Résumé
A public domain finned-tube heat exchanger simulation program, EVAP-COND ver. 3.0, has been equipped with an evolutionary algorithm-based module, called ISHED – intelligent system for heat exchanger design, which facilitates optimization of refrigerant circuitry. Previous studies demonstrated that the best circuitry designs developed by the evolutionary methods in ISHED yielded capacity improvements over the original manufacturers’ designs. Since evolutionary methods inherently involve the element of randomness, they do not guarantee achieving the optimum outcome within a given optimization run. This paper presents optimization experiments with ISHED and provides recommendations for selecting optional run parameters to expedite convergence to the optimal circuitry designs. This paper also presents the implementation of a design constraint which forces all tube connections on one side of the heat exchanger to be short return bends between two neighboring tubes; i.e., each connected pair of tubes resembles a large “hairpin”, and evaluates this design constraint’s influence on the optimization process.
