Hauv tsab xov xwm luv luv no, kuv xav sau cov ntsiab lus vim li cas OSB lub twj tso kua mis kub tau cog lus rau propane ua cov roj tub yees tsis yog lwm cov kev daws teeb meem nrov heev.
Lub sijhawm no, tom qab tso tawm OSB inverter thiab tam sim no nrog OSB inverter EVI, ntau tus neeg tsim khoom thiab cov neeg tsim qauv tau nug peb tias vim li cas peb tsis tsim cov twj siv hluav taws xob nrog R32.
Thawj qhov thiab tej zaum ib qho tseem ceeb tshaj plaws yog los ntawm Environmental Point of view. Yog tias koj tsis paub txog GWP (Lub Ntiaj Teb Warming Potential), GWP yog ib qho txheeb ze ntsuas seb lub tsev cog khoom cua kub npaum li cas hauv huab cua. R32 yog tsim los ntawm 50% R410A thiab 50% R125. Yog li txawm tias muaj GWP qis dua R410A, nws tseem yog tus nqi siab thaum piv rau cov tub yees ntuj, xws li CO2 lossis propane.
Vim li ntawd, los ntawm peb qhov kev xav, R32 yog qhov kev daws teeb meem nruab nrab ntawm cov tub yees siv tam sim no thiab yav tom ntej, cov tub yees ntuj.
Lwm lub ntsiab lus tseem ceeb, tshwj xeeb tshaj yog thaum peb tham txog cov khoom siv cua kub cua sov yog daim ntawv qhia kev ua haujlwm. Vim li ntawd, hauv peb thawj zaug ntawm cov twj tso cua sov, peb twv rau EVI (Enhanced Vapor Injection) compressors, uas txo cov kev txwv ntawm R410A los ua qhov kub thiab txias ntawm qhov tsis tshua muaj sab nraum zoov. Nyob rau hauv rooj plaub ntawm R32, nws yog qhov tseeb tias R32 compressors muaj kev ua tau zoo dua thiab lawv siv cov tub yees me me (15% tsawg dua roj nqi piv rau R410A) nrog rau kev ua haujlwm cua sov zoo dua ntawm qhov kub thiab txias.
Txawm li cas los xij, daim ntawv qhia kev ua haujlwm ntawm R32 yog qhov zoo ib yam li R410A thiab rau cov cua kub hauv cov twj tso kua mis, cov tuam ntxhab tseem tab tom nrhiav kev daws teeb meem nrog EVI thev naus laus zis. Daim duab tom ntej no tau coj los ntawm Danfoss Commercial Compressors R32 Compressor Technology thiab muaj kev sib piv ntawm ib qho R32 EVI Compressor nrog R410A tus qauv.
Yog tias koj piv cov duab no nrog rau ib qho tom ntej, los ntawm Copeland's Catalog. Koj tuaj yeem tshawb xyuas tias R32 lossis R410 lub hnab ntawv ua haujlwm nrog R290, qhov nyiaj tshuav tau pom meej nrog R290.
Nyob rau hauv cov huab cua ib txwm siv cov cua kub twj tso kua mis, DHW ntau lawm kub yog nyob ib ncig ntawm 45ºC-50ºC yam tsis muaj kev pab txhawb nqa. Hauv qee qhov tshwj xeeb, koj tuaj yeem ncav cuag 60ºC tab sis nyob rau hauv rooj plaub ntawm R290, cov twj tso kua cua sov tuaj yeem ua rau siab tshaj 70ºC. Qhov no yog qhov tseem ceeb heev rau DHW ntau lawm tab sis kuj yog tias koj xav hloov kho koj lub qub kev teeb tsa thiab khaws koj cov qub radiators. Ua tsaug rau qhov no, tam sim no nws muaj peev xwm ua haujlwm ncaj qha nrog lub tshuab hluav taws xob thiab tsis hloov tag nrho cov kev teeb tsa.
Peb qhov laj thawj no tau tso OSB lub twj tso kua mis tso rau hauv kev pom zoo ntawm R290. Peb ntseeg ruaj khov tias yav tom ntej yuav dhau los ntawm propane ua cov tub yees. SAIB NTAWM LUB ntiaj teb thiab saib xyuas koj txoj kev nplij siab
Lus Cim:
Qee cov ntawv tau muab los ntawm Is Taws Nem. Yog tias muaj kev ua txhaum cai, thov hu rau peb kom tshem tawm. Yog tias koj txaus siab rau cov khoom siv twj tso kua mis, thov hu rau OSB lub tuam txhab kub twj tso kua mis, peb yog koj qhov kev xaiv zoo tshaj.
