摘要	The employment of thermal energy storage (TES) system is helpful for the combined heat and power units to enhance the power load regulation capability. The energy storage density of conventional water TES tank will increase substantially when phase change material is involved. Paraffin wax is selected as PCM to fill the capsules and arranged as packed-bed inside the TES tank. The performance of repetitive charging/discharging cycles is investigated experimentally. Working conditions with different switching temperatures and flow rates are discussed to analyze their impact on the charging/discharging duration, temperature distribution and utilization rate. Results indicate that cyclic charging/discharging operation will reach stable and repetitive state after some cycles and such behavior is influenced by the switching temperatures. Increasing flow rate is able to reduce the time spent on reaching stable state while it will also lead to the decline of utilization rate. © 2019, Science Press. All right reserved.
