Purpose: This study aims to design an efficiency-enhancing product by considering various factors and design variables to improve the heat exchange efficiency and antibacterial performance of the heat exchange element of the ventilation system for apartment houses. Method: In this study, the structure of polystyrene sensible heat exchanger element is proposed as a single-layer curved flow path structure. In addition, the factors affecting the heat exchange performance design were investigated, and the main factors and the influence between several factors were statistically analyzed using the 6-Sigma full factorial method. Result: It was found that the material (factor A), shape (factor B), and the single length of the heat exchange air passage (factor C) play an important role in achieving the target value required to design the heat exchanger. In particular, the effectiveness levels of factor B and factor C were found to be significant at P < 0.05. It was also determined that the optimal design to achieve 90% temperature exchange efficiency is a hexagonal shape of the sensible heat element and a single air passage length of 20 cm. Considering the manufacturing error and process reliability, the final 10 products were manufactured, and their average heating temperature exchange efficiency was 89.15. Experiments on antibacterial performance showed that the Alt 2 specimen using silver nanopowder mixed materials had excellent antibacterial ability against E. coli and Staphylococcus aureus with 99.9% each.
