摘　　要：结合方法和热经济学原理建立了空调冷热源系统的分析模型,阐述了产品成本是评价冷热源系统方案优劣的关键因素.采用多目标模糊决策方法,综合考虑了单位产品成本、初投资、技术先进性、安装面积、运行安全可靠性、维护管理难易程度和环保性等多种影响因素,基于方法的冷热源优化决策算法.通过应用实例,说明了此新优化决策算法相比工程中传统决策方法,可靠性更高,使各决策方案间优劣区分度更加明显。An exergy analysis model of air-conditioning heating and cooling systems was established based on exergy method and thermoeconomic theory. Product exergy cost was proved to be the key factor in evaluating air-conditioning heating and cooling systems. The optimization arithmetic of air-conditioning heating and cooling systems scheme-selection, was proposed after considering the related factors, such as unit product exergy cost, capital expenditure, technology, total floor area, safety and reliability, influence on the environment and maintainability. A project example demonstrated that the proposed arithmetic was more reliable and more distinguishing, compared with the traditional methods.
