Simulation research on correlation between cold source configuration and load characteristics of central air conditioning systems
摘要：
同样供冷需求下不同冷源方案的运行能耗不同，其主要影响因素为建筑全年空调负荷分布特性。以厦门市某栋公共建筑集中空调系统为例，对比分析了4种不同冷水机组台数及单机制冷量配置方案，提出了以冷负荷数据分析为基础的冷源优化配置初选计算方法和模拟计算方法。同时，研究了不同负荷特性与冷源配置之间的规律，分析总结了集中空调系统冷源配置的一般性规律和设计方法。
Abstract：
The study finds that the operating energy consumption of different cold source schemes will be different under the same cooling demand, and the main influencing factor is the annual air conditioning load distribution characteristics of the building. Taking the central air conditioning system of a public building in Xiamen as an example, this paper compares and analyses four different chiller units and single cooling capacity configuration plans, and proposes a calculation method for the primary selection of cold source optimal configuration based on cooling load data analysis. At the same time, the law between different load characteristics and cold source configuration is studied, so as to analyse and summarize the general law and design method of cold source configuration of the central air conditioning system.
