Various issues of increasing the thermodynamic efficiency of generation of produced energy carriers, such as water, hydrogen or compressed air are considered. The proposed technology, called multi-generation, is based on the creation of energy complexes consisting of generation facilities and consumers. The task of generation facilities is to manufacture, along with the traditional energy carriers, such as electricity and heated liquid, other produced energy carries and useful products. In the case of separate generation, they would have been generated either at consumers or at targeted enterprises.The advantages of the multi-generation technology implementation are shown for individual generation facilities and consumers, as well as for the energy supply system as a whole. The change in the specific fuel consumption for electricity and heat production is taken as a criterion for evaluating the thermodynamic efficiency for a separate generation facility. For the power supply system, the criterion is the absolute and relative changes in the exergy efficiency of generation of all produced energy carriers. Formulas for comparative calculation of efficiency for combined and separate generation at accepted evaluation criteria are derived.The accepted conditions and results of calculations of changes in the efficiency of generation of produced energy carriers at the transition from separate to combined generation for the energy complex consisting of the T-100-130 steam turbine unit combined with vapor compression and ammonia-water absorption refrigerating machines are presented.

比较电源系统的热力学效率与单独产生的和合并产生的能量载体

考虑了增加产生的能量载体例如水，氢或压缩空气的热力学效率的各种问题。所提议的技术称为多代发电，是基于创建由发电设施和用户组成的能源综合体的。发电设施的任务是与传统的能源载体（例如电和加热的液体）一起制造其他产生的能源和有用的产品。在单独发电的情况下，这些发电既可以在消费者中也可以在目标企业中产生。多代技术实施的优势对单个发电设施和消费者以及整个能源供应系统都显示出。用于发电和供热的比燃料消耗的变化被视为评估单独发电设施的热力学效率的标准。对于电源系统，标准是所有产生的能量载体产生的火用效率的绝对和相对变化。推导了按公认的评价标准对联合发电和分离发电效率进行比较计算的公式。对于由以下组成的能量复合体，从分离发电向组合发电过渡时，所产生的能量载体的发电效率变化的接受条件和计算结果如下：介绍了结合蒸汽压缩和氨水吸收式制冷机的T-100-130汽轮机单元。
