| 摘 要： | 基于热力学第二定律的分析方法,提出了能质系数的概念,给出了各种形式能源的品位高低,以此为基础提出了能源转化系统的评价指标ECC。ECC指标克服了传统初次能耗折算方法不能反映不同初次能源品位差异的不足,该指标能够在反映能源品位的基础上对能源转换系统的效率进行评价。采用ECC指标,对常用采暖空调形式进行分析评价,为采暖空调领域的冷热源设计提供理论基础。

| Abstract: | Based on the exergy analysis method, it presents the concept of energy quality coefficient to judge the energy grade, and provides Energy Conversion Coefficient (ECC) indicators to evaluate the efficiency of different energy conversion systems. ECC has overcome the deficiency of Prime Energy method. This method can evaluate the various energy conversion systems based on reflecting the grade of different primary energy. It analyzes and evaluates energy conversion systems in HVAC field by using ECC indictors, which will provide theoretical basis to the design of cooling and heating source. |
