Iyunithi yesihlungi sabalandeli be-FFU iyithuluzi elidingekayo lamaphrojekthi ekamelo ahlanzekile. Futhi iyiyunithi yesihlungi sokuhambisa umoya egumbini elingenalo uthuli. Kudingeka futhi kumabhentshi okusebenza ahlanzeke kakhulu kanye nedokodo elihlanzekile.
Ngokuthuthuka komnotho kanye nokuthuthukiswa kwezinga lokuphila kwabantu, abantu banezidingo eziphakeme neziphakeme zekhwalithi yomkhiqizo. I-FFU inquma ikhwalithi yomkhiqizo ngokusekelwe kubuchwepheshe bokukhiqiza nendawo yokukhiqiza, ephoqa abakhiqizi ukuthi baphishekele ubuchwepheshe bokukhiqiza obungcono.
Izinkambu ezisebenzisa amayunithi okuhlunga abalandeli be-FFU, ikakhulukazi izinto zikagesi, ezemithi, ukudla, i-bioengineering, ezokwelashwa, nezindawo zokucwaninga, zinezidingo eziqinile ngendawo yokukhiqiza. Ihlanganisa ubuchwepheshe, ukwakhiwa, ukuhlobisa, ukuhlinzekwa kwamanzi kanye ne-drainage, ukuhlanzwa komoya, i-HVAC kanye ne-air conditioning, ukulawula okuzenzakalelayo kanye nobunye ubuchwepheshe obuhlukahlukene. Izinkomba zobuchwepheshe eziyinhloko zokulinganisa ikhwalithi yendawo yokukhiqiza kulezi zimboni zihlanganisa izinga lokushisa, umswakama, ukuhlanzeka, umthamo womoya, ukucindezela okuhle kwangaphakathi, njll.
Ngakho-ke, ukulawula okunengqondo kwezinkomba ezihlukahlukene zobuchwepheshe zendawo yokukhiqiza ukuze kuhlangatshezwane nezidingo zezinqubo ezikhethekile zokukhiqiza sekuphenduke enye yezindawo zamanje zocwaningo kubunjiniyela bamagumbi ahlanzekile. Kusukela ngeminyaka yawo-1960, kwasungulwa igumbi lokuqala lomhlaba elihlanzekile lokugeleza kwe-laminar. Izicelo ze-FFU seziqalile ukuvela selokhu yasungulwa.
1. Isimo samanje sendlela yokulawula ye-FFU
Njengamanje, i-FFU ivamise ukusebenzisa izinjini ze-AC ezinesivinini esikhulu esinesigaba esisodwa, amamotho e-EC anesivinini esikhulu. Kukhona cishe ama-voltage anikezela amandla ama-2 weyunithi yesihlungi se-FFU fan: 110V kanye ne-220V.
Izindlela zayo zokulawula zihlukaniswe ngokuyinhloko ngezigaba ezilandelayo:
(1). Ukulawula ukushintsha kwamasivinini amaningi
(2). Ukulawula ukulungisa isivinini esingenasinyathelo
(3). Ukulawula ikhompuyutha
(4). Isilawuli kude
Okulandelayo ukuhlaziya okulula nokuqhathanisa izindlela ezine zokulawula ezingenhla:
2. Ukulawula ukushintshwa kwe-FFU okunesivinini esikhulu
Isistimu yokulawula ukushintshwa kwamasivinini amaningi ihlanganisa kuphela iswishi yokulawula isivinini kanye neswitch yamandla eza ne-FFU. Njengoba izingxenye zokulawula zihlinzekwa yi-FFU futhi zisatshalaliswa ezindaweni ezihlukahlukene ophahleni lwegumbi elihlanzekile, izisebenzi kufanele zilungise i-FFU ngokusebenzisa inkinobho ye-shift esizeni, okuyinto enzima kakhulu ukuyilawula. Ngaphezu kwalokho, ububanzi obulungisekayo besivinini somoya se-FFU bukhawulelwe kumazinga ambalwa. Ukuze unqobe izici eziphazamisayo zokusebenza kokulawula kwe-FFU, ngokuklanywa kwamasekhethi kagesi, wonke ama-speed switches e-FFU afakwe phakathi futhi afakwa kukhabhinethi phansi ukuze kuzuzwe ukusebenza okuphakathi. Nokho, kungakhathaliseki ukuthi ubukeka kanjani Noma kukhona ukulinganiselwa ekusebenzeni. Izinzuzo zokusebenzisa indlela yokulawula ukushintsha okunesivinini esikhulu ziwukulawula okulula kanye nezindleko eziphansi, kodwa kukhona ukushiyeka okuningi: njengokusebenzisa amandla aphezulu, ukungakwazi ukulungisa isivinini ngokushelela, akukho signali yempendulo, nokungakwazi ukufeza ukulawulwa kweqembu okuguquguqukayo, njll.
3. Ukulawulwa kokulungiswa kwesivinini esingenasinyathelo
Uma kuqhathaniswa nendlela yokulawula isivinini esinamajubane amaningi, isilawuli sokushintsha isivinini esingenasinyathelo sinesinye isilawuli sejubane esingenasinyathelo, esenza isivinini sabalandeli be-FFU sishintshe ngokuqhubekayo, kodwa futhi sidela ukusebenza kahle kwemoto, okwenza ukusetshenziswa kwayo kwamandla kuphakame kunokulawula okushintshwa kwamasivinini amaningi. indlela.
- Ukulawula ikhompuyutha
Indlela yokulawula ikhompuyutha ngokuvamile isebenzisa injini ye-EC. Uma kuqhathaniswa nezindlela ezimbili ezedlule, indlela yokulawula ikhompuyutha inemisebenzi ethuthukisiwe elandelayo:
(1). Ngokusebenzisa imodi yokulawula esabalalisiwe, ukuqapha okuphakathi nendawo nokulawula kwe-FFU kungenziwa kalula.
(2). Iyunithi eyodwa, amayunithi amaningi kanye nokulawula ukwahlukanisa kwe-FFU kungenziwa kalula.
(3). Uhlelo lokulawula oluhlakaniphile lunemisebenzi yokonga amandla.
(4). Isilawuli kude esingazikhethela singasetshenziselwa ukuqapha nokulawula.
(5). Isistimu yokulawula inokuxhumana okugodliwe okungakwazi ukuxhumana nekhompuyutha yokusingatha noma inethiwekhi ukuze kuzuzwe ukuxhumana okukude nemisebenzi yokuphatha. Izinzuzo ezivelele zokulawula amamotho e-EC yilezi: ukulawula okulula kanye nobubanzi besivinini. Kodwa le ndlela yokulawula futhi inamaphutha athile abulalayo:
(6). Njengoba ama-FFU motors engavunyelwe ukuba namabhulashi ekamelweni elihlanzekile, wonke ama-FFU motors asebenzisa ama-brushless EC motors, futhi inkinga yokuguqulwa ixazululwa abagibeli be-electronic. Impilo emfushane yabagibeli be-elekthronikhi yenza yonke impilo yesevisi yesistimu yokulawula yehliswe kakhulu.
(7). Lonke uhlelo luyabiza.
(8). Izindleko zokuyilungisa kamuva ziphezulu.
5. Indlela yokulawula kude
Njengesengezo sendlela yokulawula ikhompuyutha, indlela yesilawuli kude ingasetshenziswa ukulawula i-FFU ngayinye, ehambisana nendlela yokulawula ikhompuyutha.
Ukufingqa: izindlela ezimbili zokulawula zokuqala zinokusetshenziswa kwamandla okuphezulu futhi akulula ukuzilawula; izindlela ezimbili zokugcina zokulawula zinesikhathi esifushane sokuphila kanye nezindleko eziphezulu. Ingabe ikhona indlela yokulawula engafinyelela ukusetshenziswa kwamandla okuphansi, ukulawula okulula, impilo yesevisi eqinisekisiwe, kanye nezindleko eziphansi? Yebo, leyo yindlela yokulawula ikhompuyutha usebenzisa i-AC motor.
Uma kuqhathaniswa namamotha e-EC, amamotho e-AC anochungechunge lwezinzuzo ezifana nesakhiwo esilula, usayizi omncane, ukukhiqiza okulula, ukusebenza okuthembekile, kanye nenani eliphansi. Njengoba bengenazo izinkinga zokuhamba, impilo yabo yesevisi yinde kakhulu kunaleyo yamamotho e-EC. Isikhathi eside, ngenxa yokusebenza kwayo okungekuhle kokulawula isivinini, indlela yokulawula isivinini ibisetshenziswa indlela yokulawula isivinini ye-EC. Kodwa-ke, ngokuvela nokuthuthukiswa kwemishini emisha yamandla kagesi kanye namasekethe amakhulu ahlanganisiwe, kanye nokuvela okuqhubekayo nokusetshenziswa kwemibono emisha yokulawula, izindlela zokulawula i-AC ziye zathuthuka kancane kancane futhi ekugcineni zizothatha indawo yezinhlelo zokulawula isivinini ze-EC.
Ngendlela yokulawula ye-FFU AC, ihlukaniswe kakhulu ngezindlela ezimbili zokulawula: indlela yokulawula ukulawulwa kwamandla kagesi kanye nendlela yokulawula ukuguqulwa kwemvamisa. Indlela ebizwa ngokuthi i-voltage regulation control iwukuba ulungise isivinini semoto ngokushintsha ngokuqondile i-voltage ye-motor stator. Ububi bendlela yokulawula i-voltage yilezi: ukusebenza kahle okuphansi ngesikhathi sokulawulwa kwesivinini, ukushisisa okunamandla kwemoto ngesivinini esiphansi, kanye nebanga lokulawula ijubane elincane. Kodwa-ke, ububi bendlela yokulawula i-voltage abukho sobala kakhulu ekulayisheni kwabalandeli be-FFU, futhi kunezinzuzo ezithile ngaphansi kwesimo samanje:
(1). Uhlelo lokulawula isivinini luvuthiwe futhi uhlelo lokulawula isivinini luzinzile, olungaqinisekisa ukusebenza okuqhubekayo okungenazinkinga isikhathi eside.
(2). Kulula ukusebenza kanye nezindleko eziphansi zohlelo lokulawula.
(3). Njengoba umthwalo we-FFU fan ulula kakhulu, ukushisa kwemoto akubi kakhulu ngesivinini esiphansi.
(4). Indlela yokulawula i-voltage ifaneleka ngokukhethekile kumthwalo wabalandeli. Njengoba ijika lomsebenzi wabalandeli be-FFU liyijika eliyingqayizivele lokudambisa, uhla lokulawula isivinini lungaba banzi kakhulu. Ngakho-ke, esikhathini esizayo, indlela yokulawula i-voltage izophinde ibe yindlela enkulu yokulawula isivinini.
