MVR evaporator zog txuag cov nyhuv

Lub MVR evaporator compresses qhov ntsuas kub tsawg ntawm chav los ntawm MVR compressor, qhov kub thiab siab nce siab, lub enthalpy nce, thiab tom qab ntawd nkag mus rau hauv cov cua kub kom ua kom tau txais qhov ua kom zoo siv cov latent tshav kub ntawm lub zog. Tsuas yog pib, tsis muaj lub tshuab tsim hluav taws xob tsim nyog thaum tag nrho cov txheej txheem evaporation.

Nyob rau hauv cov txheej txheem muaj txiaj ntsig evaporation, qhov nqus theem ob ntawm ib qho ntawm cov evaporator tsis tuaj yeem siv ncaj qha raws li cov cua kub ntawm cov txiaj ntsig no, thiab tsuas yog siv tau ua cov khoom cua kub ntawm cov nyhuv thib ob lossis ntau cov cuam tshuam. Yog tias nws siv los ua cov cuab yeej siv hluav taws xob zoo, nws yuav tsum tau txais lub zog ntxiv kom nws qhov kub (siab). Lub dav hlau dej twj tso kua mis tsuas yog tuaj yeem nyem ib feem ntawm qhov nqus theem ob, thiab MVR evaporator tuaj yeem rov qab siv txhua cov theem nrab hauv cov evaporator

1. Thaum 111.3 degrees, cov cua kub uas yuav tsum tau yaj 1 kg dej yog (raws li cov dej kub ntawm 111.3 degrees pib ua kom sov thiab ua 111.3 degrees ntawm cov kua dej).

2693.4 - 417.51 = 2275.89kj / kg

Kev ua haujlwm compression (1.0 bar rau 1.5 bar) yuav tsum muaj rau qhov zoo tagnrho compression yog:

Ws = (2693.4-2675.4) = 18 kj / kg

Noj lub compressor txhua yam efficiency 65%

Siv lub compressor thermal efficiency 25%

Kev ua haujlwm tiav qhov yuav tsum tau ua los ntawm qhov tseeb MVR compressor compressor = ws / 0.65 / 0.25 = 110kj / kg

3.Performance ratio = 2275/110 = 20.68

Lub ntsiab lus ntawm MVR evaporator lub zog noj tau sib npaug rau 20 teebmeem
