1, Chidule cha Zamalonda
Chotsukira mpweya champhamvu cha basi ndi chipangizo chapadera chotsukira ndi kusungunula galasi lakutsogolo la mabasi amagetsi/osakanikirana/mafuta. Pakati pake pamagwiritsa ntchito zinthu zotenthetsera kutentha za PTC ceramic positive temperature coefficient, zomwe zimagwirizana ndi nsanja ya DC ya batire yamagetsi ya 400V/600V/800V, yokhala ndi 24V low-voltage control, blower yodziyimira payokha, duct ya mpweya, dera lotetezeka lamphamvu komanso gawo lowongolera kulumikizana kwa CAN. Ndi gawo lofunikira kwambiri pakuwongolera kutentha kwa nyengo yozizira komanso chitetezo cha masomphenya atsopano.
Mitundu iwiri yodziwika bwino ya kapangidwe ka nyumba
Mtundu wotentha mwachindunji wouma (defroster ya mpweya wodziyimira pawokha ya PTC)
Mpweya wotentha mwachindunji, bokosi lodziyimira pawokha, fani yomangidwa mkati, yopanda mapaipi amadzi, yomwe imagwiritsidwa ntchito kwambiri pamabasi ang'onoang'ono a mamita 6-8 ndi mabasi akutsogolo, okhala ndi mphamvu ya 3-12kW;
Madzi ophatikizidwa ndi makina otenthetsera (madzi ozizira ndi kuthamanga kwa PTC kothamanga kwambiri)
Choletsa kuzizira cha PTC champhamvu kwambiri, chomwe chimasinthanitsa kutentha ndi thanki ya mpweya wofunda kuti chipange mpweya wotentha, chingalumikizidwe ndi kutentha kwa batri ndi kutentha kwa magalimoto. Chimagwiritsidwa ntchito makamaka pamabasi opitilira mamita 10 ndi mabasi omwe ali m'malo okwera, okhala ndi mphamvu ya 10-30 kW.
2, mfundo yogwirira ntchito
1. Mfundo yogwiritsira ntchito kutentha kouma mwachindunji pogwiritsa ntchito mphamvu yamagetsi (yomwe imagwiritsidwa ntchito kwambiri)
Mphamvu yamagetsi yamphamvu kwambiri: Batire yamagetsi yagalimoto imatulutsa mphamvu ya 400-800V DC, yomwe imalumikizidwa ku chinthu chotenthetsera cha PTC. Chingwe chowongolera chamagetsi otsika a 24V ndi basi ya CAN zimalandira malamulo osungunula kuchokera ku panelo yoziziritsira mpweya/VCU;
Kutentha kwa PTC kodziletsa: Barium titanate ceramic semiconductor imakhala ndi kukana kochepa kwambiri kutentha kochepa ndipo imatentha mofulumira ikayaka; Kutentha kukakwera kufika pa mfundo ya Curie (100-120 ℃), chizindikiro cha kukana chimakwera kwambiri, zomwe zimachepetsa mphamvu ya kutentha yokha. Imatha kusunga kutentha kosasintha ndikuletsa kuyaka kouma popanda kufunikira valavu yowonjezera yowongolera kutentha;
Kusamutsa kutentha kwa mpweya: Yokhala ndi fan yamphamvu kwambiri yolumikizira mpweya/yodutsa mpweya kuti ikoke mpweya wabwino kuchokera mkati/kunja kwa galimoto, imayenda mofulumira kwambiri kudzera m'thupi lotulutsa kutentha la PTC aluminiyamu, ndipo mpweya umatenthedwa mwachangu;
Mpweya wosungunuka molunjika: Mpweya wotentha umawulutsidwa mofanana mkati mwa galasi lakutsogolo kudzera mu payipi yapadera ya mpweya, kusungunula chisanu ndi nthunzi ya madzi yomwe imatuluka;
Ma loops angapo achitetezo: sensa yokhazikika mkati, HVIL yolumikizira magetsi ambiri, chitetezo cha overcurrent/overvoltage/heating overcurrent, kudula kokha kutentha kwa high voltage pamene fan yasiya, kuti isapse ndi moto wouma; Chizindikiro cha cholakwika chimakwezedwa ku alamu ya chipangizo kudzera mu CAN.
2. Mfundo ya kayendedwe ka madzi kotenthedwa ndi kuthamanga kwambiri
Chotenthetsera cha PTC champhamvu kwambiri chimatenthetsa ethylene glycol antifreeze ya galimoto yonse mpaka 60-85 ℃;
Pampu yamadzi yamagetsi imayendetsa kayendedwe ka madzi otentha kupita ku thanki yosungunula ndi yofunda ya mpweya m'dera loyendetsera;
Fani imapyola mu thanki yamadzi kuti isinthane kutentha ndikupanga mpweya wotentha, womwe umawombedwa kupita ku galasi lakutsogolo kuti usungunuke kwathunthu;
Pambuyo poziziritsa, choletsa kuzizira chimabwerera ku PTC kuti chitenthetsenso, ndipo kuzungulirako kumapitirira kutentha, komwe kumatha kutentha batire yamagetsi nthawi yomweyo kutentha kotsika.
3, ntchito zapakati
1. Ntchito zoyambira zachitetezo (zofunikira pa malamulo oyendetsera ntchito)
Kusungunuka mwachangu: Mu malo otentha pang'ono a -20 ℃, mpweya wotentha kwambiri umapangidwa kwa masekondi 30, ndipo chisanu choposa 80% chomwe chili mu giya yakutsogolo chimachotsedwa mkati mwa mphindi 20, kukwaniritsa miyezo ya chitetezo cha magalimoto apaulendo a ECE R43;
Kuchotsa utsi tsiku lonse ndi kuchotsa chinyezi: kupumira mpweya wotentha wokha kuti uchotse utsi pa mawindo amkati ndikuchotsa kusawona bwino masiku amvula komanso kusiyana kwakukulu kwa kutentha; Kungachititse kuti mpweya watsopano utuluke kunja kuti uchepetse chinyezi mkati mwa galimoto ndikupereka chitetezo cha nthawi yayitali ku utsi.
2. Chithandizo chotenthetsera magalimoto
Kutentha kodziyimira pawokha kwa malo a dalaivala. Mitundu ina yolumikizidwa imathandizira kusintha kwa njira yopumira mpweya m'njira zitatu monga kupumira mapazi, kupumira nkhope ndi kusungunula, poganizira kutentha ndi kusungunula dalaivala;
Chotenthetsera madzi chimagwirizana ndi makina otenthetsera galimoto, poganizira momwe mpweya wofunda umatulutsira m'dera la okwera.
3. Ntchito yanzeru yowongolera zamagetsi
Basi ya CAN imagwira ntchito ndi VCU ya galimotoyo komanso chowongolera mpweya, kusintha mphamvu yotenthetsera malinga ndi kutentha kwa chilengedwe ndi chinyezi cha galasi (ndi mphamvu zambiri zosinthika);
Njira yodzitetezera yokha: Ngati fani yalephera kugwira ntchito, kutentha kwambiri, kutayikira kwa mphamvu yamagetsi ambiri, kapena kulephera kutenthetsa, nthawi yomweyo dulani alamu yamagetsi ambiri ndi zida;
Kusintha kutentha kwambiri ndi kotsika: Mphamvu yotulutsa mphamvu yonse kutentha kochepa, kuchepetsa mphamvu yokha komanso kutentha kosasintha mutafika pamlingo wofunikira kutentha kwa chipinda, kuchepetsa kugwiritsa ntchito mphamvu.
4. Ntchito zokulitsa (zokhazokha pa zitsanzo za mapaipi)
Kutentha pang'ono kwa batire yamagetsi: Yatsani choziziritsira cha batire pamalo otsika kwambiri kuti batire igwire ntchito bwino kwambiri pa 20-30 ℃, kupewa kutsika kwa madzi m'malo otsetsereka komanso kuyika ndalama zochepa;
Kubwezeretsa kutentha kwa zinyalala: Kubwezeretsa kutentha kwa zinyalala kuchokera ku ma mota ndi zowongolera zamagetsi kuti zithandize kutentha ndikuchepetsa kugwiritsa ntchito mphamvu kwa PTC yamagetsi amphamvu.
