Yakanyanya Tembiricha Kudzora kweLaser Systems uye Maindasitiri Zvikumbiro Kubva 2002
Mutauro
Zvichienderana nemakemikari ekuumbwa, maindasitiri anopisa mafiriji anogona kukamurwa kuita zvikamu zvishanu: inorganic compound refrigerants, freon, saturated hydrocarbon refrigerants, unsaturated hydrocarbon refrigerants, uye azeotropic musanganiswa refrigerants. Zvinoenderana nekumanikidza kudzvinyirira, chiller refrigerants inogona kuiswa muzvikamu zvitatu: high-temperature (low-pressure) refrigerants, medium-temperature (medium-pressure) refrigerants, uye low-temperature (high-pressure) refrigerants. Mafiriji anoshandiswa zvakanyanya mumaindasitiri ekupisa ammonia, freon, uye mahydrocarbon.
Muchikamu chekutanga chekusimudzira maindasitiri, R12 neR22 yakashandiswa mune yakawanda maindasitiri mafiriji michina. Iko kutonhora kweR12 kwakakura zvakanyanya, uye kushanda kwayo kwesimba kwakakwira zvakare. Asi R12 yakakonzera kukanganisa kukuru ku ozone layer uye yakarambidzwa munyika dzakawanda.
Refrigerants R-134a, R-410a, uye R-407c, mukuteerana nezvinodiwa nepasi rose zvekuchengetedzwa kwezvakatipoteredza, anoshandiswa S&A industrial chillers:
(1)R-134a (Tetrafluoroethane) Refrigerant
R-134a ifiriji inozivikanwa pasi rose iyo inowanzoshandiswa sekutsiva R12. Iyo ine tembiricha yekubuda kwe -26.5 ° C uye inogovera zvakafanana thermodynamic zvivakwa neR12. Zvisinei, kusiyana neR12, R-134a haina kukuvadza kune ozone layer. Nekuda kweizvi, inoshandiswa zvakanyanya mumotokari maair conditioner, kutengeserana uye maindasitiri mafiriji masisitimu, uye seanopupa mumiriri wekugadzira yakaoma epurasitiki ekuisa zvinhu. R-134a inogonawo kushandiswa kugadzira mamwe mafiriji akasanganiswa, akadai seR404A uye R407C. Chishandiso chayo chikuru ndecheimwe refrigerant kuenda kuR12 mumotokari air conditioners uye firiji firiji.
(2)R-410a Refrigerant
Zvenyama uye Kemikari Properties: Pasi peyakajairika tembiricha uye kumanikidzwa, R-410a ndeye chlorine-isina, fluoroalkane, isiri-azeotropic yakasanganiswa refrigerant. Igasi risina ruvara, rakamanikidzwa rakanyungudutswa rinochengetwa mumasilinda esimbi. Iine Ozone Depletion Potential (ODP) ye0, R-410a ifiriji inoshamwaridzana nenharaunda isingakuvadze ozone layer.
Main Application: R-410a inonyanya kushandiswa sekutsiva R22 uye R502. Iyo inozivikanwa nekuchena kwayo, yakaderera toxicity, isingabatike, uye yakanakisa kutonhora kuita. Nekuda kweizvozvo, inoshandiswa zvakanyanya mumhepo air conditioners, madiki ekutengesa air conditioners, uye epakati mhepo air conditioners.
(3)R-407C Refrigerant
Zvenyama uye Chemical Properties: R-407C ndeye chlorine-isina fluoroalkane isiri-azeotropic yakasanganiswa refrigerant pasi peyakajairika tembiricha uye kumanikidzwa. Igasi risina ruvara, rakamanikidzwa rakanyungudutswa rinochengetwa mumasilinda esimbi. Iine Ozone Depletion Potential (ODP) ye0, ichiita kuti ivewo mufiriji wezvakatipoteredza usingakuvadzi ozone layer.
Main Application: Sekutsiva R22, R-407C inoratidzwa nekuchena kwayo, kuderera kwehuturu, kusapisa, uye kutonhora kwakanyanya, inoshandiswa zvakanyanya mudzimba dzemhepo dzemhepo uye zviduku uye zvepakati zvepakati pemhepo.
Munguva yanhasi yekukura kwemaindasitiri, kuchengetedza kwezvakatipoteredza kwave kunetsa, zvichiita kuti "kusarerekera kwekabhoni" kuve chinhu chekutanga. Mukupindura maitiro aya, S&A industrial chiller mugadziri iri kuedza kushanda nesimba kushandisa eco-friendly refrigents. Nekubatana nekusimudzira kushanda kwesimba uye kuderedza kuburitswa, tinogona kushanda kuti tigadzire "musha wepasi rose" unoratidzwa nemamiriro ekunze akasarudzika.

TEYU S&A Chiller yakavambwa muna 2002 iine makore makumi maviri nemaviri ekugadzira chiller ruzivo, uye ikozvino inozivikanwa seyekutonhora tekinoroji piyona uye akavimbika shamwari muindasitiri yelaser.
