Lub tub yees txias yog dab tsi?
Tub yees yog cov kua hluav taws xob siv nyob rau hauv thermal cycles, thaum ua ke nrog rau ib qho chaw cua txias lossis cua txias - yuav luag txhua yam uas tuaj yeem tswj hwm qhov txias txias (lossis cov pa dej khov kho kom sov)
Cov pawg tseem ceeb ntawm cov tub yees muaj raws li nram no:
Hydrochlorofluorocarbons (HCFC)
HCFC yog qhov sib txuas ntawm hydrogen, chlorine, fluorine, khoom siv HCFC thiab nruab nrab}}}}}}}}}}}}}}}}}}}}}}}} Piv txwv: R241B {5} {5
Hydrofluorocarbons (HFC)
HFC yog kev sib txuam ntawm fluorinated hydrocarbons nrog xoom odp thiab nruab nrab ntawm cov GWP, yog li muab ib qho piv txwv ib puag ncig zoo li cas, yog li muab piv txwv li qub: R32, R134A.
Hydrofluoroolfins (hfo)
HFO yog muaj xws li ntawm hydrogen, fluorine thiab cov roj ntsha atoms txuas los ntawm ib qho kev sib txuas lus ib puag ncig ntawm atom thiab qis Piv txwv: RFO1234YF, HFO1234ZE, Hfo1234YZ .
Tub Yees Xaiv Cov Qauv Xaiv
Tub yees siv roj paub tias yuav luag txhua lub tub yees kev lag luam uas tau ua tiav rau cov tub yees ua tsis tau zoo, cov khoom siv rau cov tub yees, cov khoom siv rau cov tub yees
Ua raws li cov lus qhia ntawm kev ua tsis muaj nplaim taws thiab tsis muaj tshuaj lom
Lwm cov tub yees feem ntau yog azeotropes, tsis-azeotropes lossis nyob ze ntawm cov tshuab hluav taws xob, lossis ntau dua ntawm cov roj nplua nyeem thiab cov khoom siv, cov khoom siv kub, toxicity thiab ruaj khov, thiab lwm yam {{}}
Ob peb HLC (Hydrofluorocarbon) tau dhau los ua lwm txoj kev siv tub yees r} (uas tam sim no} Txawm li cas los xij, HFCs muaj ntau yam teeb meem kev nyab xeeb uas yuav tsum tau sau tseg:
Siab: HFC cov tub yees ua haujlwm ntawm cov kev ntsuas siab thiab tsis tuaj yeem siv ua retrograde tub yees {}}
Cov khoom siv tau: raws li cov ntaub ntawv (xws li cov ntaub ntawv (xws li lub cev muaj zog rwb thaiv tsev) Deteriorate, nws yuav ua rau cov khoom siv hluav taws xob tsis muaj zog
Flammability: Tshuaj xau ntawm cov kua tawg tuaj yeem ua rau hluav taws kub lossis tawg âotropes thiab yuav hloov lawv cov kev xaiv uas yuav tsum tau txiav txim siab.
Lom zem: Qee lub teb chaws tau tshawb nrhiav thiab tau siv cov kev xaiv tshuaj lom neeg ua haujlwm, nws yog qhov tsis muaj kuab heev, ntxiv rau qhov tsis muaj nplaim taws, tus nqi pib (Tlv) rho tawm qhov hnyav nruab nrab (JWA) yuav tsum tsawg dua 400 feem ib lab (PPM) {{5 5}
Tsis tas li ntawd, kev ua tau zoo ntawm kev xaiv cov tub yees yuav tsum zoo ib yam li cov tub yees txias nws hloov .
Lwm cov qauv hais txog cov pa tub yees yuav suav nrog:
Ib qho kev hloov pauv ib txwm hloov chaw ua haujlwm yog maj phaning tawm hcfc tub yees gases
Qhov muaj ntawm lwm txoj kev hloov tub yees
GWP (Ntiaj teb sov sov muaj peev xwm)
ODP (Ozone Depletion Muaj Peev Xwm Muaj Peev Xwm
Muab cov roj nqus haum rau txhua tus neeg xaiv cov tub yees
Cov tub yees siv hauv cov tshuab cua txias li cas?
Tsuas yog muab tso, lub tshuab cua txias muaj peb feem: lub compressor, lub condenser, lub condenser thiab cov evaporator .
Lub tshuab pa hluav taws xob kev kub siab rau cov tub yees hauv cov pa roj hmab los ntawm muaj, nws txav mus rau hauv lub taub hau roj cua sov thiab txav mus rau cov evaporator, uas nws tig rov qab mus rau hauv ib lub siab hnyav roj . Cov txheej txheem no yog conducive rau qhov kub ntxaij, muab cua txias rau hauv chav.
Zhonglian Zog muaj ntau xyoo ntawm kev paub thiab kev ua phooj ywg hauv kev txhawb nqa thiab ua rau cov tub yees kom zoo rau cov tub yees thiab cua txias}
Peb muab cov khoom siv ncaj qha los yog lwm txoj hauv kev uas tau nce qib, thov saib xyuas cov tub yees, thov saib rau peb cov tub yees thiab lawv cov ntawv thov ntau {}}
