摘要

有机朗肯循环（ORC）与吸附式制冷结合的冷电联供系统可实现对低品位热能较好的回收利用。针对应用中存在有/无须制冷情况，提出了一种热驱动的双模式ORC-吸附式冷电联供系统，并建立数学模型进行性能对比分析。冷电联供时，ORC和吸附式系统分别输出电和冷；电力单供时，吸附式系统制出的冷水直接用于冷却ORC系统冷却器，获得更大的电输出。数值计算结果表明，与单一ORC系统、单一吸附式系统和传统单模式ORC-吸附式冷电联供系统相比，双模式ORC-吸附式冷电联供系统在可获得更佳的性能，且在高热水温度条件下，性能优势更加明显。

Abstract

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.
