HVAC masisitimu anovimba nemidziyo yekufemesa yekudziya nzvimbo uye mhepo yekudziya, sezvo mafirita nemaboilers ega haakwanise kuunza kupisa kana kutonhora mhedzisiro painodiwa.Pamusoro pezvo, masisitimu ekufemesa anovimbisa kugara uchipihwa mweya mutsva wenzvimbo dzemukati.Zvichienderana nedzvinyiriro uye kuyerera kwemhepo zvinodiwa zvechishandiso chega chega, ingave feni kana blower inoshandiswa.
Tisati takurukura nezvemhando huru dzemafeni uye mabheji, zvakakosha kuti unzwisise musiyano pakati pemafungiro ese.IAmerican Society of Mechanical Engineers (ASME) inotsanangura mafeni uye mafuridziro zvichienderana nereshiyo pakati pekumanikidza kuburitsa uye kusveta kumanikidza.
- Fani:Pressure ratio kusvika 1.11
- Mhepo:Pressure ratio kubva 1.11 kusvika 1.2
- Compressor:Pressure ratio inodarika 1.2
Mafeni nemafuridzo anodiwa kuti mweya ukunde kuramba kuyerera kunokonzerwa nezvikamu zvakaita semadhaidhi nemadhamu.Kune mhando dzakawanda dziripo, imwe neimwe inokodzera mamwe maapplication.Kusarudza rudzi rwakakodzera kunobatsira kukwenenzvera kuita kweHVAC, nepo kusarudzwa kwakashata kuchitungamira mukurasa simba.
Uri kushandisa midziyo yekufema yakakwana here?

Mhando dzeFani
Mafeni anogona kuverengerwa kuita centrifugal kana axial zvichienderana nemagadzirirwo avanoita mhepo.Nekudaro, kune akati wandei ma subtypes muchikamu chega chega, uye kusarudza feni inoenderana nechishandiso kwakakosha pakumisikidzwa kweHVAC kwepamusoro.
Tafura inotevera inopfupikisa mhando huru dze centrifugal mafeni: radial, mberi curved, back curved uye airfoil type.
| FAN TYPE | DESCRIPTION |
| Radial | -Kumanikidzwa kwepamusoro uye kuyerera kwepakati -Inoshivirira guruva, unyoro uye kupisa, zvichiita kuti ive yakakodzera kushandiswa kwemaindasitiri -Kushandiswa kwesimba kunowedzera zvakanyanya pamwe chete nemhepo |
| Forward curved | -Medium kudzvinyirirwa uye kuyerera kwakanyanya -Inokodzera maHVAC masisitimu ane kuderera kwakadzikama, senge akaputirwa padenga remba -Inoshivirira guruva, asi haina kukodzera kune dzakaomarara maindasitiri -Kushandiswa kwesimba kunowedzera zvakanyanya pamwe chete nemhepo |
| Backward curved | -Kumanikidzwa kwepamusoro uye kuyerera kwepamusoro -Kushanda nesimba -Haaone kuwedzera kunoshamisa kwekumanikidzwa nemhepo inoyerera -HVAC uye maindasitiri ekushandisa, zvakare akamanikidza dhizaini masisitimu |
| Airfoil | -Kumanikidzwa kwepamusoro uye kuyerera kwepamusoro -Kushanda nesimba -Yakagadzirirwa zvikumbiro nemhepo yakachena |
Kune rimwe divi, axial kuyerera mafeni akaiswa mumhando dzepropeller, chubhu axial uye vane axial.
| FAN TYPE | DESCRIPTION |
| Propeller | -Kudzvinyirira kwakaderera uye kuyerera kwepamusoro, kushanda kwakaderera -Inokodzera kudziya kuri pakati nepakati -Kuyerera kwemhepo kunoderedzwa zvakanyanya kana static pressure inowedzera. -Zvakajairwa zvikumbiro zvinosanganisira exhaust mafeni, ekunze condensers uye inotonhorera shongwe |
| Tube axial | -Medium kudzvinyirirwa uye kuyerera kwakanyanya -Cylindrical dzimba uye diki clearance ine fan blades kuti uwedzere kuyerera kwemhepo -Inoshandiswa muHVAC, exhaust masisitimu uye maapplication ekuomesa |
| Vane axial | -Kumanikidzwa kwepamusoro uye kuyerera kwepakati, kushanda kwepamusoro -Pamuviri yakafanana nechubhu axial mafeni, kubatanidza gwara vanes pakutora kuvandudza kushanda zvakanaka -Kushandiswa kwakajairika kunosanganisira HVAC uye exhaust masisitimu, kunyanya panodiwa kudzvanywa kwakanyanya |
Nekusarudzwa kwakakura kwakadaro kwevateveri, pane mhinduro kune chero application.Nekudaro, zvakasiyana zvakare zvinoreva kuti pane mukana wepamusoro wekusarudza iyo isiriyo fan pasina kutungamira kwakaringana.Kurudziro yakanakisa ndeyekudzivisa "kutonga kwechigunwe" sarudzo, uye panzvimbo pacho tora dhizaini yehunyanzvi inosangana nezvinodiwa zvepurojekiti yako.
Mhando dzeBlowers
Sezvambotaurwa, vanofuridza vanoshanda nereshiyo yekumanikidza ye1.11 kusvika 1.2, izvo zvinovaita zvepakati pakati pefani uye compressor.Ivo vanogona kuburitsa yakanyanya kumanikidza kupfuura mafeni, uye zvakare inoshanda muindasitiri vacuum application inoda kudzvanyirirwa kwakashata.Mabhowa akakamurwa kuita mapoka makuru maviri: centrifugal uye positive displacement.
Centrifugal blowersvane kumwe kufanana kwemuviri nemapombi ecentrifugal.Ivo vanowanzo sanganisira giya sisitimu yekuwana kumhanya zvakanyanya pamusoro pe10,000 rpm.Centrifugal blowers inogona kuva ne-single-stage kana ye-multi-stage yekuvaka, apo imwe-nhanho dhizaini inopa hupamhi hwepamusoro, asi iyo yakawanda-nhanho dhizaini inopa hupamhi hwekuyerera kwemhepo pakumanikidzwa kwakasimba.
Kufanana nemafeni, centrifugal blowers ane maapplication muHVAC.Nekudaro, nekuda kwehukuru hwavo hwekumanikidza kubuda, ivo vanoshandiswawo mukuchenesa michina uye mota application.Mhedzisiro yavo huru ndeyekuti kuyerera kwemhepo kunodzikira nekukurumidza kana chipingamupinyi chichisimudza kudzvanywa, zvichiita kuti dzisakodzere maapplication ane mukana wakakura wekuvhara.
Positive-displacement blowersiva nerotor geometry yakagadzirirwa kubata homwe dzemhepo, kutyaira kuyerera munzira yakarongedzerwa pakumanikidza kwakanyanya.Kunyangwe dzichitenderera nekumhanya kwakaderera pane centrifugal blowers, dzinogona kuburitsa dzvinyiriro yakakwana yekufuridza zvinhu zvinovhara system.Imwe mutsauko wakakosha ne centrifugal sarudzo ndewekuti positive-displacement blowers anowanzo fambiswa nemabhandi pane magiya.
Mhedziso
Mafeni nemafuridzo anowanzo kutsanangurwa zvichibva pakudzvanywa uye kuyerera kwemhepo zvinodiwa zvechishandiso chega chega, pamwe nenzvimbo dzakanangana nesaiti senge guruva uye tembiricha.Kana iyo chaiyo mhando ye fan kana blower yatsanangurwa, kuita kunogona kazhinji kukwidziridzwa nekutonga masisitimu.Semuyenzaniso,variable frequency drives (VFD)inogona kuderedza zvakanyanya kushandiswa kwemagetsi kwemafeni anoshanda nguva nenguva.
