Power and cooling cogeneration system using organic Rankine cycle (ORC) and adsorption system can make a better utilization of low grade heat. A thermally driven cooling and power cogeneration system with dual working mode was proposed for application cases with/without cooling demand. In the cogeneration mode

power and cooling is yielded by ORC and adsorption systems

respectively. In the power-only generation mode

cooler of ORC system is cooled by the output chilled water of adsorption system so that working fluid condensation temperature of ORC system is lower and more power generation is obtained. A mathematical model was built and the system performance was numerically studied and analyzed. The simulation results show this ORC-adsorption system with dual working mode has better performance than solo ORC

adsorption and traditional ORC-adsorption systems

especially under the conditions of high hot water temperature.
