摘　　要：针对典型气候区(郑州和哈尔滨)不同建筑类型的负荷特点,提出多能源时序互补集中式供暖系统,并对蓄热场的蓄取规律进行模拟分析。通过TRNSYS模拟,对多能源时序互补集中式供暖系统在不同建筑中运行时的蓄热场土壤平均温度、系统运行策略、能效提升率进行分析。结果表明:土壤平均温度处于动态平衡,公建系统土壤平均温度最高可达65℃;公建及寒冷地区居建系统运行策略均以太阳能直供和蓄热场直供为主要供热方式,地源热泵为辅,严寒地区居建系统运行策略是以地源热泵为主要供热方式,太阳能直供和蓄热场直供为辅;多能源时序互补集中式供暖系统与地源热泵系统相比能效提升明显,公建系统能效可提升90%以上,严寒地区居建系统能效提升59.12%。According to the load characteristics of different building types in typical climate zones(Zhengzhou and Harbin),a multienergy sequential complementary central heating system was proposed,and the storage and extraction law of heat storage field was simulated and analyzed.Through Trnsys simulation,the average soil temperature of heat storage field,system operation strategy and energy efficiency improvement rate of multi-energy sequential complementary central heating system in different buildings were analyzed.The results showed that the average soil temperature was in dynamic equilibrium,and the highest average soil temperature was 65℃in the public system.The operation strategy of the residential construction system in public buildings and cold areas takes solar direct supply and thermal storage field direct supply as the main heating mode,supplemented by ground source heat pump.The operation strategy of residential construction system in cold areas takes ground source heat pump as the main heating mode,and solar direct supply and thermal storage field direct supply as the auxiliary.Compared with the ground source heat pump system,the energy efficiency of the multi-energy sequential complementary central heating system is significantly improved.The energy efficiency of the public construction system can be increased by more than 90%,and the energy efficiency of the residential construction system in the cold area is increased by 59.12%.
