Yuav ua li cas koj xam lub hwj chim noj ntawm lub raj teeb?

Yog tias koj xav paub ntau npaum li cas hluav taws xob koj lub teeb lub raj siv, ntawm no yog cov lus qhia ceev los pab koj xam koj lub zog noj.
1. Txheeb xyuas qhov ntsuas wattage ntawm lub teeb lub raj. Qhov no feem ntau yuav luam tawm ntawm lub raj nws tus kheej lossis ntawm lub ntim uas nws tuaj. Piv txwv li, 40-watt tube teeb yuav siv 40 watts ntawm lub zog txhua teev nws tau qhib.
2. Kwv yees pes tsawg teev nyob rau ib hnub twg lub teeb lub raj siv. Yog tias lub teeb lub raj tsuas yog siv rau ob peb teev nyob rau ib hnub, ces qhov kev siv hluav taws xob yuav qis dua yog tias nws siv li ob peb teev.
3. Xam tag nrho cov kev siv hluav taws xob ib hnub. Ua li no, muab cov wattage ntawm lub teeb lub teeb los ntawm cov sij hawm uas nws siv. Piv txwv li, yog tias koj muaj 40-watt tube teeb uas siv rau 4 teev hauv ib hnub, ces tag nrho lub zog siv yuav yog 40 x 4=160 watt-teev ib hnub.
4. Hloov watt-teev mus kilowatt-teev (kWh). Cov tuam txhab siv hluav taws xob feem ntau them nqi rau cov neeg siv khoom raws li kilowatt-teev, yog li nws muaj txiaj ntsig los suav koj lub zog siv hauv kWh yog li koj tuaj yeem sib piv rau koj daim nqi hluav taws xob. Hloov watt-teev mus rau kWh, faib los ntawm 1, 000. Ntxiv nrog rau qhov piv txwv saum toj no, 160 watt-teev ib hnub yog 0.16 kWh ib hnub.
5. Xam qhov kev siv hluav taws xob txhua hli. Muab cov kev siv hluav taws xob txhua hnub (hauv kWh) los ntawm cov hnub hauv ib hlis. Piv txwv li, yog tias muaj 30 hnub hauv ib lub hlis, ces qhov kev siv hluav taws xob txhua hli rau lub teeb lub teeb uas siv 0.16 kWh ib hnub twg yuav yog 4.8 kWh ib hlis.
6. Kwv yees tus nqi. Thaum kawg, koj tuaj yeem kwv yees tus nqi khiav koj lub teeb lub teeb los ntawm kev sib npaug ntawm kev siv hluav taws xob txhua hli los ntawm tus nqi ib kWh los ntawm koj lub tuam txhab hluav taws xob. Tus nqi ib kWh yuav txawv nyob ntawm koj qhov chaw thiab koj lub tuam txhab hluav taws xob. Piv txwv li, yog tias koj lub tuam txhab nqi hluav taws xob them $0.12 ib kWh, ces tus nqi kwv yees rau kev khiav lub teeb 40-watt raj rau 4 teev ib hnub twg yuav yog $0.58 ib hli.
Los ntawm kev ua raws li cov kauj ruam no, koj tuaj yeem tau txais lub tswv yim ntxhib ntawm qhov hluav taws xob koj lub teeb lub teeb siv pes tsawg thiab nws raug nqi npaum li cas rau koj txhua lub hlis. Nco ntsoov tias lwm yam, xws li hnub nyoog thiab kev ua haujlwm ntawm koj lub teeb lub raj, tuaj yeem cuam tshuam rau kev siv hluav taws xob, yog li cov kev suav no yuav tsum tau siv raws li kev kwv yees nkaus xwb.
