Performance analysis of a stand-alone thermal energy storage system based on CSM plates filled with phase change material

In this study, experimental investigations on a Phase Change Material (PCM) based thermal energy storage system (TES) were carried out. The TES was designed and tested as first step of developing potential product which can be integrated with commercially available ventilation (VEX308) to provide cold intake air for space cooling applications. consisted wedge-shaped flow regions before after an array Compact Storage Module (CSM) plates filled PCM arranged vertically gaps between the plates. Two design configurations investigated gap size (1.5 mm 3 mm) in order compare them pressure loss through performance storage. Investigations done at two rates 400 m3/h 800 within working range VEX308 fixed inlet temperatures 27 °C 13 heating cycles storage, respectively. ranges chosen investigate application during summer season Denmark. Parameters were: system, distribution from top bottom stack, temperature bottom, melting solidification PCM. Results showed that drop both configurations, well desired limits (<180Pa) successful integration VEX308. Temperature relatively fair stack indicating adequate manifold design. 1.5 configuration (55 CSM 110 kg PCM) faster compared (50 100 PCM). Both systems almost same efficiency (78.3%) utilization provided approximately 8.7% more than because presence 10 extra
