While small diameter (≤5 mm) tube-fin heat exchangers have the potential to improve
performance, successful designs must meet many criteria. Three case studies are presented
to illustrate how optimization techniques can be used to design drop-in 5mm tube-fin
condenser replacements for a domestic refrigerator, a packaged terminal air conditioner, and a window
air conditioner that meet engineering and economic objectives. An optimization method is
applied to heat exchanger simulation tools to evaluate the performance of heat exchanger
simulations to identify optimal configurations that meet many objectives. Results
indicate that these designs can significantly enhance energy-efficiency, reduce
refrigerant charge, and reduce material consumption and cost.
