✦ Synopsis

Advantage is taken of an unused potential which lies in the evolutionary development method for heat exchanger networks (HEN) proposed by Linnhoff and Flower to construct an algorithm which reduces recursively the number of units of a given HEN problem. As a result, all networks are generated that fulfill the heating and cooling requirements of the problem and whose number of units cannot be further reduced. Among the solutions obtained, those are selected which satisfy the condition of minimum permissible temperature driving force. A C++ implementation of the algorithm has been applied to a number of problems taken from the literature.

## Abstract In this paper a thermal network method using the effective specific heat model of a refrigerant with phase change is proposed for predicting the capacity of a plate‐fin and tube‐type heat exchanger. The effective specific heat model can attain an accurate result of a condenser's heat ex
