Thermal conductivity of AQSOA FAM-Z02 packed bed adsorbers in open and closed adsorption thermal energy storage systems

•Effective thermal conductivity (ETC) of packed bed adsorber is modeled for open and closed systems.•The results of ETC model show good agreement with available experimental data.•ETC charts are presented for open and closed packed bed adsorbers.•ETC is a stronger function of vapor pressure than temperature in closed systems.•The model can predict an optimum particle size for packed bed adsorber.
