摘　　要：为评价变频多联空调(VRV-II,以下简称VRV)的能耗特征,在建筑能耗动态模拟软件EnergyPlus的基础上,开发了VRV的能耗计算模块,并在一典型的商业建筑模型基础上,与几种常见的空调系统方案作了建筑物总能耗仿真比较。结果表明,VRV是最为节能的方案。同时,对于传统的空调系统,作为冷源方案的水冷式螺杆机相比风冷式螺杆机、以及作为系统方案的风机盘管加新风相比变风量空调,都显示出更为节能的特性。To evaluate energy consumption features of the new-generation variable refrigerant volume （VRV-Ⅱ） system, an energy calculation module for the system was developed based on the dynamic building energy simulation program, EnergyPlus. A building energy comparison analysis among the VRV system and several popular air conditioning systems was implemented, using a typical commercial building model. Simulation results show that the VRV system is the most energy-efficient plan. For the traditional systems, the water-cooled screw chiller is more energy efficient than the air-cooled screw chiller as the plant scheme, and the Fan-coil plus outdoor-air system are found more energy efficient than the variable-air-volume system as the system plan.
