The document describes an experimental evaluation of a shell and tube heat exchanger using p-Toluidine as a phase change material (PCM). P-Toluidine has a melting temperature of 44°C and was filled in the tubes of the heat exchanger. Hot water was circulated through the shell side while cold water was passed through the tubes. The temperatures of the hot and cold water inlet and outlets were measured over time. Results showed that the effectiveness of the heat exchanger, or the maximum heat transfer, increased from 38% initially to 54% as the hot water temperature increased to 60°C and melted the PCM. The heat exchanger performance was found to improve with the PCM melting and storing thermal
