Abstract: In the context of increasing awareness of climate change, the performance and environmental impacts (EIs) of heat exchangers (HEs) have become crucial. Traditional approaches have often overlooked the comprehensive evaluation of EI due to the absence of a universal criterion. Adressing this gap, this study introduces an innovative methodology for assessing both performance and EI in HEs, focusing on heat transfer and pressure drop across various types. The proposed methodology leverages exergoenvironmental analysis to optimize HEs handling liquid and gaseous fluids on both hot and cold sides with pumps and fans. Validation of this approach is conducted using experimental data from compact plate HEs (CPHEs) produced by additive manufacturing. The results highlight the influence of material choice on the EI of CPHEs, with a particular emphasis on the comparative significance of exergy destruction-related EI versus component-related EI. Notably, the EI on the cold side is consistently higher than that on the hot side. The study also delves into the role of pressure drop as a critical factor in HE enhancement techniques and discusses the variations in EI under different ambient conditions, inlet temperatures, and pressures. Consequently, this study presents a powerful model that serves as both an EI criterian and an optimization tool for HEs, offering valuable insights for environmentally conscious improvements in HE design and operation.
