摘　　要：本文以商业楼为例,模拟计算微燃机和内燃机驱动的无蓄能及蓄能型联产系统的一次能源利用率、相对节能率、初投资及运行费用,对系统的热力学和经济性能进行评价分析。结果表明,联产系统的一次能耗均少于分产系统,其年生命周期成本则高于分产系统。考虑能耗和经济性,该商业楼应选择内燃机为原动机。分析表明,增加蓄能装置可明显提高联产系统的能耗及经济性能,同时存在最优蓄能容量可使联产系统达到性能最佳。The energy and economic performance of combined cooling, heating and power （CCHP） system with and without TES in the commercial building were evaluated by simulating the primary energy ratio, primary energy saving ratio, capital cost and operation cost. The results showed that the primary energy consumptions of CCHP systems were lower than the separate production system, while their annualized life cycle costs were higher than that. Hence, with the consideration about energy consumption and economic benefit, the gas engine should be used as the prime mover in the CCHP in the building. It could be concluded that the introduction of TES could improve the energy and economic performance of CCHP system, and the optimal capacity of TES would improve the performance of CCHP system to the best.
