he vast volumes of waste heat rejected from industrial processes can be converted into electricity and useful heat through advanced energy conversation technologies. In this project, a test rig of a small-scale power generation (up to 5kW) and heat recovery system will be established with a heat source temperature between 100 ^C and 500 ^C, which is representative of actual industrial waste heat. The natural refrigerant CO2 will be engaged as a working fluid in the system, considering its excellent thermophysical properties and negligible environmental impact. Corresponding to the large temperature range of the heat source, the CO2 supercritical Rankine cycle will be applied for temperatures below 350 ^C, otherwise, combined CO2 Brayton and supercritical Rankine cycles will be employed. Simultaneously, a detailed mathematical model for the proposed system will be developed and validated with measurements. The model will then evaluate, compare and analyse different system and component designs, heat recovery potentials and control optimisations which will eventually lead to optimal design and construction of the proposed system.

工业过程中产生的大量废热可以通过先进的能量转换技术转化为电能和有用的热量。本项目将建立小型发电（最大5kW）及热回收系统试验台，热源温度在100 ~ 500℃之间，代表实际工业余热。考虑到其优异的热物理性能和可忽略的环境影响，天然制冷剂CO2将作为系统中的工作流体。由于热源温度范围大，在350°C以下采用CO2超临界朗肯循环，否则采用CO2布雷顿循环和超临界朗肯循环相结合的方式。同时，将为所建议的系统建立一个详细的数学模型，并通过测量进行验证。然后，该模型将评估、比较和分析不同的系统和组件设计、热回收潜力和控制优化，这将最终导致所提议系统的最佳设计和构造。
