithuba zamaphiko;

4, izinga lokungena komoya.

Xa ubushushu bogcino bungaphezulu kwe-8℃, inkqubo yogcino ebandayo eqhelekileyo iphantse ingabi yiqabaka; Xa amaqondo obushushu akwi-Ambient yi-5℃ ~ 3℃ kwaye ukufuma komoya kukhulu, i-air cooler kulula ukuyiqaba; Xa ubushushu be-ambient buhla, isantya sokubunjwa kweqabaka siyancipha ngenxa yokuba umthamo womswakama emoyeni uyancipha.
