Mawu oyambira firiji

Ndizosatheka kuti mtundu firiji uzigwira ntchito ndi kutentha kwa madzi pansi pamapeto pake kumachitika chifukwa cha chisanu pa machubu ndi zipsepse. Chisanu chimakhala pakati pa kutentha pakati pa kutentha kuti asamutsidwe kuchokera kumalo ndi firiji, zomwe zimapangitsa kuti muchepetse bwino. Chifukwa chake, opanga zida ayenera kugwiritsa ntchito njira zina zomwe nthawi zosathanirana ndi chisanu, koma osakhala ndi ma croctost kapena mpweya wabwino, womwe udzathedwa mu gawo la Marichi. Komanso zosintha pamayendedwe apamtunduwu owonjezerapo onjezerani gawo lina la zovuta za ogwira ntchito kumunda. Akakhazikitsa moyenera, njira zonse zikwaniritse zotsatira zomwezo kusungunuka chisanu. Ngati kuzungulira kwa defrost sikukhazikitsidwa molondola, zomwe zimapangitsa kuti zisakhale zosakwanira (ndikuchepetsa mu Evaporator Mouncy) imatha kuyambitsa kutentha kwambiri m'malo osefukira mu malo owiritsa, kapena kudula mitengo.
Mwachitsanzo, mtengo wamba wokhala ndi kutentha kwa 34f kumatha kukhala ndi kutentha kwa mpweya pafupifupi 29f ndi kutentha kwa evaporat kwa 22f. Ngakhale uku ndi kugwiritsa ntchito kutentha kwanyengo komwe kutentha kwanyengo kuli pamwamba pa 32f, machubu a Evatorator ndi zipsepse kudzakhala pa kutentha pansi pa 32f, ndikupanga kudzikundikira kwa chisanu. Kutulutsa kwa chipongwe kumadziwika kwambiri pa sing'anga kutentha kwamapulogalamu, ngakhale sizachilendo kuwona defrost defrost kapena magetsi mu mapulogalamu awa.

Kubera kuzungulira kwazungulira kuli monga kumveka; Kuletsa kumachitika chifukwa chongotseka kuzungulira kwa firiji, kupewa firiji kulowa mu Evaporator. Ngakhale wopanga umphaka akhoza kugwira ntchito pansi pa 32f, kutentha kwa mpweya mu malo okwanira 32F. Ndi firiji yoyenda pang'onopang'ono, kulola mpweya mu malo okwanira kuti apitilize kudutsa mu chubu cha Evaporatora / zipsepse kumakweza kutentha kwambiri, kusunthira chisanu. Kuphatikiza apo, kusungunuka kwa mpweya mu malo okhazikika kudzapangitsa kutentha kwa mpweya kuti akweze, kuthandizanso kuthandiza kuzungulira. Pazogwiritsa ntchito komwe kutentha kwa mpweya mu malo owotcha nthawi zambiri kumakhala pamwamba pa 32f, kutanthauza kuti kamtunda wa cycle umakhala njira yothandiza kusungunulira chisanu ndipo ndi njira yofala kwambiri pakusintha kwa kutentha.
Ngati deflost yopondera yozungulira ikayambika, yoyenda mu firiji imaletsedwa kuti isalowe mu njira zotsatirazi: wowongolera muyezo wambirix.

Dziwani kuti mu compressor imodzi yomwe chitsetseko cha defrost timeza chimayambitsa kuzungulira pampu, mzere wamadzimadzi solenoid valavu imapangidwa nthawi yomweyo. Compressor ipitiliza kugwira ntchito, kupondaponda mufiriji kuchokera kudongosolo lotsika ndikulandila madzi. Compresser imachoka pomwe kuthamangitsana kwa kuwombera kumagwera pamtunda wocheperako kuti ukhale wolamulira pang'ono.
Mu kakhosi kambirimbiri, wotchi ya nthawiyo imayenda bwino kupita ku madzi am'madzi solenoid valavu komanso yowonjezera. Izi zimasunga voliyumu ya firiji mu EvaPotor. Kuterera kwapamwamba kumawonjezeka, kuchuluka kwa firiji mu Evaporator kumawonjezeranso kuchuluka kwa kutentha, kumachita ngati kutentha kwa kutentha kuti athandize kukweza kutentha kwamphamvu kwa Evaporator.
Palibenso gwero lina la kutentha kapena mphamvu zofunikira pakubweza. Dongosolo lidzabwereranso ku firiji pokhapokha ngati nthawi kapena kutentha kumafikira. Cholowa chimenecho kwa nthawi ya kutentha kwapakatikati kudzakhala kozungulira 48f kapena mphindi 60 za nthawi. Njirayi imabwerezedwanso mpaka kanayi patsiku kutengera mlandu wowonetsera (kapena W / I EVAPTORT).

Ngakhale zimafala kwambiri pamapulogalamu ochepera, chotetezera chamagetsi chitha kugwiritsidwanso ntchito pamapulogalamu otenthetsera. Pamapulogalamu ochepa matenthedwe, osungirako ozungulira sathandiza omwe amapatsidwa kuti mpweya mu malowo umakhala pansi pa 32F. Chifukwa chake, kuwonjezera pa kuzungulira kwa firiji, gwero lakunja limafunikira kuti akweze kutentha kwa magazi. Njira ya Degrost ndi njira imodzi yowonjezera kutentha kwakunja kuti musungunuke chisanu.
Ndodo imodzi kapena zingapo zolimbana zimayikidwa m'kutali kwa EvaPotor. Pamene chikho cha Spostst Timet chimayambitsa kuzungulira kwa magetsi, zinthu zingapo zidzachitika pang'onopang'ono:
. Gawoli lingathetse mwachindunji mwachindunji mosangalatsa kwa zokopa, kapena zogwirizira za fail ya munthu aliyense wa Epeptorator. Izi zisanjidwe kwa zokongoletsera za Evaporatoratoratoratoratoratoratorator, kulola kutentha komwe kumapangidwa ku Scorerst kukhazikika kwa evapor pamtunda wokha, m'malo mosamutsidwa kumlengalenga komwe kumasindikizidwa ndi mafani.
. Izi zitseka chingwe cha madzi solenoid
. Izi zitha kupereka mphamvu mwachindunji ku mafupa a defrtost ntchito (zing'onozing'ono zazing'ono za Amperage), kapena perekani mphamvu yogwiritsira ntchito coil wa controst contrator. Mawotchi ena atakhala oyang'anira oyang'anira omwe ali ndi malingaliro apamwamba a Amperage omwe amatha kupereka mphamvu mwachindunji pakudya kwa defrost chofuna kutsitsa.

Decrost defrrost imaperekanso chotupa kuposa kuzungulira kwa kuzungulira, ndi nthawi yochepa. Apanso, kuzungulira kwa defrost kumathetsa nthawi kapena kutentha. Pa Demost yochotsa phula pakhoza kukhala nthawi yopuma; Nthawi yochepa yomwe ilola kuti chisanu chosungunuka chichotse pamwamba ndikuyika poto. Kuphatikiza apo, matope a Spaporator amachedwetsa kuyambiranso kwa nthawi yochepa pambuyo poti firiji ya firiji iyamba. Izi ndikuwonetsetsa kuti chinyontho chilichonse chomwe chikupezekabe pa Epaporator sopor sichidzawombedwa mu malo otetezedwa. M'malo mwake, idzazizira ndikukhalabe pamtunda wa epaptora. Kuchedwa kwa fanizo kumachepetsa kuchuluka kwa mpweya wofunda womwe umazunguliridwa mu malo otetezedwa pambuyo pake. Kuchedwa kumatha kuchitika ndi kutentha kwa kutentha (thermostat kapena klixon), kapena nthawi yochedwa.
Njira ya Degrost ndi njira yosavuta yopangira zosintha zomwe siothandiza. Magetsi amagwiritsidwa ntchito, kutentha kumapangidwa ndipo chisanu chimasungunuka kuchokera ku Evaporator. Komabe, poyerekeza ndi deffest defrost defrost, imakhala ndi zinthu zochepa chabe: ngati ndalama zowonjezera, zowonjezera zowonjezera za rods, zomwe zimacheza ndi zowonjezera, limodzi ndi zinthu zowonjezera zomwe zikuyenera kuyenera kuzilingalira. Komanso ndalama zowonjezera zamagetsi zowonjezera ziyenera kutchulidwa. Chofunikira cha gwero lamphamvu lakunja kuyambitsa mphamvu zakunyumba za defrost zimabweretsa chilango champhamvu champhamvu poyerekeza ndi kuzungulira.
Chifukwa chake, ndizomwe zimachokera kuzungulira, mpweya wa DegRost ndi magetsi. Munkhani ya Marichi Tidzawunikanso za Demost defrrrost mwatsatanetsatane.
