In the present research, a novel solar-biomass hybrid cogeneration energy system is designed to operate in all weather condition where biomass and Direct Normal Irradiance (DNI) both are available. The proposed model integrates the Rankine cycle with an ejector and absorption refrigeration cycle, which utilized the low-temperature energy source available at the exit of the steam turbine and Heat Recovery Steam Generator (HRSG) to produce power and cooling simultaneously. The solid waste, rice husk, sugarcane bagasse and apple bagasse biomasses are used in the fluidized bed gasifier. First and second law analysis tools are used in order to assess the performance of the cogeneration energy system. The results find out the effects of some parameters on first and second law efficiencies when operated on both biomass and solar energy. The overall first and second law efficiencies of the system are found to be 42.29% and 39.72% for solid waste ranking 1 amongst all the four biomass materials respectively. A slight gain in the first and second law efficiencies 62.1% and 27.71% was observed after a considerable increase in the value of DNI at different operating conditions. The overall cycle efficiency is increasing due to cogeneration system and it is economically viable option because solar energy is freely available everywhere.

采用喷射器和单效吸收式制冷系统的太阳能-生物质热电联产发电和冷却的热力学分析

在目前的研究中，一种新型的太阳能-生物质混合热电联产能源系统被设计为在生物质和直接法向辐照度（DNI）均可用的全天候条件下运行。该模型将朗肯循环与喷射器和吸收式制冷循环集成在一起，利用蒸汽轮机和热回收蒸汽发生器（HRSG）出口处的低温能源同时产生电力和冷却。固体废物、稻壳、甘蔗渣和苹果蔗渣生物质用于流化床气化炉。使用第一定律和第二定律分析工具来评估热电联产能源系统的性能。结果发现，当使用生物质能和太阳能时，一些参数对第一定律和第二定律效率的影响。对于四种生物质材料中排名第一的固体废物，系统的整体第一定律和第二定律效率分别为 42.29% 和 39.72%。在不同操作条件下 DNI 值大幅增加后，第一定律和第二定律效率略有提高，分别为 62.1% 和 27.71%。由于热电联产系统，整体循环效率不断提高，并且由于太阳能随处可见，因此它是经济上可行的选择。
