Isixhobo sokupholisa sibizwa ngokuba yi-chiller, eyinxalenye ebalulekileyo yenkqubo yokupholisa umoya kwiziko ledatha. I-refrigerant ngokubanzi ngamanzi, ibizwa ngokuba yi-chiller. Ukupholisa kwe-condenser kufezekiswa ngokutshintshiselana kobushushu kunye nokupholisa amanzi obushushu obuqhelekileyo, ngoko ke ikwabizwa ngokuba yiyunithi epholiswe ngamanzi. . Iziko ledatha linesidingo esikhulu somthamo wokupholisa, kwaye ukusebenza kakuhle kwamandla kunokufunyanwa ngokukhetha iyunithi ye-centrifugal. I-chiller kweli nqaku ibhekisa ngokukodwa kwiyunithi ye-centrifugal.
I-compressor yefriji ye-centrifugal yi-compressor yesantya esijikelezayo. Umbhobho wokufunxa ungenisa igesi eza kucinezelwa kwi-impeller inlet. Igesi ijikeleza ngesantya esiphezulu kunye ne-impeller phantsi kwesenzo see-impeller blades. Igesi iyasebenza, isantya segesi siyanda, ize emva koko itsalwe kwindawo ephumayo ye-impeller, ize ingeniswe kwigumbi le-diffuser; ekubeni igesi iphuma kwi-impeller, inesantya esiphezulu sokuhamba, ukuze iguqule le nxalenye yesantya ibe ngamandla oxinzelelo, i-diffuser enecandelo lokuhamba elikhuliswe kancinci kancinci ifakelwe ukuguqula amandla ukwandisa uxinzelelo lwegesi; emva kokuba igesi esasazekileyo iqokelelwe kwi-volute, ingena kwi-condenser yeyunithi ukuze ifunxe. Inkqubo engentla yi-centrifuge. Umgaqo wokucinezelwa, njengoko kubonisiwe kuMfanekiso 1; Ukongeza, ukuze ifunxe kwaye isuse ubanda, inkqubo yomoya iquka inkqubo yamanzi okupholisa kunye nenkqubo yamanzi abandayo.
01
Ulwakhiwo lweyunithi yeCentrifugal
Ulwakhiwo lweyunithi ye-centrifugal lulandelayo: kuquka i-centrifugal compressor, i-evaporator, i-condenser, i-throttling orifice, isixhobo sokubonelela ngeoyile, ikhabhinethi yokulawula, njl.njl., njengoko kubonisiwe kuMfanekiso 2 nakuMfanekiso 3. I-compressor yenziwe ikakhulu yigumbi lokufunxa, i-impeller, i-diffuser, i-bend kunye nesixhobo se-reflux, kunye ne-volute.
Iimpawu zeyunithi ye-centrifugal
Iimpawu zeyunithi enkulu ye-centrifuge zezi zilandelayo:
1. Umthamo omkhulu wokupholisa. Ekubeni umthamo wokufunxa wecompressor ye-centrifugal ungenakuba mncinci kakhulu, umthamo wokupholisa weyunithi enye wecompressor ye-centrifugal mkhulu kakhulu. Ulwakhiwo oluncinci, ubunzima obulula kunye nobukhulu obuncinci, ngoko ke ithatha indawo encinci. Phantsi komthamo ofanayo wokupholisa, ubunzima becompressor ye-centrifugal yi-1/5 ukuya kwi-1/8 kuphela yowecompressor yepiston, kwaye okukhona umthamo wokupholisa umkhulu, kokukhona ucaca ngakumbi.
2. Izixhobo ezingasetyenziswa kakhulu kwaye zithembekile kakhulu. Ii-centrifugal compressors azigugi phantse ngexesha lokusebenza, ngoko ke zihlala ixesha elide kwaye zineendleko eziphantsi zokulungisa nokusebenza.
3. Inxalenye yokucinezela kwi-compressor ye-centrifugal yintshukumo ejikelezayo, kwaye amandla e-radial alungelelanisiwe, ngoko ke ukusebenza kuzinzile, ukungcangcazela kuncinci, kwaye akukho sixhobo sikhethekileyo sokunciphisa ukungcangcazela esifunekayo.
4. Umthamo wokupholisa ungalungiswa ngokwezoqoqosho. Ii-centrifugal compressors zingasebenzisa iindlela ezifana nokulungiswa kwe-guide vane ukulungisa amandla ngaphakathi koluhlu oluthile.
5. Kulula ukuphumeza ucinezelo kunye nokuqhoboshela ngamanqanaba amaninzi, kwaye kunokwenza ukusebenza kunye nokusebenza kwefriji enye enamaqondo obushushu amaninzi okuphuma komphunga.
Iimpazamo eziqhelekileyo zeChillers
Umatshini obandayo uza kudibana neengxaki ezithile ngexesha lokwakhiwa nokuqaliswa kokusebenza, kwaye kuya kubakho nokusilela ngexesha lokusebenza. Ukuphathwa kwezi ngxaki kunye neziphene kunxulumene nokhuseleko lokusebenza kunye nokugcinwa kweziko ledatha. Ezi zilandelayo zezinye iimeko ezenzeke ngexesha lokwakhiwa kunye nokusebenza koomatshini ababandayo. Iindlela ezifanelekileyo zokucubungula kunye namava zenzelwe ukubhekisa kuphela.
01
Akukho kulungiswa kwemithwalo
【Ingxaki】
Iziko ledatha kufuneka lilungise kwaye livavanye i-chiller, kodwa ukufakwa kwezixhobo zomoya-moya akukagqitywa, kwaye indawo ayinayo i-dummy load efunekayo, ngoko ke umsebenzi wokuyila awunakwenziwa.
【Uhlalutyo lweengxaki】
Emva kokuba kugqityiwe ukufakwa kweyunithi ye-centrifuge kwiziko ledatha, izixhobo zesiphelo kwigumbi lekhompyutha azifakwanga, umjelo wamanzi obandayo kwisiphelo uyavalwa, kwaye i-chiller ayinakulungiswa. Umthwalo mncinci kakhulu ukuba ungafikelela kumthwalo ophantsi we-chiller, kwaye umsebenzi wokulungisa iimpazamo awunakwenziwa. Kwelinye icala, ngenxa yokuba umatshini obandayo awukalungiswa, izixhobo zeseva kwigumbi eliphambili lekhompyutha azinakusebenza kwaye zisebenze, zenze iluphu engapheliyo; ukongeza, ngexesha lenkqubo yokulungisa iimpazamo, amandla omthwalo ofunekayo makhulu, kwaye inkqubo yokusebenza iya kudla amandla amaninzi; ezi zinto zingasentla zikhokelela ekulungisweni kweengxaki zomatshini obandayo.
【Ingxaki isonjululwe】
Sebenzisa indlela yokulungisa ubushushu ngaphandle komthwalo xa ulungisa ubushushu. Le nkqubo kukusebenzisa ngokupheleleyo amandla okutshintshiselana kobushushu kwi-plate exchange, ukutshintshiselana nokubanda okuveliswe yi-evaporator yefriji ukuya kwicala le-condenser yefriji ngokusebenzisa i-plate exchange, kunye nokutshintshiselana nobushushu obukhutshwa yi-condenser yefriji ukuya kwicala le-evaporator ngokusebenzisa i-plate exchange, ukuze kufezekiswe ukuhambelana okupheleleyo phakathi kwamandla okuphola kwefriji kunye nomthwalo wobushushu, kwaye inqaba yokupholisa isusa kuphela amandla e-shaft ye-compressor. Ukusebenzisa le ndlela, kulula ukufezekisa uvavanyo olupheleleyo lokusebenza phantsi kwemithwalo eyahlukeneyo. Ukujikeleza kwesekethe yamanzi kokutshintshwa kwe-cold plate kunye nokulungisa ubushushu kuboniswe kuMfanekiso 4.
Amanyathelo okulungisa ingxaki kwinkqubo ngokusisiseko ngala alandelayo:
1. Vula ivalvu ye-bypass kwi-sub-collector, kwaye uqinisekise ukuba umzila wamanzi uvuliwe ukuze wenze ukujikeleza kwegazi xa i-terminal air conditioner ingafakwanga;
2. Vula ngokupheleleyo i-chiller kwicala lamanzi abandayo kunye nevalvu yokutshintsha ipleyiti ukuqinisekisa ukuba indlela yamanzi yokutshintsha i-chiller kunye nepleyiti igudile, kwaye amanzi abandayo atsalwa yi-chiller kunye nobushushu obubuyiswa yi-plate exchange zinokuxutywa kakuhle; ngokuqhelekileyo vula ipompo yamanzi abandayo kwaye ulungise ngesandla i-frequency ukuya kwi-45Hz okanye ngaphezulu, kwaye uqinisekise ukuba ukujikeleza kwamanzi kuqhelekile;
3. Vula ngokupheleleyo ivalvu yamanzi okupholisa ye-chiller, vula ivalvu kancinci kwicala lamanzi okupholisa kwindawo yokutshintsha iphaneli, uze uvule ipompo yamanzi okupholisa ukuqinisekisa ukujikeleza kwamanzi okuqhelekileyo. Lungisa i-frequency yepompo ibe yi-41-45Hz; musa ukuvula ifeni yenqaba yokupholisa kuqala;
4. Phantsi kweemeko eziqhelekileyo zamanzi abandayo namanzi okupholisa, vula i-chiller uze wenze uvavanyo oluzimeleyo;
5. Ubushushu bamanzi abandayo kwi-chiller buqala ukunyuka, kwaye amanzi abandayo aqala ukuphola;
6. Lungisa umthamo wokudlulisa ubushushu we-plate exchange ngokwendlela evuleka ngayo ivalvu yamanzi okupholisa ye-plate exchange, kwaye ulungise indlela evuleka ngayo ivalvu phakathi kwe-1/4 kunye nevuleke ngokupheleleyo;
7. Vula kancinci ifeni yenqaba yokupholisa ngokweqondo lobushushu bamanzi okupholisa, nayiphi na enokususa amandla eshafti yecompressor.
【Amava】
Ukuze kuncitshiswe ukusetyenziswa kwamandla kwaye kuqwalaselwe ukupholisa kwendalo, amaziko edatha ngokubanzi ayilwa ngetekhnoloji yokupholisa indawo yetower yokupholisa + iplate. Ngexesha lokuqalisa ukusebenza, amandla okutshintshiselana kobushushu kwiplate exchange angasetyenziselwa ukufumana ubushushu obaneleyo kwi-condenser ye-chiller njengoko umthwalo wobushushu wokuqalisa ukusebenza kwe-chiller, oko kukuthi, ubanda obuveliswa yi-chiller buthathwa yiplate exchange.
Umgaqo wokulungisa ingxaki ngaphandle komthwalo kukusebenzisa ngokupheleleyo amandla okutshintshiselana kobushushu kwi-plate exchange, ukutshintshiselana nokubanda okuveliswe yi-evaporator yefriji ukuya kwicala le-condenser yefriji nge-plate exchange, kunye nokutshintshiselana nobushushu obukhutshwa yi-condenser yefriji bubuyele kwi-evaporator nge-plate exchange Side, ukuze kufezekiswe ukufana kwamandla okuphola kunye nomthwalo wobushushu kwifriji, le ndlela ilula ukuyisebenzisa kwaye kulula ukuyisebenzisa.
