Ukwenza ifriji, uqonde kuqala ulwazi oluqhelekileyo lwefriji

Ifriji, ekwabizwa ngokuba yifriji, yinto esebenzayo kwinkqubo yokuphucula. Okwangoku, zingaphezulu kweentlobo ezingama-80 zezinto ezinokusetyenziswa njengezerigera. Ezona frierants ezixhaphakileyo ze-freon (kubandakanya: i-R22, i-R13A, R40A, i-AmmonA), i-Ammolbon (i-Amonia (i-HOMONI), i-R390, i-R69A).

Izalathisi zePhantsi zokwenziwa kweendaba kwimo engqongileyo yehlabathi ibandakanya: I-ozone ingabakho Ukongeza kwifuthe kwindalo esingqongileyo, iifriji kufuneka zibe nokhuseleko lwamkelekileyo ukukhusela ubomi babantu kunye nepropathi.

I-ODP Ozone i-Esone Inokubakho: ibonisa ubuchule bee-chlorofluorocarbons kwimozulu yokutshabalalisa ungqimba lwe-ozone. Ixabiso elincinci, elingcono iimpawu zezendalo zefrijini. Iifriji ezinemilinganiselo ye-ODP engaphantsi okanye ilingane ne-0.05 ithathwa njengezithanjisiweyo ngokusekwe kwinqanaba langoku.

I-GWP yeGallow efudumeleyo: Isalathiso sempembelelo yemozulu ebangelwa ukukhutshwa kwegesi eluhlaza, kubonisa ukuba kwixesha elithile (iminyaka engama-20), iminyaka engama-100, i-GWP ye-GWP = 1.0. Ngokwesiqhelola i-GWP esekwe kwiminyaka eli-100, inxibe i-GWP100, "umgaqo weMontreal" kunye ne "Protor Protocol" zombini zisebenzisa i-GWP100.

1. Ukuhlelwa kweefriji

Ngokutsho kwe-GB / T 7778-2017, UKhuseleko lweGradi luhlulwe lubakala kwi-8, eyi-A1, A2, i-A2, i-A2, i-A1 yeyona ikhuselekileyo kwaye i-B3 yeyona ikhuselekileyo.

Amanqanaba okhuseleko kwiifriji eziqhelekileyo zezi zilandelayo:

Type A1: R11, R12, R13, R113, R114, R115, R116, R22, R124, R23, R125, R134a,, R236fa, R218, RC318, R401a, R401b, R402a, R402b, R403a, R403b, R404a, R407a, R407b, I-R407C, i-R408A, R50A, R501, R50, R508A, R508A, R51A, R5144

Chwetheza i-A2: R142B, R152A, R411B, R411b, R4118b, R418A, R4119A, R4119A

Inqanaba le-A2l: R143A, R32, R1234yf, R123ZE (e)

Iklasi A3: R290, i-R600, i-R600A, R601A, R1270, Re1771, R511a, R511a

ICandelo B1: R123, R245A

Inqanaba le-B2L: R717

Ngokutsho kweqondo lokushisa le-Exvaphu i-ts lefriji ephantsi koxinzelelo lwe-themospic oqhelekileyo (i-100KPA), inokuthi yahlulwe ibe yi: I-Erive-Heraiver frientrants, iMeko ePhakathi yeMeyi, kunye nefriji yeqondo eliphantsi.

Uxinzelelo lwexabiso eliphantsi lobushushu: Iqondo lokushisa elingaphezulu liphezulu kune-0 ° C, kunye nengcinezelo ye-propile iphantsi kune-29.41995 × 104pa. Ezi friji zilungele ukusetyenziswa kwiCentrigual Ukutshutshiswa kweentsiba kwiinkqubo zomoya.

I-Preium-Confraimu-Crevium Medium-Medium-Medium-Confraium-Medium Mediantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantrantranti yeqondo: iqondo lokushisa elingaphakathi --50 ~ c, i-C, i-COUGRAMIng yoxinzelelo (19,4195) ~ 104pa. Olu hlobo lwefriji lusetyenziswa ngokubanzi kuxinzelelo lwenqanaba lenqanaba elinye lenqanaba kunye neenkqubo ze-piston zenqanaba le-piston.

Uxinzelelo oluphezulu kunye neRidiyo yeqondo lobushushu: Uxinzelelo oluphezulu kunye neRiveranti ephezulu kunye neqondo lokushisa eliphantsi lingaphantsi kwe-2 ° C, kwaye uxinzelelo lwe-prountences lungaphezulu kowe-196.133 × 104pa. Olu hlobo lweranti lufanelekile kwinxalenye yeqondo elingaphantsi kweqondo le-cascade okanye isixhobo seqondo lobushushu elingezantsi -70 ° C.
