Kukonza Patsamba

A. I. Kuyang'anira Kasamalidwe

1. Onani Malo Ogwirira Ntchito

a) Palibe kutayikira kwa refrigerant komwe kumaloledwa m'chipindamo musanatumikire.

b) Kupuma kosalekeza kuyenera kusungidwa panthawi yokonza.

c) Moto wotseguka kapena magwero otentha kwambiri opitilira 370 ° C (omwe amatha kuyatsa moto) amaletsedwa m'malo osamalira.

d) Panthawi yokonza: Ogwira ntchito onse ayenera kuzimitsa mafoni a m'manja. Zipangizo zamagetsi zowunikira ziyenera kutsekedwa.

Munthu m'modzi, single-unit, single-zone ntchito imalimbikitsidwa kwambiri.

e) Ufa wouma kapena chozimitsira moto cha CO2 (pogwira ntchito) chiyenera kupezeka pamalo okonzera.

1. Kuyang'anira Zida Zosamalira

a) Tsimikizirani kuti zida zokonzera ndizoyenera pafiriji yapampu ya kutentha. Ingogwiritsani ntchito zida zaukadaulo zomwe zimalimbikitsidwa ndi wopanga pampu yotentha.

b) Yang'anani ngati zida zodziwira kutayikira mufiriji zasinthidwa. Kuyika kwa alamu kuyenera kupitirira 25% ya LFL (Lower Flammability Limit). Zipangizozi ziyenera kukhala zikugwira ntchito panthawi yonse yokonza.

1. R290 Kuyendera Pampu Yotentha

a) Onetsetsani kuti pampu yotentha yakhazikika bwino. Onetsetsani kuti nthaka ikupitirirabe komanso kukhazikika kodalirika musanagwiritse ntchito.

b) Tsimikizirani kuti mphamvu ya mpope wa kutentha yatha. Musanayambe kukonza, kulumikiza magetsi ndi kutulutsa ma capacitor onse a electrolytic mkati mwa unit. Ngati mphamvu yamagetsi ikufunika panthawi yokonza, kuyang'anira kosalekeza kwa kutuluka kwa firiji kuyenera kuchitidwa m'malo omwe ali pachiopsezo chachikulu kuti apewe zoopsa.

c) Onani momwe zilembo zonse zilili ndi zolembera. Sinthani zilembo zochenjeza zomwe zawonongeka, zotha, kapena zosamveka.

B. Kuzindikira Kutayikira Kusanachitike - Kukonza malo

1. Pamene pampu yotentha ikugwira ntchito, gwiritsani ntchito chojambulira chodumphira kapena chojambulira (pomp - suction type) yomwe imalimbikitsidwa ndi wopanga pampu yotentha (onetsetsani kuti kukhudzidwa kumakwaniritsa zofunikira ndipo kwasinthidwa, ndi kutayikira kwa 1 g / chaka ndi chojambulira chojambulira chenjezo chosapitirira 25% ya LEL) kuti muwone ngati mpweya watsikira. Chenjezo: madzimadzi ozindikira ngati akutuluka ndi oyenera mufiriji ambiri, koma musagwiritse ntchito zosungunulira zomwe zili ndi klorini kuti mupewe dzimbiri za mapaipi amkuwa chifukwa cha zomwe zimachitika pakati pa chlorine ndi refrigerant.
2. Ngati mukukayikira kuti pali kutayikira, chotsani magwero onse amoto pamalopo kapena kuzimitsa motowo. Onetsetsani kuti malowo ali ndi mpweya wabwino.
3. Zolakwa zimene amafuna kuwotcherera wa mkati refrigerant mapaipi.
4. Zolakwa zomwe zimafunika kusokoneza dongosolo la firiji kuti likonzedwe.

C. Mikhalidwe Yomwe Kukonzekera Kuyenera Kuchitikira ku Malo Othandizira

1. Zolakwa zimene amafuna kuwotcherera wa mkati refrigerant mapaipi.
2. Zolakwa zomwe zimafunika kusokoneza dongosolo la firiji kuti likonzedwe.

D. Njira Zosamalira

1. Konzani zida zofunika.
2. Kukhetsa refrigerant.
3. Yang'anani kuchuluka kwa R290 ndikuchotsani dongosolo.
4. Chotsani zolakwika zakale.
5. Chotsani makina ozungulira a refrigerant.
6. Onani kuchuluka kwa R290 ndikusintha magawo atsopano.
7. Chokani ndikulipiritsa ndi R290 refrigerant.

E. Mfundo Zachitetezo Panthawi Yokonza Pamalo

1. Posamalira mankhwala, malowa ayenera kukhala ndi mpweya wokwanira. Ndizoletsedwa kutseka zitseko zonse ndi mazenera.
2. Moto wotseguka ndi woletsedwa panthawi yokonza, kuphatikizapo kuwotcherera ndi kusuta. Kugwiritsa ntchito mafoni am'manja nakonso ndikoletsedwa. Ogwiritsa adziwitsidwe kuti asagwiritse ntchito moto wotseguka pophika, ndi zina.
3. Munthawi yokonza nyengo zowuma, chinyezi chikakhala pansi pa 40%, njira zotsutsana ndi ma static ziyenera kuchitidwa. Izi zikuphatikizapo kuvala zovala za thonje zoyera, kugwiritsa ntchito zipangizo zotsutsana ndi ma static, ndi kuvala magolovesi a thonje opanda kanthu pamanja onse.
4. Ngati nsonga yoyaka mufiriji ipezeka pakukonza, njira zopumira mpweya nthawi yomweyo ziyenera kuchitidwa, ndipo gwero la kutayikira liyenera kutsekedwa.
5. Ngati kuwonongeka kwa mankhwalawa kumafuna kutsegula firiji kuti ikonzedwe, iyenera kutumizidwa ku malo okonzerako kuti ikagwire. Kuwotcherera mapaipi a refrigerant ndi ntchito zofananira ndizoletsedwa m'malo a wogwiritsa ntchito.
6. Ngati mbali zowonjezera zikufunika pakukonza ndipo ulendo wachiwiri ukufunika, pampu ya kutentha iyenera kubwezeretsedwa ku chikhalidwe chake choyambirira.
7. Ntchito yonse yokonza iyenera kuonetsetsa kuti firiji imakhazikika bwino.
8. Popereka ntchito pamalopo ndi silinda ya refrigerant, kuchuluka kwa refrigerant yodzazidwa mu silinda sikuyenera kupitilira mtengo womwe watchulidwa. Silinda ikasungidwa mgalimoto kapena kuyikidwa pamalo oikirapo kapena kukonza, iyenera kuyikika motetezeka, kutali ndi magwero otentha, magwero a moto, magwero a radiation, ndi zida zamagetsi.
