摘　　要：采用热经济学结构理论,对由燃气内燃机发电、吸附制冷机提供冷量的微型冷热电联供系统,在恰当定义了组元燃料和产品的基础上,构建了热经济学成本模型和特征方程。根据实验结果,求解特征方程得到了发电、制冷和供热的热经济学成本。分析表明:天然气价格和吸附制冷机的初始投资是影响产品成本的两大因素。In this paper,a thermoeconomic cost model and characteristic equations based on the adequate fuel-product concept of structural theory are constructed for a gas-fired micro-trigeneration system,which uses a small-scale generator set driven by a gas engine and an adsorption chiller.By solving the characteristic equations,the thermoeconomic costs of power,cooling and heating are evaluated according to the experimental data.The analysis indicates that the price of natural gas and the initial investment of adsorption chiller are the main factors in determining the thermoeconomic costs of the micro-trigeneration system.
