摘　　要：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(VRF)能耗算法,并开发相应的计算模块;同时,建立VRF实验测试系统,在冬季测试数据的基础上,进行能耗仿真比较验证。结果表明,平均供热量和耗电量误差分别为34.97%和26.51%,VRF能耗计算模块能够追踪EnergyPlus负荷计算的精度,并且正确反映机组的能耗特性。Proposes an algorithm suitable for VRF dynamic energy calculation, and develops the new simulation module on the basis of the building energy simulation program EnergyPlus from United States Deportment of Energy. Builds a VRF set-up to validate the simulation module by a comparison with measurements under heating condition. Proves the differences between average monitored and predicted data for the total heating capacity and power use which are within 34.97% and 26.51%, respectively. Also, the VRF simulation module is able to track the accuracy of load calculation in EnergyPlus and map the energy performance of the VRF system correctly.
