摘　　要：本文以EnergyPlus模拟软件中的分体式空气源热泵和带有地板辐射供暖末端的地下水源热泵系统为例,研究分散和集中供暖方式在供暖季的运行能耗。模拟结果表明:在分室分时供暖需求模式下,分散式供暖较集中式供暖能耗略少。而在全室全时供暖需求模式下,集中式供暖较分散式供暖能耗小,且纬度越高的城市,节能优势更明显。导致该分散与集中供暖能耗差异性的主要原因是各自系统调控性与能效水平的差异性。模拟结果还表明,无论是分散还是集中系统,分室分时供暖模式比全室全时供暖模式能耗明显要小。This paper takes the packaged terminal heat pump and ground water source heat pump system with radiant floor heating terminal in EnergyPlus simulation software as examples to study the energy consumption of decentralized and centralized heating mode in heating season.The simulation results show that the energy consumption of decentralized heating is slightly less than that of centralized heating under the demand mode of part-time and part-room heating.While the energy consumption of centralized heating is less than that of decentralized heating under the demand mode of full-time and full-room heating.And the higher latitude the city,the more obvious the energy saving advantage.The main reason for the difference of energy consumption between decentralized and centralized heating systems is the difference of regulation and energy efficiency of their respective systems.The simulation results also show that the energy consumption of part-time and part-room heating mode is significantly lower than that of full-time and full-room heating mode in both decentralized and centralized systems.
