Paunenge uchishandisa inotonhora yekuchengetedza inotonhora michina yemhepo, firiji uye nechando inotonhora yekuchengetera kuratidzira makabati, nezvimwewo, pachava nechiitiko chekuumbwa kwechando pane evaporator pamusoro. Nekuda kwechando chando, chiteshi chekuyerera chinova chidiki, mhepo yemhepo inoderera, uye kunyange evaporator ichavharwa zvachose, ichikanganisa zvakanyanya kuyerera kwemhepo. Kana chando chakanyanya kukora, chinoita kuti kutonhora uye kutonhora kwemudziyo wefiriji kuwedzere, kuwedzera mashandisiro emagetsi, uye mamwe mafiriji achashandisa.defrost heater chubhukuti defrost nguva nenguva.
Electrical defrost heater chubhu inzira yekudzikisa chando nekudziisa chando chakasungirirwa pamusoro pemidziyo uchishandisa defrost heater chubhu yakarongwa mukati memidziyo. Rudzi urwu rwe defrost heater chubhu imhando yesimbi chubhu-yakaita electric heat element, inonziwo defrosting heat chubhu kana defrost heater chubhu. Iyo yemagetsi defrost heater chubhu chinhu chemagetsi chekudziya umo iyo chubhu yesimbi inoshanda segoko, iyo alloy yekudziya waya sechinhu chekudziya, uye yekupedzisira terminals (waya) inopihwa. Iyo insulating medium ye magnesium oxide poda yakazadzwa zvakanyanyisa muchubhu yesimbi kugadzirisa iyo yekudziya.
Nekuda kwehunhu hwemidziyo yekuchengetera inotonhora, senge hunyoro hwepamusoro uye tembiricha yakadzika mukati memba, kutonhora kunogara kuchitonhora uye kunopisa kuvhunduka,defrosting kudziyisa machubhuanowanzo akavakirwa pachubhu-yakaumbwa emagetsi ekudziya zvinhu, achishandisa yepamusoro-mhando yakagadziridzwa magnesium oxide sekuzadza uye simbi isina tsvina segoko. Mushure mekuderera, iyo yekupedzisira yekubatanidza yakavharwa neakakosha rabha yakatsikirirwa mold, kuitira kuti magetsi ekupisa chubhu inogona kushandiswa kazhinji mumidziyo yekuchengetedza inotonhora. Inogona kukotama mune chero chimiro zvinoenderana nezvinodiwa nemushandisi uye zviri nyore kunyudzwa mukati membabvu yemuchina wemhepo inotonhora kana pamusoro peiyo evaporator yeinotonhora kabati kana pasi pedhiraini tireyi, nezvimwe zvekudzikisa. Iyo yakakosha chimiro chedefrost heaterzviri sezvinotevera:
a) Lead rod (line) : yakabatana neinodziya muviri, yezvikamu uye magetsi ekupa, zvikamu uye zvikamu zvakabatana nesimbi conductive zvikamu.
b) Shell pombi: kazhinji 304 simbi isina tsvina, yakanaka corrosion resistance.
c) Waya yekudziya yemukati: nickel chromium alloy resistance wire, kana iron chromium aluminium wire material.
d) Iyo yemagetsi kupisa pombi chiteshi yakavharwa nesilicone rubber.
Nekubatanidzwa kwepombi yekupisa, nzira yekubatanidza yedefrosting yemagetsi kudziyisa pombiinoratidza kuti Y mubatanidzwa wakaita senyenyedzi, Y inofanira kubatanidzwa kumutsara wepakati, uye ayo asina kuratidzwa ndiwo anobatana nettatu. Semuyenzaniso, defrost heater chubhu yechiller inowanzoita 220V, uye imwe magumo ega ega defrost hita chubhu yakabatana netambo yemoto, uye imwe magumo inobatana neyakarerekera mutsara. Pamusoro pezvo, simba rekuisa rakanyorwa paimba yechubhu yekudziya kazhinji isimba rakayerwa rechubhu yekudziya.
Iyo yemagetsi defrosting nzira iri nyore uye iri nyore kushanda, asi simba redefrosting heat tubekazhinji yakakura, uye kana kunaka kwechubhu yekudziya isina kunaka kana kushandiswa kwenguva yakareba, zviri nyore kupisa kana kukonzera moto, saka nzira yekubvisa magetsi ine njodzi dzakakomba dzekuchengetedza uye inoda kuongororwa nguva nenguva. . Iyo defrost heater chubhu inowanzotarisana nekukuvara kunotevera:
1. Kubva pakuonekwa, zvinogona kuonekwa kuti tsvimbo inotungamirira yakakuvadzwa, simbi yepamusoro yesimbi yakasvibiswa, iyo insulator inokuvadza kana chisimbiso chinokundikana.
2, izvo zvemuviri uye zvemakemikari zvimiro zvechubhu yekudziya zvachinja uye hazvigone kusangana nezvinodiwa zvekushandisa. Semuenzaniso, imwe yeanotevera mamiriro haichagone kushandiswa:
① Iyo yekupokana voltage yechubhu yekudziya yakaderera pane yakajairwa kukosha, iyo yekuvuza yazvino kukosha yakakura kupfuura 5mA kana kukosha kwekudzivirira kwekudzivirira kuri pasi pe1MΩ.
(2) Goko rine murazvo unobuda uye zvinhu zvakanyungudutswa, uye pamusoro pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pacho pakakoromoka.
③ Simba chairo rekudziya chubhu rinopfuura simba rakayerwa ne ± 10%.
④ Chimiro chechubhu chekudziya chakashandurwa zvakanyanya, zvichikonzera kuwanda kwechidzitiro chekudzivirira zviri pachena kusaenzana, uye mashandiro ekudzivirira akanyanya kuderedzwa nekuyera, izvo zvisingaenderane nezviyero zvinoenderana.
