摘　　要：在分析现行节能标准建筑与超低能耗建筑冷热负荷的基础上，对比北京某办公建筑在现行节能标准建筑与超低能耗建筑标准下的负荷差异，相对现阶段节能标准建筑，建筑热负荷大幅减小，冷负荷则变化不大，同时负荷分布更均匀。通过Fluent软件模拟北京地区在设计工况下单孔地埋管换热器运行30d的运行性能。最后，在超低能耗建筑标准下，采用TRNSYS软件模拟土壤源热泵时机组的相关性能参数。随后通过TRNSYS模拟比较不同钻孔深度与钻孔间距时土壤源热泵系统性能差异。The load differences of an office building in Beijing under the current energy-saving building standard and ultra-low energy consumption building standard is compared based on the analysis of the current energy saving building standard and the cold and heat load of the ultra low energy consumption buildings. The results show that compared with the energy-saving standard building at this stage, the thermal load of building is greatly reduced, and the cold load just has a little change, at the same time the load distribution is more uniform. And the FLUENT software is used to simulate 30 days operation performance of single-hole buried tube heat exchanger in Beijing under the design conditions. Finally, the TRNSYS software is used to simulate the performance parameters of the soil source heat pump system under the ultra low energy consumption building standards. Then the performance differences of soil source heat pump systems under the different drilling depth and spacing are simulated and compared by the TRNSYS software.
