Regiriguer, omwe amadziwikanso kuti ndi firiji, ndiye chinthu chogwirira ntchito mu firiji. Pakadali pano, pali mitundu yoposa 80 ya zinthu zomwe zingagwiritsidwe ntchito ngati firiji. Rifirikants Revirijint kwambiri (kuphatikiza: R22, R134A, R407C, R31), RA2), R290, R200a).
Zizindikiro za kusintha kwa mafiriji padziko lonse lapansi zimaphatikizapo: Ozone atayatsidwa bwino (Odp) ndi kutentha kwadziko lapansi (GWP); Kuphatikiza pa zomwe zimakhudza chilengedwe, kuphikanso kuphikanso kungakhale kovomerezeka kuteteza miyoyo ndi katundu wa anthu.
ODP OZONO YOTHANDIZA KUTI: Zikuwonetsa kuthekera kwa chlorofluorbocarbocarbonsare munthawi yomwe ikuwononga ozoni. Zocheperako mtengo, zabwino zachilengedwe za mufiriji. Kuyandikana ndi ODP miyeso yocheperako kapena yofanana ndi 0.05 imawerengedwa zovomerezeka malinga ndi kuchuluka kwapano.
Kutha kwa GWP Nthawi zambiri amawerengera GWP potengera zaka 100, kutanthauzira monga Gwp100, "montreal Protocol" ndi "Kyoto Protocol" onse awiri amagwiritsa ntchito GWP100.
1. Kugawidwa kwa firiji
Malinga ndi GB / T 7778-2017, firiji ya firient imagonjera m'magulu 8, A1, A2, A2, B1L, omwe ali otetezeka kwambiri ndipo B3 ndiowopsa kwambiri.
Magulu otetezeka a Riffints ofanana ndi awa:
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, R407C, R408A, R512, R501, R514A, R744
Lembani A2: R142B, R152A, R406A, R411A, R411B, R412A, R418, R418A, R417
Gulu la A2L: R143a, R32, R1234YEF, R123ZE (E)
Kalasi A3: R290, R600, R600a, R610, R1270, R510, R510a, R511A
Gulu B1: R123, R245FA
Gulu la B2l: R717
Malinga ndi matekitsi oyatsira magazi a EXPORY TS mufiriji pansi pa mizere ya m'mlengalenga (100kPa), itha kugawidwa: Kutentha Kwambiri - kutentha kwapakatikati, komanso firiji yotsika-kutentha.
Kutentha kochepa kwambiri - kutentha kotentha: Kutentha kwapamwamba kumakhala kwakukulu kuposa 0 ° C, ndi kukakamiza kwake kuli kotsika kuposa 29.41995 × 10495Pa. Izi ndi zoyenera kugwiritsidwa ntchito mu firiji ya centrifugal firiji yopanga mpweya.
Miyezo yapakatikati-yopanda kupanikizika: yapakatikati-sing'anga yothandizira kutentha: Kutentha kwa Spapo Mtundu uwu wa firiji nthawi zambiri umagwiritsidwa ntchito mu malingaliro wamba osakanikirana ndi njira ziwiri zophatikizira ku firiji.
Kuthamanga kwambiri komanso kutsika-kutentha kwambiri: Kuthamanga kwambiri komanso kutentha kochepa kwambiri: Kutentha kwa madzi kutsika kuposa -50 ° C, ndipo kupsinjika kufupika ndikokwera kuposa 196.133Pa. Mtundu wamtunduwu ndi woyenera gawo lotsika-kutentha kwa chipangizo cha Cascade kapena chipangizo chotsika-chotsika pansipa -70 c.
