Uyazi ukuthi ungawancibilikisa kanjani lawa magumbi abandayo – i-Defrost Heating Tube?

A. Ukubuka Konke

Ngenxa yeqhwa elisebusweni be-evaporator endaweni yokugcina ebandayo, livimbela ukuqhutshwa kanye nokusabalala kwamandla okubanda e-evaporator yokuqandisa (ipayipi), futhi ekugcineni kuthinta umphumela wokuqandisa. Lapho ubukhulu bengqimba yeqhwa (iqhwa) ebusweni be-evaporator bufinyelela ezingeni elithile, ukusebenza kahle kweqhwa kwehla ngisho nangaphansi kuka-30%, okuholela ekuchithekeni okukhulu kwamandla kagesi futhi kunciphise impilo yesevisi yesistimu yokuqandisa. Ngakho-ke, kubalulekile ukwenza umsebenzi wokuncibilikisa iqhwa endaweni yokugcina ebandayo emjikelezweni ofanele. 

B. Inhloso yokuncibilikisa iqhwa

1, ukuthuthukisa ukusebenza kahle kwesistimu yokubanda;

2. Qinisekisa ikhwalithi yemikhiqizo eqandisiwe endaweni yokugcina impahla;

3, londoloza amandla;

4, yandisa impilo yesevisi yesistimu yokugcina ebandayo.

C. izindlela zokuncibilikisa iqhwa

Izindlela zokuncibilikisa iqhwa endaweni ebandayo: ukuncibilikisa igesi eshisayo (ukuncibilikisa i-fluorine eshisayo, ukuncibilikisa i-ammonia eshisayo), ukuncibilikisa amanzi, ukuncibilikisa ugesi, ukuncibilikisa ngomshini (okwenziwayo), njll.

1, ukuncibilikisa igesi eshisayo

Ifanelekela ukuncibilikisa ipayipi lokugcina iqhwa elikhulu, eliphakathi nelincane:

I-condensate yegesi eshisayo enokushisa okuphezulu ifakwa ngqo ku-evaporator ngaphandle kokungenelela, futhi izinga lokushisa le-evaporator liyakhuphuka, okubangela ukuthi ungqimba lwesithwathwa kanye ne-cold discharge joint kuncibilike noma kuphume. Ukuncibilikisa igesi eshisayo kuyonga futhi kuthembekile, kulula ukugcinwa nokuphathwa, futhi ubunzima bayo bokutshalwa kwezimali kanye nokwakha abukhulu.

2, ncibilikisa iqhwa ngesifutho samanzi

Isetshenziswa kabanzi ekuncibilikiseni i-chiller enkulu nephakathi nendawo:

Futha i-evaporator ngezikhathi ezithile ngamanzi okushisa kwegumbi ukuze uncibilikise ungqimba lwesithwathwa. Nakuba umphumela wokuncibilikisa umuhle kakhulu, ufaneleka kakhulu kuma-air cooler, futhi kunzima ukuwasebenzisa kuma-evaporation coils. Kungenzeka futhi ukufutha i-evaporator ngesisombululo esinokushisa okuphezulu kokuqandisa, njenge-5% kuya ku-8% yamanzi acwebile, ukuvimbela ukwakheka kwesithwathwa.

3, ukuncibilikisa ugesi

Ipayipi lokushisa likagesi lisetshenziswa kakhulu kuma-cooler aphakathi naphakathi namancane:

Intambo yokushisa kagesi isetshenziselwa kakhulu ukuncibilikisa i-aluminium row tube ukushisa ngogesi endaweni yokugcina ebandayo ephakathi nendawo encane, okulula ukuyisebenzisa efrijini; Kodwa-ke, esimweni sokugcina ebanda nge-aluminium tube, ubunzima bokwakhiwa kokufakwa kwe-aluminium fin yentambo yokushisa kagesi abuncane, futhi izinga lokwehluleka liphezulu esikhathini esizayo, ukulungiswa nokuphathwa kunzima, umnotho mubi, kanti nesici sokuphepha siphansi kakhulu.

4, ukuncibilikisa okwenziwe ngomshini

Isicelo sokuncibilikisa ipayipi lokugcina iqhwa elincane:

Ukuncibilikisa ipayipi lokugcina imfucuza ngesandla kuyonga kakhulu, indlela yokuqala yokuncibilikisa imfucuza. Indawo yokugcina imfucuza enkulu enokuncibilikisa okwenziwayo ayisebenzi, ukusebenza kwekhanda kunzima, ukusetshenziswa ngokomzimba kuyashesha kakhulu, isikhathi sokugcina imfucuza endlini yokugcina impahla side kakhulu futhi siyingozi empilweni, ukuncibilikisa imfucuza akulula ukukwenziwa ngokuphelele, kungabangela ukuguquka kwe-evaporator, futhi kungaphula ngisho ne-evaporator okuholela ezingozini zokuvuza.

D. Ukukhetha indlela yokuncibilikisa uhlelo lwe-fluorine

Ngokusho kwe-evaporator ehlukene yesitoreji esibandayo, khetha indlela yokuncibilikisa efanelekile. Inani elincane lezitolo ezincane ezibandayo zisebenzisa umnyango wokuvala ukuze zincibilikise ngokwemvelo zisebenzisa ukushisa komoya. Ezinye iziqandisi zomtapo wolwazi okushisa okuphezulu zikhetha ukumisa isiqandisi, zivule ifeni yesiqandisi ngokwehlukana, zisebenzise ifeni ukuhambisa umoya ukuze uncibilikise, futhi azivumeli ipayipi lokushisa likagesi ukuthi lifeze injongo yokonga amandla.

1, indlela yokuncibilikisa iqhwa ye-cooler:

(1) Kukhona ukuncibilikisa amashubhu kagesi kanye nokuncibilikisa amanzi kungakhethwa, izindawo ezinamanzi alula kakhulu zingakhetha ukukhetha i-chiller yokuncibilikisa amanzi, izindawo zokuntuleka kwamanzi zikhetha ukukhetha i-chiller yokuncibilikisa amashubhu kagesi.

(2) ukuncibilikisa ishubhu kagesi kusetshenziswa kakhulu ekuncibilikiseni umoya omncane opholile; Isiqandisi seqhwa esihlanza amanzi ngokuvamile silungiselelwe ohlelweni olukhulu lokupholisa umoya kanye nelokuqandisa.

2. Indlela yokuncibilikisa ungqimba lwensimbi:

Kunezinketho zokuncibilikisa i-fluorine eshisayo kanye nezinketho zokuncibilikisa okwenziwe.

3. Indlela yokuncibilikisa i-aluminium tube:

Kunezinketho zokuncibilikisa i-fluoride eshisayo kanye nezinketho zokuncibilikisa i-fluoride eshisayo kagesi.

Isikhathi sokuncibilikisa iqhwa endaweni ebandayo

Manje iningi lokuncibilikisa iqhwa endaweni ebandayo lilawulwa ngokweprobe yokushisa yokuncibilikisa noma isikhathi sokuncibilikisa. Imvamisa yokuncibilikisa, isikhathi, kanye nokushisa kokumisa ukuncibilikisa kufanele kulungiswe ngokwenani kanye nekhwalithi yezimpahla ezihlanganisiwe.

Ekupheleni kwesikhathi sokuncibilikisa, bese kuba yisikhathi sokuconsa, ifeni iyaqala. Qaphela ukuthi ungabeki isikhathi sokuncibilikisa isikhathi eside kakhulu bese uzama ukufeza ukuncibilikisa okufanele. (Umjikelezo wokuncibilikisa ngokuvamile usekelwe esikhathini sokunikezwa kwamandla noma isikhathi sokuqala kwe-compressor.)

F. Ukuhlaziywa kwezimbangela zeqhwa eliningi

Kunezizathu eziningi ezithinta ukwakheka kweqhwa, njenge: isakhiwo se-evaporator, indawo enomoya (izinga lokushisa, umswakama) kanye nesivinini sokugeleza komoya. Imiphumela ekwakhekeni kweqhwa kanye nokusebenza kokupholisa umoya yilena elandelayo:

1, umehluko wokushisa phakathi komoya wokungena kanye nefeni yokugcina ebandayo;

2, umswakama womoya ophefumulwayo;

3, isikhala phakathi kwamaphiko;

4, izinga lokugeleza komoya okungena.

Uma izinga lokushisa lokugcina liphakeme kuno-8℃, uhlelo lokugcina olujwayelekile lokubanda cishe aluqandisi; Uma izinga lokushisa lokushisa liyi--5℃ ~ 3℃ futhi umswakama womoya umkhulu, i-air cooler kulula ukuyiqandisa; Uma izinga lokushisa lokushisa liphansi, ijubane lokwakheka kweqhwa liyancipha ngoba okuqukethwe umswakama emoyeni kuyancipha.
