I-US Department of Energy's (DOE's) izikhokelo ezintsha zokuthobela, ezichazwa “njengowona mgangatho wokonga umbane omkhulu kwimbali,” ziya kuba nefuthe elisemthethweni kushishino lokufudumeza nokupholisa.

Imigangatho emitsha, echazwe kwi-2015, icwangciselwe ukuba iqalise ukusebenza ngoJanuwari 1, 2018 kwaye iya kutshintsha indlela abavelisi bezobunjineli bezorhwebo be-rooftop air conditioners, iimpompo zokushisa kunye nokufudumala kwezakhiwo "eziphantsi".njengeevenkile ezithengisayo, amaziko emfundo kunye nezibhedlele ezikwinqanaba eliphakathi.

Ngoba?Injongo yomgangatho omtsha kukuphucula ukusebenza kakuhle kwe-RTU kunye nokunciphisa ukusetyenziswa kwamandla kunye nenkcitho.Kucingelwa ukuba olu tshintsho luza kusindisa abanini propati imali eninzi ekuhambeni kwexesha- kodwa, ewe, izigunyaziso zika-2018 zibonisa imingeni ethile kwabo bachaphazelekayo kulo lonke ishishini le-HVAC.

Makhe sijonge ezinye zeendawo apho ishishini le-HVAC liza kuva impembelelo yotshintsho:

Iikhowudi zokwakha / ulwakhiwo - iikontraki zokwakha ziya kufuneka zilungelelanise iiplani zomgangatho kunye neemodeli zesakhiwo ukuhlangabezana nemigangatho emitsha.

Iikhowudi ziya kwahluka ngokwelizwe - iJografi, imozulu, imithetho yangoku, kunye neendawo zonke ziya kuchaphazela indlela ilizwe ngalinye elamkela ngayo iikhowudi.

Ukukhutshwa okucuthiweyo kunye ne-carbon footprint - I-DOE iqikelela ukuba imigangatho iya kunciphisa ungcoliseko lwekhabhoni nge-885 yezigidi zeetoni zeemetric.

Abanini bezakhiwo kufuneka baphucule - Iindleko zangaphambili ziya kulungiswa nge-$ 3,700 kwi-savings per RTU xa umninimzi ethatha indawo okanye ebuyisela izixhobo ezindala.

Iimodeli ezintsha zisenokungabonakali ngokufanayo - Ukuqhubela phambili ekusebenzeni kwamandla kuya kubangela ukuyila okutsha kwii-RTU.

Ukunyuka kweentengiso kwiikontraki ze-HVAC / abasasazi - Iikontraki kunye nabasasazi banokulindela ukunyuka kweepesenti ze-45 kwiintengiso ngokubuyisela okanye ukuphumeza i-RTU entsha kwizakhiwo zorhwebo.

Ishishini, ngokwetyala lalo, liyakhula.Makhe sibone ukuba njani.

Inkqubo yesiGaba eSibini yeeKontraka zeHVAC

I-DOE iya kukhupha imigangatho emitsha kwizigaba ezibini.ISigaba sokuQala sigxininise ekunyuseni kokusetyenziswa kwamandla kuzo zonke ii-RTU zomoya womoya ngeepesenti ezili-10 ukususela ngoJanuwari 1, 2018. Isigaba seSibini, esicwangciselwe i-2023, siya kudibanisa ukunyuka ukuya kwi-30 ekhulwini kwaye ibandakanye iziko lomoya ofudumeleyo, kwakhona.

I-DOE iqikelela ukuba ukuphakamisa umgangatho ekusebenzeni kuya kunciphisa ukufudumeza kwezorhwebo kunye nokusetyenziswa kokupholisa nge-1.7 yetriliyoni kWh kwiminyaka engamashumi amathathu ezayo.Ukwehliswa okukhulu kokusetyenziswa kwamandla kuya kubuyisela phakathi kwe-$4,200 ukuya kwi-10,000 yeedola kwi-avareji yeepokotho zomnini wesakhiwo kwixesha elilindelekileyo le-air conditioner yophahla oluqhelekileyo.

"Lo mgangatho othile uxoxisana nabachaphazelekayo abachaphazelekayo, kubandakanywa nabavelisi bee-air conditioners zorhwebo, imibutho emikhulu yoshishino, izibonelelo, kunye nemibutho esebenzayo ukuze kugqitywe lo mgangatho," uKatie Arberg, ukuSebenza kwaMandla kunye noNxibelelwano lwaMandla aVuselelwayo (EERE), i-DOE, uxelele iphephandaba. .

I-HVAC Pros Hustle ukuhambisana notshintsho

Ezona zinokwenzeka ukuba zibanjwe zingenaludwe yimithetho emitsha ziikontraka ze-HVAC kunye neengcali ezisebenza nzima eziya kuthi zifake kwaye zigcine izixhobo ezitsha ze-HVAC.Nangona isoloko iluxanduva lwengcali ye-HVAC ukuhlala ngoku kunye nophuhliso lweshishini kunye neendlela, abavelisi kuya kufuneka bachithe ixesha bechaza imigangatho ye-DOE kunye nendlela eyichaphazela ngayo umsebenzi ebaleni.

"Nangona sibulisa umzamo wokunciphisa ukukhutshwa kwezinto ezikhutshwayo, siyaqonda kwakhona ukuba kuya kubakho inkxalabo evela kubanini beepropati zorhwebo malunga nesigunyaziso esitsha," kusho uCarl Godwin, umphathi wezorhwebo we-HVAC kwiCroppMetcalfe.“Siye sanxibelelana ngokusondeleyo nabavelisi be-HVAC abarhwebayo kwaye sithathe ixesha elininzi lokuqeqesha amagcisa ethu eenkwenkwezi ezintlanu kwimigangatho emitsha kunye neendlela eziya kuphunyezwa ngoJan. 1. Siyabamkela abanini beepropati zorhwebo ukuba baqhagamshelane nathi ngayo nayiphi na imibuzo. .”

Kulindelwe iiYunithi zeHVAC kuphahla olutsha

Imithetho iyayitshintsha indlela itekhnoloji yeHVAC eyakhiwe ngayo ukuze ihlangabezane nezi mfuno ziphuculweyo zokusebenza.Kwiinyanga ezimbini kuphela eziseleyo, ngaba abavelisi bokufudumeza kunye nokupholisa bayilungele imigangatho ezayo?

Impendulo nguewe.Abavelisi abakhulu bokufudumeza kunye nokupholisa balwamkele utshintsho.

"Sinokwakha ixabiso kunye nale mizila yendlela yokwenza njengenxalenye yomsebenzi wethu ukuthobela le mimiselo," uJeff Moe, inkokeli yoshishino lwemveliso, ishishini elihlangeneyo, eNyakatho Melika, uTrane utshele i-ACHR News.“Enye yezinto esizijongileyo ligama elithi 'Ngaphandle kokuthotyelwa.'Umzekelo, siza kujonga ubuncinci bokusebenza kwamandla ka-2018, silungise iimveliso ezikhoyo, kwaye sandise ukusebenza kakuhle kwazo, ukuze zihambelane nemigaqo emitsha.Siza kubandakanya utshintsho olongezelelweyo lwemveliso kwiindawo ezinomdla wabathengi kunye neendlela zokubonelela ngexabiso elingaphezulu nangaphaya kokunyuka okusebenzayo. "

Iinjineli ze-HVAC nazo zithathe amanyathelo abalulekileyo ukuhlangabezana nezikhokelo ze-DOE, ziqonda ukuba kufuneka zibe nokuqonda okucacileyo kokuthotyelwa kwemiyalelo emitsha kwaye zenze uyilo lwemveliso emitsha ukuhlangabezana okanye ukodlula yonke imigangatho emitsha.

Iindleko zokuQala eziPhezulu, iindleko zokuSebenza eziPhantsi

Owona mceli mngeni mkhulu kubavelisi kukuyila ii-RTU ezihlangabezana neemfuno ezintsha ngaphandle kokufumana iindleko eziphezulu ngaphambili.Iinkqubo eziPhakamileyo eziDityanisiweyo zokuSebenza ngokuSebenza kakuhle kwaMandla (IEER) ziya kufuna iindawo ezinkulu zokutshintshiselana kobushushu, ukuskrola okumodareyithiweyo okwandisiweyo kunye nokusetyenziswa kwecompressor yesantya esiguquguqukayo kunye nohlengahlengiso kwizantya zabalandeli kwiinjini zokuvuthela.

"Nanini na kukho utshintsho olukhulu lolawulo, eyona nkxalabo inkulu kubavelisi, njengoRheem, kukuba imveliso kufuneka ihlaziywe njani," utshilo uKaren Meyers, usekela mongameli, imicimbi karhulumente, uRheem Mfg. Co., kudliwanondlebe ekuqaleni kwalo nyaka. ."Utshintsho olucetywayo luza kusetyenziswa njani ebaleni, ngaba imveliso iya kuhlala inexabiso elifanelekileyo kumsebenzisi wokugqibela, kwaye loluphi uqeqesho ekufuneka lwenzeke kwiikontraka kunye nabafakeli."

Ukuyichitha

I-DOE ibeke ugxininiso lwayo kwi-IEER xa ivavanya ukusebenza kakuhle kwamandla.Umlinganiselo wokuSebenza kwamandla eXesha loNyaka (SEER) ulinganisa ukusebenza kwamandla omatshini ngokusekelwe kwezona ntsuku zishushu okanye zibanda kakhulu zonyaka, ngelixa i-IEER ivavanya ukusebenza kakuhle komatshini ngokusekelwe kwindlela asebenza ngayo kwixesha lonke lonyaka.Oku kunceda i-DOE ukuba ifumane ufundo oluchaneke ngakumbi kwaye ileyibhelishe iyunithi enomlinganiselo ochanekileyo.

Inqanaba elitsha lokuhambelana kufuneka lincede abavelisi bayile iiyunithi ze-HVAC eziza kuhlangabezana nemigangatho emitsha.

"Enye yezinto ezifunekayo ukuze ulungele i-2018 ilungiselela utshintsho lwe-DOE ye-metric yokusebenza kwi-IEER, eya kufuna imfundo kubathengi kolo tshintsho kwaye oko kuya kuthetha ntoni," uDarren Sheehan, umlawuli weemveliso ezilula zorhwebo. , Daikin North America LLC, uxelele intatheli uSamantha Sine."Ngokwembono yetekhnoloji, iintlobo ezahlukeneyo zabalandeli bobonelelo lwangaphakathi kunye noxinzelelo oluguquguqukayo lwamandla zinokungena."

I-American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) ikwalungisa imigangatho yayo ngokwemigaqo emitsha ye-DOE.Utshintsho lokugqibela kwi-ASHRAE lweza ngo-2015.

Nangona kungacacanga ukuba imigangatho iya kujongeka njani, iingcali zenza olu qikelelo:

Ifeni enezigaba ezibini kwiiyunithi zokupholisa 65,000 BTU/h okanye ngaphezulu

Izigaba ezibini zokupholisa koomatshini kwiiyunithi ezingama-65,000 BTU/h okanye ezinkulu

Iiyunithi ze-VAV zinokufuneka ukuba zibe nezigaba ezithathu zokupholisa ngoomatshini ukusuka kwi-65,000 BTU/h-240,000 BTU/h

Iiyunithi ze-VAV zinokufuneka ukuba zibe nezigaba ezine zokupholisa ngoomatshini kwiiyunithi ezinkulu kune-240,000 BTU/s

Yomibini imimiselo ye-DOE kunye ne-ASHRAE iya kwahluka ukusuka kwilizwe ukuya kwelinye.Iingcali ze-HVAC ezifuna ukuhlala zihlaziyiwe kuphuhliso lwemigangatho emitsha kwilizwe labo banokundwendwela energycodes.gov/compliance.

Imithetho emitsha yokuFakela iFriji yeHVAC yoRhwebo

Izikhokelo ze-DOE HVAC ziya kubandakanya iiparamitha ezimiselwe ukusetyenziswa kwefriji e-US ehambelana nesiqinisekiso se-HVAC.Ukusetyenziswa kweshishini le-hydrofluorocarbons (HFCs) kwapheliswa ngo-2017 ngenxa yokukhutshwa kwekhabhoni eyingozi.Ebutsheni balo nyaka, i-DOE inesibonelelo sokuthenga i-ozone-depleting substance (ODS) kubabuyiseli abaqinisekisiweyo okanye amagcisa.Ukusetyenziswa okulinganiselweyo kwe-ODS kuquke ii-hydrochlorofluorocarbons (HCFCs), ii-chlorofluorocarbons (CFCs) kwaye ngoku ii-HFCs.

Yintoni entsha ngo-2018?Amagcisa afuna ukufumana iifriji zodidi lwe-ODS ziya kufuneka zibe nezatifikethi ze-HVAC ezinobungcali ekusebenziseni i-ODS.Isiqinisekiso silungile iminyaka emithathu.Imimiselo ye-DOE iya kufuna ukuba bonke abachwephesha abaphatha izinto ze-ODS bagcine iirekhodi zokulahlwa kwe-ODS ezisetyenziselwa izixhobo ezineepounds ezintlanu okanye ngaphezulu zefriji.

Iirekhodi mazibandakanye olu lwazi lulandelayo:

Uhlobo lwefriji

Indawo kunye nomhla wokulahla

Ubungakanani befriji esetyenzisiweyo ekhutshwe kwiyunithi ye-HVAC

Igama lomamkeli wogqithiselo lwefriji

Olunye utshintsho olutsha kwimigangatho yefriji ye-HVAC nayo iya kuhla ngo-2019. Amagcisa anokulindela itafile entsha yokuvuza kunye nokuhlolwa kokuvuza kwekota okanye ngonyaka kuzo zonke izixhobo ezifuna ukuphononongwa kweepesenti ze-30 zenkqubo yefriji yefriji usebenzisa i-500 lbs yefriji, i isheke yonyaka yeepesenti ezingama-20 zokupholisa intengiso kusetyenziswa i-50-500 lbs yesikhenkcisi kunye nohlolo lonyaka lwe-10 ekhulwini lokupholisa intuthuzelo kwiofisi nakwizakhiwo zokuhlala.

Ingaba iinguqu ze-HVAC ziya kubachaphazela njani abathengi?

Ngokwendalo, uphuculo kwiinkqubo ze-HVAC ezisebenzisa amandla amandla ziya kuthumela amaza othusayo kulo lonke ishishini lokufudumeza kunye nokupholisa.Ngexesha elide, abanini bamashishini kunye nabanini zindlu baya kuxhamla kwimigangatho engqongqo ye-DOE kule minyaka ingama-30 izayo.

Yintoni abasasazi be-HVAC, iikontraka kunye nabathengi abafuna ukwazi ukuba utshintsho luya kuyichaphazela njani imveliso yokuqala kunye neendleko zofakelo lweenkqubo ezintsha zeHVAC.Ukusebenza kakuhle akuzisi.I-wave yokuqala yetekhnoloji inokuzisa iithegi zamaxabiso aphezulu.

Sekunjalo, abavelisi be-HVAC bahlala benethemba lokuba iinkqubo ezintsha ziya kubonwa njengotyalo-mali oluhlakaniphile kuba ziya kuhlangabezana neemfuno zexesha elifutshane kunye nexesha elide zabanini bamashishini.

"Siyaqhubeka nokuba neengxoxo kwi-2018 kunye ne-2023 ye-DOE ye-rooftop yemigaqo esebenzayo eya kuba nefuthe kwishishini lethu," kusho uDavid Hules, umlawuli wezentengiso, umoya wezorhwebo, u-Emerson Climate Technologies Inc. uthe ngoJanuwari odlulileyo.Ngokukodwa, besithetha nabathengi bethu ukuze baqonde iimfuno zabo kunye nendlela izisombululo zethu zokumodareyitha, kubandakanya nezisombululo zethu zoxinzelelo lwamanqanaba amabini, zinokubanceda bafezekise impumelelo ephezulu ngezibonelelo eziphuculweyo.

Ibe luxanduva olunzima kubenzi bokuhlaziya ngokupheleleyo iiyunithi zabo ukuhlangabezana namanqanaba amatsha okusebenza, nangona abaninzi besebenza nzima ukuqinisekisa ukuba bakwenza oko ngexesha.

"Impembelelo enkulu kubavelisi kufuneka baqinisekise ukuba zonke iimveliso zabo zihlangabezana namanqanaba amancinci," kusho uMichael Deru, umphathi wezobunjineli, iNational Renewable Energy Laboratory (NREL).“Eyona mpembelelo inkulu ilandelayo iya kuba kwizixhobo eziluncedo kuba kufuneka bahlengahlengise iinkqubo zabo nokubala ukonga.Kuya kuba nzima kubo ukuphuhlisa iinkqubo ezintsha zempumelelo kwaye babonise ugcino xa eyona bar isebenzayo ihlala iphezulu.
