摘 要: 空调冷热源的优化控制的研究包括数学模型的建立、模型参数的辨识和优化算法等三方面。在空调冷热源的优化控制模型中,通过构造惩罚函数,把原来的约束问题转化为无约束的优化问题。为了能较好地处理离散参数和约束条件,优化算法采用二进制编码的遗传算法,对冷热源系统运行参数进行优化。为了验证冷热源系统自适应优化控制模型的有效性,利用长沙某出版社的空调冷源系统对优化模型进行了检验。经计算分析,优化后的系统能耗比优化前节能约7%。 The research on optimal control model for building cooling and heating sources focuses on mathematic models for devices, model parameter identification and optimal algorithm. In the optimal control model, the penalty fimction is constructed to transform constrained optimization problem into unconstrained optimization problem according to the objective function and constraints. In the optimization for building cooling and heating sources, the genetic algorithm (GA) is used to deal with discrete variables and constraints. A HVAC system is studied in a press to test the optimal control model for building cooling and heating sources. After optimized, the energy consumption of the HVAC system is saved by about 7%.
