Txoj Kev Them Nyiaj Rov Qab

 

Cov chaw soj ntsuam kev hloov kho LED yuav tsum suav lawv cov nyiaj them rov qab tshwj xeeb siv cov qauv no:

Kauj ruam 1: Txiav txim siab tus nqi hluav taws xob txhua xyoo tam sim no

Tam sim no fixture wattage × fixture suav × txhua xyoo ua hauj lwm teev ÷ 1,000 × hluav taws xob tus nqi=txhua xyoo kWh nqi

Kauj ruam 2: Xam cov nqi hluav taws xob txhua xyoo LED

LED fixture wattage × fixture suav × txhua xyoo ua hauj lwm teev ÷ 1,000 × hluav taws xob tus nqi=LED kWh nqi

Kauj ruam 3: Txiav txim siab kev txuag hluav taws xob txhua xyoo

Kauj Ruam 1 tau tshem tawm Kauj Ruam 2 tshwm sim=kev txuag hluav taws xob txhua xyoo

Kauj ruam 4: Xam suav nyiaj txij nkawm txhua xyoo

(Tam sim no lub teeb lifespan nyob rau hauv cov xuab moos ÷ txhua xyoo ua hauj lwm teev) × (cov nqi teeb + nqi zog) × fixture suav=kev tu txhua xyoo tam sim no

Tus nqi kho LED (feem ntau yog $0 rau thawj 10 xyoo)=$0

Kev tu txhua xyoo tam sim no rho tawm LED txij nkawm=kev txuag nyiaj txhua xyoo

Kauj ruam 5: Xam tag nrho qhov project tus nqi

(LED fixture nqi + installation nqi) × fixture suav=tag nrho cov nqi project

Tus nqi tag nrho qhov project rho tawm cov nyiaj rov qab=net project cost

Kauj ruam 6: Txheeb xyuas lub sijhawm them rov qab

Net project tus nqi ÷ (kev txuag hluav taws xob txhua xyoo + kev txuag nyiaj txhua xyoo)=them rov qab hauv xyoo

Ib qho piv txwv 100-fixture office: 90W fluorescents → 40W LEDs, 2,500 teev txhua xyoo, hluav taws xob $ 0.12 / kWh, $ 40 / fixture installation nqi, $ 30 rebate / fixture:

Lub zog tam sim no: 90W × 100 × 2,500 ÷ 1,000 × $ 0.12=$ 2,700 / xyoo

LED lub zog: 40W × 100 × 2,500 ÷ 1,000 × $ 0.12=$ 1,200 / xyoo

Kev txuag hluav taws xob: $ 1,500 / xyoo

Kev txuag nyiaj: $ 1,000 / xyoo (kwv yees)

Tag nrho cov nyiaj khaws cia: $ 2,500 / xyoo

Tus nqi ntawm qhov project: ($120 + $40) × 100 − ($30 × 100)=$13,000

Them nyiaj rov qab: $13,000 ÷ $2,500=5.2 xyoo

 

Cov txiaj ntsig zais qhov txiaj ntsig dhau qhov kev txuag ncaj qha

 

Ntau qhov kev txo nqi tsis ncaj feem ntau mus rau qhov tsis muaj nuj nqis hauv kev suav nyiaj rov qab yooj yim:

Txo cov nqi pov hwm hluav taws kub: LED vaj huam sib luag tsim 80% cua sov tsawg dua fluorescent lossis HID fixtures, txo cov hluav taws kub. Qee lub tuam txhab tuav pov hwm txo cov nqi them los ntawm 2-5% rau cov chaw uas muaj txhua yam-LED teeb pom kev zoo, tshwj xeeb tshaj yog nyob rau hauv warehouses khaws cov khoom tawg.

Txhim kho kev ntsuas kev tsim khoom: Lub Chaw Tshawb Fawb Teeb pom kev zoo pom tias cov xim zoo tshaj plaws thiab txo qis flicker hauv cov tshuab LED cuam tshuam nrog 3-8% kev tsim khoom tau txais txiaj ntsig hauv kev sib dhos thiab tshuaj xyuas cov haujlwm. Rau 50 tus neeg ua haujlwm qhov chaw nrog cov nyiaj hli nruab nrab ntawm $ 50,000, txawm tias qhov nce 3% txhais tau tias yog $ 75,000 hauv tus nqi txhua xyoo.

Txo cov nqi pov tseg: Fluorescent raj muaj mercury thiab yuav tsum tau tshwj xeeb cov pov tseg pov tseg ntawm $ 1-3 ib lub raj. Ib qho chaw hloov 500 lub raj txhua 3 xyoos txuag tau $ 1,500-4,500 ib lub voj voog hauv cov nqi pov tseg thiab kev tswj hwm nyiaj siv ua haujlwm.

Cov khoom depreciation: LED fixtures feem ntau tsim nyog rau lub sij hawm luv luv luv nqi raws li IRS Tshooj 179, tso cai rau kev txiav tawm tam sim ntawd tsis yog ntau - xyoo depreciation. Cov txiaj ntsig ntawm lub sijhawm no txhim kho cov nyiaj ntsuab ntws rau cov se- cov chaw them nyiaj.

 

Thaum LED hloov kho kom tsawg dua kev lag luam

 

Txawm hais tias muaj kev lag luam muaj zog hauv ntau qhov xwm txheej, qee qhov xwm txheej ua rau ncua kev siv sijhawm:

Tsawg- thaj chaw siv: Chav tsev cia khoom, chaw kho tshuab, thiab lwm qhov chaw siv tsawg dua 500 teev ib xyoos twg yuav xav tau 10+ xyoo rau kev them rov qab. Tshwj tsis yog cov khoom siv uas twb muaj lawm xav tau hloov pauv lawm, cov no yuav tsum yog qhov tseem ceeb dua.

Cov khoom siv nrog kev hloov kho teeb pom kev tsis ntev los no: Cov tsev uas txhim kho T8 los yog T5 fluorescent systems nyob rau hauv 3 lub xyoo dhau los -5 xyoo yuav tsis pom kev txuag nyiaj ntau. Tos kom txog thaum cov kab ke mus txog qhov kawg -ntawm-lub neej ua kom muaj kev lag luam loj tshaj plaws.

Cov chaw ib ntus: Kev tsim kho cov tsheb thauj khoom, qhov chaw ua yeeb yam ib ntus, thiab luv luv- cov neeg xauj tsev yuav tsis ua haujlwm ntev txaus kom paub txog kev them rov qab, tshwj xeeb tshaj yog tias cov khoom siv yuav tsum tau muab tshem tawm thaum tsiv tawm - tawm.

Cov nqi hluav taws xob tsawg heev: Ib txhais tes ntawm cov nroog uas muaj hluav taws xob hluav taws xob lossis cov nyiaj siv hluav taws xob hnyav muaj cov nqi qis dua $ 0.06 / kWh. Txawm hais tias kev hloov kho LED tseem ua rau muaj txiaj ntsig zoo ROI, 5-7 xyoo kev them nyiaj rov qab yuav tsis ua raws li cov neeg lag luam teeb meem piv rau lwm txoj kev nqis peev.
