N2 - In this study, a novel method for integrating adsorption cooling system with ORC to simultaneously generate cooling and electricity utilising low grade heat source is developed by incorporating a steam expander to the adsorption side, so that the system has two expanders in order to increase the amount of power generated. Four different configurations are developed, where in configuration 1 the adsorption system (topping cycle) is powered by an external heat source, while ORC (bottoming cycle) is driven by recovering the heat of adsorption. Configuration 2 is similar to configuration 1 but the ORC is powered using the same heating fluid leaving the adsorption side. In configuration 3, an adiabatic mixer is used to power ORC with the mixture of the leaving heating and cooling fluids, while in configuration 4; the adsorption system (bottoming cycle) is powered using the heating fluid leaving ORC (topping cycle).

Results show that using configuration 1 can achieve maximum value of the equivalent system COP of 1.17 using Silica-gel/water and R141b and 0.79 using AQSOA-ZO2/water and R141b.
