摘　　要：本文以热经济学结构理论为基础,针对采用燃气内燃机发电、吸附制冷机提供冷量的微型冷热电联供系统,建立了基于燃料-产品定义的热经济学模型,量化了系统内各设备间的生产交互关系.根据实验结果,利用(火用)成本分析方法评价了系统在冷电设计工况以及变工况下的生产性能.结果不仅反映出热经济学结构理论是一种强有力的评价复杂系统性能的工具,而且证明吸附制冷机高效利用了系统中的低温余热.In this paper, a thermoeconomic model based on Fuel-Product concept of Structural Theory is defined to quantify the productive interaction between different components for a gas-fired micro combined cooling, heating and power （CCHP） system, which uses a small-scale generator set driven by a gas engine and an adsorption chiller. By adopting the exergy cost analysis method, the production performance of components at design and variable conditions of combined cooling and power are evaluated according to the experimental data. The results not only reflect that the Structural Theory is a powerful tool, but also prove that the adoption chiller utilizes the low temperature waste heat of the micro-CCHP system efficiently.
