Résumé

Manifold-microchannel technology (MMC) has displayed significant potential for outperforming contemporary heat exchangers by substantially reducing pressure drop while maintaining equivalent or superior heat transfer capacity compared to state-of-the-art (SOA) heat exchangers. This research is focused on the mathematical modeling of a manifold-microchannel heat exchanger (MMCHX) for industrial high-temperature heat pump applications using supercritical CO2 as a natural refrigerant working fluid. A dedicated numerical code was developed to compute critical parameters, including heat load, pressure drop, and outlet temperatures for the condenser and evaporator heat exchangers. The findings indicate that the adoption of MMCHX as a replacement for conventional crossflow commercial heat exchangers in high-temperature heat pump application cycles can result in a remarkable increase in volumetric heat load density for the condenser and evaporator 3.7 and 2.5 times more than the commercial ones, respectively.
