摘　　要：为评价变频多联空调(VRV)的能耗特性,基于美国能源部动态建筑能耗模拟软件EnergyPlus开发了VRV的能耗计算模块。利用一实际建筑作算例,在不同室内设定温度、不同室内机开停台数的情况下对变频多联空调系统的性能系数和部分负荷比以及室外温度和机组能耗的关系进行了计算分析,并与文献中的实验结果作了对比验证。结果表明,所开发的计算模块能够较好地分析变频多联空调系统的能耗特性。Based on the building energy simulation program, namely EnergyPlus, a new algorithm for energy usage calculation of a variable-refrigerant-volume （VRV） air conditioning system was proposed, and a new module was then developed. The objective was concerned with the evaluation of energy consumption of the VRV system. A typical VRV system used in a real office building was calculated in this paper. Its coefficient of performance （COP） and part load ratio （PLR） were given at various set points of indoor temperature, and the relationship between the outdoor temperature and energy consumption of the VRV system was obtained. The simulation results show that the energy consumption features of VRV for the building can be analyzed very well by this developed program.
