The present work reports the enhancement in free cooling potential using a modified cooling system compared to the conventional free cooling system. The proposed modified system is a novel pilot scale model packed with spherically encapsulated phase change material in a cylindrical tank along with water spray nozzles (direct evaporative cooling unit) at the inlet of the tank. The experiments were...
Thermal management performance of two composite phase change materials (PCMs)—a highly thermally conductive 60 wt% RT44HC/expanded graphite (EG) composite and a 60 wt% RT44HC/fumed silica composite with a lower thermal conductivity—is studied for a 20-cell Li-ion battery pack working at 5 and −10 °C. The temperature and voltage distributions in each battery pack are measured during single-discharge...
Thermal energy storage is a key issue in efficient energy systems applications. In this regard, phase-changing material (PCM) has been of interest as a passive solution for efficient energy management, especially in buildings. This paper presents a thermal analysis of a brick, which includes a particular type of PCM and ten air cavities, so as to be utilized in building envelop system. The objective...
Towards latent heat storage in the low-to-medium temperature range (70–250 °C), screening of sugar alcohols and their binary eutectic mixtures as potential phase change materials was carried out by focusing on the non-isothermal melting and crystallization behaviors. A preliminary screening shortened the long list of isomers from common four-carbon to six-carbon sugar alcohols to only six affordable...
