Iifriji yomisa umoyasisixhobo esomisa umoya esicinezelekileyo esisebenzisa imigaqo yomzimba ukukhenkceza ukufuma kumoya ocinezelweyo ongaphantsi kwendawo yombethe, ukujiya kumanzi alulwelo asuka kumoya ocinezelweyo kwaye uwakhuphe. Ilinganiselwe kwindawo yokukhenkceza yamanzi, ngokwethiyori iqondo lobushushu bombethe lingasondele kwi-0 degrees. Ngokwesiqhelo, iqondo lombethe lobushushu bomkhenkce olungileyo linokufikelela kwi-10 degrees.
Ngokomahluko phakathi kwabatshintshi bobushushu beifriji zokomisa umoya, okwangoku kukho iindidi ezimbini zezomisi zomoya ezine-tube-fin zokutshintshiselana kobushushu kunye ne-plate-type exchange exchangers (ekubhekiselwa kuyo njengotshintshiselwano lweepleyiti) kwimarike. Ngenxa yetekhnoloji evuthiweyo, ubume be-compact, ukusebenza kakuhle kwe-thermal, kwaye akukho ngcoliseko lwesibini, isomisi somoya esifudumezayo sibe yeyona nto iphambili kwimarike yokomisa umoya. Nangona kunjalo, zininzi izinto ezingalunganga kuyilo kunye nokusetyenziswa kwe-tube-fin yokutshintshiselana kobushushu. Owona msebenzi uphambili kule miba ilandelayo:
1. Umthamo omkhulu:
I-tube-fin exchanger heat exchanger ngokuqhelekileyo inesakhiwo se-cylindrical esithe tye. Ukuze ulungelelanise ukuma komtshini wokushisa, yonke idizayini yomshini wokuqandisa kunye nowomisa unokulandela kuphela umatshini wokushisa ukushisa. Ngoko ke, umatshini wonke mkhulu, kodwa indawo yangaphakathi ayinanto. , Ngokukodwa kwisixhobo esiphakathi kunye nesikhulu, i-2/3 yendawo ngaphakathi kumatshini wonke i-surplus, ngaloo ndlela ibangela inkunkuma yendawo engadingekile.
2. Ulwakhiwo olunye:
I-tube-fin heat exchanger ngokubanzi ithatha i-design-one-one, oko kukuthi, i-processing processing capacity ehambelana nesomisi somoya ihambelana nomgangatho ohambelanayo wokutshintshiselana kobushushu, obangela ukulinganiselwa kwinkqubo yokuvelisa kwaye ayikwazi ukusetyenziswa ngokuguquguqukayo ngokudibeneyo. Iindlela zokusebenzisa umtshintshi wobushushu ofanayo ukwenza i-dryer zomoya kunye namandla ahlukeneyo okusebenza, okuya kukhokelela ngokuqinisekileyo ekwandeni kwe-inventory yezinto eziluhlaza.
3. Umyinge wokutshintshiselana kobushushu
Ukusebenza kokufudumeza ubushushu be-tube-fin exchanger heat exchanger ngokuqhelekileyo malunga ne-85%, ngoko kuyimfuneko ukufezekisa umphumo ofanelekileyo wokudlulisa ubushushu.Uyilo lwenkqubo yonke yefriji kufuneka lunyuke ngaphezu kwe-15% kwisiseko sokubala okufunekayo. amandla efriji, ngaloo ndlela ukwandisa iindleko zenkqubo kunye nokusetyenziswa kwamandla.
4. Amaqamza omoya kwi-tube-fin exchanger ubushushu
Ulwakhiwo lwe-square fin kunye neqokobhe elijikelezayo le-tube-fin exchanger heat exchanger lishiya indawo yokutshintshiselana engeyiyo-ubushushu kumjelo ngamnye, ibangela ukubhubhudla komoya. I-baffles ye-evaporator ivumela omnye womoya ocinezelweyo ukuba ubaleke ngaphandle kokutshintshana kobushushu. Oku kunciphisa indawo yombethe yegesi yemveliso, kwaye ukwandisa umthamo wokupholisa akusombululi ngokupheleleyo ingxaki. Ke ngoko, iqondo lombethe loxinzelelo lwe-tube-fin freeze dryer ngokubanzi lingaphezulu kwe-10°C, elingenako ukufikelela kweyona 2°C ilungileyo.
5. Ukunganyangeki komhlwa
I-tube-fin yokutshintshiselana kobushushu iqhele ukwenziwa ngeetyhubhu zobhedu kunye namaphiko e-aluminiyam, kwaye indawo ekujoliswe kuyo yirhasi eqhelekileyo ecinezelweyo kunye nerhasi engadlekiyo. Xa zisetyenziswa kwizihlandlo ezithile ezikhethekileyo, ezifana nezomisi efrijini zaselwandle, ukupholisa igesi ekhethekileyo kunye nokomisa Oomatshini, njl.njl., bathanda ukuhlwa, nto leyo eyenza bufutshane kakhulu ubomi benkonzo, okanye ayinakusetyenziswa kwaphela.
Ngokujonga iimpawu ze-tube-fin ezichazwe ngasentla, i-plate heat exchanger inokwenza ezi ntsilelo. Inkcazo ethile yile ilandelayo:
1. Ubume obuqinileyo kunye nobukhulu obuncinci
I-plate heat exchanger inesakhiwo sesikwere kwaye ithatha indawo encinci. Inokuthi idibaniswe ngokuguquguqukayo kunye namacandelo efriji kwisixhobo ngaphandle kokuchithwa kwendawo.
2. Imodeli iyaguquguquka kwaye iyatshintsha
Umtshintshi wobushushu wepleyiti unokudityaniswa ngendlela eyimodyuli, oko kukuthi, inokudityaniswa ibe ngumthamo ofunekayo wokuqhuba ngendlela ye-1+1=2, eyenza uyilo lomatshini wonke ubhetyebhetye kwaye utshintshe, kwaye unokulawula ngempumelelo ngakumbi. uluhlu lwempahla ekrwada.
3. Ukusebenza kakuhle kokutshintsha kobushushu
Umjelo wokuhamba we-plate exchanger heat exchanger encinci, i-plate fins i-waveforms, kwaye utshintsho olunqamlezayo lunzima. Ipleyiti encinci inokufumana indawo enkulu yokutshintshiselana kobushushu, kwaye isikhokelo sokuhamba kunye nesantya sokuhamba kolwelo luhlala lutshintshwa, olunyusa izinga lokuhamba kolwelo. Ukuphazamiseka, ngoko inokufikelela kwi-turbulent flow ngesantya esincinci kakhulu sokuhamba. Kwiqokobhe kunye ne-tube yokutshintshiselana kobushushu, ulwelo olubini luhamba kwicala lombhobho kunye necala leqokobhe ngokulandelelanayo. Ngokubanzi, ukuhamba kukunqumlana, kwaye i-logarithmic iavareji ye-avareji yomahluko wokulungisa i-coefficient incinci. , Kwaye i-plate heat exchangers ininzi i-co-current okanye i-counter-current flow, kwaye i-coefficient yokulungisa idla malunga ne-0.95. Ukongeza, ukuhamba kwamanzi abandayo kunye nobushushu obushushu kwi-plate exchanger heat exchanger ihambelana nendawo yokutshintshiselana kobushushu ngaphandle kokuhamba kwe-bypass, okwenza i-plate heat exchanger Umahluko weqondo lokushisa ekupheleni kobushushu buncinci, obunokuba ngaphantsi kwe-1. °C. Ke ngoko, indawo yoxinzelelo lombethe yesomisi esikhenkcezisi kusetyenziswa isitshintshisi sobushushu sepleyiti inokuba ngaphantsi njenge-2°C.
4. Akukho i-angle efileyo yokutshintshwa kobushushu, ngokusisiseko ukuphumeza i-100% yokutshintsha kobushushu
Ngenxa yendlela yaso ekhethekileyo, isitshintshi sobushushu sepleyiti senza indawo yokutshintshiselana ngobushushu idibane ngokupheleleyo nomphezulu wepleyiti ngaphandle kokutshintshiselana ngobushushu ii-engile ezifileyo, akukho mingxunya yokukhupha amanzi, kwaye akukho kuvuza komoya. Ngoko ke, umoya ocinezelweyo unokufezekisa i-100% yokutshintsha kobushushu. Qinisekisa ukuzinza kwendawo yombethe yemveliso egqityiweyo.
5. Ukumelana nokugqwesa okulungileyo
Isitshintshi sobushushu sepleyiti senziwe nge-aluminium alloy okanye isakhiwo sensimbi engenasici, esinokumelana ne-corrosion elungileyo kwaye sinokuphepha ungcoliseko lwesibini lomoya ocinezelweyo. Ke ngoko, inokulungelelaniswa kwiziganeko ezahlukeneyo ezikhethekileyo, kubandakanywa iinqanawa zaselwandle, ezinegesi ezonakalisayo Ishishini lemichiza, kunye nokutya okungqongqo ngakumbi kunye namashishini amayeza.
Ukudibanisa iimpawu ezingentla apha, i-plate heat exchanger ineenzuzo ezingenakunqandwa zetyhubhu kunye ne-fin heat exchanger. Xa kuthelekiswa netyhubhu kunye ne-fin exchanger heat exchanger, i-plate exchanger heat exchanger inokugcina i-30% phantsi komthamo ofanayo wokucubungula. Ngoko ke, ukucwangciswa kwenkqubo yefriji yomshini wonke kunokuncitshiswa ngama-30%, kwaye ukusetyenziswa kwamandla kunokunciphisa ngaphezu kwe-30%. Umthamo womatshini wonke unokuncitshiswa ngaphezu kwe-30%.
Ipleyiti yoguqulo yamva nje-tshintsha isiboniso sesomisi somoya esisefrijini
