Abstract

An experimental study was undertaken to evaluate the thermal performance of a novel compact latent heat thermal energy storage (LH-TES) system. The heat exchanger immersed in the phase change material (PCM) CrodaTherm™ 53, enclosed in a cuboid shaped metal container was a Multi-Plate Heat Exchanger (MPHX). The heat exchanger in the thermal store was comprised of ten individual aluminium rectangular plates mounted vertically spaced at 30 mm intervals. The heat exchanger plates were connected in a parallel flow arrangement with two manifolds used to divide the flow equally between plates. During the charging process, a peak thermal input power of 4.2 kW was measured for an Heat Transfer Fluid (HTF) inlet temperature of 70 ℃. To characterize the effect of HTF flow rate on the discharging process, experiments were performed with HTF an inlet temperature of 30 ℃ with volume flow rates of 2, 3, 4, 5 and 6 L/min. Temperatures within the store at different locations were measured and instantaneous heat output rates and cumulative heat output calculated. Based on the experimental results by adjusting the HTF inlet volume flow rate during the discharging process, the output thermal power and temperature can be controlled for domestic space and water heating applications.
