Chinhu chinonyungudutsa chando chimwe chezvinhu zvakakosha mumafiriji nemafiriji. Basa rayo guru nderekudzivirira kuumbwa kwechando nekunyungudutsa chando chakaunganidzwa pama evaporator coils. Dhizaini ye defrost heater tube yakakosha pakuchengetedza mashandiro akajairika emidziyo. Kunyanya, kana mhepo iri mukati mefiriji kana firiji inopfuura nepakati pe evaporator kuti itonhore, hunyoro huri mumhepo hunogona kuungana uye kuomesa zvishoma nezvishoma pamusoro pe evaporator. Kana aya ma frost layers akasabviswa nenguva, anokora zvishoma nezvishoma uye anotadzisa kutenderera zvakanaka kwemhepo inotonhora, nokudaro zvichikanganisa kufanana uye kugadzikana kwekupisa kwemukati memidziyo.
Kuti mafiriji kana mafiriji agare achikwanisa kugara achipa nzvimbo inodziya zvishoma, vagadziri vanowanzoisa sisitimu yekunyungudutsa otomatiki mumidziyo. Chinhu chikuru chesisitimu iyi chinhu chinonyungudutsa chando, chinotanga nenguva dzakatarwa uye chinoendesa huwandu hwakakodzera hwekupisa kumakoiri e evaporator kuti anyungudise chando chakaunganidzwa. Kushanda uku kwekunyungudutsa chando nguva nenguva hakungobatsiri chete kuchengetedza kutenderera kwemhepo mukati memidziyo asiwo kunovandudza zvakanyanya kushanda kwefiriji uye kunoderedza kushandiswa kwesimba.
Nheyo yekunyungudutsa mufiriji - Chii chinonzi firiji inotonhodzwa nemhepo
Chinhu chikuru chefiriji inotonhodzwa nemhepo ndechekuti haina chando. Kusiyana nemafiriji ane masisitimu ekutonhodza, firiji inotonhodzwa nemhepo haina mukati munogara makanyorova, uye chikafu hachina kubatana. Uyezve, firiji inotonhodzwa nemhepo ine mhepo inotonhora inogara ichitenderera, iyo inosefetwa nesystem yekubvisa kunhuhwirira, uye hwema hwemukati huchachengetwa hutsva kwenguva yakareba, pasina "kunhuhwirira kwefiriji" kusingafadzi. Firiji inotonhodzwa nemhepo haisi isina chando; asi, chando chinodzika pa evaporator. Sezvo iri mukati mefiriji, hatigone kuiona zvakananga nesuo refiriji rakavhurika, saka nenzira yekufananidzira inonzi isina chando. Uyezve, nekuti firiji inotonhodzwa nemhepo inogona kunyungudika yoga.
Nheyo yekunyungudutsa firiji inotonhodzwa nemhepo - Nheyo yekushanda yekunyungudutsa firiji inotonhodzwa nemhepo
Mushure mekunge maitiro ekunyungudutsa apera mudenderedzwa rapfuura, nguva yekunyungudutsa inosangana nemutsetse wegrey uye mutsetse weorenji zvakabatana, uye nguva, compressor, uye fan zvese zvinotanga kushanda panguva imwe chete. Nguva yekunyungudutsa yakabatana neheater yekunyungudutsa, asi nekuda kwekudzivirira kukuru kwemukati kwetimer yekunyungudutsa uye kudzivirira kudiki kwemukati kweheater yekunyungudutsa, voltage yakawanda inoshandiswa kune timer yekunyungudutsa, uye heater yekunyungudutsa inogadzira kupisa kushoma. Kana timer yekunyungudutsa necompressor zvikamhanya panguva imwe chete kwemaawa masere, kubatana kwemutsetse wegrey wetimer yekunyungudutsa nemutsetse weorenji zvakabatana. Heater yekunyungudutsa inofambiswa zvakananga nefuse neswitch yekunyungudutsa, uye mota yekunyungudutsa inopfupikiswa neswitch yekudzora tembiricha yekunyungudutsa. Timer yekunyungudutsa inomira kushanda.
Kana chando chanyunguduka chose, kana tembiricha yepamusoro ye evaporator yakwira kusvika 10-16°C, ma contacts e defrost temperature control switch anobviswa kubva ku defrost circuit, uye panguva imwe chete, defrost timer inotanga kushanda. Mushure memaminitsi angangoita mashanu, ma contacts e grey line ne orenji anobatanidzwa zvakare, zvichipedzisa imwe automatic defrosting process. Compressor ne fan zvinotanga kushanda zvakare kuti zviome. Zvadaro, kana tembiricha ye evaporator yaderera kusvika pa reset tembiricha ye defrost temperature control switch, temperature control switch inovharwa kuti ibatanidze defrost heater, ichigadzirira defrosting inotevera.
Zvisinei, kana chinhu chinodziisa che defrost chikatadza kushanda zvakanaka, zvakadai sekukwegura, kutsva, kana kusashanda zvakanaka kwe circuit connections, zvinogona kudzivirira defrost cycle kuti isashande zvakanaka. Nekuda kweizvozvo, chando chiri pa evaporator chinogona kuungana nekukurumidza, chichivhara nzira yemhepo uye zvichiita kuti zviomere michina kuchengetedza tembiricha yakatarwa. Izvi hazvingokanganisi chete kuchengetedza chikafu asiwo zvinoisa kushushikana kwakanyanya pazvinhu zvakakosha zvakaita se compressor, uye zvinogona kutokonzera kukuvara kwemidziyo. Saka, kana ukaona kudzikira kwekushanda kwekutonhodza kwefiriji yako kana firiji, kuungana kwechando kusina kujairika mukati, kana kuwedzera kukuru kwekushandiswa kwesimba, unofanira kutarisa nekukurumidza mamiriro e defrost system.
Kana uchifungidzira kuti chinhu chinodziisa mvura chakakanganisika, zvinokurudzirwa kuti utore matanho anotevera nekukurumidza sezvinobvira: Chekutanga, bvisa simba remuchina kuti uve nechokwadi chekuti wakachengeteka; chechipiri, shandisa multimeter kuti uedze simba rekudzivirira rechinhu chinodziisa kuti uone kana chiri mukati menguva yakatarwa yekushanda; pakupedzisira, kana zvikaonekwa kuti chikamu chacho chakakuvara, unofanirwa kutenga chikamu chitsva chinoenderana nemuenzaniso wekutanga kuti uchitsive. Nekuchengetedza uye kutsiva zvikamu zvisina kunaka nenguva, unogona kuwedzera hupenyu hwekushanda kwefiriji kana firiji uye kuve nechokwadi chekuti inogara iri mumamiriro akanaka ekushanda.
