Qhov sib txawv tseem ceeb ntawm Freon thiab cov tub yees yog Freon yog lub npe lag luam uas hais txog cov khoom lag luam halocarbon, hos cov tub yees hais txog cov khoom siv lossis cov khoom sib tov siv hauv lub tub yees.
Freon yog lub npe lag luam uas feem ntau suav nrog cov tub yees halocarbon uas ua rau ozone depletion. Tsis tas li ntawd, qee qhov Freon tebchaw muaj txiaj ntsig zoo li aerosol propellants. Cov tub yees yog ib qho chaw uas peb siv tshwj xeeb rau cov twj tso kua mis thiab cov tub yees hauv lub tub yees.
Freon yog dab tsi?
Freon yog ib qho aerosol propellant, refrigerant, los yog organic hnyav uas muaj ib los yog ntau tshaj ntawm ib pawg ntawm chlorofluorocarbons thiab lwm yam compounds. Nws yog lub npe lag luam rau ib pawg ntawm halocarbons. Ntxiv mus, cov halocarbons no muaj txiaj ntsig zoo li cov tub yees thiab aerosol propellants. Tus tswv ntawm lub cim lag luam no yog "Lub Tuam Txhab Chemours". Cov tebchaw no ruaj khov, flammable thiab tsis muaj tshuaj lom. Lawv yog gases los yog kua. Ob tug tswv cuab tseem ceeb ntawm pawg no yog chlorofluorocarbons (CFCs) thiab Hydrochlorofluorocarbons (HCFCs), uas cov tuam ntxhab siv los ua cov tub yees.
Daim duab 01: Lub tub yees muaj Freon
Txawm li cas los xij, tsis yog txhua lub tub yees nyob hauv pab pawg ntawm Freon; nws tsuas yog siv rau qee cov tub yees. Qhov tseem ceeb tshaj plaws, kev siv cov tshuaj no tau raug txiav tawm ntawm 20th xyoo pua vim nws cov teebmeem tsis zoo rau txheej txheej ozone
Lub tub yees yog dab tsi?
Cov tub yees yog cov khoom siv lossis cov khoom sib xyaw siv rau tub yees. Nws feem ntau yog kua. Peb tuaj yeem siv lawv hauv cov twj tso kua mis kub thiab cov tub yees. Nyob rau hauv cov voj voog no, cov tub yees ua rau lub sijhawm hloov ntawm cov kua mus rau cov roj thiab lwm yam. Fluorocarbons tau nrov nyob rau hauv lub xyoo pua 20 thxyoo pua raws li cov tub yees ua tau zoo, tab sis kev siv ntawm lawv raug txwv vim tias nws muaj kev phom sij, uas suav nrog ozone depletion. Cov tebchaw uas peb siv niaj hnub no yog ammonia, sulfur dioxide thiab propane (los yog lwm yam uas tsis yog-halogenated hydrocarbons).
Daim duab 02: Cov tub yees sib txawv
Yog tias peb yuav siv cov khoom sib xyaw no hauv lub tub yees, lawv yuav tsum muaj cov khoom siv hluav taws xob uas xav tau: tsis muaj corrosive, nyab xeeb (dawb los ntawm toxicity thiab flammability), tsis muaj kev puas tsuaj rau ozone txheej, tsis ua rau muaj kev hloov pauv huab cua, thiab lwm yam. Ammonia, carbon dioxide thiab lwm yam tub yees uas peb siv niaj hnub no tsis muaj teeb meem rau cov txheej txheem ozone thiab muaj peev xwm ua kom lub ntiaj teb sov tsawg tshaj plaws, yog li tsis muaj kev hloov pauv huab cua phem.
Thaum tshem cov tub yees, peb yuav tsum rov ua dua tshiab txhawm rau tshem tawm cov kab mob uas lawv muaj. Tsis tas li ntawd, peb yuav tsum xav txog qee cov tub yees ua cov khib nyiab pov tseg, txawm tias thaum rov ua dua.
Qhov txawv ntawm Freon thiab tub yees yog dab tsi?
Freon yog ib qho aerosol propellant, refrigerant, los yog cov organic hnyav uas muaj ib los yog ntau tshaj ntawm ib pawg ntawm chlorofluorocarbons thiab lwm yam compounds thaum refrigerant yog ib yam khoom los yog ib tug sib tov siv rau tub yees. Qhov sib txawv tseem ceeb ntawm Freon thiab tub yees yog tias Freon yog lub npe lag luam uas hais txog cov khoom lag luam halocarbon, thaum lub tub yees hais txog cov khoom siv lossis cov khoom sib xyaw siv hauv lub tub yees. Ntxiv mus, cov tswv cuab ntawm pawg Freon feem ntau yog halogenated compounds thaum lub tub yees peb siv tam sim no tsis yog-halogenated compounds.
Freon muaj txiaj ntsig zoo li cov tub yees thiab aerosol propellants thaum cov tub yees siv tau zoo hauv cov twj tso kua mis cua sov thiab lub voj voog tub yees. Piv txwv rau Freon suav nrog chlorofluorocarbons (CFCs) thiab Hydrochlorofluorocarbons (HCFCs) thaum piv txwv rau cov tub yees yog ammonia, sulfur dioxide, carbon dioxide, thiab lwm yam.
Summary – Freon vs Refrigerant
Freon yog lub npe lag luam thaum lub tub yees yog lub npe ntawm ib pab pawg sib txuas siv nyob rau hauv cov twj tso kua mis cua sov thiab lub voj voog tub yees. Qhov sib txawv tseem ceeb ntawm Freon thiab refrigerant yog Freon yog lub npe lag luam uas hais txog cov khoom lag luam halocarbon, hos cov tub yees hais txog cov khoom siv lossis cov khoom sib xyaw siv hauv lub tub yees.
