摘要
从能流对比分析角度出发,通过阐述从空调房间提取热量到最终排放到室外大气环境系统的整体能流情况,建立了分别以水冷冷水机组和风冷冷水机组为冷源集中空调系统的能流数学模型;以广州某综合性建筑为例,分别绘制了两种冷源夏季供冷设计工况下的能流图,并从系统的整体能流方面对比分析了各环路能流的差异,为系统的冷源优选和整个系统的节能提供参考和依据。
Through the state the extract heat from the room to the outdoor environment, the two energy flow mathematical model for the central air conditioning system with water-cooled chiller and air-cooled chiUer were respectively established from the aspect of the comparative analysis of energy flows. As a case study, the two energy flow diagrams of a summer design condition for cooling mode of a comprehensive building in Guangzhou were drawn. Recognize the two energy flow differences from a global air conditioning system, and put forward references and basis for the selection of cold sources and the energy saving for the system.
