读音 英 [ˈekzədʒi ɪˈfɪʃnsi];美 [ˈekzərdʒi ɪˈfɪʃnsi] 意思 “exergy efficiency”意为“火用效率” ,是衡量能量系统有效利用程度的一个重要指标。

“火用”(exergy)是指在一定环境条件下,能量中可以转化为有用功的最大份额。

火用效率反映了系统将输入的可用能转化为期望输出的可用能的比例,数值越高说明系统对能量的有效利用程度越高。

网络释义 在能源、动力工程、热力学等专业领域的文献、学术研究、行业报告以及相关专业论坛中频繁出现。

用于评估各种能源转换设备(如发动机、制冷机、热力发电厂等)、能源系统(如区域供热系统、工业生产流程中的能源利用环节等)的性能优劣,是能源领域研究节能减排、提高能源利用效率的关键参数之一。

常用搭配短语 “thermal exergy efficiency”(热火用效率) “overall exergy efficiency”(总火用效率) “improve exergy efficiency”(提高火用效率) “calculate exergy efficiency”(计算火用效率) 造句 The exergy efficiency of this new energy system is much higher than that of the old one.(这个新能源系统的火用效率比旧系统高得多。)
