Emerson webinar muab qhov hloov tshiab ntawm cov qauv tshiab hais txog kev siv A2Ls
Raws li peb nyob ze ntawm lub xyoo ib nrab ntawm lub ntsiab lus, HVACR kev lag luam tab tom saib ze li cov kauj ruam tom ntej hauv lub ntiaj teb theem ntawm hydrofluorocarbon (HFC) cov tub yees tshwm rau ntawm ntug.Cov hom phiaj decarbonization tshwm sim yog tsav kev txo qis hauv kev siv high-GWP HFCs thiab kev hloov mus rau tiam tom ntej, qis-GWP refrigerant lwm txoj kev.
Hauv E360 Webinar tsis ntev los no, Rajan Rajendran, Emerson tus lwm thawj coj thoob ntiaj teb ntawm kev ruaj ntseg, thiab kuv tau muab kev hloov kho tshiab ntawm cov txheej txheem ntawm cov tub yees thiab lawv cov kev cuam tshuam rau peb txoj kev lag luam.Los ntawm tsoomfwv- thiab lub xeev-tus thawj coj theem pib mus rau kev hloov pauv cov qauv kev nyab xeeb tswj kev siv A2L "qis flammability" tub yees, peb tau muab cov ntsiab lus ntawm cov toj roob hauv pes tam sim no thiab sib tham txog cov tswv yim kom ua tiav tam sim no thiab yav tom ntej HFC thiab GWP txo.
AIM ACT
Tej zaum tus tsav tsheb tseem ceeb tshaj plaws nyob rau hauv US HFC phasedown yog xyoo 2020 dhau los ntawm American Innovation thiab Manufacturing (AIM) Txoj Cai thiab txoj cai nws muab rau Lub Chaw Tiv Thaiv Ib puag ncig (EPA).EPA tab tom ua ib lub tswv yim uas txwv tsis pub cov khoom siv thiab kev xav tau ntawm high-GWP HFCs raws li lub sijhawm teem tseg los ntawm Kigali Hloov Kho rau Montreal Protocol.
Thawj kauj ruam tau pib xyoo no nrog kev txo qis 10% hauv kev noj thiab tsim cov HFCs.Cov kauj ruam tom ntej yuav yog 40% txo qis, uas yuav siv tau rau xyoo 2024 - tus qauv ntsuas uas sawv cev rau thawj qhov kev poob qis hauv US HVACR cov haujlwm.Cov tub yees ntau lawm thiab ntshuam quotas yog raws li GWP kev ntsuam xyuas ntawm ib lub tub yees tshwj xeeb, yog li txhawb kev tsim khoom ntawm cov tub yees qis-GWP thiab txo qis ntawm qhov muaj GWP HFCs siab.Yog li ntawd, txoj cai ntawm kev muab khoom thiab kev thov yuav tsav HFC tus nqi thiab ua kom lub zog hloov mus rau qis-GWP xaiv.Raws li peb tau pom, peb txoj kev lag luam twb tau nce HFC tus nqi.
Ntawm qhov xav tau, EPA tab tom thov kom tsav qis GWP HFC kev siv cov cuab yeej tshiab los ntawm kev tso cov tub yees tshiab GWP txwv hauv kev lag luam tub yees thiab kev siv cua txias.Qhov no tuaj yeem ua rau rov qab los ntawm Txoj Cai Tshiab Tseem Ceeb Tshiab (SNAP) txoj cai 20 thiab 21 thiab/lossis kev qhia txog SNAP cov lus pom zoo rau kev pom zoo cov kev xaiv qis-GWP tshiab thaum lawv dhau los siv rau hauv cov tshuab tub yees tshiab.
Txhawm rau pab txiav txim siab seb qhov kev txwv GWP tshiab yuav yog, AIM Act cov neeg txhawb nqa tau thov kev lag luam tawm tswv yim los ntawm kev thov, ntau yam uas EPA twb tau txiav txim siab.Tam sim no EPA tab tom ua haujlwm rau cov ntawv sau tseg ntawm kev txiav txim siab, uas peb cia siab tias yuav pom xyoo no.
EPA lub tswv yim rau kev txwv HFC thov kuj tseem siv tau rau kev pabcuam ntawm cov khoom siv uas twb muaj lawm.Qhov tseem ceeb ntawm qhov kev xav tau sib npaug no feem ntau yog tsom rau kev txo qis, kev txheeb xyuas, thiab kev tshaj tawm (zoo ib yam li EPA's Section 608 cov lus pom zoo, uas tau coj cov tiam dhau los ntawm cov tub yees phasedowns).EPA tab tom ua haujlwm los muab cov ntsiab lus ntsig txog kev tswj hwm HFC, uas tuaj yeem ua rau rov qab los ntawm Tshooj 608 thiab/lossis ib qho kev pabcuam HFC tshiab tag nrho.
HFC PHASEDOWN TOOLBOX
Raws li Rajan tau piav qhia hauv webinar, HFC phasedown thaum kawg yog npaj los txo qis cov pa hluav taws xob (GHG) emissions raws li lawv qhov cuam tshuam ncaj qha thiab tsis ncaj qha rau ib puag ncig.Cov emissions ncaj qha hais txog lub peev xwm rau cov tub yees kom xau lossis tso tawm rau hauv qhov chaw;indirect emissions xa mus rau kev siv lub zog ntawm cov tub yees los yog cov khoom siv cua txias (uas yog kwv yees li 10 npaug ntawm qhov cuam tshuam ncaj qha emissions).
Raws li kev kwv yees los ntawm AHRI, 86% ntawm tag nrho cov tub yees siv tau los ntawm cov tub yees, cua txias, thiab cov khoom siv cua sov.Ntawm qhov ntawd, tsuas yog 40% tuaj yeem raug ntaus nqi los sau cov cuab yeej tshiab, thaum 60% yog siv rau topping tawm cov tshuab uas tau muaj cov khoom xau ncaj qha.
Rajan tau qhia tias kev npaj rau cov kauj ruam tom ntej hloov pauv hauv HFC txo qis hauv 2024 yuav xav kom peb txoj kev lag luam los txhawb cov tswv yim tseem ceeb hauv HFC phasedown toolbox, xws li kev tswj cov tub yees thiab cov cuab yeej tsim cov kev coj ua zoo tshaj plaws.Hauv cov txheej txheem uas twb muaj lawm, qhov no yuav txhais tau tias muaj kev tsom mus rau kev saib xyuas kom txo tau ob qho tib si ncaj qha thiab qhov cuam tshuam ib puag ncig ntawm kev ua haujlwm tsis zoo thiab lub zog ua haujlwm.Cov lus pom zoo rau cov tshuab uas twb muaj lawm muaj xws li:
Tshawb nrhiav, txo, thiab tshem tawm cov dej xau ntawm cov tub yees;
Retrofitting mus rau qis-GWP refrigerant nyob rau hauv tib chav kawm ntawv (A1), nrog rau qhov zoo tshaj plaws-case scenario ntawm xaiv cov khoom uas kuj A2L-npaj;thiab
Rov qab thiab rov qab cov tub yees siv rau hauv kev pabcuam (tsis txhob tso cov tub yees lossis tso rau hauv qhov chaw).
Rau cov cuab yeej tshiab, Rajan pom zoo siv qhov qis tshaj qhov ua tau GWP lwm txoj hauv kev thiab siv cov txheej txheem tub yees tshiab uas siv cov nqi qis dua.Raws li tau ua nrog rau lwm qhov kev xaiv them nqi qis - xws li tus kheej muaj, R-290 systems - lub hom phiaj kawg yog kom ua tiav lub peev xwm siab tshaj plaws uas siv tus nqi tsawg kawg nkaus ntawm cov tub yees.
Rau ob qho tib si tshiab thiab cov khoom siv uas twb muaj lawm, nws yog ib qho tseem ceeb uas yuav tsum muaj txhua yam khoom siv, khoom siv, thiab cov tshuab ua haujlwm raws li kev tsim qauv zoo, suav nrog thaum lub sijhawm teeb tsa, commissioning thiab kev ua haujlwm ib txwm muaj.Ua li no yuav txhim kho lub zog siv hluav taws xob thiab kev ua haujlwm thaum txo qhov cuam tshuam tsis ncaj.Los ntawm kev siv cov tswv yim no ntawm cov cuab yeej tshiab thiab cov uas twb muaj lawm, peb ntseeg tias peb txoj kev lag luam tuaj yeem ua tiav HFC txo qis dua 2024 theem - nrog rau 70% txo tau teem tseg rau 2029.
A2L EMERGENCE
Ua kom tiav qhov xav tau GWP txo qis yuav xav tau kev siv cov tub yees A2L tawm tshiab nrog qhov ntsuas "qis dua".Cov kev xaiv no - kuj tseem yuav yog ntawm cov uas tsis ntev los no tau txais kev pom zoo los ntawm EPA - tau raug hloov kho sai sai ntawm cov qauv kev nyab xeeb thiab cov cai hauv tsev tsim los pab kom lawv siv tau zoo hauv kev lag luam tub yees.Los ntawm qhov pom ntawm cov tub yees duab, Rajan tau piav qhia tias cov tub yees A2L tau tsim thiab piv rau lawv cov HFC cov neeg ua ntej ntawm GWP thiab cov kev ntsuas muaj peev xwm.
