中文摘要：

研究了以燃气内燃机、燃气锅炉、换热器、吸收式制冷机和压缩式制冷机为主要设备的冷热电联供系统。以满足年度费用最低为优化目标,建立了联供系统的经济优化模型,并以建筑物全年冷、热、电负荷需求作为计算基础,得出了系统优化配置和运行策略。

英文摘要：

Combined Cooling,Heating and Power（CCHP） system with a core of a gas engine,a gas boiler,a heat exchanger,an absorption chiller and a electric chiller was analyzed from the optimal operation point of view.By taking the minimal cost meeting the annual load demand of cooling,heating and power as optimizing function,the economic optimization model of the CCHP system was established.The optimal scheme and operation strategy of the system was obtained with real projects.
