摘　　要：本文研究了基于动态负荷的多联机能效测试方法及其可行性。传统的多联机能效测试标准主要基于稳态工况,无法全面反映系统在动态条件下的性能。基于动态负荷的测试方法通过模拟空调与实际建筑负荷的动态交互,能更真实地评估空调系统在真实环境中的动态响应能力和整体能效。本文探讨了将该测试方法应用于多联机系统的关键技术点,包括虚拟建筑模型的扩展以适应多区域负荷需求、多点控制和监测的实现、复杂负荷响应的模拟、系统启动和调节动态评估以及实验室设置的调整。基于动态负荷的多联机能效测试方法在技术上是可行的,但经济上需要较高的成本和资源投入。This paper investigates the testing method for multi-split air-conditioner efficiency based on dynamic load and its feasibility.Traditional testing standards for multi-split systems,mainly based on steady-state conditions,do not comprehensively reflect the system’s performance under dynamic circumstances.By simulating the dynamic interac-tion between air conditioning and actual building load,the dynamic load-based testing method can more realistically evaluate the dynamic response capability and overall energy efficiency of the air conditioning systemin real-world en-vironments.This study explores key technical points for applying this testing method to multi-split systems,including the extension of the virtual building model to accommodate multi-zone load requirements,the implementation of multi-point control and monitoring,simulation of complex load responses,dynamic evaluation of systemstartup and regulation,and adjustments to laboratory settings.Although dynamically load-based testing for multi-split systems is technically feasible,it requires higher economic costs and resource investment.
