摘　　要：首先通过分析得出商场内各产热单元的冷负荷,给出商场内总冷负荷关于人流量和商场温度的表达式;然后分别用优化方法和解超定方程方法求出商场内人流量随时间的变化;最后采用全局优化原理对中央空调系统的节能控制进行建模,实现了整个中央空调系统的能耗最小化.This paper firstly presents the expressions of cooling load of the emporium in terms of the population flow and the temperature inside the market, based on the analysis of thermogenetic units in the emporium. Secondly, the time-dependent visitors flowrate is given by using both methods of optimization and solving overdetermined equations. Finally, the model of energy economizing control for central air conditioning system is built by means of the principle of global-optimization, and makes the energy saving of all central air conditioning system come true.

关 键 词：中央空调系统 冷负荷 节能 全局优化
