Chifukwa ozizira yosungirako kompresa frosting ?

1-Zida zosungira zoziziritsa kukhosi: Frost pa doko lobwerera kwa kompresa ikuwonetsa kuti kutentha kwa kompresa ndikotsika kwambiri. Ndiye nchiyani chomwe chingapangitse kuti kompresa abwerere kutentha kwa mpweya kukhala wotsika kwambiri?

Zimadziwika bwino kuti ngati voliyumu ndi kukakamiza kwamtundu womwewo wa refrigerant kusinthidwa, kutentha kudzakhala ndi machitidwe osiyanasiyana. Ndiko kuti, ngati refrigerant yamadzimadzi imatenga kutentha kwambiri, kupanikizika, kutentha ndi kuchuluka kwa mtundu womwewo wa refrigerant zidzakhala zapamwamba. Ngati kuyamwa kwa kutentha kuli kochepa, kupanikizika, kutentha ndi voliyumu zidzakhala zochepa.

Izi zikutanthauza kuti, ngati mpweya wobwereranso wa compressor uli wotsika, umawonetsa kutsika kwa mpweya wobwerera komanso kuchuluka kwa refrigerant voliyumu yomweyo. Chomwe chimayambitsa izi ndikuti refrigerant yomwe ikuyenda kudzera mu evaporator siyingathe kuyamwa kutentha komwe kumafunikira kuti iwonjezere kupanikizika komwe kunadziwikiratu komanso kutentha, zomwe zimapangitsa kutentha kwa mpweya wobwerera, kupanikizika ndi kuchuluka kwa voliyumu.

Pali zifukwa ziwiri za vutoli:

1. The throttle valve liquid refrigerant supply ndi yabwino, koma evaporator sangathe kuyamwa kutentha kawirikawiri kuti apereke kukulitsa kwa refrigerant.

2. Evaporator imatenga kutentha nthawi zonse, koma mpweya wa throttle valve refrigerant ndi wochuluka kwambiri, ndiko kuti, kutuluka kwa firiji kumakhala kochuluka. Nthawi zambiri timamvetsetsa kuti fluorine yochulukirapo, ndiye kuti, fluorine yochulukirapo imayambitsanso kutsika kwamphamvu.

2- Zida zosungira zoziziritsa kukhosi: Kuzizira kwa kompresa kubweza mpweya chifukwa cha fluorine wosakwanira

1. Chifukwa cha kutsika kochepa kwambiri kwa refrigerant, refrigerant idzayamba kufalikira mu malo oyamba owonjezereka pambuyo potuluka kumbuyo kwa valve yotsekemera. Nthawi zambiri chisanu pamutu wogawira madzi kumapeto kwa valve yowonjezera nthawi zambiri amayamba chifukwa cha kusowa kwa fluorine kapena kusakwanira kwa valve yowonjezera. Kuwonjezako pang'ono kwa firiji sikudzagwiritsa ntchito dera lonse la evaporator, ndipo kutentha kochepa kokha kumapangidwira kumaloko mu evaporator. Madera ena amakula mofulumira chifukwa cha kuchepa kwa firiji, zomwe zimapangitsa kuti kutentha kwa m'deralo kukhale kotsika kwambiri, zomwe zimapangitsa kuti pakhale chisanu cha evaporator.

Pambuyo pa chisanu cham'deralo, chifukwa cha mapangidwe otsekera pamwamba pa evaporator ndi kutentha kochepa m'derali, kufalikira kwa firiji kudzasamutsidwa kumadera ena, ndipo evaporator yonse idzazizira pang'onopang'ono kapena kuzizira. Evaporator yonseyo ipanga chosanjikiza chotsekereza, kotero kufalikira kudzafalikira ku chitoliro chobwerera cha kompresa, kupangitsa kuti kompresa kubwereranso mpweya kukhala chisanu.

2. Chifukwa cha kuchepa kwa refrigerant, mphamvu ya evaporator evaporation imakhala yochepa, zomwe zimapangitsa kuti kutentha kwa mpweya kukhale kochepa, komwe pang'onopang'ono kumapangitsa kuti evaporator asokonezeke ndikupanga wosanjikiza, ndipo mfundo yowonjezera idzasamutsidwa ku mpweya wobwerera ku compressor, zomwe zimapangitsa kuti compressor ibwererenso mpweya ku chisanu. Mfundo zonse zomwe zili pamwambazi ziwonetsa kuti evaporator yazizira mpweya wobwerera wa kompresa usanayambe chisanu.
Ndipotu, nthawi zambiri, chifukwa cha chisanu, mumangofunika kusintha valve yotentha yodutsa mpweya. Njira yeniyeni ndiyo kutsegula chivundikiro chakumbuyo cha valve yotentha ya gasi, ndiyeno mugwiritseni ntchito nambala 8 ya hexagonal wrench kuti mutembenuzire nati yosinthira mkati mwawotchi. Kukonzekera sikuyenera kukhala kofulumira. Nthawi zambiri, imayimitsidwa mukatembenuza theka la bwalo. Lolani makinawo ayendetse kwakanthawi kuti awone chisanu musanasankhe kuti apitirize kusintha. Dikirani mpaka opareshoniyo ikhale yokhazikika ndipo kuzizira kwa kompresa kutha musanamangitse chivundikiro chomaliza.
Pamitundu yochepera ma kiyubiki metres 15, popeza kulibe valavu yodutsa mpweya wotentha, ngati chisanu ndi chovuta, kukakamiza koyambira kwa chosinthira chosinthira mafani kumatha kukulitsidwa moyenera. Njira yeniyeni ndiyo kupeza choyamba chosinthira, kuchotsa kachidutswa kakang'ono ka nati yosinthira kusintha, ndiyeno gwiritsani ntchito screwdriver mtanda kuti mutembenuze mozungulira. Kusintha konseko kumafunikanso kuchitika pang'onopang'ono. Isintheni theka la bwalo kuti muwone momwe zinthu zilili musanaganize zosintha.
