Izinga lemveliso yetshiphusi kushishino lwemveliso ye-IC linxulumene kakhulu nobukhulu kunye nenani lamasuntswana omoya abekwe kwitshiphusi. Umbutho olungileyo wokuhamba komoya ungasusa amasuntswana aveliswe ngumthombo wothuli kwigumbi elicocekileyo ukuqinisekisa ukucoceka kwegumbi elicocekileyo, oko kukuthi, umbutho wokuhamba komoya kwigumbi elicocekileyo udlala indima ebalulekileyo kwizinga lemveliso ye-IC. Uyilo lombutho wokuhamba komoya kwigumbi elicocekileyo kufuneka lufezekise ezi njongo zilandelayo: ukunciphisa okanye ukususa umsinga we-eddy kwintsimi yokuhamba komoya ukuze kuthintelwe ukugcinwa kwamasuntswana anobungozi; ukugcina i-gradient yoxinzelelo efanelekileyo ukuthintela ungcoliseko olunqamlezileyo.
Amandla omoya
Ngokomgaqo wegumbi elicocekileyo, amandla asebenza kwiinxalenye aquka amandla obunzima, amandla emolekyuli, ukutsalana phakathi kweenxalenye, amandla okuhamba komoya, njl.
Amandla okuhamba komoya: abhekisa kumandla okuhamba komoya okubangelwa kukuhanjiswa, ukuhamba komoya okubuyayo, ukuhamba komoya obushushu, ukuxukuxa okwenziweyo, kunye neminye imijelo yomoya enesantya esithile sokuhamba ukuze ithwale amasuntswana. Ukuze kulawulwe ngobuchwephesha indawo ecocekileyo yegumbi, amandla okuhamba komoya yeyona nto ibalulekileyo.
Uvavanyo lubonise ukuba kwintshukumo yokuhamba komoya, amasuntswana alandela intshukumo yokuhamba komoya phantse ngesantya esifanayo. Imeko yamasuntswana emoyeni imiselwa kukusasazwa komoya. Ukuhamba komoya okuchaphazela amasuntswana angaphakathi kubandakanya ikakhulu: ukuhamba komoya okuhambisa umoya (kubandakanya ukuhamba komoya ophambili kunye nokuhamba komoya wesibini), ukuhamba komoya kunye nokuhamba komoya obushushu okubangelwa ngabantu abahambahambayo, kunye nokuhamba komoya okubangelwa kukusebenza kwenkqubo kunye nezixhobo zoshishino. Iindlela ezahlukeneyo zokuhambisa umoya, i-interfaces yesantya, abaqhubi kunye nezixhobo zoshishino, kunye neziganeko ezibangelwa kumagumbi acocekileyo zonke zizinto ezichaphazela inqanaba lococeko.
Izinto ezichaphazela umbutho wokuhamba komoya
1. Impembelelo yendlela yokubonelela ngomoya
(1). Isantya sokuhanjiswa komoya
Ukuqinisekisa ukuhamba komoya okufanayo, isantya sokuhambisa umoya kufuneka silingane kwigumbi elicocekileyo elihamba kwicala elinye; indawo efileyo yomphezulu wokuhambisa umoya kufuneka ibe ncinci; kwaye ukwehla koxinzelelo kwi-ULPA kufuneka kufane.
Isantya sokuhambisa umoya esifanayo: oko kukuthi, ukungalingani kokuhamba komoya kulawulwa ngaphakathi kwe-±20%.
Indawo engafi kakhulu kumphezulu womoya: akufuneki nje kuphela ukuba indawo yeplane yesakhelo se-ULPA incitshiswe, kodwa okubaluleke ngakumbi, kufuneka kusetyenziswe i-FFU yemodyuli ukuze kube lula isakhelo esingafunekiyo.
Ukuqinisekisa ukuhamba komoya ngokuthe nkqo kwicala elinye, ukhetho lokuhla koxinzelelo lwesihluzo nalo lubaluleke kakhulu, nto leyo efuna ukuba ukulahleka koxinzelelo kwisihluzo kungaphambuki.
(2). Uthelekiso phakathi kwenkqubo ye-FFU kunye nenkqubo yefeni ye-axial flow
I-FFU yiyunithi yokubonelela ngomoya enefeni kunye nesihluzi (ULPA). Emva kokuba umoya ufunxwe yifeni ye-centrifugal ye-FFU, uxinzelelo oluguqukayo luguqulwa lube luxinzelelo olungaguqukiyo kwi-air duct kwaye luvuthelwe ngokulinganayo yi-ULPA. Uxinzelelo lokubonelela ngomoya eluphahleni luxinzelelo olubi, ukuze kungabikho luthuli oluya kuvuza kwigumbi elicocekileyo xa isihluzi sitshintshwa. Uvavanyo lubonise ukuba inkqubo ye-FFU ingcono kunenkqubo yefeni yokuhamba kwe-axial ngokubhekiselele kufana kwe-air outlet, ukuhambelana komoya kunye ne-ventilation efficiency index. Oku kungenxa yokuba ukuhambelana komoya kwenkqubo ye-FFU kungcono. Ukusetyenziswa kwenkqubo ye-FFU kunokwenza ukuhamba komoya kwigumbi elicocekileyo kucwangciswe ngcono.
(3). Impembelelo yesakhiwo se-FFU
I-FFU ikakhulu yenziwe ngamafeni, izihluzi, izixhobo zesikhokelo sokuhamba komoya kunye nezinye izinto. Isihluzi esisebenza kakuhle kakhulu i-ULPA sesona siqinisekiso sibalulekileyo sokuba igumbi elicocekileyo lingafikelela na kucoceko olufunekayo loyilo. Izinto ezisetyenzisiweyo kwisihluzi ziya kuchaphazela ukufana kwendawo yokuhamba. Xa kongezwa izinto zesihluzi ezirhabaxa okanye ipleyiti yokuhamba yelaminar kwindawo yokuphuma yesihluzi, indawo yokuphuma kwesihluzi inokwenziwa ifane ngokulula.
2. Impembelelo yeendlela ezahlukeneyo zokucocwa kwesantya
Kwigumbi elifanayo elicocekileyo, phakathi kwendawo yokusebenza nendawo engasebenziyo yokuhamba ngokuthe nkqo okuhamba ngasekunene, ngenxa yomahluko kwisantya somoya kwindawo yokuphuma ye-ULPA, kuya kuveliswa isiphumo se-vortex exutyiweyo kwindawo yokubonakalayo, kwaye olu jongano luya kuba yindawo yokuhamba komoya oguquguqukayo enoxinzelelo olukhulu lomoya. Amasuntswana anokudluliselwa kumphezulu wesixhobo aze angcolise izixhobo kunye nee-wafers.
3. Impembelelo yabasebenzi kunye nezixhobo
Xa igumbi elicocekileyo lingenanto, iimpawu zokuhamba komoya kwigumbi zihlala zihlangabezana neemfuno zoyilo. Nje ukuba izixhobo zingene kwigumbi elicocekileyo, abasebenzi bayashukuma kwaye iimveliso zithunyelwa, kuya kubakho imiqobo ekulungelelanisweni kokuhamba komoya. Umzekelo, kwiikona ezivelelayo okanye emaphethelweni esixhobo, igesi iya kuphambukiswa ukuze yenze indawo eguquguqukayo, kwaye ulwelo olukwindawo aluthwalwa lula yigesi, nto leyo ebangela ungcoliseko. Kwangaxeshanye, umphezulu wesixhobo uya kufudumala ngenxa yokusebenza okuqhubekayo, kwaye i-gradient yobushushu iya kubangela indawo yokubuyela umva kufutshane nomatshini, nto leyo eya kwandisa ukuqokelelana kwamasuntswana kwindawo yokubuyela umva. Kwangaxeshanye, ubushushu obuphezulu buya kubangela ukuba amasuntswana aphume ngokulula. Isiphumo esiphindwe kabini senza kube nzima ukulawula ucoceko olupheleleyo lwe-laminar. Uthuli oluvela kubasebenzi kwigumbi elicocekileyo kulula kakhulu ukulunamathela kwii-wafers kwezi ndawo zokubuyela umva.
4. Impembelelo yomgangatho womoya obuyayo
Xa ukumelana komoya obuyayo odlula kumgangatho kwahlukile, kuya kuvela umahluko woxinzelelo, ukuze umoya uhambe kwicala elingaxhathisi kangako, kwaye ukuhamba komoya okufanayo akuyi kufunyanwa. Indlela yoyilo ethandwayo ngoku kukusebenzisa imigangatho ephakamileyo. Xa izinga lokuvula imigangatho ephakamileyo liyi-10%, isantya sokuhamba komoya kubude bokusebenza begumbi sinokusasazwa ngokulinganayo. Ukongeza, kufuneka kunikwe ingqalelo engqongqo kumsebenzi wokucoca ukuze kuncitshiswe umthombo wongcoliseko lomgangatho.
5. Isiganeko sokungenisa
Le nto ibizwa ngokuba yi-induction phenomenon ibhekisa kwinto yokuba umoya ohamba kwicala elichaseneyo nomsinga ofanayo uveliswa, kwaye uthuli oluvela kwigumbi okanye uthuli olukwindawo engcolileyo ekufutshane luveliswa kwicala elinyukayo, ukuze uthuli lungcolise itshiphusi. Ezi zilandelayo zezona zinto zinokwenzeka:
(1). Ipleyiti engaboniyo
Kwigumbi elicocekileyo elinokuhamba okuthe nkqo okuya kwicala elinye, ngenxa yamalungu eludongeni, kukho iipleyiti ezinkulu ezingaboniyo eziya kubangela ukuxinana kokuhamba kokubuyela kwendawo.
(2). Izibane
Izibane ezikwigumbi elicocekileyo ziya kuba nempembelelo enkulu. Ekubeni ubushushu bezibane ze-fluorescent bubangela ukuba ukuhamba komoya kunyuke, akuyi kubakho ndawo iphazamisayo phantsi kwezibane ze-fluorescent. Ngokubanzi, izibane kwigumbi elicocekileyo zenziwe ngendlela efana ne-teardrop ukunciphisa impembelelo yezibane kwilungiselelo lokuhamba komoya.
(3.) Izikhewu phakathi kweendonga
Xa kukho izikhewu phakathi kwezahlulo ezinemigangatho eyahlukeneyo yococeko okanye phakathi kwezahlulo kunye neesilingi, uthuli oluvela kwindawo enemiqathango ephantsi yococeko lungadluliselwa kwindawo ekufutshane enemiqathango ephezulu yococeko.
(4). Umgama phakathi komatshini nomgangatho okanye udonga
Ukuba umsantsa phakathi komatshini nomgangatho okanye udonga mncinane kakhulu, uya kubangela ukujijeka kwakhona. Ngoko ke, shiya umsantsa phakathi kwezixhobo nodonga uze uphakamise umatshini ukuze uphephe ukuvumela umatshini ukuba uchukumise umhlaba ngokuthe ngqo.
