Abstract: A dynamic mathematical model of the plate-fin humid heat exchanger,which applies to the simulation and control of the large system,is constructed through energy and mass equations.Using numerical and lumped parameter methods,the model equations may be solved.The example results show no difference between the two methods.

Key words: exchangers, lumped parameter systems, numerical analysis
