Summary

Fin-tube heat exchangers (FTHX) are a key component in heating, ventilation, and air conditioning systems, and enhancing their performance is essential for improving energy efficiency. While numerous studies have explored methods to improve FTHXs performance, the impact of splitter placement appears to not have been thoroughly investigated in open literature. In this study, the effects of applying two splitter designs (beginning-circuit split and end-circuit split) on the performance of a FTHX evaporator coil were investigated. The results show that among the baseline heat exchanger (HX), end-circuit split, and beginning-circuit split designs, the baseline HX exhibits the highest values of cooling capacity and pressure drop. Moreover, the end-circuit split design shows the closest values to the baseline HX, with cooling capacity and pressure drop approximately 5-6% and 32% lower, respectively. Meanwhile, the beginning-circuit split design records the lowest values, with cooling capacity and pressure drop showing reductions of 23-25% and 83%, respectively, when compared to the baseline HX.
