摘要
采用[火用]分析方法对燃煤热水采暖系统和燃气热水采暖系统能耗进行评价,本文将采暖系统模块单元化,并建立了各模块单元的的[火用]分析模型,定义了[火用]效率、[火用]损率等评价标准。并对结果进行了分析,为采暖系统的节能评价、低[火用]优化提供依据。
Exergy analysis was u ed to evaluate the energy consumption for coal-fired hot water heating system and gas-fired hot water heating system.In this paper,the heating system is modularized,the exergy analysis model of each module unit is established,and the evaluation standards such as exergy efficiency and exergy loss rate are defined.The results are analyzed to provide basis for energy-saving evaluation and low cost optimization of heating system.
