Heat Transfer Peerformance Research of Honeycomb Ceramic Thermal Energy Storage
Abstract
Thermal energy storage (TES) is core advantage for the concentrated solar power (CSP) technologies. A packed bed of rocks or other ceramic is especially suitable when gas is used as the heat transfer fluid. The heat transfer performance of thermal energy storage (TES) device which use the air as the heat transfer fluid and the honeycomb ceramic as the storage material was researched by experimental in this paper. The results showed that the temperature distribution was obvious thermocline distribution when charging and discharging process. The charging efficiency of the TES device was higher than 75%, and the discharging efficiency was higher than 85%.
