摘要
研究了蒸汽系统的能效评估方法。首先以热力学第一、第二定律为依据建立了蒸汽系统能效评估体系,其次根据能量平衡和质量平衡的原理进行了蒸汽系统建模,最后给出了能效指标的计算方法并使用Visual studio 2008开发了蒸汽系统能效评估软件。结果分析表明本软件能够较为准确地建立蒸汽系统的模型并计算出能效指标,对蒸汽系统节能评估工作具有较高的实用价值。
In this paper, the energy efficiency assessment method is studied. Firstly, the energy efficien- cy assessment system of steam system is established based on the first and second law of thermodynamics. Secondly, the model of steam system is build up based on the principle of energy and mass conservation. Finally, the calculation method of the indexes is given and an assessment software is developed. Test re- sult shows that the software can build up a relatively accurate steam system model and calculate the effi- ciency indexes, which has high practical value in energy assessment of steam system_
