摘　　要：针对中央空调系统节能运维数据的缺失或数据种类单一以及实验条件不足的难题,设计并搭建了一种用于模拟实际空调房间热湿负荷工况的缩尺中央空调实验平台。根据研究需求,通过LabVIEW实现对实验平台的自动控制,可对主机运行台数、风机及水泵频率、加热棒加湿器进行远程设置并稳定运行,构建大量中央空调系统不同工况下运行数据,为空调系统节能研究提供实验平台基础。实验数据表明,本实验平台的水力工况与热力工况符合实际,能够进行多水平、多因素的试验,从而得出准确可靠的运行结果,为中央空调局部以及系统研究提供实验平台基础。Aiming at the problems of missing or single data type and insufficient experimental conditions of energy-saving operation and maintenance data of central air conditioning system,a scaled central air conditioning experimental platform was designed and built to simulate the heat and humidity load conditions of actual air-conditioned rooms.According to the research requirements,the automatic control of the experimental platform can be realized through LabVIEW,which can manually set the number of main machine,frequency of fan and water pump,and heating bar humidifier and run stably.A large amount of operation data of central air conditioning system under different working conditions can be built,which provides the experimental platform foundation for the research of air conditioning system energy saving.The experimental data show that the hydraulic and thermal conditions of the experimental platform are in line with the reality,and the multi-level and multi-factor tests can be carried out,so as to obtain accurate and reliable experimental results.
