Intangiriro yuburyo bwa firigo

Ntabwo byanze bikunze sisitemu yo gukonjesha ikora hamwe nubushyuhe bwuzuye bwuzuye munsi yubukonje amaherezo bizagira ubukonje bwubukonje kumuyoboro wumuyaga. Ubukonje bukora nka insuliranteri hagati yubushyuhe bwo kwimurwa buva mu kirere na firigo, bigatuma igabanuka ryimikorere ya moteri. Kubwibyo, abakora ibikoresho bagomba gukoresha tekiniki zimwe na zimwe kugirango bakureho ubukonje buri gihe hejuru yubushyuhe.Uburyo bwa defrost burashobora kubamo, ariko ntibugarukira gusa kuri cycle cyangwa defrost de air, amashanyarazi na gaze (bizakemurwa mugice cya II mukibazo cya Werurwe). Na none, guhindura kuriyi gahunda yibanze ya defrost yongeraho urundi rwego rugoye kubakozi ba serivisi. Iyo ushyizeho neza, uburyo bwose buzagera kubisubizo byifuzwa byo gushonga ubukonje. Niba inzitizi ya defrost idashyizweho neza, ibisubizo bituzuye bituzuye (no kugabanya imikorere ya moteri) birashobora gutera ubushyuhe burenze ubushyuhe bwifuzwa mumwanya wa firigo, imyuzure ya firigo cyangwa ibibazo byo gutema amavuta.
Kurugero, isanzwe yerekana inyama igumana ubushyuhe bwibicuruzwa bya 34F irashobora gusohora ubushyuhe bwikirere bwa 29F hamwe nubushyuhe bwuzuye bwa 22F. Nubwo ubu aribwo buryo bwo gukoresha ubushyuhe buringaniye aho ubushyuhe bwibicuruzwa buri hejuru ya 32F, imiyoboro yumuyaga hamwe nudusimba bizaba ku bushyuhe buri munsi ya 32F, bityo bigatuma habaho ubukonje bwinshi. Off cycle defrost ikunze kugaragara kubushyuhe bwo hagati, icyakora ntibisanzwe kubona gazi ya gazi cyangwa amashanyarazi muri izi porogaramu.

CYANE CYCLE DEFROST
Off off cycle defrost ni nkaho byumvikana; defrosting ikorwa no kuzimya gusa inzitizi ya firigo, ikabuza firigo kwinjira mumashanyarazi. Nubwo impemu zishobora kuba ziri munsi ya 32F, ubushyuhe bwikirere mumwanya wa firigo buri hejuru ya 32F. Hamwe na firigo yazungurutse, bituma umwuka uri mumwanya wa firigo ukomeza kuzenguruka unyuze mumashanyarazi / fins bizamura ubushyuhe bwikirere, ushonga ubukonje. Byongeye kandi, umwuka usanzwe winjira mumwanya wa firigo bizatera ubushyuhe bwikirere kuzamuka, bikarushaho gufasha mukuzunguruka. Mubisabwa aho ubushyuhe bwikirere mumwanya wa firigo busanzwe buri hejuru ya 32F, off cycle defrost yerekana ko aribwo buryo bwiza bwo gushonga ubukonje kandi nuburyo bukunze kugaragara bwa defrost mubushyuhe bwo hagati.
Iyo disiketi ya off cycle yatangijwe, gutembera kwa firigo birabujijwe kwinjira mumashanyarazi ukoresheje bumwe muburyo bukurikira: koresha isaha yigihe cya defrost kugirango uzenguruke compressor (igice kimwe cya compressor), cyangwa uzenguruke kumurongo wa sisitemu yumurongo wa solenoid valve utangiza pompe-down (unit compressor unit or complex compressor rack).

Menya ko muri progaramu imwe ya compressor imwe aho isaha ya defrost itangira pomp-down cycle, umurongo wamazi solenoid valve ihita de-ingufu. Compressor izakomeza gukora, ivoma firigo muri sisitemu yo hasi no mubakira amazi. Compressor izunguruka mugihe umuvuduko wo guswera uguye kumurongo wateganijwe kugirango ugabanye umuvuduko muke.
Muri complexor compressor rack, isaha yisaha izenguruka amashanyarazi kumurongo wamazi solenoid valve hamwe nubushakashatsi bwokunywa. Ibi bigumana ingano ya firigo muri moteri. Mugihe ubushyuhe bwa moteri bugenda bwiyongera, ingano ya firigo muri moteri nayo igenda yiyongera mubushyuhe, ikora nk'icyuma gishyuha kugirango ifashe kuzamura ubushyuhe bwubuso bwa moteri.
Nta yandi masoko yubushyuhe cyangwa ingufu arakenewe kugirango habeho defrost cycle. Sisitemu izagaruka muburyo bwa firigo nyuma yigihe cyangwa ubushyuhe bugeze. Urwo rugabano rwo gukoresha ubushyuhe buciriritse ruzaba hafi 48F cyangwa iminota 60 yo kuruhuka. Ubu buryo busubirwamo inshuro enye kumunsi bitewe nurugero rwerekanwe (cyangwa W / I evaporator) ibyifuzo byabakora.

AMATORA
Nubwo bikunze kugaragara kubushyuhe buke, defrost yamashanyarazi irashobora no gukoreshwa mubushyuhe bwo hagati. Kubushyuhe buke buke, off cycle defrost ntabwo ari ngirakamaro bitewe nuko umwuka uri mumwanya wa firigo uri munsi ya 32F. Kubwibyo, usibye kuzimya inzitizi ya firigo, harasabwa isoko yubushyuhe bwo hanze kugirango ubushyuhe bwuka. Amashanyarazi ya defrost nuburyo bumwe bwo kongeramo isoko yubushyuhe bwo hanze kugirango ushonge ubukonje bwubukonje.
Inkoni imwe cyangwa nyinshi zo gushyushya zishyirwa muburebure bwa moteri. Iyo isaha ya defrost itangiye amashanyarazi yumuriro, ibintu byinshi bizabera icyarimwe:
. Uyu muzunguruko urashobora guha imbaraga moteri yumuyaga uhumeka, cyangwa ibifuniko bifata ibyuma bifata moteri ya moteri. Ibi bizazenguruka moteri ya moteri yumuyaga, bizemerera ubushyuhe buturuka kumashanyarazi ya defrost kwibanda kumurongo wa moteri gusa, aho kwimurirwa mumyuka yazengurutswe nabafana.
. Ibi bizafunga umurongo wamazi solenoid valve (hamwe nogukoresha suction niba ikoreshwa), bikarinda gutembera kwa firigo kumashanyarazi.
(3) Ubusanzwe gufungura ifunguye mugihe cya defrost isaha izafunga. Ibi bizatanga ingufu zumuriro wa defrost (progaramu ntoya ya amperage defrost ashyushya porogaramu), cyangwa gutanga ingufu kumashanyarazi afata umushinga wa defrost. Igihe runaka amasaha yubatswe mubahuza bafite amanota menshi ya amperage ashoboye gutanga ingufu zumuriro wa defrost, bikuraho gukenera umushyitsi wihariye wa defrost.

Igishushanyo cya 3 Gishyushya amashanyarazi, guhagarika defrost no gutinda kwabafana

Amashanyarazi ya defrost atanga defrost nziza kuruta kuzenguruka, hamwe nigihe gito. Ubundi na none, defrost cycle izarangira mugihe cyangwa ubushyuhe. Iyo defrost irangiye hashobora kubaho gutonyanga igihe; igihe gito kizemerera ubukonje bwashonze gutemba hejuru yumwuka no mumasafuriya. Byongeye kandi, moteri yabafana ba moteri izatinda gutangira mugihe gito nyuma yigihe cya firigo itangiye. Ibi ni ukugirango umenye neza ko ubuhehere ubwo aribwo bwose bugaragara hejuru yubushyuhe butazatwarwa mumwanya wa firigo. Ahubwo, izahagarara kandi igume hejuru yumwuka. Gutinda kw'abafana kandi bigabanya urugero rw'umwuka ushyushye ukwirakwizwa mu mwanya wa firigo nyuma ya defrost irangiye. Gutinda kwabafana birashobora kugerwaho haba kugenzura ubushyuhe (thermostat cyangwa klixon), cyangwa gutinda kumwanya.
Amashanyarazi ya defrost nuburyo bworoshye bwo guhinduranya porogaramu aho off cycle idafatika. Amashanyarazi arakoreshwa, ubushyuhe buraremwa kandi ubukonje bushonga buva mumashanyarazi. Ariko, ugereranije na off defrost cycle, defrost yamashanyarazi ifite ibintu bike bibi kuri yo: nkigiciro cyigihe kimwe, hiyongereyeho ikiguzi cyambere cyibikoresho bishyushya, abahuza abandi, relay hamwe nubukererwe bwihuse, hamwe nakazi kiyongereye hamwe nibikoresho bikenerwa mugukoresha insinga bigomba gutekerezwa. Ikindi, amafaranga akomeje gukoreshwa mumashanyarazi yinyongera agomba kuvugwa. Ibisabwa byingufu zituruka hanze kugirango zongere ingufu za defrost zivamo ibihano bitanga ingufu mugihe ugereranije na cycle.
Rero, ibyo nibyokuzenguruka, guhumeka ikirere hamwe nuburyo bwo gukuramo amashanyarazi. Mu nomero yo muri Werurwe tuzasubiramo birambuye defrost.
