摘要：
以降低公共建筑能源系统运行能耗、助力建筑供热电气化、提高可再生能源利用率为出发点,介绍了某办公楼+酒店综合体工程利用地源热泵、市政热力、冷水机组等组成串并联相结合的复合式能源系统的设计思路。利用模拟软件进行了动态仿真,对热平衡运行策略、运行能耗等作了对比分析,结果表明该复合式能源系统具有较好的节能和环保效益。
Abstract：
Beginning with the goal of reducing the operational energy consumption of public building energy systems, promoting the electrification of building heating, and enhancing the utilization of renewable energy sources, this paper presents the design concept of a composite energy system for an office-hotel complex project, which integrates ground-source heat pumps, municipal heat, and chiller units in a combined series and parallel configuration. The dynamic simulation is carried out by using the simulation software, and the thermal equilibrium operation strategy and operational energy consumption are compared and analysed. The results show that the composite energy system has good energy saving and environmental protection benefits.
