Refrigerant, inozivikanwawo serefrigerant, ndiyo chinhu chinoshanda mufiriji. Parizvino, kune marudzi anopfuura makumi masere ezvinhu zvinogona kushandiswa serefrigerant. Refrigerant dzinonyanya kushandiswa ndiFreon (kusanganisira: R22, R134a, R407c, R410a, R32, nezvimwewo), ammonia (NH3), mvura (H2O), carbon dioxide (CO2), huwandu hushoma hwehydrocarbons (senge: R290, R600a).
Zviratidzo zvemafiriji pamamiriro ekunze epasi rose zvinosanganisira: kugona kwekubvisa ozone (ODP) uye kugona kwekupisa kwepasi rose (GWP); pamusoro pekukanganisa kwezvakatipoteredza, mafiriji anofanirawo kuva nekuchengetedzwa kunogamuchirika kuchengetedza hupenyu hwevanhu nepfuma yavo.
ODP Ozone Depletion Potential: Inoratidza kugona kwema chlorofluorocarbons ari mumhepo kuparadza ozone layer. Kana kukosha kwacho kukaderera, zvinoita kuti zvakatipoteredza zvive nani. Mafiriji ane ODP values ari pasi kana kuti akaenzana ne0.05 anoonekwa seanogamuchirwa zvichienderana nemazinga aripo iye zvino.
Kugona Kupisa Kwepasi Pose kweGWP: Chiratidzo chemhedzisiro yemamiriro ekunze inokonzerwa nekuburitswa kwemagasi egreenhouse, zvichiratidza kuti mukati menguva yakati (makore makumi maviri, makore zana, makore mazana mashanu), mhedzisiro yegreenhouse yegasi regreenhouse inoenderana nemhando yeCO2 ine mhedzisiro imwechete, CO2. GWP=1.0. Kazhinji verenga GWP zvichibva pamakore zana, anoratidzwa seGWP100, "Montreal Protocol" ne "Kyoto Protocol" ese anoshandisa GWP100.
1. Kupatsanurwa kwemafiriji
Sekureva kweGB/T 7778-2017, kuchengetedzeka kwemufiriji kwakakamurwa kuita zvikamu zvisere, zvinoti: A1, A2L, A2, A3, B1, B2L, B2, B3, pakati pazvo A1 ndiyo yakachengeteka uye B3 ndiyo ine njodzi huru.
Mazinga ekuchengetedza emafiriji akajairika ndeaya anotevera:
Rudzi 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, R407d, R408a, R409a, R410a, R417a, R422d, R500, R501, R502, R507a, R508a, R508b, R509a, R513a, R744
Type A2: R142b, R152a, R406a, R411a, R411b, R412a, R413a, R415b, R418a, R419a, R512a
A2L chikamu: R143a, R32, R1234yf, R1234ze(E)
Kirasi A3: R290, R600, R600a, R601a, R1270, RE170, R510a, R511a
Chikamu B1: R123, R245fa
Chikamu cheB2L: R717
Zvichienderana nekupisa kwemvura inotonhorera pasi pekumanikidzwa kwemhepo kwakajairwa (100kPa), inogona kukamurwa kuita: firiji inotonhorera yepamusoro, firiji inotonhorera iri pakati nepakati, uye firiji inotonhorera iri pasi.
Refrigerant ine simba shoma pakupisa kwakanyanya: tembiricha yekubuda kwemvura yakakwira kupfuura 0°C, uye simba rekudzika kwemvura rakaderera pane 29.41995×104Pa. Mafiriji aya akakodzera kushandiswa mumacompressor erefrigerant ecentrifugal muma air conditioner systems.
Refrigerant yepakati nepakati inomanikidzwa: refrigerant yepakati nepakati inomanikidzwa: tembiricha yemvura inobuda -50 ~ 0°C, kumanikidzwa kwekudziisa (196.113 ~ 29.41995) × 104Pa. Rudzi urwu rwerefrigerant runowanzo shandiswa muzvirongwa zvekupisa zvepiston zvechinguvana uye zvechinguvana.
Refrigerant ine kumanikidzwa kwakanyanya uye tembiricha yakaderera: refrigerant ine kumanikidzwa kwakanyanya uye tembiricha yakaderera: tembiricha yekubuda kwemvura yakaderera pane -50°C, uye kumanikidzwa kwekudziya kwemvura kwakakwira kupfuura 196.133×104Pa. Rudzi urwu rwerefrigerant rwakakodzera chikamu chekupisa kwakaderera chemuchina wekutonhodza wecascade kana muchina wekupisa kwakaderera pasi pe -70°C.
