Abstract Environmental and economic factors are among the most important in thermodynamic systems design. To evaluate energy production systems from economic an environmental viewpoints, exergoeconomic and exergoenvironmental analyses are sometimes used. In this research, the concept of emergy is used for economic and environmental studies to improve understanding. Emergy expresses all the inputs and outputs of a system based on a specific type of energy (usually solar energy) that is required to generate the input or output. In order to enhance energy-based emergy, it is converted to exergy-based emergy here and, using the specific exergy costing (SPECO) method, emergy-based exergoeconomic and emergy-based exergoenvironmental balances are written for the components of a system. The present economic and environmental assessment based on emergy is carried out on a combined flash and binary geothermal system. The results of this study show that the economic emergy factor and the ecological emergy factor of the system are 34.1% and 4%, respectively. Therefore, to reduce the amount of destruction emergy, strategies must be adopted.

使用地热发电厂的能值进行经济和环境评估

摘要 环境和经济因素是热力学系统设计中最重要的因素之一。为了从经济和环境的角度评估能源生产系统，有时会使用 exergoeconomic 和 exergoenvironment 分析。在这项研究中，能值的概念被用于经济和环境研究，以提高理解。能值表示基于产生输入或输出所需的特定类型的能量（通常是太阳能）的系统的所有输入和输出。为了增强基于能量的能值，这里将其转换为基于火用的能值，并使用特定火用成本 (SPECO) 方法，为系统的组件编写基于能值的 exergoeconomic 和基于 emergy 的 exergoenvironmental 平衡。目前基于能值的经济和环境评估是在组合闪蒸和二元地热系统上进行的。本研究结果表明，该系统的经济能值因子和生态能值因子分别为34.1%和4%。因此，为了减少破坏能值，必须采取策略。
