摘　　要：以天然气为燃料的冷热电联供系统因其节能、环保等特性而引起广泛重视,其设备选择多样化、系统集成方案多样化,在方案的优化设计中考虑设备类型、设备参数、系统结构等关键因素。文中选择微型燃气轮机,溴化锂制冷机的关键参数作为优化设计的变量,考虑了热水型溴冷机和烟气型溴冷机两种情况,并引入夹点理论引对系统结构进行优化,从而对冷热电联产系统的整体优化进行了研究。结果表明,该方法可以有效对冷热电联产系统进行理论优化,为工程实际优化奠定了基础。The Combined Cooling Heating and Power（CCHP） system with natural gas as fuel for its characteristics such as energy saving, environmental protection, attracted widespread attention. Because of the diversifieation of equipments and systems structure for CCHP, the device parameters, device type and system structure must be taken into aeeount in the devices optimiza- tion for CCHP. The key parameters of micro - gas turbines and lithium bromide refrigerator were selected for optimization design in this paper. The hot - water type lithium bromine refrigerator and gas type lithium bromine refrigerator were considered, and the pinch point theory was introduced into the system structure optimization. Thus the CCHP system optimization was studied. Re- suits show that the method inthispaper can be effective to optimize CCHP system in theory.
