2. Khatello e feletseng: e bua ka khatello e hlahisoang ke fan, hangata sesebelisoa ke PASCAL (Pa), boholo ba khatello e tsitsitseng e ama ka ho toba hore na fan e ka fana ka molumo o lekaneng oa moea. Litšebeliso tse fapaneng li tla lumellana le litlhoko tse fapaneng tsa tsamaiso ea moea le litlhoko tsa khatello, tse tla ama ka ho toba mofuta oa fan o hlokahalang, joalo ka li-axial flow fans, molumo oa moea o tloaelehileng o batla o le monyenyane, 'me khatello e nyenyane; Ho na le mefuta e mengata ea libapali tsa centrifugal, 'me e ka aroloa ka mefuta e mengata ho latela boholo ba khatello, joalo ka li-fans tsa centrifugal tse nang le khatello e tlase: joalo ka 4-72 series centrifugal fans, 4-73 series centrifugal fans, 4-79 series. libapali tsa centrifugal; Medium khatello centrifugal Fans: tse kang Y5-51 letoto centrifugal Fans, 6-24, 6-35, 6-42 letoto centrifugal Fans, 7-28 letoto centrifugal Fans; Bafani ba khatello e phahameng ba kang :8-09 series centrifugal fans, 9-12 series centrifugal fans, 10-18 series centrifugal fans, 8-39 series centrifugal fans, 9-38 series centrifugal fans joalo-joalo.

3 Matla: e bua ka matla a motlakase kapa a mochini a hlokoang ke fan, hangata ka li-watts (W), ha u khetha fan, ho hlokahala ho leka-lekanya matla a fan le molumo o hlokahalang oa moea le khatello e tsitsitseng. Ha u khetha koloi, u lokela ho nahana ka ntlha e itseng ea tšireletso, ke hore, u lokela ho khetha motlakase o nang le matla a mangata ho feta a hlokahalang.

4. Lerata: le bolela lerata le hlahisoang ke fene nakong ea ts'ebetso, hangata ka li-decibel (dB), 'me litekanyetso tsa lerata tse amehang tsa tikoloho li hloka ho nahanoa ha ho khethoa fan. Ka kakaretso, re tla sebelisa sebaka se tloaelehileng ho tloha mohloling oa molumo e le tekanyetso.

1. Centrifugal Fan: Ke mofuta o atileng haholo oa fene, o ka sebelisoang litsing tsa moea, tsamaiso ea moea, lisebelisoa tsa indasteri, joalo-joalo.

2. Axial fan: Ke fan e nyane e lebelo le holimo, e loketseng lisebelisoa tsa moea le lisebelisoa tsa indasteri.

3. Fen e tsoakaneng: Ke fan pakeng tsa fan ea centrifugal le axial fan, e ka bang le melemo ea bobeli ho isa tekanyong e itseng.

4. Jet fan: Ke fan e nyane e lebelo le holimo, e loketseng moea oa lehae le sistimi ea mouoane ea karache e ka tlas'a lefatše.

5. Dc fan: ke mofuta o mocha oa fan, o nang le melemo ea ho boloka matla, e sebetsang hantle, e khutsitseng le e meng, e loketseng matla a tlaase, lisebelisoa tse nyenyane tsa moea le ho senya mocheso.

1. Maemo a tikoloho: Lekola maemo a tikoloho a hlokang moea kapa mouoane, joalo ka mocheso oa moea, mongobo, lerole, joalo-joalo.

2. Tšebeliso ea Fan: Etsa qeto ea tšebeliso ea ho sebetsa ea fene, ho kenyelletsa le moea oa moea, ho ntša moea, ho senya mocheso, joalo-joalo.

3. Khanyetso ea li-duct: Bolelele ba duct, setsoe, filthara, joalo-joalo tse hlokehang bakeng sa moea kapa moea oa ho qeta moea o tla tlisa khanyetso e eketsehileng ho fan, 'me likhatello tse tsitsitseng tsa fan li lokela ho khethoa ka tsela e nepahetseng.

4. Mokhoa oa ho fana ka matla le ho laola: Khetha mokhoa o loketseng oa ho fana ka matla le mokhoa oa ho laola, ho kenyelletsa phepelo ea motlakase ea AC, motlakase oa DC, taolo ea lebelo la elektronike, switch automatic, joalo-joalo.

5. Boemo ba ho kenya: Khetha sebaka se loketseng sa ho kenya, ho kenyelletsa fatše, ho phahamisa, lerako, joalo-joalo.

[Qetello] Khetho ea balateli ke ts'ebetso e hloahloa le e rarahaneng, e hlokang ho shebisisa lintlha tse ngata. Ha ho khethoa balateli, re lokela ho nahana ka botlalo ka tikoloho ea sebele le tšebeliso, ho latela melao ea motheo ea khetho ea fan, e le ho etsa bonnete ba hore ho khethoa fan e loketseng ka ho fetisisa.
