Kilowatt Teev Sij Hawm
Txoj Kev 1 ntawm 3: Kwv yees Kilowatt Teev Sijhawm los ntawm Cov Ntawv Siv Khoom Siv
Kauj Ruam 1. Nrhiav lub wattage ntawm daim ntawv lo khoom siv
Feem ntau cov cuab yeej siv hluav taws xob muaj daim ntawv lo lub zog nyob tom qab lossis lub hauv paus ntawm cov khoom siv. Saib ntawm no kom pom cov wattage, teev ua "W." Qhov no feem ntau yog lub zog siab tshaj plaws uas lub cuab yeej ua haujlwm ntawm, uas yuav ntau dua li qhov nruab nrab wattage tiag. Cov theem hauv qab no yuav pom qhov kwv yees kwv yees ntawm kWh los ntawm tus lej no, tab sis koj qhov kev siv kWh tiag tiag feem ntau qis dua.
Qee cov cuab yeej qhia ntau yam ntawm watts, xws li "200-300W." Nws yuav yog qhov tseeb dua los xaiv qhov nruab nrab ntawm qhov no, lossis 250W hauv qhov piv txwv no
Kauj Ruam 2. Muab cov wattage los teev ua txhua hnub
Watts ntsuas lub zog, lossis lub zog siv sijhawm dhau los. Kev sib npaug los ntawm ib lub sijhawm muab rau koj cov lus teb hais txog lub zog, uas yog yam tseem ceeb rau koj daim nqi hluav taws xob.
-
Piv txwv:
Lub qhov rais loj kiv cua ntsuas ntawm 250 watts khiav rau nruab nrab ntawm 5 teev hauv ib hnub. Cov kiv cua txhua hnub watt-teev sib npaug (250 watts) x (5 teev / hnub) = 1250 watt-teev nyob rau ib hnub.
- Rau cov cua txias thiab cov cua sov ua kom sov, sib cais cov lus sib tw rau txhua lub caij.
- Cov tub yees tsuas yog siv lub zog kwv yees li ⅓ ntawm lub sijhawm, lossis kwv yees li 8 teev nyob rau ib hnub yog tias koj tsis tau tshem lawv.
Kauj Ruam 3. Sib faib qhov txiaj ntsig los ntawm 1, 000
Ib kilowatt yog sib npaug rau 1, 000 watts, yog li cov kauj ruam no hloov koj cov lus teb los ntawm watt teev rau kilowatt teev.
-
Piv txwv:
Koj tau suav tias koj tus kiv cua siv 1250 watt teev ntawm lub zog ib hnub. (1250 watt teev / hnub) ÷ (1000 watts / 1 kilowatt) = 1.25 kilowatt teev hauv ib hnub.
Kauj Ruam 4. Muab koj cov lus teb los ntawm cov hnub uas koj tab tom ntsuas
Tam sim no koj paub pes tsawg kilowatt-teev (kWh) lub cuab yeej siv txhua hnub. Txhawm rau xam koj cov kWH ib hlis lossis ib xyoos, tsuas yog suav nrog cov hnub nyob rau lub sijhawm ntawd.
-
Piv txwv:
Hauv ib lub hlis 30-hnub, koj tus kiv cua yuav siv (1.25 kWh / hnub) x (30 hnub / hli) = 37.5 kWh / hli.
-
Piv txwv:
Yog tias koj kiv cua khiav txhua hnub rau ib xyoos, nws yuav siv (1.25 kWh / hnub) x (365 hnub / xyoo) = 456.25 kWh / xyoo.
Kauj Ruam 5. Sib npaug los ntawm tus nqi hluav taws xob ib kWh
Koj daim nqi hluav taws xob teev tus nqi ib kilowatt teev. Muab tus lej no los kWh txhawm rau nrhiav cov nyiaj uas koj tuaj yeem xav kom them.
-
Piv txwv:
Yog tias lub zog nqi 17 xees / kWh, khiav lub kiv cua yuav raug nqi (0.17 las / kWh) x (456.25 kWh / xyoo) = $ 77.56 toj xyoo (sib npaug mus rau qhov ze ib xees).
- Nco ntsoov tias kwv yees raws li teev wattage yog qhov siab tshaj. Qhov tseeb koj yuav raug them tsawg dua li qhov no.
- Yog tias koj tab tom saib thaj tsam sib txawv dua li thaj chaw koj nyob, tshawb hauv online kom pom tus nqi hluav taws xob. Rau Asmeskas cov chaw, pib nrog EIA lub vev xaib.
Txoj Kev 2 ntawm 3: Xam Kilowatt Teev Los Ntawm Amps thiab Voltage
Kauj Ruam 1. Nrhiav qhov ntsuas amps ntawm koj lub cuab yeej
Qee lub npe khoom siv tsis teev cov watts. Hauv qhov xwm txheej no, nrhiav kev ntsuas amp lossis "A" hloov chaw.
Lub laptop thiab lub xov tooj them nyiaj tuaj yeem sau ob qhov tseem ceeb amp. Siv ib daim ntawv lo cim npe
Kauj Ruam 2. Nrhiav qhov hluav taws xob hauv koj cheeb tsam
Hauv Tebchaws Meskas thiab ob peb lub tebchaws, tus qauv hluav taws xob hauv tsev yog 120V. Hauv EU thiab feem ntau ntawm lub ntiaj teb, qhov hluav taws xob nyob nruab nrab ntawm 220 thiab 240V.
Hauv Teb Chaws Asmeskas, qee cov cuab yeej siv loj xws li tshuab ntxhua khaub ncaws tuaj yeem txuas rau hauv 240V tshwj xeeb. Txheeb xyuas daim ntawv lo khoom ntsuas qhov ntsuas hluav taws xob kom paub. (Daim ntawv qhia tsuas qhia rau koj pom zoo qhov hluav taws xob, tab sis koj tuaj yeem xav tias cov khoom siv tau teeb tsa zoo tshaj qhov kev pom zoo no.)
Kauj Ruam 3. Muab cov amps thiab volts ua ke
Kev sib tw amps thiab volts muab lus teb rau koj hauv watts, lossis hluav taws xob.
-
Piv txwv:
Daim ntawv lo microwave sau 6.5 amps thiab txuas rau hauv 120V qhov hluav taws xob. Nws siv 6.5 amps x 120 volts = 780 kwv.
Kauj Ruam 4. Muab cov xuab moos los siv ib hnub
Lub wattage qhia koj tias tus nqi zog tau siv thaum lub tshuab ua haujlwm. Sib npaug wattage los ntawm tus lej teev cov cuab yeej ua haujlwm nruab nrab hnub.
-
Piv txwv:
Yog tias microwave siv sijhawm ib nrab teev hauv ib hnub, sib npaug 780 watts x 0.5 teev / hnub = 390 watt teev hauv ib hnub.
Kauj Ruam 5. Sib faib los ntawm 1000
Qhov no hloov pauv los ntawm watt teev rau kilowatt teev.
-
Piv txwv:
390 watt teev / hnub ÷ 1000 watts / kilowatt = 0.39 kilowatt teev hauv ib hnub.
Kauj Ruam 6. Ua kom ntau ntxiv kom pom cov kilowatt teev rau lub sijhawm loj dua
Piv txwv li, yog tias koj xav paub seb pes tsawg kilowatt teev koj yuav raug them rau lub sijhawm them nqi 31-hnub, muab koj cov lus teb dhau 31 hnub.
-
Piv txwv:
0.39 kilowatt teev / hnub x 31 hnub = 12.09 kilowatt teev.
Txoj Kev 3 ntawm 3: Siv Lub Hwj Huam Lub Hwjchim
Kauj Ruam 1. Yuav lub ntsuas hluav taws xob online
Kuj tseem hu ua watt meter lossis kilowatt meter, cov cuab yeej no ntsuas lub zog tiag uas koj cov cuab yeej siv. Qhov no feem ntau yog qhov tseeb dua li siv cov cuab yeej daim ntawv lo.
Yog tias koj paub txog cov kws kho hluav taws xob cov cuab yeej, koj tuaj yeem siv lub multimeter hloov. Qhov no xav tau kev nkag mus rau cov khoom siv hluav taws xob thaum nws tau ntsaws. Tsis tas yuav hais, tsis txhob sib cais ib yam tshwj tsis yog koj paub tias koj tab tom ua dab tsi
Kauj Ruam 2. Ntsuas lub ntsuas ntsuas nruab nrab ntawm lub qhov hluav taws xob thiab cov khoom siv
Txuas lub ntsuas fais fab mus rau ntawm phab ntsa. Txuas lub cuab yeej rau hauv lub ntsuas hluav taws xob.
Kauj Ruam 3. Ntsuas lub kilowatt teev
Teem koj lub ntsuas hluav taws xob los tso saib kilowatt teev. Tsuav koj khaws lub ntsuas hluav taws xob txuas nrog, nws yuav tsum suav tag nrho cov kilowatt teev ntawm cov khoom siv txuas nrog.
- Yog tias koj lub ntsuas hluav taws xob tsuas yog ntsuas watts, koj tuaj yeem siv cov txheej txheem saum toj no los xam kilowatt teev los ntawm qhov ntsuas ntawd.
- Xa mus rau cov lus qhia ntsuas lub zog yog tias koj tsis paub yuav hloov nws li cas.
Kauj Ruam 4. Siv lub cuab yeej zoo li koj ib txwm ua
Qhov ntev koj tawm ntawm lub ntsuas hluav taws xob ntsaws rau hauv, qhov tseeb dua nws qhov kev suav yuav yog.
Kauj Ruam 5. Nrhiav koj li teev lossis txhua xyoo kilowatt teev
Cov kilowatt teev tso tawm ntawm lub ntsuas cua yog qhov ua haujlwm tag nrho los ntawm lub sijhawm uas lub cuab yeej txuas rau. Koj tuaj yeem muab tus lej no los kwv yees koj lub kWh nyob rau lub sijhawm ntev dua.
Piv txwv, cia peb hais tias lub ntsuas cua tau ua haujlwm li 5 hnub, thiab koj xav pom qhov kwv yees li 30-hnub. 30 faib los ntawm 5 yog 6, yog li sib npaug kWh tso tawm los ntawm 6
Lub tswv yim
- Yog tias daim ntawv lo tsis teev cov watts, xyuas tus tswv phau ntawv. Ntau daim ntawv niaj hnub ua haujlwm rau koj, suav nrog cov ntawv EnergyGuide daj hauv Asmeskas, thiab cov ntawv xiav thiab dawb hauv EU. Saib rau kilowatt teev teev ua "kWh/xyoo," "kWh/xyoo" (xyoo), lossis "kWh/60 feeb." Cov no yog los ntawm kev siv tsev neeg ib txwm muaj, uas feem ntau yog qhov tseeb ntau dua li cov lus suav hauv qab no.
- Qee lub cuab yeej muaj ntau lub zog teeb tsa. Lawv cov ntawv tuaj yeem teev cov ntaub ntawv cais rau txhua qhov chaw, lossis tsuas yog qhov siab tshaj plaws.
