摘　　要：针对建筑围护结构的节能效果、风冷热泵结合不同空调末端的能耗的问题,利用模拟软件Dest对该建筑从保温围护结构、机组能耗两个方面进行了分析。该建筑围护结构中采用导热系数小于等于0.03 W/(m2.K)保温板,采用风冷热泵结合室内毛细管辐射加新风系统的新型空调系统。在新型空调系统下,采用保温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27.8%、15.0%。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18 911.89、25 255.46 kW.h。As to the energy saving of the building envelope and the energy consumption of the air-cooled heat pump under different terminal unit modes, the paper analyzed the energy saving of the building in Shanghai from the insulated building envelope and the heat pump power consumption by simulation software Dest. The insulation board whose heat-transfer coefficient is less than or equal to 0.03 W/（m^2·K） was adopted in the building envelope, and the new fashioned air-conditioning system of the air-cooled heat pump combining the indoor capillary system of radiation and the fresh air system was used. Compared between the insulated building envelope and the non-insulated building envelope, the reduction percentage of peak loads caused by the insulated building envelope on January 23 and July 21 were 27.8% and 15.0% under the new air-conditioned system. Compared between the fan-coil and the fresh air system, the reduction of the annual heat pump power consumption from heating and cooling of the new system is 18 911.89 and 25 255.46 kW.h.
