Iyunithi yesihluzo sefeni ye-FFU sisixhobo esifunekayo kwiiprojekthi zegumbi elicocekileyo. Ikwayiyunithi yesihluzo somoya esibalulekileyo kwigumbi elicocekileyo elingenathuli. Ikwayimfuneko nakwiibhentshi zomsebenzi ezicocekileyo kakhulu kunye ne-booth ecocekileyo.
Ngophuhliso loqoqosho kunye nokuphuculwa kwemigangatho yokuphila yabantu, abantu banemfuno ephezulu nephezulu yomgangatho wemveliso. I-FFU imisela umgangatho wemveliso ngokusekelwe kubuchwepheshe bemveliso kunye nendawo yemveliso, nto leyo enyanzela abavelisi ukuba balandele ubuchwepheshe bemveliso obungcono.
Iindawo ezisebenzisa iiyunithi zesihluzi se-FFU fan, ngakumbi izixhobo ze-elektroniki, amayeza, ukutya, ubunjineli bebhayoloji, ezonyango, kunye neelebhu, zineemfuno ezingqongqo kwindawo yemveliso. Idibanisa itekhnoloji, ulwakhiwo, ukuhombisa, ukuhanjiswa kwamanzi kunye nokutsalwa kwamanzi, ukucocwa komoya, i-HVAC kunye ne-air conditioning, ulawulo oluzenzekelayo kunye nezinye iindlela zobuchwepheshe ezahlukeneyo. Izalathisi eziphambili zobugcisa zokulinganisa umgangatho wendawo yemveliso kwezi shishini ziquka ubushushu, ukufuma, ucoceko, umthamo womoya, uxinzelelo oluhle lwangaphakathi, njl.
Ngoko ke, ulawulo olufanelekileyo lwezalathisi ezahlukeneyo zobugcisa kwindawo yemveliso ukuhlangabezana neemfuno zeenkqubo zemveliso ezikhethekileyo luye lwaba yenye yezona ndawo ziphambili zophando kubunjineli begumbi elicocekileyo. Kwasekuqaleni kweminyaka yoo-1960, kwaphuhliswa igumbi lokuqala elicocekileyo emhlabeni. Ukusetyenziswa kwe-FFU kuqalile ukuvela ukususela ekusekweni kwayo.
1. Imeko yangoku yendlela yolawulo lwe-FFU
Okwangoku, i-FFU isebenzisa ngokubanzi ii-motor ze-AC ezinesantya esiphezulu esinye, ii-motor ze-EC ezinesantya esiphezulu esinye. Kukho ii-voltage zombane ezimalunga nezimbini ze-motor ye-FFU fan filter unit: 110V kunye ne-220V.
Iindlela zayo zokulawula zahlulwe kakhulu kwezi ndidi zilandelayo:
(1). Ulawulo lokutshintsha olunesantya esininzi
(2). Ulawulo lohlengahlengiso lwesantya olungenazitebhisi
(3). Ulawulo lwekhompyutha
(4). Ulawulo olukude
Oku kulandelayo luhlalutyo olulula kunye nothelekiso lweendlela ezine zolawulo ezingasentla:
2. Ulawulo lokutshintsha olunesantya esiphezulu lwe-FFU
Inkqubo yolawulo lokutshintsha isantya esinesantya esininzi ibandakanya kuphela iswitshi yokulawula isantya kunye neswitshi yombane eza neFFU. Ekubeni izinto zolawulo zibonelelwa yiFFU kwaye zisasazwa kwiindawo ezahlukeneyo eluphahleni lwegumbi elicocekileyo, abasebenzi kufuneka balungise iFFU ngeswitshi yokutshintsha kwindawo, nto leyo engathandekiyo kakhulu ukuyilawula. Ngaphezu koko, uluhlu oluhlengahlengiswayo lwesantya somoya seFFU lunqunyelwe kumanqanaba ambalwa. Ukuze koyiswe izinto ezingathandekiyo zokusebenza kolawulo lweFFU, ngoyilo lweesekethe zombane, zonke iiswitshi zeFFU ezinesantya esininzi zabekwa kwindawo enye zaza zabekwa kwikhabhathi emhlabeni ukuze kufezekiswe ukusebenza okuphakathi. Nangona kunjalo, kungakhathaliseki ukuba zibonakala okanye kukho imida ekusebenzeni. Iingenelo zokusebenzisa indlela yokulawula utshintsho oluninzi kukulawula okulula kunye neendleko eziphantsi, kodwa kukho iziphene ezininzi: njengokusetyenziswa kwamandla aphezulu, ukungakwazi ukulungisa isantya kakuhle, ukungabikho kwesignali yempendulo, kunye nokungakwazi ukufikelela kulawulo oluguquguqukayo lweqela, njl.
3. Ulawulo lohlengahlengiso lwesantya olungenazinyathelo
Xa kuthelekiswa nendlela yokulawula iswitshi enesantya esininzi, ulawulo lohlengahlengiso lwesantya olungenasinyathelo lunomlawuli wesantya ongezelelweyo ongenasinyathelo, okwenza isantya sefeni seFFU sihlengahlengiswe rhoqo, kodwa sikwanciphisa ukusebenza kakuhle kwenjini, okwenza ukusetyenziswa kwamandla kwayo kube phezulu kunendlela yokulawula iswitshi enesantya esininzi.
- Ulawulo lwekhompyutha
Indlela yokulawula ikhompyutha ngokubanzi isebenzisa i-EC motor. Xa kuthelekiswa neendlela ezimbini zangaphambili, indlela yokulawula ikhompyutha inemisebenzi elandelayo ephambili:
(1). Ukusebenzisa imo yolawulo esasazwe, ukubeka esweni kunye nolawulo lwe-FFU oluphakathi kunokuphunyezwa ngokulula.
(2). Iyunithi enye, iiyunithi ezininzi kunye nolawulo lokwahlulahlula lwe-FFU lunokuphunyezwa ngokulula.
(3). Inkqubo yokulawula ekrelekrele inemisebenzi yokonga amandla.
(4). Ulawulo olukude olunokukhethwa lungasetyenziselwa ukujonga nokulawula.
(5). Inkqubo yolawulo inomdibaniso wonxibelelwano ogciniweyo onokunxibelelana nekhompyutha okanye inethiwekhi ukuze kufezekiswe imisebenzi yonxibelelwano nolawulo olukude. Iingenelo ezibalaseleyo zokulawula iimoto ze-EC zezi: ulawulo olulula kunye nomgama wesantya esibanzi. Kodwa le ndlela yolawulo ikwanazo nezinye iziphene ezibulalayo:
(6). Ekubeni iimoto ze-FFU zingavumelekanga ukuba neebhrashi kwigumbi elicocekileyo, zonke iimoto ze-FFU zisebenzisa iimoto ze-EC ezingenamabhrashi, kwaye ingxaki yokutshintsha ixazululwa zii-commutators ze-elektroniki. Ubomi obufutshane bee-commutators ze-elektroniki benza ubomi benkonzo yenkqubo yolawulo yonke bunciphe kakhulu.
(7). Yonke le nkqubo ibiza kakhulu.
(8). Iindleko zokugcina izinto kamva ziphezulu.
5. Indlela yokulawula kude
Njengesongezelelo kwindlela yokulawula ikhompyutha, indlela yokulawula kude ingasetyenziselwa ukulawula i-FFU nganye, ehambelana nendlela yokulawula ikhompyutha.
Ukushwankathela: iindlela ezimbini zokuqala zokulawula zinokusetyenziswa kwamandla aphezulu kwaye azilula ukuzilawula; iindlela ezimbini zokugqibela zokulawula zinobomi obufutshane kunye neendleko eziphezulu. Ngaba ikho indlela yokulawula enokufikelela ekusetyenzisweni kwamandla okuphantsi, ulawulo olulula, ubomi benkonzo obuqinisekisiweyo, kunye neendleko eziphantsi? Ewe, leyo yindlela yokulawula ikhompyutha esebenzisa i-AC motor.
Xa kuthelekiswa neemoto ze-EC, iimoto ze-AC zineenzuzo ezininzi ezifana nesakhiwo esilula, ubungakanani obuncinci, ukwenziwa okulula, ukusebenza okuthembekileyo, kunye nexabiso eliphantsi. Ekubeni zingenazo iingxaki zokutshintsha, ubomi bazo benkonzo bude kakhulu kunobo beemoto ze-EC. Kangangexesha elide, ngenxa yokusebenza kwayo kakubi kokulawula isantya, indlela yokulawula isantya ibisoloko isetyenziswa yindlela yokulawula isantya se-EC. Nangona kunjalo, ngokuvela nokuphuhliswa kwezixhobo ezintsha ze-elektroniki zamandla kunye neesekethe ezidibeneyo ezinkulu, kunye nokuvela okuqhubekayo kunye nokusetyenziswa kweengcamango ezintsha zolawulo, iindlela zolawulo lwe-AC ziye zaphuhliswa kancinci kancinci kwaye ekugqibeleni ziya kuthatha indawo yeenkqubo zolawulo lwesantya se-EC.
Kwindlela yokulawula i-FFU AC, yahlulwe ngokubanzi kwiindlela ezimbini zokulawula: indlela yokulawula ummiselo we-voltage kunye nendlela yokulawula ukuguqulwa kwamaza. Indlela ebizwa ngokuba yindlela yokulawula ummiselo we-voltage kukulungisa isantya semoto ngokutshintsha ngokuthe ngqo umbane we-stator yemoto. Iingxaki zendlela yokulawula umbane zezi: ukusebenza okuphantsi ngexesha lokulawula isantya, ukufudumeza okukhulu kwemoto ngesantya esiphantsi, kunye noluhlu oluncinci lokulawula isantya. Nangona kunjalo, iingxaki zendlela yokulawula umbane azibonakali kakhulu kumthwalo wefeni ye-FFU, kwaye kukho ezinye izibonelelo phantsi kwemeko yangoku:
(1). Inkqubo yokulawula isantya ivuthiwe kwaye inkqubo yokulawula isantya izinzile, nto leyo enokuqinisekisa ukusebenza okungapheliyo okungenazingxaki ixesha elide.
(2). Kulula ukuyisebenzisa kwaye inexabiso eliphantsi lenkqubo yokulawula.
(3). Ekubeni umthwalo wefeni ye-FFU ulula kakhulu, ubushushu bemoto abubi bukhulu kakhulu xa isantya siphantsi.
(4). Indlela yokulawula i-voltage ifanelekile ngokukodwa kumthwalo wefeni. Ekubeni i-FFU fan duty curve iyi-damping curve eyahlukileyo, uluhlu lokulawula isantya lunokuba banzi kakhulu. Ke ngoko, kwixesha elizayo, indlela yokulawula i-voltage nayo iya kuba yindlela ephambili yokulawula isantya.
