摘　　要：为了评价变频多联空调机组的能耗特征,在美国能源部动态建筑能耗模拟软件EnergyPlus的基础上,提出适合于动态能耗计算的变频多联空调能耗算法,并开发相应的计算模块,进而在一典型的小型商业建筑模型基础上,与屋顶式整体机组作建筑物总能耗比较分析。仿真结果表明,相比屋顶式整体机组,变频多联空调有16.3%的节能潜力。In order to evaluate the energy feature of VRF units, proposes an algorithm and developes a new module for the dynamic VRF energy calculation, based on the soft ware EnergyPlus of the US Department of Energy （DOE）. Implements energy comparison with roof-top unit in a typical small-sized commercial building. The result shows that VRF owns the energysaving potential of 16.3 %, compared with the roof-top unit
