| Abstract: | Equations of rate of exergy loss for shell and tube exchanger are derived. Specific of exergy loss N e is proposed to describe the thermodynamic performance of parallelflow,counterflow and two side mixed crossflow heat exchangers. Finally, several conclusions helpful for the design and choice of exchanger are proposed. |
