Momwe mungalipiritsire bwino galimoto yanu air conditioner

Kuwongolera mpweya wamagalimoto kumapanga microclimate yabwino mnyumbamo, ndikuchotsa kutentha kwachilimwe. Koma chowongolera mpweya chomwe chimayikidwa m'galimoto chimakhala chowopsa kuposa zida zapakhomo zofananira, chifukwa zimakhudzidwa ndi kugwedezeka uku mukuyendetsa, dothi lamsewu ndi mankhwala owopsa. Chifukwa chake, pamafunika kukonza pafupipafupi komanso kuwonjezera ma refrigerant.

Kodi zoziziritsira mpweya zimagwira ntchito bwanji mgalimoto?

Mpweya m'nyumbayo umakhazikika chifukwa cha kukhalapo kwa firiji yapadera mu dongosolo lotsekedwa la air conditioner, yomwe, pozungulira, imadutsa kuchokera ku mpweya kupita ku madzi ndi mosemphanitsa.

Compressor ya air conditioner yamagalimoto nthawi zambiri imayendetsedwa ndi lamba woyendetsa womwe umayendetsa kuzungulira kuchokera ku crankshaft. Compressor yothamanga kwambiri imatulutsa refrigerant ya gaseous (freon) mu dongosolo. Chifukwa cha kukanikizana kwakukulu, gasiyo amatenthedwa kufika pafupifupi 150°C.

Freon imalowa mu condenser (condenser), mpweya umazizira ndikukhala madzi. Njirayi imatsagana ndi kutulutsidwa kwa kutentha kwakukulu, komwe kumachotsedwa chifukwa cha mapangidwe a condenser, omwe makamaka ndi radiator ndi fan. Pakusuntha, condenser imawombedwanso ndi kutuluka kwa mpweya komwe kukubwera.

Freon ndiye amadutsa mu chowumitsira, chomwe chimasunga chinyezi chochulukirapo, ndikulowa mu valve yokulitsa. Valavu yowonjezera imayendetsa kutuluka kwa refrigerant kulowa mu evaporator kale pansi pa kupanikizika kochepa. Kuzizira kwa freon pa evaporator outlet, kumachepetsa kuchuluka kwa firiji yomwe imalowa mu evaporator kudzera mu valve.

Mu evaporator, freon amadutsa kuchokera kumadzi kupita ku mpweya chifukwa cha kuchepa kwakukulu kwa kuthamanga. Popeza njira ya evaporator imawononga mphamvu, freon ndi evaporator palokha zimakhazikika kwambiri. Mpweya wowulutsidwa ndi fani kudzera mu evaporator umakhazikika ndikulowa mchipinda chokwera. Ndipo freon pambuyo pa evaporator kudzera mu valavu imabwerera ku compressor, kumene ndondomeko ya cyclic imayambanso.

Ngati ndinu mwiniwake wa galimoto ya ku China ndipo mukufunikira kukonza mpweya, mungapeze zofunikira mu sitolo ya intaneti.

Momwe ndi kangati kudzaza choziziritsa mpweya

Mtundu wa refrigerant ndi kuchuluka kwake nthawi zambiri zimawonetsedwa pa mbale pansi pa hood kapena zolemba zautumiki. Monga ulamuliro, ndi R134a (tetrafluoroethane).

Magawo omwe adapangidwa chaka cha 1992 chisanachitike adagwiritsa ntchito R12 mtundu wa freon (difluorodichloromethane), womwe umadziwika kuti ndi m'modzi mwa owononga ozoni wosanjikiza wa Dziko Lapansi ndikuletsedwa kugwiritsidwa ntchito.

Freon imatuluka pakapita nthawi. M'ma air conditioners agalimoto, amatha kufika 15% pachaka. Ndizosafunika kwambiri kuti kutaya kwathunthu kukhale oposa theka la voliyumu yodziwika bwino ya refrigerant. Pamenepa, pali mpweya wambiri ndi chinyezi m'dongosolo. Kuthira mafuta pang'ono sikungakhale kothandiza pankhaniyi. Dongosololi liyenera kuchotsedwa ndikulipitsidwa kwathunthu. Ndipo izi, ndithudi, zimakhala zovuta komanso zodula. Choncho, m'pofunika kuti recharge ndi refrigerant kamodzi pa 3 ... 4 zaka. Musanadzaze mpweya wozizira ndi freon, ndi bwino kuyang'ana kutuluka mu dongosolo kuti musawononge ndalama, nthawi ndi khama.

Zomwe zimafunikira pakulipiritsa kwa freon

Kuti mudzaze mpweya wozizira wagalimoto ndi refrigerant nokha, mudzafunika zida izi:

- siteshoni ya manometric (otolera);

- machubu (ngati sakuphatikizidwa ndi station)

- adapter;

- mamba a khitchini amagetsi.

Ngati mukufuna kuchotsa dongosolo, ndiye kuti mudzafunikanso pampu ya vacuum.

Ndipo, ndithudi, chitini cha refrigerant.

Kuchuluka kofunikira kwa freon kumadalira chitsanzo cha mpweya wozizira, komanso ngati kuwonjezereka kwapang'onopang'ono kapena kuwonjezereka kwathunthu kumachitidwa.

kupukuta

Ndi vacuuming, mpweya ndi chinyezi zimachotsedwa m'dongosolo, zomwe zimasokoneza kugwira ntchito kwa mpweya wabwino ndipo nthawi zina zingayambitse kulephera kwake.

Lumikizani chubu kuchokera papampu ya vacuum molunjika ku chowongolera mpweya chomwe chili papaipi yotsika kwambiri, masulani nsongayo ndikutsegula valavu yomwe ili pansi pake.

Yambitsani mpope ndikulola kuti iziyenda kwa mphindi 30, ndiye zimitsani ndi kutseka valavu.

Zabwinonso, pangani kulumikizana kudzera pa manometric manifold kuti mutha kuwongolera njirayo molingana ndi miyeso ya kuthamanga. Za ichi:

- kulumikiza polowera pampu pakati koyenera kwa manometric manifold;

- kulumikiza chitoliro chotsika cha wokhometsa (buluu) kuti chigwirizane ndi malo otsika kwambiri a air conditioner,

- Lumikizani payipi yothamanga kwambiri (yofiira) ndi kutulutsa koyenera kwa kompresa ya air conditioning (mumitundu ina izi sizingakhalepo).

Yatsani mpope ndikutsegula valavu ya buluu ndi valavu yofiira pa siteshoni ya geji (ngati chubu yoyenera ikugwirizana). Lolani mpope kuyenda kwa mphindi 30. Kenako wonongani mavavu oyezera kuthamanga, zimitsani mpope ndikudula payipi kuchokera pagawo lapakati la gejiyo.

Pamaso pa choyezera chotsitsa chopondera, zowerengera zake pambuyo pothawa ziyenera kukhala mkati mwa 88 ... 97 kPa osasintha.

Pakachitika kuchuluka kwa kukakamiza, ndikofunikira kuyang'ana dongosolo la kutayikira poyesa kukakamiza popopera kuchuluka kwa freon kapena kusakaniza kwake ndi nayitrogeni mmenemo. Ndiye yankho la sopo kapena chithovu chapadera chimagwiritsidwa ntchito pamizere, zomwe zingathandize kupeza kutayikira.

Kutayikirako kukakonzedwa, bwerezaninso kutulutsa.

Tiyenera kukumbukira kuti vacuum yokhazikika sikutsimikizira kuti refrigerant sidzatuluka pambuyo poyipitsidwa mu dongosolo. N'zotheka kudziwa molondola ngati palibe kutayikira, kokha mwa kuyesa kukakamiza.

Momwe mungakulitsire mpweya wanu wozizira

1. Lumikizani siteshoni yoyezera poyambira ndi mavavu ake.

Lumikizani ndi kupukuta payipi ya buluu kuchokera pamagetsi a buluu kupita kumalo oyamwa (kudzaza), mutachotsa kale chipewa choteteza. Kuyika uku kuli pa chubu chokhuthala chopita ku evaporator.

Mofananamo, gwirizanitsani payipi yofiira kuchokera pamagetsi ofiira ofiira kupita kumalo othamanga kwambiri (kutulutsa), komwe kuli pa chubu chochepa kwambiri.

Mungafunike ma adapter kuti mulumikizane.

2. Ngati ndi kotheka, mwachitsanzo, ngati vacuum yachitidwa kale, tsanulirani mafuta apadera a PAG (polyalkylene glycol) mu jekeseni ya mafuta, yomwe ili pa payipi yachikasu yolumikizidwa ndi kuyenerera kwapakati pa siteshoni ya geji. Mafuta adzaponyedwa mu dongosolo limodzi ndi freon. Osagwiritsa ntchito mitundu ina yamafuta!

Werengani mosamala zomwe zili mu botolo la firiji. Ikhoza kukhala kale ndi mafuta. Ndiye simuyenera kudzaza mafuta mu jekeseni wamafuta. Komanso, siziyenera kuwonjezeredwa pakuwonjezera pang'ono. Mafuta ochulukirapo m'dongosolo amatha kulepheretsa ntchito ya compressor komanso kuiwononga.

3. Lumikizani mbali ina ya payipi yachikasu ku silinda ya freon kudzera pa adaputala ndi mpopi. Onetsetsani kuti mpopi wa adaputala watsekedwa musanakhome pa ulusi wa katiriji.

4. Tsegulani mpopi pa botolo la Freon. Ndiye muyenera kumasula pang'ono payipi yachikasu pa kuyenerera kwa gauge yochuluka ndikumasula mpweya kuti isalowe mu air conditioning system. Mpweya wotuluka, pukuta payipi.

5. Ikani canister ya freon pa sikelo kuti muchepetse kuchuluka kwa refrigerant yomwe imapopedwa. Sikelo yakukhitchini yamagetsi ndiyabwino.

6. Yambitsani injini ndikuyatsa choyatsira mpweya.

7. Kuti muyambe kuwonjezera mafuta, masulani valavu ya buluu pa siteshoni ya geji. Chofiira chiyenera kutsekedwa.

8. Pamene kuchuluka kofunikira kwa freon kuponyedwa mu dongosolo, zimitsani mpopi pa chitha.

Pewani kupopa mufiriji mowonjezera. Yang'anirani kupanikizika, makamaka ngati mumawonjezera mafuta ndi diso pamene simukudziwa kuti freon yatsala bwanji mu dongosolo. Pamzere wocheperako, kuyeza kwamphamvu sikuyenera kupitirira 2,9 bar. Kuthamanga kwambiri kukhoza kuwononga mpweya wozizira.

Mukamaliza kuwonjezera mafuta, yang'anani momwe mpweya wabwino umagwirira ntchito, chotsani ma hoses ndipo musaiwale kusintha zisoti zoteteza zolumikizira.
