Yankho la AHU Retrofit Lomwe Limapulumutsa CNY 3.43 Miliyoni Pachaka mu Ndalama Zamagetsi

Pa nthawi yonse ya moyo wa nyumba zamalonda, kugwiritsa ntchito mphamvu kumakhalabe vuto lalikulu.

Makina a HVAC amapanga pafupifupi 40% mpaka 60% ya mphamvu yonse yomwe nyumbayo imagwiritsa ntchito. Monga "mtima" womwe umapereka kuziziritsa ndi kutentha pamene ukuonetsetsa kuti mpweya uli bwino m'nyumba, kugwira ntchito bwino kwa Air Handling Units (AHUs) kumatsimikizira mwachindunji momwe mphamvu zonse zimagwirira ntchito.

Pakati pa kukakamiza kuti mpweya usalowerere komanso kukwera kwa ndalama zogwirira ntchito, mafani achikhalidwe nthawi zambiri sakwaniritsa zosowa zosungira mphamvu. Kodi mphamvu zosungira mphamvu zingatsegulidwe bwanji m'nyumba zomwe zilipo kale?

Pulojekiti yaposachedwa ya AHU yokonzanso zinthu ku malo ogulitsira zinthu ku Tianjin yapereka zotsatira zoyezeka:

Kusunga mphamvu kwa 64.25%.

Pansipa pali tsatanetsatane wa momwe EC fan ukadaulo unathandizira pa izi.

1. Kusintha Kobiriwira kwa Malo Ogulitsira Okhazikika

Malo ogulitsira awa, omwe ali m'dera lamalonda lodzaza ndi anthu ambiri, akhala akugwira ntchito kwa zaka zambiri ndipo amakumana ndi anthu ambiri oyenda pansi tsiku lililonse.

Patapita nthawi, mayunitsi oyambirira a AHU anayamba kusonyeza zizindikiro za kukalamba ndi kutopa.

- Mafani oyambilira oyendetsedwa ndi lamba adawonongeka kwambiri chifukwa cha kugwiritsidwa ntchito kwa nthawi yayitali, zomwe zidapangitsa kuti akhale gwero lalikulu lamagetsi ambiri.

- Zigawo zofunika monga malamba ndi mabearing zinali zitatha, zomwe zimafuna kusinthidwa ndi kukonzedwa pafupipafupi—kuwonjezera ndalama zogwirira ntchito komanso ntchito yokonza.

- Magawo akale analibe ulamuliro wolondola, zomwe zinapangitsa kuti malamulo olondola a kutentha akhale ovuta komanso kukhudza momwe zinthu zimayendera.

- Popeza anali ndi nzeru zochepa, mayunitsi 46 sanapereke ndemanga yeniyeni pa momwe ntchito ikuyendera, zomwe zimafuna khama lalikulu loyang'anira ndi manja.

Pofuna kuthandizira zolinga za dziko lonse zosunga mphamvu ndi kuchepetsa utsi woipa komanso kuchepetsa ndalama zogwirira ntchito, oyang'anira malo ogulitsira anaganiza zochita kukonzanso kwathunthu kwa ma AHU 46 awa.

Izi sizinali kungosintha zida chabe—zinali kusintha kwathunthu kwa njira yoyendetsera mphamvu ya malo ogulitsira.

2. Kuyesa Koyambirira

Kusintha kwa mphamvu kumafuna kupanga zisankho motsatira deta.

Poyamba ntchitoyi, gulu la akatswiri linafufuza bwino momwe AHU inalili kale:

Dzina Loyambirira la Fan

● Kuyesa Mphamvu Yogwirira Ntchito - Kugwiritsa ntchito mphamvu yeniyeni ya AHU iliyonse kunayesedwa.

● Kuyeza Kupanikizika Kosasunthika & Kuyenda kwa Mpweya - Mzere wozungulira wa mafani oyambilira pansi pa mikhalidwe yeniyeni ya duct unayesedwa, zomwe zinapereka deta yofunika kwambiri posankha mafani a EC.

● Kuyang'anira Phokoso - Phokoso loyambira linalembedwa kuti lithandizire kusintha kwa mawu.

● Kuyeza Kukula kwa Malo Oyikira - Kuyeza kwa millimeter kunatsimikizira kuti zipangizo zatsopano zikugwirizana bwino ndi zipinda zomwe zilipo kale.

● Kuwunika Motsatira Mita - Deta ya mphamvu yeniyeni inasonkhanitsidwa kudzera mu dongosolo loyang'anira nyumba kuti zithandize kufananiza mphamvu pambuyo pa kukonzanso.

Deta yolondola ya m'munda inalola gululo kudzipereka molimba mtima ku ndalama zomwe linkayembekezera ndipo linapereka maziko olimba osankha mafani oyenera a EC.

3. Mafani a EC: Kumanga Mtima Wogwira Ntchito

Kutengera ndi deta yowunikira mwatsatanetsatane, gulu laukadaulo linapanga njira yokonzanso zinthu ya ma AHU 46.

Njira yaikulu inali yolowa m'malo mwa mafani a EC.

Mafani 165 a EC amphamvu kwambiri adayikidwa, makamaka pogwiritsa ntchito mitundu iwiri: A3E-3A630-Y8-58 ndi A3E-3A560-Y8-56.

Seemtek Achelous Series EC Fans

Chifukwa chiyani mafani a EC?

- Mafani a EC ali ndi ma mota okhazikika a maginito ogwirizana.
Poyerekeza ndi ma mota achikhalidwe a AC induction, amachotsa kutayika kwa rotor ndikusunga magwiridwe antchito apamwamba ngakhale atakhala ndi katundu pang'ono—chinthu chofala kwambiri pamakina a HVAC amalonda. Deta ikuwonetsa kuti ma mota a EC amatha kuchita bwino kwambiri kuposa 90%.

- Ma AHU achikhalidwe nthawi zambiri amagwira ntchito pa liwiro lokhazikika, zomwe zimapangitsa kuti mphamvu zambiri ziwonongeke.
Mafani a EC amathandizira kulumikizana kwa 0–10V kapena RS485/MODBUS, zomwe zimathandiza kusintha liwiro mosalekeza kutengera kuchuluka kwa anthu ndi kutentha komwe kumachitika.

- Ndi kapangidwe kakang'ono komanso ntchito yoyendetsa mwachindunji, mafani a EC amachotsa kufunikira kwa malamba.
Kwa magulu okonza, izi zikutanthauza kuti sipadzakhalanso kusintha lamba kapena kuyeretsa fumbi la lamba, zomwe zimachepetsa kwambiri kukonza kwa AHU nthawi zonse.

Pa nthawi yokonza, gululi linatsatira mfundo ya kukula kolondola. Mwa kugwiritsa ntchito kusinthasintha kwa kukhazikitsa mafani a EC (khoma la mafani), anaonetsetsa kuti zofunikira zonse za mpweya zikukwaniritsidwa pamene akukonza momwe magetsi amagwiritsidwira ntchito komanso mtengo wake.

4. Kukonzanso Kosasokoneza

Kuchita ntchito yosintha AHU yayikulu m'malo ogulitsira zinthu kunabweretsa mavuto azachuma. Kukula kochepa komanso kulemera kochepa kwa mafani atsopano a EC kunakhala kothandiza m'zipinda zotsekedwa zamakina. Pofuna kupewa kusokoneza ntchito za malo ogulitsira zinthu, gulu la polojekitiyi linatsatira njira yokhazikika isanaperekedwe zida:

- Kuyang'anira maziko

- Malo oika mafani

- Kuteteza ndi kulumikizana

- Mawaya amagetsi

Khoma la Fan la Seemtek EC

Chifukwa cha kapangidwe ka mafani a EC, zovuta zoyika zidachepa kwambiri. Zomwe zidatenga masiku angapo kuti AHU ikonzedwenso zidachepetsedwa mpaka maola 6 okha (kuchotsa mafani akale + kukhazikitsa atsopano).

Kukhazikitsa zida zamagetsi kunali gawo loyamba chabe. Luntha lenileni la makinawa lili m'manja mwa wowongolera wake.

Chiyankhulo Chosinthira Chowongolera

Akangoyika, gulu laukadaulo linaphatikiza mafani a EC mu dongosolo loyang'anira nyumba (BMS). Kudzera mu kukonza bwino ndi chowongolera, ma AHU adasintha kuchoka pakupereka mpweya wokhazikika wosavuta mpaka kufika pakugwira ntchito mwanzeru:

- Kusintha kayendedwe ka mpweya kuti kuziziritsa kapena kutentha kusakhale kofanana

- Kuwongolera liwiro la fan yokha kutengera kutentha kwa mpweya wobwerera, kuchotsa kuzizira kwambiri kapena kutentha kwambiri

5. Kupeza Mphamvu Yosungira 64.25%

Kuwerenga mita yamagetsi isanayambe komanso itatha kukonzanso kumatsimikizira zotsatira zake.

Gome ili pansipa likuyerekeza deta kuchokera ku AHU-1 kwa masiku 10 isanayambe komanso itatha kukonzanso:

Deta ikuwonetsa bwino kuchepa kwakukulu kwa kugwiritsa ntchito mphamvu kwa AHU iyi, pamodzi ndi kuchepa kwakukulu kwa mphamvu yogwira ntchito.

Kutengera ndi kuwerengera, AHU imodzi iyi idapeza mphamvu zosungira mphamvu za 64.25%.

Ndikofunikira kudziwa kuti iyi si malire apamwamba, chifukwa makinawa ankagwira ntchito pa mphamvu yayikulu kwambiri panthawi yoyezerayi. Pambuyo powonjezera njira zowongolera monga kutentha kosasintha, kuyenda kwa mpweya kosasintha, ndi kupanikizika kosasintha—ndi kusintha ku kulamulira kotengera kutentha pa Novembala 23—kugwiritsa ntchito mphamvu kunatsika ndi 67% yowonjezera.

6. Nkhani Yachuma

Popeza mafani ankagwira ntchito pa liwiro lokhazikika, ankagwira ntchito ndi mphamvu zonse (27.57 kW) chaka chonse mosasamala kanthu za nyengo kapena katundu. Mtengo wamagetsi wapachaka unali wokhazikika ndipo unali wokwera:

Mtengo wamagetsi pachaka = 27.57 kW × maola 13.5/tsiku × masiku 365 × 0.77 yuan/kWh ≈104,600 yuan

Ndi mafani a EC ogwira ntchito bwino komanso zowongolera zanzeru, AHU imasintha liwiro la mafani kutengera kutentha kwa mpweya wobwerera, zomwe zimachepetsa kwambiri mphamvu yogwirira ntchito. Ntchito yapachaka idagawidwa m'magawo atatu kuti muyesere:

● Mtengo wonse wamagetsi pachaka mutakonzanso magetsi = 7,370 + 12,898 + 9,827 ≈ 30,100 yuan

● Ndalama zosungidwa pachaka pa AHU** = 104,600 – 30,100 = 74,500 yuan

● Ndalama zonse zomwe zasungidwa pachaka za 46 AHUs: 46 × 74,500 ≈ 3.43 miliyoni yuan

Pamene njira zochepetsera mpweya woipa zikuchulukirachulukira, kukweza kwa AHU komwe kumayang'ana kwambiri ukadaulo wa mafani a EC kukuyembekezeka kukhala chisankho chachikulu cha kukonzanso mphamvu m'nyumba zamalonda.
