摘要
导出了管壳式换热器的火用损率计算公式 ,对影响功火用损的因素进行了分析。利用火用损比 Ne对比分析了逆流、并流及错流换热器的热力学性能 。
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.
