Maupangiri atsopano a US Department of Energy's (DOE's), omwe akufotokozedwa kuti "muyezo waukulu kwambiri wopulumutsa mphamvu m'mbiri," akhudza makampani opanga kutentha ndi kuziziritsa.

Miyezo yatsopanoyi, yomwe idalengezedwa mu 2015, ikuyenera kuyamba kugwira ntchito pa Januware 1, 2018 ndipo idzasintha momwe opanga amapangira ma air conditioners padenga, mapampu otentha ndi mpweya wofunda kwa nyumba "zotsika".monga masitolo ogulitsa, malo ophunzirira ndi zipatala zapakati.

Chifukwa chiyani?Cholinga cha muyezo watsopano ndikuwongolera magwiridwe antchito a RTU ndikuchepetsa kugwiritsa ntchito mphamvu ndikuwononga.Zikuyembekezeka kuti zosinthazi zipulumutsa eni malo ndalama zambiri pakapita nthawi—koma, zowonadi, zomwe 2018 zikupereka zikupereka zovuta kwa okhudzidwa pamakampani onse a HVAC.

Tiyeni tiwone madera ena omwe makampani a HVAC angakhudzidwe ndi kusinthaku:

Zomangamanga / kamangidwe - Omangamanga adzafunika kusintha mapulani apansi ndi zitsanzo zamapangidwe kuti akwaniritse miyezo yatsopano.

Ma code adzasiyana malinga ndi mayiko - Geography, nyengo, malamulo apano, ndi malo ozungulira zonse zidzakhudza momwe dziko lililonse limatengera ma code.

Kuchepetsedwa kwa mpweya ndi mpweya wa carbon - The DOE ikuyerekeza kuti miyezo idzachepetsa kuwononga mpweya ndi matani 885 miliyoni.

Eni nyumba akuyenera kukweza - Ndalama zam'tsogolo zidzachepetsedwa ndi $ 3,700 posungira pa RTU pamene mwiniwake alowetsa kapena kubwezeretsa zida zakale.

Zitsanzo zatsopano sizingawonekere zofanana - Kupita patsogolo kwa mphamvu zamagetsi kumabweretsa mapangidwe atsopano mu RTUs.

Kuwonjezeka kwa malonda a HVAC makontrakitala / ogawa - Makontrakitala ndi ogulitsa angayembekezere kuwonjezeka kwa 45 peresenti ya malonda mwa kubwezeretsanso kapena kukhazikitsa ma RTU atsopano pa nyumba zamalonda.

Bizinesiyo, malinga ndi mbiri yake, ikupita patsogolo.Tiyeni tione mmene tingachitire.

Dongosolo Lamagawo Awiri kwa Opanga HVAC

DOE ipereka miyezo yatsopano mu magawo awiri.Gawo Loyamba likuyang'ana pa kuwonjezeka kwa mphamvu zamagetsi mu ma RTU onse a air conditioning ndi 10 peresenti kuyambira January 1, 2018. Gawo Lachiwiri, lokonzekera 2023, lidzasokoneza kuwonjezeka kwa 30 peresenti ndikuphatikizanso ng'anjo zotentha.

Bungwe la DOE likuyerekeza kuti kukweza mipiringidzo pakuchita bwino kudzachepetsa kugwiritsa ntchito kutentha ndi kuziziritsa malonda ndi 1.7 thililiyoni kWh pazaka makumi atatu zikubwerazi.Kuchepetsa kwakukulu kwa kugwiritsa ntchito mphamvu kubweretsa pakati pa $4,200 mpaka $10,000 m'matumba a eni nyumba pa nthawi yomwe akuyembekezeka kukhala ndi choyatsira mpweya chokhazikika padenga.

"Muyezo uwu udakambitsirana ndi omwe akukhudzidwa nawo, kuphatikiza opanga ma air conditioners, mabungwe akuluakulu, mabungwe othandizira, ndi mabungwe ogwira ntchito kuti akwaniritse izi," a Katie Arberg, Energy Efficiency and Renewable Energy (EERE), DOE, adauza atolankhani. .

HVAC Pros Hustle Kuti Mugwirizane ndi Zosintha

Omwe akuyenera kukhala osatetezedwa ndi malamulo atsopanowa ndi makontrakitala a HVAC ndi akatswiri ogwira ntchito molimbika omwe adzayike ndikusamalira zida zatsopano za HVAC.Ngakhale nthawi zonse ndiudindo wa akatswiri a HVAC kukhalabe apano ndi zomwe zikuchitika m'mafakitale, opanga adzafunika kuthera nthawi akufotokozera miyezo ya DOE ndi momwe imakhudzira ntchito m'munda.

"Ngakhale tikupereka moni kuyesetsa kuchepetsa mpweya, tikumvetsetsanso kuti padzakhala nkhawa kuchokera kwa eni nyumba zamalonda ponena za udindo watsopano," adatero Carl Godwin, woyang'anira malonda a HVAC ku CroppMetcalfe."Takhala tikugwirizana kwambiri ndi opanga malonda a HVAC ndipo tatenga nthawi yochuluka yophunzitsa akatswiri athu a nyenyezi zisanu pa miyezo ndi machitidwe atsopano omwe adzagwiritsidwe ntchito pa Jan. 1. Tikulandira eni eni amalonda kuti alankhule nafe ndi mafunso aliwonse. .”

Magawo Atsopano a Padenga la HVAC Akuyembekezeka

Malamulowa akusintha momwe ukadaulo wa HVAC umamangidwira kuti ukwaniritse zofunikira izi.Kwatsala miyezi iwiri yokha, kodi opanga zotenthetsera ndi kuziziritsa ali okonzeka kutsatira miyezo yomwe ikubwera?

Yankho ndi lakuti inde.Akuluakulu opanga kutentha ndi kuziziritsa alandira kusintha.

"Titha kupanga phindu motsatira njira izi monga gawo la ntchito yathu kuti tizitsatira malamulowa," a Jeff Moe, mtsogoleri wamabizinesi, bizinesi yogwirizana, North America, Trane adauza ACHR News."Chimodzi mwazinthu zomwe tidaziwona ndi mawu akuti 'Beyond Compliance.'Mwachitsanzo, tiwona zatsopano zochepetsera mphamvu zamagetsi za 2018, kusintha zinthu zomwe zilipo kale, ndikuwonjezera mphamvu zake, kuti zigwirizane ndi malamulo atsopano.Tiphatikizanso zosintha zina zamalonda m'malo okonda makasitomala mogwirizana ndi zomwe zikuchitika kuti tipereke mtengo wopitilira muyeso womwewo. ”

Akatswiri opanga ma HVAC nawonso achitapo kanthu kuti akwaniritse zitsogozo za DOE, pozindikira kuti akuyenera kumvetsetsa bwino kutsatiridwa ndi mphamvu zatsopano ndikupanga mapangidwe atsopano kuti akwaniritse kapena kupitilira miyezo yonse yatsopano.

Mtengo Wokwera Woyamba, Wotsika mtengo

Chovuta chachikulu kwa opanga ndikupanga ma RTU omwe amakwaniritsa zofunikira zatsopano popanda kuwononga ndalama zambiri kutsogolo.Machitidwe a Higher Integrated Energy Efficiency Ratio (IEER) adzafuna malo akuluakulu osinthanitsa kutentha, kuwonjezereka kwa mipukutu yosinthika komanso kugwiritsa ntchito makina osindikizira othamanga komanso kusintha kwa liwiro la fan pamagetsi owombera.

"Nthawi zonse pakakhala kusintha kwakukulu kwa malamulo, zomwe zimadetsa nkhawa kwambiri opanga, monga Rheem, ndi momwe malondawo amayenera kukonzedwanso," adatero Karen Meyers, wachiwiri kwa purezidenti, nkhani za boma, Rheem Mfg. Co., poyankhulana koyambirira kwa chaka chino. ."Kodi zosintha zomwe zasankhidwa zidzagwiritsidwa ntchito bwanji m'munda, zomwe zidakhalabe zabwino kwa wogwiritsa ntchito, komanso maphunziro omwe akuyenera kuchitika kwa makontrakitala ndi oyika."

Kuchiphwanya

DOE yaika chidwi chake pa IEER powunika mphamvu zamagetsi.Seasonal Energy Efficiency Ratio (SEER) imayika mphamvu zamakina potengera masiku otentha kapena ozizira kwambiri pachaka, pomwe IEER imawunika momwe makinawo amagwirira ntchito potengera momwe amagwirira ntchito munyengo yonse.Izi zimathandiza a DOE kuti awerenge molondola kwambiri ndikulemba gawo lomwe lili ndi mavoti olondola kwambiri.

Kusasinthika kwatsopano kuyenera kuthandiza opanga kupanga mayunitsi a HVAC omwe angakwaniritse miyezo yatsopano.

"Chimodzi mwazinthu zofunika pokonzekera chaka cha 2018 ndikukonzekera kusintha kwa DOE pamayendedwe a IEER, zomwe zidzafunika maphunziro kwa makasitomala pakusintha kumeneku ndi zomwe zikutanthauza," Darren Sheehan, director of light commercial products. , Daikin North America LLC, adauza mtolankhani Samantha Sine."Kutengera luso laukadaulo, mitundu yosiyanasiyana ya mafani amkati ndi kukakamiza kosiyanasiyana kumatha kubwera."

Bungwe la American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) likusinthanso miyezo yake malinga ndi malamulo atsopano a DOE.Zosintha zomaliza mu ASHRAE zidabwera mu 2015.

Ngakhale sizikudziwika bwino momwe miyezo idzawonekere, akatswiri akulosera izi:

Kukupiza magawo awiri pamagawo ozizirira 65,000 BTU/h kapena kukulirapo

Magawo awiri a kuzizira kwamakina pa mayunitsi 65,000 BTU/h kapena kukulirapo

Magawo a VAV angafunikire kukhala ndi magawo atatu a kuzizira kwamakina kuchokera pa 65,000 BTU/h-240,000 BTU/h

Magawo a VAV angafunikire kukhala ndi magawo anayi a kuziziritsa kwamakina pamayunitsi opitilira 240,000 BTU/s

Malamulo onse a DOE ndi ASHRAE adzasiyana malinga ndi boma.Akatswiri a HVAC omwe akufuna kukhala osinthika pakukula kwa miyezo yatsopano m'boma lawo akhoza kupita ku energycodes.gov/compliance.

Zatsopano Zamalonda za HVAC Installation Refrigerant Regulants

Malangizo a DOE HVAC aphatikizanso magawo omwe akhazikitsidwa kuti agwiritsidwe ntchito mufiriji ku US zokhudzana ndi satifiketi ya HVAC.Kugwiritsa ntchito mafakitale a hydrofluorocarbons (HFCs) kunathetsedwa mu 2017 chifukwa cha mpweya wowopsa wa carbon.Kumayambiriro kwa chaka chino, chilolezo chogulira cha DOE chochepetsa ozone-depleting substance (ODS) kwa obwezera kapena akatswiri ovomerezeka.Kugwiritsa ntchito pang'ono kwa ODS kunaphatikizapo ma hydrochlorofluorocarbons (HCFCs), ma chlorofluorocarbon (CFCs) ndipo tsopano ma HFC.

Chatsopano mu 2018 ndi chiyani?Akatswiri omwe akufuna kupeza mafiriji amtundu wa ODS adzafunika kukhala ndi satifiketi ya HVAC yokhala ndiukadaulo wogwiritsa ntchito ODS.Certification ndi yabwino kwa zaka zitatu.Malamulo a DOE adzafuna akatswiri onse ogwira ntchito za ODS kuti azisunga zolemba za ODS zomwe zimagwiritsidwa ntchito pazida zokhala ndi mapaundi asanu kapena kuposerapo a firiji.

Zolemba ziyenera kukhala ndi izi:

Mtundu wa refrigerant

Malo ndi tsiku loperekedwa

Kuchuluka kwa firiji yogwiritsidwa ntchito yotengedwa mugawo la HVAC

Dzina la wolandira kutumiza kwa refrigerant

Kusintha kwina kwatsopano pamiyezo ya refrigerant ya HVAC kutsikanso mu 2019. Akatswiri amatha kuyembekezera tebulo latsopano lotayikira komanso kuwunika kwapachaka kapena pachaka pazida zonse zomwe zimafunikira kuwunikanso kwa 30 peresenti ya firiji yamafakitale pogwiritsa ntchito ma 500 lbs a refrigerant, ndi cheke pachaka cha 20 peresenti ya zoziziritsira malonda zogwiritsa ntchito ma 50-500 lbs a firiji ndikuwunika pachaka kwa 10 peresenti kuti muziziziritsa muofesi ndi nyumba zogona.

Kodi Kusintha kwa HVAC Kudzakhudza Bwanji Ogwiritsa Ntchito?

Mwachilengedwe, kukweza kwa makina a HVAC osagwiritsa ntchito mphamvu kumatumiza zododometsa pamakampani onse otenthetsera ndi kuziziritsa.M'kupita kwanthawi, eni mabizinesi ndi eni nyumba adzapindula ndi miyezo yokhwima ya DOE pazaka 30 zikubwerazi.

Zomwe ogawa a HVAC, makontrakitala ndi ogula akufuna kudziwa ndi momwe kusinthaku kungakhudzire mtengo woyambira ndi kuyika kwa makina atsopano a HVAC.Kuchita bwino sikutsika mtengo.Chiwopsezo choyamba chaukadaulo chikuyembekezeka kubweretsa ma tag apamwamba.
