Summary

The integration of microchannel heat exchangers (MCHEs) with phase change materials (PCMs) presents a promising approach for improving energy efficiency and thermal management in space heating systems, due to their high surface area-to-volume ratio, compact design, faster PCM charging, and higher energy density. Correspondingly, a purpose-designed MCHE was fabricated, utilizing airflow as the heat transfer fluid (HTF), and incorporating organic PCM A27 within microchannels. A series of experiments were carried out to study the thermal performance of the MCHE throughout PCM charging and discharging processes at different operating conditions. Furthermore, a validated Computational fluid dynamics (CFD) model was developed to optimize the thermal storage performance at various operating and design conditions. The integration of advanced heat exchangers with energy-efficient thermal storage materials holds significant potential to enhance building heating technologies, offering improved energy efficiency, faster thermal response, and
greater sustainability.
