摘　　要：研究太阳能联合城市燃气锅炉供暖系统的节能设计优化方案。设计集太阳能集热器、蓄热水箱、换热器、水泵、燃气锅炉等重要设备于一体的联合供暖系统,分析串联供暖与并联供暖组合方式,以及适用于联合供暖组合的太阳能单独供暖、同时供暖、燃气锅炉单独供暖三种供暖模式,采用TRNSYS构建串联供暖系统与并联供暖系统模型,对串联供暖系统与并联供暖系统节能设计进行比选,并从运行经济性角度出发优化联合供暖系统容量匹配节能设计。串联供暖系统节能设计比并联供暖系统节能设计的太阳能保证率高、系统性能好、系统能耗低。The paper studied design optimization of urban heating system supplied by solar energy and gas boiler.A combined heating system containing solar collectors,heat storage tanks,heat exchangers,water pumps and gas boilers was designed to analyze the effects of series heating and parallel heating,as well as three heating modes including solar heating,gas boiler heating and combined heating.TRNSYS was adopted to build models of series and parallel heating systems,so as to optimize energy-saving designs based on principle of operational economy.Compared to parallel heating system,the energy-saving design of series heating system has a higher solar energy guarantee rate,better system performance and lower energy consumption of system.
