Common Refrigerants
Raws li lub ntiaj teb ua ntau dua ib puag ncig, kev siv tshuaj hauv cov tshuab cua txias thiab cov tub yees tau dhau los ua ib qho kev txhawj xeeb loj. Ib qho ntawm cov teeb meem tseem ceeb yog kev siv cov tub yees, tshwj xeeb tshaj yog cov uas muaj hydrochlorofluorocarbons (HCFCs) thiab hydrofluorocarbons (HFCs), uas muaj teeb meem cuam tshuam rau ib puag ncig thiab ua rau lub depletion ntawm ozone txheej.
R22
R22 yog cov tub yees siv ntau tshaj plaws hauv cov tshuab cua txias, tab sis nws tau raug txiav tawm vim tias nws cuam tshuam rau ib puag ncig.
R410A
R410A yog ib qho kev siv ntau dua uas muaj cov coefficient ntau dua ntawm kev ua tau zoo thiab kev siv hluav taws xob zoo dua li R22. Nws kuj yog non-toxic thiab non-flammable, ua rau nws muaj kev nyab xeeb xaiv.
R32
R32 yog ib lub tub yees tshiab uas tau txais kev muaj koob meej vim tias nws lub peev xwm ua kom lub ntiaj teb qis (GWP) thiab kev ua haujlwm siab zog. Nws kuj yog non-toxic thiab non-flammable, ua rau nws xaiv kev nyab xeeb dua li lwm cov tub yees.
R290
R290, tseem hu ua propane, yog lub ntuj tso tub yees uas muaj GWP qis thiab tsis muaj tshuaj lom. Nws tau siv ntau zaus hauv cov tub yees me me vim nws lub zog ua haujlwm siab thiab tsis tshua muaj kev cuam tshuam rau ib puag ncig.
R600A
R600A, tseem hu ua isobutane, yog lwm cov tub yees ntuj uas muaj GWP qis thiab tsis muaj tshuaj lom. Nws yog feem ntau siv nyob rau hauv tsev tub yees thiab lub freezers vim nws lub zog efficiency thiab tsis tshua muaj kev cuam tshuam rau ib puag ncig.
R717
R717, tseem hu ua ammonia, yog lwm cov tub yees ntuj uas tau siv ntau tshaj ib puas xyoo. Nws muaj tsawg GWP, siab zog efficiency, thiab tsis muaj tshuaj lom. Txawm li cas los xij, nws yuav tsum tau tuav tshwj xeeb vim nws qhov corrosive.
Hauv cov ntsiab lus, txhua lub tub yees muaj nws tus kheej cov khoom tshwj xeeb thiab cov yam ntxwv uas ua rau nws tsim nyog rau kev siv tshwj xeeb. Xaiv lub tub yees kom zoo rau koj cov kev xav tau yog qhov tseem ceeb los txo koj qhov cuam tshuam rau ib puag ncig, txhim kho lub zog ua haujlwm, thiab ua kom koj muaj kev nyab xeeb. Raws li lub ntiaj teb tseem ceeb tshaj qhov kev ruaj ntseg, peb tuaj yeem cia siab tias yuav pom kev txuas ntxiv tshiab thiab kev txhim kho hauv thaj chaw ntawm cov tub yees thiab cov tshuab cua txias.
