不同负荷特性下集中空调系统冷源配置优化计算方法

Optimization calculation method for cold source configuration of central air conditioning systems under different load characteristics

以逐时冷负荷数据的变异系数作为负荷特性指标,比较了4种典型气候条件下不同冷源配置方案的运行能耗,得到不同气候条件(不同负荷特性)下集中空调系统冷源配置规律,建立了以逐时冷负荷变异系数、冷源小机单机容量占比为变量的冷源配置优化数学模型。

This paper uses the coefficient of variation of hourly cooling load data as the load characteristic index,compares the operating energy consumption of different cold source configuration schemes under four typical climatic conditions,and derives the law of cold source configuration of central air conditioning systems under different climatic conditions(different load characteristics).An optimization mathematical model for the cold source configuration with the hourly cold load variation coefficient and the single unit capacity proportion of small units as variables is established.
