Tus nqi luam yog qhov tseem ceeb rau cov tswv lag luam luam tawm thaum lawv cov nuj nqis rau lawv cov nyiaj tau los tiv thaiv lawv cov nyiaj tau los ntawm lawv cov nyiaj tau los ntawm cov tswv yim kev lag luam thiab hloov kho cov haujlwm. UV luam ntawv tau dav yog qhov ua tau zoo rau nws cov nqi-ua tau zoo, nrog qee cov ntawv tshaj tawm pom zoo cov nqi qis li $ 0.2 ib square Meter. Tab sis dab tsi yog dab neeg tiag tiag tom qab cov lej no? Cia peb tawg nws.
Dab tsi ua tau tus nqi luam tawm?
- Mem
- Kev luam ntawv: Noj nyob rau hauv kis tus nqi ntawm $ 69 toj ib liter, muaj peev xwm ntawm kev npog nruab nrab ntawm 70-100 square metres. Qhov no tau teeb tsa tus lej hauv kev siv nyiaj ntawm kwv yees li $ 0.69 rau $ 0.98 rau txhua lub ntsuas square.
- Rau kev saib xyuas: Nrog ob daim ntawv luam tawm, tus qauv kev ntxuav siv cov kwv yees li 4ml ib lub taub hau. Qhov nruab nrab ob txoj phuam huv ib nrab ntawm meter meter, tus lej nqi rau kev hloov kho yog ib puag ncig yog $ 0.4 ib square. Qhov no coj tag nrho cov mem kua nqi rau ib square meter rau qhov chaw ntawm $ 1.19 thiab $ 1.38.
- Fai fab
- Kev siv: Xav txogTus UV Tshuab Luam Ntawv Ntawm Nruab Nrab 6090 LojSiv 800 watts toj ib teev. Nrog US nruab nrab nruab nrab hluav taws xob tus nqi ntawm 16.21 xees rau ib lub kilowatt-teev, cia ua haujlwm ntawm lub zog tag nrho rau 8 teev (cov kabmob (cov neeg tshuab luam ntawv tsis sib xws).
- Kev suav:
- Zog siv rau 8 teev: 0.8 KW × 8 teev = 6.4 kWh
- Tus nqi rau 8 teev: 6.4 Kwh × $ 0.1621 / kWh = $ 1.03744
- Tag Nrho Square Meters Luam tawm hauv 8 teev: 2 square metres / teev × 8 teev = 16 square metres
- Nqi rau ib square Meter: $ 1.03744 / 16 square metres = $ 0.06484
Yog li, cov kwv yees luam ntawv them nqi ib square Meter hloov tawm los ntawm $ 1.25 thiab $ 1.44.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov kev kwv yees no yuav tsis siv rau txhua lub tshuab. Cov tshuab luam ntawv loj feem ntau muaj cov nqi qis rau ib lub meter meter rau kev siv thiab luam loj dua thiab cov nplai kev ntsuas kom txo cov nqi. Ntxiv rau, cov nqi luam tawm tsuas yog ib feem ntawm tag nrho cov cai nqi, nrog lwm cov nuj nqis uas zoo li kev ua haujlwm thiab cov nqi xauj tsev ntau dua.
Muaj cov qauv lag luam muaj zog uas ua kom cov xaj xaj tuaj rau hauv cov tsis tu ncua ntau qhov tseem ceeb tshaj li tsuas khaws cov nqi luam ntawv qis. Thiab pom daim duab ntawm $ 1.25 rau $ 1.44 ib square meter pab qhia yog vim li cas cov luam ntawv UV tsis plam pw tsaug zog tshaj cov nqi luam tawm.
Peb cia siab tias daim ntawv no tau muab kev nkag siab zoo ntawm UV cov nqi luam ntawv. Yog koj tshawb nrhiavib tug nyob tau UV tshuab luam ntawv, Xav tias yuav rov qab los xauj peb xaiv thiab tham nrog peb cov kws tshaj lij rau cov lus sib sau raug.
