通过分析水冷冷水机组中央空调系统供应冷量的空调房间提取热量到最终排放到环境中的5个连续子环路的能流情况，建立了以水冷冷水机组为冷源的中央空调系统整个环路的能流分析模型。并通过实验测试获得了广州某一次回风定风量全空气集中空调系统运行的相关数据，绘制了该系统的能流图，定量分析了系统内各部分的能流变化规律及能流之间的关联性，直观地表达出该系统中各能流的大小和方向，以及各系统的能量平衡关系及能量损失，并识别出系统的主要能流，为中央空调系统的能耗分析及节能提供了理论分析模型。

Through analyzing the energy flow of five consecutive loops extracting energy from the air-condi-tioned rooms to the surroundings, this paper proposes an energy flow mathematical model of the whole air conditioning loop with water-cooled chiller, and draws an energy flow diagram based on the data derived from a typical all-air system of an office building at Guangzhou.It also quantitatively discusses the varia-tion principles and relations of energy flow, presents the magnitude and direction of energy flow, energy balance and loss of systems as well as recognizes the dominant energy flows.Finally, a theoretical analyt-ic model is suggested for the energy-consuming and energy-saving of central air conditioning system.
