GWP, ODP thiab Atmospheric Lifetime of Refrigerants
Cov tub yees
HVAC, tub yees thiab cua txias yog feem ntau siv nyob rau hauv ntau lub nroog, tsev neeg thiab tsheb.Cov tub yees thiab cua txias muaj feem ntau ntawm cov khoom siv hauv tsev.Tus naj npawb ntawm cov tub yees thiab cua txias hauv lub ntiaj teb yog tus lej loj.Qhov laj thawj yog vim li cas cov tub yees thiab cov cua txias tuaj yeem ua kom txias yog vim qhov tseem ceeb ntawm lub tshuab compressor.Lub compressor siv cov tub yees los thauj cov cua sov thaum ua haujlwm.Cov tub yees muaj ntau hom.Qee cov khoom siv tub yees siv txij li ntev tau ua rau ozone txheej tus phooj ywg thiab cuam tshuam rau lub ntiaj teb sov.Yog li, tsoomfwv thiab cov koom haum tswj hwm kev siv cov tub yees sib txawv.
Montreal raws tu qauv
Montreal raws tu qauv yog daim ntawv cog lus thoob ntiaj teb los tiv thaiv lub ntiaj teb txheej ozone los ntawm phasing tawm cov tshuaj uas deplete nws.Xyoo 2007, Qhov Kev Txiav Txim nto moo XIX/6, tau coj los rau xyoo 2007, los kho cov txheej txheem kom ceev cov theem tawm ntawm Hydrochlorofluorocarbons lossis HCFCs.Cov kev sib tham tam sim no ntawm Montreal Protocol muaj peev xwm raug hloov kho kom yooj yim rau theem qis ntawm hydrofluorocarbons lossis HFCs.
GWP
Lub Ntiaj Teb Warming Potential, los yog GWP, yog ib qho kev ntsuas ntawm kev puas tsuaj rau huab cua phem npaum li cas.GWP ntawm ib qho roj yog hais txog tag nrho cov kev pab cuam rau lub ntiaj teb sov sov uas tshwm sim los ntawm emission ntawm ib chav tsev ntawm cov roj uas txheeb ze rau ib chav tsev ntawm cov pa siv, CO2, uas yog muab ib tug nqi ntawm 1. GWPs kuj yuav siv tau los txhais cov ntsiab lus. cuam tshuam lub tsev cog khoom gases yuav muaj nyob rau hauv lub ntiaj teb no warming lub sij hawm sib txawv los yog lub sij hawm horizons.Cov no feem ntau yog 20 xyoo, 100 xyoo, thiab 500 xyoo.Lub sijhawm horizon ntawm 100 xyoo yog siv los ntawm regulators.Ntawm no peb siv lub sij hawm qab ntug ntawm 100 xyoo nyob rau hauv daim ntawv nram qab no.
ODP
Ozone Depletion Potential, los yog ODP, yog ib qho kev ntsuas ntawm kev puas tsuaj ntau npaum li cas cov tshuaj tuaj yeem ua rau cov txheej txheem ozone piv nrog cov khoom sib xws ntawm trichlorofluoromethane (CFC-11).CFC-11, nrog rau ozone depleting peev xwm ntawm 1.0, yog siv los ua lub hauv paus daim duab rau ntsuas ozone depleting peev xwm.
Atmospheric Lub Neej
Lub neej atmospheric lifetime ntawm ib hom ntsuas lub sij hawm yuav tsum tau los kho qhov sib npaug ntawm cov huab cua tom qab ib tug sai li sai tau nce los yog txo nyob rau hauv concentration ntawm cov tsiaj nyob rau hauv nqe lus nug nyob rau hauv cov huab cua.
Ntawm no yog ib daim ntawv qhia los qhia cov tub yees sib txawv 'GWP, ODP thiab Atmospheric Lifetime.
