Hluav taws xob hloov Efficiency
Ntau npaum li cas ntawm lwm hom hluav taws xob tuaj yeem hloov tau 10 kWh ntawm hluav taws xob? Qhov no yuav tsum muaj kev tshawb nrhiav tob dua ntawm kev hloov pauv kev sib raug zoo ntawm cov khoom siv hluav taws xob sib txawv.
Qhov txiaj ntsig hloov dua siab tshiab
Vim li cas qhov kev hloov pauv tiag tiag siab dua li tus nqi theoretical? Muaj ntau yam tseem ceeb hauv qab no. Ua ntej, muaj kev hloov hluav taws xob poob, tshwj xeeb tshaj yog nyob rau theem tsim hluav taws xob, tshwj xeeb tshaj yog cov thee - hluav taws xob hluav taws xob hluav taws xob, uas nws qhov ua tau zoo tsuas yog nyob nruab nrab ntawm 35% thiab 45%. Qhov no txhais tau hais tias ntau tshaj ib nrab ntawm lub zog yog nkim thaum lub sij hawm tsim hluav taws xob. Piv txwv li, theoretically, 10 kWh ntawm hluav taws xob tsuas yog yuav tsum tau 1.23 kg ntawm thee; Txawm li cas los xij, hauv kev ua haujlwm tiag tiag, kwv yees li 3.2 kg ntawm cov thee xav tau.
Tsis tas li ntawd, muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv sib txawv. Piv txwv li, qhov ua tau zoo ntawm lub cav roj av tsuas yog 30%, thaum lub zog ntawm lub tshuab hluav taws xob ntau tshaj 85%. Qhov no txhais tau hais tias, nyob rau hauv tib lub sijhawm, lub tsheb fais fab uas siv 10 kWh ntawm hluav taws xob tuaj yeem taug kev deb piv rau lub tsheb roj av uas siv 1.2 litres roj av (xws li tib hom tsheb).
Hauv kev ua noj ua haus, qhov ua tau zoo ntawm lub qhov cub hluav taws xob yog li 40%, thaum qhov ua tau zoo ntawm cov khoom siv hluav taws xob ua noj yog siab li 80% lossis ntau dua. Yog li ntawd, 10 kWh ntawm hluav taws xob yog sib npaug rau 2 cubic meters ntawm natural gas nyob rau hauv cov nqe lus ntawm ua noj ua haus efficiency.
