摘　　要：当前多联机系统设计阶段缺乏工程能效预评估方法,导致无法预估多联机产品应用于实际工程后的能效,是阻碍多联机高效应用的难题。文章探讨了产品性能评价标准在评价实际工程系统性能的不足,提出根据多联机产品在试验室环境下的测量数据,预估其用于实际工程设计的多联机工程季节性能评价方法,研究表明:铭牌APF为4.71 Wh/Wh的多联机应用于不同城市的系统工程能效比范围在2.70~4.55 Wh/Wh之间。应用工程能效评价方法能够为不同地区应用多联机时提供节能设计指标,为促进多联机的高效设计应用提供重要支撑。The lack of engineering energy efficiency pre-assessment methods at the design stage of multi-split variable refrigerant flow(VRF)air-conditioning system leads to the inability to predict the energy efficiency of VRF products after application,which hinders the efficient application of VRF system.This paper discusses the inadequacy of product performance evaluation standards in evaluating the performance of actual applied systems,and proposes a seasonal performance evaluation method forVRF system in real building based on the measurement data from laboratory.The study shows that the engi-neering energy efficiency ratios of VRF(with nominal annual performance factor of 4.71 Wh/Wh)applied in different cities range from 2.70Wh/Wh to 4.55Wh/Wh.The e-valuation method is applied to provide energy-saving design indicators for VRFused in dif-ferent regions,and promotes the efficient design and application of VRF system.
