摘要: Abstract This paper presents a heat exchanger prototype containing PCM material designed to provide 1 kW heating power during 2 h (i.e. energy storage of 2 kWh). The is tested in closed-loop wind tunnel, used constant airflow rates with temperature changes selected so that the allowed melt, then solidify. Temperature and air velocity measurements are achieved for eight estimated. second objective this work detailed results suitable validation numerical models. Therefore, geometry uncertainty associated measurement given. Results show enough stored exchanger, yet lower than before because use rate tests. On other hand, global behaviour rather simple, which gives confidence using simplified approach further help optimizing current prototype.
