Lub cev muaj zog: Watt (W)
Cov txheej txheem thoob ntiaj teb rau kev sib pauv cua sov (tseem hu ua cua sov) yog watt (W). Qhov no yog qhov feem ntau thiab nyiam chav nyob hauv cov xwm txheej kev lag luam thoob ntiaj teb, ua kom muaj kev nkag siab zoo ib yam ntawm cov koom tes hauv kev lag luam thoob ntiaj teb.
1. Unit txhais:Ib watt sib raug rau ib joule ib ob (1W=1J / s), uas yog tus nqi ntawm cov cua sov hloov los ntawm cov khoom siv hluav taws xob sib pauv hauv ib chav tsev ntawm lub sijhawm. Piv txwv li, lub tshav kub exchanger nrog lub tshav kub pauv ntawm 5000W txhais tau hais tias nws muaj peev xwm hloov 5000 joules ntawm tshav kub ib ob.
2. Feem ntau siv ntau chav nyob:Vim muaj kev hloov pauv tseem ceeb hauv kev sib pauv cua sov hauv cov chaw tsim khoom, ntau chav nyob feem ntau siv rau hauv kev siv tswv yim. Cov no yuav tsum tau qhia meej meej hauv cov ntaub ntawv kev lag luam thoob ntiaj teb:
- Kilowatt (kW): 1 kW=1000 W, haum rau me me thiab nruab nrab- cov khoom siv hluav taws xob loj (xws li cov cua sov hauv tsev, cov cua txias me me), thiab yog ib chav tsev uas nquag siv nyob rau hauv kev lag luam thoob ntiaj teb cov lus hais thiab cov lus ntsuas.
- Megawatt (MW): 1 MW=10⁶ W, haum rau cov khoom siv loj loj (xws li lub tshuab fais fab condensers thiab chemical reactor heat exchangers), feem ntau yog siv rau hauv loj -scale project bidding thiab technical agreements.
. Feem ntau Siv Chav nyob hauv Lwm Thaj Chaw / Kev Lag Luam
Qee qhov kev lag luam txawv teb chaws (xws li North America thiab qee qhov kev lag luam ib txwm nyob hauv Europe) tseem yuav siv tsis yog - cov chav nyob hauv ntiaj teb; Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nkag siab txog kev sib raug zoo ntawm kev hloov pauv kom tsis txhob muaj kev sib txuas lus yuam kev:
1. Imperial units: British thermal units ib teev (BTU/h)
- Kev txhais: 1 BTU / h sawv cev rau kev hloov pauv ntawm 1 British thermal chav tsev ntawm cua sov ib teev thiab yog ib chav tsev uas nquag siv nyob rau hauv North American HVAC thiab tub yees industries.
- Kev sib raug zoo ntawm kev hloov pauv: 1 BTU / h ≈ 0.293 W, 1 kW ≈ 3412 BTU / h (Qhov no yog cov qauv hloov pauv tseem ceeb rau kev lag luam thoob ntiaj teb thiab yuav tsum tau cim kom raug).
- Daim ntawv thov scenario: Thaum sib txuas lus nrog US thiab Canadian cov neeg muas zaub hais txog cov cua txias me me thiab cov twj tso kua mis kub sib hloov, nws yog ib qho tsim nyog los muab ob W (lossis kW) thiab BTU / h units ib txhij los txhim kho cov ntaub ntawv sib xws.
2. kilocalories ib teev (kcal / h)
- Txhais: 1 kcal / h sawv cev rau kev hloov ntawm 1 kilocalorie ntawm tshav kub ib teev. Chav tsev no tau siv dav hauv Tebchaws Europe, Nyiv, Kaus Lim Qab Teb, thiab nyob rau theem pib ntawm kev lag luam hauv tsev, thiab tseem siv nyob rau hauv qee qhov chaw ua haujlwm niaj hnub no.
- Kev sib raug zoo: 1 kcal/h ≈ 1.163 W, 1 kW ≈ 859.8 kcal/h.
- Daim ntawv thov scenario: Thaum koom tes nrog cov tuam txhab tshuaj ib txwm siv hauv Nyij Pooj, Kaus Lim Qab Teb, thiab Sab Hnub Tuaj Europe, nws yog ib qho tseem ceeb uas yuav tau txiav txim siab seb lawv puas tau siv los ntsuas qhov ntsuas no. Nws raug nquahu kom suav nrog cov lus piav qhia hloov dua siab tshiab hauv cov ntaub ntawv thev naus laus zis.
Cov ntsiab lus tseem ceeb rau kev siv chav tsev
Ua ntej siv cov txheej txheem thoob ntiaj teb
Hauv cov ntawv cog lus kev lag luam txawv teb chaws, cov ntawv tsis sib xws, thiab cov khoom siv phau ntawv, ua ntej siv watts (W) thiab nws qhov ntau (kW, MW). Tsis yog - cov chav nyob thoob ntiaj teb yuav raug siv los ua cov ntaub ntawv ntxiv, tab sis zam tsis txhob siv lawv los ua lub hauv paus tseem ceeb los tiv thaiv kev ua yuam kev hauv cov lus hais thiab xaiv cov khoom vim qhov tsis sib xws.
Qhia meej txog lub hauv paus hloov dua siab tshiab
Yog tias tus neeg siv khoom thov kev siv tsis yog - units thoob ntiaj teb, cov qauv hloov pauv yuav tsum tau qhia hauv cov ntaub ntawv kom ntseeg tau tias ob tog muaj kev nkag siab zoo ib yam ntawm cov ntsuas kev ua tau zoo (xws li, "Cov khoom siv hluav taws xob hloov pauv yog 5 kW, uas yog kwv yees li 17060 BTU / h").
Qhov txawv ntawm "heat exchange rate" thiab "heat transfer coefficient"
Zam kev tsis sib haum xeeb- chav tsev rau cov nqi pauv hluav taws xob yog W (lub zog / lub sijhawm), thaum chav tsev rau cov hluav taws kub hloov coefficient (K tus nqi) yog W / (m²·°C). Ob nqe lus no piav qhia txog "tag nrho cov kev hloov hluav taws xob" thiab "qhov muaj peev xwm hloov hluav taws xob hauv ib cheeb tsam," feem, thiab yuav tsum tau ua kom pom tseeb hauv kev sib txuas lus thoob ntiaj teb.
