Development of SrBr2 composite sorbents for a sorption thermal energy storage system to store low-temperature heat

An lab-scale sorption TES system with 1 kWh design capacity was established and investigated. Under the conditions in winter seasons: charging temperature Tcha is 80 °C, discharging temperature Tdis is 35 °C, condensing temperature Tc is 15 °C, evaporating temperature Te is 15 °C, the heat storage capacity can reach 1.02 kWh. The heat storage density obtained is 242 Wh/kg composite sorbent and the heat discharging power is 67.4 kW/m3 composite sorbent.
