Firigo, uzwi kandi nka firigo, nicyo kintu gikora muri sisitemu yo gukonjesha. Kugeza ubu, hari ubwoko burenga 80 bwibintu bishobora gukoreshwa nka firigo. Abahagaritse cyane ni freon (harimo: R22, R107c, R410A, H2O), Amazi (H290, R6000, R600A).
Ibipimo byerekana ingaruka ku bashoferi ku isi hose harimo: ozone ubushobozi bwo guhungabanya (odp) ndetse n'ubushyuhe bukabije ku isi (GWP); Usibye ingaruka ku bidukikije, abahwari bagomba kandi kugira umutekano byemewe kugirango urinde ubuzima bwabantu n'umutungo.
Ibishoboka bya odp ozone: byerekana ubushobozi bwa chlorofürbocarbone mukirere kugirango isenye urwego rwa ozone. Gitoya agaciro, ibyiza biranga ibidukikije bya firigo. Firigo ifite indangagaciro za ODP munsi cyangwa ingana na 0.05 zifatwa nkukuri ukurikije urwego rugezweho.
GWP ubushyuhe bwisi: Ikimenyetso cyingaruka z'ikirere cyatewe n'ubwikorikori bw'ikirere, byerekana ko mu gihe runaka, harahiwe cyane ku buryo bumwe bwa gazi runaka, CO2 GWP = 1.0. Ubusanzwe kubara GWP bishingiye ku myaka 100, byerekanwe nka GWP100, "protocole ya montoal" na "kyoto protocole" byombi bikoresha gwp100.
1. Gushyira mu bikorwa abaharanira ubukorikori
Nk'uko GB / T 7778-2017, umutekano ushinzwe ubukorikori ugabanijwe mu byiciro 8, aribo: A2L, A2, B3, B3, B3, muri b3 ni bibi cyane.
Urwego rwumutekano wibihano bisanzwe ni ibi bikurikira:
Andika A1: R11, R12, R11, R113, R115, R102a, R436a, R403B, R403B, R407A, R407B, R40S7c, R407D, R408A, R409A, R417A, RON22D, R502, R508B, R508B, R513A, R744
Andika A2: R142B, R152A, R416A, R41YA, R412a, R418B, R418A, R419A, R512a
A2L Icyiciro: R143A, R32, R1234YF, R1234ze (E)
Icyiciro A3: R290, R600, R600A, R601A, R1270, R570, R510A, R511A
Icyiciro B1: R123, R245FA
B2L Icyiciro: R717
Dukurikije ubushyuhe bwo guhinga bwa firigo mu muvuduko rusange w'ikirere (100kpa), birashobora kugabanywamo: Guhagarika ubushyuhe bwinshi, firigo idasanzwe, n'ubushyuhe buke.
Umuvuduko ukabije-ubushyuhe bwinshi: ubushyuhe bwo hejuru burenze 0 ° C, hamwe nigitutu cya condensic kiri munsi ya 29.41995 × 104pa. Aba bashoferi bakwiriye gukoreshwa mudusefatizo za centrifugal muri sisitemu yo guhuza ikirere.
Hagati-umuvuduko-ubushyuhe buciriritse: Umuvuduko-wo hagati-Ubushyuhe-Ubushyuhe -50 ~ 0 ° C, Umuvuduko (196.113 ~ 294PA. Ubu bwoko bwa firigo bukoreshwa muri rusange muburyo busanzwe bwimibare hamwe nibice bibiri bya compression ya piston.
Umuvuduko mwinshi hamwe nubushyuhe buke: Umuvuduko-mwinshi nubushyuhe buke: Ubushyuhe bwo hejuru burenze -50 ° C, hamwe nigitutu cya condensi kiri hejuru ya 196.133 × 104pa. Ubu bwoko bwa firigo bukwiranye nubushyuhe buke-buke bwibikoresho bya finateri ya cascade cyangwa ibikoresho byubushyuhe buke hepfo -70 ° C.
