摘要/Abstract

摘要： 主要研究空调系统一定温度要求下的表冷器最小能耗优化控制。介绍了空调系统仿真软件HVACSIM+模拟空气处理系统所需的主要数学模型；对西安地区某建筑的空气处理系统和空调房进行仿真。建立表冷器的能耗与冷冻水流速之间的函数关系，并将此作为目标函数。应用变量轮换法优化PID控制器参数，计算冷源向空调系统提供的能耗。结果表明，所建立的仿真系统运行稳定，且表冷器能耗与优化前相比大大减少。

Abstract: The optimized control of minimizing energy consumption in one air-conditioning system was studied. The main models that needed in the simulation software HVACSIM+ for air handling unit were introduced. The AHU and rooms of the first floor of certain Building were taken as the simulation target. Then the function describing the relation between the consumption of cooling coil and the chilled water velocity was found and taken as the objective function. With improved cyclic variable method, the controller^ parameters were optimized. Results show that the simulation system runs steadily while the controller works with the optimal parameters, and the energy consumption of the cooling coil is greatly reduced compared with working in non-optimizing condition.

Key words: air conditioning, optimal control, cyclic variable method, cooling coil
