Ukadaulo wa Fan Wosinthasintha wa Liwiro mu Air Conditioning

Ukadaulo wa Fan Wosinthasintha wa Liwiro mu Air Conditioning

Ukadaulo wa mpweya woziziritsa (AC) ukupitirirabe kusintha kuti ukhale ndi mphamvu zambiri, chitonthozo, komanso kusamala chilengedwe. Ngakhale kuti mayunitsi a AC ankadziwika kale kuti amagwira ntchito ndi "kuzima kwathunthu", zomwe zimapangitsa kuti kutentha kusinthe kwambiri, mayunitsi ambiri amakono tsopano akusintha kupita ku machitidwe owongolera osalala komanso osinthika. Chinthu chimodzi chofunikira chomwe chikuthandizira kuti izi zigwire bwino ntchito komanso chitonthozo ndi ukadaulo wa mafani osinthasintha - mafani okhala ndi liwiro lomwe angasinthidwe momwe angafunikire. Ukadaulo uwu si chinthu chongowonjezera, koma ndi gawo lofunikira kwambiri pa kapangidwe kamakono ka AC, komwe kamapangitsa kuti dongosolo lonse lizigwira ntchito bwino.

Kodi ma Fan a Variable Speed ​​​​ndi ati?

Mafani othamanga mosiyanasiyana ndi mafani omwe ali pa mayunitsi a AC amkati kapena akunja omwe amatha kugwira ntchito pa liwiro losiyanasiyana (RPM), osati "pang'onopang'ono" komanso "mwachangu" monga mafani wamba. Liwiro la mafani limayendetsedwa ndi ma electronic circuits ndi masensa, nthawi zambiri kudzera mu DC motor (brushless DC motor/BLDC) kapena inverter-controlled AC motor. Njirayi imalola fan kusintha kayendedwe ka mpweya ndi kutentha, kutengera zosowa za chipindacho nthawi iliyonse.

Ponena za AC, pali malo awiri akuluakulu a fan:

1. Fani ya m'nyumba (fani ya evaporator): ntchito yake ndikufalitsa mpweya wa m'chipinda kudzera mu evaporator kuti mpweya wotuluka ukhale wozizira komanso chinyezi chichepetse.
2. Fani yakunja (fani ya condenser): imathandiza kuchotsa kutentha kuchokera ku condenser kupita kumalo akunja, zomwe zimapangitsa kuti kuthamanga ndi kutentha kwa firiji zikhale bwino.

Onse awiri akhoza kugwiritsa ntchito ukadaulo wosinthasintha liwiro kuti apeze zotsatira zabwino kwambiri.

Momwe Imagwirira Ntchito mu Dongosolo Lamakono la AC

Mu ma air conditioner achizolowezi, compressor nthawi zambiri imagwira ntchito mu laun/off mode, zomwe zimapangitsa kuti kutentha kusinthe. Mu inverter air conditioner, compressor imatha kuzungulira pa liwiro losiyanasiyana, kusintha mphamvu yozizira. Mafani osinthasintha amawonjezera lingaliro ili: pamene kuzizira kuli kochepa, fan sikufunika kuzungulira mofulumira; pamene katundu akuwonjezeka, fan imadzithamanga yokha.

Dongosolo lowongolera la AC lidzawerenga magawo angapo, monga:

- kutentha kwa chipinda ndi malo okhazikika,
- kutentha kwa evaporator ndi condenser,
- kupanikizika kwa firiji (m'mapangidwe ena),
- chinyezi ndi mpweya wabwino (pa mitundu ina),
- liwiro la kompresa.

Kutengera ndi deta iyi, chowongolera chimasankha kuphatikiza koyenera kwa liwiro la compressor ndi liwiro la fan kuti kutentha kukhale kokhazikika komanso kukulitsa magwiridwe antchito.

Ubwino Waukulu wa Mafani Othamanga Osiyanasiyana

1. Kusunga Mphamvu Zenizeni
Mafani ndi katundu wolemera kwambiri wamagetsi. Ngakhale kuti mphamvu ya mafani nthawi zambiri imakhala yotsika poyerekeza ndi ya ma compressor, ndalama zomwe zimasungidwa zimakhalabe zazikulu chifukwa fani imagwira ntchito nthawi yonse yomwe chipangizocho chikugwira ntchito. Mwa kuchepetsa RPM panthawi yodzaza ndi zinthu zochepa, mphamvu ya fani imachepanso. Chofunika kwambiri, kulamulira bwino kayendedwe ka mpweya kumathandiza kuti makina oziziritsira azigwira ntchito bwino, zomwe zimalepheretsa compressor kugwira ntchito mopitirira muyeso.

Zotsatira zake: kugwiritsa ntchito mphamvu mokhazikika komanso mwina kotsika, makamaka pakugwiritsa ntchito kwa nthawi yayitali monga m'nyumba, m'maofesi, kapena m'malo amalonda.

2. Kutentha Kokhazikika Kwambiri, Chitonthozo Chokhazikika Kwambiri
Ngati fani ili ndi njira ziwiri kapena zitatu zokha, kusintha kwa kayendedwe ka mpweya kumatha kumveka "mwadzidzidzi": kuwonjezeka mwadzidzidzi kapena kuchepa kwa kayendedwe ka mpweya. Ndi liwiro losinthasintha, kusinthaku kumachitika bwino. Kuyenda kwa mpweya kokhazikika kumathandiza kusunga kutentha kwa chipinda kokhazikika, kuchepetsa kumverera kwa "nthawi yozizira, kenako kutentha kachiwiri" komwe kumawoneka nthawi zambiri m'makina akale.

Kuphatikiza apo, dongosololi limatha kusunga kuziziritsa kwa kuwala kosalekeza popanda kuyima kwathunthu, zomwe zimapangitsa kuti likhale losangalatsa kwambiri.

3. Chete
Kuthamanga pang'ono kwa mafani kumatanthauza phokoso lochepa. Ma air conditioner ambiri amakono amadalira mafani osinthasintha kuti akwaniritse njira "zosagona" kapena "zogona" ndi phokoso lochepa. Izi ndizothandiza makamaka m'zipinda zogona, masukulu, ma studio, kapena chipinda chilichonse chomwe chimafuna phokoso lochepa.

Pa mayunitsi akunja, mafani osinthasintha amathanso kuchepetsa phokoso la chilengedwe, makamaka m'malo okhala anthu ambiri kapena m'nyumba zomwe mayunitsiwo amakhala pafupi.

4. Kulamulira Bwino Chinyezi
Kuziziritsa chipinda sikungokhudza kutentha kokha, komanso chinyezi. Kuti muchepetse chinyezi, mpweya uyenera kudutsa mu evaporator, zomwe zimalola nthunzi ya madzi kuzizira. Fani yokhala ndi liwiro losinthika imalola choziziritsira mpweya kulinganiza kuchepetsa kutentha ndi kuchotsa chinyezi.

Muzochitika zina, fani yamkati yomwe imachedwa pang'ono imatha kuchotsa chinyezi mwa kulola mpweya kukhala wolumikizana ndi evaporator kwa nthawi yayitali. Komabe, makina amakono amawongolera izi kuti chipindacho chisamve kuzizira kwambiri.

5. Moyo Wautali wa Chigawo
Kusintha kwa liwiro losalala kumachepetsa kupsinjika kwa makina pa injini ya fan ndi zida zina zogwirizana nazo. Kuphatikiza apo, kuwongolera kutentha kokhazikika komanso kuthamanga kwa mpweya kumathandiza kuchepetsa ntchito ya compressor. Ngakhale kuti nthawi ya moyo wa chipangizocho imakhudzidwa ndi zinthu zambiri (ubwino wa chipangizocho, kukhazikitsa kwake, ndi kukonza), mafani osinthasintha amathandizira kuti ntchito iyende bwino komanso kuchepetsa katundu wogwedezeka.

Maukadaulo Ogwiritsa Ntchito Magalimoto ndi Kuwongolera Kawirikawiri

Njinga ya BLDC (yopanda burashi DC)
Ma air conditioner ambiri amakono amagwiritsa ntchito ma BLDC motors kwa mafani amkati ndi akunja. Ubwino wawo ndi monga kugwira ntchito bwino kwambiri, kuwongolera liwiro molondola, komanso phokoso lochepa. Mtundu uwu wa mota umagwiritsa ntchito magetsi oyendera magetsi kuti asinthe, m'malo mwa maburashi omwe amawonongeka ndi ma DC motors achizolowezi.

Inverter ndi PWM Control
Kulamulira liwiro nthawi zambiri kumachitika pogwiritsa ntchito njira monga PWM (Pulse Width Modulation) kapena inverter control pa ma mota ena. Ndi PWM, mphamvu zamagetsi "zimadulidwa" mwachangu kuti liwiro la mota lithe kusinthidwa bwino popanda kutaya mphamvu zambiri ku kutentha.

Masensa ndi Ma Algorithms Olamulira
Kagwiridwe ka ntchito ka mafani osinthasintha kamadalira masensa otenthetsera, masensa amakono, ndi njira zowongolera. Ma model apamwamba nthawi zambiri amakhala ndi ma algorithms osinthika kwambiri, monga omwe amaganizira zosintha mawonekedwe a katundu m'chipinda, momwe amagwiritsidwira ntchito, kapena kuzindikira momwe zinthu zilili usiku.

Mavuto ndi Zinthu Zoyenera Kuzisamala

Ngakhale kuti ili ndi zabwino zambiri, ukadaulo uwu umabweretsanso zotsatirapo zake:

1. Mtengo wokwera woyambira: Mayunitsi okhala ndi ma mota a BLDC ndi zowongolera zapamwamba nthawi zambiri amakhala okwera mtengo kuposa mayunitsi wamba a AC.
2. Kuvuta kwa ntchito: Popeza pali ma module amagetsi, kuzindikira zolakwika kumafuna akatswiri aluso komanso zida zokwanira.
3. Ubwino ndi kukhazikitsa magetsi: Mphamvu yamagetsi yosakhazikika kapena kukhazikitsa koyipa kungakhudze kudalirika kwa gawo lowongolera. Chifukwa chake, kukhazikitsa kokhazikika ndi kugwiritsa ntchito chokhazikika (ngati kuli kofunikira) kuyenera kuganiziridwa.

Komabe, nthawi zambiri, kusiyana koyambirira kwa mtengo kumatha kuchepetsedwa ndi kusunga mphamvu kwa nthawi yayitali komanso chitonthozo, makamaka ngati choziziritsira mpweya chikugwiritsidwa ntchito tsiku ndi tsiku.

Mapeto

Ukadaulo wa mafani osinthasintha ndi chinthu chofunikira kwambiri pakusintha kwa mpweya wamakono. Pokhala ndi luso losintha liwiro la mafani, ma air conditioner amatha kugwira ntchito bwino kwambiri, mopanda phokoso, kusunga kutentha nthawi zonse, komanso kuwongolera bwino chinyezi. Ukadaulo uwu umathandizanso magwiridwe antchito onse a ma inverter AC, chifukwa makina oziziritsira samadalira kokha compressor komanso kulumikizana kwa zigawo zonse—kuphatikizapo mafani amkati ndi akunja.

Kwa ogwiritsa ntchito omwe amaika patsogolo chitonthozo cha tsiku ndi tsiku komanso kugwiritsa ntchito mphamvu moyenera, kusankha choziziritsira mpweya chokhala ndi mafani osinthasintha ndikomveka. Pakati pa kufunikira kwa mphamvu zambiri komanso kufunikira kwa moyo wabwino, ukadaulo uwu ukuwonetsa momwe zatsopano zosavuta mu zigawo za mafani zingakhudzire kwambiri zomwe zimachitika pa choziziritsira mpweya.
