Sisitemu ya firigo ikoreshwa firigo nk'amazi y'akazi, kandi firigo muri rusange ifite impapuro ebyiri: amazi na gaze. Uyu munsi tuzavuga ku bumenyi bujyanye na firigo.
1. Ni gaze ya firigo cyangwa gaze?
Abashinzwe ubukorikori barashobora kugabanywamo 3: abashinzwe ubukonje bumwe, abatari Azeotropique barokowe, na Azeotropique ikomoka muri Azeotropique.
Ibigize Ibikorwa bimwe bya fincorne ntabwo bizahinduka niba ari gaze ya gaze cyangwa amazi, bityo leta ya gaze irashobora kwishyurwa mugihe ushinja firigo.
Nubwo ibigize firigo ya Azeotropic itandukanye, kubera ko ingingo itetse ari imwe, ibigize gaze n'amazi nabyo nabyo, bityo gaze irashobora kwishyurwa;
Kubera ingingo zitandukanye zitetse za firigo zitari muri Azeotropic, abaharanira amazi n'amazi n'abashoferi ba gase batandukanye mu guhimba. Niba abashoferi ba gaze bongerewe muriki gihe, ibigize abahatanira bayongereye bizaba bitandukanye. Kurugero, gusa firigo imwe ya gaze yongeyeho. Firigo, niko amazi yongeyeho.
Ibyo ni ukuvuga, abahwanye badafite Azeotropic bagomba kongerwaho n'amazi, kandi abadayiro batari Azeotropic bose batangirana na R4. Ubu bwoko bwamazi yongeyeho. Abahwanyo basanzwe badasanzwe ni: R40, R403b, R404a, R407B, R407c, R407A, R410A, R41A.
Naho abandi bashoferi basanzwe, nka: R134a, R22, R290, R290, R600, R600A, IHURIRO RY'IMIKORESHEREZE NTIBIZASUBIZO.
Iyo wongeyeho firigo, dukwiye kwitondera ibi bikurikira:
(1) Itegereze ibibyimba mu kirahure;
(2) Gupima igitutu kinini kandi gito;
(3) gupima compressor igezweho;
(4) Gupima inshinge.
Byongeye kandi, twakagombye kwitonderwa no gushimangirwa ko:
Abahwannye batari Azeotropic bagomba kongerwaho muburyo bwamazi. Kurugero, R410A Frierigent, Ibigize Ibigize Ibi bikurikira:
R32 (Grouromethane): 50%;
R125 (Pentafluoroethane): 50%;
Kubera ko ingingo zishushanya za R32 na R125 ziratandukanye, mugihe Cylinder ya firigo ya R410A isigaye ihagaze neza muri silinder ya firigo ya firigo. R32 iri hasi, birashoboka cyane ko igice cyo hejuru cya firigo nikigize R32.
Kubwibyo, niba firigo ya gaze yongeyeho, firigo yongeyeho ntabwo r410a, ariko r32.
Icya kabiri, ibibazo bisanzwe bya firigo ya firigo
1. Kwimuka kwa fileji
Kwimuka kwa firigo bivuga kwegeranya amafaranga ya firigo muri compressor crankcacase mugihe compressor ifunze. Igihe cyose ubushyuhe imbere muri compressor bukonje kuruta ubushyuhe imbere ya serivise, itandukaniro ryumutungo hagati ya compressor hamwe nuwuhumeka bizatwara firigo ahantu hakonje. Iki kintu gishobora kubaho cyane mubembeye. Ariko, kubitekerezo byinjangwe no gushyushya, mugihe igice cya condensi kiri kure ya compressor, kwimuka bishobora kubaho nubwo ubushyuhe ari hejuru.
Sisitemu imaze gufungwa, niba idahinduwe mumasaha make, niyo nta tandukaniro ryungutu, ibintu byimuka bishobora kubaho bitewe no gukurura firigo muri Crankcase kuri firigo.
Niba firigo irenze urugero yimuka muri crankcase ya coranksor, ibintu bikabije byamazi bizabera mugihe compressor yananiwe, yangiza ibiryo bikanamyambaro, byangiritse bitwikiriye amavuta).
2. Firigo ya firigo yuzuye
