摘　　要：为了测试房间空调器实际动态运行时的能效,文章提出了一种基于虚拟负荷房间空调器动态运行能效测试方法,并通过改造空气焓差试验室实现了空调器的动态运行能效测量。动态能效测试结果表明:1)实现了室内干湿球温度按照空调近实际运行状态进行动态变化;2)制冷、制热工况的室内干湿球温度跟随性良好,设定值与实际值的平均误差在0.5℃范围之内;3)在动态测试过程中,空调能力与建筑热负荷动态协调,使得空调按照自有控制逻辑动态运行,提出的方法能够获得制冷、制热工况的空调动态运行能效。In order to test dynamic energy efficiency of air conditioner during actual op-eration,this study proposed a dynamic energy efficiency testing method for room air con-ditioners based on virtual heat loads,and achieved dynamic energy efficiency measurement of air conditioners through the transformation of the air enthalpy laboratory.The dynamic energy efficiency test results showed that:1)the indoor wet bulb temperature and dry bulb temperature could dynamically change according to the actual operating state of the air conditioner;2)The indoor wet bulb temperature and dry bulb temperature tracking performance under cooling and heatingconditions was good,and the average error between the set value and the actual value was within the range of 0.5℃;3)During the dynamic testing process,the air conditioner capacity is dynamically coordinated with the building heat load,allowing the air conditioning to operate dynamically according to its n-ative control strategy.The proposed method could obtain the dynamic operating energy ef-ficiency of the air conditioner under cooling and heating conditions.
