摘　　要：针对建筑围护结构的节能效果、土壤源热泵结合不同空调末端的能耗及其地下热平衡问题,本文通过模拟软件Energyplus从保温围护结构、机组能耗两个方面分析了某厂房建筑的节能性;研究了地下热平衡问题的解决方案。该建筑围护结构中采用传热系数小于等于0.03 W/(m.2K)保温板,采用土壤源热泵结合室内地板辐射加新风系统的新型空调系统。在新型空调系统下与不保温围护结构相比,该建筑保温围护结构使1月23日和7月21日的峰值负荷分别减少20.6%、24.9%。在保温围护结构下与室内风机盘管加新风系统相比,该新型空调系统的机组供暖、供冷能耗每年减少4420 kWh、8000 kWh。Focused on energy saving of building envelope, energy consumption of ground-coupled heat pump combined with different terminal unit modes and underground heat balance problem, energy saving analysis in terms of insulation building envelope and heat pump power consumption in a factory building was carried out and solutions to the underground heat balance problem was studied by simulation software Energyplus. Insulation board whose heat-transfer coefficient is less than or equal to 0.03 W/（m^2·K） is adopted in the building envelope and ground-coupled heat pump combined with radiant floor and fresh air system is adopted as the new fashioned air-conditioning system. Compared to no insulation building envelope, the reduction percentage of peak loads caused by insulation building envelope on January 23 and July 21 are 20.54% and 24.92% with the new fashioned system. Compared to fan-coil and fresh air system, the reduction of annual heat pump power consumption of radiant floor and fresh air system are 4420 kWh and 8000 kWh during heating and cooling with the same insulation building envelope and ground-coupled heat pump.
