A solar-assisted biomass-based tri-generation system is suggested to provide domestic energy demands and studied from the perspectives of thermodynamics and sustainability. In the proposed combined system, gas and steam turbines are considered as the main power generation systems, while the chiller and an auxiliary heat exchanger exploit the thermal energy content of the effluent. A pressurized water circuit is also considered to harvest the waste heat from the employed steam cycle condenser and concentrated photovoltaic to feed the desired space heating. The main components of the integrated system are assessed exergetically to show the main exergy destructive units. The influence on the performance of the system of some decision parameters and summer/winter conditions as well is investigated. Results showed that the designed system is capable to feed 1241 kW space heating, 101.5 kW domestic hot water and 55.35 kW chilled water as space cooling, besides delivering 1MWe power. It is revealed that the pressure ratio of the air compressor leads to the system performance optimizing while the performance of the system has a linear relation with two variables of the gas turbine inlet temperature and cold end temperature difference within the air heater.

从热力学和可持续性的角度研究了太阳能辅助的基于生物质的三联产系统来满足国内能源需求。在提议的联合系统中，燃气轮机和蒸汽轮机被认为是主要的发电系统，而冷却器和辅助热交换器则利用了流出物的热能含量。加压水回路也被认为是从所用的蒸汽循环冷凝器和集中光伏收集废热，以供给所需的空间加热。对集成系统的主要组件进行评估，以显示主要的火用破坏单元。研究了一些决策参数和夏季/冬季条件对系统性能的影响。结果表明，设计的系统除了提供 1MWe 的功率外，还能够提供 1241 kW 的空间供暖、101.5 kW 的生活热水和 55.35 kW 的冷冻水作为空间冷却。结果表明，空压机压比导致系统性能优化，而系统性能与燃气轮机入口温度和空气加热器冷端温差两个变量呈线性关系。
