摘　　要：研究了以燃气内燃机和吸附制冷机为核心的微型冷热电联供系统.以满足冷、热、电负荷需求时能源运行成本最低为优化目标,建立了联供系统经济最优化模型.并以应用场合负荷需求作为计算基础,得出具体的联供系统最优化运行策略.研究结果表明:联供系统具有良好的热经济性;联供系统最优化运行模式与能源价格有关,在天然气价格不变时,电价越高,联供系统运行经济性越好.A kind of micro-combined cooling, heating and power （CCHP） system with a core of gas engine and adsorption chiller was analyzed from the optimal operation point of view. By taking the minimal operation cost meeting the load demand of cooling, heating and power as optimizing function, the economic optimization model of the micro-CCHP system was established. The specific optimum operational strategy of the system was obtained with real projects, and it was explored that the micro-CCHP system has the as- surance of economic benefits. The study results indicate that the optimal operation mode is associated with energy price. Under identical natural gas price, the higher the electrical price, the better the micro-CCHP system＇s economic feature is.
