Nhazi na mmeghe nke mmiri oyi nke ụlọ ọrụ mmepụta ihe

Dabere na ihe mejupụtara kemịkalụ, enwere ike kewaa refrigerants ụlọ ọrụ n'ime ụdị 5: ihe refrigerants inorganic, freon, refrigerants hydrocarbon juputara, refrigerants hydrocarbon na-adịghị mma, na friji ngwakọta azeotropic. Dị ka nrụgide na-ekpo ọkụ si dị, a pụrụ kewaa refrigerants chiller n'ime ụdị atọ: okpomọkụ dị elu (obere-nrụgide) refrigerants, ọkara okpomọkụ (ọkara-nrụgide) refrigerants, na obere okpomọkụ (elu-nrụgide). Igwe nju oyi a na-ejikarị eme ihe na chillers ụlọ ọrụ bụ amonia, freon, na hydrocarbons.

N'oge mmalite nke mmepe mmepụta ihe, a na-eji R12 na R22 mee ihe n'ọtụtụ ngwa nju oyi nke ụlọ ọrụ. Ikike jụrụ oyi nke R12 dị oke ibu, yana ike ike ya dịkwa elu. Mana R12 mebiri oyi akwa ozone ma amachibidoro ya n'ọtụtụ mba.

A na-eji refrigerant R-134a, R-410a, na R-407c, na nrube isi na nchekwa gburugburu ebe obibi nke mba ụwa. S&A ulo oru chillers :

(1)R-134a (Tetrafluoroethane) friji

R-134a bụ refrigerant zuru ụwa ọnụ nke a na-ejikarị dị ka nnọchi maka R12. Ọ nwere okpomọkụ evaporation nke -26.5ºC ma na-ekerịta ihe ndị yiri thermodynamic na R12. Agbanyeghị, n'adịghị ka R12, R-134a adịghị emerụ oyi akwa ozone. N'ihi nke a, a na-eji ya eme ihe na ikuku ikuku ụgbọ ala, ụlọ ọrụ refrigeration nke azụmahịa na ụlọ ọrụ mmepụta ihe, yana dịka onye na-emepụta ụfụfụ maka ịmepụta ihe mkpuchi plastik siri ike. Enwere ike iji R-134a mepụta friji ndị ọzọ agwakọta, dị ka R404A na R407C. Ngwa ya bụ isi dị ka ihe refrigerant ọzọ na R12 na igwe ikuku ikuku na friji.

(2)R-410a friji

Njirimara anụ ahụ na kemịkalụ: N'okpuru okpomọkụ na nrụgide nkịtị, R-410a bụ chlorine na-enweghị chlorine, fluoroalkane, na-abụghị azeotropic agwakọta refrigerant. Ọ bụ gas liquefied enweghị agba, abịakọrọ nke a na-echekwa n'ime cylinder ígwè. N'iji ike nkwụsị nke ozone (ODP) nke 0, R-410a bụ friji na-emetụta gburugburu ebe obibi nke na-adịghị emerụ oyi akwa ozone.

Main Ngwa: R-410a bụ tumadi ji dị ka nnọchi maka R22 na R502. A maara ya maka ịdị ọcha ya, nsi dị ala, enweghị combustibility, yana ọmarịcha arụmọrụ dị jụụ. N'ihi ya, a na-ejikarị ya eme ihe na ikuku ikuku nke ụlọ, obere ikuku ikuku azụmahịa, na ikuku ikuku nke ụlọ.

(3)R-407C ngwa nju oyi

Njirimara anụ ahụ na kemịkalụ: R-407C bụ fluoroalkane na-enweghị chlorine na-abụghị azeotropic agwakọta refrigerant n'okpuru ọnọdụ okpomọkụ na nrụgide nkịtị. Ọ bụ gas liquefied enweghị agba, abịakọrọ nke a na-echekwa n'ime cylinder ígwè. O nwere ike imebi nke ozone (ODP) nke 0, na-eme ka ọ bụrụkwa friji na-emetụta gburugburu ebe obibi nke na-adịghị emerụ oyi akwa ozone.

Main Ngwa: Dị ka onye na-anọchi R22, R-407C e ji ịdị ọcha ya, ala toxicity, noncombustibility, na magburu onwe jụrụ arụmọrụ, ọtụtụ ebe na-eji ezinụlọ ikuku conditioners na obere na ọkara-sized Central ntụ ntụ.

N'ime oge a nke uto ụlọ ọrụ mmepụta ihe, ichekwa gburugburu ebe obibi aghọwo ihe na-emetụ n'ahụ, na-eme ka "nọpụ iche carbon" bụrụ ihe kacha mkpa. Na nzaghachi maka omume a, S&Onye na-emepụta chiller ụlọ ọrụ mmepụta ihe na-agbasi mbọ ike iji refrigerants na-emekọrịta ihe. Site n'ijikọ ọnụ na-akwalite arụmọrụ ike yana ibelata ihe ọkụkụ, anyị nwere ike ịrụ ọrụ n'ịmepụta "obodo zuru ụwa ọnụ" nke ọdịdị ọdịdị ala mara mma mara.
