摘要
基于热力学第二定律的分析方法,按照能质系数的概念确定了电、天然气、煤、蒸汽、热水等各种形式的建筑用能及建筑物耗冷量、耗热量的能源品位高低;提出了一种评价能源利用方式的新方法。该方法利用能量转换系数(ecc/ECC)指标,可对包括园区热电冷联供系统、建筑物制冷供热系统、能量输配系统及末端用能设备在内的一系列用能环节的能源利用效率进行评价,作为确定建筑物用能方式的决策依据。
Using the exergy analysis method, the conception of energy quality character was presented, which indicated the discretion of electricity, gas, coal, steam and hot water, cooling or heating load etc. Based on the energy quality character, one new assessment method named ECC （energy conversion coeffcient） for the energy utilization manner was introduced for the scheme decision-making of the district BCHP system, building cooling and heating system and energy transportation and distribution system and various energy consumption machine.3
