Abstract. In this paper, the exergy loses of the heat exchanger
network, designed by Pinch method, is analised. On analitical way, the
exergy changes and the exergy loses is defined, as in standalone heat exchanger,
also in heat exchanger network. The result of this work is the fact that
heat exchangers network, generated by pinch design rules and plus/minus
principle, is the solution with best performance according to minimum exergy
loses.
Key words: Pinch desighn method, heat exchanger network, exergy
loses.
INTEGRACIJA PROCESA – EXERGIJSKI
GUBICI MREŽE RAZMENJIVAČA TOPLOTE
U radu je data analiza eksergijskih gubitaka mreže razmenjivača toplote
koja se generiše upotrebom Pinč metode. Analitičkim putem definisani su
eksergijski gubici strujnih tokova kako u izolovanom razmenjivaču toplote,
tako i u mreži razmenjivača toplote. Rezultat rada je činjenica da je mreža
razmenjivača toplote generisana putem pinč metode ujedno i mreža sa minimalnim
eksergijskim gubicima
Ključne reči: Pinč metoda, mreža razmenjivača toplote, eksergijski
gubici.
